Less is More?

FERC last week proposed reducing the amount of ownership information that companies must provide to obtain market-based rate authority.

The commission allows companies to sell power at market-based rates if they and their affiliates lack, or have adequately mitigated, horizontal and vertical market power. Current rules require applicants to describe the activities of all upstream owners, often requiring sellers to submit multiple amendments to their filings.

The commission’s Notice of Proposed Rulemaking would require applicants to provide ownership information only for affiliates necessary for the commission’s market power analysis (RM16-3).

Sellers would be required to identify and describe two categories of affiliates:

  • “Ultimate affiliate owner(s),” defined as the furthest upstream affiliate owner(s) in the ownership chain; and
  • Affiliate owners with franchised service areas or market-based rate authority, or that directly own or control generation; transmission; intrastate natural gas transportation, storage or distribution facilities; physical coal supply sources; or access to transportation of coal supplies.

The NOPR also would clarify the types of ownership changes that must be reported to the commission.

The commission said the changes would be less burdensome for filers and more useful to FERC’s assessments.

Comments will be due 60 days from publication in the Federal Register.

PJM General Session Discusses Emerging Threats

By Rich Heidorn Jr.

WILMINGTON, Del. — When Terry Boston began working for the Tennessee Valley Authority in 1972, its bunkered control room was believed to be one of the targets near the top of the Soviet Union’s nuclear hit list.

Last week, when the retired PJM CEO said his goodbyes at a General Session on “Resiliency and Security,” the concern was not the Cold War but “black sky” risks and the need for “critical low-density engineering assets” to recover from them.

Three speakers talked about their work protecting the grid from natural and manmade threats.

Jeff Dagle spoke about the Pacific Northwest National Laboratory’s work using parallel processing to aid modeling of extreme events. The technology can help system operators comply with a new NERC standard requiring them to ensure that “multiple outages” don’t cause system instability.

“When you try to model these extreme events, you’re going deeper than traditional N-1 [contingencies]. You’re doing N-K type of analysis,” said Dagle, the lab’s chief electrical engineer for electricity infrastructure resilience. “So there’s many more thousands of possible events you want to simulate and try to understand. Unless you throw that on a parallel computer, you’re going to be there for a while waiting for an answer.”

The lab’s work with PJM to apply Bayesian model aggregation — the combination of multiple prediction models — to reduce forecasting errors in network interchange schedules won an R&D magazine award. “This has the potential to save big money” — tens of millions, Dagle said.

David Andrejcak said FERC has become “much more agile” since it formed the Office of Energy Infrastructure Security following the 2013 sniper attack on Pacific Gas & Electric’s Metcalf substation.

Andrejcak is deputy director of the office, which combines the agency’s expertise in electric, natural gas and oil infrastructure. The office identifies threats and examines infrastructure for potential weaknesses but has no enforcement role, unlike the Office of Electric Reliability, which oversees the development of mandatory reliability and security standards.

“By addressing these with the private sector owners, we find that we’re getting a whole lot more success,” he said. “We’re not involved in the standards process. We’re the collaborative branch of FERC.”

Andrejcak noted a Department of Homeland Security analysis that found that almost one-third of cyberattacks on critical infrastructure in 2014 involved the energy industry. “We’re a big target. No doubt about it,” he said.

The session’s keynote speaker was Jonathon Monken, vice president of U.S. operations for the Electric Infrastructure Security Council. The non-governmental organization worries about “black sky” hazards such as cyberattacks or electromagnetic pulses (EMPs) capable of generating a “widespread, long duration” outage that could result in mass migration.

Monken, EISC (© RTO Insider)

Monken said broadcaster Ted Koppel’s book, “Lights Out,” which highlighted threats that could knock out the Eastern Interconnection for weeks or months, was useful in publicizing the need for preparations, such as assembling critical low-density engineering assets — engineers with expertise in electrical relays.

“We have not yet experienced a power outage that … [results in a] widespread long duration outage. We’re talking about months in terms of the outage. We’re talking about tens of millions [of people] in terms of the footprint.

“We don’t have the capacity to evacuate New York City much less the Eastern Interconnection,” Monken continued. “There’s a wide deficit in terms of the capability required to respond and recover from something of that magnitude and duration.

“I’d rather have an EMP event than just about any of the other ‘black sky’ hazards that include things like earthquakes and cyber[attacks],” he added. “Cyber is difficult because it’s very unpredictable and it’s very deliberate, whereas EMP is a statistical event — it won’t necessarily hit everything everywhere. You’ll have sporadic outages based on percentages.

