PJM Seeking RTO Consensus on Offer Cap Increase

By Suzanne Herel

PJM is seeking to reach a consensus with neighboring RTOs on a long-term increase in the $1,000 energy offer cap.

PJM CEO Terry Boston said that he proposed a joint approach to ISO-NE and NYISO at an ISO/RTO Council Markets Committee meeting last week. Boston said he also discussed the issue separately with MISO.

Boston told the Markets and Reliability Committee Thursday he wants to coordinate with the neighboring RTOs “so it doesn’t create a seams problem with people rushing across the border when there is a gas price spike.”

On Dec. 15, PJM asked the Federal Energy Regulatory Commission to raise the cost-based cap to $1,800/MWh through March (EL15-31). PJM made its request to FERC in a Section 206 filing after members failed to reach consensus over the past eight months. (See PJM Board to Seek $1,800 Offer Cap.)

Boston again expressed his disappointment in the deadlock. “Our ability to govern ourselves in the stakeholder process depends in large part on compromise,” he said.

Several members asked what will happen after March.

“We believe this issue is a broader national issue. We are hoping FERC would take this on,” said Andy Ott, PJM executive vice president for markets. “If we don’t see that occurring, we will have to take it up again.”

FERC OKs Tightened ISO-NE Screening on Capacity Imports

By William Opalka

iso-neThe Federal Energy Regulatory Commission last week accepted ISO-NE’s plan to increase its scrutiny of energy importers to mitigate market power in its capacity auctions.

FERC had issued a show cause order in September directing the RTO to strengthen market rules that prevented its Internal Market Monitor from fully evaluating the capacity bids of import resources. FERC had expressed concern that a declining capacity surplus had left the RTO vulnerable to market power abuses.

Under the previous rules, the Market Monitor determined only whether an importer’s bid was consistent with its actions in previous capacity auctions, rather than evaluating it against its net risk-adjusted going-forward costs, as is done for internal resources.

The revisions will allow ISO-NE to determine which new import resources have market power and apply mitigation to them in a way similar to what is applied to existing resources.

“ISO-NE’s current proposal represents a significant step to address the problem identified by the commission in the Show Cause Order, namely, the need to prevent resources participating in the FCA [Forward Capacity Auction] from exercising market power and leaving the auction at prices inconsistent with their net risk-adjusted costs,” FERC wrote (ER15-117).

The order is effective for FCA 9, which will be held in February for the 2018/19 delivery year.

Suppliers had asked for an opportunity to provide multiple offers in the auction, but FERC agreed with ISO-NE that there wasn’t enough time to implement required software changes for FCA 9. FERC ordered ISO-NE to implement the changes in time for FCA 10.

FERC also rejected a protest filed by Public Citizen to reopen FCA 8. The group had claimed that participants had used market power to increase prices, a contention the commission had previously rejected.

PJM to File Post-EPSA Demand Response Contingency Plan with FERC

By Suzanne Herel

PJM on Thursday announced a fallback plan to incorporate demand response into the capacity market in the event a D.C. Circuit Court of Appeals ruling limiting the jurisdiction of the Federal Energy Regulatory Commission is allowed to stand.

PJM General Counsel Vince Duane presented the contingency measure to the Markets and Reliability Committee, saying it would go into effect only if the U.S. Supreme Court rejects a request by Solicitor General Donald B. Verrilli to hear the case. Verrilli is expected to file a petition of certiorari on FERC’s behalf by Jan. 15.

Duane said that while the Supreme Court grants only about 1% of all cert petitions, some claim the success rate may be as high as 70% for those filed by the solicitor general. “I haven’t been able to validate that statistic,” Duane said. “But there’s no question that the odds increase significantly when the solicitor general makes a request.”

The plan, which will be submitted to FERC in a Section 205 filing in coming weeks, would allow any “wholesale entity” to submit “curtailment commitment bids” that would reduce the capacity procured in May’s Base Residual Auction. Duane said the term “wholesale entity” is “deliberately vague” and intended to include both load-serving entities and electric distribution companies.

