Appellate Court Rejects Challenge to FERC Funding

By Rich Heidorn Jr.

The D.C. Circuit Court of Appeals on Tuesday rejected environmentalists’ claim that FERC is incented to award pipeline certificates because it collects its operating expenses from regulated parties.

Upholding a lower court ruling, the D.C. Circuit also rejected the Delaware Riverkeeper Network’s challenge to FERC’s use of tolling orders to meet its statutory deadlines for acting on rehearing applications (17-5084).

The case arose from PennEast Pipeline’s 2015 application with the commission to build a 114-mile natural gas pipeline through Pennsylvania and New Jersey. Riverkeeper, which works to protect the Delaware River and its tributaries, intervened in opposition.

In 2016, while FERC was still reviewing the application, the group filed a complaint in U.S. District Court alleging that the commission’s funding structure creates structural bias in violation of the Due Process Clause of the Fifth Amendment. Riverkeeper also said the commission’s use of tolling orders to satisfy its 30-day deadline for acting on rehearing applications violates its members’ due process rights.

FERC’s Funding Mechanism

Although it receives an annual Congressional appropriation, FERC is required to recover its costs from regulated industries. Riverkeeper said the structure creates improper incentives for FERC to approve more pipelines so that it could seek larger appropriations from Congress.

The district court dismissed the case for failure to state a claim, agreeing with FERC and PennEast that Riverkeeper had failed to identify any liberty or property interest protected by the Due Process Clause.

The D.C. Circuit agreed, citing the Supreme Court’s 1928 Dugan v. Ohio ruling, which concerned a mayor who served a judicial function as one of five members of a city commission. Although the mayor’s salary came from the same general fund in which fines were deposited, the court said the salary was “not dependent on whether [the mayor] convicts in any case or not.”

As in Dugan, the appellate court ruled, “the adjudicator does not control the funds collected,” because FERC’s fees and charges are “‘credited to the general fund of the Treasury,’ not placed into its own coffers. Moreover, the commission’s budget, like the mayor’s salary in Dugan, is fixed by a distinct legislative body.”

“Regardless of how many pipelines FERC may approve, it ‘shall’ charge, for each year, a total amount ‘equal to all of the costs incurred by the commission in that fiscal year,’” the court said.

Due Process Standing

The Due Process Clause forbids the federal government from depriving a person of “life, liberty or property without due process of law.”

Riverkeeper based its due process claim on the 1971 Environmental Rights Amendment to the Pennsylvania Constitution, which guarantees its citizens “a right to clean air, pure water and to the preservation of the natural, scenic, historic and esthetic values of the environment.”

But the court said the amendment “protects not private property rights, but public goods,” and therefore is “too vague and indeterminate to create a federally cognizable property interest.”

In addition, the court said, “the rights created by the amendment bind only state and local government, not the federal government. … For all of these reasons, we conclude that the Environmental Rights Amendment does not create federally protected liberty or property interests, much less ones that FERC could infringe.”

Tolling Orders

The court also rejected Riverkeeper’s challenges to the commission’s use of tolling orders, which grant rehearing for the limited purpose of giving the commission more time to consider such challenges. Riverkeeper complained that the process frustrates judicial review in violation of the Due Process Clause because FERC routinely allows construction to proceed while the rehearings are pending.

“Regardless of whether any protected liberty or property interests are implicated, the commission is not a structurally biased adjudicator, and its use of tolling orders is not facially unconstitutional,” the court said. “We have long held that FERC’s use of tolling orders is permissible under the Natural Gas Act, which requires only that the commission ‘act upon’ a rehearing request within 30 days, not that it finally dispose of it.”

New York Looks at Carbon Price Impact on LBMPs

By Michael Kuser

RENSSELAER, N.Y. — NYISO on Monday presented stakeholders details on how a carbon charge would affect locational-based marginal prices (LBMPs) and imports and exports.

The ISO’s market software will not automatically calculate a carbon component of LBMPs because the carbon charge will be included with fuel and other relevant costs when bid into the current structure. Instead, the ISO envisions calculating an after-the-fact estimate of the LBMP carbon impact, said Ethan Avallone, senior market design specialist.

NYISO will report the estimated LBMP carbon impact for each of its 11 load zones, as well as for each external interface proxy bus.

“What information exactly we would use to make these calculations remains to be seen,” Avallone said at a July 9 meeting of New York’s Integrating Public Policy Task Force (IPPTF), the group charged with developing ways to incorporate the cost of CO2 emissions into wholesale energy markets.

“I think we would tie the emission rate to reference levels for the generation resources, so it would be close to the actual,” Avallone said. “But that’s why we say estimates, because it could differ depending on the mix of the fuel, etc.”

He added, “We’re considering whether the estimated LBMP carbon impact could be calculated and posted at a time granularity consistent with today’s LBMPs or if a different frequency would be more appropriate.”

IPPTF Chair Nicole Bouchez, NYISO’s principal economist, said the stability of the emission rates will determine how well the ISO can predict them and the consequences of estimates versus using a detailed cost breakdown.

Marginal Emission Rates

Several complications prevent NYISO from capturing the exact LBMP carbon impact, including the difficulty in identifying the marginal units because of product trade-offs (energy, spin, regulation), and time interval trade-offs involved in the ISO’s look-ahead for the next megawatt of supply, Avallone said.

“To me the big concern is that when you rank the marginal units in terms of costs, break up the costs for different units, that the CO2 component might vary or be rather erratic,” said Pallas LeeVanSchaick of Potomac Economics, the ISO’s Market Monitoring Unit. “First, that might be unnecessarily volatile, and secondly, it would gloss over the impacts of changes in commitment and other things that might not be marginal for one five-minute period, but they’re still marginal.”

