NRG is top bidder for SunEdison projects NRG Energy expects a bankruptcy court judge to approve on Thursday its purchase of an assortment of renewable projects from SunEdison for $188 million.

The purchase and sale agreement, or PSA, is for 2,100 MW of SunEdison’s utility-scale solar and wind assets located in the US, which include 200 MW of construction-ready, fully contracted solar assets in Texas. NRG Energy will take an equity interest in a structured partnership that owns 683 MW of “nearly complete, fully contracted” solar assets in Utah and 1,250 MW of solar and wind assets in various stages of development at locations across the country, including Hawaii.

“The PSA provides for total consideration up to $188 million, comprised of an initial payment of $129 million and payment of $15 million upon the execution of designated power purchase agreements for certain assets in development, and up to $44 million in future payments contingent on achieving other development milestones,” NRG said in a statement.

SunEdison filed for reorganization under Chapter 11 of the US Bankruptcy Code in the US Bankruptcy court for the Southern District of New York on April 21. The firm retained the financial advisory group Rothschild to help it sell as much as 3,100 MW of operating wind and solar assets located in the US, India, Chile and South Africa, plus a pipeline of roughly 1,000 MW of capacity under construction and another 1,000 MW planned. Several sales have been announced.

NRG owns 3,733 MW of renewables In an earlier filing with the court, Craig Cornelius, senior vice president of renewables for NRG Energy, said the company agreed to acquire the equity interests in the SunEdison assets for $144 million in cash, “plus up to an additional $43.8 million in potential earn out payments to SunEdison.” Cornelius said NRG agreed to the “replacement of certain credit-support obligations of SunEdison.”

NRG bills itself as “the largest competitive power generation company” in the US, with 50,000 MW of fossil, nuclear, solar, and wind

SunEdison’s affiliate, the yieldco TerraForm Power, did not enter bankruptcy. However, analysts now say that an auction of SunEdison’s 51% stake in TerraForm Power is looming. On Tuesday, equity analysts at Macquarie Research said they believe an auction of SunEdison’s stake in TerraForm “should begin any day now.”

On August 8, SunEdison and a number of its affiliates asked the bankruptcy court to approve a stalking horse agreement with NRG. It asked that an auction be held on an expedited basis. The company was concerned that the value of its businesses could decline if the auction was delayed.

NRG’s stalking horse proposal set a floor for the value of the equity interests, and for the past month SunEdison was able to entertain higher bids during a brief go-shop period.

However, on September 12, SunEdison confirmed that NRG was the winning bidder in the auction. The deal now must receive approval from the bankruptcy court at a hearing that is scheduled for September 15.

It owns 667 net MW of wind generation at 24 wind farms and 585 net MW of solar generation at seven facilities, including a 50.1% stake in the 392 MW Ivanpah concentrating solar thermal facility located in the Mojave Desert in California.

Its affiliate, NRG Yield, owns and operates an additional 482 net MW of utility-scale solar generation at ten facilities, and 1,999 net MW at 19 wind farms, including 100% of the 947-MW Alta Wind farm in Tehachapi, California.

MISO AVERAGE REAL TIME LMPS, HENRY HUB SPOT PRICES 35

One of the key assets in NRG’s deal with SunEdison is the 200-MW Buckthorn Solar farm that is ready for construction in Pecos County near Fort Stockton in West Texas. The central Texas town of Georgetown, which decided to rely entirely on renewables for its power, signed a 25-year PPA with the affiliate developing Buckthorn in May 2015.

The project, which was expected to be completed by the end of 2017, has been delayed.

SunEdison was anxious to expedite the auction process in large part to avoid a default on Buckthorn’s PPA with the City of Georgetown.

In an August 9 filing with the court, a Skadden, Arps, Slate, Meagher & Flom attorney for SunEdison said the company “must move with haste to attract other viable bidders before the value of the business declines further. Specifically, the Buckthorn Project faces an April 2017 commercial operation date, which is the date upon which a project is completed and begins production of electricity for sale.