The contingency plan is based largely on a white paper PJM released Oct. 7. That proposal came under criticism for limiting demand-side DR participation to load-serving entities. It is the electric distribution companies that oversee DR programs in several PJM states.

“This is a modest planning exercise to mitigate risk — but it does not avoid risk,” Duane said.

Duane said PJM can expect a decision on whether the Supreme Court will take up the case in March or April.

That won’t be in time, however, for the February incremental capacity auction, which will be conducted under current rules. (See EPSA Stay Complicates PJM’s 2015 Capacity Auction Plans.)

“If that’s ultimately found to be unlawful, it could undo that auction,” Duane said. “We face the prospect of an unsettled market outcome if the D.C. Circuit decision becomes the law of the land.”

The contingency plan is a “stop-gap” measure to allow time to develop a long-term solution, Duane said.

“We haven’t had an inclusive, broad stakeholder discussion … of what demand response should look like in the future,” Duane said. “We’re not suggesting in this filing we’re charting the future of demand response.”

PJM will request the commission act on the filing by April 1.

The contingency plan is a response to the D.C. Circuit’s May 23 ruling (Electric Power Supply Association v. Federal Energy Regulatory Commission) that overturned FERC Order 745. The court issued a stay on the ruling in October in response to a request from FERC. (See Awaiting FERC action, PJM Floats ‘Trial Balloon’ on DR Post-EPSA.)

The court ruled that FERC’s order, which required PJM and other RTOs to pay DR resources market-clearing prices, violates state ratemaking authority. While the ruling addressed FERC’s jurisdiction over DR in energy markets, PJM wanted to be prepared for it to be applied to FERC-regulated capacity markets.

Low Coal Stockpiles Boost MISO Off-Peak Prices

By Chris O’Malley

Depressed coal stockpiles have led to increases in MISO’s off-peak power prices and the cost impacts could increase with a repeat of last winter’s severe cold, officials said last week.

Coal generators in MISO, SPP and ERCOT have complained of difficulty obtaining coal for more than a year due to insufficient railroad capacity.

MISO clearing prices for fall were up 9% compared to fall 2013, with off-peak prices up 16%, due to increased coal-delivery costs and reduced output by generators seeking to conserve fuel due to low supplies, Todd Ramey, MISO vice present of system operations and market services, told the Federal Energy Regulatory Commission during a presentation at the commission’s open meeting Thursday.

MISO’s Market Monitor estimates that more than one-third of coal generation in MISO has implemented some form of coal conservation measures over the last six months, Ramey said.

Alan Haymes, of FERC’s Division of Energy Market Oversight, said coal stockpiles in the Midwest have declined since last year and are below five-year averages, although a mild summer helped mitigate the deficiency going into this winter.

“If the coming winter presents challenges similar to last year’s experience, the coal inventory problems could result in significant market impacts,” he said.

“It is likely the below-level stockpiles will persist through 2015 as railroads struggle to keep up with overall demand before system upgrades are complete. This is raising concerns among some generators that low stockpiles coming out of the winter could create challenges in the summer of 2015,” Haymes said.

Haymes said 166 power plants that burn coal from Power River Basin Mines in Montana and Wyoming have been struggling to maintain supplies because of insufficient capacity on BNSF Railway.

The railway has been pinched by an increase in shipments of grain and other cargo as the economy has improved. In addition, rail traffic to and from the Bakken oil fields of North Dakota have more than doubled since 2009, BSNF says.

Congestion in the east-west rail gateway in Chicago also has been a problem, said Michael Higgins, deputy director of the Surface Transportation Board.

coalA BNSF executive said the railroad is boosting capital expenditures and maintenance spending to $6 billion in 2015 from $5.5 billion this year. Last month BNSF said it would add 330 new locomotives to its 7,500-locomotive fleet.

