VALLEY FORGE, Pa. — It took months to get PJM’s latest stakeholder initiative on the capacity market started, but there is no shortage of interest now that it’s begun.
More than 20 stakeholders attended the Capacity Construct/Public Policy Senior Task Force’s second meeting on Monday — with another 100 conferencing in — to spend more than five hours discussing 63 design-concept suggestions for revising the RTO’s capacity market.
Early on in Monday’s session, Steve Lieberman of American Municipal Power asked for confirmation that a suggested November timeline for deliverables is only a general target and not a specific goal. Dave Pratzon of GT Power Group suggested that such a deadline would allow revisions to be in place for next year’s Base Residual Auction.
Lieberman said the main focus should be to ensure the revisions are “complete and not half … complete.”
“There’s another word I would usually use there,” he added.
PJM’s Dave Anders, who facilitated the meeting, thanked him for not enunciating it.
One stakeholder noted that FERC has scheduled a technical conference May 1-2 on the interplay of state policies and wholesale markets in PJM, NYISO and ISO-NE (AD17-11). “If there is a compliance obligation that comes out of that tech conference, are we able to expand this task force to discuss it?” she asked.
Anders confirmed that the task force can vote to expand its scope in such a situation, but it must receive approval from the Markets and Reliability Committee to revise its charter. He went on to set other ground rules, including how the wide variety of stakeholder interests in this process will be handled. Instead of allowing “diametrically opposed” goals to both be approved as independent objectives of the group, he proposed using a poll to evaluate levels of support for each option.
“We’ll expose where the differences are,” he said.
Stakeholders took immediate interest in hashing out the definition of “missing money,” which NRG Energy’s Pete Fuller said should adhere to its original concept of focusing on revenue levels that support future investment, not on ensuring individual units are able to break even on a daily basis.
“It’s much more of a market-confidence stance,” he said.
Mike Cocco of Old Dominion Electric Cooperative agreed that the phrase “has lots of different meanings to lots of different people.”
To him, “missing money” means the additional revenue source from the capacity market that is necessary with a cost capped energy market to achieve the desired level of reliability. It does not mean revenue adequacy for all generators. He said the capacity market should provide the designed level of reliability at the lowest possible cost.
PJM’s Tim Burdis provided a review of state policy initiatives that are impacting, or could impact, the RTO’s capacity market. He said such initiatives tend to fall into four categories: standards to attain, such as emissions reductions; direct contracts; appropriations such as zero-emissions credits; and regulations.
Exelon’s Jason Barker took issue with categorizing ZECs as appropriations, saying they are more closely aligned with renewable energy credits, which Burdis had categorized as “standard attainments.”
The task force’s next meeting will be April 21. The location has not been set, but Anders confirmed that it won’t be at PJM’s offices due to scheduling conflicts.
NEW ORLEANS — MISO will soon make a filing to add more confidentiality and legal definitions to its alternative dispute resolution process, stakeholders learned at the March 22 Advisory Committee meeting.
With the changes, data exchanged during alternative dispute resolution meetings covered by nondisclosure agreements will be treated by the RTO as confidential or as Critical Energy Infrastructure Information.
MISO will invite other entities to participate in resolution meetings if their “participation is indispensable to resolution of the dispute.” The RTO will also be allowed to dismiss the dispute or “discontinue the informal dispute resolution process if such entity declines to participate in the dispute.”
MISO Deputy General Counsel Eric Stephens said the RTO already uses the concept of indispensable parties but is looking to codify it.
The revisions also clarify MISO’s ability to grant relief such as damages, which is “subject to the potential need for a waiver from FERC,” the RTO said.
MISO will also pass its responsibilities to recommend sanctions and give referrals for investigations to its Independent Market Monitor. Stephens said the RTO did not think it was appropriate to recommend sanctions or instigate investigations as a result of the resolution process. The new language also clarifies that MISO will not facilitate dispute procedures for contracts that are not service agreements or rate schedules under its Tariff.
MISO will also extend the initial timeframe for final resolution of an informal dispute from 90 to 180 days. “Our experience over the last two years has taught us that these take on average about 180 days,” Stephens said. He added that the timeframe could be extended by another 90 days before the RTO ends attempts to facilitate discussions, and the dispute is either dropped or escalated into a court proceeding.
The changes will be made to Tariff Attachment HH. (See “MISO Stakeholders to Hear Changes to Alternative Dispute Resolution,” MISO Steering Committee Briefs.)
Stephens said MISO will accept stakeholder input through April 12 and plans to file the new procedures for FERC approval by May 1.
NEW ORLEANS — In its first-ever current events discussion, the MISO Advisory Committee focused on moving on after the RTO’s failed capacity auction redesign.