“Failure to reach COD by October 25, 2017 would constitute a termination event under the applicable power purchase agreement,” the filing said, “and daily delay damages between the scheduled COD of April 28, 2017 and the final COD of October 25, 2017 are significant.”

In order to meet the final COD and obtain construction financing, the Buckthorn Project owner must issue a final notice to proceed “by the end of September 2016 — or, at the latest, early October 2016.”

“Should the FNTP not be timely issued and the COD not ultimately reached, it is unlikely that the debtors will be able to monetize the Buckthorn Project and obtain value from that project for their constituents,” the filing said — Jeffrey Ryser

MISO's low prices in alert cause 'concern': IMM Low power prices on a day when the Midcontinent Independent System Operator declared a maximum generation event "caused a little concern" for some stakeholders, the independent market monitor told a key panel Tuesday.

During Tuesday's meeting of the Markets Committee of the MISO Board of Directors, David Patton, president of Potomac Economics, MISO's independent market monitor, noted that on July 21, MISO forecast peakload at 125 GW and declared a maximum generation event, which means the entire footprint has a generation shortage.

In such an event, known as a Level 2 Energy Emergency Alert, MISO operators can take a sequence of steps, ranging from emergency power purchases from market participants up through deploying interruptible loads and purchasing power from neighboring grid

operators.

However, MISO's peakload forecast was about 4 GW more than actual, as storms in the Great Lakes area reduced temperatures in those areas and market participants voluntarily curtailed load by about 1.6 GW, Patton said. As a result, the maximum real-time energy price that day was about $36/MWh, he said, compared with $192/MWh on July 25, when no such emergency conditions existed.

"It caused a little concern among some people that on the hottest day in the year we had low prices," Patton said.

ELMP system deems no emergency capacity needed Emergency pricing rules called for MISO to apply a proxy offer floor price for all emergency power, but they did not set prices, partly because the Extended Locational Marginal Pricing system deemed no emergency capacity was necessary. Therefore, the 195 gas turbines MISO committed were more than necessary, which incurred a revenue sufficiency guarantee uplift charge of more than $1.6 million, Patton said.

Formerly known as "convex hull pricing," the ELMP model includes start-up costs in LMPs for fast-start resources and uses offline faststart resources in price formation under scarcity conditions. It was implemented in March 2015.

MISO's ELMP software allows fast-start resources that are scheduled at limits or offline to set price, which has resulted in some price increases, but Patton said too few of MISO's online peaking resources are eligible under the ELMP model's protocols.

In contrast, the ELMP system's use of offline fast-start resources in price formation has caused price decreases, Patton said, and the net effect over the summer was a price decrease of 1 cent/MWh. Real-time LMPs averaged $30.75/MWh in August compared with

$29.73/MWh in July and $28.55/MWh in August 2015, according to a written report by Todd Ramey, vice president for system operations and market services. Ramey attributed most of the price strength to increased demand driven by higher temperatures.

Cooling degree days up 23% from summer 2015 Load totaled 65.5 TWh in August, up from 65.4 TWh in July and 62.6 TWh in August 2015, Ramey reported.

This June-July-August was hotter than those months in the previous two years and the average of the prior decade, Patton said.

Cooling degree days this summer were 23% higher than last summer, Patton said.

But another factor in August's higher prices may have been the lack of wind generation, which totaled 2 TWh this August, compared with 2.5 TWh in July and 2.4 TWh in August 2015, according to Ramey's report.

Wind supplied 7% of MISO's energy in 2015 up from 6% in 2014, while coal supplied 52%, down from 58% in 2014; natural gas supplied 23%, up from 17% in 2014; and Nuclear supplied 15%, down from 16% in 2014, according to Potomac Economics' latest State of the Market Report for MISO, which was issued in June.

Coal prices were flat month to month but lower year over year, according to Ramey's report. Powder River Basin coal averaged $1.36/ MMBtu this July and August, compared with $1.51/MMBtu in August 2015.

Spot natural gas prices across the large MISO footprint were mixed.