The railroad, which serves 28 states and three Canadian provinces attributed some of the constraints to construction on its northern routes that increased congestion in the central part of its system. It says it expects to be rebuilding its customers’ coal stockpiles through 2016.

“We clearly understand that our service has not met customer expectations,” said Steve Bobb, an executive vice president of BNSF.

Commissioner Tony Clark asked BNSF whether and how the railroad determines which commodity receives priority during periods of tight constraint. Bobb replied that the railroad focuses on customers who report they have 20 days or less of inventory.

The commission also heard from Minnesota Power, which said that it experienced “severe” disruptions at its coal-fired plants last winter and at one point was down to a four-day supply of coal. Some units had to suspend operations; the utility purchased $27 million of higher-priced replacement power.

“The good news is that organized markets like MISO work and work well. We’ve had no electric service disruptions,” said David McMillan, senior vice president of external affairs at Minnesota Power parent Allete. “The bad news is that purchased energy prices were significantly higher than our own self-generation costs.”

Bloom Energy Surcharge Falls to $3.3M in January

A surcharge paid by Delmarva Power & Light customers to subsidize fuel-cell manufacturer Bloom Energy will come in at $3.3 million in January, down slightly from the previous month.

Under rules set by the Public Service Commission, a customer using 1,000 kWh will be assessed $4.52 for the Bloom Energy surcharge, down from $4.86 the previous month.

The PSC allowed Delmarva to collect the surcharge after declaring the natural gas used in fuel cells as renewable energy. The surcharge, which has generated nearly $63 million so far, was part of an economic incentive for Bloom to open a fuel cell manufacturing plant in Newark.

Opposition to Exelon’s Pepco Bid Rising

Exelon’s $6.8 billion acquisition of Pepco Holdings Inc. picked up new opposition during the Public Service Commission’s first public hearing on the merger last week.

A coalition including the Sierra Club, Chesapeake Climate Action Network, D.C. Working Families and the D.C. Environmental Network introduced itself during the five-hour session. The group, which calls itself Power D.C., also set up a website that calls Exelon “a Chicago-based utility with a bad record,” whose acquisition of Pepco will not benefit ratepayers or businesses.

Supreme Court to Hear FutureGen Sourcing Case

FutureGenThe state Supreme Court will hear Commonwealth Edison’s appeal of a Commerce Commission order requiring it to enter into supply arrangements with the non-profit, clean-coal FutureGen 2.0 plant.

The ICC’s order forces ComEd to buy electricity from the plant as part of the state’s renewable energy mandates. The Illinois Power Agency Act requires that a quarter of the electricity consumed in the state by 2025 be generated by cost-effective clean-coal plants.

FutureGen 2.0, a project plagued by construction delays and cost overruns, is one of the only clean-coal power sources in the state. ComEd and other utilities have argued that the ICC’s mandate excludes other out-of-state clean-coal sources. The court is expected to make a decision before the end of 2015.

Edwardsport IGCC Plant (Source: Duke)

The Office of Utility Consumer Counselor is asking state regulators to force Duke Energy to reimburse customers $114.8 million in costs that it says were associated with the startup of the problem-plagued Edwardsport coal gasification power plant.

The Utility Regulatory Commission allowed Duke to collect up to $2.6 billion from customers to offset the plant’s construction costs, but it prohibited Duke from passing on any costs relating to testing and startup.

Duke said the plant was operational in June 2013. But the consumer counselor contends the plant didn’t officially go into commercial operation until March 2014 and that Duke improperly passed on startup costs between 2013 and 2014.

PSC Eyeing Smart Grid Technology Soon

The Public Service Commission will hold two public hearings to investigate future investments in smart grid technology.

Advocates say smart grid technology, including smart meters, can allow utilities and customers to better gauge electricity consumption and to induce customers to conserve energy. None of the four investor-owned utilities in Kentucky – Louisville Gas & Electric, Kentucky Utilities, Duke Energy and Kentucky Power – have launched smart meter programs yet.

The PSC will record comments at the hearings and accept written comments until Feb. 27 before releasing recommendations sometime next year.