Bouchez said, “Just to remind everyone, when we talk about marginal, we mean what unit would you be moving to serve the next megawatt of load, so the unit that is on a fixed schedule would not be the one that would be moved. … Pallas is also thinking a bit larger, which is do you actually change commitment to serve that next megawatt of load?”

Mark Reeder, representing the Alliance for Clean Energy New York (ACE NY), asked, “If a generator is in a zone, do you know how often the carbon on the margin on their bus would likely be quite different from what you get in terms of a zonal calculation?”

“The point to consider is that the generator at the bus that receives the carbon charge (impact in its bus LBMP) must pay the carbon charge for its emissions,” Avallone said.

Carbon Charge on External Transactions

NYISO staffer Nathaniel Gilbraith summarized the ISO’s proposal to rely on a “status quo” carbon pricing approach (referred to as Option 1) that would not consider the specific carbon content in energy trades from out of state. A second option under consideration would evaluate marginal emissions rates from out-of-state imports. (See NYISO Floats Carbon Pricing Straw Proposal.)

The ISO’s first consideration “was to avoid distorting import and export incentives, so that the goal here was to avoid creating a seam at the border where certain resources were compensated differently than others, which would result in a reshuffling of resources or fundamentally change import-export engineering,” Gilbraith said.

Representing New York City, Couch White attorney Kevin Lang said, “If what we’re trying to do is lower carbon emissions, then I’m not sure what the concern is about incentivizing more carbon-free imports into New York. In other words, we should be trying to create a level playing field for imports, just like what we’re doing in-state, where we’re trying to incentivize renewable resources.

“By trying to avoid the carbon character of imports and exports, you’re really creating an unlevel playing field, when what we are really trying to do is create a fundamentally competitive market with anyone to be able to compete on an equal basis.”

“I’d rephrase it as we’re trying to draw a specific border, and I think you would like to expand that border to include a broader set of resources that are potentially subject to the carbon pricing,” Gilbraith said.

Howard Fromer, director of market policy for PSEG Power New York, asked whether the complexity of calculating the marginal emission rate in neighboring areas is still the “driving reason” for the preference for this Option 1.

“There are several reasons why Option 1 is preferable and that’s one of the major ones,” Gilbraith responded.

Erin Hogan, representing the Department of State’s Utility Intervention Unit, said, “A generator that wants to export will have their carbon charge in the LBMP, but yet they’ll get a credit back at the border; so theoretically, if it’s equal, we could be exporting a significant amount of energy outside the state and … that would be the status quo.”

“That’s exactly right,” Gilbraith said. “If a generator is currently competitive with generation in an external control area and would like to export its power, let’s say in New England, it can do that today and they can profit on its relative efficiency compared to New England’s current system.”

“So then the drawback is not necessarily that it doesn’t incentivize cost-effective carbon abatement outside of New York, but that it also could limit the carbon abatement within New York,” Hogan said.

Warren Myers, DPS director of market and regulatory economics, said, “This has become focused on the technical aspect of the quantity of the emissions external to New York, and everybody’s just glossing over the fact that … it’s not just the quantity, it’s the value of carbon.

“In this proposal, New York state, not Pennsylvania, not Tennessee, not Massachusetts, would be saying how much each ton of carbon is worth,” he said. “To my mind, Option 1, for good or ill, minimizes the exporting of a New York state policy when it comes to interstate trade.”

Revised Charter

NYISO Senior Manager for Market Design Michael DeSocio presented a revised charter for the task force, which requires that all proposed analyses and their methodologies go through the ISO’s stakeholder process, starting at the Market Issues Working Group before going to the Business Issues Committee.

The task force next meets July 16 at NYISO headquarters to review draft recommendations for issue Tracks 2, 3 and 4 covering, respectively, wholesale energy market mechanics, policy mechanics and interaction with other state policies.

UPDATED: Exelon Bids $140M for FirstEnergy’s Retail Business

By Rich Heidorn Jr.

Exelon announced Tuesday it has signed an agreement to purchase the retail business of bankrupt FirstEnergy Solutions for $140 million in cash, an acquisition that would increase the number of customers for its Constellation unit by almost 50%.

The deal, which must be approved by the U.S. Bankruptcy Court for the Northern District of Ohio, would transfer FES’ retail electricity and wholesale load-serving contracts and other commodity contracts to Constellation.

Constellation currently serves about 2 million customers, including residential customers in 17 states and Washington D.C. | Constellation

In an 8-K filing, Exelon said it will close the deal in the fourth quarter if it is successful in a bankruptcy court-supervised auction. Either party can cancel the transaction if it is not complete by the end of the year.

FES filed for a Chapter 11 bankruptcy restructuring on March 31. (See FES Seeks Bankruptcy, DOE Emergency Order.) On Monday, FES filed a motion seeking approval for bidding procedures and scheduling an auction for Sept. 6, with bids due Aug. 23.

FES’ retail power business serves 900,000 commercial, industrial and residential customers in Michigan, Ohio, Pennsylvania, Illinois, Maryland and New Jersey.

“The purchase would leverage Constellation’s significant retail platform and is in line with our generation-to-load strategy, strengthening our position as the nation’s largest competitive energy supplier and bringing Constellation’s total customer base to more than 3 million residential and business customers across the continental United States,” Exelon said in a statement. “We would honor all existing retail customer contracts and look forward to offering newly acquired customers the same quality products and services that existing Constellation customers currently enjoy.”

FES said in a press release that it expects to receive a net of $280 million in cash from the transaction “subject to certain purchase price adjustments, including the return of cash collateral and collection of retained net working capital.”

“We believe this transaction is another important step in our restructuring plan,” said FES Chief Financial Officer Kevin Warvell. “If approved, we will work with Constellation to ensure the transition of customer accounts is seamless. During the sale process, our daily operations will continue as usual.”

