MISO Board of Directors Meeting Briefs

NEW ORLEANS — MISO will commence its long-term Clean Power Plan analysis in July regardless of the existing Supreme Court stay, Clair Moeller, executive vice president of transmission and technology, told the Board of Directors last week. Moeller said the RTO would provide individual state data to officials in all states, including those having placed a “hard stop” on CPP preparations.

FERC Chairman Norman Bay, who attended the board meeting, said he hoped MISO states challenging the CPP and halting compliance work had a “Plan B.” He also thanked the RTO for its “uniquely constructive and pragmatic voice” in supporting the measure.

“We know we’re on a glide path already with low-cost wind turbines, lower-cost solar panels and greater efficiency,” board member Tom Rainwater said. He asked how the economics of renewable penetration would play out even if the CPP is struck down.

Moeller called that one of the more complicated questions MISO would seek to answer through remaining modeling, saying the RTO’s “job is to plan into an uncertain future.”

Bay said that if analysts are correct in predicting a 50% decline in the cost of storage by 2020, storage technology could be a “game changer” for renewable penetration.

“Everyone knows the cost of energy storage will decline,” Bay said. “It’s a question of how much and when. … This is an area where I expect FERC to do more work and work to remove barriers to entry.”

MISO YTD Financials 1% Over Budget

MISO’s year-to-date February financials came in $400,000 — or 1.1% — over the RTO’s $36 million budget for the period.

Most of the overage — $300,000 in additional costs for “compliance and process-improvement activities” is a permanent variance, said Vice President of Finance Jo Biggers, who said MISO was seeking to trim other spending to make up for the shortfall.

“We’re still forecasting to be on budget by the end of the year,” Biggers said.

Board member Paul Bonavia noted that the board had “only just finalized the budget, and we already have a permanent variance.”

“We’re going to figure out a way to cover it by reducing costs somewhere else,” MISO CEO John Bear told the board.

The overrun occurred despite MISO spending only $6 million of its forecasted $7.1 million capital budget, mostly because of project delays. Biggers said capital spending is expected to fall in line by the end of March when projects catch up to their timelines.

MISO Adds Transmission Developers, Industrial Customer Group to Membership

MISO’s board unanimously approved membership applications for three non-transmission owning entities, including:

  • Cobra Industrial Services, a Houston-based transmission developer;
  • Transmission developer PPL TransLink, a unit of Pennsylvania-based PPL; and
  • Louisiana Energy Users Group, an association of 23 industrial customers.

MISO Proposes Adding Forward Auction for Retail Choice Zones

By Amanda Durish Cook

NEW ORLEANS — Deregulated markets in MISO would get a three-year forward capacity auction beginning in 2018, under a proposal unveiled by the RTO last week.

Forward Capacity Auction - Retail Choice Zones - Dynegy's Baldwin Energy Complex in IL
Dynegy’s Baldwin Energy Complex in MISO

The RTO announced the proposal after reviewing stakeholder recommendations for addressing the capacity needs of retail choice regions such as southern Illinois’ Zone 4. (See PJM-Type Capacity Auction for MISO Zone 4 Proposed.)

“It is now evident MISO’s markets … need to effectively and efficiently signal the need to maintain existing and/or invest in new resources necessary to assure resource adequacy in competitive retail areas that rely exclusively on markets,” MISO said. “Given the existing [Planning Resource Auction] was not designed to meet this need, narrowly focused reforms are required to complement the existing market construct while also preserving the benefits currently derived by most of MISO’s region from simple capacity balancing.”

The proposed Forward Local Requirements (FLR) auction would be held three years in advance of the planning year and employ a downward sloping demand curve. Procured local capacity would be self-scheduled into the existing PRA with costs allocated pro rata to participating load-serving entities.

LSEs not subject to retail choice will continue to procure capacity through state integrated resource plans and the PRA using the current vertical demand curve.

“These enhancements are designed to have no impact on the existing state or local jurisdictional long-term planning processes for those that do not participate,” MISO said. “The effect will be that nonparticipating LSEs and participating LSEs will have different price sensitivities to purchasing … capacity in the auction.”

