ERCOT Technical Advisory Committee Briefs: May 24, 2018

AUSTIN, Texas — ERCOT’s legal department again delayed votes endorsing final changes to the grid operator’s bylaws and articles of incorporation, saying it needed additional time to evaluate a last-minute comment from Luminant.

Assistant General Counsel Vickie Leady told the Technical Advisory Committee last week that legal staff would delay final votes on the revisions until the August set of leadership meetings. She said ERCOT and Luminant are “on the same page,” but they are trying to figure out the language.

“We appreciate having people poke holes in the language,” Leady told the TAC during its May 24 meeting. “Given the importance and relative permanence of the language, we need more time to address it. Once we put stuff in the bylaws, it’s there for a long, long time.”

Legal staff had originally planned to put the proposed changes up for votes in April but pushed the final recommendation back to the June Board of Directors meeting. (See “ERCOT Legal Staff Delays Bylaw Revisions,” ERCOT Technical Advisory Committee Briefs: March 22, 2018.)

Luminant sent its comments after working hours on May 23, suggesting clarifications to the proposed affiliate definition. The generating company added language to the definition that read:

“A person who is not controlling, controlled by or under common control with another person as described above may nonetheless be determined to be an affiliate of another person, if ERCOT or a member alleges that such exercises directly or indirectly, through one or more intermediaries, substantial influence over another person. Such a determination may be made by the board only after notice and an opportunity for hearing at an ERCOT board meeting. The burden of proof to show substantial influence is on ERCOT or the member alleging such influence.”

Luminant’s Ian Haley apologized for the late filing, saying it was the first time the company had been able to gather together its legal counsel.

The company also suggested a central repository for the various clean and red-lined documents, which Leady said ERCOT would follow. Legal staff also plan to hold a workshop following the June board meeting to “facilitate a final set of comments.”

Leady said she has received no stakeholder comments on the articles of incorporation but that they should “travel together” with the bylaw changes.

Southern Cross Transmission (SCT) also filed comments requesting a delay of a decision regarding in which market segment it should be placed. SCT believes it should be included in a newly created DC Tie Operator segment.

Cratylus Advisors’ Mark Bruce, who represents the project’s developers, said SCT hopes that when the market segment question is revisited, “greater stakeholder familiarity with the SCT project will ease some of the controversy currently associated with the question of the appropriate market segment assignment for DC tie operators.”

Bruce wrote that he saw no harm in delaying the membership decision. Leady said staff would “reinitiate” stakeholder discussion of the segment definition “upon further certainty that the SCT project will be interconnected” to ERCOT.

Southern Cross is a proposed HVDC transmission project in East Texas that would be capable of shipping more than 2 GW of energy between the Texas grid and Southeastern markets. (See “Members Debate Southern Cross’ Bid to be Merchant DC Tie Operator,” ERCOT Technical Advisory Committee Briefs: Feb. 22, 2018.)

Texas’ Public Utility Commission last year directed ERCOT to address several issues as a condition for energizing SCT’s project. The conditions include determining “the appropriate market participation category for [SCT] and for any other entity … for which a new market-participant category may be appropriate” (Project No. 46304).

Staff Recommend 2 Transmission Projects

The committee endorsed staff’s recommendation of a $327.5 million Oncor project that addresses reliability concerns in ERCOT’s Far West region.

If approved by the Board of Directors in June, Oncor’s work will include building 40 miles of new 345-kV lines on double-circuit structures, adding two new 600-MVA, 345/138-kV autotransformers at a switch station, installing a second 345-kV circuit between Odessa and Riverton, and building two 20-mile segments of 138-kV line on double-circuit structures.

Construction is expected to begin next year, with completion in 2023.

Staff said the project will provide operational flexibility and resolve potential reliability issues in the face of oil and gas-related load growth.

Staff also shared with TAC members an additional study evaluating a Rayburn Country Electric Cooperative proposal to transfer its existing facilities and load into ERCOT, a plan filed last year with the PUC (Docket No. 47342).

The ISO said it is now recommending a “modified alternative option” to integrating Rayburn’s load, following an Oncor study of a transmission alternative than eliminated a 345-kV interconnection.

Staff concluded the second option, which still includes two 138-kV interconnections, has “similar reliability and long-term load-serving capability.” However, the modified alternative has a lower estimated capital cost of $31.7 million, leading ERCOT to propose the Oncor suggestion.

Staff’s initial study indicated capital costs of $41.7 million.

Rayburn, which sits on the ERCOT-SPP seam in East Texas, has proposed transferring load and transmission facilities into ERCOT. The co-op is an SPP member, but only about 150 MW (or less than 20%) of its load and 160 miles of its transmission sit in the Eastern Interconnection. (See “ERCOT, SPP Agree to Rayburn Country Migration Studies,” Public Utility Commission of Texas Briefs: Aug. 31, 2017.)

Members Approve Subcommittee’s Restructuring

Members unanimously approved a task force’s recommendation to designate the Commercial Operations Subcommittee (COPS) and several of its working groups as inactive, agreeing that it has reached a “steady state” situation concerning market communication and settlement issues.

The Wholesale Market Subcommittee will inherit the Settlement Working Group and the Commercial Operations (COP) Market Guide, while the Retail Market Subcommittee will pick up the Profiling Working Group, Load Profiling Guide and market communications.

The TAC Subcommittee Restructuring Task Force brought its recommendations to the committee in February. (See “Committee Endorses Task Force Restructuring Recommendations,” ERCOT Technical Advisory Committee Briefs: Feb. 22, 2018.)

The restructuring will require the following changes for the COP Market Guide and the Load Profiling and Retail Market guides:

  • COPMGRR047: Relocates the COP guide to the WMS, moves other portions of the manual to the retail guide and removes language that is no longer applicable from the COP guide.
  • LPGRR064: Moves the Load Profiling Guide and load-profiling responsibilities from COPS to the RMS and removes language from the guide that no longer applies.
  • RMGRR151: Incorporates the market notice communication process and renewable energy credit information from the COP guide into the retail guide.

The task force will continue its development of a “three strikes” attendance policy for TAC and its subcommittees, whereby seated segment representatives that miss three meetings or fail to assign an alternate for those meetings will lose their seats. It will also aid the RMS with moving RMGRR151’s market notice process language into a standalone Other Binding Document.

TAC Re-elects Helton as Chairman

TAC once again elected Bob Helton as its chair, an action required following the latest change in his employment status and market segments.

Helton moved from ENGIE to Dynegy last year when the latter bought the former’s 17 U.S. power plants. He left Dynegy when it was subsequently acquired by Vistra Energy, recently rejoining ENGIE as its director of government and regulatory affairs.

“I know you guys may not know this person, and I know we’ve elected him three times in the last seven months,” began Sharyland Utilities’ B.J. Flowers as she teasingly nominated Helton for the vacant chair position.