FES hired Barclays Capital early last year in a bid to sell the assets but decided not to proceed after receiving initial proposals from eight suitors. The company said it abandoned the sale because the purchasers’ proposed terms “made it challenging” for the company to complete a deal outside of a bankruptcy proceeding.

Before entering bankruptcy in March, FES retained Lazard to handle an in-court divestiture. Lazard contacted 35 potential buyers, including “broadly focused financial investors, power- and energy-focused financial investors, strategic retail and power generation companies,” FES said.

The second effort yielded offers from six bidders in March, one of which was rejected because it did not include FES’ entire retail business. FES said it ultimately selected Exelon’s offer as the best, or “stalking horse,” bid.

Under the proposed auction procedures, a bidder challenging Exelon would need to offer an “initial topping bid” of $146.6 million, with subsequent bids in increments of at least $1 million. The auction will be canceled if no bids other than Exelon’s are received.

In a separate motion Monday, FES sought to file the unredacted sale agreement under seal to prevent it from disclosing the details of a mechanism that could adjust the purchase price and that allocated value by individual customer accounts. FES said disclosure of those details could reduce the ultimate purchase price.

Constellation serves residential customers in 17 states and D.C. after acquiring retail operations from Consolidated Edison in 2016 and Integrys Energy Group in 2014. (See Exelon’s Constellation to Buy Con Ed’s Retail Operation.)

FirstEnergy shares closed Tuesday at $35.39, up 0.2%. Exelon rose 0.76% to $42.17.

FERC Denies Cloverland PURPA Exemption

By Amanda Durish Cook

FERC on Monday denied Cloverland Electric Cooperative’s request for relief from its mandatory purchase obligation under the Public Utility Regulatory Policies Act (PURPA), citing the co-op’s lack of RTO membership as a primary reason (QM1811).

Cloverland, which serves customers in Michigan’s Upper Peninsula, filed in April to terminate its PURPA obligation to buy power from qualifying facilities (QFs) over 20 MW, arguing that, as a transmission-dependent utility that purchases transmission service from American Transmission Co. (ATC), QFs over 20 MW could not “safely interconnect” to the co-op’s distribution system “even with significant upgrades.”

Cloverland argued “the only practical way” for a QF over 20 MW to sell its input to the co-op would be to interconnect to ATC’s transmission system. It also contended that, although it doesn’t participate in MISO, ATC is a member of the RTO, where QFs have nondiscriminatory market access. The co-op said QFs within its service territory could utilize ATC’s transmission system to gain nondiscriminatory access, a prerequisite for utilities seeking relief from PURPA purchase obligations.

A utility can be exempted from its PURPA energy and capacity purchase obligations if it can demonstrate a need for relief and is a member of an RTO/ISO market.

But FERC said Cloverland could not use ATC’s MISO membership as a proxy for securing its own RTO/ISO membership.

“In essence, Cloverland, while not itself a MISO member, is seeking to claim the benefit of ATC’s MISO membership in requesting relief from the mandatory purchase obligation under PURPA … We are not persuaded to grant Cloverland’s application,” FERC said.

FERC determined that, because Cloverland is not a member of MISO, it is not entitled to relief from the purchase obligation despites its claim that nearby QFs nevertheless have access to MISO’s markets.

“We are not persuaded to change our position on the reach of PURPA … Membership in an RTO/ISO remains a requirement for claiming an exemption under PURPA … ” FERC said. “ … Accordingly, since Cloverland is not itself a member of MISO, it is not entitled to relief.”

How Long a Bridge for Natural Gas?

By Rich Heidorn Jr.

WASHINGTON — The 12,000 attendees at the World Gas Conference last month seemed unaware that the ground is shifting under their feet. Yet that is what’s happening, the Rocky Mountain Institute contends in a new analysis.

The clean energy think tank says that utilities, investors and regulators should be skeptical of any new investments in natural gas-fired generation because the combination of renewables and storage is already cheaper than combustion turbine peakers in some regions and will fall below the cost of combined cycle plants within a decade.

RMI’s analysis is the latest to sound warnings for gas. In March, IHS Markit published an analysis that found that batteries with access to cheap renewable power can be cheaper than CTs.

Greentech Media Research says storage will be competitive with gas peakers within four years and cheaper within 10 years. “I can’t see a reason why we should ever build a gas peaker again in the U.S. after, say, 2025,” Shayle Kann, a senior adviser to GTM Research and Wood Mackenzie, told GTM’s Energy Storage Summit last December. “If you think about how energy storage starts to take over the world, peaking is kind of your first big market.”

However, Bloomberg New Energy Finance does not see gas’ role as the “bridge” fuel between coal and renewables ending any time soon, instead forecasting an increased role for gas peakers for the next three decades.

At the World Gas Conference at the Walter E. Washington Convention Center, speakers on a panel on the role for gas in power generation also were more bullish.

With global power consumption expected to double by 2050, gas has a “great opportunity” to grow, said Shankari Srinivasan, vice president and managing director of global gas and EMEA power for IHS.

She acknowledged the growing competition from renewables and batteries and the impact energy efficiency can have on power demand growth. But in constructing future scenarios, IHS “found it very difficult to construct a case … where [global] gas-fired generation declines,” she said. “Renewables on their own are unlikely to be able to support this level of growth. In the U.S., I think we will continue to see gas taking a large share of power generation and remaining a fundamental part of the power generation mix.”

In contrast, Srinivasan said Europe may be seeing “the beginning of the end” of combined cycle gas turbine construction.

“I am, I think, being a little provocative. But it is possible to envisage new generation capacity as a mix of renewables and maybe only open cycle gas turbines,” she said.

