RENSSELAER, N.Y. — NYISO year-to-date monthly energy prices averaged $34.72/MWh in November, a 5% increase from a year earlier, Senior Vice President for Market Structures Rana Mukerji told the ISO’s Business Issues Committee (BIC) on Wednesday.
Locational-based marginal prices (LBMPs) averaged $30.60/MWh for the month, up 8% from October and up 16% from November 2016. The ISO’s average daily sendout was 403 GWh/d, compared with 398 in October and a year earlier.

New York natural gas prices gained nearly 19% in November, averaging $2.92/MMBtu at the Transco Z6 hub. Prices were up 33.5% from a year ago.
Distillate prices gained 31% year on year, with Jet Kerosene Gulf Coast averaging $13.04/MMBtu, up from $12.30 in October. Ultra Low Sulfur No. 2 Diesel NY Harbor averaged $13.70/MMBtu, compared with $12.86 in October.
The ISO’s local reliability share was 20 cents/MWh, up 6 cents/MWh from the previous month, while the statewide share dropped 10 cents/MWh from the previous month to -50 cents/MWh. Total uplift costs were lower than in October.

RTC and RTD Efficiency
In reviewing NYISO’s Broader Regional Markets report, Mukerji highlighted the ISO’s effort to increase the consistency between real-time commitment (RTC) and real-time dispatch (RTD) modeling and identify improvements to look-ahead evaluations in order to improve scheduling and price convergence. The Market Issues Working Group reviewed staff analysis of the issue Dec. 5, and the ISO expects by the end of the year to release a whitepaper identifying efforts to further explore RTC-RTD convergence in 2018.
Mukerji also noted that PJM has asked NYISO to review the former’s proposed pro forma pseudo-tie agreement that would apply to New York Control Area generators that sell all or a portion of their capacity to the RTO. PJM would provide commitment and dispatch instructions to pseudo-tied generators, which would be committed and dispatched to meet the RTO’s — rather than NYISO’s — needs.
NYISO has expressed concerns about using PJM’s proposed pseudo-tie agreement but said it’s prepared to work with the RTO to evaluate potential alternate solutions acceptable to both grid operators. FERC last month issued an order (ER17-1138) accepting many of PJM’s proposed pseudo-tie rules. Rehearing requests on the order are due Dec. 15, and NYISO said it was still evaluating its options.
Mukerji said NYISO is also modifying the rules for documenting capacity imports across PJM AC ties. The ISO’s proposal would require load-serving entities to submit evidence that an external resource with a capacity award has firm transmission service across the ties on the same day installed capacity (ICAP) results are posted. The Installed Capacity Working Group last month reviewed sample document types that would satisfy the requirement, which is slated to become effective May 1, 2018.
NYISO is additionally negotiating with PJM on cost sharing for the Ramapo 3500 phase angle regulator that was replaced by Consolidated Edison in September and plans to hold a joint NYISO/PJM stakeholder meeting on the issue in early 2018, Mukerji said.
On/Off Ramp Rule Changes
The committee also reviewed a complete market design proposal for “on/off ramp” rules the ISO uses to decide whether to eliminate or create localities within its market. Randy Wyatt, senior market design specialist for the ISO, told the committee that the proposed methodology is based on reliability planning principles.
Wyatt said the project is designed to ensure that locality price signals allow developers to make informed and efficient investments that enhance grid reliability. The committee will take up the subject again in the first quarter of 2018.
Charter Update for Integrating Public Policy Task Force
NYISO Executive Vice President Rich Dewey presented a revised charter for the Integrating Public Policy Task Force (IPPTF), which he said incorporated “some, but not all” stakeholder comments received so far.
The charter states that the BIC will receive monthly progress reports from the task force and that “any potential changes to NYISO tariffs, agreements, manuals or any other guiding documents” will be subjected to the ISO’s governance process.
NYISO and the New York Public Service Commission jointly formed the task force in October to create a forum for stakeholders to discuss pricing carbon into the wholesale electricity market. The task force held its first technical conference on Monday. (See New York Hashes out Details of Carbon Policy.)
Dewey acknowledged that there had been some confusion about why a new group was needed and explained that planners realized that integrating the state’s policy on carbon into the power markets would require a high degree of coordination between the ISO and state agencies.
The IPPTF’s next public hearing is scheduled for Jan. 8 in Albany.
CAISO is floating a proposal that would extend many of the features of its day-ahead market into the footprint of the Western Energy Imbalance Market (EIM) while possibly averting some of the thorny governance issues related to regionalization of the ISO.
CAISO’s 2018 Policy Roadmap | CAISO
The proposal is part of a broader plan focused on improving CAISO’s day-ahead market to better deal with emerging trends in resource procurement and planning, the ISO said. CAISO is including the plan in its Draft 2018 Policy Roadmap, which will guide the ISO’s many ongoing initiatives over the next three years related to grid operations, markets, new resources and generator retirements.
But a proposed expansion of the ISO’s day-ahead market could face competition from other corners. Reliability coordinator Peak Reliability and PJM announced last week they will explore the development of markets and other services in the West. (See PJM Unit to Help Develop Western Markets.) Farther inland, Mountain West Transmission Group is advancing on plans to integrate its member utilities into SPP.
California’s efforts to regionalize CAISO’s operations have twice stalled in the State Legislature in the last two years over concerns the state would cede too much oversight of its grid to other Western states less friendly to its ambitious environmental policies. Those states, in turn, have been wary of submitting control of their transmission systems to an entity controlled by their much larger neighbor.
An industry source, who wished to remain anonymous because they were not authorized to speak publicly, told RTO Insider that several present and future EIM members were gathering in Phoenix this week to discuss changes to the ISO’s day-ahead market. But Idaho Power spokesperson Brad Bowlin could not confirm the meeting.
“Unfortunately, we are not able to respond to your questions about this,” Bowlin said. “Any information will have to come directly from CAISO.” Idaho Power is scheduled to join the EIM next spring.
ISO spokesman Steven Greenlee said he was not aware of the meeting.