Helton thanked the members for their support, saying he hopes to finish out the year as committee chair.

“Of course, you never know, the way jobs change around here,” he joked.

Committee Endorses 4 NPRRs, 7 Other Changes

The committee endorsed four Nodal Protocol revision requests, a revision to the Nodal Operating Guide, a pair of Other Binding Document revisions, two changes to the Planning Guide and two changes to the Verifiable Cost Manual.

  • NPRR847: Incorporates an intraday or same-day weighted average fuel price into the mitigated offer cap to ensure that resources are capped at the appropriate cost during high fuel price events and LMPs reflect the true incremental cost of fuel.
  • NPRR851: Establishes a clearly defined disconnection process within the market rules applicable to a transmission voltage connection to the grid that uses one electrical connection for both generation and load services.
  • NPRR867: Caps the amount of each counterparty’s available credit limit locked for congestion revenue rights auctions at the pre-auction screening credit exposure amount.
  • NPRR870: Deletes the gray-boxed requirement for ERCOT to post a forward adjustment factors summary report on the Market Information System’s certified area. The information in this report is already provided on each counterparty’s estimated aggregate liability summary report.
  • NOGRR176: Clarifies that all transmission owners and qualified scheduling entities representing resources can participate in ERCOT hotline calls.
  • OBDRR004: Revises the risk-weighting factors available for assignment to each emergency response service (ERS) time period; describes the process for updating the ERS time period expenditure limits for any subsequent standard contract terms (if money is needed to fund) and the ERS renewal contract period; and updates a table to reflect the risk-weighting factors’ proposed changes.
  • OBDRR005: Revises the generic transmission constraint (GTC) shadow price cap that is used in SCED for base case constraints from $5,000/MWh to $9,251/MWh. The revision also updates the associated examples in SCED and makes an administrative edit to a protocol reference.
  • PGRR059: Includes Regional Planning Group-related changes intended to improve and clarify existing processes.
  • PGRR060: Updates the reliability performance criteria by defining a DC tie’s unavailability as a new contingency and clarifies the voltage level of transformers referred to in the reliability performance criteria.
  • VCMRR020: Delays VCMRR014’s sunset date to permit stakeholders additional time to find a long-term solution that determines an appropriate adder for coal- and lignite-fired generation resources.
  • VCMRR021: Aligns the VCM with the language proposed in NPRR847 by removing language providing for make-whole payments for exceptional fuel costs. The costs will be recovered in NPRR847.

Overheard at NECPUC 71st Annual Symposium

CAPE NEDDICK, Maine — The future of the grid, electric vehicles, high costs, and the tension between state and federal jurisdiction were among the topics discussed at the New England Conference of Public Utilities Commissioners’ (NECPUC) 71st annual symposium last week.

New England faces “some of the highest costs in the country, resource constraints, reliability concerns, retirement concerns, storm costs, increasing resiliency needs — and that’s just right now,” said Elin Katz, Connecticut consumer counsel and president of the National Association of State Utility Consumer Advocates.

“I get really frustrated when people dismiss the advocate perspective and say all you care about is cost, because I love technology,” Katz said. “But I’m really worried about the cost.”

Katz serves on a scholarship board for the University of Hartford, where she said this season’s applicants are poorer, needier and have higher needs than the year before.

“That’s happening all over the country … so I worry about the consumer and what is happening with respect to our consumers and what they can afford,” Katz said.

Maine Wants Lower Prices

Cost was also on the mind of Maine Gov. Paul LePage, who told NECPUC on May 22 that he is looking to Canada to help supply his state with natural gas because his state has so far been unable to access the plentiful Marcellus gas in Pennsylvania because of environmentalists’ opposition to pipelines.

“You can live in Montreal, have a flat in the most expensive part of town and heat with electricity” because of low-cost Canadian hydropower, LePage said.

Maine enjoys the cheapest electricity prices in New England, but the region has the highest prices in the country, so the distinction means nothing when the state competes against Alabama for a new manufacturing plant, he said.

LePage brought up the case of an aircraft manufacturer looking to site a new plant. The $600 million cost of building in Alabama beat the $200 million cost in Maine because of the cheaper electricity rates in Alabama, he said.

LePage said high power prices are particularly challenging for the aging demographic in Maine, where many residents are retired and live on fixed incomes.

Resilience and the State/Federal Divide

The debate over grid resilience has highlighted new tensions in the line between state and federal jurisdiction, former FERC Commissioner and North Dakota PSC Chairman Tony Clark said.

“We thought [resilience] was basically about black start resources — the grid goes down and you have to have certain resources available that can bring the grid back up fast,” said Clark, now an adviser with law firm Wilkinson Barker Knauer.

Now regulators are asking about the value of fuel diversity, onsite fuel storage, dual-fuel units and the risk of gas generators with single-source pipelines.

“Some of those things begin to look an awful lot like resource adequacy, and once you start straddling that resource adequacy divide, you’re right in the middle of that state-federal jurisdictional pull,” Clark said.

Montana Public Service Commission Vice Chair Travis Kavulla said, “There’s no honest man in the conversation or debate about which jurisdiction is better, because utilities will opportunistically latch onto either side that’s perceived to maximize their profit, and the same goes for the rest of the stakeholders.

“This jurisdictional strife should probably be understood to be, as much it’s a function of law, as a function of rent-seeking or its first cousin, regulatory arbitrage,” Kavulla said.

In the absence of federal authority, there’s only so much states can do, said Kate Konschnik, director of the Climate & Energy Program at Duke University’s Nicholas Institute for Environmental Policy Solutions.

“One things states cannot do is reach into other states and dictate policy across state lines,” Konschnik said, referring to the Supreme Court’s 2016 Hughes v. Talen decision, which found that Maryland’s contract for differences with a generator could distort price signals in PJM.

Konschnik said the zero-emission credit cases in Illinois and New York are interesting because “in those two states alone, the state itself steps in and actually runs the [renewable energy credit] programs and now the ZEC programs, so there is this funny exception to the dormant Commerce Clause if the state itself is a market participant.

“So, if a state is building a public property and decides to only hire union workers from in-state, they can do that because they are acting as a purchaser or purveyor of goods rather than a regulator,” Konschnik said. “So, Illinois and New York may prevail, as they have so far in the lower courts.” (See 2nd Circuit Hears New York ZEC Appeal.)

Sen. King Calls for ‘Offensive’ on Cyberthreats

Speaking to NECPUC via video from D.C., U.S. Sen. Angus King (I-Maine) told regulators that the federal government needs to develop an “offensive response” to attacks on the grid and other critical infrastructure.