Design Elements

The RTO proposed to hold the first FLRAs in spring 2018 for planning years 2019/20 through 2021/22. The amount of capacity retail choice LSEs obtain under the sloped demand curve would be variable, within a newly defined “target reliability range.” Any capacity needs not met through the forward auctions will be filled through the existing prompt-year capacity auction.

While LSEs in deregulated areas would be automatically entered into the FLRA, they could opt out by developing a fixed resource adequacy plan in advance of the auction. LSEs outside of deregulated areas could opt-in to the forward auction but would be required to remain for at least five years.

Participation will be voluntary for supply resources except for those in a local resource zone with participating demand. Such resources will be subject to existing market power rules.

Supply resources owned or controlled by LSEs will be exempt from the must-offer requirements if the LSEs have forecasted demand equal to or more than their supply portfolios.

Seasonal Construct

The forward capacity product would match the two-season construct MISO proposed in December for the PRA, with a four-month summer season (June-September) and eight-month winter (October-May). The RTO hopes to implement the seasonal structure for the 2018/19 planning year. (See MISO Delays Seasonal, Locational Capacity Constructs.)

MISO officials said the RTO is committed to working with stakeholders to refine the new auction proposal. “I think the key is keeping that stakeholder dialogue going, and we’ll continue that in the April Resource Adequacy Subcommittee,” MISO CEO John Bear said.

In a recent letter to stakeholders, MISO Executive Director of Market Design Jeff Bladen wrote, “The goal is to ensure MISO’s capacity market design is up to the task of serving as the primary market mechanism for assuring resource adequacy in all time horizons in competitive retail areas of the MISO region while also serving a complementary role in the rest of MISO.”

MISO plans to file a final proposal with FERC in July, according to Bear.

UPDATE: Exelon Closes Pepco Merger Following OK from DC PSC

By Suzanne Herel

Exelon closed its $6.8 billion acquisition of Pepco Holdings Inc. on Wednesday, after the D.C. Public Service Commission approved the merger 2-1 on terms it crafted itself.

Two years in the making, the deal will rank Exelon as the largest utility in the country by number of gas and electricity customers.

Pepco shares gained $5.71 (27%) to $26.95 on the news, while Exelon shares lost 28 cents (-0.8%). Pepco stockholders will receive $27.25/share in the deal. PHI’s common stock was removed from the New York Stock Exchange on Thursday.

Pepco’s three operating companies will retain their local headquarters: Atlantic City Electric in Mays Landing, N.J.; Delmarva Power in Newark, Del.; and Potomac Electric Power Co. in D.C.

D.C. also won additional concessions: Exelon will move the offices of the CFO and the chief strategy officer to the district along with that of Pepco Energy Services, which is now in Arlington, Va. David Velazquez will assume the role of president and CEO of PHI, a post previously held by Joseph Rigby, who is retiring.

“Today, we join together as one company to play a vital role as a leader in our industry and the mid-Atlantic region,” Exelon CEO Chris Crane said in a statement. “We’ve made a number of commitments to customers in all of the Pepco Holdings utilities’ jurisdictions — the district, Maryland, Delaware and New Jersey — and we look forward to getting to work to deliver those benefits to our customers and communities.”

An Exelon spokesman said the D.C. agreement triggers the “most favored nation” clauses in the other states’ contracts, and it will be returning to those state regulators to “true up” benefits.

So far, Exelon has committed $430 million for ratepayer credits, reliability improvements and other investments for customers in Pepco’s service territories.

DC PSC Lifeline

dc psc, exelon, pepco, exelon-pepco merger

Many had expected the deal to fail, after the most recent proposal by Exelon and Pepco was rejected by all but three of the other settling parties.

The companies on March 7 asked the commission to consider three options: Revisit its rejection of the settlement agreement brokered by the administration of Mayor Muriel Bowser; adopt the revised proposal by Commissioner Joanne Doddy Fort; or accept a third alternative that would give the PSC more latitude in how to spend money from the $72.8 million customer investment fund on rate relief. (See Exelon-Pepco Deal Doubtful as DC Officials Reject Alternatives.)

Fort and Commissioner Willie Phillips voted to approve the second option; Chairwoman Betty Ann Kane dissented.