The Chicago City-gate spot price averaged $2.75/MMBtu in August, essentially flat with July's $2.73/MMBtu, but down from August 2015's $2.86/MMBtu. At the Henry Hub, spot natural gas averaged $2.80/ MMBtu this August, compared with $2.79/MMBtu in July and $2.78/ MMBtu in August 2015. — Mark Watson

Proposed Michigan utility faces roadblocks A proposal by Wisconsin's WEC Energy Group, one of the largest electric utilities in the Midwest, to create a new utility to build and operate natural gas-fired generation in Michigan's Upper Peninsula is running into potential roadblocks.

Michigan Attorney General Bill Schuette, in a new filing with the Michigan Public Service Commission, is recommending WEC's application to form the Upper Michigan Energy Resources Corp.

(UMERC) be denied.

The request is premature because there are "too many unanswered questions about the power supply options" available to WEC and other parties that have not been "adequately analyzed and vetted," Sebastian Coppola, an independent consultant for the Republican attorney general, testified.

The PSC staff, too, questioned aspects of the proposal.

Utility plans development of gas plants Foremost is whether the new utility's planned development of 170 MW of gas-fired generation in the UP over the next few years would be sufficient to replace WEC's 431-MW Presque Isle baseload coal plant on the shore of Lake Superior near Marquette.

Assuming timely formation of the new utility, WEC is seeking a final PSC order before the end of 2016, construction on what likely would be two small gas-fired plants in the Upper Penninsula is expected to begin in 2018, with the generation on line in 2019, prior to Presque Isle's closing. The likely gas plant locations have not been made public.

The establishment and operation of new generating facilities in the sparsely populated and transmission-challenged region is aimed at resolving long-term reliability concerns related to Presque Isle's planned retirement and would preclude the need for additional and unnecessary transmission costs borne by Michigan ratepayers, according to officials.

The attorney general cited the lack of fuel diversity as one of the concerns about UMERC constructing new gas plants as its main source of power supply.

"Natural gas prices have been and could potentially be very volatile in the future," Coppola warned. "The potential run-up in gas prices in future years as more power plants convert to natural gas and the current excess supply of natural gas diminishes presents a real risk of escalating power costs."

Such a risk is significant, he added, "when the new power plant, which is dependent on natural gas prices, will be the main or only source of power supply to UMERC. It does not appear that UMERC will have a diversified source of power supply after the new power plant begins operations."

Plant financing could pose risk The new utility's ability to finance the new gas plants estimated to cost about $255 million also was called into question.

UMERC, Coppola noted, would be a small utility with approximately $84 million of net assets. Yet, it would be asked to finance a project costing a quarter of a billion dollars, or triple its worth.

Coppola said he asked if WEC would provide any financial support or guarantees and was told "it is too early to determine the most appropriate methods to finance the project and a number of financing options would be available to UMERC." As a result, Coppola said it appears earlier statements that UMERC would finance the project were "premature or simply a stated desire."

He concluded the application should be denied "at this time or until the joint applicants present in a clear and transparent fashion the cost of all available options in order to demonstrate that the recommended course of action is in the best interest of the Michigan Upper Peninsula customers."

In a Tuesday interview, WEC spokesman Brian Manthey pointed out Cliffs Natural Resources has agreed to enter into a 20-year power purchase agreement to buy electricity from the new gas plants for its iron ore mines in the Upper Penninsula.

The PSC staff said it is unclear if construction of the new gas generation would allow for Presque Isle to be retired without the need for additional infrastructure in order to provide safe, reliable and adequate energy services to the Upper Penninsula.

"The proposed new generation is significantly smaller than the existing [Presque Isle] plant and the interconnection locations are not solidified," staff said.

ERCOT prices fall despite peakload record August demand in the Electric Reliability Council of Texas region set a new peakload record as prices came in as much as 40% below last year with natural gas taking a larger share of the fuel mix.

Peakload demand set a new all-time record of 71,093 MW on August 11 and actually broke the 2015 record several times throughout the month. ERCOT’s final Seasonal Assessment of Resource Adequacy projected demand to peak this summer at 70,588 MW. August’s power demand was up 5% from 67,445 MW in July and increased 1.7% from 69,877 MW in August 2015, ERCOT said in its monthly usage report released Friday.

