DOJ Probing Interconnection Process in Exelon-Pepco Merger

By Ted Caddell and Rich Heidorn Jr.

dojThe U.S. Department of Justice is investigating the interconnection process in PJM’s MAAC sub-region as part of its anti-trust review of Exelon’s $6.8 billion takeover of Pepco Holdings Inc.

PJM officials said last week they had received a request for documents regarding “each proposed generating facility or planned upgrade to an existing facility (300 MW and above) that filed a request with PJM to interconnect in the MAAC sub-region of PJM in the last 10 years.”

The request came just five days after the Federal Energy Regulatory Commission approved the acquisition, without discussion or conditions, at its Nov. 20 meeting (EC14-96).

The Justice Department appears to be investigating concerns previously raised by PJM’s Market Monitor, which said transmission owners may have a conflict of interest in conducting interconnection studies on competitors’ generation.

The request covers PJM and all members involved in the interconnection process. “If you are a transmission owner or generator owner in the MACC sub-region involved in generator interconnection queue requests 300 MW and above in the last 10 years, then you are an affected member,” Dave Anders, PJM director of stakeholder affairs, wrote in an email to members.

Of the more than 1,100 projects submitted in the last 10 years, about 245 of them are 300 MW or above and about 118 are in MAAC. The department wants those documents from all parties by Dec. 16.

“We’re just sending them all of our file cabinets,” joked Steve Herling, PJM vice president for planning, when asked about the request during the Planning Committee meeting last week.

Section 7 Inquiry

The Justice Department’s notice doesn’t detail why it is seeking the documents. The demand letter notes that it is seeking the documents “in the course of an antitrust investigation to determine whether there is, has been or may be a violation of Section 7 of the Clayton Act … by conduct, activities or proposed action” of the acquisition of Pepco by Exelon.

Section 7 prohibits a merger if “the effect of such acquisition may be substantially to lessen competition or to tend to create a monopoly.”

Exelon spokeswoman Judy Rader said the company has already provided the department with documents in connection with what she called “the DOJ’s review of our proposed merger, not a separate antitrust investigation.”

Interconnection Process

As in non-RTO regions, PJM’s transmission owners conduct the studies that determine what developers will need to spend to connect their generators to the grid without causing overloads or other reliability problems. PJM manages the queue process.

“The process is complex and time-consuming as a result of the nature of the required analyses. The cost, time and uncertainty associated with interconnecting to the grid may create barriers to entry for potential entrants,” the Independent Market Monitor noted in the State of the Market report for the third quarter of 2014. “The queue contains a substantial number of projects that are not likely to be built. These projects may create barriers to entry for projects that would otherwise be completed by taking up queue positions, increasing interconnection costs and creating uncertainty.”

PJM Assistant General Counsel Steve Pincus said PJM received a data request for Exelon’s acquisition of Constellation Energy. That deal closed in 2012.

This is the first time Pincus said he was aware of the department taking interest in the interconnection process.

FERC enforcement staff has investigated interconnection processes in other regions, such as the Southeast. There, independent generators complained that vertically integrated utilities outside of RTOs were using the process to thwart competition by delaying studies and requiring excessive spending on transmission upgrades.

“We think that our process, with the RTO’s independence, addresses those issues that existed in the past,” Pincus said.

IMM Still Has Concerns

Market Monitor Joe Bowring declined to comment yesterday on the department’s inquiry. But the Monitor has been recommending since 2013 that PJM outsource interconnection studies to an independent party to avoid potential conflicts of interest.

“Currently, these studies are performed by incumbent transmission owners under PJM’s direction. This creates potential conflicts of interest, particularly when transmission owners are vertically integrated and the owner of transmission also owns generation,” the Monitor said in the third-quarter report.

“There is also a potential conflict of interest when the transmission owner evaluates the interconnection requirements of new generation which is part of the same company,” the report added.

The Monitor also recommended last year that PJM establish a review process to ensure that projects are removed from the queue if they are not viable, and that commercially viable projects advance in the queue ahead of projects that have failed to make progress.

“DOJ issues these kinds of requests from time to time in large merger cases to gather more information to complete its investigation,” Rader said. “Exelon and PHI have already provided the DOJ with our documents related to this request, and now the DOJ is asking for similar information from other parties. Exelon and PHI will continue to work cooperatively with the DOJ as it conducts its review of our proposed merger.”

Not Routine

But D.C. energy attorney Carolyn Elefant, who has 25 years of experience in federal regulatory matters, sees it as anything but routine.