Fort’s proposal took Bowser’s deal and added changes regarding the use of the CIF, the development of a 5-MW solar generation facility at the Blue Plains Advanced Wastewater Treatment Plant and the role of Pepco in establishing public-purpose microgrids.

The Bowser-brokered deal had earmarked money from the CIF for a handful of D.C. groups, including the Sustainable Energy Trust Fund, the District of Columbia Consumer and Regulatory Affairs Green Building Fund and the Low Income Home Energy Assistance Program.

The PSC’s counteroffer takes those funds, totaling $32.8 million, and places them in an escrow account to pay for projects to modernize the district’s energy system and for energy efficiency and energy conservation initiatives focused on housing for low- and limited-income residents. The PSC would have authority over the funds’ disbursement.

In her dissenting opinion, Kane said that developments in the record since she voted to oppose the Bowser settlement in February “give me even stronger reasons to find that the takeover of the district’s electric distribution company by a multi-faceted, vertically integrated, generation-focused holding company … benefits Pepco and Exelon shareholders but does not provide sustainable benefits to district ratepayers, places Pepco within a structure that is contrary to district law and policy and should be rejected.”

Unlike a rate case, she said, the sale of Pepco can’t be reviewed again. “It is gone forever,” she said. “The stated motive of the sellers is to increase PHI shareholder value. The motive of the buyer is to add regulated revenue to prop up Exelon’s failure to pay dividends to its shareholders. However, the needs of Pepco’s customers and the district are for a safe, reliable, modern electricity delivery distribution system at a just and reasonable cost.”

In their order, Fort and Phillips said Exelon’s first option identified no error of law or fact that would warrant a reconsideration of its rejection of the settlement negotiated by Bowser’s office.

It found the third alternative unacceptable for three reasons: It would allocate a $25.6 million base rate credit solely to residential and apartment customers; there was not enough information to determine the implications of the proposed base rate credits; and the shift of funding to rate credits would come at the expense of projects that would make the grid better able to accommodate distributed energy resources.

In offering the settling parties the retooled agreement, the commission already had judged it to be in the public interest.

Fort and Phillips said their revised settlement ensures that the district receives the $72.8 million CIF, which will be used for rate relief, energy conservation programs and projects to modernize the distribution grid and enable it to accept more distributed resources, “thereby further promoting the district’s sustainability agenda.”

“These are all funds that will not be available to district ratepayers or the district if the merger is not approved,” they said, adding that the changes made to the Bowser settlement “ensure that the district’s market remains a competitive one for suppliers who want to bring more renewable energy resources to our city while still requiring Exelon to invest in 7 MW of new solar in the district and 100 MW of new wind” in PJM.

Disappointment and Surprise

DC PSC, Exelon, Pepco, Exelon-Pepco mergerPower DC, a coalition formed against the deal, said, “We are profoundly disappointed and saddened that the D.C. Public Service Commission has ignored the clear opposition to the proposed Exelon-Pepco merger voiced by the district’s elected officials, community and business leaders, and residents.

“By approving the merger, the PSC has exposed our city to decades of higher rates, weakened its own ability to guide our city’s energy future and helped ensure that D.C. will fall behind the rest of the U.S. on clean, efficient energy.”

“I don’t think we’re surprised” at the ruling, said Williams Fields, senior assistant in the Maryland Office of People’s Counsel, which has appealed the Maryland Public Service Commission’s earlier approval of the deal. “It’s been down a long path. We haven’t read the ruling yet. We will have to evaluate on how it impacts Maryland in regards to additional funding from our most-favored-nation status. And, of course, we will have to see how it affects our appeal.”

Montgomery County, Md., Councilman Roger Berliner, who had campaigned against the merger, said in a statement that the merger approval was “deeply disappointing.”

“Its approval now means that Exelon will totally dominate the Maryland market,” he said. “Environmental and consumer interests were needlessly sacrificed. The only winners are Pepco shareholders and Exelon’s bottom line, a bottom line that has been hammered by its huge investment in nuclear power.”

David Bonar, Delaware’s Public Advocate, said he was “pleasantly surprised.”

