CAISO RC Effort Gets FERC Go-ahead

By Robert Mullin

CAISO cleared a big hurdle in its nearly yearlong sprint to become the primary reliability coordinator (RC) in the Western Interconnection as FERC approved a set of Tariff revisions covering the ISO’s new services.

“Today we’ve got some good news from FERC in terms of our ability to move forward,” CAISO Regional Integration Director Phil Pettingill told a meeting of the ISO’s Board of Governors after the order was issued Wednesday.

Pettingill said the FERC order will allow the ISO to start signing binding agreements to provide RC services with two dozen entities across the Western Interconnection. About 72% of the region’s load is now poised to sign on with CAISO, compared with 12% for SPP. BC Hydro is proceeding with plans to stand up RC services for its own territory in British Columbia, representing about 7% of load in the area overseen by the Western Electricity Coordinating Council. (See CAISO RC Wins Most of the West.)

The Tariff revisons approved by FERC create a new section containing CAISO’s RC provisions while also providing a pro forma service agreement and designating a rate schedule to implement service charges (ER18-2366). The commission’s approval of the service agreement means CAISO can begin onboarding RC customers starting Thursday.

CAISO’s filing spelled out the functions applicable to an RC under NERC reliability standards, including providing outage coordination; performing operations planning analyses; conducting real-time assessments; monitoring and wide-area situational awareness; administering a system operating limit methodology; approving system restoration plans and facilitating system restoration drills; and issuing operating instructions to RC customers regarding their monitored facilities.

CAISO will also offer optional services such as hosted advanced network applications for a one-time charge of $35,000 to $70,000 (depending on the number of takers) and physical security reviews.

In approving CAISO’s RC provisions, FERC rejected protests by some market participants over the ISO’s proposal to assess volumetric service charges on generation-only balancing authorities.

The protesters, which include Avangrid, Calpine and Gridforce Energy Management, contended that the ISO’s charge, which will be based on annual net generation (NG) rather than net energy for load (NEL), deviates from commission precedent for allocating reliability-associated costs. They argue that an NG-based methodology is unjust and unreasonable because it double charges end users for energy produced in generation-only balancing areas. Peak Reliability currently charges such BAs based on NEL, which translates into minimum assessment rather than a volumetric charge.

“In effect, protesters argue that CAISO will assess a transaction that is sourced from a generation-only balancing authority reliability costs both for its exports from a generation-only balancing authority and its imports to a traditional balancing authority,” the commission noted.

The protesters further contended the NG methodology violates cost-causation principles because generation-only BAs require less RC service than BAs with load. They said CAISO had performed no analysis on the relative level of oversight costs for either type of BA.

But FERC sided with CAISO on the issue, saying neither the Federal Power Act nor commission precedent dictate a just and reasonable rate methodology for RC service. The commission also determined that CAISO’s proposed allocation methodology will not result in double-charging.

The commission also rejected the contention the ISO’s approach violates cost-causation principles, noting that none of the protesters argued that generation-only BAs do not require or benefit from RC services.

“Rather, protesters assert that CAISO has not justified charging them a rate that they assert will be significantly higher than the rate charged by Peak Reliability,” the commission wrote. “Moreover, protesters argue that the RC services required for generation-only balancing authorities are substantially less burdensome as compared to those of a traditional balancing authority with load. CAISO, however, specifically identifies core services that an RC provides and explains that traditional balancing authorities and generation-only balancing authorities all use the vast majority of these core services.”

While FERC’s decision is significant, CAISO’s RC effort is still subject to WECC and NERC certification next year. Still, CAISO is poised to lead the way in effort to fill the void being left by Peak.

Pettingill told Wednesday’s board meeting that the ISO had been holding roundtable meetings with SPP, the Alberta Electric System Operator, BC Hydro and Peak to coordinate the transition to a post-Peak West. When the question arose as to who will manage the Western system model, he said, roundtable participants decided it should be CAISO.

The ISO also intends to hold a series of public meetings to address concerns, either quarterly or “as many as needed,” he said.

FERC OKs CAISO Plan to Deal with CRR Shortfalls

By Hudson Sangree

FERC has accepted CAISO’s revised proposal to protect electricity ratepayers from funding shortfalls in the ISO’s congestion revenue rights market.

CRR holders will be paid for their entitlements “only to the extent the CAISO collects sufficient revenue through day-ahead market congestion revenues and other sources to fund those entitlements,” the commission said in its Nov. 9 decision (ER19-26).