MISO Executive Director of Market Design Jeff Bladen told the committee on March 22 that the RTO is open to revisiting discussion on another capacity auction solution only if stakeholders want it.
On Feb. 2, FERC rejected MISO’s proposed Competitive Retail Solution, which would have applied a sloped demand curve and three-year forward capacity auction to the RTO’s retail-choice areas.
The commission said bifurcating the RTO’s capacity market by holding a forward capacity auction for competitive load three years prior to the current Planning Resource Auction would create too much price volatility and uncertainty. A market-wide clearing process that operates within a single set of transmission capability constraints and supply offers is more efficient than a bifurcated market, FERC said. (See MISO Won’t Seek Rehearing on Auction Redesign.)
Entergy Vice President Matt Brown and other stakeholders said MISO should abandon its search for a solution to resource adequacy concerns in the competitive areas and focus on other ways to improve the PRA, including creating external resource zones and adding a seasonal aspect.
“I think our stakeholders have been very clear — and FERC has been very clear — that an Eastern-style capacity market is not right for MISO,” Brown said. “From our perspective … it’s time to let this go.”
NRG Energy’s Tia Elliott said Illinois’ legislation subsidizing nuclear plants and a Michigan law increasing the state’s renewable portfolio standard should not be considered a fix for climate warming concerns. Although the Trump administration hopes to kill EPA’s Clean Power Plan, MISO could be faced with similar environmental regulations in the future, she said. “The political landscape could swing again, and we could be back in the same situation.”
Minnesota Public Utilities Commissioner Matt Schuerger reminded stakeholders that ensuring adequate capacity is the responsibility of individual states.
OMS-MISO Survey Dispute Revisited
The committee also returned to stakeholders’ accusations that MISO and the Organization of MISO States have overstated a possible capacity shortfall through their joint resource adequacy survey. (See Differences Persist over OMS-MISO Survey Improvements.)
After a stakeholder pointed out that ERCOT was sued last year in an ongoing fraud case over misleading capacity reports, OMS member and Arkansas Public Service Commission Chairman Ted Thomas defended the survey.
“There isn’t a perfect way to do it. It’s a survey; it’s not a utility planning document,” Thomas said, adding that the survey was meant to help states understand their neighbors’ actions as they develop their own integrated resource plans.
Thomas said that if a utility is “dumb enough” to use the survey as a planning document, the utility deserves to get sued, not the producers of the survey. He also blamed local media for promoting a sky-is-falling narrative, saying reporters often don’t understand the survey results.
“Try explaining this stuff to a newspaper reporter,” he griped.
The economic and environmental challenges of replacing Indian Point are formidable. So are the grid reliability challenges.
Any attempt to minimize these impacts is a disservice to New Yorkers who face, at best, an uncertain energy future due to rising prices, higher carbon and other toxic emissions, and lower grid reliability.
For more than 40 years, Indian Point has been the backbone of New York’s electricity system. It generates 2,069 MW of power, providing 25% of the electricity for New York City and the surrounding region. In fact, the plant generates enough power for 2 million New York homes and the same amount typically produced by four or five natural gas natural plants.
Except for scheduled refueling outages, it generates baseload power 90% of the time, with no emissions. Even though we have up to four years to replace Indian Point’s power, it is very difficult to get anything approved and built in New York, including renewable energy facilities, in such a relatively short period of time.
Price Pressures
Replacing the supply of Indian Point’s power to meet the growing demand for electricity in New York will not be easy. But it is not only the resulting supply gap that puts upward pressure on electric power prices.
Improvements in the transmission grid necessary to bring new power to New Yorkers will be enormously expensive. Such infrastructure investments are particularly necessary and costly if the power must be transported over long distances, or if there is greater reliance on intermittent renewable power sources.
Other power sources are also subject to sharp price fluctuations. During the hottest days of the summer and the coldest of the winter, it is difficult for New York to get sufficient amounts of out-of-state natural gas, which also drives up prices at these critical times.
Also, the massive amount of renewable energy power needed to replace Indian Point is daunting and simply not practical. Replacing 1,000 MW, less than half of Indian Point’s generation, with solar power requires 45 to 75 square miles of land and 260 to 360 square miles for wind power.[1] For perspective, Manhattan is only 22.8 square miles of land.
Emissions
Indian Point also generates tremendous amounts of electricity with nearly zero carbon or other toxic emissions. The other critical question is not if toxic emissions will increase when Indian Point closes, but by how much.
