MISO: Reserves Eroding Before Winter

By Chris O’Malley and Rich Heidorn Jr.

MISO is depending on its transmission system, better information about natural gas pipelines and voluntary demand reductions to meet peak loads over the next two winters.

MISO told the Federal Energy Regulatory Commission last month that its Central and North regions expect a 2.3-GW shortfall in 2016, with three of the six zones failing to meet target reserve margins. While the recently integrated South region shows a 2.5-GW surplus over the same period, transmission constraints will limit the ability of the short zones to import the ISO’s spare megawatts.

“Reserve margins are tightening across the footprint, the result of aging infrastructure, environmental regulation, and decisions made by legislatures, utilities and regulators to diversify the generation fleet,” Eric Callisto, president of the Organization of MISO States (OMS) and a member of the Wisconsin Public Service Commission, told FERC. “The erosion of excess reserves understandably is of great concern to us all. And consistent with our relative roles in the industry, I believe there has been an appropriate response in the MISO footprint to this challenge.”

Some are skeptical of the forecasts, the result of a MISO survey of load-serving entities.

MISO officials had been warning last November that they faced a capacity shortfall of as much as 5 to 7 GW in 2016-17 due to the loss of coal-fired generation. In January, officials cut the forecast shortfall to 2 GW. In April, MISO told FERC it had reduced the projected shortfall further to 500 MW.

FERC Commissioner Philip Moeller noted that the projection assumed an increase in residential demand would be negated by a decline in industrial load. “If [industrial demand] turns around, as we hope it does, then your assumptions start getting shaken real quickly,” Moeller said.

Last Winter

Last winter was the coldest in two decades for many areas of MISO, with increased outages, record congestion and higher prices and uplift. Heating degree days rose 25% from the previous winter pushing average load was up 7%.

MISO set a new winter peak of 109.3 GW on Jan. 6, a 9% jump from the previous peak. The following day, MISO narrowly avoided having to shed load as it fell 1,900 MW short of operating reserves, leaving it with only 300 MW.

MISO’s Independent Market Monitor, Potomac Economics, said ISO operators were late to recognize the shortage and approved 700 MW in exports that began flowing at 7 a.m., 10 minutes before it fell into a shortage and 15 minutes before it declared a Maximum Generation Alert.

Prices

Day-ahead energy prices averaged $51.52/MWh for the winter, almost 80% higher than the previous year.

Fuel delivery problems and low storage levels led to extreme natural gas price volatility. Generating costs for gas units in the Midwest region were as much as 10 times that in the South, reflecting a disparity in gas costs. Natural gas prices at Chicago rose to $8.02/MMBtu, more than double the price a year earlier.

In late February, prices stayed above $10/MMBtu for 12 consecutive days. At the benchmark Henry Hub in Texas prices never rose above $8.

Midwest markets will have increased access to Marcellus and Utica gas by the end of 2014 with the addition of 425 MMcfd of pipeline capacity, FERC staff said in a presentation at the commission’s Oct. 16 meeting. As of Sept. 30, the price at Chicago was $3.93/MMBtu, up 5% from a year earlier.

Price volatility make whole payments, intended to encourage suppliers to follow dispatch instructions, rose steeply, with day-ahead payments rising four-fold to $40.3 million for the winter and real-time payments rising 57% to $3.2 million.

The cumulative outage rate was 9.5%, up from 7.3% in 2013/14 and 8.1% in 2012/13. Short-term forced outages, which the Monitor said can be an indicator of physical withholding, rose to 2.7% from 1.7%. The Monitor said it was investigating outages that contributed to shortages or severe congestion, as well as units that didn’t respond on Jan. 6 and 7.

Actions Taken

MISO spokeswoman Jennifer June Lay said the polar vortex “taught MISO and our member companies a number of lessons about how to maintain reliable operations as we face extreme cold weather.”

