Monitor: Rule Changes Could Almost Triple Capacity Revenues

Adopting the Market Monitor’s proposed changes to capacity market rules could almost triple auction revenues, the Monitor said in a report last week.

The Monitor said the $5.5 billion generated during the 2016/17 Base Residual Auction last year would have been $6.9 billion if the Short-Term Resource Procurement Target had been eliminated. The target cuts the amount of capacity acquired in the base auction by 2.5%, setting it aside for purchase in incremental auctions for the delivery year.

The 2.5% reduction removed 4,153 MW from the RTO demand curve, the Monitor said in an analysis of last year’s BRA. The target, which reduced clearing prices and quantities for all regions in the auction, should be eliminated, the Monitor said.

“The 2.5% demand reduction is a barrier to entry in the capacity market for both new generation capacity and new DR capacity,” the Monitor said. “The logic of reducing demand in a market design that looks three years forward, to permit other resources to clear in incremental auctions, is not supportable and has no basis in economics.”

‘Inferior’ Demand Response

The Monitor said revenues would have been $10.1 billion if only generation and Annual DR were offered, and Limited and Extended DR were eliminated.

The Monitor said Limited and the Extended Summer DR should be eliminated, and the restrictions on the availability of Annual DR ended, so that DR has the same obligation as generation to provide capacity year round.

“The Annual DR product definition is the only one consistent with being a capacity resource,” the Monitor said.

Eliminating both the 2.5% holdback and “inferior” DR would have produced $15.8 billion in revenues, the Monitor said, almost three times what capacity resources actually received.

Import Impact

The report also looked at the impact of generation imports on clearing prices.

It found that excluding external generation without firm transmission would have boosted revenues to $6.8 billion, an increase of almost $1.3 billion.

Reducing external generation offers by 25% would have increased revenues by $637.5 million, the report said.

The Federal Energy Regulatory Commission last week approved a rule change that will reduce capacity imports by as much as 17% from what cleared in the 2013 auction. (See related story, FERC Clears Capacity Import Limits.)

Bankers: Change Timing on Capacity Revenue Reassignments

PJM rules are making it difficult for banks to purchase capacity providers’ revenue streams, Citigroup Energy told the Markets and Reliability Committee last week.

Citigroup Energy’s Barry Trayers presented a first read of a proposed problem statement to consider changing the rules, which require PJM to wait until after the third incremental auction (IA) before reassigning revenue streams from one PJM member to another.

Trayers said Citigroup purchases revenue streams at a discount from capacity providers who prefer to receive their proceeds in a lump sum. “I have customers out there who want to do it. It’s just very difficult to do it,” under current rules, he said. “I’m only [seeking to change] when PJM approves the transaction.”

Trayers said the rule will need to be changed because a proposed Tariff change now pending before the Federal Energy Regulatory Commission would eliminate the third IA, potentially putting such deals in limbo. (See Second Time Not the Charm.)

Harry Singh, of Goldman Sachs, also supported consideration of the rule change but asked for further clarity on whether PJM considers these “auction specific capacity” transactions to be “physical transactions” or simply a reassignment of receivables.

Stu Bresler, vice president of market operations, said the RTO supports “opening discussion” on the issue. PJM Chief Financial Officer Suzanne Daugherty said the change proposed by Citigroup should not increase risks to PJM members because the capacity provider will remain liable for capacity deficiency charges. PJM will retain the capacity provider’s posted collateral and could tap into the reassigned cash flow if needed to cover any shortfalls, she said.

Trayers’ request to waive first read and have an immediate vote on the problem statement was rejected by MRC chair Mike Kormos when several members objected. The issue will be brought to a vote at the MRC’s next meeting.

Ott: Need to Reconsider ARR Allocations

PJM will ask stakeholders to consider changing the historical allocation of Auction Revenue Rights, Executive Vice President for Markets Andy Ott told members last week.

Ott told the Members Committee webinar that the number of facilities resulting in ARR infeasibilities have increased steadily since 2012, largely due to transmission outages (see chart).

ARR Infeasibilities (Source: PJM Interconnection, LLC) — (Source: PJM Interconnection, LLC)

“We’ve seen constraints come up that we haven’t seen before,” Ott said. “… PJM can build its way out of it, but it’s going to take years.”