California, Florida, Wisconsin and Vermont have all experienced greater reliance on fossil fuels and very significant increases in pollution after closing nuclear power plants.[2]
In fact, when advocating for New York’s upstate nuclear plants, Chairman of Energy and Finance for New York Richard Kauffman said, “Without our upstate nuclear fleet, 31 million tons of CO2 would be released in just two years, the equivalent of adding 6 million cars to the road — resulting in an additional $1.4 billion in public health and other societal costs. New York would have to rely on more expensive and dirtier power.”[3]
Grid Reliability
New York is fortunate that Indian Point will be operating until 2021. In fact, were the plant to close today, the state’s grid would not be reliable, according to NYISO.[4]
The costs of blackouts are enormous. The New York City comptroller found that the 2003 blackout cost the city more than $1 billion in lost wages, spoiled food and other costs.[5]
Blackouts are also a danger to public health. Researchers from Johns Hopkins University also studied the 2003 blackout and documented that it resulted in 90 deaths.[6]
Looking beyond the societal and economic costs of daylong blackouts, having an unreliable grid will make New York a very unattractive place to do business, especially for companies that are high-intensity users of electricity, such as manufacturers and high-tech companies.
Looking Ahead
Plans by state policymakers to address the issues resulting from the early shutdown of Indian Point should be transparent and thoughtful. Input from affected communities and organized labor are a must. We must address both environmental and economic issues to minimize adverse impacts on the regional economy and the ecology. Believing that Indian Point’s power can simply be replaced by energy efficiency or an enormous increase in renewables is not realistic.
New York consumers and businesses need to brace for the impact that Indian Point’s closing will have and be fully and clearly informed of what the impact will be in terms of monthly electric utility bills, air quality, and grid reliability.
Rob DiFrancesco is the executive director of the New York Affordable Reliable Electricity Alliance (New York AREA), a diverse organization of major business, labor, and community groups including Entergy, the owner-operator of Indian Point. Founded in 2003, New York AREA’s mission is to ensure that New York has an ample and reliable electricity supply, and economic prosperity for years to come.

Bernard W. Dan resigned unexpectedly from NYISO’s Board of Directors last week, less than a year after joining.
Dan announced his resignation at the board’s March 21 meeting. NYISO Chairman Michael Bemis relayed the news to stakeholders at the board’s Liaison Committee meeting afterward.
“Mr. Dan was interested in pursuing other opportunities,” NYISO spokesman Dave Flanagan confirmed. “He felt it was best to leave the board to avoid any potential conflicts.”
Flanagan declined to provide any details about Dan’s plans. Asked about plans to replace Dan on the 10-member board, Flanagan said, “Stakeholders will work that out through their normal process.”
Dan did not respond to an email asking for comment.
Turnaround Exec
Dan’s LinkedIn page describes him as a “Board Advisor, CEO and Turnaround Executive.”
He has been a senior advisor to the board of directors of OneChronos Group since 2015. The company, a startup that has gone through Y Combinator’s accelerator program, says it is building a new type of financial exchange that will make trading cheaper.
Dan was the CEO of Sun Holdings, which trades in stocks, currencies, futures and bonds, for five years ending in July 2015.
Dan also had a nearly two-year stint at MF Global, a broker of exchange-traded futures and options. After joining in June 2008 as the chief operating officer for North America, he rose to become CEO. He resigned in March 2010 and was replaced by former New Jersey Gov. Jon Corzine. The company, which filed for bankruptcy protection in October 2011, settled a lawsuit with its auditors, PricewaterhouseCoopers, on March 23.
Before joining MF Global, Dan was CEO of the Chicago Board of Trade, taking part in its initial public offering in 2005 and its sale to the Chicago Mercantile Exchange in 2007.
AUSTIN, Texas — The ERCOT Technical Advisory Committee agreed last week not to pursue a change in how ISO operators commit and dispatch resources, agreeing with a Wholesale Market Subcommittee study that the software changes required would not produce sufficient production cost savings.
The TAC then asked the subcommittee to begin working on real-time co-optimization of reserves.
The ISO developed an in-house software platform to perform multi-interval real-time market (MIRTM) simulations for selected operating days from 2015 and 2016. The study found MIRTM is feasible for both fast-responding generation resources and load resources with temporal constraints. But the feasibility study concluded that “the estimated cost[s] are in excess of the measured benefits and therefore insufficient to support [moving] forward with MIRTM at this time.”
ERCOT’s real-time market dispatches and prices energy in single five-minute intervals and does not consider potential changes in system conditions more than five minutes into the future. As a result, it is unable to coordinate the commitment of combustion turbines and demand response resources that are available within 10 to 30 minutes but unable to respond within five minutes.
The study was ordered to determine whether the ISO could improve the efficiency of its short-term commitment decisions by analyzing multiple consecutive five-minute intervals to determine the most economical commitment and dispatch.
ERCOT will share the study with the Board of Directors during its April 4 meeting. If approved, the study will be filed with the Public Utility Commission of Texas.