DTE Asking PSC for 3.2% Rate Increase

DTE is seeking a 3.2% rate increase – about $9.75 for an average customer’s monthly bill – to pay for system upgrades and power purchases, the company said in a filing with the Public Service Commission. The request would increase revenue $370 million for the Detroit company.

DTE said the rate increase would apply only to residential customers because the commission has already approved rate decreases for businesses and industrials. DTE said that commercial customers have been subsidizing residential customer rates for years.

DTE, which has about 2.1 million customers, said it has made about $3.5 billion in system upgrades in the past three years. DTE’s last residential rate increase was in 2010, when it asked for $444 million, and the PSC allowed $188 million.

JCP&L Rate Case Drags on for 3 Years, Lawmakers Angry

Consumer advocates and lawmakers say it is time for the Board of Public Utilities to make a decision in a three-year-old case involving Jersey Central Power & Light, the state’s second largest utility.

The Division of Rate Counsel in 2011 asked the BPU to force JCP&L to file a rate case, arguing that the utility was charging at least $200 million too much. The utility, whose parent company is FirstEnergy, filed a request in 2012 seeking a $31 million rate increase. An administrative law court judge has granted several delays but is expected to announce a recommendation on Dec. 29.

“This is simply too much,’’ said Ev Liebman, associate director of AARP’s New Jersey chapter. “It is actually worse that the BPU has failed to act on the petition to establish provisional rates.’’

“JCP&L has been shamelessly collecting too much money (from customers) for too many years,’’ state Sen. Linda Greenstein said.

PUC Considering Ban on Charging for Paper Bills

The Public Utility Commission is considering a ban on utilities assessing a charge on customers who want a paper bill, rather than an electronic accounting of their charges.

A four-year investigation into paperless billing found that paper billing invoice fees constitute “unreasonable and inadequate service.”

To date, no electric or gas utilities have separate charges for mailing a paper bill, a practice that has been limited to a few telecommunications companies. A rule prohibiting charging for a paper bill will be introduced next month.

XTO Energy to Pay $5M for Damaging Wetlands in Fracking Operations

The U.S. Environmental Protection Agency and the Department of Justice announced yesterday that XTO Energy will spend an estimated $3 million to restore eight sites damaged by unauthorized discharges of fill material into streams and wetlands during fracking operations in the state.

The company was also fined $2.3 million for violations of the Clean Water Act, which prohibits the filling or damming of wetlands and streams without permission of the U.S. Army Corps of Engineers. Half of the penalty will go to the state Department of Environmental Protection, a co-plaintiff in the settlement.

Officials said that the company,  a subsidiary of ExxonMobil, dumped sand, dirt, rocks and other fill material into streams and wetlands to construct well pads, road crossings, freshwater pits and other facilities during fracking operations in Harrison, Marion and Upshur counties. More than 5,300 linear feet of stream and 3.38 acres of wetlands were affected. The EPA said it was alerted to some of the violations by the state and discovered others through routine joint inspections conducted with the Corps. The company also disclosed violations at five sites following an internal audit.

NC WARN Asks FERC to Force Duke, Others into RTO

By Ted Caddell

A North Carolina environmental group last week asked the Federal Energy Regulatory Commission to force Duke Energy and other utilities in the Southeast to form a regional transmission organization to share power reserves, rather than keep building new generating plants and boosting prices to pay for them.

The North Carolina Waste Awareness and Reduction Network (NC WARN), a frequent critic of Duke, noted that the merger of Duke and Progress Energy resulted in Duke supplying 95% of the electricity in North Carolina either directly or through municipal providers or cooperatives.

“Duke Energy manipulates the electricity market by constructing costly and unneeded generation facilities, directly leading to generating capacity far above what is reasonable or necessary to meet demand,” NC WARN’s complaint (EL15-32) said.

NC WARN also said Duke, in “not effectively connecting” its transmission system with neighboring utilities, has not complied with Order 1000.

