Import Limit Manual Changes Clear Planning Committee

The Planning Committee last week endorsed manual changes implementing PJM’s new capacity import limits.

Reason for Change: Stakeholders approved the limits in November out of concerns that PJM might lack sufficient transmission to accommodate its growing volume of capacity imports. Cleared imports grew from about 3,000 MW to more than 4,500 MW in 2009-2012 before more than doubling to nearly 7,500 MW this year. The limits are detailed in Manual 14B: PJM Region Transmission Planning Process.

Impact: The revised methodology will limit external generation resources in next year’s base capacity auction to 6,200 MW ­– a 17% drop from the volume of imports that cleared in the May 2013 auction, while also setting five import zones with their own limits. (See Members OK Capacity Import Limit; Prices May Rise.)

New Pricing Interface in PA Feb. 1

PJM will begin pricing at a new interface near the Seneca pumped storage station in Warren County, Pa., beginning Feb. 1.

RTO officials said they expect to use the pricing point when the 451 MW Seneca plant operates in pumping mode. It will only be used to set locational marginal prices when off-cost generation is necessary to provide voltage support for the Seneca plant to pump. It is not an IROL (Interconnection Reliability Operating Limits) transfer interface.

The new interface is comprised mainly of the 230 kV buses and connected generation buses at Seneca, Glade, Forest, Elko and Shawville in the PN transmission zone. (See full interface definition.) Seneca was among 11 hydroelectric power stations LS Power agreed last year to purchase from FirstEnergy Corp.

Federal Briefs

The Federal Energy Regulatory Commission and Commodity Futures Trading Commission, after long and difficult negotiations, signed two memorandums of understanding concerning information-sharing procedures and jurisdiction over regulation of energy trading. But, disappointing some attorneys, the MOUs do not address questions of enforcement jurisdiction, which means answers will have to come from the courts.

Gas Share to Drop in 2014

Natural gas-fired generation will account for 26.8% of generation in 2014, down from 27.5% in 2013 because of rising gas prices, according to the Energy Information Administration. Coal’s share will rise this year, from 39.1% to 40.2%. In 2015, though, coal’s share should drop to 38.6% as federal mercury and air toxics regulations take effect.

In its Short-Term Energy Outlook, EIA estimated total generation averaged 11.1 TWh/day in 2013 and projected it would rise 0.3% this year and 1% in 2015. Per-customer consumption will continue to decline with energy efficiency, but industrial users will increase consumption in 2015, EIA predicts.

Panel to Act Against GHG Rule

Now that the Environmental Protection Agency has published its regulations for greenhouse gas emissions from new power plants, the House Energy and Power Subcommittee has set Jan. 14 to vote on a bill that effectively would block it. The measure introduced by subcommittee Chairman Ed Whitfield (R-Ky.) requires that a standard for coal units must have been achieved for a continuous 12 months, commercially, by a least six units at different plants. This aims at EPA’s requirement for carbon capture and storage.

The measure also requires a separate subcategory for lignite units. Sen. Joe Manchin (D-W.Va.) introduced a companion bill in the Senate.

Consensus Still Elusive on Auction Arbitrage Fix

Time is growing short for stakeholders hoping to reach consensus on rules banning capacity market speculation before May’s auction.

After two meetings last week, the Capacity Senior Task Force was still debating nine “replacement capacity” proposals — almost as many as the 11 packages the panel was considering when it failed to reach consensus in November.

Since Nov. 21, when the Markets and Reliability Committee returned the issue to the CSTF, the task force has held four meetings, including two last week. (See Arbitrage Fix Returned to Committee.)

PJM officials want to submit a plan to the Federal Energy Regulatory Commission by mid-March in order win approval in time for the Base Residual Auction. The schedule laid out by CSTF Chair Scott Baker calls for a CSTF vote after its meeting Friday, with a first read before Markets and Reliability Committee Jan. 30.

The odds of reaching an agreement may become clearer as a result of a poll CSTF Chair Scott Baker submitted to task force members yesterday.

The poll, which closes at 5 p.m. Wednesday, is an effort to thin the candidates by identifying consensus on core concepts. One question, for example, seeks to measure support for proposals eliminating the ability to profit in cleared buy bids in incremental auctions. The question then seeks to parse support for addressing the issue in time for this year’s auction or whether the task force should take more time to vet solutions.