“I’m glad to see that it is finally resolved. Each jurisdiction has its own idiosyncrasies and partners who have a right to input, and I’m glad they all had an opportunity to add their input,” he said.

“I think the [D.C.] PSC made the right decision. Now, we have to figure out exactly what it means to us in regards to additional funding. It will come out to several millions of dollars. I certainly hope we can give energy users some long-term benefits, like meaningful energy efficiency programs.”

The Apartment and Office Building Association of Metropolitan Washington was the only settling party to file its support of the commission’s revised proposal.

Those opposing it were the National Consumer Law Center, National Housing Trust and National Housing Trust-Enterprise Preservation Corp., the D.C. Office of the People’s Counsel, the Bowser administration and the D.C. Water and Sewer Authority.

They took issue with the PSC’s requirement that $25.6 million of the CIF earmarked for residential rate relief be held in escrow until the next Pepco rate case and then be considered for disbursement, including to nonresidential customers.

“Despite the commission’s perplexing approval of a proposal that OPC and most of the other settling parties rejected, the Office of the People’s Counsel is fully prepared to continue to aggressively advocate for ratepayers and fight to ensure that rates remain affordable for consumers, particularly for our most economically vulnerable residents,” People’s Counsel Sandra Mattavous-Frye said.

The NCLC and the NHT were the only settling parties to voice support for the companies’ third alternative.

“Should option three be rejected, the merger is likely to collapse,” they said. “From the perspective of NCL/NHT, this is contrary to the public interest and particularly contrary to the interests of low-income households in the district.”

The General Services Administration, the largest consumer of electricity in the district, had not signed on to the settlement negotiated by Bowser but had voiced concern that the included rate relief would not be disbursed to non-residential customers. It initially supported the commission’s revised proposal, which addressed that issue, but on March 17 filed comments urging the PSC to reject Exelon’s filing.

Exelon has spent an estimated $259 million over the past two years trying to capture Pepco’s $7 billion rate base.

“Should option three be rejected, the merger is likely to collapse,” they said. “From the perspective of NCL/NHT, this is contrary to the public interest, and particularly contrary to the interests of low-income households in the district.”

The General Services Administration, the largest consumer of electricity in the district, had not signed on to the settlement negotiated by D.C. government, but had voiced concern that the included rate relief would not be disbursed to non-residential customers. It initially supported the commission’s revised proposal, which addressed that issue, but on March 17 filed comments urging the PSC to reject Exelon’s filing.

The first option proposed by the companies should be rejected because it did not include grounds that the commission’s rejection was “unlawful or erroneous.” The second should be dismissed because it was not approved by all of the settling parties, as the PSC required. The third should be refused as either a petition for reconsideration or a new settlement agreement that would be subject to normal commission proceedings, it said.

Exelon has spent an estimated $259 million over the past two years trying to capture Pepco’s $7 billion rate base.

CEO Chris Crane said in a Feb. 3 earnings call that the company was prepared to immediately begin buying back the 57.5 million shares it issued for the $6.8 billion deal if the merger fell through.

The uncertainty of the merger has taken a toll on Pepco’s stock. In late afternoon trading, it was down 52 cents (2.37%) at $21.45. Exelon shares have remained largely unaffected. In late afternoon trading they stood up 30 cents (0.85%) at $35.18.

Market Policies, Emissions Goals on Collision Course in New England

By William Opalka

BOSTON — ISO-NE market rules favoring natural gas are on a collision course with state and federal environmental mandates, speakers at the EUCI US/Canada Cross-Border Power Summit said Tuesday.

Left to itself, renewable energy advocates said, the market would dictate a shift to natural gas, and only natural gas, ignoring the impact on greenhouse gas emissions.

Backers of gas generation countered that renewables are benefiting from government-backed subsidies and long-term contracts that threaten to reintroduce government-mandated integrated resource planning.

Dan Dolan, president of the New England Power Generators Association, told the conference that state policies are giving renewables undue advantage and undermining conventional generators’ investments in the market.

He cited state-backed long-term contracts that could introduce more than 2,000 MW of Canadian hydropower into the region. “You can’t add that much stuff onto the plate without some of the soup getting spilled over the side,” Dolan said.