“We agree with CAISO that the proposal reasonably distributes the burden resulting from congestion revenue insufficiency and will help improve the revenue insufficiency and auction revenue shortfall,” FERC said. “Rather than relying solely on LSEs to make whole CRR holders in the event those obligations are revenue insufficient, CAISO’s proposal distributes the burden to all CRR holders.”

CAISO filed its proposed revisions Oct. 1 after FERC rejected an earlier plan to eliminate full funding of CRRs and instead scale payouts to align with revenue collected through the day-ahead market and congestion charges. In rejecting the earlier plan, the commission objected to how the ISO would treat counterflow and prevailing-flow CRRs differently (ER18-2034). (See CAISO Modifies CRR Plan, Seeks Quick Approval.)

The ISO acknowledged that its revised proposal relies on “essentially the same methodology” found in its prior proposal, with one “important” modification: a provision to net CRRs with both prevailing-flow and counterflow CRRs within a holder’s portfolio before scaling the payment to that holder.

CAISO also noted in its revised filing that CRR revenue shortfalls have continued into this year, and it urged the commission to quickly approve the revised plan to relieve ratepayers from paying costs for fully funding CRRs in 2019. The ISO’s Department of Market Monitoring has estimated that the shortfalls — which are allocated based on power consumption — cost California ratepayers about $100 million a year.

In ruling for CAISO, the commission rejected protests by the Western Power Trading Forum, which argued that the ISO’s stakeholder process on the revisions had been rushed and that they did not fully address FERC’s concerns on symmetry.

The commission also found that CAISO’s plan would curtail a commonly used strategy to exploit market loopholes.

“CAISO’s constraint-specific approach … discourages strategies that attempt to exploit differences between the CRR model and the day-ahead market,” it said. “Under CAISO’s current CRR process, congestion revenue insufficiency and the auction revenue shortfall can be driven by market participants purchasing CRRs over constraints that appear to be nonbinding in the CRR auction but are actually binding in the day-ahead market.

“According to CAISO’s analysis, this practice has been a driver of both revenue insufficiency and the auction revenue shortfall. Under CAISO’s proposal here, if there is a substantial difference between the CRR model and the day-ahead market such that the payments due to CRR holders vastly outstrip the available congestion revenues, then payments to CRRs will be scaled, making the strategy potentially less viable.”

FERC: Order 845 Compliance Unaffected by Rehearing Bids

By Rich Heidorn Jr.

FERC clarified Tuesday that rehearing requests on its April 19 order revising its pro forma large generator interconnection procedures did not affect transmission operators’ compliance obligations spelled out in the order (RM17-8-002).

Order 845, which set new rules to increase the transparency and timeliness of the interconnection process, took effect July 23, 75 days after its publication in the Federal Register. (See FERC Order Seeks to Reduce Time, Uncertainty on Interconnections.)

The order required transmission providers to submit compliance filings adopting the rule’s requirements as revisions to their large generator interconnection procedures (LGIP) and large generator interconnection agreements (LGIA) within 90 days of the publication.

On June 18, however, the commission issued a procedural order giving itself more time to consider about 20 rehearing requests on the rulemaking. On Oct. 3, the Office of the Secretary issued a notice granting a motion by the Edison Electric Institute to delay the compliance filings until 90 days after the commission rules on rehearing.

The American Wind Energy Association challenged the secretary’s notice, arguing that extending the deadline for compliance filings was a departure from commission precedent that rehearing requests do not stay commission orders. AWEA said the extension notice effectively stays Order 845 “indefinitely until a rehearing request is issued.”

But the commission said the extension notice “does not change or stay Order No. 845’s effective date, but simply extends the date that compliance filings are due.”

Order 845 adopted all but four of 14 potential rule changes in the commission’s December 2016 Notice of Proposed Rulemaking revising the pro forma LGIP and LGIA. The rulemaking, which was prompted by AWEA’s complaint over backlogs in interconnection queues, applies to generators larger than 20 MW.

Pinnacle West Lauds Ariz. Vote in Q3 Earnings Call

By Hudson Sangree

Pinnacle West Capital is poised to move forward with its own clean energy plans after Arizona voters rejected Proposition 127, the company’s CEO said during a third-quarter earnings call.

The ballot measure, backed by California billionaire Tom Steyer, would have required the state’s power providers to generate at least half their annual sales of electricity from renewable resources by 2030.