“I’m deeply concerned about the vulnerability of the grid to cyberattack either by malicious individuals, or more particularly, by international adversaries,” said King, a member of the Intelligence and Energy and Natural Resources committees. “We are not going to defeat this threat simply by defensive measures. As I’ve heard in numerous hearings, one of the great problems here in Washington is that we have no cyber doctrine. We have no cyber strategy that involves a response — an offensive response. … People that are taking advantage of those vulnerabilities essentially now pay no price. We are only trying to patch and defend.

“I believe until we develop an effective deterrent — and this is a federal responsibility — that these attacks are going to keep coming, they’re going to escalate and they’re going to become more and more serious. We have to communicate to the world that there is a price to be paid for attacking America, whether its cyber or kinetic.”

King said he is seeking to build bipartisan support “to push the administration … to form some kind of rational response so that our adversaries know there will be a price to be paid if they’re going to attack our critical infrastructure.”

Along with Sen. Jim Risch (R-Idaho), King is sponsoring a bill to partner the National Laboratories with industry to develop ways to “simplify and isolate automated systems” to holes in software systems that could be exploited by hackers.

Powelson Chides Region on Pipelines

Powelson | © RTO Insider

FERC Commissioner Robert Powelson told regulators that New England’s pursuit of greenhouse gas reduction is being undermined by its aversion to adding natural gas pipelines.

“We have a lot of natural gas we’d like to share with you,” the former Pennsylvania regulator said. “During the recent bomb cyclone, this region, that’s very committed to GHG reductions, in order to keep the lights on … burned 2 million barrels of oil.”

Last year, he said, the U.S. put 763 miles of new gas pipeline into service, but only 20 miles of it, representing less than 3 Bcfd, were built in New England.

“That’s a problem,” Powelson said. “You can’t have it both ways in this conversation. The renewable portfolio standards are states’ rights, and you can … adopt those policies. But if you don’t want to deal with resource adequacy, that’s our problem. And we’re kind of hitting these little friction points that pretty soon we might as well just hand the keys over and go back to the integrated resource planning model.”

EVs and Psychology of Resistance

Matthew Stanberry, vice president of market development at Advanced Energy Economy, an organization of businesses promoting clean energy, said electric vehicles represent “a market that fuels vehicles differently than we have in the past and plugs into our electric system, so you have an increase in regulatory activity and examination across the country.”

Twelve states have set EV charging rates, and 13 states have opened proceedings for public feedback on the topic, he said.

Vermont Department of Public Service Commissioner June Tierney said regulators have to start thinking about what it means for every single American to be driving an EV: “Who bears the risk of bringing the supply to fuel those EVs? Who pays for the infrastructure? What do you do about the loss of [gasoline tax] revenues from the transportation fund?”

Michael Brown, manager of EV infrastructure for Nissan, said the key to EV adoption is lowering the total cost of ownership. “That includes not just the financial cost but also the customer experience, which in some ways, especially in the light-duty market, is almost the most important piece,” Brown said.

“We see in surveys that over 50% of people say they’re interested in buying an EV, and then 85% say they’re concerned about charging infrastructure not being there,” Brown said. “Just yesterday, one of our colleagues in the industry, a huge supporter, who really wanted to buy an EV, said ‘Well, it’s 100 miles to the place I go to take my vacation, and I can’t take the risk that I might not find a charging station.’”

Massachusetts Energy Secretary Matthew Beaton said regional coordination is important on an issue like EVs, which “doesn’t really know state boundaries,” to develop charging infrastructure efficiently and ease drivers’ range anxiety.

“We need to know that if we’re going from point A to point B, the infrastructure is there,” Beaton said. “That’s going to be an amazing thing and a switch that will get flipped in the psychology of the consumer … people just need to get over range anxiety.”

Choosing Technology

Arcate | © RTO Insider

PowerOptions CEO Cynthia Arcate said her organization, an energy-buying consortium for nonprofits and the public sector in Massachusetts, Connecticut and Rhode Island, has learned to be selective in the technology it uses.

“When we talk about all these nifty things that we’re going to be able to do with all this technology, you really have to think about and make sure that a) the market’s not going to deliver it anyway for free; and b) that you don’t pick the wrong technology, which a lot of these companies are doing on the data analytics side,” Arcate said.

PowerOptions’ more than 400 members range from large universities and hospitals to churches and YMCAs.

Four years ago, billing analytics was the hot new thing, with everyone eager to put sensors on their circuits and know exactly what’s going on, she said.

“We spent a lot of time and money working with big sophisticated institutions, and uniformly they came back and said ‘we’re not interested,’” Arcate said.

She said customers told her, “‘I’m sick of getting reports. I don’t need another report to read. Don’t send me a report unless you’re going to tell me what it says, what I’m supposed do with it. And then do it for me.’”

PowerOptions offers customers several ways to pay for their electricity or gas service, including a fixed all-in contract, fixed price with capacity pass-through, or “two products that let the customer get visibility into the wholesale energy market without becoming a member of” New England Power Pool.

Gas customers can also purchase a “layering portfolio” to hedge prices.

“I have spent nine years … trying to get customers to move off the fixed all-in,” Arcate said. “They listen to me very patiently. They say, ‘I understand what you’re saying, but I’m going to go with the fixed price.’ That’s what customers want. They want predictability, they want certainty, they want to fix their budget and forget about it.”

Capacity Prices Jump in Most of PJM

By Rory D. Sweeney and Rich Heidorn Jr.

Capacity prices increased sharply in most of PJM for delivery year 2021/22, with prices for the RTO rising to $140/MW-day from $76.53 last year, an increase of 83%.

The ComEd zone increased $7 to $195.55/MW-day, while Eastern MAAC dropped to $165.73 from $187.87 last year (-12%). The PSE&G zone, which cleared as part of EMAAC last year, rose to $204.29.

| PJM

The ATSI zone, which cleared along with the rest of the RTO last year, separated this year, jumping to $171.33. BGE, which was part of MAAC last year, separated at $200.30. MAAC cleared at $86.04 last year. (See Capacity Prices down in Most of PJM in 1st Year of 100% CP.)

The Base Residual Auction procured 163,627 MW for 2021/22, resulting in a 21.5% reserve margin. That was down from 165,109 MW last year and a reduction of almost 2 percentage points from last year’s 23.3% reserve margin. That was still substantially above PJM’s 15.8% reserve requirement. About 192,450 MW offered into the auction, an increase from 189,918 MW that offered in last year.

The RTO obtained 893 MW of capacity from new generation and 508 MW from uprates to existing or planned generation, a 50% drop from the new capacity acquired in the 2017 auction.

“We did see a decrease in offers from new capacity resources. That certainly was not unexpected given the trends we have seen in the last several years,” Stu Bresler, PJM’s senior vice president for operations and markets, said during a news conference Wednesday.