Ott said PJM will begin discussing Stage 1A ARR allocations at the end of May or early June in hopes of making changes before the next allocation in spring 2015.

ARRs are allocated annually to firm transmission service customers, entitling them to receive a share of the revenues from the annual auction of Financial Transmission Rights. The infeasibilities, in turn, contribute to shortfalls in FTR revenues.

Total ARRs are capped based on historical generation capability and zonal base load. For the 2014/15 allocation, the zonal base load was based on the minimum daily peaks for the year beginning Oct. 22, 2012.

Infeasibilities have increased due in part to uncompensated power flow (loop flow) and additional market-to-market flowgates, but increased transmission outages is the primary factor, Ott said.

Generation retirements — which were not anticipated when the Stage 1A process was designed — also have played a role. More than 15% of Stage 1 historical generation (25,544 MW) has retired or submitted deactivation notices.

The retirements require PJM to remap historical resources to an equivalent generator or create a “dummy” generator for ARR and pricing purposes. This can create additional Stage 1A infeasibilities, PJM says.

“The system seems to be able carry less and less of” the historic, “grandfathered” rights, Ott said. “We really need to take a fresh look at this. The solution is a high-level solution: Change the way things are allocated.”

In June, the Federal Energy Regulatory Commission rejected a complaint (EL13-47) by FirstEnergy Solutions Corp. that sought to bill all transmission users to make up FTR shortfalls. Since then, market participants say, the problem has only gotten worse with cumulative shortfalls exceeding $1.1 billion. (See FTR Holders Seek Shortfall Fix.)

Members to Consider Easier Sharing of Real-Time Generator Data

Members agreed to consider an easier method for transmission owners to access real-time generator data, an effort to improve situational awareness and emergency response.

The Markets and Reliability Committee last week approved a problem statement by AEP’s Dana Horton to ease TO access to real-time MW output and MVar data. The data would be used as inputs to the TOs’ state estimators.

Horton said TOs are discouraged from obtaining the information under the current process, which he said is “burdensome and time-consuming.”

The information will improve TOs’ ability to “assess the impacts of external conditions and be able to develop effective plans or implement corrective actions to maintain reliability,” the problem statement said.

Under an issue charge approved by the MRC, the Operating Committee will consider developing new access rules and determine “the appropriate uses, storage and protection of the data.”

The work is expected to take three months.

Quick Transmission Fixes Approved by FERC

The Federal Energy Regulatory Commission approved PJM’s plan for selecting transmission projects that can easily and cheaply resolve constraints in Locational Delivery Areas (LDAs).

The new rules require PJM staff to identify — before posting the planning parameters for each Base Residual Auction — Locational Deliverability Areas in which the Capacity Emergency Transfer Limit is less than 1.15 times the Capacity Emergency Transfer Objective (See Quick Fix Transmission Upgrades Ok’d).

Upgrades that increase the ratio to more than 1.15 would be added to the Regional Transmission Expansion Plan (RTEP) if they cost less than $5 million and can be completed prior to June 1 of the Delivery Year. Projects that duplicate upgrades whose cost is already assigned to an interconnection customer would be excluded.

Such projects are unlikely to be common. PJM told the commission that it had identified no circumstances that would justify such projects in the last three years.

FERC approved the proposal over the objections of Utility Risk Management Corp. (URMC) and NextEra (ER14-456).

URMC said the proposal would hurt merchant transmission developers by allowing PJM to supplant merchant upgrades. NextEra argued that the proposal would disguise price signals and reduce transparency and innovation.

FERC said the narrow scope of these quick-fix projects was enough to alleviate these concerns and ensure consistency with Order 1000.

FERC endorsed PJM’s contention that, in relieving minor constraints that are unlikely to return in future years, it prevent misleading price signals.

As a condition of the approval, FERC required that PJM post an annual list of quick-fix proposals and recommended that the RTO and its stakeholders devise operational procedures in case such a project cannot be completed by June 1 of the relevant delivery year.

NERC Draft Rules for Physical Security

Below is a summary of the six requirements included in the draft reliability standard for physical security of the grid.