Despite increased demand during the month, National Weather Service data shows that Austin, which lies near the center of ERCOT's footprint, had 7.5% less cooling degree-days in August than normal and 6.6% less than from 2015.

Natural gas-fired generation increased to 49.1% of the fuel mix in August, the highest it’s been since March; that’s up from 45.6% in July but down from 51.2% in August 2015. Houston Ship Channel spot natural gas prices averaged $2.734/MMBtu for August, up from the averaged $2.713/MMBtu average in July, but down from $2.736/MMBtu in August 2015.

Coal-fired power inched up to 31% of generatin in August, compared with 30.7% in July and 29.8% in August 2015. Nuclear provided 10.2% of generation, up from 9.7% in July and 10% in August 2015.

Wind output in August slipped to 9.4%, down from 13.8% in July but up 8% from last year.

South Hub on-peak averaged $37.60/MWh in August, an increase from $31.42/MWh in July, but down from $59.97 in August 2015.

West Hub on-peak prices averaged $35.50/MWh in August, moving up from $30.79/MWh in July but sinking from $58.97/MWh in August 2015.

Currently, ERCOT North Hub October packages are valued in the upper $20s/MWh, down from the same time last year, when October 2015 prices averaged in the higher $20s/MWh. October 2015 values averaged $28.50/MWh in September 2015 trading, starting the month around $28.40/MWh, reaching as high as $29.70/MWh and rolling off the curve at $27.45/MWh. Consumers across the grid operator's footprint used 36.46 million MWh in August, down from 36.97 million MWh in August 2015 – a 1.4% year-on-year decrease, according to the report. Usage fell roughly 4.6% from 38.22 million MWh in July. — Kassia Micek

Hot summer fails to boost PJM peakload

ERCOT day-ahead locational marginal prices increased month on month but fell year on year.

At ERCOT North, the most liquid hub, day-ahead on-peak prices averaged $36/MWh in August, up from $31.86/MWh in July but down from $58.95/MWh the year-ago month.

Houston Hub on-peak day-ahead averaged $40.20/MWh in August, up from $35.04/MWh in July, but down from $60.78/MWh in July 2015.

This summer was hotter than the previous three summers in the PJM Interconnection service territory, but systemwide peakload was lower than the highest peakload for those years, and PJM staffers are unsure why.

During Tuesday's PJM Operating Committee meeting, Chris Pilong, PJM dispatch manager, presented a written overview of PJM's operations in the period from June through August 2016, which was hotter than the same three-month periods of 2013, 2014 and 2015, judging by the number of cooling degree days at various cities around the PJM footprint. PJM's service territory stretches as far west as Chicago, as far east as New Jersey, as far north as the Pennsylvania shores of Lake Erie and as far south as eastern North Carolina.

The National Weather Service reported that this summer's CDD total for Pittsburgh, which lies near the geographic center of the PJM footprint, was about 52% above normal and about 36% above summer 2015 levels.

Total load this June through August, at 226.6 TWh, was larger than total loads during the summers of 2013 through 2015, Pilong said. The largest June-through-August total over the previous three years was 216 TWh in the summer of 2013.

PJM had 23 hot weather alerts this summer, while the top number of such alerts for the previous three summers was 16 in 2015. Between 10,000 and 13,000 MW of generation was unavailable during this

summer's hot weather alerts, Pilong reported.

However, the systemwide peakload this summer, 151,293 MW on August 11, was about 4% less than the systemwide peakload in the highest peakload for 2013-2015, which was 157,509 MW on July 18, 2013.

PJM West price lower than previous summers Also, the average day-ahead on-peak locational marginal price at the PJM West Hub was just $36.23/MWh this June through August, compared with $37.83/MWh in that period of 2015, $43.49/MWh in that period of 2014 and $46.53/MWh in that period of 2013, according to the Platts price database.

Possible contributors to the lower peakload this summer include behind-the-meter solar power and distributed energy resources, Pilong said. Other possibilities include conservation efforts and more efficient air conditioning, lighting and television.