“It is very unusual,” Elefant said yesterday. “It does seem unusual for the Department of Justice to go right to the transmission organization, and also I am not quite sure why the Department of Justice didn’t raise these issues” with FERC, she said.

Elefant represents the Mid Atlantic Renewable Energy Coalition, one of the interveners in the Exelon-Pepco acquisition docket, but doesn’t represent any of the parties covered by the Justice Department document demand.

“I think it is fair to say that the Department of Justice either has concerns about the acquisition or concerns about FERC’s resolution,” she said.

FERC Approval

In September, FERC issued a notice that it had given permission for staff to communicate with the department.

In its Nov. 20 order, FERC indicated it did not have any anticompetitive concerns with the Pepco acquisition. (See FERC Approves Exelon-Pepco Merger.)

Dismissing concerns of market power, possible rate climbs and suppressed competition, the commission approved the pending acquisition without discussion. Its written decision made clear it didn’t see any market issues with the acquisition, in part because Pepco holds only a negligible amount of generation. “While the commission is aware that Exelon will be a member with more assets after the merger, there is nothing in the record of this proceeding to indicate Exelon will have excessive influence over the stakeholder process or the independence of PJM.”

FERC did not immediately respond to a request for comment yesterday.

What You Need to Know about PJM’s Capacity Performance Proposal

By Rich Heidorn Jr.

PJM’s Board of Managers will file a proposal this week with the Federal Energy Regulatory Commission to increase the reliability expectations of capacity resources with a “no excuses” policy that would result in larger capacity payments and higher penalties for non-performance.

The proposal will be the third revision of a plan PJM staff unveiled Aug. 20 (see PJM: New Capacity Product Needed for Reliability) and revised Oct. 7 (see Lower Penalties, More Flexibility in Revised PJM Capacity Performance Proposal).

It includes a more gradual transition into the proposed new market design and increased benefits for high-performing generators than staff’s Oct. 7 proposal. The board’s changes are intended to blunt criticism that PJM’s plan was overly expensive and being implemented too quickly.

The proposal borrows heavily from ISO-NE’s “pay-for-performance” design, which won FERC approval earlier this year. PJM officials are hopeful that the eight changes made by the board in the proposal announced last week will blunt most of the criticism.

The changes would begin to take effect for the 2016/17 delivery year with full implementation in 2020/21.

What is PJM Proposing?

The proposal includes a new product called “Capacity Performance,” which would replace the current product (renamed Base Capacity). Resources that clear the capacity auction would be required to deliver energy when scheduled and dispatched by PJM during “compliance hours,” defined as any emergency procedure event requiring implementation of demand response or the loading of emergency capacity.

Each Capacity Performance resource must offer into the day-ahead energy market and be available for at least 700 hours of non-emergency operation in the delivery year.

PJM is proposing a “no excuses” approach similar to ISO-NE’s that eliminates “out-of-management control” exemptions.

The increased risks and rewards are intended to incent generators to introduce dual-fuel capability or sign firm natural gas delivery contracts to minimize their fuel delivery risk.

Intermittent and seasonal resources could satisfy Capacity Performance requirements with “coupled offers” in which they share the responsibility with one or more other resources.

Offer parameters would be limited to physical resource limits. During Hot or Cold Weather Alerts, resource notification time would be limited to one hour.

All resources must take steps to ensure they are available for scheduling with no more than a 14-hour lead time.

Performance Obligation – Each resource is required to deliver its pro-rata share of system requirements during Compliance Hours. The resource’s pro-rata share is calculated during Compliance Hours as the lesser of the resource’s cleared capacity megawatt quantity times the ratio of real-time demand plus reserves divided by PJM’s total quantity of cleared capacity megawatts and the resource’s economic dispatch point, net of any PJM-approved outages.

What Happens to Resources that Fail to Perform?

A resource that fails to deliver its full obligation will be assessed a penalty (“Performance Payment”) equal to the shortfall (in megawatts) multiplied by the performance payment rate.

Performance Payment Rate – The Performance Payment Rate is the Net Cost of New Entry (in $/MW-year) multiplied by the number of days per year and divided by the expected number of Compliance Hours per year.

Annual penalties would be limited to 1.5 times net cost of new entry, multiplied by the resource’s committed megawatts, multiplied by the number of days per year. Monthly penalties would be limited to the annual stop-loss divided by three.

Penalties collected from under-performing resources would be allocated pro-rata to all over-performing resources in the hour, including energy-only resources that perform during compliance hours. Performance payments would not be assessed during non-emergency hours.