She highlighted several changes since last winter:

Voluntary Load Management reporting was implemented in July to provide MISO more accurate data. “MISO lacked a clear understanding of demand response availability on a consistent basis due to the seasonal variation in potential and poor visibility into voluntary load management activities,” Lay said.
A real-time display was added to the MISO control centers to show the status of the major pipelines in the MISO footprint. In addition, a gas pipeline notification page was added to the MISO website in August. It includes a list of critical pipeline notices impacting the MISO footprint with drill-down functionality to additional information, including a map of the affected pipelines and the generators they serve.

Lay said the ISO is also discussing potential initiatives to address fuel-supply issues for natural gas units, reduce outages and improve data collection on outages and derates.

MISO is also soliciting stakeholder feedback on a straw man proposal it presented in August to change the natural gas nomination schedule.

State Briefs

Lawmaker: UP Needs Plants, Not Transmission Upgrades

State Rep. Scott Dianda thinks utilities should build new power plants to replace retiring generators in the remote Upper Peninsula, rather than bringing in power over new transmission lines.

Dianda introduced a resolution encouraging the build-out of new power plants to serve the Upper Peninsula, saying it would be more cost-effective than transmission lines. Dianda pointed to the imminent retirement of a 450-MW We Energies plant at Presque Isle as evidence of the need for new generation. The aging coal plant remains operating under an order from MISO, which determined the plant had to stay online to preserve system reliability.

BPU Orders Third-Party Suppliers Provide Simpler Offer Details

The Board of Public Utilities ordered third-party electricity suppliers to explain their offers to consumers in plain language. The order was a response to a flood of complaints from customers who were hit with large bills last winter.

Suppliers now are required to clearly tell consumers if they are getting a fixed rate or a variable rate. Many customers said they were unaware of provisions in their contracts that pegged their electric bills to natural gas prices, which soared during the winter. The changes are to go into effect next month.

“This is really an evolving process,’’ BPU Commissioner Joseph Fiordaliso said. “It is important the industry become involved in the educational process. We didn’t expect this sustained cold.’’

No Need for NCUC Hearing for New Plant, Owners Say

The developers of a new, 475-MW natural gas plant have asked the Utilities Commission to expedite approval of the project because it is unopposed.

NTE Carolinas wants to build a one-on-one combined-cycle plant called the Kings Mountain project in Cleveland County. It has already won approval from NCUC staff. There have been no opposition filings to the project since it was announced in June. If approved, NTE said construction would begin in June of 2015 and operations would start in March of 2018.

UNC Assigning Profs to Duke Ash Study Group

The University of North Carolina is putting together a panel of experts to review Duke Energy’s plans and procedures to close its ash ponds and dumps across the nation, part of an effort to hold the company accountable after a devastating ash spill in the Dan River earlier this year.

The National Ash Management Advisory Board will be chaired by UNC professor John Daniels, an environmental engineer known for reuse of waste materials. The board, which is funded by Duke, will provide guidance to the Duke team overseeing the ash disposal plan. Duke has 33 impoundment ponds and dumps throughout the state holding fly ash from coal-fired generation stations.

Sunoco’s Mariner East Pipeline Given Utility Status by PUC

The Public Utility Commission rejected an advisory opinion and reaffirmed public utility status for Sunoco Logistics Partners and its proposed pipeline, Mariner East. The PUC sent the issue back to administrative law judges to examine Sunoco’s request for a zoning exemption to construct buildings around valve control and pump stations along the 300-mile pipeline.

Sunoco Pipeline is repurposing an existing pipeline to move Marcellus Shale liquefied natural gas to a terminal near Philadelphia, a process that requires new pump and valve control stations on the 83-year-old pipeline. Sunoco had asked that the pump stations be exempt from local zoning restrictions. Some landowners and local governments had hoped to impede the project through zoning hearings.

Two PUC administrative law judges recommended rejecting Sunoco’s status as a public utility, which is the basis for obtaining the local zoning exemptions, but the PUC said the pipeline company qualifies.