The price of gas will be paramount in China and the rest of Asia, which will each account for one-third of global power demand growth through 2050.

“In Asia, development and growth of gas will depend on how competitive it is with coal … and the strength of clean air policies. … Gas as a bridge to a zero-carbon future may be skipped entirely — replaced by a gray-green world of coal and renewables in certain parts of the world.”

Another panelist, De la Rey Venter, Royal Dutch Shell’s executive vice president for integrated gas ventures, insisted that gas will remain essential to balancing the variability of renewables for at least a decade.

“There are those who say that ultimately batteries will eat gas for breakfast. We don’t quite subscribe to that logic,” he said. “There are many things that need to happen before batteries can play a meaningful role beyond short-term balancing of fluctuations in the system.”

In addition to reducing their cost and improving their performance, Venter said batteries need frequent access to low- or no-cost power for charging to be competitive.

Venter said the gas industry needs to “fight this notion that …. there’s this existential competition between gas and renewables.”

“Gas is the ultimate enabler of renewables,” he said. “If you really want to see a … widespread penetration of renewables, you need to have gas for the next decade or two.”

Stakes: Replacing Half of Thermal Capacity by 2030

Although there is disagreement over when gas will lose its appeal for power generation, there’s no doubt that the stakes are huge, both for the industry and consumers.

RMI notes that more than half of U.S. thermal generating capacity is more than 30 years old and expected to reach retirement age by 2030. It estimates that it would cost more than $500 billion to replace all retiring power plants with new natural gas-fired capacity (including $110 billion in investments already announced by utilities and independent power plant developers).

“This will lock in another $480 billion in fuel costs and 5 billion tons of CO2 emissions through 2030, and up to 16 billion tons through 2050,” RMI says. “The current rush to gas in the U.S. electricity system could lock in $1 trillion of costs through 2030.”

RMI sees a $350 billion (net present value) market opportunity through 2030 for renewables and distributed energy resources supplanting gas projects where cost effective. That would eliminate $370 billion of gas capital costs and operating expenses, a net savings of more than 2%, it said.

“This investment trajectory would unlock a market for renewables and DERs many times larger than today’s,” RMI said. It would also reduce carbon emissions and save consumers money — even excluding DERs’ value to the distribution system beyond peak load reduction or avoided fuel price risk or any emission costs.

Cheaper than Peakers, Nearing Parity with Combined Cycle

RMI’s analysis found that the clean energy portfolio — wind, solar and DERs, including batteries — was cheaper than two CT plants planned for serving peaks, beating one in the Mid-Atlantic by 60% and one in ERCOT by 47%.

In a comparison with CCGT power plants with higher capacity factors, RMI said the clean portfolio was 8% cheaper than a CCGT in California but 6% more costly than such a project in Florida, RMI said.

“Factoring in expected further cost reductions in distributed solar and/or a $7.50/ton price on CO2 emissions, all four cases show that an optimized clean energy portfolio is more cost-effective and lower in risk than the proposed gas plant,” the report said.

In addition to competing with proposed gas generation, clean energy portfolios will also undermine the profitability of existing plants within eight years, RMI says. In some areas, clean energy portfolios’ combined construction and operating costs — levelized cost of electricity — will be lower than CCGTs’ operating costs by 2026, assuming $5/MMBtu gas (translating to operating cost of $36/MWh). Assuming gas prices remain about $3/MMBtu ($23/MWh), the alternatives won’t be cheaper until about 2040 — still within the operating lives of plants being proposed now, RMI says.

$144 Billion Stranded?

“In other words, the same technological innovations and price declines in renewable energy that have already contributed to early coal plant retirement are now threatening to strand investments in natural gas,” the report says. “Thus, the $112 billion of gas-fired power plants currently proposed or under construction, along with $32 billion of proposed gas pipelines to serve these power plants, are already at risk of becoming stranded assets.”

With about 83% of announced gas projects proposed for restructured markets, independent power producers would bear most of the risk of competition from DERs and renewables.

The trends are also beginning to pinch IPPs’ suppliers. Bloomberg reported in June that Siemens is considering selling its gas turbine business. The company’s CFO told investors in March that the market for large gas turbines will fall to 100 units in 2018, 10% below the company’s previous projections.

Competitor General Electric also sees a “soft” market for gas turbines for several years. Two-thirds of its power capacity additions in 2017 were renewables. But in announcing a corporate restructuring in June, the company told investors, “Gas remains key to long-term energy mix.”

California, Arizona Leading the Transition

RMI cites as examples 11 alternatives to new thermal power plant investment now under consideration. Six of them are in California, where the abundance of solar and wind — and the state’s environmental goals — have made gas-fired generation an endangered species.

In February, the California Public Utilities Commission issued its first integrated resource plan. Intended to help the state meet its 2030 greenhouse gas reduction goals — a 50% reduction in electric sector GHG emissions from 2015 levels — the plan sees no new gas-fired capacity through 2030. Incremental generation needs are instead satisfied by utility-scale solar (73%), in-state wind (9%), battery storage (16.3%) and geothermal (1.7%).

CAISO has approved battery energy storage (BES) as a capacity resource if it can maintain its rated output for four consecutive hours over three consecutive days.

NRG Energy last October asked the California Energy Commission to suspend its review of the proposed 262-MW Puente plant in Oxnard after commissioners recommended rejecting the application. The turnabout came following criticism that the 2014 analysis that supported the gas addition did not reflect steep price declines since then for non-emitting alternative resources. (See NRG Signals Pull-out on Proposed Puente Plant.)

California regulators in January ordered Pacific Gas and Electric to solicit energy storage, renewables and load management options to replace three uneconomic Calpine gas peakers. On June 29, PG&E proposed to fill its need with four storage projects totaling 567 MW.