Virginia transmission outage planned The Operating Committee also learned that a transmission line of about 50 miles in length between Cunningham, Virginia, and Elmont, Virginia, northwest of Richmond, Virginia, would be out of service from October 23 through June 2, 2017 and from September 6, 2017 through December 30, 2017. A rebuilt 500-kV line is slated to go into service by June 1, 2018.

The outage is not likely to reduce generation capacity, but it may cause minor thermal overloads and low voltages in the area, stakeholders were told.

FERC approves Tucson Electric coal plant deal Tucson Electric Power will buy 214 MW in a coal-fired unit in Arizona for $85 million under a deal conditionally approved by the Federal Energy Regulatory Commission.

In its Monday order, FERC rejected TEP’s contention that the planned deal wouldn’t harm competition and didn’t raise any horizontal market power concerns (EC16-96).

To eliminate the chance that TEP could exercise market power by its growing stake in the 1,755-MW Springerville power plant, FERC ordered the Fortis utility to sell at least 125 MW of capacity and energy during winter peak hours to an entity that lacks a market presence in TEP’s balancing authority area. TEP, which owns about 2,763 MW, pledged to deliver the power to the Palo Verde hub.

The requirement will end when the coal-fired San Juan Unit 2 near Farmington, New Mexico, is retired by December 31, 2017. TEP owns 170 MW in the unit.

The planned transaction will settle litigation around the Springerville power plant’s 425-MW Unit 1 near Springerville, Arizona.

TEP has a 49.5%, or 210 MW, stake in the unit. The rest of the unit is owned by Alterna Springerville LLC and LDVF1 TEP LLC. In 2014, Alterna and LDVF1 filed a complaint about their leases in the Springerville unit at FERC. The commission rejected the complaint and the dispute is pending in the U.S. Court of Appeals for the Ninth Circuit. The suit was put on hold while TEP, Alterna and LDVF1 worked out a settlement agreement.

Even with the increased coal capacity from the planned Springerville transaction, TEP and its sister utility UNS Electric plan to get 30% of their electricity from coal-fired resources by 2030, down from 80% in 2014, according to a mid-July update to the utilities’ integrated resource plan. Their renewable generation is expected to go from 4% to 30% over the same period.

TEP is considering exiting the San Juan Unit 1 in July 2022, according to the resource plan. The utility has a 170-MW stake in the unit.

The utility could also exit the coal-fired Navajo Generating Station where it owns 168 MW in December 2030, the resource plan update said. Six months later it could exit the Four Corners power plant, where it has a 110-MW stake.

FTR values rise on high-priced negative deals Market value for prompt-month financial transmission rights (FTR) obligations in all grid operators’ markets for September 2016 showed a modest increase relative to August amid higher-priced negative contracts.

Total contract volume in the September auctions was 165,817 GWh, down 5,896 GWh from August, but up about 5,305 GWh, or 3% from September 2015. Absolute market value of the cleared contracts totaled $86.03 million, a 2% increase from August’s market value, but about 8% below the value of cleared contracts from a year ago,

according to data from the seven independent system operators.

FTRs — also known as congestion revenue rights, transmission congestion contracts, and transmission congestion rights in some markets — are financial instruments that allow market participants to hedge against congestion on the electric grid. An FTR obligation contract entitles the contract owner to either be charged or receive compensation when there is congestion between specific points on the grid in day-ahead electricity markets.

Negative purchased contracts support market

ICE

Average contract values in the September auctions were mostly down month over month across the different contract classes, with negative buy contracts being the only class posting an increase in prices. Volume-weighted average prices for negative buy contracts increased 17 cents, or 38%, month over month. The more expensive contracts helped sustain a higher market value compared to August, but wasn’t enough to boost overall market value above September 2015 levels.

Volume-weighted average prices for positive contracts, both buys and sells, were down 21% and 27%, respectively. Negative sell contracts were also down month over month, with volume weighted prices averaging 23 cents, or 27%, lower compared to August.