“Cyber is very deliberate. They’ll only hit where it hurts the most.”

PJM Markets and Reliability Committee Briefs

WILMINGTON, Del. — PJM will ask FERC to act within the next couple of months on its Capacity Performance compliance filings and any related outstanding hearing requests, Stu Bresler, senior vice president for markets, told the Markets and Reliability Committee on Thursday.

“PJM recognizes there is a fair amount of uncertainty among our asset owners and operators as to what will occur come June 1 and beyond,” he said. “The purpose of requesting FERC action is to achieve as much certainty as possible ahead of summer 2016.”

Staff expects to make the filing before Christmas.

Load Forecast to Include Distributed Solar

With eight objections and five abstentions, the committee approved manual changes that allow PJM to consider distributed solar generation in its load forecast.

“The reason PJM sees this as important is that this behind-the-meter generation of solar is by far the quickest growing component,” said PJM’s Tom Falin. “It’s really taken off the past three to four years … exponentially. We believe it’s important to recognize this phenomenon now in the forecast.”

In the near term, the model will affect only a few hundred megawatts, he said.

Steve Herling, PJM vice president for planning, said staff wants to act now so it is not caught flat-footed when solar’s growth increases.

“We don’t want to see the phenomenon like we did with energy efficiency variables, which we talked about for a couple of years and by the time we implemented a change it was a pretty substantial change,” he said. “We want to get it into the forecast so we can tweak it as it grows.”

PJM agreed to review the process in a year to see how accurate it is and if any changes need to be made. The revisions will be made to Manual 19: Load Forecasting and Analysis. (See “Distributed Solar to be Included in Load Forecast” in PJM Planning Committee and TEAC Briefs.)

In a related matter, the committee approved manual revisions that aim to prevent energy efficiency resources from being counted both as capacity and load reduction in the new forecast model. The changes will be incorporated in Manual 18: PJM Capacity Market and Manual 18B: Energy Efficiency Measurement & Verification.

The motion passed with 12 no votes and one abstention. Members had delayed the vote until after an additional education session regarding the proposed addback. (See “Members Ask for More Time to Consider EE Resource Manual Changes” in PJM Markets and Reliability Committee Briefs.)

Ways to Mitigate Risk in CP Market to be Studied

A controversial problem statement proposing to study ways capacity suppliers could minimize underperformance penalties by netting them against overperforming units was approved with 80% of a sector-weighted vote.

Those who supported the measure said it was needed to level the playing field between small and large companies and to encourage financial investment.

Opponents said it was a solution without a problem and threatened to unwind a core aspect of the Capacity Performance model.

Bob O’Connell, who brought the problem statement forward on behalf of PPGI Fund A/B Development, responded to consumer advocates who asked what the problem was by saying, “Investors are looking at the market and deciding whether to invest in the energy market or Hollywood films. If investors see too much risk in the market, they may wait several years to bring a project forward.”

Market Monitor Joe Bowring opposed the problem statement.

“This seems to me … an attempt to unwind some critical parts of Capacity Performance,” he said.

Lisa Moerner, of Dominion Energy Marketing, said the concept does not undermine the Capacity Performance construct.

“We plan to do everything we can to perform during an emergency event under CP,” she said. Such risk-mitigating opportunities just give generators more options to do so, she said.

“We’d much rather overperform than pay penalties,” she said. “If we can provide megawatt-hours rather than pay a penalty, how is that a bad thing?”

Jason Barker of Exelon said that while that company’s general policy is to endorse problem statements and let discussion take place, it would be voting against the problem statement.

“This is really an attempt to rewrite Capacity Performance before the ink is even dry and before we’ve had a day of performance under this plan,” he said.

“If you follow the problem statement through to conclusion, it would provide incentives for market participants to underinvest in generation assets, threatening reliability, and enable those market participants to go into a secondary market and find replacement capacity at lower cost than the established non-performance penalty.

“The level of investment and the level of risk should be reflected in capacity market offers.”