PJM said the higher prices in most locations reflected continued low energy market prices, which causes generators to make higher capacity offers; an increase in the net cost of new entry, reflecting depressed energy revenues; and a drop in cleared capacity and the number of new generators. Partially offsetting those factors was a lower reliability requirement reflecting lower demand forecasts.

The auction, the second under 100% Capacity Performance, also saw increases in cleared demand response, energy efficiency and renewable resources.

| PJM

DR cleared 11,126 MW, up 3,305 MW, while EE cleared 2,832 MW, a jump of 1,100 MW.

Wind cleared 1,417 MW, an increase of 529 MW. Solar cleared 570 MW, more than quadrupling from 125 MW last year.

Coal generators increased their share by 500 MW, while gas rose by 1,000 MW, including one new combined cycle plant.

Cleared imports totaled 4,052 MW, most from west of the RTO. Deducting 1,320 MW in exports resulted in a net import of 3,405 MW.

Nuclear Decline

Cleared nuclear generation totaled 19,900 MW, a drop of 7,400 MW.

“I don’t think that came as much of a surprise to the market,” Bresler said, noting he had seen estimates of an even higher drop. “We continue to see a good amount of diversity across the system.”

Exelon announced afterward that its Three Mile Island and Dresden nuclear plants, and all but a small portion of the Byron plant, failed to clear in the auction. The company’s Oyster Creek plant, which is set to retire by October 2018, did not offer in the auction.

Robbie Orvis of the clean energy consulting firm Energy Innovation said the trend wasn’t consistent across all zones.

“Not only did a substantial amount of nuclear not clear (a 7.4-GW decline from last year), but capacity prices in regions with a lot of nuclear didn’t necessarily improve much, if at all. In EMAAC, which has roughly 25% of PJM’s nuclear capacity, prices actually dropped by $22.14/MW-day,” he said. “In ComEd, which has about 32% of PJM’s nuclear capacity, prices only increased by $7.43/MW-day. The remaining regions with nuclear capacity saw healthy price increases ranging from $53.96/MW-day to $94.80/MW-day.

“It’s unclear how units might have changed their bidding behavior in response to state nuclear subsidy programs, but given the economic hardships for many nuclear plants in PJM, these results don’t point to any kind of dramatic change in market conditions,” he said.

Jennifer Chen of the Natural Resources Defense Council pointed to a theory that Exelon might have “sacrificed” some nuclear megawatts, effectively holding them out of the auction to maintain a higher price.

Exelon and the Nuclear Energy Institute said the results pointed to the need for changes in market rules to recognize nuclear plants’ contributions to greenhouse gas reductions and grid resilience.

The company said it was the fourth consecutive year that TMI failed to clear, and that the plant, which it has threatened to close in October 2019, has not been profitable for six years.

It said its Quad Cities plant cleared “as a result of” Illinois’ zero-emission credit program.

Dresden and Byron, which have capacity obligations through May 2021 and May 2022, respectively, are not in immediate risk of retirement, the company said.

NEI CEO Maria Korsnick said the results “demonstrate the economic pressures facing well-run nuclear plants” because of “distorted market forces.”

“Energy Secretary [Rick] Perry has been ringing the warning bell that fuel security and resilience are critical to energy security and national security. Only by bringing the capacity and energy markets into better balance will we be able to realize the benefits of a diverse energy supply,” she said.

Coal Increases

Although coal’s share of cleared capacity increased by 500 MW, Bresler said the auction rewarded only some coal units.

“We did see some fairly large plants that had cleared last year that did not clear this year. On the other hand, we saw … increased cleared capability on a lot of existing units. I think what that may speak to is improvements in efficiency at those plants that are making them more competitive. I think they’re real close right now, in some cases, [to] natural gas. Coal plants that have larger capabilities, that can operate efficiently, that have made the environmental upgrades that are necessary … hung in there this year,” Bresler said.

“What this auction showed is — quoting a former colleague of mine — the death of coal has been greatly exaggerated,” he added.

Orvis said the outcome “indicates that these units are doing all right in PJM, and it certainly pours some cold water on arguments in favor of providing subsidies for coal units.”

End to Seasonal Concerns?

DR offered into this year’s auction increased almost 21% to 11,887 MW, nearly 94% of which cleared. Of the 11,126 MW of DR that cleared, 96% cleared as annual CP and 452 MW cleared as summer-only resources that were aggregated with other products to meet CP’s requirement for year-round commitment.

“I was a little bit surprised by the magnitude of the increase in annual demand response that was willing to commit to the [year-round] Capacity Performance requirements in this auction,” Bresler said.

“There’s been a lot of concern expressed in some parts of the stakeholder community about limiting demand response and not allowing that summer-only capability. Frankly, between the increase in aggregation we saw here and the amount of annual that was willing to commit to those Capacity Performance requirements, I have to question whether we still have an issue there.”

In total, 715.5 MW of seasonal capacity resources cleared as part of aggregated packages, an 80% increase from the 398 MW of seasonal resources that cleared last year. This year’s total included 452.3 MW of summer DR, 209.3 MW of summer EE and 53.9 MW of summer intermittent resources, which were packaged with 715.5 MW of winter resources — mostly wind.

Chen and Orvis questioned whether the higher-than-necessary reserve margin made seasonal resources less concerned about potential CP penalties and willing to take the risk to cash in on the auction revenue.

“There’s a structural issue and maybe PJM has a point that there’s always innovation … but the issue is if you have a structural issue, there is the potential for even more seasonal resources to participate and at lower clearing prices,” Chen said.

Orvis speculated that resources might have had trouble aggregating and bid in less megawatts than they have available to leave headroom if a CP assessment occurs in the winter.

“PJM should be careful not to imply that these results mean seasonality is not an important factor, and should think carefully about why the resources participated in the way they did, and how create a more efficient and optimized market down the road,” he said.

Katherine Hamilton, executive director of the Advanced Energy Management Alliance, attributed the increase in DR to “the more reasonable amount of time that providers had to work with their customers in preparation for the new capacity market rules; to improvements in customer-sited technologies; and to investments customers have made in their back-up generators to be compliant with an EPA rule.”

“We have yet to determine the real potential of consumer load response capability, which is expanding significantly this year,” she added. “Consumer participation and choice are critical for managing cost and reliability.”

DR provider EnerNOC said it will collect more than $180 million in capacity payments from the auction.

Vistra Energy said it will receive $559 million in capacity revenue after clearing almost 9,800 MW at a weighted average clearing price of $156.47, including 2,450 MW in ComEd and 6,435 MW in the rest of RTO.

Revenues Still Down

The increase in capacity prices won’t fully make up for lower energy prices, which account for the “vast majority” of wholesale costs, Bresler said. Capacity prices are perhaps 20 to 30% of wholesale costs, while energy revenues make up between 60 and 70%, he said.

“The increase in capacity prices certainly does not outstrip … the reduction in energy prices, however there is a relationship between the two,” he said.