The WMS now finds itself freed up to take on real-time co-optimization, which shifts the responsibility for providing reserve services to online generation resources with the lowest incremental energy cost. Co-optimization has been the subject of discussion at the PUC, most recently during its last open meeting. (See Texas PUC Wary of Using ERS to Avoid Local Blackouts.)
“We’ve been waiting for [MIRTM] to clear the decks, and the decks have been cleared,” Morgan Stanley’s Clayton Greer said.
“We have an obligation at this point to explore this,” Citigroup’s Eric Goff said. “[The PUC] has given various hints that they’d like additional information. As a stakeholder body, I believe we have the obligation to make those hints and wishes reality.”
TAC Vice Chair Bob Helton, of Dynegy, agreed. With members raising concern over ERCOT’s estimate of $20 million for software changes, he directed the WMS to define a study scope and what components of co-optimization should be analyzed.
Staff Shares Draft Principles for Market Continuity
ERCOT staff shared with the TAC a draft of principles to address the ISO’s lack of guidelines on restarting its markets following outages. The principles do not change existing black start procedures.
Staff raised the issue last year with the board and conducted a workshop in May to frame the discussion around gaps in the processes.
The principles include:
Prioritizing the real-time market’s restart before other markets or activities;
Starting congestion revenue rights auctions and other functions only after the real-time and day-ahead markets are restored;
Expecting limited settlements functionality during market restoration;
Payments being made in “as timely a manner as possible;”
Relaxing credit requirements and releasing cash or other collateral to provide short-term liquidity to market participants;
Seeking emergency funding to pay resources before other alternatives are considered; and
Uplifting market restart costs on a load-ratio share basis after market recovery.
ERCOT staff is expected to build on the principles with more formal procedures.
“This is a good start. ERCOT didn’t have transparent principles before,” Direct Energy’s Read Comstock said.
Committee Approves 16 Revision Requests
The TAC also approved nine other NPRRs, three revisions to the Planning Guide (PGRRs), two revisions to the Load Profiling Guide (LPGRRs) and revisions to the Retail Market Guide (RMGRR) and Nodal Operating Guide (NOGRR).
NPRR776: Aligns protocol language with currently used verbal communication practices between transmission service providers (TSPs), qualified scheduling entities (QSEs) and generation resources. Also identifies new requirements for data TSPs provide to ERCOT, QSEs and the generators. The committee tabled NOGRR167, which aligns the Nodal Operating Guide with NPRR776.
NPRR799: Requires that TSPs and resource entities — generation and load that can reduce electricity usage or provide ancillary services — submit updates to the outage scheduler within one hour of the facility’s outage start or completion.
NPRR802: Clarifies current settlement practices and protocol language, including how reliability unit commitment resources opting out of settlement are treated in calculating real-time online reserve capacity.
NPRR804: Clarifies that ERCOT should post both a systemwide network model and a set of station one-line diagrams, and that the model posting does not disclose data about private-use networks.
NPRR808: Extends the CRR auction process into the third year forward, revises the percentages sold in the auction’s long-term sequence and aligns modifying load zones to the timetable.
NPRR809: Defines the terms “initial energization” and “initial synchronization;” adds a reference to a quarterly stability assessment for interconnecting generation resources when evaluating the need for a generic transmission constraint; and clarifies a resource’s requirements prior to initial synchronization.
NPRR810: Removes the applicability of a reliability-must-run agreement’s incentive factor to reservation and transportation costs associated with firm fuel supplies, and accordingly separates costs in the RMR standby payment equation.
NPRR812: Clarifies short-term system adequacy report language; aligns protocol language with current ERCOT practices and Public Utility Commission of Texas rules for posting resource and load information; and modifies the requirement for posting a RUC initial-conditions report to only include the process as originally intended in NPRR314.
NPRR813: Requires references to service organization controls for the annual ERCOT market settlement audits.
NOGRR166: Eliminates a redundant report of daily operational information that can be found elsewhere on the Market Information System.
PGRR052: Ensures a new generating unit’s operating limits are established by setting a timeline for stability studies following a full interconnection study (FIS), incorporating model data or transmission system changes, not known during the FIS, before a new unit is brought online.
PGRR054: Clarifies the content, review period and process for posting an FIS’ results, and establishes a process for identifying, proposing and implementing solutions to stability issues identified during the FIS.
PGRR055: Defines the process for revising the Planning Guide to first consider PGRRs at the subcommittee level.
RMGRR144: Eliminates the requirement for transmission and/or distribution service providers to maintain a secure list of retail electric provider data numbering systems for all electric service identifiers (ESI IDs) with “switch-holds” — measures to prevent customers with unpaid bills from changing retail electricity providers.
LPGRR060: Provides additional clarification to the load-profiling guide by removing “orphaned language” not captured in LPGRR057, which was approved by the TAC in October.
