Low Gas Prices, Increased Solar Undercut CAISO 2015 Power Costs

By Robert Mullin

Wholesale power costs in CAISO fell sharply last year as lower natural gas prices, increased solar generation and reduced loads more than offset the impact of a steep decline in hydroelectric output, according to a report from the ISO’s Department of Market Monitoring.

Renewable Generation by Type (CAISO)
Solar output last year surpassed all other forms of renewable generation for the first time since CAISO began operation.

The ISO’s total cost of serving load decreased 31% to $8.3 billion in 2015, compared with $12.1 billion the previous year, the department said. Average wholesale costs dropped to $37/MWh from $52/MWh in 2014.

“Declining gas prices clearly had a role in the decrease,” Keith Collins, CAISO manager of monitoring and reporting, said during a June 7 call to discuss the report.

Collins noted that the 40% decline in California gas costs followed a national trend, with SoCal Citygate and PG&E Citygate prices falling along with the benchmark Henry Hub price. He also pointed out that, controlling for gas prices, CAISO power costs were down only 6% year-over-year, a decrease likely attributable to a sharp rise in output from low-cost solar. Lower congestion and increased virtual supply — which improved convergence between day-ahead and real-time prices — added downward pressure, the department said.

Last year also saw a seemingly contradictory movement between total loads and peak loads, with the former down and the latter up. Collins noted that a September heat wave produced CAISO’s highest annual peak load in five years, up nearly 5% from the 2014 peak.

Total and average load fell slightly for the year, continuing a trend of modest declines since 2012. The department attributed the drop-off to the growth of rooftop solar capacity, which the ISO estimates may have reached 4,000 MW last year.

Grid-connected solar reached a milestone in 2015, surpassing wind to become the largest source of renewable generation in the CAISO system. Solar output increased 38% during the year and accounted for nearly 7% of system energy. Wind output fell slightly, accounting for 5% of total supply. In 2014, solar provided less than 5% of system energy, below wind’s 5.6%.

Geothermal generation also accounted for about 5% of supply, gaining 24% over the previous year. The department attributed the increase to a group of geothermal units formerly outside CAISO’s footprint coming under its control.

In total, non-hydro renewables accounted for 18% of supply — not counting renewable imports — compared with 40% from natural gas and 8% from nuclear. Hydro (5%) and imports (28%) made up the balance.

While NV Energy did not join the CAISO-run Western Energy Imbalance Market (EIM) until the final month of 2015, Collins reiterated the ISO’s observation that the utility’s membership quickly unified what was previously a fractured market. (See NV Energy Has Smooth EIM Integration, CAISO Says.)

“The inclusion of Nevada really changed the dynamic of the market,” Collins said. The increased transfer capacity from NV Energy’s transmission network has significantly improved the link between CAISO and the PacifiCorp East (PACE) balancing area, creating more uniform pricing for imbalance energy, he said.

“We see the optimization creating a one-EIM price for those regions,” Collins said.

Other highlights of the report:

  • Hydroelectric output dropped for the fourth straight year in the face of extreme drought, falling to one-third the 2011 level. Snowpack in the Sierra Nevada mountains — a natural store for run-of-river hydro operations — was at 3% of normal on May 1, 2015.
  • Net imports fell 2% from 2014, mostly because of decreased imports from the Southwest. The department said the drop-off likely stemmed from lower price differentials between Southern California and the Palo Verde trading hub in Arizona.
  • Intervals of negative pricing in Southern California during the second quarter were attributed to combined surpluses of wind and solar generation during a period when outages on the Path 15 transmission line limited flows to the northern part of the state. Negative prices in the 15-minute market occurred in about 4.7% of intervals during that quarter, compared with an average of 2% for the year.

Study: NY Could Manage Sharp Solar Growth by 2030

By William Opalka

New York could accommodate up to 4,500 MW of wind generation and 9,000 MW of solar photovoltaic capacity by 2030 with no system reliability issues, according to a NYISO draft study released last week.