Versions of this “IA Settlement Agreement” are featured in packages proposed by PJM, J.P. Morgan Ventures Energy Corp., Citigroup Energy and Duke Energy. Taking different approaches are proposals by Market Monitor Joseph Bowring, Old Dominion Electric Cooperative, Calpine, Exelon and Gabel and Associates. Bowring would eliminate replacement of capacity in incremental auctions except for capacity lost to force majeure events.

The poll also will gauge support for using development milestones to reduce credit obligations or capacity deficiency penalties. Another set of questions focuses on proposed requirements that bidders certify their intent to provide physical resources and not plan to buy out of their obligations in the incremental auctions, when prices are much lower than in the BRA.

An earlier poll found 90% support for raising the Capacity Resource Deficiency Charge (currently the greater of 1.2 times the Resource Clearing Price or the Resource Clearing Price + $20). A proposal to make the penalty the greater of 1.5 times the Resource Clearing Price or the Resource Clearing Price + $50 also had strong support at 86%

The same percentage of respondents endorsed changing the PJM sell offer price (currently an upward sloping offer curve with a starting price equal to the intersection of the updated VRR curve and current commitment level).  A proposal to switch to an upward sloping offer curve with the starting price floored at the BRA clearing price won almost 73% support, although that could drop in a binding, sector-weighted vote.

Cutting the number of incremental auctions from three to two won 83% support while only 67% backed a cut from three to one.

University of Delaware wind power researcher Cristina Archer sees the Great Plains as an ideal place for airborne wind turbines in the summertime because of the presence of something called “wind speed maxima,” strong currents of wind that resemble the jet stream but occur at much lower altitudes.

Airborne wind turbines are devices resembling blimps or gliders that can generate electricity as they are flown like kites in the lower atmosphere. Activity on the concept has accelerated in the past five years with at least 20 startup companies working on various concepts, including Makani Power, which was acquired by Google in May.

UTC Inquiry Moves Ahead

Members agreed last week to move forward with an initiative that could result in reduced restrictions on up-to congestion transactions.

About 70 percent of stakeholders at the Market Implementation Committee voted in favor of an issue charge to consider lifting the UTC bid cap and restrictions on the nodes that are eligible for such trades.

The measure passed over opposition from the Market Monitor and several stakeholders, who said the product is already exacerbating the underfunding of Financial Transmission Rights.

A UTC combines a day-ahead offer to sell energy at a source with a bid to buy the same quantity at a sink. The transaction is only executed if the difference between the Locational Marginal Prices at the source and sink are under a threshold set by the bidder. Current market rules limit such bids to differentials of $50 or less.

Noha Sidhom, of Inertia Power LP, proposed the review in a problem statement last month, saying the bid cap forces traders to place price insensitive bids that don’t reflect market conditions. (See PJM to Consider Relaxing UTC Rules.)

The current rules also limit such transactions to nodes historically available for interchange transactions, excluding those load buses below 69 kV and buses for generators below 100 MW. “Expanding nodes would make [UTCs] a true hedge when the market is more volatile,” Sidhom said.

The issue charge directs the MIC to consider alterations to UTCs during special sessions in the first quarter of 2014, with a FERC filing for approval of Tariff changes anticipated in July.

Impact of FirstEnergy Hunterstown Project (Source: PJM Interconnection, LLC)
(Source: PJM Interconnection, LLC)

As expected, PJM transmission planners said last week they will recommend the PJM Board of Managers approve FirstEnergy’s proposed $8 million congestion-relief upgrade in the MetEd zone.

“We’re already looking at the FirstEnergy project as the project we would like to move forward on,” PJM’s Tim Horger told the Transmission Expansion Advisory Committee Thursday.

The FirstEnergy project bested two proposals by LS Power to relieve congestion on the Hunterstown 230/115 kV transformer. The LS Power projects, estimated at more than $60 million each, had benefit to cost ratios of less than 2, far below FirstEnergy’s B/C ratio of more than 6.

Reliability tests of the LS Power proposals indicated one would require a new circuit breaker and the other caused reliability violations, additional costs that would further reduce their benefit-cost ratios. Adding either LS Power proposal to the FirstEnergy project would have an incremental B/C ratio of less than 1, Horger said.