LPGRR061: Modifies the annual validation timelines for residential and business ESI IDs by starting the validation activities on March 30 and concluding them on Sept. 30 of each calendar year.
Though one director is reaching his term limit, MISO’s nine-member Board of Directors could look the same going into 2018.
Directors Thomas Rainwater’s, Paul Bonavia’s and Baljit Dail’s terms expire at the end of 2017. Rainwater and Bonavia have not reached MISO’s limit of three three-year terms, and both agreed to seek re-election by MISO membership for another term.
Dail has reached the term limit, but Board Chairman Michael Curran said at the March 23 board meeting that Dail has agreed to seek re-election for an additional term if a waiver is recommended by the Nominating Committee and approved by the board.
MISO’s Principles of Corporate Governance state that the term limit can be waived if the board determines “that a director’s continued service is necessary to retain his or her skills or expertise, to maintain geographic or other diversity of the board, or is otherwise in the best interests of” the RTO.
MISO’s board has seen considerable turnover in the past two years, with two directors — Phyllis Currie and Mark Johnson — added in late 2015 to replace former Director Eugene Zeltmann, and three directors — H.B. “Trip” Doggett, Barbara Krumsiek and Todd Raba — brought on in late 2016 to replace former Directors Judy Walsh, Michael Evans and Paul Feldman.
This year, stakeholders elected Arkansas Public Service Commission Chairman Ted Thomas to serve on the Nominating Committee. The vote for the second stakeholder seat ended in a tie between Madison Gas and Electric’s Megan Wisersky and Entergy’s Matt Brown. Stakeholder relations staffer Alison Lane said the vote for the second seat will be redone, with ballots sent out again this week. She said if all seven voting-eligible sectors participate, the vote cannot end in a tie.
MISO Market Software Adequate for Another 5-7 Years
MISO will be able to squeeze an extra couple of years out of its aging market system, said Dail, chair of the Technology Committee.
Late last year, MISO Executive Director of Market Design Jeff Bladen said officials expected to replace the system in two to three years, announcing that the RTO had hired consultants to study system improvements. (See MISO to Study Aging Software; Market Improvements Planned for 2017.)
But Dail said the system can take on more complexity and remain usable for five to seven years.
The RTO’s staff said the Clean Power Plan’s likely rejection by the Trump administration defers the need for new system technology, because intermittent and behind-the-meter generation is not expected to be added at such a rapid pace. Currie asked how much money MISO could expect to save because of the IT deferral. MISO CEO John Bear said the savings would be reported in future budget projections.
“That’s a welcome, but somewhat dramatic, change in timeframe,” Krumsiek said.
Dail also said that an internal technology audit again ranked MISO low when it comes to removing employee access to MISO systems after they are transferred or leave the RTO’s workforce. MISO had a self-imposed goal of 24 hours to remove both critical system access and perform an administrative cleanup. NERC standards allow 24 hours to remove an employee’s system access and 31 days to scrub employee information from the system. Dail said MISO has since allowed itself a more doable seven days to perform an administrative cleanup, separating it from the 24-hour access deadline.
MISO Operations Under Budget; Project Timing Nudges Capital Spending Over
MISO’s $37.7 million in spending so far in 2017 is under budget by $100,000, or 0.3%, newly hired Chief Financial Officer Melissa Brown said. She said the savings can be attributed to a slower hiring rate and MISO delaying some travel and the hiring of consultants.
However, MISO’s capital spending is over budget by 2.4%. Tony Guisinger, strategic development and operations executive, said capital spending is higher than planned because of some later-than-planned equipment purchases and related installation fees.
Guisinger, who assumed financial duties after former Vice President of Finance Jo Biggers left unexpectedly last year, is still assisting Brown, who joined MISO in late January. (See MISO Appoints Melissa Brown as New CFO.)
Board May Conduct Long-Term Incentive Review
Human Resources Committee Chair Todd Raba said MISO is planning a review of its long-term executive incentive plan.
The long-term bonus plan, which gauges and rewards performance for longer than one year, has not been changed in 15 years. Raba said his committee would complete a review of the current plan in June and act on proposed changes by October.
The board unanimously voted to grant RTO membership to two non-transmission-owning companies.
Clean energy project developer and operator ALLETE Clean Energy joined the Independent Power Producers sector, and transmission developer Verdant Plains Electric joined the Competitive Transmission Developers sector.
AUSTIN, Texas — Despite opposition from independent generators and competitive retailers, ERCOT stakeholders last week approved a protocol change that clarifies that the ISO can curtail DC tie loads without having to declare an emergency condition.
The Technical Advisory Committee on Thursday approved a nodal protocol revision request (NPRR818) that specifies that ERCOT may curtail DC tie loads during a watch, before declaring an emergency condition.