“Sunoco’s amended petitions adequately plead sufficient facts for the commission to find that it is both a ‘public utility’ and a ‘public utility corporation,’” the commission wrote in a 4-1 ruling.

DEP Seeks Record Fine Against Shale Gas Driller

The Department of Environmental Protection is seeking a $4.5 million fine against a Pittsburgh natural gas producer for allowing fracking wastewater to leak from impoundments. If the fine is upheld, it would be a record for the state.

The DEP charged that EQT allowed a “major pollution incident” in 2012 in Tioga County. It said EQT first noticed a possible leak in April, but the company said it discovered the leak in May and that it took steps to contain it and dispose of contaminated soil. The DEP, however, said the spill continued to cause problems and that water was still being collected at the site.

Other drillers have faced DEP fines for similar issues. In September, Range Resources agreed to pay a $4.15 million fine related to wastewater contamination.

Exelon-Pepco Merger Gets OK from SCC

The State Corporation Commission last week approved the merger between Exelon and Pepco Holdings Inc., one more hurdle crossed for the $6.8 billion deal. The approval was needed because Pepco and one of its subsidiaries, Delmarva Power and Light, have some transmission facilities in Virginia.

The merger still needs regulatory approval from Maryland, D.C., New Jersey and Delaware, as well as the Federal Energy Regulatory Commission. Pepco stockholders approved the merger on Sept. 23.

Exelon is promising reliability improvements for all Pepco territories, as well as a $100 million customer benefit fund that can be applied toward rate credits, energy-efficiency programs and assistance programs. Exelon is also promising to contribute $50 million to charitable organizations in Pepco territories.

McAuliffe’s Energy Plan Has Something for Everyone

Gov. Terry McAuliffe’s new energy plan casts a wide net, promising support for renewables, new traditional energy projects, coal exports and infrastructure investment. The state rolls out an energy plan every four years.

The plan calls for easing restrictions on solar development and boosting renewable energy. Virginia now only counts about 6% renewables as part of its generation mix, most of that hydro. The plan also calls for a revenue-sharing plan for any gas and oil extracted from offshore development, as well as additional incentives to develop wind energy.

Recognizing that domestic demand is declining for the state’s coal resources, the plan calls for increasing exports of coal and coal technology.

The plan drew initial praise from industry and environmentalists. “We appreciate and agree with the governor’s commitment to an all-of-the-above energy strategy and his recognition of the need for new energy infrastructure investments,” Dominion spokesman David Botkin said. The Sierra Club’s Virginia chapter saw “a lot of good stuff in this plan on efficiency, offshore wind and solar,” according to chapter Director Glen Besa.

State Accepting Bids to Drill Under Ohio River

The state is looking for ways to deal with tight budgets and has hit upon a new one.

Last week, the state opened bids to drill under a 14-mile section of its portion of the Ohio River. Officials from the Department of Commerce say that allowing drilling on state land and now under a state-controlled river would generate $17.8 million in up-front payments, plus royalties.

Until horizontal drilling methods were improved, such extraction wasn’t feasible. But now, allowing fracking under rivers “creates what could be a substantial revenue stream at a time when budgets are very tight,” according to Commerce Secretary Keith Burdette. State officials said other river tracts could be next.

AEP to Transfer Partial Ownership of Mitchell to Wheeling Power

American Electric Power, consumer groups and energy-efficiency advocates have reached an agreement that will let the company transfer half ownership of the 1,600-MW Mitchell Power Plant to subsidiary Wheeling Power.

According to a filing with the Public Service Commission that outlines the terms of the agreement, Wheeling would pay about 82.5% for half of the interest in the plant, with the final payment set in 2020. The agreement, if approved by the PSC, would leave state rate payers responsible for half of what had been a merchant plant, leaving them open to some market risk.

AEP wanted to transfer ownership to a regulated utility in order to obtain rate guarantees. An attempt to transfer partial ownership to Appalachian Power, which is regulated by the Virginia State Corporation Commission, was turned down by Virginia regulators.