Compared to September 2015, all contract classes recorded similar movements, with negative buy contracts being the only class with premium prices.

With FTRs, a positive price means that the contract buyer had to pay the ISO for the contract. A negative price means that buyers are being paid by the ISO to take on the risk of congestion in the opposite direction of the historical prevailing path flow.

For negative contract prices, movements were mixed across the board, with three ISOs posting price increases and four posting lower prices relative to contracts in the August auctions. Like the positive contract class, negative contracts in ERCOT also exhibited the most significant increase month over month with weighted average prices coming in 105% higher relative to August. Elsewhere, MISO and SPP were the other two ISOs with higher negative prices. Coming in with lower prices were Cal-ISO, ISO-NE, NYISO, and PJM.

Company eyes PURPA enforcement in Connecticut Windham Solar is again bringing its gripes with Connecticut's implementation of a Jimmy Carter-era electricity market policy to FERC, filing its third petition within the past year for enforcement against the state.

The latest petition (EL16-115) comes as the Connecticut Public Utilities Regulatory Authority issued a final decision August 24 denying Windham's request for a power purchase agreement for several solar facilities of 1-2 MW in size.

The Public Utility Regulatory Policies Act requires utilities to purchase power from small renewable power plants and other qualifying facilities at the full avoided cost of replacing that power with other generation. States are empowered to tailor their own avoided cost rules, providing a limited exception to FERC's exclusive authority over wholesale power sales.

Windham in January sought to sell energy and capacity from 26 solar facilities to Eversource, the Connecticut utility where those facilities interconnect. Windham opted to exercise its rights under 18 CFR §292.304(d)(2)(ii), offering a 30-year contract for energy and capacity at the utility's forecasted avoided costs.

The facilities at issue are in advanced stages of development and most have garnered approval from the Connecticut Siting Council.

Most of the solar units have also already executed interconnection agreements, with Windham having paid Eversource $1.8 million under interconnection agreements to connect the projects, the solar developer told FERC. Eversource, however, refused to purchase the energy and capacity from the QFs, prompting Windham to petition the Connecticut Authority.

Under PURPA, FERC has the authority to enforce the statute's requirements on state commissions when requested by generators, and can even take state commissions to federal district court to enforce those requirements.

But enforcement actions are rare as the commission generally relies on voluntary compliance or has let the parties themselves engage in the litigation, even when a violation of PURPA was found.

Legally enforceable obligation rebuffed for intermittent resources Windham urged action in this case, asserting that the Connecticut

Authority's decision denying its request for a PPA improperly implied that states and non-regulated utilities should be given deference in regards to the formation of a legally enforceable obligation.

"The term 'legally enforceable obligation' is a federal law provision, not a state law provision. As such it must be uniformly interpreted and applied," Windham said.

Yet, Connecticut utility regulators "held that intermittent generators are not entitled to a legally enforceable obligation," Windham said, citing language in the final decision that "only QFs that can guarantee a particular quantity of power at a particular time can avail themselves of the option to calculate avoided costs at the time the obligation is incurred."

Windham asserted that filing suit with a federal district court "would be particularly appropriate here because the commission has addressed the issue of a state commission prohibiting a QF from a legally enforceable obligation because it is an intermittent resource in JD Wind, [a 2010 FERC order] which eventually ended with the [5th US Circuit Court of Appeals'] clearly erroneous decision in Exelon."

That 2014 ruling by a divided panel of the 5th Circuit found that it was within the Texas Public Utilities Commission's discretion to limit legally enforceable obligations to firm power because neither PURPA nor FERC regulations implementing the law addressed the issue (Exelon Wind 1, LLC v. Nelson, 12-51228). The decision created a

precedent for a state to limit the ability of intermittent resources to sell power under PURPA. The ruling "represents a fundamental misunderstanding of energy contracting," and the "case is a paradigm of what can happen when a court, which is not an expert in the subject matter, decides a case on a basis that no party raised or briefed," Windham said.

"Now the Exelon virus has spread to Connecticut, and without firm commission action, it will undoubtedly spread to other states," Windham contended in its plea for FERC to act.