Representatives from two independent generators (Luminant and Dynegy) and three competitive retailers (Direct Energy, Just Energy and Reliant Energy Retail Services) abstained from the vote but made their opposition known.
Luminant’s Amanda Frazier said she was concerned about the way in which the NPRR was developed. It was written after ERCOT operators issued a power operations bulletin (POB) on Sept. 28 that changed the ISO’s operation of its five DC ties, which have a capacity of more than 1,250 MW. The POB, which took effect two days after its issuance, particularly affected exports into Mexico over Comision Federal de Electricidad ties.
Unilateral Action
“ERCOT has been curtailing DC ties in emergency situations. Then they unilaterally decided to stop doing that — and did that by issuing a [POB], a process not reviewable by stakeholders,” Frazier said. “That materially changed market outcomes for those market participants using DC ties into Mexico. I find that problematic. I think if something needs to be changed in the protocols that has major market impacts, we should know about it. We should be able to look at it, and we should know the policy decisions behind it.”
Luminant’s written comments recommended ERCOT only curtail DC ties during a Level 2 energy emergency alert (EEA), and not during a watch. It pointed out that voluntary load curtailment is not fully deployed until the ISO declares a Level 2 EEA. Involuntary load shed should not be used ahead of other “compensated, voluntary reliability deployments,” the company said.
‘Future Fix’
“I understand that wouldn’t work in a localized problem, but this language [isn’t limited to] a localized emergency,” Frazier said, “I don’t think it’s … appropriate to curtail DC ties before an EEA2 for a systemwide emergency, but I understand that’s going to be looked at in a future fix to this.”
Shams Siddiqi, representing Rainbow Energy Marketing Corp., the NPRR’s sponsor, told the TAC that “future fix” will be an additional protocol change.
Reliant Energy’s Bill Barnes said he would not oppose the NPRR given that additional revisions would be filed. He said that would fix “the problem we see: loosening reliability actions to allow these DC ties to be curtailed sooner, which has market impacts.”
“I think the ops team took what they viewed as appropriate actions, considering some of the changes that occurred,” ERCOT COO Cheryl Mele told the TAC, referring to the issuance of the POB. “The question I’m hearing is POBs with such a significant impact shouldn’t come out [two days] before we implement it. I concur with that. We should use the proper forums and processes.”
Mele’s comments related to recent changes in ERCOT’s capacity, including the Frontera Plant’s move from ERCOT to Mexico, and an increase in DC tie capacity, ERCOT spokeswoman Robbie Searcy said after the meeting. (See ERCOT Board OKs Rio Grande Valley Fixes.)
‘Fair Request’
Garland Power & Light’s Dan Bailey asked ERCOT to report back to the committee on how often curtailments are made during watch events.
“That is a fair request,” Mele responded. She said the reports will be filed with the TAC’s Reliability and Operations Subcommittee, “so you guys will be engaged.”
Rainbow Energy contended the NPRR would “minimize inefficient wholesale market operations and consequent harm to market participants.” The revision would be effective April 5, assuming ERCOT’s Board of Directors approves it the day before.
Before ERCOT issued the operations bulletin, it would accept DC tie e-Tags up to the physical limit of the ties, rarely curtailing the tags close to the operating hour.
Under the POB, e-Tags have been denied when day-ahead prices were relatively high while real-time prices were depressed and DC tie capacity was under-utilized, according to Siddiqi’s “business case” for the change. The result: “an avoidable inefficient outcome for the market and loss for the market participant,” Siddiqi said.
Siddiqi also said ERCOT prefers to take action in advance to avoid the chance of an emergency condition “and subsequent [NERC] scrutiny of why ERCOT did not act in advance to avoid the emergency.”
“Market participants wanting to export power have to procure power in the day-ahead market without knowing whether the e-Tag will be approved or denied,” according to the NPRR. “In turn, they are subjected to a loss and contractual difficulties with their counterparties if the e-Tag is denied.”
By allowing e-Tags to be curtailed in a watch before an EEA2, “ERCOT can revert back to its pre-POB operating procedure of approving e-Tags up to the physical limits of the DC ties,” Siddiqi said. “E-Tag approval can again be done prior to DAM [the day-ahead market] — allowing market participants to correspondingly procure energy in DAM and have the added certainty in its contractual obligations.”
“We have worked with Rainbow to implement what we understand the stakeholder’s intent, so we can be very transparent in the future,” said ERCOT’s Dan Woodfin, senior director of system operations. “The protocols don’t affect how we set limits today. With this change, how we set those limits will be clarified.”
WASHINGTON — President Trump signed an executive order Tuesday directing EPA to begin the lengthy process of undoing its Clean Power Plan, a centerpiece of American efforts to battle climate change.
Trump signed the order following remarks in the wood paneled Map Room at EPA headquarters, surrounded by his top energy lieutenants and a group of coal miners. “You know what this says?” Trump asked the miners, pen in hand. “You’re going back to work.”