Committee Approves Manual Changes

Members endorsed the following manual changes:

  • Manual 10: Pre-Scheduling Operations. The changes define a generator planned outage and restrict scheduling planned outages during peak maintenance season; define generator maintenance outage; define unplanned outage and clarify notification requirements; and correct the definition of non-synchronized reserve.
  • Manual 11: Energy & Ancillary Services Market and Manual 28: Operating Agreement Accounting. Changes reflect Tariff revisions approved by FERC regarding the energy market offer cap that went into effect Monday (ER16-76). Cost-based offers for incremental energy are capped at $2,000/MWh and allowed to set prices. Costs above that cap will be recovered through an after-the-fact review and make-whole payments. Market-based offers for individual units are allowed to rise with their cost-based offers. (See PJM Members OK $2,000/MWh Energy Market Offer Cap.) There was one abstention and one objection to this issue.
  • Manual 14D: Generator Operational Requirements. Revisions reflect the annual review of the manual as well as revisions to the reactive testing process. Revises and renames the wind farm communication model, making it applicable to all jointly owned resources to avoid confusion among control room operators. Adds definitions of generator planned, maintenance and forced outages. There was one “no” vote on this issue.
  • Manual 39: Nuclear Plant Interface Coordination. Updates are the result of a three-year review and include safe shutdown loading requirements developed by the nuclear generation owners’ user group.

EPA Slams Brakes on Plant Repowering

By William Opalka

EPA has overruled New York officials and ordered an additional air quality review for a dormant coal-fired power plant in the Finger Lakes region whose owners want to convert it to biomass and natural gas.

Owners of the Greenidge Generation Plant on Tuesday wrote to the New York Public Service Commission to say the EPA Region 2 administrator rejected the state’s finding that the change from coal to either biomass or natural gas is not a “major modification.”

“The primary basis for EPA’s objection is that, if reactivated, Greenidge will be subject to the Clean Air Act’s … permit program as a new source,” EPA wrote on Dec. 7.

The 106-MW plant on Seneca Lake has been dormant for nearly four years. The owners are seeking to revive it and add a new supply line for natural gas. (See Finger Lakes Plant Seeks Gas Line for Repowering.)

The New York Department of Environmental Conservation had issued a draft permit that EPA said was incomplete.

“We strongly disagree with the EPA’s decision given that the New York Department of Environmental Conservation conducted a thorough and complete review before issuing this draft permit, concluding that Greenidge clearly meets all the federal and state standards for resuming full operation,” Greenidge spokesman Michael McKeon said in a statement. “We are currently analyzing the EPA’s response to determine how best to restart the facility as soon as possible.”

He said the company has 90 days to respond to EPA.

The state awarded Greenidge $2 million on Dec. 11 to renovate the plant in Dresden to allow it to burn 100% natural gas. McKeon said the plant would lose that grant — part of a five-year, $500 million Upstate Revitalization Initiative for the Finger Lakes region — if the delay lasts as long as a year.

Federal Briefs

The Associated Press published its findings of a yearlong investigation into the security of the U.S. power grid, and its conclusions are not heartening: About a dozen times in the last decade, foreign hackers have gained enough access to operational networks and power plants to allow them to control the flow of power over the grid.

The AP conducted more than 120 interviews with industry experts and government officials, most of whom spoke on the condition of anonymity. These sources said hackers from Iran, China and Russia have penetrated the grid and remain “stowed away” where they can strike at will. “If the geopolitical situation changes and Iran wants to target these facilities, if they have this kind of information it will make it a lot easier,” said Robert M. Lee, a former U.S. Air Force cyberwarfare operations officer.

In its report, the news service delved into one such attack on Calpine in August 2013, where hackers gained access to passwords and diagrams of multiple power plants. The AP’s sources pointed to aging network infrastructure — such as computers running on Windows 95 and boot up on floppy disks — used to manage substations and power plants that are simply unable to respond or even detect intrusions.

GOP Accuses EPA of Using ‘Covert Propaganda’

epaHouse Republicans are questioning the legality of EPA’s use of social media in its climate rule campaign. While not citing any specific alleged abuses, House Energy and Commerce Committee Chairman Fred Upton (R-Mich.) said that last week’s Government Accountability Office report accusing EPA of violating the law when promoting its water rule calls into question “the use of social media to promote other rulemaking activity.”

“For example, EPA undertook an extensive social media messaging campaign in support of its Clean Power Plan, authoring blog posts and posting messages on Facebook and Twitter,” Upton said in a letter to EPA.

An EPA spokeswoman said the use of social media was aimed at educating the public, not influencing policy. “EPA stands by its outreach efforts on the Clean Power Plan,” she said.

EPA Ruling Spurs Rise in Coal Ash Use

AmericanCoalAshSCAAThe beneficial use of post-combustion coal products — more commonly known as ash — surged in 2014, mostly because of the clarification of federal regulations governing its use.