Chen said she was “surprised that the prices increased so much given the oversupply.”

Orvis said the near doubling of prices for most of the RTO is good for generators in general but agreed with Bresler that they don’t represent large increases.

“For a 1-GW nuclear plant running at a 90% capacity factor, a $63.47/MW-day capacity market price increase is roughly equivalent to a $3/MWh increase in the average energy market price. For a 1-GW coal plant running at a 45% capacity factor, it’s roughly equivalent to a $6/MWh increase,” he wrote in an email. “Those are pretty small in the grand scheme of things, especially for nuclear plants.”

He said the “healthy” reserve margin, even with the reduction in nuclear, was “more evidence that Trump administration claims that losing generation will cause a grid disaster are complete nonsense.”

Cost Containment Coming to PJM Transmission Bids

By Rory D. Sweeney

VALLEY FORGE, Pa. — PJM stakeholders resoundingly endorsed LS Power’s controversial proposal to bring cost-containment measures into the RTO’s transmission planning process following more than two hours of debate before the Markets and Reliability Committee on Thursday.

The proposal will require PJM to evaluate cost commitments — including construction costs, return on equity and capital structure — in its analysis of competitive bids for transmission construction.

The approval came after a last-ditch attempt to delay a vote fell short.

TOs, who have been fighting the proposal for months, overwhelmingly opposed the measure, but stakeholders were won over by the chance to inject more competition and transparency into the process.

“We stand for markets. We stand for competition. We believe this … expands competition even further into the PJM processes,” said LS Power’s Sharon Segner, one of the main sponsors of the endorsed proposal.

Amendments

Thursday’s standoff was set in motion at January’s MRC, when stakeholders voted to defer a vote on an earlier LS Power proposal.

While LS Power had been heavily involved in special sessions of the Planning Committee that focused on the issue, the company had not sponsored a full-fledged proposal through PJM’s stakeholder process. It instead focused on attempting to change the RTO’s less comprehensive proposal. On the night before that proposal was set for a vote at the January MRC, LS Power submitted an alternative motion that differentiated between cost estimates and cost commitments and required PJM to weigh guarantees in its evaluation of bids.

When PJM’s proposal failed, TOs scrambled to bury the alternative LS Power proposal, eventually succeeding in having its vote deferred until the May MRC meeting with more special sessions scheduled in the interim for stakeholders to work toward consensus.

As its dispute with the TOs escalated, LS Power found allies among state consumer advocates, who pushed PJM into developing evaluation templates to standardize the bid process. TOs continued to fight the LS Power initiative and rallied behind a new RTO proposal that incorporated the templates but limited consideration of cost commitments to construction costs. LS Power also incorporated PJM’s templates but maintained its wider analysis of all cost guarantees.

At the Planning Committee meeting earlier this month, stakeholders endorsed PJM’s newest proposal, along with a recommendation that the MRC remand the issue back to the PC for further discussion. An effort to strip LS Power’s proposal of being the first voting item on the issue ultimately failed. (See Cost Containment Proposal Survives; Headed to MRC.)

In a final special session, just days before the MRC, LS Power teamed with Erik Heinle of the D.C. Office of the People’s Counsel to add several “friendly amendments” to the proposal. The revisions removed consideration of operations and maintenance cost guarantees but pushed for additional transparency and instructed PJM to work with its Independent Market Monitor to develop “comparative frameworks” for analyzing cost commitments versus cost estimates.

One would focus on construction costs, while the other would analyze ROE and capital structure commitments. While the friendly amendments were motioned and endorsed, opponents complained the repeated revisions subverted the stakeholder process.

“Once again, we haven’t followed the full process to vet the alternative motion,” Exelon’s David Weaver said.

LS Power attorney Mike Engleman of D.C. firm Engleman Fallon stridently refuted that argument, calling it “absolutely not true.”

The PC’s recommendation to remand the issue received substantial discussion at the MRC on Thursday, but supporters of the LS Power proposal opposed the delay, saying they feared it might never return for a vote.

“We are asking for a vote on the LS Power proposal, and we are strongly opposed to this notion of remanding this back to the PC,” Segner said. “Maybe it will get a vote at the PC, and maybe it won’t be based on how [the remand proposal was] drafted.”

“I think we have very different philosophical views, and I think we do need to vote” on the proposal, Heinle said. “Some things we’re not going to solve in the [stakeholder] process.”

Weaver said forcing a vote “will give an impression that the [stakeholder] process was a waste of time.”

“We do feel like that it’s not intractable,” he said, noting that TOs endorsed the templates. “But we do feel strongly that we do need time to understand impacts … so we can make sure that all stakeholders’ interests in cost containment are brought forward.”

Susan Bruce, who represents the PJM Industrial Customers Coalition, expressed “grave misgivings” with deferring the vote again, saying she felt the stakeholder process had worked. The conversation during the meeting was “very reasonable … but I worry,” she said.

“I’ve seen the conversations at the PC. I’ve read the letter,” she said, referring to a letter send by TOs to the Board of Managers requesting it order the MRC to not vote on the proposal. “With that lens, it’s a tough thing to be asked to defer this again.”

Several stakeholders, including the Monitor, urged members to reject the remand, which received a 1.95 sector-weighted vote, far short of the 3.335 threshold necessary for approval.

Following the vote, PJM’s Steve Herling said the proposals share many aspects and that while he “obviously … would have preferred” the RTO’s proposal, he was confident LS Power’s proposal is feasible.

“We believe we can implement their proposal, so at the end of the day, we’ll implement whatever is approved,” he said. “We have concerns, but we believe we can implement it.”

TOs’ Letter to Board

The sides then argued the legality of the LS Power proposal. Just a day before the meeting, 10 PJM TOs sent the board a letter arguing the proposal would infringe on the TOs’ rights under the Consolidated Transmission Owners Agreement, the Tariff and Section 205 of the Federal Power Act.

Proponents of the proposal disagreed, saying it only created a framework for PJM to evaluate bids that include cost guarantees, and that it doesn’t require TOs to include such guarantees in their bids. Heinle described the proposal as a “three-legged stool”: transparency through the evaluation templates; cost caps on ROE and capital structure; and comparative analysis informed by the Monitor.

“If incumbent transmission owners don’t choose to make a cost guarantee they don’t have to, but if they do, this puts some parameters around it,” Engleman said.

“At the end of the day, PJM looks at all relevant factors — cost just being one of them — and decides which is the right one to move forward with,” Segner explained.

American Municipal Power offered another friendly amendment, which added several small clarifications and confirmed that “neither PJM, the designated entity [winning bidder] nor any stakeholders are waiving any of their respective FPA Section 205 or 206 rights through this process.” An additional clarification on whether agreements between PJM and the winning bidder, known as designated entity agreements, would be filed at FERC was removed after PJM noted legal concerns. The remaining amendments were approved by LS Power and the proposal’s other sponsors.