In the last two Forward Capacity Auctions conducted by ISO-NE, about 3,200 MW of new gas-fired generation has successfully bid into the market, he said. “Of all those megawatts of cleared resources, not a single one of those has a state-backed long-term contract or other subsidy,” Dolan said.

Francis Pullaro, executive director of RENEW Northeast, which represents renewable energy developers and environmental organizations, said current market rules skew toward natural gas and disadvantage clean energy resources. Natural gas “resources are going to be built over the next couple years with generous capacity payments” that make financing easier to obtain, he said.

Under the FCAs run by ISO-NE, resources are able to lock in prices for seven years. Renewables, Pullaro pointed out, have little capacity value and are only able to obtain financing through long-term contracts, which states have required from the electric distribution companies.

“We really can’t add any more gas to the system than what is already expected to come onto the system over the next few years if we are going to meet our greenhouse gas reduction laws,” he said.

Primary among them is the Massachusetts Global Warming Solutions Act, which requires a 25% reduction in carbon emissions from 1990 levels by 2020. Several New England states have followed suit with similar emission-reduction goals.

To meet its target, Massachusetts Gov. Charlie Baker has proposed a bill, S. 1965, that would allow electric distribution companies to enter into long-term contracts for large hydropower resources and offshore wind.

Janet Besser, vice president of policy and government affairs for the Northeast Clean Energy Council, a trade group for clean energy businesses, said the legislation’s support of offshore wind is “a critical component of the bill.” Wind, combined with hydro resources, could provide firm capacity, especially with a transmission buildout to connect remotely sited resources, she said.

“It’s an overarching policy goal and it is also a goal of customers. They want resources something other than gas … they are not resources being delivered by the market alone.”

The battle for generation market share is unlikely to end any time soon, as the region also faces the prospect that almost 6,000 MW of coal and oil-fired generation that is at least 40 years old will retire in the next few years.

That, observed Ned Bartlett, undersecretary of energy and environmental affairs for Massachusetts, is “enough power to supply Maine, New Hampshire, Vermont and Rhode Island combined.”

FERC Transmission Metrics Report IDs Potential Underinvestment

By Rich Heidorn Jr.

All but one of the organized markets under FERC jurisdiction have regions that show signs of transmission underinvestment, according to the commission’s first transmission metrics report.

FERC’s Office of Energy Policy and Innovation (OEPI) was tasked last year with collecting data to evaluate the impact of Order 1000 and other commission policies intended to encourage competition and infrastructure growth. The research also sought to determine whether regions have “appropriate levels” of transmission infrastructure. (See “Transmission Investment Metrics,” FERC Briefs.)

The staff report identified 13 areas — including every ISO and RTO under FERC jurisdiction except ISO-NE — in which there were persistent high or low prices, suggesting a lack of transmission was preventing load pockets from accessing cheaper generation. Some of the areas — including the Baltimore area and Delmarva Peninsula in PJM, North-Central MISO, the Chicago area, the Upper Peninsula of Michigan and Northern New York — have shown price separations for nine or 10 years.

Regions-with-Persistent-Price-Separations-(FERC) --transmission metrics

The report also confirmed that Order 1000 has unleashed competition, with nonincumbent transmission developers submitting almost half of the proposals received by CAISO and PJM from 2013 through 2015. (Data was not available from other regions such as MISO and SPP, which are just beginning to open competitive windows.)

“One hope in issuing this report is that people will look at the assumptions we’ve made and provide feedback and perhaps ideas for additional metrics,” OEPI staffer Rahim Amerkhail said at the conclusion of a presentation to the commissioners at Thursday’s open meeting.

Below are the metrics and key conclusions:

Percentage of Nonincumbent Transmission Project Bids

Nonincumbents submitted 48% of all competitive transmission project proposals in CAISO’s and PJM’s regional planning processes from 2013 to 2015 (excluding a PJM window that closed last September, for which the RTO had not posted proposals). Nonincumbent proposals accounted for the majority of proposals in all three years in CAISO. In PJM, nonincumbents submitted the majority of proposals in 2013 and 2015, but less than 40% of proposals in 2014.

Staff identified incumbents as those making proposals in their own retail distribution service territory.