Trump’s remarks followed those of Energy Secretary Rick Perry, Interior Secretary Ryan Zinke, EPA Administrator Scott Pruitt and Vice President Mike Pence, who noted the decline in coal mining jobs in recent years. “Those days are over,” Pence promised, “because the war on coal is over.”
“We’re no longer going to have regulatory assault on any given sector of our economy,” Pruitt said. “We’re not going to allow regulations here at the EPA to pick winners and losers.”
“Our nation can’t run on pixie dust and hope,” Zinke said.
The administration’s promises that coal mining jobs will return may be equally fanciful, however. Natural gas and renewable generation have become cheaper than coal-fired power in many regions, and the most productive mines are increasingly automated.
Years of Litigation to Come?
Trump’s bid to undo the CPP, meanwhile, could take years.
The Supreme Court stayed the rule in February 2016 pending a legal challenge by more than two dozen states that contended the rule overstepped EPA’s regulatory authority. The D.C. Circuit Court of Appeals heard arguments in the case in September. (See Analysis: No Knock Out Blow for Clean Power Plan Foes in Court Arguments.)
Legal experts differ on whether the D.C. Circuit will dismiss the states’ challenge based on the Trump administration’s withdrawal of support for the CPP. Environmental groups immediately promised to fight the reversal of the plan.
Trump’s order will put EPA officials in the odd position of having to contradict the findings the agency cited when it issued the final rule in August 2015, which incorporated feedback from 4.3 million comments and months of meetings with state regulators, utilities and RTO officials.

EPA also will have to overcome its 2009 finding that greenhouse gases endanger the public health and must be controlled.
Paris Agreement Threatened
Although the order does not indicate whether the U.S. will withdraw from the 2015 Paris Agreement on climate change, eliminating the CPP would make it far more difficult for the nation to meet its obligations to cut its carbon emissions to 26% below 2005 levels by 2025. The CPP requires a 32% reduction in power plant CO2 emissions from 2005 levels by 2030.
Economic consultancy company Rhodium Group estimates the U.S. would reduce carbon emissions by 21% below 2005 levels in 2025 under the CPP but that the reduction would flatten at 14% under Trump’s rollback.
The Paris Agreement is intended to prevent the planet’s temperature from increasing by more than 3.6 degrees Fahrenheit, which many experts say would lead to an irreversible future of rising oceans and extreme weather, leading to drought, flooding, and food and water shortages.
Other Provisions
The executive order also ends a moratorium on federal coal leasing and eliminates the requirement that federal officials consider the impact of climate change when making decisions.
Press Secretary Sean Spicer said the order directs federal agencies to review all rules “that put up roadblocks to domestic energy production and identify the ones that are not either mandated by law or actually contributing to the public good.”
It also orders a review of the standards for new generators, which effectively banned new coal plants without carbon sequestration. The levelized cost of a new coal generator with sequestration is about double the cost of new solar PV and wind, according to the Energy Information Administration.
Coal Jobs
EIA’s annual coal report last November found that U.S. coal production dropped 10.3% in 2015 to less than 900 million short tons, the lowest annual production level since 1986. Employment at U.S. coal mines dropped 12% in the year to less than 66,000, the lowest since the agency began collecting data in 1978.
More than 21 GW of coal generation retired in 2015 and 2016, largely as result of the Mercury and Air Toxics Standards, and EIA says another 14 GW is at risk of retirement by the end of 2028.
Energy economist Robert W. Godby, of the University of Wyoming, told The New York Times that Trump’s order could delay the closing of some endangered coal mines for as long as a decade. But because of increasing mechanization, “they’re not hiring people,” he said. “So even if we saw an increase in coal production, we could see a decrease in coal jobs.”
Economic Impact
Trump’s cabinet members portrayed the Obama administration’s environmental policies as a drag on the economy, with Perry decrying “poorly designed government policies, distorted markets” and a power grid whose reliability is being “tested because fuel diversity has been diminished in order to benefit one technology over the other.”
“The executive order will begin the process to unravel the red tape that’s been keeping investment on the sidelines and innovation stymied,” Perry said.
EPA’s Regulatory Impact Analysis of the CPP — which is not given credence by the agency’s critics — predicts the rule would produce economic and health benefits far exceeding its costs.
Critics say walking away from the Paris Agreement would hurt American leadership in clean energy technologies.
“The Trump administration is turning the nation’s back on the historic opportunity to build a clean energy future — a future that will modernize our energy system, offer consumers better value for their energy dollars and invest in state and local economies while taking the right steps to reduce climate pollution,” said Daniel Sosland, president of Acadia Center, which supports clean energy policies.