PJM’s board did not respond to the TOs’ letter before the LS Power proposal was brought to a vote, where it received 92 votes in favor versus 17 votes opposed, or 3.79, well above the 3.335 threshold needed for approval.

The RTO must now work with the Monitor to develop the comparative frameworks, the first of which on construction costs is expected to be introduced in September and endorsed at the MRC on Dec. 6. It would be effective for long-term transmission proposal submission window, which runs from November to March. The second framework comparing ROE and capital structures is expected by May 1, 2019, to be effective for all submission windows going forward.

Westar-Great Plains Merger Wins Final Approval

By Rich Heidorn Jr.

Kansas and Missouri regulators on Thursday approved Great Plains Energy’s merger with Westar Energy, the final hurdles in a stock-for-stock merger of equals with an equity value of about $15 billion.

Shareholders of Kansas-based Westar will own 52.5% of the combined company, with Missouri-based GPE, the parent of Kansas City Power & Light, controlling 47.5%.

The new company, to be called “Evergy,” will have about 964,000 Kansas and 611,000 Missouri customers. The new company’s board will initially be composed of an equal number of directors selected by Westar and GPE.

The Kansas Corporation Commission approved the deal Thursday afternoon after the Missouri Public Service Commission cleared it in the morning.

“We appreciate that regulators and shareholders recognize the value in combining the companies,” said GPE Chairman and CEO Terry Bassham, who will be president and CEO of Evergy. Initially, the company will continue to serve its customers as Westar and KCP&L.

The Kansas commission approved the merger based on a March 2018 settlement agreement among commission staff, the Citizens’ Utility Ratepayer Board, Sunflower Electric Power, Mid-Kansas Electric, the Kansas Power Pool, Midwest Energy and solar developer Brightergy (18-KCPE-095-MER).

Westar and KCP&L retail electric customers in Kansas will receive one-time bill credits of $30.5 million and annual credits of $11.5 million from 2019 through 2022. Following their 2018 rate cases, KCP&L and Westar will be subject to a five-year base rate moratorium assuming their authorized return on equity is at least 9.3%.

The Kansas commission imposed an additional requirement that the companies develop an integrated resource plan process to “ensure the merger maximizes the use of Kansas energy resources,” it said in a press release.

The new company will maintain headquarters in both Topeka, Kan., and Kansas City, Mo., with the Topeka headquarters guaranteed for at least 10 years. There will be no involuntary severances because of plant closings, and the company’s 5,000 employees will receive compensation and benefits at current levels for at least two years.

The Kansas commission approved the deal over the objections of Kansas Electric Cooperative, which said the settlement did not address all its concerns.

Earlier in the day, Missouri regulators approved the deal, which provides initial bill credits of $29 million for their retail ratepayers.

“The merger will create a stronger combined company, with more customers, more geographic diversification, no transaction debt to complete the merger, and the prospect for higher earnings growth rates than either GPE or Westar would be able to achieve on a stand-alone basis,” the Public Service Commission said in its order (EM-2018-0012).

Kansas regulators last year pushed back on GPE’s original plan to buy out Westar, forcing the companies to recast the transaction as a “merger of equals.”

“It’s been a circuitous route to get here,” the Topeka Capital-Journal quoted PSC Chairman Daniel Hall as saying. “We had to fight through the jurisdictional issues, then we had to dismiss the case when our sister jurisdiction ruled it was not in the public interest and start all over again with this one.”

FERC approved the merger on Feb. 28 (EC17-171). (See FERC Greenlights Great Plains-Westar Merger.)

The deal is expected to close in early June. The company expects to rebalance its capital structure by repurchasing about 60 million shares of its common stock over a two-year period.

Great Plains stock closed Thursday at $19.75/share, up 1%. Westar shares ended the day at $54.58, an increase of 0.66%.

Steering Committee Advances MISO Market Improvement Ideas

By Amanda Durish Cook

MISO’s Steering Committee this week submitted eight new possible market improvement ideas to the Market Subcommittee for stakeholder discussion.

During a May 23 conference call, Steering Committee Chair Tia Elliott said all new Market Roadmap ideas will receive more in-depth discussion at the subcommittee, which could assign them to other stakeholder committees. MISO will also hold a stakeholder workshop on June 7 to discuss the new ideas.

MISO Market Roadmap Steering Committee

Originated by the Independent Market Monitor and stakeholders, the suggestions include:

  • Creating financial incentives for members that provide frequency response service, as suggested by Indianapolis Power and Light.
  • Allowing dispatchable intermittent resources to provide regulation service, a suggestion Xcel Energy submitted with the support of several other market participants.
  • Evaluating the feasibility of implementing a day-ahead market on a 15-minute basis rather than on an hour-to-hour schedule under MISO’s market platform replacement project. Monitor David Patton claims that a more specific schedule would reduce make-whole payments.
  • Removing transmission charges from coordinated transmission service transactions with PJM, another Monitor suggestion. MISO currently applies transmission charges to these transactions when they are offered, not just when they are scheduled, and the Monitor said the charges discourage CTS offers and “undermine the potential for substantial savings.”
  • Expanding modeling to include equipment operating characteristics and constraints of other types of generation resources, much like MISO is improving modeling for combined cycle generators, as suggested by Ameren Missouri.
  • Requiring that the installed capacity of planning resources be guaranteed as deliverable through firm transmission service, as suggested by the Monitor.
  • Allowing load-modifying resources and emergency-only resources to receive Planning Resource Auction capacity credit “if they are expected to be reasonably available in an emergency,” according to the Monitor.
  • Creating a look-ahead dispatch tool for generators. DTE Energy said MISO’s current practice of publishing the next dispatch instructions on a five-minute basis “can lead to inefficiencies with generators who need to bring on or off equipment to meet this dispatch.” DTE said it has support from several other market participants on the idea.

MISO Senior Manager of Market Strategy Mia Adams said that, after the workshop, the RTO and stakeholders will begin to rank the ideas in order of importance to determine when — if at all — MISO will begin to propose market changes to address them.

The Steering Committee has the authority to veto Market Roadmap improvement ideas before they reach the Market Subcommittee if they do not fit the definition of market improvements — although it cannot discuss the merits of the ideas — but it has never exercised that power.

Environmental Group Sees More Ill. Renewables, Bailout Bids

By Amanda Durish Cook

Illinois is advancing toward a cleaner energy future thanks to two decades of policy and market developments, and new efforts could accelerate the trend, a Midwest environmental advocacy group said Thursday.

Speaking during a May 23 webinar on the evolution of Illinois’ energy market, Brad Klein, senior attorney for the Environmental Law and Policy Center, said last year’s Future Energy Jobs Act, coupled with increasingly competitive renewable generation prices, will continue to sway the state toward clean energy. The law set renewable and energy savings goals for utilities, created community solar programs and restructured the state’s renewable target process and $200 million annual budget.