Load-Weighted Curtailment Frequency

Staff assumed that persistent congestion in an area suggests there is not enough available transfer capability to deliver power from the cheapest resources.

For RTO and ISO markets, staff looked at LMPs. For non-RTO/ISO market regions in the Eastern Interconnection, staff used NERC transmission loading relief (TLR) data. (Such data was not available for the Western Interconnection, which manages unscheduled flows with schedule curtailments and controllable devices such as phase shifting transformers.) Staff normalized the TLR data based on the region’s retail load.

The data found that SPP, MISO and the Tennessee Valley Authority had the highest levels of load-weighted TLRs.

Although MISO’s and SPP’s markets optimize dispatch based on congestion, reducing their internal use of TLRs, they use the procedure to manage unscheduled loop flows originating outside their footprints. “Both MISO and SPP have extensive borders with non-organized market areas, which may help explain their continuing use of TLRs,” staff said.

The data showed SPP’s TLR rate dropped after the RTO launched its day-ahead market in March 2014.

RTO/ISO Price Differential

This metric shows how long RTO/ISO market nodal price differentials have occurred persistently.

Staff looked at real-time prices at each load and generator point — focusing on the 95th and fifth percentiles of prices rather than maximum or minimum prices — then calculated market-wide average highs and lows to identify locations whose high or low prices were at least one standard deviation from the averages.

Staff found relatively high or low real-time LMPs occurred at 1,986 generator or load points from 2012 through 2014. Thirteen areas had differentials spanning at least three years.

Load-Weighted Transmission Investment

A third set of metrics, which compared transmission investment to load and project sizes, was designed to provide a longitudinal analysis comparing values before and after FERC policy changes took place.

Load-weighted transmission investment averaged more than $2/MWh of retail load over all regions from 2008 to 2014. The highest average investment was in the Texas Regional Entity, at more than $4/MWh across all years, reflecting the $5.7 billion spent in the state’s Competitive Renewable Energy Zone (CREZ), an initiative to alleviate congestion and integrate wind generation.

The smallest load-weighted investments were in the SERC Reliability Corp. and Florida Reliability Coordinating Council regions in the Southeast.

A related metric, load-weighted circuit-miles added, produced similar results.

Circuit-Miles per Million Dollars of Investment

The Midwest Reliability Organization added 1.7 circuit-miles of transmission per million dollars invested, the highest of any region, according to the report. PJM’s reliability region, Reliability First Corp., had the most expensive transmission with less than one circuit mile per $1 million spent. The average was 1.1 miles per $1 million.

The differences “may be due to a range of factors, including terrain, population density, and state policy choices, among others,” staff said.

Company Briefs

TransCanada, spurned in its attempts to push through the Keystone XL Pipeline last year, announced it will buy Columbia Pipeline Group for $13 billion, including the assumption of $2.8 billion in debt. The deal will give it access to the Appalachian shale plays.

TranscanadaSourceTranscanada“The acquisition represents a rare opportunity to invest in an extensive, competitively positioned, growing network of regulated natural gas pipeline and storage assets in the Marcellus and Utica shale gas regions,” TransCanada CEO Russ Girling said. Columbia Pipeline has 15,000 miles of pipelines, as well as underground storage and processing facilities.

TransCanada, which just last month bought the 778-MW Ironwood natural gas-fired generating station in Lebanon, Pa., said it will sell off some of its other generating assets in the Northeast to finance the Columbia deal, including Ironwood. Among its plants are the 2,480-MW Ravenswood Generating Facility in Queens, N.Y., and the 560-MW Ocean State Power station in Rhode Island.

Coal, Alternative Energy Deal with Money Troubles

peabodyenergysourcepeabodyTwo energy companies from opposite ends of the spectrum — coal producer Peabody Energy and alternative energy developer SunEdison — are reporting financial woes.

Peabody reported to the U.S. Securities and Exchange Commission that it probably won’t be in compliance with its financial requirements by the end of the month, and it might have to file for Chapter 11 bankruptcy protection.

SunEdison said problems in its accounting processes led to a delay in its annual stockholders report. It was also dealt a blow this month when it could not secure the financing necessary to acquire rooftop solar company Vivint.