The backdrop to the “Solar Integration Study” is New York’s Reforming the Energy Vision initiative, which promotes adoption of cleaner and more distributed energy resources as well as state incentives that promote rooftop solar generation. New York’s Clean Energy Standard also mandates the state derive 50% of its electricity from renewables by 2030. (See Cuomo: 50% Renewables by 2030, Keep Nukes Going.) The NYISO study focuses on system impacts — rather than the costs or economics — of renewable energy.

new york solar power

A National Renewable Energy Laboratory study this year found that New York has the potential to install 46.4 GW of rooftop solar PV — which represents the upper limit of potential installations rather than a prediction, the study notes.

“The growth of solar PV energy as a source of electric generation is being strongly influenced by various public policy initiatives, including programs established by the State of New York in the State Energy Plan,” NYISO said.

The NYISO study included:

  • Development of hourly solar profiles and a 15-year solar PV projection by zone in New York;
  • “Lessons learned” and integration studies from other regions experiencing significant growth in solar and wind resources;
  • The impact of various levels of solar PV and wind penetration on the state’s grid regulation requirements; and
  • Potential reliability concerns associated with the frequency and voltage ride-through characteristics of solar installations.

The study points out that the $1 billion NY-Sun Initiative announced in 2012 will yield 3,000 MW of solar PV for the state, more than 500 MW of which had been installed by the end of 2015.

“As the penetration levels of solar PV and wind increase, any projected increases in regulation requirements are relatively minor and can readily be accommodated within the current market rules and system operations,” the study says.

The study recommends that NYISO advocate for industry standards requiring solar inverters to have voltage and frequency ride-through capabilities and request that the state establish similar requirements for the non-bulk power system.

NYISO says the study will lay the groundwork for additional research by the ISO.

Ott Restructures PJM Divisions, Leadership

PJM CEO Andy Ott on Friday announced organizational changes that will give additional responsibilities to senior vice presidents Stu Bresler and Vince Duane — a move Ott had foreshadowed following the departure of Executive Vice President and Chief Operations Officer Mike Kormos in March.

Bresler, who has been overseeing the Markets Division, will add the Operations Division, formerly overseen by Kormos, to his duties. Vice President Mike Bryson will continue to lead Operations.

pjm, andy ott

The newly formed Law, Compliance and External Relations Division will report to Duane, the RTO’s general counsel, and include the State & Member Services Division and the Compliance Division, which already had been moved under Duane’s supervision earlier this year. Vice President Denise Foster will continue to lead State & Member Services.

The new division will address legal and regulatory components and oversee communications with various audiences.

“We are making some changes to our structure as our organization continues to grow and evolve,” Ott said. “Our objective with this realignment is to better serve our stakeholders by positioning internal processes — and those conducting them — to better support company strategies.”

The changes will take effect July 6.

Ott was named CEO in October after a six-month transition period at the side of Terry Boston, who retired. (See Boston Retirement Prompts Additional Promotions at PJM).

When PJM announced Kormos’ departure, Ott had said that his position would not be filled. (See PJM COO Kormos Leaving; Post Won’t be Filled.)

New York Debates PPAs or RECs for Clean Energy

By William Opalka

New York policymakers grappled last week to find the most cost-effective way to reach the state’s 50% renewable energy target by 2030 while maintaining a competitive electricity market.

NY State Wind FarmThe New York Public Service Commission held a technical conference June 9 to discuss the state’s proposed Clean Energy Standard, the roadmap intended to transition the state away from fossil fuel — and eventually nuclear — generation (15-E-0302).

“Without question, thinking about how we are going to get new resources into our mix is key to our success,” PSC Chair Audrey Zibelman said.

At the conference, industry stakeholders debated whether power purchase agreements, renewable energy credits or some combination of both would be the best way to achieve renewable goals without exposing consumers to price risks in an environment of low natural gas prices. The state is moving away from the current centralized procurement by the New York State Energy and Research Development Authority.

Under both the PPA and REC approaches, the total payment per megawatt-hour, including energy and capacity, would be set at the start of the project. Under fixed-price RECs, the generator would be exposed to fluctuations in commodity value (energy and capacity revenue).