To make the deal more palatable for consumer groups and energy-efficiency advocates, AEP promised to bulk up its annual spending on energy-efficiency programs from $1.8 million to $10 million. The company will also issue RFPs for any new generation it may need in the future. This would encourage participation by renewable-energy producers, offsetting criticism that AEP’s generation mix consists of too much coal.

Constellation, Comverge Merging Demand Response Businesses

By Ted Caddell

Constellation Energy and demand side management specialist Comverge said last week they are combining their demand response businesses for commercial and industrial customers.

The announcement came the day before PJM proposed ways for demand response to comply with an appellate court ruling in the Electric Power Supply Association’s (EPSA) challenge of the Federal Energy Regulatory Commission’s Order 745. (See related story, Awaiting FERC Action, PJM Floats ‘Trial Balloon’ on DR Post-EPSA.)

Despite the uncertainty following the EPSA decision, Constellation and Comverge said they believe there is still gold to be mined in the DR market.

The two companies said the new combined business will be operated as a standalone company, with Constellation taking a minority stake and private equity investment firm H.I.G. Capital holding the majority. Terms of the agreement were not released. Comverge, which went public in 2007, was acquired by H.I.G. for $49 million in 2012.

Comverge and Constellation officials said the name of the new company will be announced after the closing of the transaction.

Scale

Comverge CEO Gregory Dukat said the new company’s “size, focus and years of expertise helping C&I [commercial and industrial] customers successfully participate in demand response programs make it a formidable presence in the market.”

Mark Huston, president of Constellation Retail, said DR customers will “benefit from a company solely dedicated to DR products and services.”

Comverge has more than 5.5 million energy management devices in the field and thousands of C&I customers. They also brought more than 1 million residential customers into various DR programs. It has absorbed other demand response businesses, including Enerwise Global Technologies, which it acquired in 2007 for $75 million.

Jason Cigarran, Comverge’s vice president of marketing and communications, said that because the new company will be taking what had been Comverge’s C&I customers, the rest of Comverge will now concentrate on residential and small business exclusively. He declined to say how many megawatts of DR the company has under its control.

Constellation’s retail businesses serve more than 100,000 commercial customers and more than 1 million residential customers. It purchased CPower, which managed 850 MW of DR capacity, in 2010. Constellation said it controlled 1,300 MW of DR as of the end of 2013.

Competition

The merger will give the combined company more scale to compete against publicly traded EnerNOC, which has between 24,000 and 27,000 MW of peak load management. According to a recent Securities and Exchange Commission filing, EnerNOC had $22.1 million in revenue in 2013, about 45% of that from the PJM market.

NRG Energy is also moving into the market in a larger way and now has about 2,000 MW of demand management load under its control.

Some analysts say that the increased competition in the DR market is putting pressure on prices. The loss of the guaranteed prices that had been afforded by FERC’s Order 745 may also slow some of the demand response market, they say. A study by Greentech Media predicted the loss of Order 745 will reduce the annual growth rate of the DR industry from 8% to 4.9% through 2023.

Exelon Selling Utah, Texas Plants to Private Equity Firm

By Ted Caddell

Exelon, which last month announced it would spend $500 million to build two natural gas-fired generating stations in Texas, is selling two other gas plants in Texas and Utah.

An Exelon spokesman confirmed the pending sales last week but declined to give sales prices.

Exelon is selling its five-unit, natural gas-fired peaking plant near West Valley City, Utah, to Wayzata Investment Partners. The 185-MW plant went into operation in 2001 and was folded into Exelon’s fleet in the 2012 merger with Constellation Energy. Investment news service The Street, citing unnamed sources, estimated the price at between $74 million and $93 million.

Starwood Energy Group is buying the second Exelon plant, the Quail Run Generating Station near Odessa, Texas. It is a six-unit, 488-MW natural gas-fired combined-cycle plant. The first section of the plant went online in 2007 with the second section going operational a year later.

