PJM, NYISO Tout New Option to Improve Power Scheduling

PJM members will be asked tomorrow to approve a new scheduling option for transactions into the New York ISO to reduce uneconomic power flows.

Under the current system, PJM’s Stan Williams told the Markets and Reliability Committee Thursday, power often flows from PJM into New York even when PJM’s prices are higher.

To improve the alignment of energy scheduling with interface prices, PJM and NYISO are proposing creation of an additional product that would allow participants to submit “price differential” bids that would clear when prices in New York exceed those in PJM above a threshold set by the bidder.

The Coordinated Transaction Scheduling (CTS) proposal will be brought to a vote at the next MRC meeting if it is approved at tomorrow’s Market Implementation Committee meeting.

PJM says the new product should increase forward price transparency and price convergence between PJM and NYISO.

A cost benefit analysis found that the change would have reduced total production costs in the two RTOs by as much as $26 million in 2012. PJM officials said they had not calculated how much the savings would have been reduced by generator make whole payments resulting from the change.

The biggest opportunities for savings will come when the price differential between the two RTOs is relatively low. Analysis showed prices could be reduced in about half the hours when the price difference is $5/MWh but only 13% of the hours when the difference is $15.

CTS Interface bids would be scheduled based on the projected price difference between PJM and NYISO at the interface. It would use PJM’s Intermediate Term Security Constrained Economic Dispatch (IT SCED) application, which has a two hour look-ahead capability.

The application correctly predicted prices about 60% of the time when the price differential is $5 or less. Williams acknowledged the tool was much less reliable when the price differential is higher. Williams said PJM plans to begin posting the forecasts publicly next spring and is attempting to improve its accuracy.

Bob O’Connell, vice president and compliance manager for J.P. Morgan Ventures Energy Corp., said members shouldn’t vote on the proposal until they have evaluated the risks of relying on the forecasting tool.

He also said the changes could increase balancing congestion, which would penalize Financial Transmission Rights holders. “FTR holders get no benefit from CTS,” he said.

Williams said the changes shouldn’t hurt FTR holders and should reduce price volatility.

CTS Interface Bids would have as many as four bid curves and up to 11 $/MW pairs. The option would be in addition to current hourly evaluations of traditional wheel-through transactions and intra-hour evaluations of traditional LMP bids and offers.

Credit requirements on the new scheduling option would be based on the higher of the 97th percentile historical (prior year) hourly price for the node or the 15-minute IT SCED price forecast for the node.

The issue has been under discussion with NYISO since November 2012. The new scheduling product would require approval of the Federal Energy Regulatory Commission.

Maryland County to Challenge PEPCO Rate Hike

Isiah Leggett, chief executive of Montgomery County, MD, said last week the county will appeal the Maryland Public Service Commission’s decision awarding Potomac Electric Power Co. (Pepco) a $28 million increase in distribution rates and a $24 million surcharge to accelerate the hardening of feeder lines.

Leggett said that the PSC’s decision to approve the surcharge was “premature.”

“I believe that Pepco has made improvements in their communications, infrastructure, and emergency response systems since last summer’s ‘Derecho’ storm. However, just how improved these changes are have not yet been seriously tested,” Leggett told The Washington Post.

Leggett, who is seeking his third term as county executive, will face off against his predecessor, Douglas Duncan, and County Councilman Phil Andrews in next June’s Democratic primary.

Andrews has criticized Leggett for a series of tax hikes, including a 2010 increase in the county’s energy tax that increased household electric bills by about $139 annually.

The surcharge and base rate increase approved by the PSC will boost average residential bills by about $26 per year. (See MD OKs $28 Million Base Rate Boost for PEPCO.)

New Rules for Wind Lost Opportunity Costs

Wind farms that fail to follow PJM’s electronic dispatch signals will no longer receive lost opportunity cost payments under a tariff amendment approved by the MRC.

Reason for change: Some wind generators are not following their economic basepoint, requiring PJM to issue manual dispatch instructions. This delays generators’ responses, causing less efficient market operations and a potential risk to system reliability, PJM says.

PJM proposed the new language as a Tariff change in response to a May 29 Federal Energy Regulatory Commission order that rejected its earlier proposal to incorporate the new rules in the Operating Agreement. The commission said the OA language “failed to provide any detail or tariff language describing the specific circumstances under which compensation would be reduced or how the compensation would be reduced.”

Impact: Would add language to section 3.2.3 of Tariff Schedule 1 to deny lost opportunity credits to pool-scheduled or self-scheduled wind generators that fail to follow PJM dispatchers’ electronic instructions to reduce output. (See PJM to Tighten Penalties on Wayward Wind.)