The American Coal Association said 62.4 million tons of ash, or 48% of all ash produced in 2014, were beneficially used in various applications, such as fill. That is up 21% from 51.4 million tons used in 2013.

EPA signaled in 2014 that it was rethinking coal ash’s “hazardous material” designation, spurring increased use, the association said. The agency finalized disposal regulations in December 2014 and it was designated non-hazardous. Figures for 2015 are not yet available.

IEA says Global Demand for Coal Stalls in 2014

InternationalEnergyAgencySourceIEAGlobal coal demand stalled for the first time since the 1990s because of increased renewable energy production, more stringent environmental regulations and a decline in industrial use, according to the International Energy Agency.

The agency said that China’s declining appetite for coal caused much of the stall. Although the country continues to build coal-burning power plants, it is also increasing its use of hydro, wind and solar power.

The IEA said it predicts that coal will provide a significant but shrinking share of the world’s generation, from the current 41% to 37% by 2020.

Akron Company Gets $1.3 Million from DOE for Clean Steam Plant

EchogenSourceEchogenOhio company Echogen Power Systems is getting a $1.3 million Energy Department grant to develop a cleaner coal-burning power plant. The government’s Supercritical Transformational Electric Power program is providing it with funding to explore the use of supercritical carbon dioxide, or carbon dioxide at high temperature and pressure.

Echogen, which operates out of a former steel company building in downtown Akron, is using supercritical carbon dioxide technology to boost waste-heat capturing systems in industrial applications. It will use the money to develop a 10-MW demonstration plant to employ supercritical carbon dioxide in a coal-burning system. It says using supercritical carbon dioxide will require less fuel and produce fewer emissions.

Construction of the plant is scheduled to start in 2019, according to Echogen.

FTC to Review Energy Transfer, Williams Cos. Merger

The Federal Trade Commission is reviewing the proposed merger of Energy Transfer Equity with The Williams Companies. The $37.7 billion merger would create the third largest energy franchise in North America.

Energy Transfer and Williams confirmed that FTC would review the proposed combination of the two pipeline giants. The deal also needs FERC approval, which would have to rule that the merger would be in the public interest.

The FTC review will determine if any antitrust issues would arise with such a merger. One legal expert, Franklin G. Snyder of Texas A&M School of Law, said he believes there will be few roadblocks. “Reports so far suggest that the antitrust problems will not be too serious and that it would likely get FTC approval, but the FTC will certainly be looking very closely,” he said.

“There’s a flurry of activity right now” in the commercial sector, said David Schieren, chief executive of EmPower Solar in Island Park, one of Long Island’s largest installers. EmPower expects to see a 10% shift toward the commercial sector next year, to 40% of its overall business.

In recent years, fewer commercial customers have installed solar. The number of rebated commercial systems is down for the past three years, to just 59 as of the end of November, compared to a high of 235 in 2011. The total number of megawatts on the commercial side is increasing, however, from 4.1 MW in 2013 to 6.1 MW thus far in 2015, according to PSEG Long Island, the local utility.

Manufacturing Plant Given Cheapest Rate

The New York Power Authority has approved a deal to give cheap electricity to an aluminum smelter that had announced a plant closure. The deal will allow the Alcoa plant in Massena to stay open and save 600 jobs.

The price of power for the plant will be cut and future changes will be tied to the price of aluminum. Authority CFO Robert Laurie said the rate cut, which runs through March 2019, would cost the authority about $12 million annually in lost revenue. Laurie said the authority would likely not find another customer for as much power as the Alcoa plant consumes, which would have to be dumped onto the wholesale power market with “uncertain effects” if the plant closed.

Laurie said Alcoa will pay $12.25/MWh, the lowest electricity price of any NYPA commercial customer, and warned that other customers may approach the authority “to request similar treatment.”

University Completes Switch to Natural Gas

OhioUniversitySourceGovOhio University’s on-campus power plant burned its last ton of coal on Thanksgiving Day and is now heating its buildings with natural gas, a switch that was completed six weeks ahead of schedule. The university had set Dec. 31 as the deadline to switching fuels, but work on the changeover was completed early.

The university will be installing two permanent natural gas-fired boilers, a project due to be completed by September 2017. The plant’s two coal-fired boilers and the obsolete smokestack will be removed.

The university is now getting about 20% of its overall power from the temporary gas boilers, and is purchasing another 50% on the open market from renewable sources.

Regional Haze Rule Could Cost Coleto Creek $100M

ColetoCreekSourceGovA newly announced EPA haze rule could cost the Coleto Creek coal-fired power plant near Victoria more than $100 million.