In March, PG&E solicited proposals to develop up to 45 MW of “clean energy” resources, including at least 10 MW of energy storage, to replace the aging 165-MW Dynegy Oakland jet fuel-fired power plant. It would be the first time PG&E used clean energy resources as an alternative to fossil fuels for transmission reliability. (See PG&E to Seek Storage, EE to Replace Dynegy Plant.)

Also in March, the Arizona Corporation Commission rejected Arizona Public Service’s plans to double its natural gas fleet over the next 15 years, instead ordering that utilities show that storage is not a cost-effective option before seeking approval of new natural gas units.

APS and Xcel Energy Colorado are among the utilities whose solicitations have produced renewable and storage bids at lower energy or capacity costs than thermal generation. Xcel received 87 bids for solar/storage projects at a median price of $36/MWh — compared with the $85/MWh levelized cost of electricity for an advanced CT, according to the Energy Information Administration.

To be sure, battery technologies will have to improve to be a solution in colder climates, where winter peaks can last for more than four hours.

Nevertheless, Xcel Energy CEO Ben Fowke told The Wall Street Journal earlier this year, “I could see in 10 to 15 years where you have 30% of what is traditionally a peaker market served by storage.”

Mark Dyson, RMI | Rocky Mountain Institute

Mark Dyson, one of the authors of the RMI study, discussed its findings in a webinar last week, citing evidence that investors agree with its conclusions.

Dyson cited the 7% one-day drop in GE’s share price in late May after CEO John Flannery told investors that the market for the company’s large gas turbines will remain weak through 2020. “The narrative was around the bad bet that it made in doubling down on new gas as a growth opportunity,” Dyson said.

“We see other investors looking at the PJM capacity market results and seeing how much uncleared gas there was that was in the queue. That’s kind of another hint that the market is cooling,” he added.

IHS also Bearish on Peakers

The results of RMI’s analysis were consistent with those published in March by IHS Associate Director Wade Shafer and senior analyst Sam Huntington.

The two compared a scenario in which California’s incremental resource adequacy needs from 2021 to 2030 were met entirely with CTs versus one using four-hour lithium-ion (Li-ion) BES.

They concluded that despite projected cost declines, the levelized fixed cost (capital and fixed operations and maintenance costs) of a four-hour Li-ion BES system will remain more expensive than a typical CT through 2030. But with inexpensive power for charging, they said, batteries would have a lower operational cost. “If the savings in systemwide production costs exceed the premium in fixed costs, BES systems would yield net benefits relative to CTs,” they said.

IHS’ analysis assumes that by 2030, more than half of California batteries will be linked to otherwise-curtailed solar PV, giving them access to low- and no-cost power.

If California met all its peaking capacity needs from 2021 to 2030 with BES instead of CTs, net present value benefits to the power sector would be about $16 million — essentially break-even given the size of the investments, the study found. “Savings also arise from the higher efficiency of the remaining thermal fleet — batteries smooth the variability in net load, resulting in fewer start-ups by peakers and allowing mid-merit plants to operate at lower heat rates,” they wrote.

Their conclusion: “California appears to be on the right track in terms of requiring batteries to cost-effectively manage the excess solar energy created by the [renewable portfolio standard]; however, IHS Markit has not evaluated the optimal year to fully transition from new gas-fired capacity to batteries.”

In an interview, Huntington said the RMI analysis appeared sound. He said he was somewhat surprised that RMI found not only peakers but CCGTs at risk. “A lot [of the RMI analysis] relied on energy efficiency and demand response, something we haven’t looked at as closely,” he said.

Dissenting Voices

In contrast, BNEF contends gas will remain vital through 2050.

Its 2018 New Energy Outlook report predicts coal and nuclear will “have almost disappeared from the electricity mix” by 2050, while renewables penetration will reach 55%. Supporting renewables, batteries will “grow in significance” beginning in 2030, it said.

BNEF projects PV module prices to continue dropping at the 28.5% “learning rate” of the last 40 years — meaning costs drop 28.5% for each doubling of deployed capacity.

Li-on battery pack prices will fall by almost two-thirds between 2017 and 2030, BNEF says, driven by the learning rate of a 27-fold increase in electric vehicle sales.

But while cheaper renewables and batteries will hurt most thermal power sources, BNEF sees an increased role for gas peakers.

“As thermal plants retire and variable renewables increase the variability on the supply side … peaking gas emerges as a critical technology to back up renewables during the extremes when wind and solar are at a minimum (sometimes this can be up to weeks at a time),” BNEF said. “We expect peaker gas to grow by almost a factor of four by 2050, as a cheaper, more nimble alternative to large-scale CCGT and coal-fired power plants running at low capacity factors.”

FERC Closes Book on Va. Tx Undergrounding Dispute

FERC last week ended a seven-year-old dispute over cost allocation for three Virginia Electric Power Co. transmission undergrounding projects when it accepted a compliance filing and denied related rehearing requests (ER18-318, EL10-49, et al.).

At issue was whether Old Dominion Electric Cooperative and North Carolina Electric Membership Corp. (NCEMC) should be required to pay the additional costs of undergrounding VEPCO’s Pleasant View, DuPont Fabros and Garrisonville projects.

VEPCO’s filing revised its tariff to remove, extending back to March 17, 2010, the incremental costs of undergrounding the projects, and instead charged those costs to wholesale transmission customers in Virginia, which had mandated the undergrounding. In response to a conditional protest by NCEMC, the tariff was amended to exclude NCEMC and all other North Carolina wholesale customers from the undergrounding costs in light of another FERC decision on the issue last October affirming that North Carolina customers would bear no additional costs. (See FERC Upholds Cost Allocation on Va. Tx Undergrounding.)