Pinnacle and its subsidiary Arizona Public Service, the state’s largest utility, fought the measure. The opposing sides spent a combined total of more than $50 million in the race. In the end, state voters rejected Proposition 127 by roughly 70% to 30% of votes cast. (See High Failure Rate for Western Ballot Measures.)

“The residents of Arizona voted overwhelmingly to defeat Proposition 127, ensuring the energy policy in Arizona will continue to evolve in a thoughtful and constructive manner,” Pinnacle CEO Don Brandt told analysts on the Nov. 8 call. “With Proposition 127 behind us, we can now work with stakeholders to establish forward-thinking energy policies that move towards an increasingly clean energy mix.”

Those plans include taking advantage of Arizona’s ample sunlight for solar power, he said, and continuing to champion the carbon-free electricity produced by the Palo Verde Generating Station in the Arizona desert, the nation’s largest nuclear plant.

“Arizona is number three nationally in solar energy installed, and our APS energy mix is already 50% clean,” Brandt said. “We’re on the cutting-edge of advanced battery storage technology. Arizona is uniquely positioned to achieve a cleaner energy mix with our abundant solar resource, leadership in advanced technologies and Palo Verde generating station, the largest clean energy generator in the nation.”

The company reported third-quarter 2018 earnings of $315 million ($2.80/share), compared with 2017 Q3 earnings of $276 million ($2.46/share).

In a news release, the company said the increased earnings were driven largely by the second-hottest summer on record in Arizona and a corresponding increase in retail sales.

“The average high temperature for this year’s third quarter was 105.3 degrees — 1.6% higher than last year’s quarter and 1.2% greater than normal based on a rolling 10-year average. The resulting impact in the 2018 third quarter was that residential cooling degree-days (a measure of the effects of weather) were 13% higher than in the same 2017 period and 5.4% above 10-year historical averages,” the company said in its statement.

Regulators Examine MISO, SPP Seams Issues at NARUC

By Tom Kleckner

ORLANDO, Fla. — MISO, SPP and their stakeholders have been flummoxed in recent years by market coordination, interregional planning and other issues across the grid operators’ seam. Now, the regulators are stepping in.

On Sunday, state regulators from MISO’s Organization of MISO States and SPP’s Regional State Committee met with staff from both RTOs and other interested stakeholders on the sidelines of the annual meeting of the National Association of Regulatory Utility Commissioners.

Two of the more interested participants were FERC Commissioner Cheryl LaFleur and Iowa Utilities Board Member Nick Wagner, NARUC’s newly installed president.

“This is a terrific opportunity to spend time face to face, talking about these things, given the length and complexity of the seam between the two,” LaFleur said. “It’s a tremendous opportunity to do things better in both respective market operations, as well as transmission and reliability operations on the seam, all to the benefit of the customers.”

LaFleur praised the two committees and their engagement with their RTOs. “It’s only logical these would be the two groups best to engage and put your heads together on the issues between the seams,” she said.

Wagner, whose state falls within MISO, told RTO Insider he was looking out for Iowa consumers and wants to ensure inefficiencies on the seam “are not costing consumers more than they should be.”

“We’ve seen issues on other seams. It’s not a novel issue,” Wagner said, referring to the PJM-MISO seam.

Shining a Light

MISO and SPP have been unable to agree on a single interregional project, and their market-to-market (M2M) process has resulted in more than $51 million in payments from MISO to SPP since March 2015, compensation for overloaded transmission elements. In January and September of this year, extreme weather events created emergency situations on MISO’s side of the seam. (See 3-Degree Forecast Error Triggered MISO September Emergency.)

Missouri Public Service Commissioner Daniel Hall, who chaired the OMS-RSC liaison committee meeting, told MISO and SPP staff, “Anytime we can get the two of you working together, that’s a good thing.”

Hall represents the OMS on the committee along with Louisiana’s Lambert Boissiere, North Dakota’s Julie Fedorchak and Minnesota’s Matt Schuerger. Kansas’ Shari Feist Albrecht, South Dakota’s Kristie Fiegen, Arkansas’ Kim O’Guinn and Texas’ DeAnn Walker represent the RSC. Wagner is an ex officio member.

“There’s value in shining a light on these seams issues and ongoing efforts to address them,” Hall said. “This is an excellent forum where we can identify issues [and] work collaboratively with MISO and SPP and other stakeholders to find solutions and track the progress.”

“I know there’s a role for FERC,” LaFleur said. “I do think there is some comparability between what’s happening on the SPP-MISO seam and what happened between PJM and MISO 20 years ago. Though it’s a lovefest now, it was very contentious at one point.”