Investors Sweeten the Pot In Cleco Acquisition Bid

clecosourceclecoLouisiana utility Cleco would give a credit of $370 for the average residential and small-business customer, amounting to a free month of electricity this summer, under a proposal to sell the company for $4.9 billion to a consortium of foreign investors. Cleco President Darren J. Olagues said the credit would be paid within 30 days of the closing of the sale.

The state Public Service Commission last month refused to allow investors to purchase the 80-year-old utility that serves about 286,000 customers in southern Louisiana. The investors have requested a rehearing, which the commission will consider this week.

The Cleco coalition, led by Macquarie Infrastructure and Real Assets, and which includes British Columbia Investment Management Corp., has committed to paying $101 million in upfront rate credits.

Sharyland Proposes Tx Upgrade To Meet Wind Energy Demand

sharylandutilitiessourcesharylandSharyland Utilities has filed a request with the Public Utility Commission of Texas for a $77.4 million transmission line upgrade in the Texas Panhandle to accommodate the growth of wind energy in the region.

The project would add a second set of high-voltage lines on 166 miles of transmission infrastructure that Sharyland completed about three years ago. A study by ERCOT, which runs 90% of the Texas grid but not the Panhandle, estimates the area’s wind capacity is 4,300 MW and is growing.

“Given the dramatic and continued expansion of wind generation in the region, Sharyland should proceed with installation of the second circuit,” PUCT Commissioner Kenneth Anderson wrote in a September memo supporting the move.

Peabody Energy Selling Share Of Prairie State Energy Campus

Peabody Energy, fighting to stay out of bankruptcy, is selling its 5.06% share of the Prairie State Energy Campus in Illinois to Wabash Valley Power Association for $57 million. Its original investment in the troubled power plant was $247 million.

The coal-fired plant endured cost overruns and construction delays and is struggling to compete on the open wholesale energy market. The remaining shareholders, mostly Illinois cities such as Batavia and Geneva that own shares through their membership with the Northern Illinois Municipal Power Agency, should not be affected by Peabody’s sale of its shares, a Peabody spokesperson said.

An industry observer, Sandy Buchanan, executive director of the Institute for Energy Economics and Financial Analysis, said municipal shareholders will be left with a large amount of debt that will be a burden on their ratepayers. “All these communities were promised that the cost of power from Prairie State was less than market [price], and the reverse has happened,” Buchanan said.

Report: Aqua America Made Abortive $11B Bid for ITC

Water utility Aqua America apparently made an unsuccessful bid for transmission owner ITC Holdings before the company agreed to be acquired last month by Fortis, according to The Philadelphia Inquirer. The Inquirer quoted from a Fortis merger statement that said “a director of ITC affiliated with Party G, a U.S. publicly traded company, informed [ITC] that Party G might be interested in exploring a potential merger” at a price of about $11 billion.

The only two directors of ITC “affiliated” with public companies, according to the Inquirer, are Aqua CEO Christopher Franklin and Lee Stewart, who is also on the board of a New Jersey plastics maker called AEP Inc. (no connection to American Electric Power). A Wall Street analyst identified Aqua America and Warren Buffett’s Berkshire Hathaway as potential buyers of ITC in a report to investors.

If successful, the Bryn Mawr, Pa.-based company, which runs water and sewer companies in eight states, would have been offering almost twice its own $6.4 billion stock market value. ITC chose instead to be acquired by Fortis, which offered $11.3 billion. Aqua America declined to comment on the report.

Modeling Shows Need for Higher Wind Assumptions

By Amanda Durish Cook

The increase in wind generation under the Clean Power Plan would likely exceed MISO’s previous assumptions and require creation of new renewable generation zones, according to a new analysis from the RTO.

MISO’s midterm CPP analysis, presented to the Planning Advisory Committee last week, also quantified the most economic levels of coal retirements under the EPA rule, showing that the cheapest path to full implementation would require the retirement of 16 to 21 GW.

The analysis showed that MISO’s Regional Generation Outlet Study (RGOS) is in need of expansion, said MISO Senior Policy Studies Engineer Jordan Bakke. The 2009 study sought to help states meet their renewable portfolio standards by identifying regions with optimal combinations of wind conditions and distances to load as well as suggesting potential transmission projects to accomplish the goals.