The commission last week denied rehearing requests from VEPCO, which had argued against excluding several costs from the allocation. FERC said it was reasonable to exclude any costs that had not been shown to be directly related to constructing the projects underground.

The commission also denied rehearing requests from ODEC, Northern Virginia Electric Cooperative and Virginia Municipal Electric Association No. 1. FERC said it had already determined it appropriate to allocate incremental undergrounding costs to all Virginia customers in the Dominion zone, and that the only issue set for hearing was the appropriate amount of the costs to be allocated among those customers on a load-ratio share basis.

Factors in New PJM VRR Curve Still in Question

By Rory D. Sweeney

VALLEY FORGE, Pa. — PJM has altered one of its recommended revisions to its capacity auction demand curve in response to stakeholder pressure, and a coalition of generators is pushing for other changes.

Staff have agreed with stakeholder requests to recommend moving the curve 1% left, negating a 1% shift to the right when the curve was last analyzed in 2014 and reducing excess capacity. The recommendations are part of PJM’s quadrennial review of the variable resource requirement (VRR) curve in its Reliability Pricing Model capacity market construct.

The announcement came at a Friday meeting of stakeholders interested in revisions to the curve. Tanya Bodell of Energyzt also provided an analysis funded by the PJM Power Providers Group (P3) that argued for retaining the current model of combustion turbine as the curve’s reference resource. A reference resource is representative of a peaking unit in the energy market that derives a significant portion of its revenues from the capacity market.

PJM is recommending switching from the Frame F to the Frame H of a General Electric turbine based on an analysis it commissioned from the Brattle Group, but Bodell said Frame F allows for flexibility and modularity, which is currently favored over unit size by market participants. Characteristics of the Frame H units are “so 2000s,” she said, because they’re designed and being used for “large, baseload combined cycle applications.” She noted that no Frame H units are being installed as CTs in PJM’s territory, and there is no evidence they will be, while Frame F units are. The mismatch would result in an inappropriate demand curve, she said.

“Going solely for the least-costly estimated technology can really squeeze out a lot of innovation and a lot of long-term gains that you can get from new technologies that are coming in,” Bodell said.

Erik Heinle of the D.C. Office of the People’s Counsel thanked Bodell for the presentation and said it’s “worth considering” proposals for the F and the H frames as either CTs or CCs.

PJM is targeting Oct. 12 to make its filing for FERC approval, and seeking endorsement votes by the Markets and Reliability Committee on Aug. 23 and the Members Committee during a Aug. 31 teleconference.

PJM Market Efficiency Project Rules Could Slip Deadline

By Rory D. Sweeney

VALLEY FORGE, Pa. — With the opening of PJM’s next long-term transmission proposal window looming less than four months away, it remains unclear whether the RTO will have new rules in place for evaluating and selecting market efficiency projects.

That would mean that any rule changes discussed by the Market Efficiency Process Enhancement Task Force since February that aren’t in place by the window’s Nov. 1 start will have to wait another two years for the Regional Transmission Expansion Plan’s next window.

After a three-hour meeting on Thursday, stakeholders remain at odds about how to move forward. A nonbinding poll showed stakeholders were unable to find at least 50% consensus on any of six solution proposals to address how PJM evaluates and chooses the discretionary transmission projects, which aren’t necessary for reliability but are meant to reduce congestion costs.

The Package A proposal received 49% approval, but stakeholders remained at odds over whether to exclude facility study agreements from the base case unless needed for reliability; whether to use a $10 million versus $20 million threshold on project re-evaluation criteria; and how to calculate energy benefits.

Given the intractability, PJM’s Brian Chmielewski, who oversees the task force, said the group should not forward all six proposals for consideration at the July 12 Planning Committee meeting, but instead attempt to sort through the polling results to assemble three new proposal packages. Stakeholders allowed Chmielewski to create the composite proposals but then balked at sending just those three to the committee.

LS Power’s Sharon Segner said the changes were significant enough for the task force to take another poll, which was supported by representatives from transmission owners Public Service Electric and Gas and American Electric Power. Chmielewski expressed concern about the further delay.

“If we do another poll, we lose the Nov. 1 effective date,” he explained, because there won’t be enough time to get it through the stakeholder endorsement process and receive FERC approval. “Slowing down a month means you miss another two years of new rules. … I think we should go to that [PC] meeting with the intent of having a first read” and take the committee’s input, he said.

Segner suggested adding the new rules to the upcoming window after it opens if FERC would approve such a move, but GT Power Group’s Dave Pratzon expressed concern that such late changes could disadvantage bidders.

Pauline Foley, PJM’s counsel, said she wasn’t “comfortable” with making a determination on whether PJM would be willing to ask FERC for a waiver to grant the approval in less than 60 days. PJM’s Asanga Perera added that other stakeholders might complain about the bidding rules potentially being changed halfway through the process. The window runs through February.

“I don’t think it’s just PJM’s call,” Perera said.

On Friday afternoon, RTO staff opened a poll on the three new proposals and gave stakeholders until noon on Wednesday to respond, giving staff enough time to compile and report the results at the PC.

NEPOOL Votes for Press Ban, Discusses Fuel Security

By Michael Kuser

Fuel security was at the top of the agenda during the annual summer meeting of the New England Power Pool Participants Committee, which also featured presentations by ISO-NE’s external and internal Market Monitors.

Members attending the June 26-28 committee meeting at the Water’s Edge Resort and Spa in Westbrook, Conn., also voted to change NEPOOL rules to formalize the policy of banning the press from their meetings. NEPOOL is the only RTO/ISO stakeholder body in the country that bars the public and press from meetings.