Generation owners with multiple plants can avoid penalties by providing energy from non-capacity resources.

How much will it Cost?

PJM says the increased performance will result in increased monthly capacity costs of about $2 to $3 per household beginning in 2018, assuming average winter and summer weather. In a year of extreme weather, officials say, it would result in net savings because the increased capacity costs will be more than offset by reduced energy costs. The program would have saved $7 billion in 2014, according to a PJM simulation.

Andy Ott, executive vice president for markets, noted that only 10% of total billings are for capacity, while 80% is energy. “Even a modest change in the energy price will offset the capacity price” increase, he said during a press conference last week.

PJM would allocate costs to load based on total compliance hours for the year and the five coincident-peak hours. The current cost allocation is based on the current five-coincident-peaks alone. The cost allocation is based on actual, measured loads.

The offer cap for Capacity Performance product offers is equal to the net CONE. If a resource desires to offer above the net CONE, its offer is subject to cost-based-offer review per the current processes if it fails the three pivotal supplier tests.

When Will it Take Effect?

PJM hopes to receive FERC’s OK in time to begin implementing changes in May’s Base Residual Auction for delivery year 2018/19. (On Nov. 28, FERC approved changes to the capacity market parameters for the May auction with minimal changes. (ER14-2940))

PJM plans to procure an additional 2,500 MW of Base Capacity for winter 2015/16 and begin soliciting Capacity Performance resources for delivery year 2016/17 (60% of total capacity) and 2017/18 (70%) through incremental auctions. Capacity Performance will be acquired through the Base Residual Auction beginning with delivery years 2018/19 (80%) and 2019/20 (80%). Capacity Performance would be 100% of resources starting with delivery year 2020/21. (See table.)

What Happens to Demand Response?

The Capacity Performance plan does not include PJM’s proposal to eliminate demand response as a supply resource. The DR proposal, outlined in an Oct. 7 white paper, would make load-serving entities responsible for incorporating DR in reduced demand estimates. (See PJM DR Cos. Confident; Reject PJM EPSA Response.)

CEO Terry Boston said PJM should delay changes in its DR rules pending the resolution of a potential Supreme Court review of the D.C. Circuit Court of Appeals’ Electric Power Supply Association ruling voiding federal jurisdiction over DR compensation. (See related story, U.S. to Seek Supreme Court Review of EPSA Ruling.)

What has been the Reaction from Stakeholders?

RTO Insider requested comment on the plan from the spokespeople for the 15 coalitions that met with the Board in November.

EnergyConnect’s Bruce Campbell, representing the Advanced Energy Management Alliance, said PJM has not allowed adequate stakeholder review for what is a “substantial redefinition of capacity.”

“We anticipate significant unintended consequences as well as substantial increased costs with no particular promise of increased reliability,” Campbell said. “We are disappointed that what should have been a measured response to poor generator performance during last winter’s polar vortex events has evolved into a major reworking of PJM’s capacity market.”

The alliance said PJM should have proposed “more focused penalties for generator non-performance during actual emergencies similar to those demand resources have always accepted.”

Other coalitions either did not respond or said they needed more time to analyze the proposal.

Rest assured, they’ll have plenty to tell FERC.

Generators: EPA Clean Power Plan Interim Goals Unrealistic

By Michael Brooks

Utilities and independent power producers said the Environmental Protection Agency should delay or eliminate the interim goals in its proposed carbon emission plan.

The EPA’s plan calls for a two-part goal structure for each state: an “interim” average goal over 10 years beginning in 2020, and a final goal that must be met by 2030.

Some companies and trade groups, while supportive of the general effort to reduce greenhouse gas emissions, criticized the goal schedule as inflexible. The plan calls for the majority of the overall cuts in its first years, forcing states to make decisions without “thoughtful implementation,” NRG Energy said in its comments.

“The EPA’s proposed rule provides great flexibility for how states can achieve the required CO2 reductions,” NRG said. “However, it offers hardly any flexibility on when to achieve them.”

The company said this would create the unintended consequence of hastily built natural gas plants as states struggle to quickly meet the interim average, lowering emissions but deepening the country’s dependence on fossil fuels and making it difficult for renewable sources to break into the mix.

The Edison Electric Institute, which represents investor-owned utilities, echoed NRG’s criticism.