Windham calls for invalidating Connecticut rules According to Windham, the Connecticut Authority also reasoned, in finding that Eversource did not have to buy energy from Windham's QFs, that generators in deregulated states are not entitled to long-term forecasted rates calculated at the time an obligation is incurred, and that "it is unjust and unreasonable [under PURPA] to require a utility to enter into a long-term contract when it has an all-requirements supplier."

In ruling that Eversource did not have to purchase capacity from Windham's QFs, the Connecticut Authority found that "because [ISO New England] arranges for capacity requirements and bills Eversource for such requirements, Eversource has no direct need for capacity" and that "costs that Eversource may save from reduced charges from ISONE for capacity are not considered an avoided cost under the commission’s regulations," Windham said.

Lastly, the Connecticut Authority held that "it is unjust and

NY crys foul over ISO-NE capacity proposal An aspect of a proposal to boost liquidity in ISO New England's forward capacity market could annually increase costs for New York power consumers by hundreds of millions of dollars if its implementation is not delayed by a year, warned New York's grid operator, utility regulators, transmission owners and large energy consumers in the state.

New York Independent System Operator filed a protest with FERC Friday, challenging ISO-NE's plan to broaden participation by import capacity resources in its forward capacity auction (FCA).

The plan is part of ISO-NE's so-called forward capacity market enhancements designed to give market participants more opportunities to secure or shed capacity supply obligations (CSOs) following the region's annual three-year-forward capacity auction.

Tariff revisions (ER16-2451) proposed August 19 would also allow new resources to compete to procure a CSO earlier than currently possible and would introduce an option for seasonal bilateral contracting.

NYISO said it had no objections to those two elements of the proposal. But the narrow issue of capacity imports that did trigger concern was "critically important" as it could cause "material pricing inefficiencies."

But these "potentially severe economic consequences for New York consumers can be avoided if the NYISO is allowed a reasonable time to make needed market rule changes to address capacity exports from constrained capacity areas in the New York Control Area," the grid operator said.

unreasonable for ratepayers to have to assume the risk of inaccurate forecasting for energy or capacity," Windham's petition to FERC asserted.

Windham asked FERC to "enforce PURPA in federal district court in order to invalidate the various Connecticut rules announced in the final decision." The company also asked that the rules be permanently enjoined.

FERC, in a notice issued Tuesday, opened Windham's petition for enforcement to public comment through October 3. Per typical procedure, FERC will review the petition and any comments or protests filed, and issue a notice of intent either to act or not to act within 60 days of the petition being filed.

A notice of intent not to act would clear the way for Windham to initiate litigation if it so chooses, while a notice of intent to act means that at some point FERC would go to court to enforce PURPA. Windham noted in the petition its right to file suit in federal district court to force the state to properly comply with PURPA.

NYISO called for implementation of the import proposal, with respect to generators in New York only, to be deferred by one capacity year so that it would first apply to capacity commitments beginning June 1, 2018.

The City of New York and an unincorporated group of 60 large industrial, commercial and institutional energy consumers with

manufacturing and other facilities in the state filed comments in support of NYISO's position. They said a postponement or deferral of the implementation of the elements of ISO-NE's proposal at issue would not impact resource commitments made for 2018-19 nor would it detract from the substantive merits of the import proposal.

The New York State Public Service Commission also filed comments backing the one-year delay to the effective date of the import proposal as it pertains to capacity exports from New York.

"The requested delay would not impede the ability of resources located in other control areas to export capacity to ISO-NE," the PSC said. "It would, however, enable the New York capacity market to avoid a pricing inefficiency that, according to NYISO estimates, would needlessly inflate capacity prices by potentially more than $200 million."

ISO-NE holds FCAs each February for CSOs that require power suppliers to be able to deliver capacity for a year-long period three years in the future. This capacity commitment period starts the June 1 three years after the FCA is held and runs through the following May 31.