The liaison committee — “or task force, or whatever we’re calling ourselves,” Hall said — reviewed a draft white paper it had requested from MISO and SPP staff. Working with regulatory staffers, the grid operators were to identify barriers to more efficient seams operations and transmission planning, offering solutions whenever possible.

Calling the white paper a “foundational document,” Hall said he expects to request additional information from MISO and SPP and solicit stakeholder comments.

The white paper itself will eventually be made public, although the committee is uncertain how it will do so. Both the OMS and RSC have created web pages for the group.

Adam McKinnie, a Missouri PSC economist who works with both committees, framed the white paper as a means of better understanding the dynamics of issues on the seam. He said its strength was in discussing the history behind previous interregional planning efforts, improvements to the M2M process, contract path capacity sharing and flowgate allocation.

Citing the complexity involved, McKinnie said the white paper doesn’t address pancake rates, conditional generator interconnection agreements and the grid operators’ 2015 settlement agreement on MISO’s North-South flows. (See FERC OKs MISO-SPP Transmission Settlement.)

Smoke Signal

Asked whether the M2M payments are a symptom of inefficiency, McKinnie said, “These payments are definitely smoke. They are sending signals that there are issues in the area.”

The M2M process determines which party has exceeded its allowed usage of an overloaded transmission element. The grid operator over its allotment is required to find a solution that relieves the congestion.

“If MISO is paying SPP, it’s because it’s cheaper than a transmission solution,” McKinnie said.

The usage allotment is based on metrics that date back to 2004. Staff agreed the process needs to be updated, but the RTOs continue to negotiate how to revise the allotment.

The grid operators also face a 2020 renegotiation of their joint operating agreement, in place since 2004. The JOA has been amended “many times” since then, McKinnie said, including implementation of the M2M payments and a FERC Order 1000 compliance filing. The grid operators also have a memorandum of understanding that guides the M2M process.

Noting MISO and SPP take different positions on fundamental ideas and Tariff and contract interpretations, McKinnie told Hall he thinks the RTOs are “doing a decent job of being focused on the right issues.”

“There seems to be some talking past each other,” Schuerger pointed out.

“We have worked to close the gap,” said Melissa Seymour, MISO’s executive director of customer and state affairs for the Central region.

Seymour pointed to the “significant amount of time” MISO staff have spent with SPP in preventing another occurrence of the January event, when severe cold weather and generation shortfalls in MISO South led MISO to exceed its regional dispatch limit on transfers across SPP’s system between its northern and southern footprints.

When MISO was forced to declare a maximum generation alert in September, the grid operators agreed communications across the seams was improved.

“We’ve been meeting on a monthly, sometimes weekly, basis with SPP,” Seymour said. “I think camaraderie is better as a result of that September event.”

“They don’t do a good job of telling their story,” McKinnie said.

SPP Director of Regulatory Policy Sam Loudenslager agreed. “We don’t publicize the positive events like we probably could.”

Sempra Divesting Solar for LNG, Regulated Ventures

By Hudson Sangree

Sempra Energy is on track to sell its renewable energy assets and invest the funds elsewhere, including in liquefied natural gas projects, the company said in its third-quarter earnings call.

“LNG is a key component of Sempra’s vision of becoming North America’s premier energy infrastructure company,” Sempra said during its slide presentation accompanying the earnings call Nov. 7.

Sempra, headquartered in San Diego, reported third-quarter earnings of $274 million ($0.99/share), up from $57 million ($0.22/share) in the third quarter of 2017. The company’s Q3 2017 earnings were hobbled by the wildfire costs of its subsidiary San Diego Gas & Electric. (See SDG&E’s Wildfire Costs Undercut Sempra Profits.)

Sempra has been moving away from commodities and putting its money into infrastructure.

In September, the company announced it was selling its interest in 980 MW of resources — 11 solar assets across the Southwest, solar and battery storage development projects and a wind facility in Nebraska — to Consolidated Edison.

Sempra is also investing in transmission and distribution infrastructure in Texas.

In October, Sempra said its Oncor utility subsidiary would acquire transmission owner InfraREIT, while Sempra will buy a 50% stake in Sharyland Utilities. (See Sempra, Oncor Deals Target Texas Transmission.)

“Our agreement to sell our U.S. solar assets is important. We expect to utilize capital from our solar asset sales to significantly expand our regulated Texas utility platform through Oncor’s acquisition of InfraREIT and our acquisition of a 50-percent interest in Sharyland,” Martin said in a Q3 earnings news release.