Transmission owners should perform a risk assessment of transmission stations and substations to determine which ones, if disabled or damaged, could result in “widespread instability, uncontrolled separation, or cascading within an Interconnection.” Assessments should be repeated every 30 months if such a vulnerability is identified and every 60 months if not.
Transmission owners should have an unaffiliated third party verify the risk assessment. Such third parties can be a registered planning coordinator, transmission planner or reliability coordinator, or “an entity that has transmission planning or analysis experience.”
Transmission owners with stations or substations identified under Requirements 1 or 2 that are not under their direct control must notify the operator of a primary control center that does control the stations of their critical status.
Operators of stations, substations or primary control centers identified as critical under Requirements 1 through 3 must conduct an evaluation of potential threats and vulnerabilities of those facilities. The evaluation must consider the characteristics of the facilities and any prior history or attack of similar facilities, and incorporate any threat intelligence provided by NERC, law enforcement or other authorities.
Operators of facilities identified during the threat analyses must develop within 120 days a physical security plan for the facilities, incorporating security measures, law enforcement contact information, a timeline for implementing the security plan and ways to conduct ongoing threat evaluations.
Transmission owners and operators must have a third party evaluate the threat analysis in Requirement 4 and the security plan developed in Requirement 5. The evaluation must be completed within 90 days of the security plan completion, and any changes suggested by the third party must be performed within 60 days.

Generic Transition Mechanism for Capacity Changes Dropped

PJM last week withdrew a proposal to develop a generic transition mechanism to hold capacity providers harmless for future rule changes.

The RTO’s proposed problem statement and issue charge was withdrawn from the agenda of the Markets and Reliability Committee without explanation. There was no indication why the issue was withdrawn or whether it will be added to a future agenda.

Members had greeted the proposal coolly when PJM announced it at the MRC meeting in March. (See PJM Proposes Generic Transition Rule for Capacity Market Changes.)

The proposal was prompted by the transition mechanism approved by members to protect generators whose installed capacity ratings are reduced by seasonal verification tests.

MRC/MC Briefs

The Markets and Reliability Committee approved the following Tariff and Operating Agreement revisions last week:

Clarifications to the Tariff and OA giving generators providing Tier 2 synchronized resources the ability to aggregate these resources in order to avoid retroactive penalties for failure to respond appropriately when called. New language will also be added to Manual 11: Energy & Ancillary Services and Manual 28: Operating Agreement Accounting. Aggregation will not be used in calculating Tier 2 Synchronized Reserve credits; each resource will continue to be credited independently.
Revisions to the Tariff to reflect current PJM practices regarding credit available for virtual transactions. PJM instituted the policy as the result of a FERC Order in 2004 but failed to make accompanying changes to the Tariff. These revisions also correct for changes in credit policy since 2004 (e.g., working credit limit discount is now 25%, not 15%).
Clarifications to the Tariff and OA on regulation shoulder hour lost opportunity costs (LOCs). As a result of a review, PJM discovered that the documents didn’t adequately describe the calculation of the deviation between the regulation set point and the expected output of each regulation resource.
Changes to the Tariff and OA reflecting PJM’s change in mailing address to: PJM Interconnection, L.L.C. 2750 Monroe Blvd., Audubon, PA 19403.

The MRC also approved the following manual changes:

Manual 13: Emergency Operations — The changes will allow declaration of Cold Weather and Hot Weather alerts several days in advance instead of the day before.
Manual 18: PJM Capacity Market — Conforming the manual to recent FERC orders, including seasonal verification testing and Capacity Import Limits effective with the 2017/2018 delivery year. (See related story, FERC Clears Capacity Import Limits.)

The Members Committee endorsed the following consent agenda items last week:

Revisions to PJM’s Tariff and Operating Agreement to clarify agreements and transactions to which PJM Settlement, Inc. is not a party.
Operating Agreement and Tariff revisions to effectuate the eSuite application name changes (i.e., changing eSchedules and EES to InSchedule and ExSchedule, respectively). Proposed improvements to eSuite applications are slated to continue through 2015.

NRC Gives Exelon’s Limerick Extension for Fukushima Fix

The Nuclear Regulatory Commission granted Exelon’s request for an additional two years to make upgrades to the reactor buildings at its Limerick Nuclear Generating Station. The NRC in 2012 ordered Exelon to take steps to prevent hydrogen buildups similar to what occurred during the Fukushima disaster in Japan in 2011.