The vote, which approved changes to committee bylaws and the Second Restated NEPOOL Agreement, passed with 79% in favor in a sector-weighted vote, according to a notice of action taken at the three-day meeting. The changes add a definition of “press” and bar anyone working for the news media from becoming a NEPOOL member or alternate for a participant.

Three members of the Members Subcommittee disagreed with the Participants Committee’s recommendation on the changes and made a dissenting proposal that would have made the press eligible for a non-voting membership for a $5,000 application and an annual fee. It failed with only 27% in support, with only the end-user sector strongly in support.

RTO Insider prompted the vote by having a reporter who lives in Vermont apply for committee membership as an end-user customer in March. NEPOOL has not acted on the application.

“As you know, your application raised some interesting issues for the Participants,” Day Pitney attorney Pat Gerity, who serves as legal counsel to the Membership Subcommittee, wrote in an email last week. “They continue to work through those. Thus, the status of your application is that it is still pending.”

The changes have been submitted to the entire membership for a mail ballot ending this week. Assuming approval, they will be submitted to FERC.

Consent Agenda

The Participants Committee unanimously approved two items on its consent agenda:

  • Revisions to the Tariff and Market Rule 1 to modify the allocation of costs of the Forward Capacity Auction and annual reconfiguration auction to improve the alignment with the auction clearing methodology under the marginal reliability impact demand curves. The changes include a new definition for “estimated capacity load obligation” and replace the use of the net regional clearing price and residual capacity transfer rights in the Forward Capacity Market settlement. The RTO will request an effective date of June 1, 2021, for the 12th Capacity Commitment Period. (Separately, the committee approved related changes to the RTO’s Financial Assurance Policy.)
  • Retirement of Appendix C (Demand Response Holidays) of Operating Procedure 14 (Technical Requirements for Generation, Demand Resources and Asset Related Demands) to reflect the removal of demand response holidays because of the implementation of price-responsive demand, which had been recommended by the Reliability Committee on June 12.

No to New Winter Reliability Program

A proposal to re-establish a winter reliability program for future winter periods failed to pass, garnering only a 50% vote in favor. Energy New England (ENE), a Massachusetts cooperative owned by the municipalities Braintree, Taunton, Concord, Hingham and Wellesley, proposed the measure.

ENE proposed continuing the same program rules as were used for winters 2015/16 and 2017/18. It said the Pay-for-Performance program, which took effect June 1 to replace the winter program, provides “little incentive to materially increase stored fuels” because rates are too low and there is excess cleared capacity for winter 2018/19. The PFP program increased financial incentives for resource owners to make investments to ensure their resources’ reliability during periods of scarcity.

ENE said the winter reliability program should remain in effect until implementation of a “market-based solution.”

The proposal previously failed to gain endorsement by the Markets Committee, winning less than 30% support.

Fuel Security

Fuel security occupied most of the agenda for the second day of the meeting, with Paul J. Hibbard of Analysis Group moderating presentations by Professor Anji Seth of the University of Connecticut Institute for Resilience & Climate Adaptation and Phyllis Yoshida, Sasakawa Peace Foundation USA’s senior fellow for energy and technology and former Department of Energy deputy assistant secretary for Asia, Europe and the Americas.

Seth’s report addressed climate change, concluding that many currently rare extreme events will become more commonplace over the next few decades as the climate adjusts to greenhouse gases already emitted, while natural variability could amplify or suppress the warming signal regionally.

Yoshida looked at the impact of the Fukushima nuclear accident on Japan’s energy systems and extrapolated lessons for New England on how a region with insufficient domestic resources can provide a resilient energy supply in the face of unexpected events. She recommended that policymakers ensure that electricity and natural gas market deregulation is transparent, increases competition and creates opportunities for new actors and new technologies and practices.

External Monitor’s Fuel Security Assessment

ISO-NE’s External Market Monitor David Patton of Potomac Economics gave a presentation on his firm’s 2017 State of the Market report, which included a fuel security assessment for a two-week period of severe winter weather.

The EMM’s baseline scenario found that more than two-thirds of all potential LNG and oil storage capability will be needed if the Everett Marine (Distrigas) LNG terminal retires. Under a “severe pipeline contingency,” the market will be slightly short with Distrigas in 2023/24 and short by the equivalent of 2,500 MW for two weeks without the facility, Potomac Economics said.

“Although the oil storage capacity and LNG import capability are high enough to satisfy the demand for these fuels during a severe winter event, it would require very high utilization rates — above those observed in the past,” the EMM said.

The system is projected to require a very high percentage of this capability if the Distrigas terminal is retired, the report said. “Additionally, even if this terminal does not retire, the demand for oil and gas will exceed the available supply under a severe pipeline contingency in the 2023/24 cold snap scenario. This suggests that under these conditions, ISO-NE would lose its ability to serve the load for an extended time frame.”

Continuing a long-term trend, New England saw the lowest electric demand in at least 18 years in 2017, driven by an increase in energy efficiency and, to a lesser extent, behind-the-meter solar. | ISO-NE

The EMM said “market design changes may be needed to ensure that generators have incentives to conserve limited fuel supplies and allow market prices to efficiently reflect these fuel limitations.”

2017 Wholesale and Capacity Market Costs Rise Sharply

Jeff McDonald, the RTO’s vice president for market monitoring, presented the Internal Market Monitor report on 2017 market performance, which found that “energy, capacity and ancillary service markets performed well, exhibiting competitive outcomes.”

Wholesale electricity prices reflected changes in underlying primary fuel prices and electricity demand, with costs last year totaling $9.1 billion, up 20% from the previous year, the report said. Capacity market costs were up 93% to $2.2 billion because of higher prices in FCA 8 in 2014, which covered the 2017/18 CCP.