The ELPC predicts that by 2020, the FEJA will boost Illinois’ solar capacity from 84 MW today to 2.8 GW by 2022, and also add 1.3 GW to its current 4.3-GW wind portfolio.

However, Klein said he predicted “growing pains and bottlenecks” in the interconnection process to get the projected amounts of solar generation online.

Klein said although he expects Illinois will be able to meet its minimum new build targets for renewable resources by about 2020, the state will probably need to continue building renewables to meet its 25% use target in the Commonwealth Edison and Ameren territories by 2025.

“We think we’re going to hit the minimum thresholds for new wind and solar build-out in the early 2020s … but we’re not on track yet to meet that 25% by 2025. We expect that this will be a long-term and sustainable effort over time,” Klein said.

He also forecasts more future bailout attempts by nuclear and coal generation operators, particularly Dynegy, which is now owned by Vistra Energy.

Klein said the FEJA favors energy efficiency, renewable energy and nuclear generation, and the final version of the law excluded draft provisions for coal bailouts, demand charges and support for microgrids. He also said FEJA notably lacked any provisions on EV and energy storage, markets he’d like to see developed in Illinois.

There are opportunities for Illinois to develop municipal aggregation programs, which are currently “stagnant,” he said. “I’m hoping we’ll see a new wave of aggregation.”

The Path to FEJA

Klein said the ELPC expects more renewable and decarbonization policies to take hold incrementally in Illinois, as other energy-related state policies have in the past.

“It seems to follow a pattern: Every 10 years or so, there’s major legislation,” he said.

He noted that Illinois began to restructure its market with 1997’s Illinois Electric Service Customer Choice and Rate Relief Law, which cut rates by up to 20% and froze them for 10 years while introducing retail competition in the state.

Klein said the state’s next wave of change came in response to the 2006 reverse power auction that saw residential prices jump 20 to 50% after the decade-long price caps expired. The auction sparked a public backlash against utilities and power marketers.

“It led to a political situation that created the next major piece of legislation,” he said, referring to the 2007 creation of the Illinois Power Agency, an independent state agency that procures power for utilities, and the state’s first renewable portfolio standard.

The 2007 RPS fell short of the state’s goals, and utilities became “increasingly hostile” to distributed resources, Klein said, leading to 2017’s FEJA.

The IPA said last year that Illinois’ first RPS, combined with retail choice, meant customers could toggle between utility service and alternative suppliers, “leading to budget and target uncertainties.” As a result of the FEJA, Illinois today uses a single RPS, rather than administering separate rules for customers using alternative suppliers.

Mass., R.I. Pick 1,200 MW in Offshore Wind Bids

By Michael Kuser

Massachusetts and Rhode Island on Wednesday awarded procurements for 1,200 MW of offshore wind energy from what will become the two largest offshore projects in the U.S.

ISO-NE Offshore Wind Vineyard Wind
| Vinyard Wind

Vineyard Wind, a partnership between Avangrid Renewables and Copenhagen Infrastructure Partners, won the contract to supply Massachusetts with 800 MW of offshore wind energy, while Rhode Island selected Deepwater Wind to build the 400-MW version of the company’s Revolution Wind proposal.

Financial details for the fixed-price bids have not been disclosed.

“With today’s landmark decisions, Massachusetts and Rhode Island are ready to pioneer large-scale offshore wind development that will light the way for our industry and nation,” American Wind Energy Association CEO Tom Kiernan said in a statement. “With world-class wind resources, infrastructure and offshore energy expertise, the U.S. is primed to scale up this industry and lead it.”

Also on Wednesday, New Jersey Gov. Phil Murphy signed legislation codifying his commitment to build 3,500 MW of offshore wind by 2030, surpassing New York’s target of 2,400 MW. (See related story, Gov. Signs NJ Nuke Subsidy, Renewables Bills.)

Fast Start

“Vineyard Wind is proud to be selected to lead the new Massachusetts offshore wind industry into the future,” company CEO Lars Thaaning Pedersen said Wednesday. “Today’s announcement reflects the strong commitment to clean energy by Gov. [Charlie] Baker and the Massachusetts legislature.”

The Vineyard project will lie about 15 miles south of Martha’s Vineyard and include a transmission component linking back to the ISO-NE grid.

The company plans to begin construction in 2019 and start operating the first 400-MW section of the project by 2021, with the second half slated for completion in 2022. It got a head start on its rivals in the solicitation by beginning state and federal permitting processes in December and submitting the project’s draft environmental impact statement with state regulators on May 1.

Vineyard has said its project would generate 3,600 jobs, including 1,500 coming with the start of onsite construction. The company has also promised the project will yield significant CO2 reductions, displacing 1.25 million metric tons per year upon full operation in 2022.

Massachusetts Sierra Club Director Emily Norton called Wednesday’s announcement “terrific news” but said it is only the beginning.

“With the cost of offshore wind falling precipitously, we can transition much more quickly to 100% clean energy than anyone thought possible, and there is no time to lose,” Norton said.

“This is such an important milestone. Rather than drilling for oil and gas off of the New England coast, we will find our energy future blowing in the wind,” U.S. Sen. Ed Markey (D) said on Twitter.

In December, three developers — Vineyard, Deepwater and Bay State Wind — submitted bids in the request for proposals (83C), which called for a minimum of 400 MW but said the state would consider bids of up to 800 MW if it determined that a larger proposal was both superior to other proposals and “likely to produce significantly more economic net benefits to ratepayers.”

All three developers purchased renewable energy leases off the coast from the U.S. Bureau of Ocean Energy Management.

Massachusetts’ 2016 Act to Promote Energy Diversity mandated the Department of Energy Resources and the state’s distribution utilities — Eversource Energy, National Grid and Unitil — to sign long-term contracts for 1,600 MW of offshore wind by June 30, 2027. All three utilities had a hand in the selection, and an independent evaluator monitored and assisted the bid evaluation process.

Transmission Backbone

Deepwater Wind’s 400-MW project will connect to land at the Brayton Point substation in Somerset, Mass., and the company partnered with National Grid Ventures to propose an offshore transmission “backbone” scalable to 1,600 MW that would be open to other wind developers. (See Offshore Wind Developers Ponder Tx Options.)

The Revolution project will firm its output through an agreement with the largest hydroelectric pumped storage facility in New England, the 1,200-MW Northfield Mountain station operated by FirstLight Power Resources.

The company’s bid said its grid-scale storage and expandable transmission system would “result in energy market savings of $75 million annually for Massachusetts ratepayers, without counting the benefits of economic development or emissions reductions.”