It too came with the Constellation merger. Constellation acquired it in 2010 for $365 million.

Exelon Generation spokesman Jimmy Porch said the company expects to close on both in the fourth quarter of this year.

Wayzata did not issue any announcements about the purchase agreement. The company describes itself on its Web site as a private equity firm “that specializes in purchasing distressed companies and assets with various strategies to profitably turn them around in partnership with new or existing management.”

The company, headquartered in Wayzata, Minn., has purchased power plants before. It bought Guadalupe Power, a 1,070-MW plant in Guadalupe County, Texas, in 2011, selling it to Calpine in February.

Starwood has numerous holdings in natural gas and renewable generation and transmission. It also declined to give a purchase price.

Exelon has made steady investments in its generation footprint in Texas, starting when it bought the Handley and Mountain Creek generating stations from then-TXU for $443 million in 2002. Exelon also built a gas-fired plant to serve industrial users near Houston called ExTex Laporte.

Last month, it announced it was building two 1,000-MW gas-fired combined-cycle plants, one each at its existing plants at Wolf Hollow, near Fort Worth, and Colorado Bend, southwest of Houston. That would bring the company’s Texas fleet to about 5,500 MW after the sale of Quail Run.

Porch said Exelon had not intended to sell Quail Run but that it “received attractive unsolicited bids” for the plant. “All decisions were founded on optimizing Exelon’s generation mix,” he said.

He said Exelon remains committed to being a player in the ERCOT market.

“Exelon’s decision to build two new natural gas power plants in Texas is part of our ongoing growth strategy and will allow the company to offer more low-carbon electricity to the growing Texas energy market,” Porch said. “Texas is an important area for growth for Exelon because of the increasing demand for electricity in the state and excellent market conditions.”

He wouldn’t say if there are any other deals afloat. “Exelon continually evaluates all opportunities to add value for our shareholders, including M&A,” he said. “However, we don’t comment on rumors about specific M&A activity.”

PJM Forgoing $10M in Settlement with DC Energy, Scylla

By Michael Brooks

PJM will forgo $10.2 million in balancing operating reserve (BOR) charges resulting from transactions that two trading companies characterized as internal bilateral transactions (IBTs) under a settlement approved by the Federal Energy Regulatory Commission.

PJM, which contended DC Energy and Scylla Energy mischaracterized the transactions to avoid paying the charges, collected $38.8 million in retroactive payments from the companies after it found in 2011 that the trades did not involve the physical transfer of energy and could not be classified as IBTs under PJM’s Tariff. Unlike increment offers (INCs) and decrement bids (DECs), IBTs are not subject to BOR charges.

Under the settlement, PJM will retain the money it has already collected while dropping its claim to the remaining $10.2 million. The companies, meanwhile, will withdraw their petition to the D.C. Circuit Court of Appeals to review FERC’s March 2012 order that forced the companies to pay the charges.

PJM and the companies said they settled “in order to bring certainty to the marketplace and avoid the costs, risks and uncertainties of continued litigation.”

‘Nonsense’

PJM’s Independent Market Monitor, however, said “the argument that the settlement brings certainty to the marketplace is nonsense.” The monitor said the settlement means that PJM members will not receive $10.2 million to which FERC has found they are entitled. It also said, however, that “more than $10.2 million is at stake in this proceeding. Full enforcement of the commission’s orders is important to discourage inappropriate market behavior.”

FERC ruled that the settlement doesn’t change the commission’s interpretation of PJM’s rules concerning IBTs. “PJM market participants, therefore, remain on notice that IBTs may not be used to avoid deviation charges,” FERC said.

PJM Hoping Testing Makes the Difference Before Winter

By Rich Heidorn Jr.

While pondering the biggest change in the capacity market since its inception, PJM is hoping that testing of little-used generating units will ensure they are available if cold weather strains its reserve margin.