“We also have made significant progress toward our goal of becoming a market leader in North American liquefied natural gas (LNG) exports, recently securing preliminary commercial agreements for development of several LNG export projects.”

Analyses Show Flat Emissions Under NY Carbon Price

By Michael Kuser

RENSSELAER, N.Y. — New York electricity market stakeholders on Friday reviewed three separate studies to evaluate the implications of a carbon charge in NYISO’s energy markets.

The reports by the Brattle Group, Daymark Energy Advisors and Resources for the Future (RFF) find similar reductions in systemwide carbon emissions from a carbon charge: less than 1 million metric tons, according to the ISO’s synthesis of the studies

Michael DeSocio, the ISO’s senior manager for market design, told the Integrating Public Policy Task Force (IPPTF) Nov. 9 that “all the analyses were generally supportive of each other.”

All three studies isolate the effects of a carbon charge by modeling both a “base case” without carbon pricing and a “change case” with carbon pricing, but they each differ in the years evaluated. The Brattle study evaluates effects in 2020, 2025 and 2030, while Daymark’s analysis evaluates 2021-2025, 2030 and 2035. The RFF analysis focuses solely on 2025. (See NY Details Carbon Charge on Wholesale Suppliers.)

Analytical Results

Daymark’s Marc Montalvo said that his group’s study found that “carbon emissions in New York are about flat. There’s not really a material change as a consequence of the introduction of the carbon charge.”

RFF’s Dan Shawhan said his group’s updated results show “a CO2 emissions reduction of 0.2 million tons in the simulated year, which is 2025, and that’s about 0.65%, so about two-thirds of a percentage point reduction in New York emissions. And I don’t disagree with the characterization that you could describe that as not a big change in emissions.”

Brattle’s Sam Newell agreed and said “a lot of what’s happening here is we’re comparing to a base case that already has in place the Clean Energy Standard and other mechanisms to reduce emissions.”

But both the RFF and Brattle studies say that a carbon pricing policy can also be expected to reduce emissions in ways not captured in the modeling.

The carbon charge is another way of accomplishing decarbonization with more dollars put toward a market-oriented approach, and less money relying on targeted programs, Newell said.

“In both cases there’s decarbonization, so it’s not a surprise that there’s not some major change in carbon with the introduction of this policy,” Newell said. “Directionally it’s going to be an improvement because it finances some low-cost forms of carbon abatement, and there are probably some long-term investment effects.”

All studies find higher statewide locational-based marginal prices resulting from a carbon charge, with increases most significant downstate. The Brattle analysis finds LBMPs would rise by less than the Daymark and RFF studies.

Differences in LBMP changes can be at least partly explained by differences in each study’s modeling of the market heat rate, and also in part by assumptions regarding the net social cost of carbon in each study, the ISO’s summary said.

The studies assume similar carbon charges through 2025, but the Daymark study finds LBMP impacts would increase from 2025 to 2035. In contrast, Brattle finds lower carbon charges in 2030 than 2025 because of assumed increases in the Regional Greenhous Gas Initiative price, resulting in carbon charges of $45.40/ton in 2030, compared with $57/ton in 2030 assumed by Daymark.

Brattle and RFF both find collected carbon revenues on the order of $1.5 billion per year; Daymark finds declining carbon revenues, falling from $1.4 billion in 2021 to $1 billion in 2035.

Stakeholder Requests

DeSocio presented an update on NYISO’s progress in meeting stakeholder requests for further analysis on certain points.

Analysis is under way on augmenting the Brattle analysis with 2022 results and considering the effects of carbon pricing on repowering and retention, and should be ready for discussion at the Nov. 26 task force meeting, he said.

The ISO also said it does not recommend following a stakeholder suggestion to lower the 2030 RGGI price estimate because such a move is not supported by analysis based on results provided to date, DeSocio said. As RGGI is adjusted downward both with and without carbon pricing, the other parts of the analysis approximately scale. Because the overall impact is near zero, the scaled impact is near zero.

To consider the consequences of no carbon pricing, including estimates of the costs of various buyer-side mitigation scenarios, and the consequences of NYISO’s AC transmission project in western New York, the ISO is still considering how it might structure such analyses and will update the IPPTF at its next meeting, he said.