MISO Clean Power Plan Study Predicts Need for Expanding Renewable Zones

Assumptions Overtaken

The study produced the RGOS zones MISO uses today, with assumptions initially meant to inform decisions until 2026. While actual and queued wind siting has been consistent with those assumptions since 2011, the RTO expects wind installations to begin exceeding projections because the CPP and falling prices mean renewable penetration will exceed levels needed to meet the state renewable mandates on which the earlier study was based.

MISO says the anticipated growth warrants adjustments to the MISO Transmission Expansion Plan renewable siting methodology, as well as adding solar zones into study assumptions.

Bakke said an uptick in renewables is imminent. “In light of the [Supreme Court] stay, the timeline for the CPP is unclear, but in general we’re studying carbon reductions,” he said. “The CPP is only one of many things that are driving carbon reductions.”

To assist its analysis, MISO commissioned renewable planning firm Vibrant Clean Energy (VCE). The company modeled three scenarios: a 30% cut in carbon emissions from 2005 levels by 2030; a 50% emission reduction by 2036; and an 80% cut by 2050.

Among the study’s findings:

  • MISO’s Zone 1 (Minnesota, western Wisconsin and MISO’s stretch of the Dakotas) is ripe for large amounts of potential wind export capacity by 2050. Zone 1’s wind-rich locations make economic sense for extensive wind build-out and transmission development, VCE concluded in the study, which used an assumed $700/MW-mile transmission cost.
  • The Great Lakes region could experience a spike in wind production if more transmission was built in that region.
  • With expanded transmission and the elimination of coal, the MISO grid could handle 217 GW of installed wind generation and 125 GW of solar and generate 861,000 GWh of renewable power by 2050. (MISO’s all-time wind peak is 13.1 GW, set on Feb. 18.)

Wind has a higher capacity factor than solar in MISO’s footprint, making it a more economic option. Bakke noted the VCE study did not include assumptions about distributed generation or energy storage. He said a more complete picture of the study would be presented at MTEP workshops on March 30 and April 28.

Bakke added that MISO’s long-term CPP analysis would deal with the specifics of transmission overlay on a “bus to bus” level. He said MISO hopes to have a new siting methodology finalized with updated wind zones, new solar zones and ozone non-attainment areas by the July PAC meeting.

‘Sweet Spot’ for Coal Retirements

MISO’s midterm analysis also showed that extensive coal retirements would need to accompany wind’s expansion in order to cost-effectively meet CPP standards.

MISO Clean Power Plan Scenario Analysis“We’re not going to try to build our way into compliance by having a very high reserve margin,” Bakke said. “What the system has to do to comply is shift away from coal.”

The analysis set out three scenarios for retiring coal under the CPP through 2034, with the most economic levels of retirements varying based on carbon emissions reductions:

  • Under the “final CPP” scenario unaltered by current legal challenges (a 34% reduction in CO2 emissions from 2005 levels), 16 to 21 GW of coal retirements would be most economic.
  • Accelerated CPP compliance (a 43% decrease in emissions) results in 24 to 30 GW of coal retirements.
  • Partial CPP compliance (a 17% cut in emissions) results in retirement of 8 to 11 GW of coal.

‘Bathtub Curve’

In every scenario, total costs of compliance over the 19-year period exceeded $237 billion. But costs could be considerably higher if too much, or too little, coal retires.

In a scenario with no coal retirements, Bakke explained, MISO would be forced to redispatch from coal to older, more expensive gas plants in order to comply with CPP mandates. Retirements of the least efficient coal units would lead to replacement with newer, more efficient gas plants, driving down production costs.

Still, system costs would amplify if coal retired beyond rates needed to comply with the CPP, as more expensive natural gas and renewables drive costs higher, resulting in what Bakke referred to as a “bathtub curve” on modeling graphs. Bakke pointed out that high costs from too many retirements were unlikely, as generators would not be inclined to over-comply with any final version of the CPP rule.

“The system naturally doesn’t want to retire this much coal,” Bakke said.