“In order to satisfy the 10-year average goal, many states must achieve more than 50% of their 2030 emission-reduction goals by 2020; and 11 states — including Arizona, Arkansas, Florida and Minnesota — must achieve more than 75% of their 2030 goals by 2020,” the association said. “This effectively turns the 2030 goal into a 2020 goal for these states.”

“There is not sufficient time between now and 2020 for utilities and states to develop, plan, design and complete the infrastructure required to meet the interim goals as proposed,” EEI president Tom Kuhn said in a statement.

NRG suggested the EPA maintain its “strong” 2030 goal, but that the agency allow states to move toward that goal at their own pace.

Alternatively, the company suggested modifying the interim goal “so that states must meet one-half of the interim goal, on average, in each of the 10 years from 2020 to 2029, while also meeting the 2030 goal. This would allow each state to set a straight diagonal line glide path from 2020 to 2030, or a number of other trajectories that might better suit the state — including dramatic early reductions in any state that deems them prudent.”

Dominion Resources, while also signaling its support for reducing emissions, also urged the EPA to eliminate the 2020 interim goal but suggested allowing states to meet an interim 2025 target before fulfilling its 2030 obligations.

EEI, while questioning the plan’s legality, echoed these suggestions. “Eliminating the interim compliance goal and allowing states to determine their own reduction glide paths and milestones to achieve the 2030, or the early-action alternative 2025, goals as part of their compliance plans would provide states with real flexibility to preserve reliability and minimize costs to electricity customers.”

Regional Approach rather than State-by-State

Companies and groups also criticized the use of state boundaries as a means of setting compliance targets, noting that many utility service territories and RTO and NERC regions do not coincide with state lines.

EEI questioned the legality of state-wide goals.

“Nothing in section 111(d) [of the Clean Air Act] clearly authorizes EPA to set emission goals based upon a large, heterogeneous set of units aggregated across a state,” the EEI said. “Instead, for EPA to regulate CO2 emissions (or emissions of any other type of pollutant) from existing sources, the regulations should be based on the sources themselves — and on a standard of performance attainable by implementing measures at those sources — rather than an aggregation of sources that happen to be within a particular state.”

EPA: More than 1.6M Comments in Response to Clean Power Plan

Janet McCabe, acting assistant administrator for the Environmental Protection Agency’s Office of Air and Radiation, said last week that the agency had met with more than 300 groups and received more than 1.6 million comments since releasing its proposed carbon emission rule in June. Here are a few samples.

Aluminum-maker Alcoa said states should be allowed to take into account the “measurable and verifiable” carbon reductions made by utilities and industrial power generators since 2005.

Alcoa points to its massive plant in Newburgh, Ind., where it installed more efficient turbines and sulfur scrubbers in the early 2000s.

Making additional improvements to energy efficiency would be cost-prohibitive today, Alcoa said. Thus, the company said the EPA should identify which existing units in the state have no cost-effective options to achieve a 6% unit heat rate improvement under building block 1.

“This correction also should be applied to the proposed CO2 standards for other states where heat rate improvements have already been implemented on the existing utility boilers,” said Michael Padgett, vice president of energy and carbon strategy at Alcoa.

Federal Energy Regulatory Commissioner Philip Moeller said market forces have already reduced greenhouse gas emissions by 10% below 2005 levels. But he said the EPA’s proposed rule “will dramatically interfere with America’s competitive market forces, perhaps resulting in even more greenhouse gases in the future.”

The EPA plan “seems to assume that a significant amount of new natural gas pipelines needed to fuel power plants, along with a similarly significant expansion of the nation’s electric transmission system will suddenly appear so as to meet the new demands,” Moeller continued. “Such an assumption ignores the very real challenges we currently have in expanding these categories of energy infrastructure.”

The Kentucky Chamber of Commerce was among the critics asserting that the EPA lacks legal authority for the proposed rule, which the agency plans to administer under section 111(d) of the Clean Air Act.

“The statutory language of Section 111(d) is the result of differing House and Senate versions of the language that were never reconciled in conference, but instead, were both signed into law. The House version prohibits existing sources from being regulated under Section 111(d) if those sources are already regulated under Section 112. The Senate version provides that unless a particular air pollutant emitted by an existing source is regulated by one of the other listed Clean Air Act provisions (e.g., Section 112), existing sources emitting that pollutant could be regulated under Section 111(d). Because the Senate version was classified as a conforming amendment and conforming amendments are considered procedural in nature, the House amendment controls.”

The Ohio Environmental Protection Agency said the EPA’s cost analysis is “flawed and radically underestimates the projected cost of electricity from this proposal.”