The IMM reported 2017 energy market costs totaled $4.5 billion, up 9% from the previous year, while natural gas price averaged $3.72/MMBtu, up 19%. Electricity demand declined 2% for the year, and in Q3 dropped 8%, which helped offset the impact of higher natural gas prices.

New England’s fuel mix in 2017 was largely unchanged since 2015, with natural gas claiming a 48% share of energy generation and 39% of capacity.

Continuing a long-term trend, New England saw the lowest electric demand in at least 18 years in 2017, driven by an increase in energy efficiency and, to a lesser extent, behind-the-meter solar, the report said.

Patton Cites High Uplift, Capacity Concerns in ISO-NE

By Michael Kuser and Rich Heidorn Jr.

High uplift costs, market power and the capacity market highlighted the External Market Monitor’s concerns in the 2017 State of the Market report for ISO-NE.

Monitor David Patton of Potomac Economics briefed stakeholders on the report at the annual summer meeting of the New England Power Pool Participants Committee last week.

The Monitor said the energy and capacity markets were competitive, with little evidence of withholding, and that market mitigation was infrequent and effective. However, the pivotal supplier analysis found market power under high-load conditions and in the Boston area — the latter of which will diminish with the completion of the Greater Boston Reliability Project and the addition of the Footprint Power combined cycle plant.

The only mitigation measures that have not been fully effective are those on resources frequently committed for local reliability. “Although the mitigation thresholds are tight, the suppliers have the incentive to operate in a higher-cost mode and receive higher NCPC [net commitment-period compensation] payments,” the report said.

The NCPC payments contributed to high uplift charges of 42 cents/MWh last year, the Monitor said, more than double that for NYISO ($0.24/MWh) and MISO ($0.16/MWh).

The issue prompted two of the Monitor’s eight recommendations, most of which were repeated from its 2016 review. It said the RTO should change the allocation of “economic” NCPC charges consistent with “cost causation” principles and use the lowest-cost fuel — or lowest-cost configuration for multi-unit generators — when making commitments for local reliability.

Reserve Markets

The Monitor also made two related recommendations to reduce uplift, saying the RTO should eliminate its forward reserve market and create a day-ahead operating reserve market co-optimized with the day-ahead energy market.

It said more than three-quarters of day-ahead NCPC charges result from local second contingency protection and system-level 10-minute spinning reserve requirements. Because there is no day-ahead operating reserve market, the Monitor said, the costs are not reflected efficiently in day-ahead prices, resulting in excess reserve commitments and depressed reserve prices.

Creating a day-ahead reserve market would allow the elimination of the forward reserve market, which the Monitor said has “resulted in inefficient economic signals and market costs.”

Capacity Market Concerns

Capacity market issues prompted three recommendations, including a call for market changes to complement the Pay-for-Performance program that began June 1 to ensure fuel security under severe winter conditions.

The Monitor said that although PFP will provide incentives for generators to procure fuel for severe winter conditions, “it will not provide the planning and coordination that may be necessary to ensure that ISO-NE’s seasonal reliability criteria are satisfied. Thus, the ISO should evaluate whether it has seasonal planning needs for the winter that must be met to satisfy its overall reliability criteria.”

It also said it should replace its descending clock auction with a sealed bid procurement and reduce the availability of information about qualified supply before the auction. The current structure provides suppliers with information they can use to recognize when they can benefit by raising capacity prices, it said.

The Monitor recommended several changes to the RTO’s minimum offer price rule (MOPR): eliminating performance payment eligibility for units subject to the rule; capping the minimum price at the net cost of new entry; and exempting resources resulting from unsubsidized private investment.

Under PFP, the Monitor said, most of the value of capacity will come from performance payments. But because resources that skip the capacity auction can still earn the payments by producing energy during shortages, “the MOPR will not likely be an effective deterrent under the PFP framework. In addition, an uneconomic entrant will be able to depress capacity prices without selling capacity because it will lower the expected number of shortage hours.”

The report notes that unlike other RTOs, ISO-NE’s MOPR lacks a competitive entry exemption, which could interfere with private investment in new resources.

And it said the MOPR could raise prices substantially above net CONE (currently about $8/kW-month) because it sets the offer floor at the new resource’s actual entry cost. That could prevent state-sponsored resources from clearing in the Forward Capacity Auction, with the RTO instead clearing a conventional resource. Under the recently approved Competitive Auctions with Subsidized Policy Resources (CASPR) program, “clearing unneeded conventional resources will compel the sponsored resources to pay lower-cost existing resources to retire,” the Monitor said.

In addition to its formal recommendations, the Monitor also noted that several new resources that obtained capacity supply obligations (CSOs) have been delayed in recent years, with some failing to deliver their capacity during the capacity commitment period (CCP).

Consistent delays in delivery of resources have significant implications for market outcomes and efficiency and affect other participants, the Monitor said. “Delayed new projects lower the prices in the FCA(s) in which they cleared, and as a result, FCA prices do not reflect the actual realized supply and demand and the reliability of the system. In addition, other resources that obtained a CSO in the FCA with delayed resources would face additional performance-related risks under the PFP framework,” it said.

The Monitor said it supports the RTO’s efforts to develop tougher penalties for delayed resources but also encouraged it to consider switching to a prompt market, with the auction conducted immediately before the commitment period.

Coordinated Transaction Scheduling

The report recommended the RTO find ways to improve its price forecasting under its coordinated transaction scheduling (CTS) with NYISO, finding that real-time transactions between the two regions went in the wrong direction in 44% of intervals in 2017.

Although CTS’ performance improved last year, the savings were reduced by a small number of intervals with errors of more than $20/MWh.

The Monitor said errors in load forecasting and wind forecasting were the biggest problem, responsible for 23% of price forecast errors. Differences in timing and ramp profiles was the second largest contributor, causing 22% of pricing errors.