Integrated resource plans, resource adequacy and CAISO markets must align to meet policy goals | CAISO
The ISO’s proposal would create something like an “RTO-lite,” allowing for each EIM balancing authority (BA) to retain its reliability responsibilities and assuring that states could maintain control over integrated resource planning. Under the plan, resource procurement would remain under the authority of local regulators that — along with BAs — would continue to direct transmission planning and investment decisions.
CAISO said its effort would target better load management, more integration of distributed resources and enhancements to the EIM. Primary among the challenges the ISO faces is a shift toward more renewable and distributed energy resources, and conflicts between resource planning and reliability planning that are driving an increased need for out-of-market reliability-must run contracts for natural gas plants. (See Board Decisions Highlight CAISO Market Problems.)
“Recent grid operations challenges [point] to [the] need for day-ahead market enhancements to better manage [the] net load curve in real time,” the ISO said in a presentation prepared for a Dec. 14 call about the roadmap.
Extending the day-ahead market to the EIM would improve scheduling efficiency and integration of renewables, and allow EIM participants to take advantage of enhancements to the market, the ISO said. The ISO re-prioritized its initiatives to focus on the day-ahead market changes as well as deferring development of some other market products.
CAISO is proposing changes to the day-ahead market to “address net load curve and uncertainty previously left to [the] real-time market.” These include 15-minute scheduling granularity and a “flexible reserve” product that pays resources for must-offer obligations in the real-time market to address load uncertainty. Also being contemplated is combining the integrated forward market and the residual unit commitment process.
Extending the day-ahead market to the EIM would require market members to align transmission access charge models, according to the ISO. It would also involve expanding congestion revenue rights across the expanded footprint and analyzing day-ahead resources so balancing areas don’t “lean on” each other for capacity, flexibility or transmission.
The ISO is also planning collaborative programs with the California Public Utilities Commission to better align resource adequacy planning with reliability planning and the changing grid.
The policy initiatives catalog lists CAISO’s many ongoing updates to market rules, the EIM, distributed resources, generation retirements and changing conditions on the grid. Part of the roadmap process is the February updating of the catalog.
The final roadmap is due to be posted on Jan. 10, and more stakeholder calls will be held prior to review by the CAISO Board of Governors on Feb. 15. The ISO will accept comments on the draft roadmap until Jan. 4.
CAISO day-ahead prices hit all-time highs for the second time this year during the third quarter, and the frequency of price spikes in the 15-minute and five-minute markets increased, the ISO’s Department of Market Monitoring said in its quarterly market performance report.
| CAISO
High temperatures in California drove up demand at the beginning and end of August and into September, according to the report. Load peaked at 50,116 MW on Sept. 1, just short of the 50,270-MW peak record set in July 2006. Trading that day also saw day-ahead system marginal prices soar over $200/MWh during a four-hour period and hit $770/MWh in one interval.
| CAISO
“These outcomes were primarily driven by tight supply conditions as a result of a number of factors in combination with high demand while a significant amount of solar production is ramping down during sunset hours,” the report said. Average 15-minute market prices increased during every month of the third quarter from about $34/MWh in June to more than $45/MWh in September because of higher temperatures and loads.
The Monitor also confirmed that software problems had caused day-ahead prices to hit record highs in the second quarter even after being mitigated. In its second-quarter report, the department had noted that prices should not rise after mitigation and said it was investigating the cause. (See Monitor: CAISO Q2 Prices Hit Record Despite Mitigation.) The third-quarter report said the error was fixed on July 22.
“The ISO has determined that a software error introduced in 2016 resulted in infeasible energy and ancillary service awards for resources in the market power mitigation run but not the binding market run in the day-ahead market,” the Monitor said in the third-quarter report. “The software error resulted in an erroneous increase in supply available in the market power mitigation run, causing prices in that run to be lower than they would have been had all awarded schedules been feasible.”
CAISO is “currently evaluating the impact of this error on the market power mitigation process on affected days,” the report said.
Day-ahead prices appeared to be competitive in most hours, the Monitor said, and total year-to-date wholesale energy costs are close to 2016 totals, after the prices are adjusted for natural gas and greenhouse gas prices. Higher gas prices resulted in larger overall energy costs for 2017.
Transmission congestion was low in the day-ahead market in the Pacific Gas and Electric and Southern California Edison service areas but caused prices to drop about 2% in San Diego Gas & Electric’s area. Congestion in the 15-minute market pushed up prices in PG&E and SCE and decreased SDG&E prices. Frequent congestion on the Doublet Tap-Friars 138-kV constraint created an export-constrained area, undercutting prices in San Diego.
The Monitor said its analysis of natural gas price volatility shows a limited need for increased bidding flexibility created by raising commitment cost and default energy bid caps. CAISO followed the department’s recommendation and reduced the Aliso Canyon real-time gas scalars to zero beginning Aug. 1, raising them again temporarily Aug. 4-7 because of hot conditions.
Congestion revenue rights auctions took in $9 million less than payments to entities purchasing those rights, increasing year-to-date ratepayer losses to $38 million and to more than $680 million since the market began in 2009. The Monitor for more than a year has been calling for CAISO to eliminate CRR auctions. (See CAISO Monitor Proposes End to Revenue Rights Auction.)
The Monitor will discuss the third-quarter report with market participants during a Dec. 20 conference call.
A Nuclear Regulatory Commission official said Tuesday that a team of the federal agency’s reactor safety engineers would likely recommend that the commission continue working on replacing a portion of its inspections with a self-assessment regime for operators of commercial nuclear power plants.
Tony Gody, NRC director of reactor safety in Region II (Southeast), said Dec. 12 that “the working group agrees that self-assessment, if implemented properly, can be very effective in finding latent conditions” and probably will be recommending further exploration of how to get there via a pilot program.
| NRC
Gody made his remarks at the end of the agency’s second public hearing in two months on the use of licensee self-assessments in the NRC engineering inspection program and other changes in the reactor oversight process.