Regarding the effects of a carbon charge on existing renewable energy credit contracts and future REC contracts, DeSocio said, “In our analysis to date, we are not suggesting that REC contracts go away. Certainly the price of a REC contract may go down because the carbon price is being realized and therefore the delta payment that a renewable resource is getting is less, but in the analysis so far, we haven’t shown that to go to zero.” (See NY Carbon Task Force Looks at REC, EAS Impacts.)

The Daymark study does not evaluate changes in REC and zero-emission credit prices stemming from a carbon charge, but it finds the following gross profit margin (revenue minus fuel costs) average increases: upstate nuclear plants 70%; upstate solar 48%; upstate wind 46%; downstate offshore wind 47%; and downstate solar 51%, according to the ISO synthesis.

The RFF analysis finds the carbon charge would reduce REC prices from $43/MWh to $24/MWh and would reduce ZEC prices from $14/MWh to $0/MWh in 2025.

The Brattle analysis finds the carbon charge would reduce ZEC prices from $25/MWh to $12/MWh in 2025, while REC prices would fall from $22/MWh to $3/MWh in 2020, $25/MWh to $7/MWh in 2025 and $28/MWh to $12/MWh in 2030.

The task force next meets on Nov. 26. It plans to announce a proposal to incorporate carbon pricing into the state’s wholesale market next month.

OGE Beats Expectations with Q3 Earnings

By Tom Kleckner

OGE Energy beat expectations last week, reporting third-quarter earnings of $205 million ($1.02/share), up from a year ago, when it earned $183 million ($0.92/share).

A Zacks Investment Research survey of analysts had projected earnings of 96 cents/share.

“Good companies grow, and that is clearly what we are doing,” CEO Sean Trauschke said during a Nov. 8 conference call with analysts.

OGE’s regulated utility, Oklahoma Gas & Electric, contributed 92 cents/share during the quarter, thanks to new rates in Oklahoma, favorable weather and increased customer demand.

The Oklahoma City company also received earnings of 14 cents/share from Enable Midstream Partners, a gas-gathering and processing joint venture with Texas utility CenterPoint Energy.

Enable said Nov. 7 that it processed record amounts of natural gas during the third quarter. OGE holds a 25.7% limited-partnership interest and a 50% management interest in Enable, while CenterPoint owns a 54.1% share.

OGE increased and narrowed its year-end guidance to $1.59 to $1.61/share, up from $1.43 to 1.53/share.

OGE shares finished the week at $38.08/share, up almost 16% since the beginning of the year.

CenterPoint Earnings Drop 4 Cents

CenterPoint reported third-quarter earnings on Nov. 7 of $153 million ($0.35/share), a drop from a year earlier, when it earned $169 million ($0.39/share).

Revenues totaled $2.2 billion, up from $2.1 billion a year ago, thanks to increased rates and a growing customer base.

CEO Scott Prochazka told analysts during a conference call that the Houston-based company in October completed the equity and fixed rate debt components of the financing for its $6 billion acquisition of Indiana utility Vectren. Prochazka said the acquisition is still expected to close in the first quarter of 2019 and has targets in place “that are in line” with an $50 million to $100 million in pretax earnings by 2020.

CenterPoint’s share price lost 51 cents following the earnings announcement, finishing the week at $28.16.

New England Talks Energy Security, Public Policy

By Michael Kuser

MARLBOUROUGH, Mass. — Can New England balance reliability, economics and public policy in a fast-changing energy world? How will the region better prepare itself to handle winter cold snaps than in the past?

These and other questions arose at the Northeast Energy and Commerce Association’s 17th Power Markets Conference on Nov. 8. Here are highlights of what we heard.

Internalize, Don’t Politicize

Ashley Brown, executive director of Harvard University’s Electricity Policy Group, said, “My fear today is that we’re moving back to a battle between various special interest groups and further politicizing the sector.”

Resource selection based on economics, reliability and social benefits has given way to state subsidies and mandates that often work against public policy environmental goals, with uneconomic resources chasing bailouts instead of focusing on how to become more efficient, he said.

“Part of the problem … is that we have simply failed to internalize social considerations in economics,” Brown said. “The lack of a carbon policy in the U.S. is not only intellectually bankrupt, but it does in fact penalize emissions-free resources.”

Energy Security Banking

Mark Karl | © RTO Insider

Mark Karl, ISO-NE vice president for market development, said the region is moving into an era in which more resources have less fuel security. The grid operator is concerned the situation will get worse.

Fuel logistics become an issue in winter, whether because of natural gas pipeline constraints, limited dual-fuel storage or reduced ability to deliver oil by truck, he said. The significant retirement of large non-gas-fired generation is an important factor, as is the type of oil used.