Between the FCA and the start of the capacity commitment period, ISO-NE holds annual CSO bilateral windows, where suppliers can get out of a CSO by selling it to a qualified counterparty at a price agreed upon by the parties, followed several months later by an annual reconfiguration auction, another opportunity to relinquish or compete for CSOs. The aspect of the tariff revisions irking New Yorkers would align market rules applied to import capacity resources with those for generators and demand response resources. Specifically it would allow imports backed by external resources to participate in reconfiguration auctions and CSO bilateral contracting for the second and third early capacity commitment periods, held two years and three years, respectively, after the corresponding FCA. The revised qualification requirements for import capacity resources to participate in the reconfiguration auctions would take effect October 19, under the proposed tariff revisions.

NYISO said such an effective date "creates a substantial risk of unjustifiably increasing New York capacity prices and creating inefficient price signals in the NYISO-administered capacity market."

David Patton, president of Potomac Economics, NYISO's independent market monitoring unit, explained in an affidavit that NYISO's tariffs and procedures currently do not specify how a generator in NYISO's footprint that has sold capacity to a neighboring

region but would still have capacity available for dispatch to meet some local reliability needs should be treated in NYISO's planning process and capacity market.

"By default, the resource will be treated as if it no longer exists, which is inconsistent with operational reality," Patton said.

NYISO market rule changes needed before proposal takes effect NYISO believed it had until June 1, 2018, to address this problem as that is when capacity from the Roseton generating station in southeast New York that cleared ISO-NE's FCA 9 for the 2018-19 planning year was supposed to begin to be exported.

Patton contended that "under the current market rules, allowing a generator in a NYISO locality to begin exporting capacity in June 2017 could result in inefficient capacity cost increases in the NYISO’s 2017-18 capability year of as much as $341 million."

He explained that the cost increases would be the result of the NYISO's auction clearing as if Roseton no longer existed in the state's load zones G-J. NYISO said it was already in the early stages of formulating a solution to the inefficient outcomes its market rules would produce by not accounting for the continued operation of resources exporting capacity from New York localities.

"The issue is extremely complex, however, and an appropriate solution must address a range of issues, which include capacity market design changes, the calculation of capacity market requirements, generator obligations, New York State Reliability Council requirements, NYISO software requirements, and related timing issues," it noted.

The grid operator therefore asked FERC to defer implementation of the import proposal for one capacity year for generators in New York localities. NYISO said such relief was "tailored … as narrowly as possible to minimize disruption to ISO-NE's proposed market enhancements."

NYISO added that it "would attempt to fashion an immediate market rule change to try to avoid pricing inefficiencies" if its request for deferral of the proposal at issue is denied.

A group of New York transmission owners filed a similar protest arguing that FERC must consider the effect of ISO-NE's proposal on neighboring regions when making a determination on the justness and reasonableness of the tariff revisions.

Platts’ compilation, analysis of FTR auctions Platts each month compiles and analyzes data from the seven financial transmission rights auctions held each month by regional transmission organizations. FTRs are a hedging tool to protect market participants from the risk of congestion on the grid between specific points, which is reflected in higher prices.

Generally, companies that want to protect themselves against day-ahead congestion costs buy positive or prevailing-flow contracts that pay out if there is congestion. Also sold in auctions are negative or counterflow contracts, for which FTR holders receive a payout in the auction but are required to pay if there is congestion in the day-ahead market. Several ISOs also allow participants to sell back their existing FTR contracts in the auctions. Auction activity can be described in terms of the total volume and price of FTRs cleared in the auction, as well as in terms of positive and negative flow FTRs, and the net volume and value of contracts sold—net positive contracts (positive and zero-priced FTRs purchased by market participants and negative FTRs sold by market participants) minus net negative contracts (negative FTRs purchased by market participants and positive and zero-priced FTRs sold by market participants).

The graphs and tables are based on data from the individual RTO auctions and include only trading of FTR obligations for the prompt month. Some RTOs offer multiple time periods during their monthly auctions as well as options contracts, but those types of FTRs are not included in this feature.

Some market participants have multiple affiliates which trade FTRs. The data has been consolidated, combining entities from the same parent company, umbrella company or organization.