The Director of the Office of Nuclear Reactor Regulation formed the working group in February 2017 to review the commission’s engineering inspections that verify the adequacy of facility design, operations and testing, and make recommendations on improving both their effectiveness and efficiency. The commission has a webpage with related documents, including public comment.
The Good and the Bad
“We need to collectively as an industry own our own licensing design basis and regulatory performance,” said Greg Halnon, vice president for regulatory affairs at FirstEnergy, which owns two nuclear power plants in Ohio and one in Pennsylvania. The plants are the Davis-Besse plant in Oak Harbor, Ohio, the Perry plant in Perry, Ohio, and the two-unit Beaver Valley plant in Shippingport, Pa., which collectively generate 4,000 MW.
“We’re not abdicating our responsibility; we’re maintaining and owning that licensing basis,” Halnon said.
Dave Lochbaum, director of the Nuclear Safety Project for the Union of Concerned Scientists, said the 17 years of the reactor oversight process “have resulted in safety improvements, there’s no doubt about that, but achieving success loses value if backsliding occurs. … Our concern is, some of the measures being contemplated are banking on that success at risk of undermining it.”

Gody said that if whoever is doing an inspection or a self-assessment applies scientific principles, “it’s going to be a good inspection or self-assessment. And the fact that your own folks are already so familiar with your procedures, and the fact that your own folks already have computer accounts, already know the processes at the facility, already know the licensing basis, is a good thing and a bad thing.”
The good thing is they’ll be more efficient, he said.
“The bad thing is they may have preconceived conclusions,” Gody said. “It’s critical that when that checklist is developed that critical thinking is considered. If you accomplish that one thing, you potentially eliminate the human factor disposition to not challenge your own conclusions.”
Lochbaum said he wanted to push back on the “fanciful notion that there aren’t any more legacy, latent issues out there. There seem to be plenty of latent issues from long ago that we still haven’t found. Fort Calhoun [in Nebraska] is a perfect example, which shut down in 2011 and didn’t restart for 30 months. During that time, they submitted something like 18 LERs [licensee event reports], with the youngest of those being 15 years earlier, so they were at least 15 years old. Several of those involved engineering issues.”
Getting to the point of metrics, Lochbaum said “we recommended before and recommend again that the NRC should have looked at those LERs to see if the expectations were that the engineering inspections should have or may have identified those before they were found during an extended plant shutdown.”
NEI Supports
The Nuclear Energy Institute supports self-assessments, saying plant operators already do their own inspections in advance of NRC visits. “We believe that licensee self-assessments could be an important part of a modernized approach to engineering inspections. Such a solution would be rooted in our cultural value of self-identifying issues,” Greg Cameron, NEI’s senior project manager for regulatory affairs, wrote the commission in July. “We hold ourselves accountable to identify conditions at our stations early and to resolve them in a timely fashion commensurate with their safety significance; the NRC verifies that accountability through regular resident inspector interactions and the biennial Problem Identification and Resolution inspection. Transitioning from direct inspection to oversight of self-assessment activities, where appropriate, strengthens this accountability.”
Concerns in Mass.
But the self-assessment concept is unpopular with some neighbors of Entergy’s Pilgrim nuclear plant in Massachusetts, one of three plants in the country classified in Column 4 — the worst performers in NRC’s grading system.
A citizens group, Pilgrim Watch, cited an email written by the leader of a federal inspection team, who wrote that “the plant seems overwhelmed just trying to run the station.” The internal email became public mistakenly.
“Pilgrim provides the perfect example why NRC nuclear safety inspections are necessary and why industry self-assessments would be dangerous,” the group wrote NRC. “Pilgrim cannot be counted on to conduct any complete or accurate self-assessment. The NRC’s own records prove that Pilgrim has regularly and consistently failed to follow established procedures, to report problems, or to take corrective actions even when the NRC tells it to do so.”
ALBANY, N.Y. — When pricing carbon into the wholesale electricity markets, remember to keep it simple.
Also: avoid unintentional emissions increases, mind the transmission needed, incent new renewable resources, abate emissions efficiently without hurting consumers, allocate revenues fairly, and leave the legal hassles for the due processes of regulators and NYISO.
Those were some of the stakeholder comments Monday at the first technical conference of the Integrating Public Policy Task Force (IPPTF), which was established in October by NYISO and the state’s Public Service Commission to explore the carbon pricing issue as laid out in a Brattle Group report.
Paul Hibbard of The Analysis Group facilitated two roundtable discussions, each with 23 stakeholders. The morning session addressed border adjustment mechanisms to prevent “carbon leakage,” a parallel increase in emissions in regions neighboring New York.
“You don’t have to have the absolute perfect solution to leakage to go forward,” said Mark Reeder, an economist who represents the Alliance for Clean Energy New York at NYISO. “You just need to get most of the way there. Say if you can knock out 80 to 85% of the leakage problems at a $40 carbon price, you bring it down in essence to the latest we have now with a fairly small [Regional Greenhouse Gas Initiative] price and you’ve done the job.”
In looking at leakage issues in RGGI states and California, Reeder said “the unit-specific approach and the resource shuffling is a real bad idea and does create a lot of problems. The example here is that a nuclear plant in Pennsylvania that’s just selling spot-in in Pennsylvania could sign a contract to sell it to New York, and if New York declares that clean, we could work on that later, but it doesn’t work.”
Resource shuffling refers to the practice of utilities scheduling their lowest-emission generators to serve areas with emissions caps, while letting heavier polluters simultaneously serve customers in other regions.
“It’s important to move forward with carbon pricing principles and not use leakage as a way to delay,” said Gavin Donohue, president of the Independent Power Producers of New York. “We don’t need to reinvent the wheel.”
“You really get different answers depending on how you think about the question,” said David Clarke of the Long Island Power Authority. “For example, if you have a uniform carbon tax on all sectors, you’d be thinking about offsets; you think about where are the places where folks can make the investments that have the largest carbon reduction at the lowest cost.”