Last winter, the RTO saw as much as 22% of its generation on the disabled list as it set new winter peak records. Officials had to admit afterward that they had mistakenly assumed that natural gas plants’ outage rates would be randomly distributed rather than correlated with cold weather and pipeline problems.

The record-setting cold pushed PJM’s load-weighted LMP to $126.80, more than three times the price in January 2012. Operators had to resort to demand response and a voltage reduction to avoid shedding load. The new winter peak of 141,500 MW exceeded the Feb. 5, 2007, mark by nearly 5,000 MW.

It was a humbling experience for an organization long held out as the gold standard among grid operators.

PJM officials responded with an ambitious — and controversial — plan to add a new Capacity Performance product. (See Lower Penalties, More Flexibility in Revised PJM Capacity Performance Proposal.) PJM wants the changes in time for next year’s auction for delivery year 2018/19.

To improve operations in the interim, PJM stakeholders embarked on initiatives in at least five committees and task forces. Earlier this month, the Operating Committee approved plans for voluntary generator testing, while the Market Implementation Committee approved rules to reduce uplift and ensure energy prices better reflect operator actions. (See MIC Briefs)

PJM hopes to test up to 1,000 MW of generation on each of 20 days in December 2014. The tests would be limited to generators that haven’t run in the prior eight weeks and days when temperatures are below 35 degrees Fahrenheit.

The OC also endorsed manual changes to ensure generators keep their operating parameters (e.g., notification times, dual-fuel capability and availability, fuel inventories, resource limitations) updated in eMkt.

PJM officials also have taken steps to improve communication with pipelines, transmission owners and neighboring reliability coordinators.

PJM will enter the winter with 183,000 MW of installed capacity, almost 50,000 more than the projected 50/50 winter peak of 133,510 MW. It will also benefit from transmission upgrades in Pennsylvania, New Jersey, Ohio and Maryland.

The RTO will conduct a fuel inventory survey in November and a dispatcher training webinar covering the changes in December. An emergency procedures drill is scheduled for Nov. 17.

“Based on forecasts, we expect to have adequate power supplies for the winter,” PJM spokesman Ray Dotter told RTO Insider. “We’ve learned from last January’s cold weather and we’re working with our members to improve the availability of generation over the long term.”

“We didn’t have a reliability problem last year. I’m not expecting to have one this year as well,” Executive Vice President for Operations Mike Kormos told the Organization of PJM States annual meeting last week.

One item that remains unresolved on PJM’s to-do list is a potential increase in the $1,000/MWh offer cap. None of three proposals considered by the Markets and Reliability Committee last month could muster a two-thirds majority. (See Members Deadlock on Change to $1,000 Offer Cap.)

Gas and electric futures prices are up sharply, Federal Energy Regulatory Commission staff said in a briefing last week. As of Oct. 1, the average of January and February 2015 contracts at Transco Zone 6 non-NY was $9/MMBtu, almost double last winter. Electricity futures at the PJM Western hub were up 62% to $73/MWh.

PJM Taking Part in FERC, NERC Review of Grid Recovery Plans

PJM is one of nine Registered Entities that has agreed to take part in a review of grid recovery and restoration plans.

The Federal Energy Regulatory Commission announced it and the North American Electric Reliability Corp. will conduct a joint staff review to assess the grid’s bulk power system recovery and restoration planning and determine the effectiveness of NERC reliability standards in maintaining reliability.

FERC spokesman Craig Cano said nine REs, intended as a “representative sample” of the grid, have agreed to participate in the voluntary review. Although FERC declined to identify the participants, PJM spokesman Ray Dotter told RTO Insider that PJM was among them.

Cano said the review is intended as a “proactive” look at the grid’s ability to recover from extreme weather, bulk power system disturbances and cyber or physical attacks. It will include a comparison of the REs’ plans, as well as recommendations based on the identification of good industry practices.

FERC emphasized that the review “is not a compliance and enforcement initiative.”