The FirstEnergy project, expected to be completed in 2017, includes the installation of a second Hunterstown 230/115 kV transformer and reconductoring of the Hunterstown-Oxford 115 kV line

The project has a total revenue requirement of $11.7 million and is expected to produce savings with a net present value of $71.6 million over 15 years, a payback of 6.1 to 1. The calculations are based on a carrying charge rate of 16.7% and a 7.7% discount rate.

The three projects were among 17 congestion relief transmission proposals submitted by developers in September. PJM rejected the other 14, saying they failed to provide sufficient benefits or targeted problems that were already addressed by other upgrades. (See PJM to OK Only 1 of 17 Congestion Relief Proposals.)

$238M in Additional Reliability Projects

The FirstEnergy project will be recommended to the Board of Managers in February along with seven reliability projects totaling more than $238 million, including four in Penelec (total $82 million) and one each in PPL ($350,000), AE ($300,000). The biggest project of the seven is a $155 million upgrade in Dominion to correct overloads on the Franconia 230kV to Van Dorn 230kV line and four other lines.

PJM Shivers to New Winter Demand Record

Sub-zero temperatures from Toledo to Tennessee pushed PJM to its limits last week as the RTO overcame the loss of nearly 40,000 MW of generation during an arctic blast that set a new winter demand record.

Outages by Fuel Type (Source: PJM Interconnection, LLC)
(Source: PJM Interconnection, LLC)

Demand response, voluntary conservation and imports helped PJM avoid shedding load as demand hit 141,500 MW Tuesday evening, besting the previous winter peak — set Feb. 5, 2007 — by nearly 5,000 MW.

The RTO survived Tuesday’s peak despite about 38,000 MW in generation outages, almost 20% of its installed capacity. “We really exhausted every megawatt we had on the system,” Adam Keech, director of wholesale market operations, told the Market Implementation Committee in a briefing Wednesday.

Some plants failed to start, suffered tube leaks or were unable to convert to backup fuel. “We’ve seen everything,” Executive Vice President for Operations Mike Kormos said during a press conference Tuesday morning.

What sent temperatures plunging and power and natural gas prices skyward was an unusual visit by the polar vortex, a low pressure system that normally circles around the North Pole.

Temperatures of -10 or below were recorded Tuesday in Ohio, Michigan and Pennsylvania. The negative numbers reached as far south as Kingsport, TN, which reported -1 and Blacksburg, VA, which registered -5.

PJM power prices were above $200/MWh for most of the period from Monday evening through Tuesday evening, peaking at more than $1,800/MWh during Tuesday’s morning and evening peaks.

Natural gas for Tuesday delivery hit a record $95/mmBtu at Transco’s Zone 6 non-New York hub in PJM, Natural Gas Intelligence reported. U.S. gas demand hit a record 130 billion cubic feet per day Monday, topped by a new record of 134 Bcf/d Tuesday, according to Bentek Energy.

Generators told PJM, “`I can get gas but it’s very expensive. Do you still want it?’” Executive Director of System Operations Mike Bryson told Platts Energy Week later. “And we were in a position where we needed every megawatt we could get on the system.”

One bright spot: The gusts that accompanied the cold boosted PJM wind production to more than 3,000 MW, according to the American Wind Energy Association.

Below is a chronology of PJM’s response to the arctic blast, based on PJM records and briefings from PJM officials and industry news reports.

Monday, Jan. 6

PJM braced for the arrival of the vortex Monday as subzero temperatures began moving east from the western portion of the RTO. Shortly before noon, PJM issued a Maximum Emergency Generation Alert for Tuesday for the entire PJM RTO — a signal that the RTO may need every available megawatt of generating capacity. They also issued a press release calling on consumers to conserve power the following day.

Arctic Blast Boosts LMP's Above $1000/MWh (Source: PJM Interconnection, LLC)
Arctic Blast Boosts LMP’s Above $1000/MWh (Source: PJM Interconnection, LLC)

PJM and state regulators urged consumers to reduce energy use during the emergency. “Every little bit helps,” Kormos said. “There’s 60 million people in our footprint. If everyone does their part, that could easily add up to one nuclear plant, which is 1,000 MWs.”

“We’re very close [to generation limits],” Kormos added. “The last couple hundred megawatts could allow us to not have to take any forced interruptions.”