Under a bundled PPA, ratepayers would accept commodity price risk, with the net program cost determined based on the difference between the PPA and energy and capacity values. “Where at any point in time the value of energy/capacity exceeds the contracted PPA amount, the program cost per megawatt-hour becomes negative (i.e., [load-serving entity] customers benefit from paying the renewable electricity generator less than the market value of energy and capacity),” explained the PSC staff’s cost study, which was released in April.

The study assumed PPAs and RECs would be used equally to procure the 5.2 GW of Tier 1 renewables envisioned by 2023. Those resources would be dominated by land-based wind (38%) and solar power developed under the NY-Sun initiative (52%). The remainder would be supplied by utility scale solar, bioenergy, hydropower, imports and offshore wind. (See NYPSC: Minimal Cost to Meet 50% Renewable Goal.)

New York currently has about 2.5 GW of renewables: almost 2,000 MW of wind resources and 500 MW of solar.

Gavin Donohue, president of the Independent Power Producers of New York, said the REC-only approach is what brought the state to its current level of success. “It takes the risk away from ratepayers and puts it solely on … the generator sector,” he said. “We feel very strongly that if it’s not broke, don’t fix it.”

Donahue said long-term fixed contracts wouldn’t permit consumers to benefit from innovations that might lower power prices.

“The PPAs don’t reflect the changes over the long term in the marketplace,” he said.

Anne Reynolds, executive director of the Alliance for Clean Energy New York, said developers who belong to her group say the current REC model has limitations.

“Yes, the REC-only approach has gotten us a good deal of renewables built, but if you look at the pace of what we’ve accomplished over the past 10 years, it is not enough to get us to 50%,” she said.

“We think the way to do that is to attract the maximum number of developers we can to New York so that you get a robust lineup of projects and you get good competition.”

Consumers would benefit from long-term low prices and generation that doesn’t rely on fossil fuels, she said.

Tomorrow’s Grid is Here — Almost

By Rich Heidorn Jr.

WASHINGTON — A standing-room-only crowd got a glimpse of the grid of the future — and what’s keeping us from getting there — at last week’s Energy Bar Association Annual Meeting.

The session was titled “Tomorrow’s Grid is Here.” But in their description of the technical, regulatory and behavioral obstacles, some members of the panel seemed to want to add the word “almost.”

“Electricity is a public good. Yet the system we’ve got is going through a huge transformation and from my perspective there’s no one at the helm,” said Malcolm Woolf, former head of the Maryland Energy Administration who is now senior vice president with Advanced Energy Economy, a national business association.

“Utilities are doing exactly what they’re supposed to do based on historic incentives, but those may not be right for what we want today. The federal government is largely deferring to the states … and the states don’t really have the capacity to drive this. They don’t really know what they want.

“With the exception of a few states like New York and maybe California and Hawaii … I don’t think those conversations are going on.”

Not an Extension Cord

Woolf said policymakers need to stop thinking of the grid as “a long extension cord” with centralized generation and one-way power flow to a “market-maker network … where you’ve got a lot of distributed generation, a lot of centralized generation, all integrating to help our reliability and resiliency.”

Corporate America has moved more quickly than regulators, Woolf said. “Sixty percent of the Fortune 500 have renewable and climate goals, yet it’s only a handful that are going to be able to do deals because in most of the country it’s really hard to do deals. In North Carolina, the SolarCity — solar leasing — model is not legal. In Maine [and] still vertically integrated states, you can’t do offsite [power purchase agreements]. Talk to eBay who passed an offsite PPA bill three or four years ago in Utah and still hasn’t been able to get the project up and running.

The “MGM [Grand hotel and casino] in Vegas has just decided to go off grid and pay a massive $80 million penalty to NV Energy because they just want to self-generate,” he continued. “There’s a whole array of state barriers because no one thought that business wanted their own solution.”

Among the speakers was Deputy U.S. Assistant Energy Secretary Michael Pesin, who described the “three-legged stool” of research and development: technology, policy and markets. Rudolph G. Terry, director of the Philadelphia Industrial Development Corp., gave a presentation on the conversion of the Philadelphia Navy Yard from a defense installation to an urban industrial campus with its own microgrid.