The group said those utilities, including Dominion Resources, Southern Co. and the Tennessee Valley Authority, also have excess reserve margins. “The excess capacity throughout the Southeast region can and should be used among the various utilities to supplement each other’s generation requirements, rather than to duplicate the waste of unneeded or underutilized generation,” the group said.

The group cited the North American Electric Reliability Corp.’s 2014 Summer Reliability Assessment, which showed reserve margins of 24% in SERC-E (the Carolinas), 26% in SERC-N (primarily TVA), 37% in SERC-SE (primarily Georgia and Alabama) and 29% in the Florida Reliability Coordinating Council.

“The resulting total for [the] Southeast is much greater than the [NERC] reference margin of 14.8%,” the group said.

Duke said in a statement that it is following a responsible building program, and that its natural gas plants are necessary, replacing older, coal-fired plants.

“The North Carolina Utilities Commission has repeatedly rejected NC WARN’s similar arguments in the past,” Duke said. “In addition, the North Carolina Public Staff — which represents customers and the public — has repeatedly supported, as reasonable, Duke Energy’s investment in power plants and electricity reserves to meet customer needs at all times.”

NC WARN asked FERC to hold hearings in Raleigh, investigate Duke’s building plans and order Duke and its neighbors to form an RTO.

FERC has repeatedly ruled that RTO membership is voluntary. However, it has pushed Duke to join with its neighbors in interregional planning under Order 1000. (See FERC Rebuff of Duke Could Mean Closer Ties with PJM.)

New York Doubles Solar Net Metering Cap to 6%

By William Opalka

New York regulators have doubled the cap on the amount of solar energy the state’s utilities are required to purchase under its net metering program.

The New York Public Service Commission ordered the increase to 6% of utilities’ peak demand from the current 3% (14-E-0151).

The commission acted in response to a request by environmentalists for an increase and a petition by Central Hudson Gas & Electric, which said it expected to reach the 3% cap in mid-2015, mostly through its residential solar programs.

The state’s 2008 Public Service Law set net metering at 1% of a utility’s peak demand, using 2005 as the base year, then gave the PSC discretion to increase the amount “in the public interest.” Central Hudson’s cap was increased to 3% in 2012 and a 2013 order raised the cap for the state’s other utilities.

Central Hudson is currently at about 83% of its 36-MW cap. National Grid is at 102% of its 196-MW cap, including projects proposed but not yet built within its service territory. As of Sept. 30, no other utility is above 63% of its cap.

The Solar Energy Industries Association, the National Resources Defense Council and other environmental groups had asked the commission to clarify the process for increasing the cap while Central Hudson had proposed increasing it to 12%.

The PSC expressed concerns about shifting costs onto ratepayers that decline or are unable to participate in a solar program. The 3% cap increases the average delivery bill of Central Hudson’s customers by about 0.5%. If all of the new net metering capacity is from solar generation, additional cost increases are expected to be from 0.5% to 1%, the PSC said.

In 2012, Gov. Andrew Cuomo announced the NY-Sun Initiative with a goal of installing 3 GW of solar power by 2023. In April 2014, Cuomo promised $1 billion for the program. Current capacity is more than 316 MW.

The new cap is effective Jan. 2. Central Hudson, Consolidated Edison, New York State Electric and Gas, National Grid, Orange & Rockland Utilities and Rochester Gas & Electric are to make compliance filings by Dec. 22.

PJM Submits Filing on Reactive Power Payments

PJM last week filed Tariff revisions in response to an order by the Federal Energy Regulatory Commission requiring it take steps to prevent fleet owners from receiving reactive power payments from retired or sold generators (EL15-15). (See Impatient FERC Orders Immediate PJM Action on Reactive Power Payments to Retired Plants.)

The revisions were filed with FERC on Dec. 15, PJM Assistant General Counsel Jim Burlew told the Markets and Reliability Committee.

The revisions dictate that at least 90 days before the deactivation or disposing of a generator, the source receiving reactive power payments submit a filing with FERC either revising its rates or explaining why it has decided not to do so.