Baseline Leakage
“When you’ve got regions surrounding New York with such a wide range of marginal emissions rates, to start with a broad-brush approach, applying the New York rate to all of them will have pretty obvious unintended consequences,” said Stephen Molodetz, vice president of Hydro-Quebec. “Quebec is zero or near zero and Ontario is close to that; then you’ve got PJM, which is a higher emitter than New York.”
Don Tretheway, CAISO senior adviser for market design and regulatory policy, said some power producers outside the ISO have a resource portfolio with a significantly lower emissions profile than the default emissions rate for their region. In those cases, the ISO wants to give them the benefit of having cleaner resources.
“That’s relatively straightforward to implement from a market standpoint,” Tretheway said. “We can have each of the individual resources put their estimate of carbon compliance costs into their energy bids and we can dispatch away and everything works.”
Tretheway noted how the roll-out of the Western Energy Imbalance Market (EIM) further complicated CAISO’s treatment of greenhouse gas costs.
“The complexity CAISO introduced with the Energy Imbalance Market is that, not only did we need to solve to meet load in California that has a [greenhouse gas] program, but we had to actually solve to meet load in other states that don’t, and that’s where we had to separate those greenhouse gas costs into separate bids,” Tretheway said.
Mark Younger of Hudson Energy Economics said “what California is doing now is probably a mistake. [New York] should have a very high bar on resource-specific carbon pricing. Just because you can contract with what is nominally a clean resource, doesn’t mean that you in any way affected what the emissions were in the neighboring area other than by the fact that there was a bigger import to New York, regardless of resource.”
Allocating Carbon Revenue
The afternoon roundtable discussed how — and whether — New York would allocate revenues collected from a carbon pricing scheme.
NYISO Executive Vice President Rich Dewey said, “We’re conflating a couple issues here. First and foremost, we need to decide if there’s going to be a fund. When I think about how the NYISO settlements process works today, that revenue amount only exists for the microsecond it takes to do the calculation in the settlement itself, so there is no actual fund.
“At NYISO we’re not setting the policy, we’re administering the market,” he continued. “Be that as it may, you may have the desire, for the greater good, to create a fund in some capacity. Then we have to decide where is that fund.”
Miles Farmer of the Natural Resources Defense Council said that if the PSC determines what load-serving entities must do with carbon revenues, “that’s bounded under the legal constraints of PSC ratemaking, and you can’t have just general slush funds of money the way that it happens with RGGI.”
NYISO Senior Manager for Market Design Michael DeSocio said that when considering a carbon revenue fund, “we haven’t actually talked about what does the rate look like. And there are components of the rate that go into various funds already — a congestion rent fund, there’s a loss fund — all of that money is already allocated in some way based on various other markets. We want to do this in a way that doesn’t unnecessarily increase the cost to customers.”
Kelli Joseph, NRG Energy’s director of market and regulatory affairs, said that making carbon pricing sustainable requires considering how RGGI moneys have been used for energy efficiency and incenting renewables in to help reduce greenhouse gases.
“The [Brattle] report assumes a certain marginal emissions rate that may not be true over time,” Joseph said. “Over time, those marginal emission rates are going to decrease and there’s probably not going to be anything left to refund because there’s not going to be a lot of carbon-emitting resources on the system.”
Scott Weiner, Department of Public Service deputy for markets and innovation, cautioned roundtable participants about getting caught up in the legal details so early in the planning process.
“It’s going to be a collaborative effort and will be vetted legally,” Weiner said. “We will subject everything to the governance processes of NYISO, so there are a lot of legal issues, and in the absence of specific facts … I urge you to leave the legal discussion to another day.”
Task force co-chair Nicole Bouchez, a NYISO market design economist, said they had decided to cancel the Dec. 18 task force meeting and will next meet on Jan. 8, 2018.
Questions Remain as PJM Continues Push for Price Formation Revisions
PHILADELPHIA — Stakeholders hoping to influence PJM’s plans for revising its price formation methodology had better move quickly. RTO staff unveiled their problem statement and issue charge on the topic at last week’s Markets and Reliability Committee meeting and hope to have it approved at the next one on Dec. 21.
“If you are going to follow up … please do so soon,” PJM’s Stu Bresler said of the proposal, which would create a senior task force “investigating energy and reserve price formation enhancements [to] … more transparently reveal the true cost of meeting system reliability needs.”
In advance of a decision looming at FERC to provide price supports for nuclear and coal-fired units, PJM has been campaigning for support of an alternative. It would remove the prohibition on letting inflexible generators — often large coal and nuclear plants — be the price-setting marginal unit in its real-time and day-ahead energy markets. It would also factor in start-up and no-load costs, which are currently set aside.
PJM says these “simplifications” were used during the development of LMPs to reduce the time necessary to successfully dispatch the system. Large inflexible units are often dispatched despite clearing prices that are below their offers and receive uplift payments that compensate them for their costs. Out-of-market uplift payments have been a source of stakeholder frustration for years. (See PJM MRC OKs Uplift Solution over Financial Marketers’ Opposition.)
“From the initial implementation of locational marginal pricing, given that it is an optimization … we made some simplifying assumptions up front,” Bresler said.
PJM’s plan wouldn’t eliminate uplift and calls for making additional lost opportunity cost (LOC) payments for flexible units with lower offer prices to reduce their output to balance load and generation. But the RTO argues that the reduced uplift and LOC payments combined would be a fraction of the current uplift payments.
Still, stakeholders have been cautious to endorse the plan and asked that it not be rushed into implementation.
James Wilson of Wilson Energy Economics, who consults with several consumer advocates within PJM’s footprint, said the RTO’s proposed timeline for completing the task force before the fourth quarter of 2018 is too ambitious.
Joe Bowring, PJM’s Independent Market Monitor, echoed that.
“This is a massive change. There’s no reason to not have thought it through carefully,” he said, listing other market components beyond the energy and reserve prices that would be “impacted” by the change, including financial transmission rights and rules for Capacity Performance, market-power mitigation and uplift.
“I ask you to get stakeholder input and consider other options,” said Greg Poulos, the executive director of the Consumer Advocates of the PJM States (CAPS).