The American Coalition for Clean Coal Electricity said the EPA’s proposal “is based on flawed data and sets a dangerous legal and regulatory precedent that puts America’s energy and economic future in jeopardy. The problems associated with this legally questionable proposal are manifold and will result in needless harm to Americans’ pocketbooks and our economy at large.”

The Nuclear Energy Institute, which noted that nuclear power produces about two-thirds of all carbon-free electricity in the U.S., called the plan “fundamentally flawed.”

“EPA’s proposed rule … recognizes the importance of nuclear energy in reducing electric sector carbon emissions and attempts to create an incentive for states to preserve existing nuclear generating capacity. As proposed, however, the rule does not achieve that objective. In addition, the proposed rule creates a significant, inappropriate and inequitable penalty for Georgia, South Carolina and Tennessee, where new reactors are being built.”

The Natural Resources Defense Council said the EPA can achieve substantially deeper cuts in carbon emissions by accelerating the use of energy efficiency and renewable power. “The administration can make this good plan even better,” said David Doniger, director of NRDC’s Climate and Clean Air Program.

RGGI: EPA ‘Building Blocks’ May Overlook Progress of Early-Action States

By William Opalka

The Regional Greenhouse Gas Initiative did most of the talking for states in the Northeast about the Environmental Protection Agency’s Clean Power Plan, as ISO-NE declined to file its own comments, instead signing on to those of the ISO/RTO Council.

RGGI, which established a carbon-reduction market with proceeds to benefit renewable energy and energy-efficiency programs, generally supported the EPA plan and suggested other areas of the country could follow its lead.

RGGI’s comments were signed by the utility regulators of its member states: Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, New York, Delaware and Maryland.

The officials praised the EPA for recognizing RGGI as an acceptable compliance mechanism incorporating many of their recommendations into the proposal.

But the officials said the plan “may not adequately recognize the substantial progress already made by early-action states,” such as those in RGGI. They said it would be unfair for the agency to require early adopters to make the same kind of additional emission reductions as the states that did little or nothing.

RGGI states have already achieved a 40% reduction in regional carbon emissions from the electricity sector from 2005 levels, the states said.

The comments were intended as a group statement, with states able to provide additional observations.

Connecticut Department of Energy and Environmental Protection Commissioner Robert Klee responded to the EPA’s request for comments on using 2012 as the base year for reductions instead of 2005. He supported the later baseline.

“Between 2005 and 2012, we reduced gross CO2 emissions from the power sector by 23% and per capita emissions by 25%,” he wrote.

PJM: EPA Clean Power Plan Should Include Reliability ‘Safety Valve’

By Suzanne Herel and Rich Heidorn Jr.

Like the ISO/RTO Council, PJM called for a reliability “safety valve” in the Environmental Protection Agency’s proposed Clean Power Plan to ensure that the final rule and state implementation plans include provisions for minimizing reliability impacts on the grid.

The idea is similar to a provision included in the agency’s mercury and air toxics standards (MATS). Such a safety valve might allow delaying a plant’s retirement until transmission upgrades can be completed.

PJM said its recommendations aim to ensure “overall reliability of the bulk power system” and promote regional coordination in grid operations while also respecting states’ rights to establish individual plans.

PJM also said EPA should:

  • Change aspects of the proposed rule that discourage regional coordination on implementation;
  • Include a measure to encourage coordination and consistency of compliance measurement and verification protocols;
  • Propose an approach for flexibility in the determination of “at-risk” nuclear units in a state; and
  • Clarify the term “under construction” in the EPA target-setting. PJM suggested that the term be tied to readily identified benchmarks.

The council also called on the EPA to expand its “glide path” flexibility proposal to allow for construction of gas pipelines and new electric system infrastructure.

PJM said the rule leaves little leeway for conditions arising during the 2020-2029 compliance period.

It suggested “case-by-case relief” in addressing a demonstrated reliability issue. That would allow a state or region to adopt a less strict averaging requirement if it met the 2030 compliance target and took affirmative steps to address the identified reliability issues.

PJM also proposed relief based on “triggering events” to allow for exceptions to meeting the state-specific average interim target.

In addition, it noted that the proposed rule does not define the term “backsliding.”

“Technically, retaining generators otherwise slated for retirement through ‘Reliability Must Run’ contracts, although limited and justified only for local reliability needs, could well be deemed ‘backsliding’ and thus in violation,” PJM said, noting that RTOs and federal and state regulators often are faced with making spot decisions on whether to allow a generator to run in this manner.