The Limerick reactors share some design similarities with the Japanese units. The NRC ordered installation of a “hardened wetwell vent” system to extract combustible gas from building up and possibly exploding. “The installation of such vents is one of our post-Fukushima requirements,” said NRC spokesman Neil Sheehan. Exelon will have until the end of a refueling outage in spring 2018 to complete the work at Unit 1 and until the end of a refueling outage in spring 2017 to complete the work at Unit 2, the NRC said.

NRC: Higher Cooling Water Temps OK for Millstone

The higher water temperatures of Long Island Sound aren’t too high for the Millstone nuclear plant to use, according to the Nuclear Regulatory Commission. The NRC granted Dominion’s Millstone Unit 2 a license amendment to allow operation if its cooling water, drawn from the Sound, rose in temperature to 80 degrees. Unit 2 was forced offline for 12 days in 2012 when Sound water temperatures rose above the then 75-degree limit. The NRC is considering a similar amendment request for Millstone Unit 3.

“We’ve seen a long-term trend over the last 40 years of Long Island Sound temperatures steadily increasing,” Millstone Spokesman Ken Holt said. In 2012, the average temperature in the Sound near the Unit 2 intake pipe was about 77 degrees, he said. The company believes the five-degree margin will be sufficient to allow it to continue operations without costly unplanned shutdowns, he said. “We think we can stay well within the limit,” he said.

Members Split Over Change in Reserve Procedures

Stakeholders split last week over a PJM proposal to change how the RTO captures the cost of deploying additional reserves during extreme weather.

PJM’s Lisa Morelli presented a first read of the proposal — which is intended to capture operators’ reliability actions in Locational Marginal Prices rather than uplift — at last week’s Markets and Reliability Committee meeting.

Stakeholders representing generation expressed support for the proposal while those representing load said they feared it could lead to unduly conservative operations and higher overall costs.

It would increase day-ahead and real-time reserve requirements when hot- or cold-weather alerts or max emergency generation alerts are issued for the RTO or for either the Mid-Atlantic-Dominion or Mid-Atlantic regions.

“On a day like this there’s a ton of uncertainty,” said PJM Executive Vice President for Operations Mike Kormos, citing generator performance and forecasts for weather, load and interchange. “We can’t roll the dice and hope things go away.”

The adder for day-ahead reserves would be set at 3% of forecasted load, boosting reserves from 6.27% to 9.27%. The real-time reserve adder would be equal to the default Mid-Atlantic-Dominion (MAD) synchronized reserve requirement of 1,300 MW.

The increases would be implemented only if operators believe the additional resources can be scheduled without causing operational problems. The real-time adder would be reduced to 50% of the MAD synchronized reserve requirement or lower if the higher amount becomes problematic.

The increased reserves would be reflected in market clearing engines, ensuring that the costs go into LMPs and not uplift.

It is the first proposal to result from a problem statement approved by members in November. (See MIC to Consider Real-Time Pricing Changes.)

“This has been a long time coming,” said PJM Vice President for Market Operations Stu Bresler. “… This is very important to us.” Bresler said the best solution — changing reserves in real time — would be more complex and less transparent.

Ed Tatum, of Old Dominion Electric Cooperative, called the proposal “reactionary.”

“Sixteen years and 24 days into this LMP business … we keep on doing non-market things,” he said. “… We are moving further and further away from the concept of a market. We’re taking it more into an administrative construct.”

David “Scarp” Scarpignato, of Direct Energy, said the proposal could lead to overly conservative operations and increase costs to load. PJM already carries reserves equal to 150% of the largest single contingency, while other regions use only 100%, he said.

“We have very big problems with this,” he said. “PJM already has more conservative synchronized and primary reserve targets than other areas.”

Jason Barker, of Exelon, said Scarp had mischaracterized the PJM proposal. Last July, Barker said, PJM dispatched demand response at $1,800/MWh and Exelon’s peaking generators at “hundreds of dollars” at a time when LMPs were only about $60/MWh. “All of these [costs] were paid through uplift,” he said.

PJM, which wants to implement the changes in time for this summer, will bring the proposal to votes at the MRC and Market Implementation Committee next month. It was developed during meetings of an MIC subgroup on Energy/Reserve Pricing & Interchange Volatility.

At a meeting of the subgroup yesterday, PJM officials said that logistical problems prevented them from producing simulations to gauge the impact of the changes.