Bob O’Connell of Panda Power Funds asked PJM to “reserve judgments” about what causes and solutions the task force could discuss.
“Impairing flexibility because of the way we’re paying suppliers, that’s something we need to talk about,” he said.
Gabel Associates’ Mike Borgatti requested education for market participants to update their modeling assumptions.
Susan Bruce, who represents the PJM Industrial Customer Coalition, asked that load receive “fair notice” of the changes and a way to measure what the impact will be. “We have a lot of load that’s locked in because of low energy prices,” she said.
DER Charter Endorsed
After several contentious discussions at previous MRC meetings, members endorsed by acclamation the charter for the Distributed Energy Resources Subcommittee, which will consolidate PJM’s efforts on DER.
The charter had been contentious because of an addition that required all rules to “adhere to all pertinent jurisdictions” and regulators. Some stakeholders saw it as stating fact, while others were concerned it could be used to stifle discussion.
Bruce asked the group to be “extremely cautious” and that its proposals could result in costly requirements for “people who are not represented in this effort because they have chosen not to be in the PJM markets.”
PRD Rules Deferred
Stakeholders voted to defer a planned vote on new rules for price-responsive demand (PRD) pending the deliberations of the recently formed Summer-Only Demand Response Senior Task Force.
The RTO wants to change the PRD rules to comply with its CP requirements. PJM’s Pete Langbein attempted to characterize it as “just another [supply-side] option that would be out there that folks could elect to choose.” But state representatives complained that the proposed changes fail to acknowledge PRD’s value.
“It’s not a capacity product. It’s a mechanism to refine the load forecast,” said Morris Schreim of the Maryland Public Service Commission. “It’s not competing with supply.”
He argued against a change in the PRD rules that would “close the door” on solutions in the task force and suggested tabling the vote pending the outcome of the task force. Gregory Carmean, executive director of the Organization of PJM States Inc. (OPSI), agreed with Schreim that “it is time to take a pause,” saying it’s “hard to reconcile” the RTO’s justifications.
Langbein clarified that PRD displaces resources, either generation or demand response, with year-round capacity on a one-for-one basis. “That is the reality,” he said.
Calpine’s David “Scarp” Scarpignato called PRD “inferior” to generation in the context of CP and urged a vote. Waiting will make it harder to adjust the rules later as companies make decisions based on the current rules, he said. “We need this in place for the next [Base Residual Auction].”
EnerNOC’s Katie Guerry said it’s “alarmist” and “unproductive” suggest that all DR on the system would convert to PRD without the rule changes and said she was “looking forward to analyzing the opportunities” through the task force.
“Please participate in that process regardless of what sector you’re in,” she said, because that is where she sees any “real solution” being developed for summer-only DR that can no longer qualify as a capacity resource.
The deferral passed with just enough votes to clear the two-thirds threshold, receiving a 3.44 score (out of 5) in a sector-weighted vote.
Stakeholders Have Questions Before Approving MOPR-Ex
The Monitor will hold a question-and-answer session Tuesday to address stakeholder concerns on its proposed revisions to the capacity construct. The changes to the minimum offer price rule (MOPR) are expected to be brought to a vote at the Dec. 21 MRC meeting.
The IMM’s proposal was the only one to receive more than 50% approval in a poll of the Capacity Construct/Public Policy Senior Task Force, which has been meeting throughout the year to address concerns about market distortions from subsidized generators. The proposal would extend the MOPR to cover all units indefinitely, though it would include several exemptions.
Bowring said the proposal is meant to create an incentive for subsidized units “not to exist in the first place.” He fielded enough questions that stakeholders asked for a separate forum before voting. Jason Barker of Exelon, which had submitted its own proposal to the task force, questioned Bowring’s contention that the proposal is nondiscriminatory.
“Why do you think it’s appropriate to allow an overbuild?” he asked of one of the rule exemptions.
“I hear the point, and you’re right,” Bowring responded. “Let us think about that; it’s a good point.”
“You don’t have an answer to that? We’re going to have to vote on this,” Barker pressed.
“You’re not going to have to vote today,” Bowring replied. “We’ll have something out well ahead of the vote.”
PJM agreed to shorten its Dec. 12 Operating Committee meeting to make time for the Q&A.
For the second time in three months, no proposal from the Incremental Auction Senior Task Force received enough support to be proposed at the MRC, a fact that American Municipal Power’s Steve Lieberman argued should preclude PJM from automatically bringing its proposal for MRC review, even if it was just seven votes shy of the threshold at the task force. But Exelon’s Sharon Midgley moved for a vote on PJM’s Proposal A” and Bruce seconded it. The proposal received a first read and will be voted on at the next MRC.
“This is a compromise … but it’s all in the interest to try to get something before FERC so the issue of excess capacity and the sellback can get addressed, favorably for load,” Bruce said.
CPower’s Bruce Campbell argued the proposal doesn’t maximize the value of IA returns for load and said he was prepared to back another proposal “if others are interested,” but he received no support.
Other Voting Results
Stakeholders endorsed by acclamation several manual revisions and other operational changes:
Manual 11: Energy & Ancillary Services; Manual 18: PJM Capacity Market; Manual 27: Open Access Transmission Tariff Accounting; Manual 28: Operating Agreement Accounting; and Manual 29: Billing. The revisions implement PJM’s transition to five-minute settlements under FERC Order 825.
2018 day-ahead scheduling reserve (DASR) requirement. The final DASR calculation dropped to 5.28%, which was even lower than PJM’s preliminary estimates in October. The 2017 DASR was 5.48%. PJM attributed the year-over-year drop to reductions in average seasonal load forecast errors and the forced-outage rate. (See “DASR Requirement Drops Again,” PJM Operating Committee Briefs: Oct. 10, 2017.)
Tariff and Operating Agreement revisions to modify credit requirements for regulation and FTRs:
Regulation credits are accrued daily and billed monthly, while energy charges are accrued daily and billed weekly. Although the regulation-only resources’ credits are much greater than the charges, the weekly bills for charges create a credit requirement, even though the much larger credit is due to the provider at the end of the month. Daily regulation credits will now be included in weekly instead of monthly activity for calculating credit requirements. The change will apply to all resources, not just regulation-only resources.