NYISO: EPA Clean Power Plan Threatens Reliability for New York City

By William Opalka

The Environmental Protection Agency’s proposed Clean Power Plan threatens system reliability in New York City due to the city’s frequent dependence on local oil-fueled generators, NYISO said.

NYISO also said the plan fails to recognize significant progress that New York state has already made in reducing CO2 emissions.

But the majority of its comments filed with the EPA highlighted the unique circumstances of the largest city in the United States: a densely populated area with inadequate transmission capacity to move electricity from other regions of the state, forcing it to rely on smaller units within city limits that are often fueled by oil.

“A majority of the electric capacity within New York City is dual-fuel oil/gas steam-fired electric generating units. These units are critically important, both due to their location within the transmission constrained New York City area and because they possess dual-fuel capability that provides a needed measure of protection against disruptions in the natural gas supply system,” NYISO said in comments filed with the EPA.

The units run principally on natural gas but can switch to oil when supplies are constrained. That dual capability was crucial last winter when natural gas supplies in the Northeast became constrained during the worst cold snaps.

Building Blocks

NYISO said the so-called “building blocks” in the EPA’s plan wrongly assume that output from these facilities could be reduced by more than 99%. Reliability would be compromised under the timeline contemplated by the plan, according to NYISO.

NYISO’s recommendations include:

  • A review of reliability impacts using a preliminary assessment already done by the North American Electric Reliability Corp. The Federal Energy Regulatory Commission also should be involved in this review to assess both the reliability and other issues that fall within its jurisdiction.
  • Formalization of a reliability “safety valve” by which the implementation of a state plan could be adjusted, with new time frames that may be caused by unforeseen circumstances.
  • Adjustments to the building blocks to produce a target that accurately reflects how power is generated, transmitted and used in New York. This would include elimination of the heat-rate improvements assumed in building block 1.
  • EPA adoption of a rate-to-mass conversion method that supports regional efforts, like the Regional Greenhouse Gas Initiative, that harness market forces.

The grid operator also said New York has not been given credit for emissions reductions already achieved or for its plans to further reduce carbon emissions.

“New York has already reduced CO2 emissions from its power sector by 41.6% below 2005 levels and generates approximately 53% of the electricity it uses on an annual basis from non-emitting resources,” NYISO said.

Its commitment under the nine-state Regional Greenhouse Gas Initiative calls for further carbon reductions by 2020.

MISO, SPP: EPA Clean Power Plan Threatens Reliability, Needs Longer Compliance Schedule

By Chris O’Malley

SPP and MISO warned of a reliability crisis if the Environmental Protection Agency’s proposed Clean Power Plan isn’t eased to account for up to 134 GW of generation retirements by 2020, most of them coal-fired units.

“Unless the proposed CPP is modified significantly, SPP’s transmission system impact evaluation indicates serious, detrimental impacts on the reliable operation of the bulk electric system … introducing the very real possibility of rolling blackouts or cascading outages that will have significant impacts on human health, public safety and economic activity,” SPP CEO Nicholas Brown said in his comment to the EPA.

SPP said it conducted a study that assumed new generation was added without additional transmission infrastructure. The model showed that portions of the system in the Texas panhandle, western Kansas and northern Arkansas “were so severely overloaded that cascading outages and voltage collapse would occur and would result in violations of [North American Electric Reliability Corp.] reliability standards,” Brown said.

NERC has expressed similar concerns, commenting that “developing suitable replacement generation resources to maintain adequate reserve margin levels may represent a significant reliability challenge, given the constrained time period for implementation.”

NERC’s 2014 Long Term Reliability Assessment said that plant retirements and limited capacity additions are contributing to diminishing reserve margins in the Midwest, New York and Texas.

SPP said its reserve margins, now at 13.6% above peak demand, would fall to 4.7%, or a reserve margin deficiency of about 4,600 MW, by 2020.

MISO: ‘Untenable and Infeasible’

MISO proposed that the EPA eliminate the interim 2020 performance requirements because the organization’s initial analysis of the rule shows that nearly 80% of total emissions reductions must be met by then.

The EPA’s performance requirements create “an untenable and infeasible timeline for reliable compliance, and would cause states and MISO member companies to make decisions on a severely truncated timeline,” MISO CEO John Bear warned.

Bear said it will take more time to build new generation, natural gas pipelines and other necessary facilities than the interim period allows. Bear pointed to MISO’s Multi Value Projects, which were driven by state public policy requirements such as renewable energy.