Cuomo Bans Fracking in New York

New York Gov. Andrew Cuomo’s administration last week banned hydraulic fracturing (fracking) in the state, saying there was insufficient data to overcome concerns over the practice’s health risks.

The long-delayed decision came during a year-end cabinet meeting after the state Department of Health completed a two-year review of the controversial technique to extract natural gas from deep shale formations.

“I have considered all of the data and find significant questions and risks to public health, which as of yet are unanswered,” acting DOH Commissioner Dr. Howard Zucker said. “I think it would be reckless to proceed in New York until more authoritative research is done.”

The Marcellus Shale formation extends from West Virginia, through Pennsylvania and Ohio, to western New York.

In 2012, the Department of Environmental Conservation asked the DOH to review its draft Supplemental Generic Environmental Impact Statement for High-Volume Hydraulic Fracturing (SGEIS). Prior to the health study, the DEC had conducted its own studies dating back to 2008.

The Health Department said it found significant “uncertainties about adverse health outcomes” and inadequate mitigation measures to protect public health.

The department said several years of study are needed to determine how much risk is associated with fracking. “Until the science provides sufficient information to determine the level of risk to public health from [fracking] to all New Yorkers and whether the risks can be adequately managed, DOH recommends that [it] should not proceed,” the department said in the study.

The ban is unlikely to slow the shift to gas-fired generation in the state, however. According to the U.S. Energy Information Administration, the state generated nearly 60,000 GWh from natural gas in 2012, more than double the output in 2004.

MISO Wins Waiver on Tx Requests in SPP Seams Battle

By Chris O’Malley

The Federal Energy Regulatory Commission granted MISO’s request to suspend action on long-term transmission service requests (TSRs) between its north and south regions through April 1 as it tries to resolve a flow dispute with SPP.

The waiver (ER14-2022) also allows MISO to waive Tariff requirements and North American Energy Standards Board standards involving flows exporting from MISO South to PJM.

MISO requested the waiver through April 1, 2015, to help it address transmission constraints resulting from its dispute with SPP.

SPP alleged its joint operating agreement with MISO was breached after Entergy joined MISO last year and began transferring electricity over SPP’s lines. SPP has billed MISO more than $35 million for flows exceeding the 1,000-MW physical contact path limit between MISO North and MISO South.

MISO told the commission that the waiver request would affect 10 pending long-term firm TSRs from a single customer totaling 2,831 MW.

MISO’s waiver request provided some insight into its thinking in integrating Entergy before the dispute with SPP arose.

Originally, MISO said it anticipated that the primary restrictions on flows between its north and south regions would be set under the Operations Reliability Coordination Agreement (ORCA), a seams agreement with SPP, and that it would have extra time to negotiate seams agreements governing flows between those regions.

MISO told FERC the need for a 1,000-MW limit on flows between the north and south was a “sudden and unexpected development” and that it hopes to have alternative seams agreements in place by April 1 — the end of the operations transition period under the ORCA.

Interveners — including Southern Co., Louisville Gas & Electric and the Tennessee Valley Authority — opposed the waiver, saying it was “premature for MISO to assume that the [transition period] will not be extended” past April 1.

They said a waiver would prevent an extension of the transition period and deny their ability “to obtain much-needed reliability information on MISO’s planned flow activity.”

In approving the waiver, the commissioners said MISO “has acted in good faith with respect to the Tariff provisions for which [the] waiver is sought. The circumstances that effectively placed a 1,000-MW limit on MISO’s ability to grant additional long-term TSRs over the MISO North-MISO South interface arose relatively suddenly.”

The commission noted that transmission customers likely would be unwilling to fund construction of new upgrades to obtain service at the north-south interface given that the capacity limit is potentially a temporary situation.

MISO had argued that entities faced a difficult choice of consenting to build new capacity that later may not be needed — or losing their queue priority if they decline construction of the capacity.