PJM received a waiver from the Federal Energy Regulatory Commission under Order 787, allowing RTO officials to share information with natural gas pipelines serving the region. PJM held conference calls with pipelines Friday and Monday and individually validated gas nominations for the RTO’s gas generators. Keech said there were no natural gas curtailments.

“The pipelines came through pretty well,” Gary Helm, lead market strategist, told the Market Implementation Committee in a briefing. “We only saw two compressor outages.”

At about 5 p.m., the RTO lost about 1,500 MW of generation, including the FirstEnergy’s 911 MW Beaver Valley nuclear unit 1, which tripped after a transformer malfunction.  Operators requested synchronized reserves and shared reserves from NYISO. Load mounted faster and higher than expected, topping off 5,000 MW above forecast at 131,900 MW.

Keech said operators’ ability to forecast load was hamstrung by a lack of comparable temperature data. “We couldn’t find a temperature set [with extreme cold throughout the RTO] for the last decade. And if you go back that far the [RTO] footprint was so different it’s probably not even useful.” Keech said.

The synch reserve event was ended after a little more than an hour at 6:09 p.m. Shortly before 7:30 p.m., another large generator tripped.

At 7:50, with reserves growing short, operators reduced voltage across the RTO by 5% to help them through the evening peak. The action, which lasted about an hour, triggered scarcity pricing ­— sending prices briefly above $1,000/MWh.

Tuesday, Jan. 7

Overnight, operators became alarmed after the “valley load” — the lowest load of the day —came in 4,000 MW higher than the projected 116,000 MW. About 2 a.m., expecting a morning peak of 140,000 MW, operators issued a request for emergency energy for 6 through 11 a.m.

Shortly before 3 a.m., they issued a warning that they might again reduce voltage.

At 4:30, they issued a call for 1,900 MW of emergency demand response and issued a Maximum Emergency Generation Action, notifying market participants that off system energy sales from PJM capacity resources may be recalled. Demand response provider EnerNOC Inc. said it was the largest winter dispatch in PJM history.

About 1,100 MW of emergency energy began flowing from MISO and NYISO at 6 a.m., but at 6:30 operators called on 100% synchronized reserves to respond to a low Area Control Error. A second spin event was initiated shortly after 8 a.m., when an unnamed unit tripped.

The morning peaked at 138,600, a new — if short-lived — winter record. Prices were in the $1,800/MWh range from 7 to 11 a.m.

At 3 p.m., operators again called on DR for an evening peak projected at 142,000 MW. However, an unexpected influx of imports — as much as 10,000 MW — allowed them to cancel the DR call shortly after 6 p.m.

The evening peaked at 141,500 — below projections but a new winter record nonetheless.

Bryson credited voluntary conservation. “There were times when we thought we were going to be short on reserves and the load just didn’t come in,” he said. “And it’s probably representative of a very good consumer response.”

Wednesday, Jan. 8

Expecting a morning peak of 136,600 MW, PJM again issued a Maximum Emergency Generation Action, called on DR and issued a request for emergency energy.

Generator outages would peak Wednesday morning at 39,520 MW. But with temperatures rebounding, the morning peak would hit only 134,500. With load coming in lower than expected, the RTO cancelled the DR call at 6:30 and the Maximum Generation Action at 9 a.m.

The crisis was over.

PJM: Overbilled $25M in Reactive Charges

PJM overcharged members by more than $25 million in reactive service charges last year and will begin providing refunds this month.

Reactive Credits (Source: PJM Interconnection, LLC)
Reactive Credits (Source: PJM Interconnection, LLC)

Adam Keech, director of wholesale market operations, told the Market Implementation Committee last week that reactive credits in the real time market were inflated by $25 to $30 million between August and December as a result of a software error.

In December 2012, PJM changed the way it allocated local reactive power costs: Costs that were previously allocated to all Day Ahead load, DECs and exports were allocated to the individual transmission zone.

A subsequent change to the logging process, effective Aug. 1, also inadvertently changed the settlement process. As a result, resources committed in the DA market for reactive support were credited with make whole payments in real time.

“Anytime a unit wasn’t following dispatch we assumed it was redispatched for reactive” service, Keech explained.

Officials discovered the error after noticing RT reactive credits, which had been negligible compared with DA credits, grow to more than $5 million per month. The error was corrected for settlements beginning Dec. 20.