The MVP portfolio took five years of planning and shareholder discussion, and even now many of the projects are in development, regulatory and construction phases, he said.

Bear said the soonest a state compliance plan could be approved is 2017, adding that it may not be until 2019 that some states iron out a compliance strategy.

“Since action will be needed by 2020 to achieve the interim emissions performance levels, there will not be nearly enough time to plan for the replacement capacity, transmission upgrades and natural gas delivery infrastructure that will be required to maintain reliability and resource adequacy,” he said.

MISO asked the EPA to push back its proposed carbon dioxide reduction requirements, estimating that 11 GW of plant retirements in its region would need to occur in 2020, “well before sufficient replacement capacity can be placed into service.”

Bear warned that MISO’s planning reserve margin is already under pressure because 10 to 12 GW of coal-fired generation capacity will retire by 2016 to meet the agency’s Mercury and Air Toxics Standards (MATS).

The erosion of the reserve margin increases the likelihood that MISO will need to manage periods of high demand with “emergency operation procedures,” Bear said. “The probability of a loss-of-load event becomes greater than the MISO region has ever experienced.”

Under the “best circumstances,” new generation capacity would not be available until 2024, Bear told the EPA.

Technical Conference Sought

SPP seeks a series of technical conferences jointly sponsored by the EPA and the Federal Energy Regulatory Commission that would focus on the plan’s effects on regional markets and power system reliability. It wants NERC to conduct a “detailed, comprehensive and independent” study of the North American bulk power system, prior to the agency adopting its final rule.

SPP also wants to see the CPP compliance schedule extended by at least five years.

Some commenters, including the Kansas Corporation Commission, told the EPA that the plan is “extremely flawed” and requested that it be withdrawn for a system of emissions reduction that is less complicated and ensures reliability at a reasonable cost.

The KCC said Kansas has approved more than $3 billion of environmental compliance projects for coal-fired generating plants. “To avoid stranded ratepayer investment, specific coal-fired units that were retrofit in compliance with EPA rules should be excluded from the EPA’s calculations in determining a CO2 emissions goal.”

RTOs Raise Concerns over Reliability, Schedule in EPA Clean Power Plan

PJM, MISO, SPP and NYISO joined a chorus of critics last week in warning that the Environmental Protection Agency’s proposed carbon emission rule threatens grid reliability, saying the agency should provide more time to build the generation, transmission and natural gas pipelines needed to comply.

At the same time, officials in New England and elsewhere complained that the EPA’s Clean Power Plan does not give enough credit for carbon emission reductions that have already been accomplished.

The critiques were among more than 1.6 million comments filed with the EPA before a Dec. 1 deadline.

SPP warned of rolling blackouts while NYISO said the plan ignored New York City’s reliance on oil-fired generation. PJM, MISO, NYISO and the ISO/RTO Council called on the agency to add a reliability “safety valve.”

Sen. Lisa Murkowski (R-Alaska), who will likely become chairman of the Senate Energy and Natural Resources Committee under a Republican majority next year, and House Energy and Commerce Committee Chairman Fred Upton (R-Mich.) last month called on the Federal Energy Regulatory Commission to convene a technical conference to address reliability concerns.

Some congressional Republicans have threatened to use oversight hearings and appropriations bills to blunt the rule. But lacking a veto-proof majority, the GOP is unlikely to block President Obama’s signature environmental initiative. (See GOP Election Victories Unlikely to Thwart EPA Carbon Plan.)

The proposed rule would require states to devise plans to cut existing power plant carbon emissions from 2005 levels by 30% by 2030, with intermediate goals along the way.

The EPA signaled in October that the final rule, due in June 2015, may relax the interim targets. (See EPA Signals Flexibility on Interim Carbon Targets, Coal-Gas Shift.)

PJM Board Releases Capacity Performance Proposal

By Rich Heidorn Jr.

PJM’s Board of Managers today announced a final Capacity Performance plan that includes a more gradual transition into the new market design and increased benefits for high-performing generators than staff’s Oct. 7 proposal.

The board’s proposal will be submitted next week for Federal Energy Regulatory Commission approval. PJM hopes to receive FERC’s OK in time to begin implementing changes in May’s Base Residual Auction for delivery year 2018/19.

The board’s changes are intended to blunt criticism that PJM’s plan was overly expensive and being implemented too quickly. On Oct. 28, 14 coalitions representing more than 80 stakeholders submitted their critiques via briefing papers to the board. Eight of the groups generally opposed the proposal while six were generally supportive. (See Coalitions Make Their Cases to PJM Board.)