The federal agency announced Dec. 9 its haze regulations for the state, which require it to reduce pollutants that impair visibility in national parks and wilderness areas. Coleto Creek and six other coal-fired power plants in the state will need to make expensive upgrades or retrofits under the new rule to cut sulfur dioxide emissions.

Coleto Creek, which is owned by GDF Suez Energy Resources North America, has five years to comply with the new rule.

El Paso Wants 67% Cut in EPE Rate Proposal

ElPasoElectricSourceElPasoEl Paso Electric’s proposed rate increase should be reduced almost $48 million, or 67% less than the utility has sought, the City of El Paso said in documents filed with the Public Utility Commission.

The city is asking the PUC to reduce the utility’s rate request from $71.5 million to $23.5 million, which would result in an overall rate increase of 5.5%, compared to the utility’s proposed 16.6% increase.

The city also is asking the PUC to reject the utility’s proposal to establish a special rate class for residential customers with rooftop solar systems, which would increase those customers’ rates more than regular residential customers.

Carbon Capture Project Gets Important Land Agreement

SummitPowerSourceSummiOdessa Development Corp. voted to extend the land agreement with Summit Power Group, allowing the company to build a $2.5 billion power plant that captures and stores carbon on a 600-acre site.

Summit officials signed contracts Dec. 7 with the primary companies that will construct the Texas Clean Energy Project, which will sell power, CO2, urea and sulfuric acid. Summit still must raise funding to build the plant, and it is targeting financial closing in spring 2016.

Before the extension becomes final, Summit must also gain the approval of Grow Odessa, the non-profit organization that initially acquired the proposed Summit site. The Odessa City Council has already approved the extension.

St. Albans Cow Manure Digester to Produce Power

GreenMtnPowerSourceGreenMountainGreen Mountain Power says it will build a manure digester in St. Albans that will turn cow dung from three farms into electricity and reduce phosphorous pollution into Lake Champlain.

The $8 million project, which will generate enough electricity from methane gas to power about 700 homes, will help meet about one-third of EPA’s target for reducing farm phosphorous runoff into St. Albans Bay.

EPA this summer set new pollution reduction goals for the state’s side of the lake. The digester process will remove much of the phosphorous from the manure. The fibrous byproduct from the process will be turned into animal bedding.

Legislation Proposed to End State Nuclear Ban

A bill that would authorize new construction of nuclear reactors in the state was introduced Dec. 14 in both houses of the Legislature. Supporters say zero-emissions nuclear energy sources are needed under the Clean Power Plan, while critics of the legislation say building nuclear plants is an expensive way to comply with the federal carbon-reduction mandate.

WEC Energy Group said new sources of power wouldn’t be needed for at least 10 years, given the company’s recent completion of new plants. Republican State Rep. Kevin Peterson said during a legislative hearing that his bill “simply reopens the door to technology that has advanced well beyond what it was when our state closed that door 30-plus years ago.”

During Gov. Scott Walker’s 2010 campaign, he promised to end the state’s more than 30-year moratorium on erecting nuclear plants. Currently, 13% of the state’s electricity supply comes from nuclear sources.

API, ANGA Merge in Cost-Cutting Move for Oil Gas Lobby

By Tom Kleckner and Rich Heidorn Jr.

WASHINGTON — With low oil and gas prices crimping the petroleum industry’s budgets, two major energy lobbying groups are combining forces. The American Petroleum Institute and America’s Natural Gas Alliance will begin 2016 as a single organization under the API banner.

API-ANGA-Form-990-Data-Charts-web

The move appears to be driven by a desire by members of ANGA — a smaller, newer organization — to trim costs. Seven of the 17 members listed on ANGA’s website are also API members.

API, founded about 85 years ago, has more than 625 members, including refiners, suppliers and pipeline operators. In 2013, according to its IRS filings, it had a staff of about 300 and a $49 million payroll, one-fifth of its $238 million budget.

ANGA, founded in 2009, has a staff of about 22 representing 17 dozen independent natural gas exploration and production companies. It reported $7.2 million in payroll in its $67 million budget for 2013.

Ominously, ANGA’s biggest source of income, program service revenue — dues — dropped by more than a quarter in 2013, from $76.7 million in 2012 to $56.5 million in 2013. API’s program service revenue dropped from $225 million to $210 million over the same period.

ANGA ran an operating deficit of more than $10 million in 2013, following a shortfall of $7 million in 2012 — this after running a surplus of $53 million as recently as 2010.