New Process for Exceptions to Generator Parameters

PJM would add new processes for generators seeking exemptions from operating parameters under changes presented to the Markets and Reliability Committee Thursday.

PJM’s generation parameters set defaults for different types and sizes of generators. The parameters cover minimum run and down times, maximum daily and weekly starts and turn down ratios (Eco Max/Eco Min).

They were initiated in 2008 to ensure lower make whole payments for generators whose entire offers were not covered by Locational Marginal Pricing revenues.

The proposed change, the result of a year-long effort between PJM and the Market Monitor, would create three types of exemptions:

  • Temporary Exception: A one-time exception of 30 days or less.
  • Period Exception: An exception lasting for at least 31 days but no more than one year during the 12 months between June 1 and May 31.
  • Persistent Exception: An exception lasting for at least one year.

MRC will be asked to approve the changes at its next meeting.

Earlier Deadline for Plant Retirement Notices Approved

A modified proposal to set earlier deadlines for power plants seeking exemptions from participation in PJM’s capacity market auctions won approval from the Markets and Reliability and Members committees Thursday.

The current rules require 120 days’ notice before the opening of the auction.

Stu Bresler, PJM vice president of market operations, said that’s not enough time for PJM to analyze the impact of plant retirements on system operations and determine whether the RTO needs transmission upgrades to ensure reliability.

Andy Ott, executive vice president for markets, said the changes also will give market participants more information in advance of the auctions.

The change will require generators seeking exemption from the “must-offer” requirement to file notice by Sept. 1 for the annual base residual auction (BRA) and 120 days before incremental auctions. The exemptions apply to generators that will be unable to provide capacity because they plan to retire.

At July’s MRC meeting, generators said the policy change could cause staffing problems and financial burdens at generators that will be forced to announce retirements earlier. (Generators Balk as PJM Seeks Earlier Notice on Plant Retirements.)

In response, PJM and the Market Monitor changed the proposal to provide generators more flexibility and to mask the identities of individual power plants:

  • Retirement requests must be made by September 1 but can be based on a conditional deactivation analysis. The submission would specify the conditions that are creating uncertainty, such as pending negotiations on fuel or labor contracts. The finalized deactivation plan would be required by December 1 unless the request is withdrawn.
  • PJM will post information on pending plant retirements in the first week of September but will do so using zonal aggregation rather than identifying individual generators. For each transmission zone, PJM will specify the amount of capacity scheduled to retire within one of the following ranges:
    • Less than 100 MW
    • 100 MW to 500 MW
    • 500 MW to 1000 MW
    • Total capacity to be retired will be specified if a zonal total exceeds 1,000 MW.

The revised proposal was approved by a 4.11-0.89 sector-weighted vote in the MRC, with support from six generators. Five generators voted no and three abstained. The Members Committee approved it 4.35-0.65.

John Horstmann, director of RTO affairs for Dayton Power & Light Co., supported the modified proposal, saying the changes made the proposal “a lot less onerous” for generation owner. But he said the earlier deadlines don’t apply to about 20,000 MW of demand response, energy efficiency and imported generation capacity, giving them a competitive advantage. “It’s a free option,” he said.

“We’re aware of that,” Bresler responded, saying PJM would consider the issue in the future.

Neal Fitch, representing NRG Energy, also praised PJM’s revisions to the proposal but said it was still an “overcorrection.”

Susan Bruce, representing the PJM Industrial Customer Coalition, spoke in support. “It’s an important step to help the market operate efficiently,” she said.

VA OKs Dominion Virginia Power Generator

Virginia regulators last week approved Dominion Virginia Power’s request to build a 1,358 MW natural gas-fired generator near Lawrenceville in Brunswick County.

Dominion said it plans to start construction immediately on the $1.3 billion combined cycle plant, which is expected to go into commercial operation in the summer of 2016.

The Virginia State Corporation Commission approved a Certificate of Public Convenience and Necessity for the project and a rate adjustment clause to recover construction costs. The commission also approved the construction of a 13.5-mile 500 kv transmission line to connect the generator to the grid.

The rate rider will generate $43.5 million in its first year, increasing the monthly bill of a residential customer using 1,000 kilowatt-hours of electricity by 81 cents.

Dominion said the plant, which is being added to serve load growth and replace retiring coal plants, will save $96 million in fuel costs in its first full year of operation.

PJM Abandons Long-term Capacity Effort

PJM members Thursday abandoned a year-long effort to establish a long-term capacity product.

The Markets and Reliability Committee voted to strip development of a “Long-Term Capacity Auction or alternative multi-year mechanism” from the revised charter for the Capacity Senior Task Force.

