AP South, Cleveland Draw Congestion Relief Proposals

2013 Market Efficiency Proposals (Source: PJM Interconnection, LLC)AP South and the Cleveland interface attracted the most attention in PJM’s inaugural window for proposed market efficiency upgrades.

PJM staff provided the Transmission Expansion Advisory Committee last week with a summary of 17 proposals ranging from $200,000 to $64 million.

Merchant developer LS Power was the most ambitious, proposing four projects totaling $181 million in eight zones. Transource (American Electric Power and Great Plains Energy) was second, proposing three projects in the AEP and ATSI zones totaling $135.5 million.

The three incumbent utilities that took part — Commonwealth Edison, Dominion Virginia Power and FirstEnergy — all stayed at home, with proposals in their own transmission zones. Duke (with partner American Transmission Co.) did the same, proposing one project in the Duke Ohio-Kentucky zone.

AP South

AP South attracted seven congestion relief proposals.

Transource proposed two alternatives to address congestion at AP South and the AEP-Dominion interface. The cheaper option features a 500 kV substation with series capacitors at a cost of $39.3 million. A second builds on the first with additional series compensation at an extra $24 million.

Dominion proposed three projects incorporating Thyrister-controlled series capacitors at costs ranging from $20.1 million to $24.6 million (total cost $69.4 million).

FirstEnergy and LS Power made pitches for AP South and the Hunterstown 230/115 kV line with projects of $54.3 million and $61.7 million, respectively.

Separately, LS Power proposed a new Hunterstown-Cumberland 230 kV line and substation improvements for $63.9 million. FirstEnergy proposed spending $8 million to add a 230/115 kV transformer and reconductor the Hunterstown-Oxford 115 kV line.

FirstEnergy, LS Power and Transource each proposed projects to relieve congestion at the Cleveland Interface.

The most expensive is FirstEnergy’s $61.7 million proposal to improve a 138 kV substation in the ATSI zone.

LS Power’s $44.9 million project, which includes the ATSI and PENELEC zones, would add a new Erie West–Ashtabula 345 kV line and a 345/138 kV transformer.

Transource offered the least costly project, a new 138 kV substation in the ATSI zone at a cost of $32.9 million.

Next Steps

PJM’s request for congestion relief proposals was its first under Order 1000, in which the Federal Energy Regulatory Commission sought to increase competition by largely eliminating utilities’ monopoly over transmission development in their territories.

Proposals must clear a minimum 1.25 benefit-to-cost threshold to be considered by the Board of Managers for inclusion in the Regional Transmission Expansion Plan. PJM staff will review the projects through January and make recommendations to the Board in February.

PJM will conduct independent cost reviews on projects exceeding $50 million and on those below $50 million that have tight benefit-cost margins, said PJM’s Paul McGlynn.

Summer 2013 Load Growth Fastest Since Recession

PJM’s weather normalized summer peak increased 950 MW in 2013, the largest increase since load growth resumed after the recession.

The 0.6% increase over 2012 is “no great shakes but moving in the right direction,” PJM’s John Reynolds told the Planning Committee during a briefing last week.

The peak was 0.2% (368 MW) below PJM’s forecast. “It’s been a challenging time for us for load forecasting since the recession,” said Steve Herling, vice president of planning. “The primary input is econometrics — over which we have no control.”

Peak diversity for 2013 as 0.3%, much lower than the forecasted 4.3%, as a result of the single RTO-wide heat wave July 15-19.

It was the first summer that the top five coincident peaks have come in the same calendar week since PJM started collecting the data. “The entire story of the summer of 2013 can be told in one week in the middle of July,” Reynolds said.

PC OKs Move to Flag Transmission Upgrades Earlier

The Planning Committee approved a manual change that will result in PJM identifying potential transmission upgrade requirements earlier in the study process.

In past years, studies identified many reinforcements which were ultimately not needed as projects dropped out of the backlogged transmission interconnection queue. As the backlog has been reduced, however, some projects have cleared the Impact Study phase without any apparent violations, only to have violations indicated when they are evaluated at 100% in the Facilities Study.

As a result, PJM plans to eliminate the 19% probability for Feasibility Studies and replace it with the 53% currently used for Impact Studies. Impact Studies will use the 100% probability. The changes will be incorporated in Manual 14B. (See Transmission Studies to Flag Upgrades Earlier.)

PJM Kicks Off Grid 20/20 Conference

PJM CEO Terry Boston and Federal Energy Regulatory Commissioner Cheryl LaFleur kicked off PJM’s third annual Grid 20/20 conference in Philadelphia last night.

In keeping with the theme of this year’s conference, LaFleur told an audience of about 100 about the need to create a “culture of resiliency.”

“When there is a problem on the grid, very rarely is it the result of one thing. It’s a succession of mistakes where if you had defense in depth it could have been stopped,” she said. “There has to be a line of sight between what people are doing and the bigger issues…These little thing will add up to the big things.”