Data for 2014 is not yet available.

“As a single organization, the combined skills and capabilities bring an enhanced advocacy strength to natural gas market development,” API CEO Jack Gerard, who will remain in his position, said in a statement. “The combined association’s expanded membership will provide additional lift to API’s ongoing efforts on important public policy issues.”

ANGA president Marty Durbin will lead a new group at API that will handle the gas lobby’s interests. ANGA members not already affiliated with API will become full members.

The organizations did not return requests for comment on whether the merger would result in layoffs. In an email to “colleagues” Tuesday, Durbin named four ANGA staffers he said would be joining him in the transition, promising they would provide “a continued high level of engagement and expertise.”

Gerard earned $14.1 million in 2013. Durbin earned $767,000 after becoming CEO in May of that year.

According to The Hill, API spent $9 million lobbying Congress last year — more than any other energy trade group —  while ANGA spent $1.4 million.

Congress’ approval last week of a repeal of the decades-long ban on crude oil exports gave API a rare chance to celebrate lately. It said the legislation “will help bring U.S. energy policy into the 21st century.”

FERC Orders MISO to Shift Electric Schedule

By Amanda Durish Cook and Tom Kleckner

FERC ordered MISO Thursday to post its day-ahead market results earlier, saying the RTO’s current schedule doesn’t allow gas-fired generators enough time to procure fuel.

The commission said MISO had failed to comply with Order 809, which moved the timely nomination cycle deadline for gas to 1 p.m. CT from 11:30 a.m.

The commission ordered MISO to move the posting of its day-ahead market results “at least” 30 minutes earlier to 12:30 p.m. CT. It also ordered the RTO to set a notification time for its forward reliability assessment commitment (FRAC) that is “sufficiently in advance” of the gas evening nomination cycle (ER15-2256 and EL14-25).

In separate orders, FERC accepted Order 809 compliance filings by SPP and CAISO. Order 809, issued in April, also added a third intraday nomination cycle. (See FERC Approves Final Rule on Gas-Electric Coordination.)

MISO Filing

MISO submitted a compliance filing in July that proposed posting day-ahead market results one hour earlier at 1 p.m. CT and the FRAC notification time two hours earlier to 5 p.m. CT. It also proposed moving its day-ahead market trading deadline one hour earlier during daylight saving time, so that the deadline would be 10 a.m. CT year-round.

fercThe RTO also proposed reducing the day-ahead market solve time from four hours to three, saying that would meet Order 809’s requirement for posting post market results “sufficiently in advance” of the evening nomination cycle to allow gas-fired generators to obtain fuel and pipeline capacity while minimizing the impact on market participants.

MISO said the earlier publication of the day-ahead results would reduce costs by making up to 1,600 MW of longer lead notification generation capacity available. Similarly, the 5 p.m. CT FRAC notification time would allow consideration of up to 4,214 MW of longer lead notification resources.

MISO said its proposals were an effort to balance the Order 809 requirements against stakeholder preferences to maintain a day-ahead market deadline no earlier than 10 a.m. CT. Because most of its footprint operates in the Central Time Zone, MISO said, market participants use the morning hours to determine generation availability, develop forecasts and formulate bids and offers.

FERC not Persuaded

FERC said posting results ahead of the evening gas nomination cycle is not a substitute for posting in advance of the timely nomination cycle, which it said is “the most liquid time to acquire both natural gas supply and pipeline transportation capacity.” MISO’s proposed day-ahead notifications would overlap with the timely gas deadline, leaving generators no time to submit nominations.

The commission said MISO failed to demonstrate that moving its posting at least 30 minutes earlier “will be unduly burdensome or disrupt its markets.”

While MISO said it was not currently experiencing the gas scheduling challenges faced by PJM and the Northeast markets, FERC said, it had “recognized that in the future it could have scheduling difficulties as coal-fired plants retire.”

“For at least part of the year, MISO, like PJM, NYISO and ISO-NE, generally schedules its day-ahead market using Eastern Prevailing Time, which means that it has more time compared to SPP and CAISO during the morning hours to complete its day-ahead schedule in time to meet the 2 p.m. ET (1 p.m. CT) revised timely nomination cycle deadline,” the commission said. “Thus, it is not apparent how requiring MISO to move its day-ahead posting deadline in advance of the timely nomination cycle places an undue burden on the staffs of MISO and its stakeholders.”