Deepwater developed the first offshore wind farm in the U.S., the 30-MW Block Island project in Rhode Island, which began commercial operation in December 2016.

“Rhode Island pioneered American offshore wind energy, and it’s only fitting that the Ocean State continues to be the vanguard of this growing industry,” said Deepwater Wind CEO Jeffrey Grybowski. “We applaud Gov. [Gina] Raimondo for her bold commitment to a clean energy future.”

NY Task Force Examines Carbon Pricing Impacts

By Amanda Durish Cook

New York’s adoption of a carbon charge will likely increase the state’s wholesale energy prices, decrease prices for zero-emission credits and boost energy revenues for new “Tier 1” renewable resources supported by renewable energy credits, industry stakeholders heard Monday.

NYISO is aiming for its carbon charge to be “reasonably transparent and predictable,” ISO staffer Nathaniel Gilbraith told a May 21 meeting of the Integrating Public Policy Task Force, which is examining the impact of carbon pricing on New York’s wholesale market. The charge should also “avoid distorting dispatch decisions away from grid power that can create emissions leakage,” he said.

Public Policy Task Force NYISO Carbon Pricing

The ISO earlier this month proposed to incorporate the carbon costs into its market by deducting a uniform carbon emissions charge from each energy supplier. (See NYISO Floats Carbon Pricing Straw Proposal.) Resources with zero point-of-production carbon emissions — including nuclear, conventional hydro, wind and solar generation — would not be assessed a carbon charge.

Existing Policy Interaction

A Brattle Group analysis, released at the meeting, shows that NYISO’s proposal would increase wholesale energy prices but decrease ZEC prices “on a dollar-for-dollar basis.”

Brattle also concluded the charge would increase energy revenues for new Tier 1 renewables (resources supported by RECs), thereby driving down REC prices on an equivalent basis, although it cautioned that the offset could be lower because RECs are solidified in contracts while the carbon charge is subject to revision. But the proposal would not reduce prices for fixed-price REC contracts already in place, the group said.

The report also speculated that the Regional Greenhouse Gas Initiative may already be causing a leakage of allowances and emissions to other states not under the mandatory program. To combat leaks from a future New York program, Brattle suggested the state impose border charges and reduce the number of allowances it offers.

NYISO staff acknowledged that potential changes to RGGI make it difficult to predict exactly how New York’s carbon pricing will interact with the program. A new RGGI cap is set to take effect in 2020, and New Jersey and Virginia are both contemplating joining the program.

Consumer Impacts

The impact of a carbon charge on consumers is even less clear at this point.

NYISO Manager of Economic Planning Timothy Duffy said the ISO is working with Brattle on a consumer impact analysis that will study 2020, 2025 and 2030 using a reference case scenario from its annual Congestion Assessment and Resource Integration Study. The study assumes the existence of 250 MW of offshore wind and attainment of New York’s Clean Energy Standard by 2030, and also incorporates the latest large-scale renewable procurements issued by the New York State Energy Research and Development Authority.

The ISO will also study impacts on locational-based marginal pricing and other metrics in 2030 using a model assuming 2,400 MW of offshore wind coming online by 2030, and another scenario in which the R.E. Ginna nuclear plant and Unit 1 of the Nine Mile Point Nuclear Station retire by 2029. The NYISO/Brattle study will use NYMEX futures and prices in the U.S. Energy Information Administration’s Annual Energy Outlook to project natural gas price estimates.

Duffy said more assumptions for the analysis will be presented in early June.

Weekly Reporting

NYISO is also considering requiring generators to self-report emissions data on a weekly basis for billing, with true-ups occurring against reported emissions in a trusted database, such as those maintained by EIA or EPA.

Gilbrath pointed out that the “vast majority” of New York’s fossil-fuel suppliers are already subject to emissions reporting through RGGI. NYISO’s 140 generators over 25 MW and 18 cogeneration plants are required to report under the program, leaving 114 generators representing 98 GWh of net generation in 2017 without existing reporting obligations.

NYISO’s carbon pricing would cover “burner tip” carbon emissions directly attributable to wholesale energy and ancillary services, including start-up times and no-load levels, GIlbraith said, but he asked stakeholders for other suggestions about how the ISO should manage emissions reporting.

Gilbrath said NYISO will not charge upstream carbon emissions, emissions associated with compressing natural gas for use in power plants or other greenhouse gasses, including methane and nitrous oxide. He said excluding those emissions would help keep carbon pricing predictable and gives suppliers certainty.

Indiana Court Favors Duke in Cost Recovery Suit

By Amanda Durish Cook

An Indiana appeals court ruled Monday that Duke Energy can recover from its ratepayers the cost of damages associated with not fulfilling the terms of a wind energy purchase agreement.

The court said it found sufficient evidence to let stand the Indiana Utility Regulatory Commission’s (IURC) original approval of the recovery plan (93A02-1710-EX-2468).

In 2006, Duke and Benton County Wind Farm in Indiana entered into a power purchase agreement for which the IURC authorized full cost recovery from Duke ratepayers. However, in 2013 Benton sued Duke in federal court over what it claimed was a breach of contract when Duke failed to purchase energy from the facility. Benton interpreted the agreement to mean that Duke was responsible for lost production costs in addition to the power Benton delivered.

IURC PPAs Duke Energy

The U.S. 7th Circuit Court of Appeals ruled that Duke was obligated under the PPA to “pay for power not taken,” and the parties settled for $29 million, with the IURC deciding last year that the money should be recovered from Duke’s ratepayers over a 12-month period.

The IURC “recognized that Duke would be incurring significant costs in connection with the PPA,” the U.S. appeals court found. “Consequently, in order to further the commission’s policy of encouraging the development of renewable resources, the commission authorized Duke to recover all of its PPA costs from ratepayers for the entire 20-year term.”

Two ratepayers, Michael Mullett and Patricia March, appealed the IURC’s decision, arguing that its order was “contrary to law because the damages are ‘liquidated’ and ‘hypothetical’ and amount to impermissible retroactive ratemaking.”

But state court Judge Cale J. Bradford on Monday said there was no caselaw to support the appellants’ claim that “purely hypothetical” liquidated damages prevent Duke from ratepayer recovery for the PPA.

The Indiana court also noted that the $29-million settlement “is no more than customers would have paid had a different offer been submitted to MISO from March 2013 through June 2017, and is less than what potentially could have been awarded has [sic] a settlement not been reached.”

Bradford also found no merit that the recovery would amount to retroactive ratemaking. “The fact that the damages arose from a past dispute regarding a contract interpretation does not automatically make the commission’s order contrary to law,” he wrote. He added that although the case was not a rate case, even rates “are subject to subsequent reconciliation after historical costs have become known.”

Bradford also noted that paying lost production costs under wind farm PPAs is consistent with past cases involving Indianapolis Power and Northern Indiana Public Service Co.