“For example, some generators are burning No. 6 oil, which is basically almost asphalt, so in the wintertime, when that stuff gets cold, it gets pretty difficult to pump and move,” Karl said.

The retirement of two nuclear plants and the Brayton Point coal plant in recent years might be good for the environment, but collectively it presents a challenge for reliability, he said.

Karl said ISO-NE is looking to create a new reserve service referred to as “the energy inventory reserve constraint.”

“We’re proposing to incorporate into the real-time market an additional constraint that looks at the ability to provide energy storage or an energy bank,” he said. “I want to be careful here because it’s easy to think about this from the standpoint of conventional generator fuel, but this will apply to any sort of resource that has the ability to maintain essentially a reserve bank of energy that can be converted into electricity when needed.”

The idea is to optimize the use of limited energy over more extended periods compared with how markets are currently designed to optimize energy over the course of an operating day, he said.

Outside the marketplace, operators also worry about the next day and the days that follow, and sometimes order an oil-burning unit offline for a weekend anticipating the need to provide reserves come Monday, “so that’s an out-of-market action that does cause distortions in the marketplace,” Karl said.

Market Reaction

Brett Kruse | © RTO Insider

Brett Kruse, vice president of market design at Calpine, said ISO-NE could use a six- or seven-day-ahead market to effectively manage storage in a way that avoids having to take out-of-the-market actions.

The proposal could help the RTO manage how it deploys plants day to day and provide an insurance policy to keep a certain amount of storage in the system, he said.

“There are a lot of questions about that and how it would be priced, but it’s conceptually a pretty good idea,” Kruse said.

But he also had some reservations about the plan. “Looking at the way they’re presenting it now, where it’s a voluntary forward market, and won’t have any mitigation, which is a key aspect to go with that, we think it has some potential, although it’s hard to see how a lot of load will come into that,” he said.

David Cavanaugh, vice president of regulatory and market affairs for Energy New England, an energy services firm, said the RTO’s thinking at first glance seems robust, as its design extends beyond the winter period into a period where the bulk power system has more renewables and, perhaps, storage resources.

“I’m not sure the sophistication of this model gets us there … but we can be informed by other interim efforts such as the opportunity cost model set for use this winter,” Cavanaugh said. “I think the design is well thought out … just have some concerns when I look at the multi-day-ahead market, its voluntary participation,” in terms of maintaining adequate fuel stocks.

Abigail Krich, president of Boreas Renewables, said she sees a market design that, “even though it was triggered by fossil fuel issues, could work with that transition to a clean energy system that relies on intermittent generation. It looks like something that makes sure we have a dispatchable store of available energy in reserve.”

“I question whether we need all of these pieces in the proposal or whether we might just use some of them,” Krich said.

Public Policies

Discussing the race for renewables at the state level, Peter Fuller of Autumn Lane Energy Consulting said the tension in these markets is understandable. While consumers have benefited greatly from the markets, and investors and market participants have an expectation that everyone in the market will play by the same set of rules, states pursuing policy objectives don’t necessarily feel bound by those rules. In addition, the states have not been able, individually or collectively, to identify exactly what they want in a way that an RTO can create a market for it, he said.

Rather, states want to maintain control of resource decisions as policy objectives continue to evolve over time. “As much as anything they want to control that,” Fuller said. “If I’m a governor or legislator thinking how I want to transform the energy system in my state, my first instinct is not to send somebody to [the New England Power Pool] or to PJM to offer proposals, to come up with a matrix or a set of market rules and see how that plays out.” States are more likely to take direct action that then can cause dislocations in the markets.

Day Pitney attorney Sebastian Lombardi, who serves as counsel to NEPOOL, said that overlaying all the fuel security and grid resilience efforts is the need for regions to continue to engage in efforts to help bridge the divide between evolving state and federal policies and the market.

“From a state policy perspective, the competitive markets are not always achieving what they’d like the markets to achieve,” Lombardi said.

Darlene Phillips, senior director for strategic policy and external affairs at PJM, explained the RTO’s proposed revamp of its capacity market.

The Extended Resource Carve-out proposal would allow specific, state-subsidized resources to opt out of the capacity market and PJM to adjust market clearing prices as if the resources were still in it. (See related story, PJM Stakeholders Hold Their Lines in Capacity Battle.)

“If you don’t want your subsidized resources to get a minimum offer for price and go into the market, we will allow you to take those resources out of the market,” she said. “One of the things that FERC did not like about our original approach is that we actually paid those resources a payment.”