FTR credit requirements for prevailing paths currently are based on weighted historical congestion on those paths, but transmission system upgrades can reduce congestion, decreasing the value of prevailing-flow FTRs. PROMOD simulation results will now be incorporated into the FTR credit calculator prior to the bid window to incorporate consideration of major upgrades and reduce default exposure to PJM’s members. (See “Give Them Some Credit,” PJM Market Implementation Committee Briefs: Oct. 11, 2017.)
Members Committee
Stakeholders Endorse Consent Agenda
Stakeholders endorsed by acclamation the committee’s consent agenda along with several other OA and Tariff changes:
OA revisions associated with PJM sharing of restoration planning generator data with transmission owners. (See “TOs to Receive Confidential Generation Data for System Restoration,” PJM Operating Committee Briefs: Sept. 12, 2017.)
Tariff revisions related to a proposed change in credit requirements for regulation resources. (See “Other Voting Results” above.)
Tariff revisions to FTR credit requirements to reduce exposure posed by congestion changes resulting from major transmission upgrades. (See “Other Voting Results” above.)
Nominees Approved
Members elected new representatives to the Finance Committee, sector whips and the Members Committee vice chair for 2018. It is the Transmission Owners sector’s year to choose a vice chair, and Chuck Dugan of the East Kentucky Power Cooperative was nominated.
California regulators are set to vote next month on a proposal that community choice aggregators (CCAs) be subject to the resource adequacy requirements of electric utilities.
The California Public Utilities Commission’s approval would require CCAs to comply with resource adequacy rules “in order to ensure that sufficient energy supply for customers is being procured by the appropriate utility.”

The proposal modifies the timelines for the creation of CCAs so that they are coordinated with the annual CPUC and CAISO resource adequacy and reliability programs. It would require CCAs to submit to a process that includes a timeline for submission of implementation plans; a ‘meet and confer’ requirement between the CCA and the incumbent utility that can be triggered by either; a registration packet including a CCA’s service agreement and bond; and a commission-authorized date to begin service.
It also calls for “universal access” to CCAs, equitable treatment of all customers and compliance with state laws regarding aggregated service. All prospective and expanding CCAs would be subject to the requirements for implementation plans received after Dec. 8, 2017.
CCAs are growing rapidly, creating some controversy over the stranded costs for regular utility customers. California legislators expressed surprise last summer when they were told that utility customers will be on the hook for hundreds of millions of dollars in long-term energy contracts procured by investor-owned utilities for customers who have departed for CCAs. (See California CCAs Spur Worry of Regulatory Crisis.)
The idea has been embraced by cities surrounding the San Francisco Bay Area that promote CCAs as “green” electricity programs. It was municipalities in the San Francisco and Los Angeles areas that lobbied for CCAs in response to a failed deregulation effort that in part caused the Western Energy Crisis of 2000/01. AB 117, enacted in 2002, allows local governments to form CCAs by aggregating retail customers and securing electricity supply contracts to serve them. CCAs also exist in Ohio, New York, Massachusetts, New Jersey, Rhode Island and Illinois.
Pacific Gas and Electric, which has opposed CCAs, argued to state lawmakers in August that about $180 million has been shifted from CCA customers to IOU customers — an amount it said will grow to $500 million by 2020.
California CCAs include Apple Valley Choice Energy, CleanPower San Francisco, Lancaster Choice Energy, Marin Clean Energy, Peninsula Clean Energy in San Mateo County, Redwood Coast Energy Authority, Silicon Valley Clean Energy and Sonoma Clean Power.
WASHINGTON — A panel on investing in grid innovation and clean energy infrastructure last week gave Congress low marks and said emerging economies are proving quicker to adopt some technologies. But speakers at the GridWise Alliance’s GridCONNEXT conference said they are bullish on the future.
David Yeh, a White House adviser during the Obama administration who is now managing director of Capitol Hill, an advisory firm for high net worth individuals, global asset managers and start-ups, said he is not overly concerned with the Base Erosion Anti-Abuse Tax (BEAT) provision in the tax bill passed by the Senate earlier this month. Some renewable advocates fear the language, which is intended to prevent multinational corporations from moving profits and jobs out of the U.S., will reduce the value of wind and solar tax credits.
“Right now clean energy, especially at the utility scale, is competitive, if not cheaper than, fossil fuel energy. So, you can talk about regulation; you can talk about policy. But economics will trump all of that.
“This year, clean energy funds raised about $5 billion, while fossil fuels have raised about $2 billion. That’s showing what the demands are from the … capital providers [and allocators] of this world. … These are sovereign wealth funds; these are pensions; these are large, super high net worth families. … This is how the capital markets — and these are capital markets that start with a ‘T’ — trillions — view clean energy infrastructure. When they move their allocation from 1% to 5%, that’s a game changer. And they’re moving towards that.”
Nancy Pfund, founder and managing partner of DBL Partners, predicted that there will be few gas-fired peaking plants built in California in the future.
“They’re expensive. People don’t like them. They’re [crude] compared to solar and storage or wind or demand response or any combination. That’s an example that you have to let go of what the 20th century was all about. This is really different and if you stand in the way … of consumers who want their solar or want batteries, they are going to run you over.”
An ‘F’ for Policymakers
Policymakers in D.C. haven’t heard that message, however, she said, as reflected in “the $4 billion worth of annual subsidies that the fossil industry gets.”
“If the people on Capitol Hill were in a public policy class or business school course, they would get an ‘F’ because [they are subsidizing] an industry that’s 100 years old. I think anyone in our [clean energy] industry would say we would love a level playing field. Get rid of all incentives. But it’s kind of a ‘David and Goliath’ story at this point.”
Puon Penn, executive vice president and head of technology capital for Wells Fargo, said investors would be wise to look past the U.S. to China and other growing economies that have committed to abandoning the internal combustion engine in favor of electric vehicles.