The commission acknowledged that MISO’s stakeholders generally prefer to purchase natural gas during its most liquid period (natural gas price certainty) over being able to obtain pipeline service during the timely nomination cycle (quantity certainty). It said MISO should work with stakeholders to reduce its market solve times further “to allow market participants to submit bids reflecting increased fuel price certainty.”

MISO has 30 days to submit a new compliance filing.

SPP Change Approved

FERC, meanwhile, accepted Tariff revisions SPP submitted in August that moved the deadline for day-ahead market offers up 90 minutes to 9:30 a.m. CT (ER15-2377).

The RTO will now post day-ahead results at 2 p.m. CT, up from 4 p.m., and shorten the reoffer period to 45 minutes, with reliability unit commitment (RUC) offers due at 2:45 p.m. CT and results posted by 5:15 p.m. (See “Board Approves Gas-Electric Timeline Change” in SPP BoD/Members Committee Briefs.)

FERC said SPP had “identified characteristics on its system that justify its proposal not to publish its day-ahead market results prior to the timely nomination cycle,” noting its low risk of natural gas pipeline constraints and the impact changes would have on weather forecasting for its “extensive wind resources.”

The commission ordered SPP to submit an annual informational report for the next three years on its efforts to further align its gas and electric scheduling practices. SPP staff have said they can implement the changes — which will require new software — by next fall. The work is being done in conjunction with an enhanced combined-cycle project, at an estimated combined cost of $7.7 million. (See “Enhanced Combined-Cycle Project Moves Forward” in Board of Directors/Members Committee Briefs.)

No Change for CAISO

The commission also said CAISO had shown good cause why its existing day-ahead practices should not be changed (EL14-22).

CAISO’s July compliance filing said its load-serving entities feared less accurate supply forecasts with an earlier start to the day-ahead market. FERC agreed, saying “moving the close of the day-ahead market earlier could reduce the accuracy of demand, hydroelectric supply and variable energy resource output forecasts.”

The ISO’s day-ahead market closes at 10 a.m. PT and market results are published at 1 p.m. PT.

As with SPP, the commission ordered annual informational reports on CAISO’s efforts to improve coordination of gas and electric schedules.

Appeals Court Upholds FERC on West Coast Energy Crisis Case

By Rich Heidorn Jr.

The 9th Circuit Court of Appeals last week sided with FERC in the latest chapter of the long-running legal dispute over the California-West Coast energy crisis of 2000-2001.

A three-judge panel declined to overturn FERC’s decision to apply the Mobile-Sierra doctrine — which presumes that the rate set in a freely negotiated wholesale-energy contract is just and reasonable — in determining whether Pacific Northwest power buyers are entitled to refunds.

The judges also dismissed a challenge to the scope of evidence FERC considered in the Mobile-Sierra review, saying the issue was not ripe for its review.

California Deregulation

The case before the 9th Circuit stems from the turmoil that followed California’s deregulation of the electricity market in the mid-1990s, which resulted in skyrocketing spot prices in California and the Pacific Northwest, largely driven by market manipulation by Enron and other power marketers.

The petitioners, which include the city of Seattle, challenged several FERC orders issued following the 9th Circuit’s 2007 remand of the Port of Seattle case. In that case, the court reviewed challenges to FERC’s denial of refunds to wholesale buyers that purchased power in the Pacific Northwest spot market at unusually high prices.

The court ruled that FERC’s failure to consider evidence of market manipulation was arbitrary and capricious. FERC had to “consider the possibility that the Pacific Northwest spot market was not … functional and competitive,” the court ruled.

FERC was ordered to examine evidence of market manipulation “in detail and account for it in any future orders regarding the award or denial of refunds in the Pacific Northwest proceeding.”

In response, FERC said it would invoke the Mobile-Sierra doctrine, meaning the presumption that the contracts were just and reasonable could be overcome only if specific criteria were met, such as “where it can be shown that one party to a contract engaged in such extensive unlawful market manipulation as to alter the playing field for contract negotiations.”

FERC’s invocation of the Mobile-Sierra presumption meant electricity buyers would need to “demonstrate that a particular seller engaged in unlawful market activity in the spot market and that such unlawful activity directly affected the particular contract or contracts to which the seller was a party.”

FERC said it would not consider “general allegations of market dysfunction” because the Pacific Northwest spot market operated solely through bilateral contracts, unlike the California spot market, which used a central clearing price and a centralized power exchange.

In last week’s order, the court rejected FERC’s contention that it lacked jurisdiction to review the commission’s application of Mobile-Sierra. But it deferred to what it called “FERC’s reasonable determination” that Mobile-Sierra applies to short-term sales.