Storms, blackouts and the threat of cyber or physical attacks “have highlighted the potential to cause widespread adverse effects on the bulk power system,” the joint FERC-NERC data request says. “Effective system recovery and restoration plans are essential to facilitate a quick and orderly recovery in the aftermath of such events.”

The review will focus on the following NERC standards: EOP-005-2 System Restoration Plans from Blackstart Resources; CIP-008-3 Cyber Security – Incident Reporting and Response Planning; and CIP-009-3 Cyber Security – Recovery Plans for Critical Cyber Assets.

NYISO: ‘Well Prepared’ for Winter

By William Opalka

If you want to see the value of dual-fuel capability, look no further than New York, where 47% of the generation can run on oil or natural gas.

That flexibility helped NYISO meet its winter load — including a new winter peak of 25,738 MW — without resorting to voltage reductions or other emergency operating procedures.

On the Jan. 7 record-setter, NYISO imported power from ISO-NE and Ontario over the evening peak, issued public calls for conservation and deployed demand response for the first time in winter.

“The primary operational issues during the first three winter 2014 cold snaps were cold-weather equipment issues and gas-only generator outages,” according to a NYISO review.

The ISO said the extreme cold reduced pressure in high-voltage circuit breakers, caused icing in rivers serving hydroelectric plants and froze pipes and valves.

Although the ISO reported no outages from fuel supply shortages, gas price spikes sent wholesale electricity prices skyward. On 18 days in January, gas prices exceeded oil generation. Like PJM, the ISO obtained a waiver from the Federal Energy Regulatory Commission to pay suppliers costs exceeding $1,000/MWh.

Most oil-fired plants were replenished by barge or truck deliveries at rates close to their burn rates. In late January, however, concerns about oil depletion led to increased NYISO efforts to manage projected unit capability on alternate fuels.

Despite the challenges, ISO officials express confidence heading into winter 2014/15.

“The combination of approximately 18,000 MW of dual-fuel generation in the fleet and our continuing work to enhance communications and operational coordination between the electric and gas industries has us well prepared for the coming winter,” NYISO spokesman David Flanagan told RTO Insider.

The ISO cannot afford to be sanguine, however. Its gas-fired production nearly doubled between 2004 and 2012, and natural gas and dual-fuel generators represent more than 70% of proposed capacity in the ISO’s interconnection study queue.

The ISO established the Electric and Gas Coordination Working Group in January 2012, and in October 2013 it released a study comparing the cost of dual-fuel capability to firm pipeline transportation under several scenarios.

In August the ISO outlined its Fuel Assurance Initiative, a stakeholder process to ensure sufficient generation on days with “a high risk for a reduction in real-time resource availability due to factors such as interchange and fuel supply uncertainty.”

The initiative is expected to consider energy, ancillary service and capacity market changes. Possible energy and ancillary market changes include the creation of “critical” operating days and two recommendations in the Market Monitor’s 2013 State of the Market Report: allowing suppliers to submit day-ahead offers that more accurately reflect fuel supply constraints, and requiring generators to provide information on a daily basis regarding fuel availability.

Leading up to this winter, the ISO said it completed a fuel survey of all gas, oil and dual-fuel-capable generators and is coordinating with pipelines on outages and maintenance.

The ISO said it will begin discussing possible capacity market changes — including incentives tied to performance on critical operating days and the possibility of using separate forced outage rate estimates for summer and winter — this fall.

In 2015, the ISO hopes to complete development of shortage pricing rules.

Increased gas pipeline capacity, relatively mild weather this summer and increased supplies of gas from the Marcellus Shale fields have eased pricing pressures.

The Federal Energy Regulatory Commission’s Division of Energy Market Oversight (DEMO) expects about 1.1 Bcfd of pipeline capacity to begin operation this winter to serve the New York market. The additional capacity could reduce pipeline utilization in New York from peaking at nearly 100% of capacity last winter to about 60% during the coming one, FERC staff said in a presentation to the commission last week.