“Do you think the [original equipment manufacturers] … the Fords and the GMs are looking at the United States as their primary market today? They sell more vehicles in China. And if you’ve got to make electric vehicles for the Chinese market, you’re damn well not going to make a bunch of internal combustion vehicles for the United States. You’re just going to build one platform that you’re going to distribute across the planet. It’s inevitable. But people are still behaving like we’re still [the] Jolly Green Giant walking the earth and determining the order of things. We’re not anymore.”
Penn said new technologies are allowing greater capacity utilization in the electric industry than in the past. “There’s no other industries where you have high [capital expenditures] and such low capacity utilization,” he said. “Today we do have the wherewithal to increase capacity utilization and therefore benefit the entire economy.”
WASHINGTON — Speakers at the GridWise Alliance’s GridCONNEXT conference last week left no doubt: Electric storage is long past the “tipping point.”
Moderator Ram Sastry, vice president of infrastructure and business continuity for American Electric Power, had posed the question: “Are we going to see large-scale deployment of energy storage systems? And if not, what’s stopping that?”
“I think we’re at or past that tipping point,” responded Andy Marshall, practice director for distributed energy resource management at Landis & Gyr. “I think you see the flexibility of storage and its ability to get deployed relatively quickly. You have not only the stuff that’s going on down in Australia, but you also have the things that are happening most recently in California.”
On Dec. 1 — the first day of summer for Australia — Tesla turned on a 129-MWh lithium ion battery, the world’s largest, to help the nation’s fragile electric grid. California deployed 100 MW of storage in just six months in response to natural gas constraints following the Aliso Canyon leak.
Praveen Kathpal, vice president of AES Energy Storage, said “the technology is mature,” noting that his company entered the business a decade ago. AES claims 500 MW of storage already deployed or in development.
“There haven’t been any components that needed to be invented for any of the deployments that we’ve done, because they’re all based on lithium ion battery technology, which was commercialized 25 years ago and has benefited from its use in the consumer electronics and transportation sector,” Kathpal said.
“The tipping point we see in storage is really meshing with some of the other megatrends facing our industry right now. We have the accelerated growth in renewables, and we also have the electrification of more sectors including transportation.”
Kathpal predicted new storage technologies will break below the current pricing floor for lithium ion. “So, 10 years from now, do I think we’ll have a commercially available storage technology that’s below $100/kWh? Sure. And that’s exactly why at AES the technology platform we’ve developed is forward compatible with technology change.”
“I think you could argue that the tipping point was several years ago when big PJM systems started to come online,” said Luke Witmer, lead research engineer for Wärtsilä’s Greensmith Energy. “More and more markets continue to value the fast-ramping and bidirectional capability that energy storage provides. And I think as … systems continue to decline in cost, we will compete in more and more markets. A lot of the market prices basically clear according to the natural gas price. … So it’s really just a matter of getting renewables plus storage to below that threshold in more and more places.”
Richard Brody, director of sales and marketing for Lockheed Martin Energy’s energy storage unit, said storage is still relatively expensive when compared with energy efficiency and demand response.
“Whether we’re talking about a C&I customer or a distribution utility, when we come look at an energy problem, we look not just at storage, but we start with efficiency, permanent load reduction, load control, demand response, demand management, grid analytics — all the tools you can bring to solve an energy problem. … We tend to look at other things first because storage — despite the declining costs — remains the most expensive way to address these problems.”
But he is nevertheless bullish on storage. “In terms of the tipping point — oh yeah, we’re passed it. This is a rapidly growing market.
“We’re seeing very strong growth in interest in doing large solar and wind coupled with storage. Most of the large developers we’re working with aren’t contemplating any large development of solar — and increasingly wind — without some way to firm it up with a fairly significant storage system.”
Brody said the demands are exceeding the four-hour maximum life for lithium ion batteries. “We’re looking at much more ambitious efforts that would require the attributes of a flow battery, which is a minimum of six to 12 hours of energy.”
A Sierra Club report released last week that said captive customers of SPP utilities are paying for uneconomical coal plants has drawn considerable pushback from the RTO and some of its members.
But the head of SPP’s Market Monitoring Unit (MMU) says the environmental group has a point in its criticism of utilities that self-commit coal generators when the RTO’s market prices don’t cover their operating costs.
When a utility self-commits a unit, it operates the plant regardless of whether SPP’s market clearing prices are sufficient to cover the plant’s marginal costs. Although self-committed units are ineligible to receive make-whole payments from SPP, the Sierra Club says, some units are apparently recovering losses from captive customers through state ratemaking proceedings.
The Sierra Club report, “Backdoor Subsidies for Coal in the Southwest Power Pool,” alleges that utilities in the footprint operate coal plants outside the wholesale markets, generating $300 million in excess costs that consumers were forced to pick up in 2015 and 2016.
SPP and its members responded by saying the Sierra Club’s analysis relied heavily on wholesale rates, which aren’t the same as retail rates that are subject to public policy and regulations. Nor do wholesale rates consider the cost of long-term supply contracts or ensuring grid reliability, they said.
Keith Collins, executive director of the MMU, says that while the report took some of the MMU’s observations out of context, self-commitment is a problem in the RTO’s markets. MMU staff raised the issue in their 2016 State of the Market report, which Collins reviewed with SPP’s Board of Directors and Members Committee in July.
The Sierra Club said it conducted a “high-resolution analysis” of 14 coal plants in SPP’s footprint. It used hourly market data to develop each plant’s cash flow analysis.
“All 14 units operated for extended periods of time when, objectively, it would have been less expensive for the electric bills of utility customers for the plants to sit idle,” the group’s report said. “The utilities that own each of the 14 coal units we examined would have saved its customers money if the coal units had operated less often.”
The report said all but one of the 14 units studied were owned by state-regulated utilities, municipal utilities or an electric cooperative with captive customers.
Utilities should be purchasing electricity for its captive customers in the SPP Integrated Marketplace (IM), the report said. But it said some utilities “appear to be going back to state commissions and using rate cases and other dockets to obtain ratepayer-funded subsidies for costs incurred in operating otherwise uneconomic coal plants.”