“The mere short-term nature of these spot sale contracts does not render FERC’s application of the Mobile-Sierra doctrine unreasonable,” the court said. “Although long-term contracts may play a special role in stabilizing the energy market … the Supreme Court has drawn the rule so that the presumption may be invoked with regard to any contracted for rate.”

Evidentiary Challenges not Ripe

The court said, however, that it lacked jurisdiction to rule on the petitioners’ challenges to restrictions that FERC imposed on the evidentiary proceeding. The petitioners said they should be permitted to introduce evidence of reporting violations, violations of obligations under the Uniform Commercial Code and state contract law, and violations by sellers that were not parties to the challenged contracts.

The court said the evidentiary orders are preliminary and lack the “definitive substantive impact” required for the court to assert jurisdiction.

It noted that “FERC has already shifted course on the ‘shape’ of the proceeding in a way that suggests some elements of its orders may not be sufficiently final for review. … Significantly, it appears that despite arguments raised by the petitioners, at least some evidence of bad faith may have been admitted in the [evidentiary] proceeding.”

The court said FERC’s final order resulting from the remand hearing will be reviewable and will allow a “more effective review of the evidentiary decisions since the court will be able to review all of the evidence taken together.”

ISO-NE Planning Advisory Committee Briefs

WESTBOROUGH, Mass. — Increasing the export limits at a substation in eastern Maine’s wind country could save millions in power costs and reduce emissions, according to a draft report presented to the ISO-NE Planning Advisory Committee last week.

iso-ne

The study was requested by SunEdison, owner of two wind farms totaling 147 MW, Stetson and Rollins, that are served by the Keene Road substation.

The area around the substation has a peak load of 38 MW, which has dropped in recent years because of the closure of nearby paper mills.

The study found that increasing the export limit from the current 175 MW to 225 MW could save $1.4 million to $5.7 million in production costs annually by allowing additional wind development in the area and displacing more expensive hydropower. The savings are based on production costs of $0/MWh for wind, $5/MWh for hydro and $10/MWh for thermal energy imported from New Brunswick.

CO2 emissions reductions could range as high as 35 kilotons with the displacement of fossil fuel-fired generation, the draft says.

“The transmission investment could be worthwhile then, as these market efficiencies could be met,” said John Keene, senior counsel at SunEdison.

ISO-NE spokeswoman Marcia Blomberg said the analysis was an economic study of hypothetical system changes. The RTO has not developed cost estimates for the transmission upgrades that would be required to increase the export limits, she said.

Transmission Assumptions

ISO-NE is proposing changes in the way it makes transmission planning assumptions to reduce subjectivity and better reflect the likelihood of transmission constraints and generator outages.

In a presentation to the PAC, ISO-NE identified potential changes, noting that the current base case assumption that two generators are out of service “may be too pessimistic in some cases, too optimistic in others.”

The proposed changes are in response to a 2013 problem statement by the New England States Committee on Electricity (NESCOE), which said the current planning procedure allowed too much subjectivity in base case development.

“The degree of latitude in the current transmission planning procedure can create inconsistency within the region and between the development plans of various transmission owners,” NESCOE said.

Region-of-Reasonable-Test-Assumptions-(ISO-NE)---content-web
ISO-NE is proposing using cumulative probability — the aggregation of the probabilities of specific conditions — to determine a “region of reasonable test conditions” for future planning studies.The RTO said the change would reduce subjectivity and better reflect the likelihood of transmission constraints and generator outages.

The group proposed the use of statistical parameters to narrow the range of assumptions, which it said could increase the uniformity of transmission planning analyses among utilities and expedite state siting proceedings.

ISO-NE proposes using cumulative probability — the aggregation of the probabilities of specific conditions — to determine a “region of reasonable test conditions.”

Under current practice, disturbances are typically studied at peak load levels in steady-state analysis, which usually results in more pronounced thermal and voltage responses. The RTO uses 100% of the projected 90/10 summer peak load for the New England Control Area.

Going forward, the RTO proposes identifying the load and key resources that can stress transmission constraints and determine the likelihood of exceeding various combinations of load and unavailable generation. “This is similar to the installed capacity requirement, but not exactly the same way load is treated,” said Richard Kowalski, technical director of system planning for ISO-NE.

The RTO said its next steps include identifying the most appropriate weeks of the year and hours of the day to use in setting study periods and how to best model intermittent and distributed resources.