Prices at the Algonquin citygate near Boston and the Transco Zone 6 New York City pricing point have been below Henry Hub since April, with Transco at $2.34/MMBtu as of Sept. 30, a 38% drop from a year ago. The unusual negative basis was caused by a 38% annual growth in Northeast production and low natural gas demand over the summer.

Long Term

Concerns about a potential “generation gap” that arose more a decade ago have receded somewhat as the state added more than 10,000 MW, mostly wind and gas, between 2001 and 2014. Retirements over the period totaled almost 6,000 MW.

Since 2012, however, the state’s surplus generation versus peak demand and reserve requirements has dropped from more than 5,000 MW to about 1,900 MW.

Planning Committee Briefs

Enhanced inverters serving solar generators and other asynchronous generation will be required to modify their active power in response to system frequency under new rules approved by the Planning Committee Thursday. The rules would also require inverters to autonomously provide dynamic reactive support.

The rules would only apply to new generators.

The Markets and Reliability Committee will hear a first read of the new rules at its Nov. 30 meeting. PJM hopes to win stakeholder approval in time to file the rule with the Federal Energy Regulatory Commission in February.

Manual 14A Changes

The committee approved changes to Manual 14A that create a pre-application process for new and existing generation resource additions of 20 MW or less in compliance with FERC Order 792. Potential interconnection customers will have to submit a formal written request and a $300 processing fee. PJM is requesting these changes be effective beginning Nov. 1. (See PC Starts Work on Small Generator Interconnection Changes.)

Installed Reserve Margin

The committee approved leaving PJM’s Installed Reserve Margin at 15.7% for planning year 2018, unchanged from 2017.

A preliminary reserve requirement study shows the need for a 0.1% increase based on the PJM load shape and another 0.1% from capacity model changes. But these increases are offset by a 0.2% expected increase from imports under PJM’s capacity benefit margin.

PJM is currently analyzing how the new Capacity Product proposal would affect its calculation of its forecast pool requirement (FPR). PJM calculates FPR using the IRM and the average XEFORd, which is the average EFORd excluding outside management control events (OMCs). The proposal would change the definition of an OMC event to make it more restrictive. PJM staff said that they expect the FPR to be slightly lower as a result of the changes.

Md. Advocate Wants Tougher Energy-Efficiency Targets

By Michael Brooks

Maryland’s Office of People’s Counsel is recommending that regulators set tougher energy-efficiency targets for the state’s utilities, which it says are winding down their efforts.

Utilities have largely met their goals under the 2008 EmPOWER Maryland Energy Efficiency Act, which requires them to reduce electricity usage and peak demand by 15% of 2007 levels by 2015.

That’s good news for environmentalists and consumers. But according to a report by the OPC’s consultant, Vermont Energy Investment Corp., that has led to a reluctance by the utilities to continue their energy-efficiency efforts beyond what is mandated.

“While their motivations for this fact may not all be similar, VEIC suspects that a primary driver is that the 15% goals set in the 2008 legislation have come to their natural conclusion, and the utilities have for the most part met those goals,” the OPC said in a letter to the Maryland Public Service Commission. “Without a clear goal established to take the place of the 2008 legislative goals, there is nothing compelling the utilities to expand their efforts.”

Based on VEIC’s report, the OPC is recommending that the PSC direct the five utilities identified by the legislation – Baltimore Gas and Electric, Delmarva Power & Light, PEPCO, Potomac Edison and the Southern Maryland Electric Cooperative – to achieve an average annual net savings rate of 2% of 2012 residential retail sales in its 2015-2017 plans.

According to the report, Delmarva, Potomac Edison and SMECO have already met their 2015 savings goals, while PEPCO is “on track” to meet its goal. BGE, which has by far the highest goal of 3.5 million MWh, has saved nearly 2 million MWh. (See DR at Home: EmPOWER Maryland.)