When it comes to existing renewable resources, PJM’s minimum offer price rule would have very little impact because the price would be zero, she said. The RTO applies a 20-MW threshold to renewables for the MOPR, which most of them don’t meet, though that situation might change with large-scale offshore wind coming along.

NERC to Try Again on Inverter Rules

By Rich Heidorn Jr.

ATLANTA — NERC stakeholders are expected to consider a new standard authorization request (SAR) to address inverter-based resources after the Standards Committee rejected two SARs proposed by CAISO in September, officials said last week.

CAISO submitted the SARs in May, saying it had recorded at least 14 occasions since August 2016 when inverter-based solar generation incorrectly tripped or ceased to operate during the routine high-speed clearing of short circuits on bulk electric system (BES) transmission. NERC has issued several reports and alerts following the two most serious incidents: the August 2016 Blue Cut wildfire, when 1,200 MW of solar disconnected; and the October 2017 Canyon 2 fire, which resulted in the loss of more than 900 MW.

The ISO proposed incorporating performance requirements for inverter-based resources connected to the BES in a revised NERC standard PRC-024, or developing a new standard for such resources and clarifying that PRC-024 applies only to synchronous generation.

At its Sept. 13 meeting, however, the Standards Committee rejected both SARs by a 12-5 vote on a motion by Dominion Energy’s Sean Bodkin, who noted the Institute of Electrical and Electronics Engineers (IEEE) is addressing the issues in Standard 1547-2018.

NERC is working with IEEE on the standards for inverter settings and developing instructions on compliance monitoring and enforcement activities related to the issue, James Merlo, NERC vice president of reliability risk management, told the Member Representatives Committee (MRC) at its quarterly meeting Nov. 6.

FERC Commissioner Cheryl LaFleur, who attended the MRC and Board of Trustees meetings, said she was concerned about the rejection of the SARs, saying “nothing clarifies the mind like an enforceable standard.” She said it was better for NERC and its stakeholders to design standards rather than respond to directives from FERC.

NERC CEO Jim Robb said he was disappointed that the two SARs “met with such headwinds at the Standards Committee.”

“I think we need to get over the notion that any standard creates peril and get to the point where standards create certainty,” he said. “And I think, particularly, in the case of these inverter resources, that’s a very, very important thing for us to do. … These resources are not going away. They’re already at scale in the West, and they will [soon] be at scale … in many parts of the country.”

Merlo said the Operating and Planning committees and the Inverter-Based Resource Performance Task Force will seek a new SAR to modify PRC-024 that will build on a white paper to be released in about two weeks identifying gaps between current standards and what’s needed by grid operators. “The expectation is the Standards Committee would take that up in December,” Merlo said.

“I’m optimistic that that will accomplish much of what we wanted to accomplish through the original two SARs,” Robb said.

The work may not stop with revisions to PRC-024, said Howard Gugel, NERC senior director of engineering and standards. “Then that task force is also going to go forward to say, ‘given that this is a brave new world and we have these resources, is there another standard that we should write that says how they should actually operate?’” he said in an interview. “And it’s not just limited to solar. … [idle EVs injecting energy into the grid are] an inverter resource also.”

NERC has already asked solar generators to modify their inverter settings to ensure voltage excursions don’t result in momentary cessation (MC) — when they stop injecting current into the grid. For inverters that cannot use another ride-through mode, NERC asked that MC settings be reduced to the lowest voltage value possible and that the recovery delay be reduced to one to three electrical cycles.

In arguing for the SARs, CAISO’s Keith E. Casey, vice president of market and infrastructure development, noted that NERC guidelines are not enforceable.

“Due to a lack of any standard addressing the minimum performance of inverter-based generation connected to the BES, original equipment manufacturers often apply standards for resources connected to the distribution system to BES resources,” Casey wrote.

NERC reported that most of the lost solar generation in the Blue Cut fire resulted when inverters incorrectly perceived a low frequency condition and tripped, not returning to service for five minutes or longer. “Five minutes may make sense on a rooftop, but five minutes is an eternity on the bulk electric system,” Merlo said.

NERC, which originally surveyed 13,543 MW of solar PV as potentially using momentary cessation, now believes all but about 1,952 MW do not use it or can overcome it with modified settings. (The survey covered only utility-scale solar generators at or above 75 MW, the threshold for generators that must register with NERC.)

“We understand a lot more than we did when we first saw the event just 18 months” ago, Merlo said.