EIA predicts renewable electricity generation will grow 3.9% annually through 2030 without the CPP and 4.7% a year with it.
Regardless of what happens with the CPP, utilities, major corporations and many states are likely to continue their efforts at decarbonizing the generation mix.
New York Gov. Andrew Cuomo and California Gov. Jerry Brown issued a joint statement reaffirming their commitment to exceed the CPP’s targets.
“Climate change is real and will not be wished away by rhetoric or denial,” they said. “Together, California and New York represent approximately 60 million people — nearly one-in-five Americans — and 20% of the nation’s gross domestic product. With or without Washington, we will work with our partners throughout the world to aggressively fight climate change and protect our future.”
Reaction
Other reaction to Trump’s order was, unsurprisingly, mixed.
Environmentalists said the order could damage climate change efforts while producing no benefits for the coal industry.
“The fact that major utilities in Ohio are planning to shut down a number of dirty coal-fired power plants throughout the state should be an indication that the market is moving on to less costly and cleaner resources,” said Shannon Fisk, managing attorney for the Earthjustice coal litigation program. “We will be advocating to maximize energy efficiency and renewable energy as the best options for replacing coal plants, and for providing a just economic transition for coal workers and communities.”
David Doniger, director of the Natural Resources Defense Council’s Climate and Clean Air Program, tweeted: “Coal country needs a path to the economy of the future, not false hopes Trump won’t deliver.”
Paul Bailey, CEO of The American Coalition for Clean Coal Electricity, called the CPP “the poster child for regulations that are unnecessarily expensive and have no meaningful environmental benefit.”
The American Public Power Association also supported the president’s action. “Public power has previously voiced its legal objection to the rule for requiring utilities to fundamentally alter the way they generate electricity. In some cases, utilities would have been forced to abandon functional power plants while continuing to pay them off,” the group said.
WESTBOROUGH, Mass. — ISO-NE planners will make a several changes in their procedures in 2017, including revisions to Planning Procedure 3, incorporating probabilistic planning, a review of how the RTO identifies Bulk Power System (BPS) assets and a streamlined method of developing models, Director of Transmission Planning Brent Oberlin told the Planning Advisory Committee last week.
The process changes and the incorporation of updated load, energy efficiency and photovoltaic forecasts may have a significant impact on both the system’s identified needs and their year of need, Oberlin said.
Responding to stakeholder concerns about too much time being required for ISO-NE to complete needs assessments, Oberlin said that planners will move from a work flow based on serial preparation to one based on parallel modeling.
“We’re stealing from PJM here, which has inspired us to create generic case studies to look at all of New England at once rather than state by state,” he said at the March 22 meeting. “Right now, our start-to-finish case study process takes six months.
“After we talked to PJM, [we] kind of hit [ourselves] in the head” for not making the change sooner, Oberlin said. The current process is “serial, it’s slow and I don’t think it’s effective.”
ISO-NE plans to create a “library” of generic cases and study files for use in the future. Once the RTO and its transmission and other facility owners update the system topology data, the generic cases and study files will be updated with the latest load, energy efficiency, photovoltaic and resource data and posted for stakeholder review.
The RTO also is comparing its assumptions for classifying assets as BPS with those of other transmission operators in the Northeast Power Coordinating Council (NPCC). “It’s not lost on us that New England has more than half of the BPS classified substations within the NPCC, so we may revise the definition of what is a BPS,” Oberlin said.
The changes to Planning Procedure 3, which took effect Feb. 10, reduced the types of contingencies required for second contingency testing, limiting them to those with the greatest potential to impact the identification of system needs.
No longer required to be tested as the second contingency: the loss of two adjacent circuits on a multiple circuit tower and a permanent phase-to-ground fault with breaker failure. These second contingencies must still be tested under NPCC requirements, but solutions will be required only when the problems impact BPS facilities.
After more than a year of work with the PAC, the RTO will begin incorporating probabilistic dispatch methods in late spring, starting with the inclusion of probabilistically based local dispatches in the base system conditions used in needs assessments. The use of probabilistic methods will likely increase in the future, Oberlin said.
Eversource Towers Show Their Age
Eversource Energy engineering manager John Case showed slides of rusting steel and deteriorating concrete foundations to prove the need for replacing four aging towers carrying transmission lines over the Thames River in Connecticut.
About half a mile of the 1410/100 lines from Montville to Gales Ferry Junction shares double-circuit steel lattice towers that straddle the river at the Montville-Ledyard border.
“These structures were constructed in 1921 and have exceeded their planned life, and may have done [so] before I was born,” Case said to laughter. “And I am not a young man.”
Recent inspections of the structures revealed severe degradation of the foundation, towers and hardware. The four towers will be replaced with six galvanized steel poles at an estimated cost of $8.5 million (-25%/+50%).