In a late afternoon press conference today, Executive Vice President for Markets Andy Ott said the changes would provide an “insurance policy” at a cost of about $2 to $3 per month per household when it is implemented in 2018.

“Many of the issues raised during this five-month discussion of Capacity Performance are not unique to the PJM region,” PJM CEO Terry Boston said in a letter to stakeholders outlining the board’s revisions. “PJM is modeling its approach after the ‘Pay for Performance’ capacity market design that FERC recently approved for ISO-NE, along with changes in the transition period that allow time for market participants to adapt and to lessen cost impacts. This design also allows for greater opportunities for all resources to participate in this enhanced capacity market.”

Changes Detailed

The board made the following eight changes to PJM staff’s Oct. 7 proposal, saying it would “improve the balance between the cost of infrastructure improvements and the benefits of reliability”:

  1. Revises the performance requirement, incentive and payment structure to one similar to that approved by FERC for ISO-NE.

 

Penalties (or “performance payments”) from under-performing resources will be allocated to over-performing generators, including energy-only resources that provide energy during emergencies. The change will allow intermittent resources and non-capacity resources to earn additional revenue.

 

  1. Adopts a “no excuses” approach to performance requirements except for retention of the exemption for resources following PJM scheduling and dispatch instructions.

 

PJM says this will ensure generators invest in maintenance and fuel security — such as obtaining dual-fuel capability — to avoid penalties. “This approach appropriately assigns performance risk to capacity suppliers who are in the best position to manage the risk,” PJM said.

 

  1. Reduces the volumes and capabilities of capacity to be procured during the 2015-2018 transition period.

 

“This will reduce transition costs but still maintain reliability through the transition period,” PJM said.

 

  1. Expands opportunities for intermittent resources by allowing them to submit “coupled” resource offers.

 

  1. Eliminates the multi-year pricing mechanism.

 

The board said it made the change based on concerns that the mechanism — intended to reduce risk for multi-year investments in the single-year market structure — could result in “pricing anomalies and perverse incentives.” The board said the issue would be addressed separately.

 

  1. Modifies cost allocation for Capacity Performance to include all “compliance hours,” defined as any period when PJM implements emergency procedures requiring implementation of demand response or the loading of emergency capacity.

 

PJM said the change, based on discussions with its Independent Market Monitor, would maximize market efficiency and encourage year-round DR.

 

  1. Maintains DR as a supply-side resource, for now.

 

PJM said it will address uncertainties over DR’s role in wholesale markets — the result of an appellate court ruling voiding federal jurisdiction over DR compensation — in a separate proceeding.

 

Ultimately, DR would be adapted to become a peak shaving commitment, modeled on the load side.

 

Limited DR would be eliminated; annual DR would be converted to a Capacity Performance product, and summer DR would be treated as Base Capacity during the transition period.

  1. Promises to adjust the forward load forecast to address concerns that overly bullish demand predictions had caused the RTO to procure more capacity than needed, at additional cost to consumers.

 

The promise is part of the proposal to eliminate the short-term resource procurement target, a 2.5% “holdback,” which the Market Monitor says can result in price distortions.

 

By recognizing the “recent trends and impacts of energy efficiency,” the 2.5% holdback will no longer be necessary, PJM said.

Transitional Period

The board acknowledged stakeholder concerns that it might not be possible to begin requiring enhanced performance for winter 2015/2016 due to the short time available for investment in winterization, dual-fuel capability and firm-fuel contracts.

Instead, it said it would seek to procure up to 2,500 MW of additional “base” capacity — the current product definition — for December 2015 through March 2016.

For the 2016/17 delivery year, PJM proposes an auction to procure a “transitional version” of the Capacity Performance product with lower prices and nonperformance penalties than when the transition is complete. “If a resource that already has [a capacity] commitment for the delivery year clears as Capacity Performance, the Capacity Performance commitment replaces its previous commitment,” PJM said.

This transitional version of the product would make up 60% of total capacity. For the 2017/18 delivery year, Capacity Performance would increase to 70%, while in 2018/19 and 2019/20, PJM proposes 80% of total capacity be fulfilled by the new product.

Beginning in 2020/2021, all capacity would be obtained under the Capacity Performance rules.

“During the transition, Base Capacity would retain the same rules as the current annual capacity product except that the peak performance penalty structure would replace the peak forced outage metric that is currently used,” PJM said.