About 180 people gathered for today’s daylong session at the Sheraton Society Hill.

Exelon Reaps up to $100 Million in PTCs

Exelon continues to take advantage of the production tax credit for wind power even as it protests the PTC as a market distorter, particularly damaging to its giant nuclear fleet’s revenue. A Bloomberg New Energy Finance analyst pegged Exelon’s own wind PTCs for this year at $75 million to $100 million, based on the company’s 1.3 GW of wind projects. To environmentalists’ criticism, Exelon says it has a fiduciary responsibility to its shareholders to take the tax credits, but it opposes all market-distorting subsidies. Although Exelon has suffered this year from low power prices, Morningstar analysts say the company’s prospects are good because its low-carbon nuclear fleet will be valuable for years to come.

PJM to Order Temperature Adjustments on Steam Units

PJM will require all steam generators to adjust their capacity ratings based on summer peak load conditions under manual changes outlined to the Planning and Market Implementation committees last week.

Manual 21 currently requires such temperature corrections only for combustion turbines and combined cycle units. The revisions will extend the requirement to coal and nuclear steam units.

About 60% of steam units already perform temperature corrections, with half increasing their capacity ratings and half reducing them, said PJM’s Tom Falin. The average adjustments were 0.5% with the largest adjustment 2%.

PJM also will begin requiring hydropower and pump storage units to perform their annual capacity tests — now allowed to be conducted any time — during the summer.

The adjustments can affect generators’ installed capacity values as well as capacity interconnection rights.

PJM plans to implement the changes after seeking endorsement by the Markets and Reliability Committee in the first quarter of 2014.

The changes will be incorporated in PJM’s planning studies in summer 2014, with a likely transition period before use for markets purposes.

PJM Changing Tier 1 Synchronized Reserve Estimates

PJM is changing the way it estimates Tier 1 Synchronized Reserves and is open to lifting the cap on demand response participation in Tier 2, officials told the Operating Committee last week.

A review of more than 40 Synchronous Reserve events since January 2012 found that only 71% of estimated Tier 1 reserves responded when called upon. The response rate drops to 62% when two outlier events — in which there was over-performance — are excluded.

PJM officials decided to take a look at their estimation methods after an SR call during the Sept. 10 heat wave provided only 12% response.

PJM plans to implement several changes in its methodology by the end of the year:

  • Cap all units used in the Tier 1 estimate at the lesser of Eco Max or Spin Max (by end of year).
  • Remove all hydropower units – which don’t respond automatically to synch reserve events — from the Tier 1 estimates (already done).
  • Remove all combined cycles units from the Tier 1 estimate except units that have submitted a Spin Max < Eco Max (done).
  • Remove units with a manual dispatch instruction from the Tier 1 estimate (by end of year).
  • During hot or cold weather alerts, the Degree of Generator Performance (DPG) modifier will be used to adjust the Tier 1 response estimate (by end of year).

Tier 2 Synchronous Reserve Response Performance for Events > 10 Minutes (% of Assignment Provided) (Source: PJM Interconnection, LLC)

Units assigned regulation, which are assumed to be able to respond with the MWs outside their regulation band, will remain in the Tier 1 estimate.

Units providing constraint control are expected to respond to a Synch reserve event and will remain in the estimate.

Tier 2 Unchanged

Also unchanged are the Tier 2 calculations. PJM filed new Tier 2 penalty rules for nonperformance Nov. 1 (ER14-297).

The new rules were approved by the Members Committee Oct. 24 in response to concerns that the existing penalties were insufficient to ensure compliance.

Demand response and generation have each provided 59% of requested MWs for Tier 2 events of 10 minutes or longer in 2013, according to a PJM analysis provided last week to the Operating Committee. That was a decline after steady increases in performance from 2009 through 2012.

PJM officials said they don’t know the reason for the fall off in performance. “There’s nothing that jumped out” as a cause, said PJM’s Tom Hauske.

DR Cap

Although the cap on DR participation was raised to 33% last fall, it provided only 224 of the 925 MW (24%), with generation providing the remainder.

DR typically offered between 200 and 250 MWs per hour into the market. Mike Bryson, executive director of system operations, said the decline in SR prices affected the volume of DR bidding into the market, rendering the cap moot.

Asked by EnergyConnect’s Bruce Campbell whether PJM still sees a need for a limit on DR participation, Bryson responded: “I think it’s certainly worth discussing.”

Adam Keech, director of wholesale market operations, said that PJM would need to improve its data collection before considering a change in the cap. About 9% of MWs assigned to DR failed to provide PJM with data in 2013, down from 46% in 2012.

Officials said one concern with removing the cap would be the operational impacts because of differences in the ramp rate of DR versus generation in the first 10 minutes of spin events.