“In the SPP market, where nearly half of the resources are self-committing, how much of an energy market can SPP really be claiming to operate?” the report asked. “The consequence of these facts is that the SPP Integrated Market is possibly a market in name only. The impact of utility self-commit and underbidding energy offers within the SPP IM might be the most anticompetitive and anti-consumer behavior in any integrated electricity market anywhere in North America.”
The report also says self-committed coal units are denying revenues to independent merchant generators. “RTOs are supposed to create nondiscriminatory rates, but allowing coal units to self-commit discriminates against those operators that don’t have captive customers to fund a ratepayer subsidy. Moreover, it is discriminatory and unreasonable for the market to ask one subset of customers to pay above-market costs while all other customers pay market costs.”
Collins told the board and members that self-commitment of resources has declined but is “still very big.”
“When resources are self-committing, it can put downward pressure on prices also,” he said at the time, referring to the effects of incorporating uneconomic resources in wholesale prices.
“The point of the [Sierra Club’s] report is consistent with what we noted in the 2016 annual report,” Collins told RTO Insider. “Self-commitment can distort the market. It’s a message we’ve been presenting as well.”
The MMU report noted generation offers in the day-ahead market averaged 48% as “market” commitments and 35% for “self-commit” in 2016. Those numbers were 46% and 39%, respectively, in 2015. Outages accounted for the remainder.
The Sierra Club report quoted the MMU report, which said plants self-commit because of contract terms, low gas prices “that reduce the opportunity for coal units to be economically cleared in the day-ahead market,” long start-up times, and “a risk-averse business practice approach.”
Collins took exception to the Sierra Club’s claim that “reliability isn’t one” of the reasons why a unit might self-commit.
Although the MMU’s report didn’t cite reliability, Collins said, “reliability could play a factor where some of these resources self-commit. Our report identified a set of reasons for self-committing, rather than a complete list.
“We have been discussing this essentially since I’ve been here,” said Collins, a former FERC staffer who joined SPP in June from CAISO. “What are the factors [behind self-commitment]? What can we do to promote more market commitment? Some of it is education and creating awareness. At least there’s a dialogue there that’s begun.”
SPP Disagrees
SPP General Counsel Paul Suskie said in a statement that the RTO disagreed with the report’s fundamental assertion that “utilities’ option to either self-commit resources or purchase from the market equates to a subsidy and undermines the effectiveness and cost-efficiency of SPP’s Integrated Marketplace.”
Suskie said that “assessing the market’s fairness and effectiveness based on wholesale cost of electricity to consumers does not take into consideration a number of factors that may lead utilities to self-commit.” He listed contractual obligations, capital investments, public policy and fossil fuels’ contribution to renewable resources’ deliverability as among those factors.
“Our day-ahead market has functioned successfully for four years and, in that time, has reduced the cost of energy in our region by more than $1.25 billion while continuing to ensure the reliability of the grid,” Suskie said.
Peter Main, a spokesman for SPP member Southwestern Electric Power Co., said the company bids its generation into the RTO’s markets under its market protocols and will continue “to seek opportunities” to produce net energy revenues benefiting its customers.
“The Sierra Club report does not provide an accurate portrayal of the incremental (variable) costs and revenues associated with offering generation into the SPP Integrated Marketplace,” Main said in a statement.
Plant Operators Dispute Findings
According to the report, SWEPCO’s Dolet Hills and Pirkey plants in the East Texas-Louisiana region burdened customers with $210 million in costs in 2015 and 2016. However, SPP said the plants serve load in “locations in northeast Texas without significant wind.”
Oklahoma Gas and Electric, which owns two of the plants identified in the study, has said the units stopped self-committing into the market more than two years ago. Two other generators — Entergy-owned or co-owned plants in Arkansas — serve load in MISO.
Al Armendariz, with the Sierra Club’s Lone Star chapter, said he was confident the group has a “good handle on the cost to run these coal plants in SPP.”
Armendariz, who worked in EPA under President Barack Obama, said the Sierra Club compared the SPP LMPs paid to power plants in the immediate vicinity of the coal plants studied. The organization obtained operating data from S&P Global Market Intelligence, the U.S. Energy Information Administration and SPP in running its analysis.
“Our report is really a comparison of the revenue for electricity, compared to what it costs to actually run the power plant,” Armendariz said.
Rule Changes Sought
The Sierra Club would like to see several things happen, Armendariz said. “We think SPP should clarify its rules to require power plants to bid in their real cost of fuel and other variable [operations and maintenance] … in the day-ahead market.”
Armendariz also said the Sierra Club would like to see state commissions in SPP’s footprint “investigate this problem of self-commitment and disallow the recovery of costs borne by consumers when uncompetitive coal plants are operating.”
“Vertically integrated utilities should not be forcing their customers to pay the variable costs,” he said. “State commissions should not allow the recovery of those costs through the rate base.”
Asked whether the group planned to file a complaint with FERC, Armendariz told RTO Insider that the Sierra Club “is evaluating all avenues of legal recourse that may be available to rectify the problems.”
Both Armendariz and Collins agreed the problem of self-commitment is not unique to SPP. Collins said he saw self-dispatch at CAISO and “knows” it occurs in other markets. Armendariz said although uncompetitive coal plants are running in “virtually every market … the problem seems most acute in SPP.”
The MMU believes that will change as market participants continue to familiarize themselves with SPP’s day-ahead and real-time markets, which have been in operation for less than four years.
“It appears that resource owners are becoming more confident in the market and allowing the market to commit the resource instead of self-committing their resource,” the State of the Market report said.
The Monitor also said the market systems’ optimization algorithm is restricted to a 48-hour window. “Hence, large baseload resources with long-lead time and substantial start-up costs may not appear economic to the day-ahead market commitment algorithm,” the report said.
Collins said SPP’s Market Working Group has discussed a potential multiday optimization approach. A Tariff change has yet to materialize, he said, “but that could help address some of the concerns.”