“We feel that we’ve spent more than enough time on this issue,” said Bill Schofield, representing the PJM Public Power Coalition.

The committee initially rejected the proposed charter, which listed five issues, including two newest problem statements approved in May and June, by a 2.33-2.67 sector-weighted vote.

The committee then approved, by a 3.39-1.61 vote, the charter with the two new problem statements — regarding treatment of demand response as an operational resource and the unit-specific review process under the Minimum Offer Price Rule (MOPR) — but without the long-term capacity issue.

Schofield’s motion to strip the issue was seconded by Jason Barker, of Exelon, while representatives of Pepco and the Maryland Public Service Commission spoke in opposition.

“We think some sort of long-term capacity support is needed,” said Walter Hall, energy market advisor for the Maryland PSC. “We would read [removal] as PJM throwing up their hands.”

Gloria Godson, VP, Federal Regulatory Policy for Pepco Holdings Inc., urged members not to give up on the “thorny issue,” noting that officials in Maryland and New Jersey have attempted to create their own solutions because of PJM’s inability to solve the issue.

“I think the PJM marketplace can resolve that concern. PJM has a lot of smart people,” she said. “We can get a resolution to that issue.”

The task force was created in early 2012 to develop a long-term capacity auction. The issue charge approved by MRC set an August 1, 2012 deadline for filing a proposal with the Federal Energy Regulatory Commission for a long-term auction to provide adequate long-term revenue assurances to support entry of new capacity resources.

In April, the Federal Energy Regulatory Commission approved a tariff change resulting from the CSTF that provides new capacity resources with a mechanism to avoid clearing the capacity auction for one year if they require multi-year price assurance to be a viable project. (See Capacity Market: Three-year Price Guarantee for New Capacity.)

The task force said it would consider whether additional changes are needed after reviewing results of the May auction. While other proposals on the contentious issue have been discussed, none found enough support to win consensus.

In June and August, 2012, the MRC added two items — issues related to demand response providers capacity offers and aligning the capacity market auctions with the regional transmission expansion plan (RTEP) — to the task force’s assignments. In May, the group was tasked with considering revisions to standardize the unit specific review process in the Minimum Offer Price Rule (PJM Demand Response Providers Decry Scrutiny, “Freight Train” of Changes).

It was the latter two issues that led to last week’s charter revision. MRC’s decision to eliminate the task force’s original charge sparked a parliamentary debate with some members saying the committee would also have to vote to eliminate the problem statement. Dave Pratzon, of GT Power Group asked, “Is this a second bite at the problem statement apple?”

MRC secretary Dave Anders said that a vote on the problem statement was not needed.

PJM Seeks to Curb Capacity Auction Speculation

Members voted Thursday to approve a problem statement to consider modifying the design of the Reliability Pricing Model to ensure physical delivery of resources that clear the capacity auction.

Jason Barker, of Exelon, proposed the inquiry, saying it was needed to prevent potential reliability issues because PJM is becoming increasingly reliant on proposed new generation to maintain its reserve margin. Some planned generators that cleared for delivery two years from now “haven’t broken ground yet,” he said.

“While there doesn’t appear to be any reliability threat imminently, we believe this issue is pressing,” he said.

Some players may be speculating without any intention of bringing physical capacity by bidding into the base auction and then buying replacement capacity at a discount in the interim auctions.  Barker said one goal of the inquiry would be to “parse speculation from legitimate covering” of shortfalls and increasing penalties for those who offer capacity resources but fail to produce them in the delivery year.

The problem statement was approved by a 4.15 to 0.85 vote but not before several members expressed concerns over the inquiry.

“We could potentially create more problems than we’re solving,” said Frank Francis, director of regulatory affairs for Brookfield Energy Marketing LP,

Gloria Godson, vice president federal regulatory policy for Pepco Holdings Inc., said her company has legitimate reasons for buying in the incremental auction. “How can you define intent?” she asked.

Dan Griffiths, of demand response aggregator Comverge, said his company doesn’t speculate but needs to use the incremental auction to respond to changes in market rules. “Every year the rules change. That forces us to reevaluate our needs.” “We don’t have regulatory certainty.”

Susan Bruce, an attorney representing the PJM Industrial Customer Coalition, said the initiative should not quash competition: “I want to make sure we are keeping the welcome mat out for new resources and that we don’t discriminate.”

Barker insisted, “It is not our intent to create barriers to competitive entry.”  Any increase in deficiency penalties would apply to all resources, he said.

PJM Executive Vice President for Markets Andy Ott said the issue would be assigned to either the Capacity Senior Task Force or the Market Implementation Committee.