Providing the utility perspective was Robert Stewart, manager of smart grid and technology for Pepco Holdings Inc.

Pepco has 26,000 net metering customers (360 MW of solar capacity) and is receiving 1,000 applications a month. It can’t accept them in some rural areas of New Jersey served by 12-kV lines. “We have five feeders that were closed [to new solar],” he said, adding that technical fixes will allow at least some to reopen eventually.

Impact of Electric Vehicles

Stewart © RTO Insider - future grid energy bar association conference

Stewart also talked about the potential impact of electric vehicles, and how to make them practical for low-income drivers who could benefit from their low maintenance and operating costs.

“The problem is most of these people live in multi-dwelling units. They can’t have their own charger. So rather than try and solve the issue with multi-dwelling units, if you gave them access to a charge someplace else — workplace charging through DC direct fast charge, [or] they stop and get a cup of coffee [and] top it off — it’s more like an appliance to them.”

Pepco faces another challenge in older, wealthier suburbs with high concentrations of EVs, such as Maryland’s Montgomery and Prince George’s counties. Because EVs draw about half the power of a full home load, such areas are at risk of overloading their transformers, Stewart said.

Based on a pilot program, Pepco believes most EV drivers will plug in between 4 and 8 p.m., increasing the afternoon peak load.

The company hopes to spread the load through time-of-use rates, which Stewart said could save the owner of a Nissan Leaf $300 a year. But utilities have a hard time making their case, he said.

“Even though you sit there with the numbers and you try to prove to them all you have to do is not charge between noon and 8 p.m. and you get [savings], the customer still is not with you,” he said. “They think there’s something behind the scenes. It’s too good to be true and the utility is really just trying to rip them off.”

PJM Market Implementation Committee Briefs

VALLEY FORGE, Pa. — The PJM Market Implementation Committee will hold a special meeting June 29 to continue discussion about the process for approving fuel cost policies and redefining terms, including “market seller.”

The changes, which stem from an annual review of Manual 15, were on the MIC’s agenda for endorsement Wednesday, but after spending one and a half hours talking about them, members asked to continue to work the issue.

One of the topics of discussion was new language added to clarify that the “market seller is the entity that submits a cost-based offer and is responsible for maintaining all information necessary to calculate resource’s cost-based offer.”

Members said they wanted to make sure that any new definitions were consistent with the Tariff.

Catherine Mooney of Monitoring Analytics also proposed language changes on behalf of the Independent Market Monitor.

“The purpose of Manual 15 is to develop the primary input for market power mitigation. This is one of the Market Monitor’s primary responsibilities,” she said.

In a case where a market seller is an agent of the generation owner, it needs to have access to all of the information required to not only calculate but also support a cost-based offer, she said.

Mooney also introduced language that would clarify the Monitor’s authority in evaluating fuel cost policies.

More Flexible Parameter Limited Exception Process Approved

The committee, with two abstentions, endorsed a proposal to make the parameter limited schedule exception process more flexible.

“The most important goal is to solve the problem of inflexibility,” PJM’s Tong Zhao said. (See “Manual Changes to Detail Unit-Specific Operating Parameter Adjustment Process under CP,” PJM Operating Committee Briefs.)

The revisions allow generators to request an exception if they learn of a need after the Feb. 28 deadline. They also permit a temporary exception to be extended to a period or a persistent exception if the need arises after the deadline.

In addition, the changes give PJM and the Monitor more time to review requests and give their determinations to market sellers.

Retroactive Black Start Billing Charges Focus of Proposed Study

PJM’s Tom Hauske introduced a problem statement and issue charge designed to mitigate the potential for large, retroactive black start charges.

Currently, the Tariff does not address when the Monitor will review the costs for new units entering black start service outside of the annual revenue recalculation period.

A number of new units have recently entered black start service, many replacing retiring units. To ensure PJM had sufficient resources, most of these new units entered service before their initial capital costs and annual revenue requirements were approved by the Monitor — some with a lag of six months or longer.

pjm market implementation committee

That resulted in significant charges to load in April.

“We would all benefit from more transparency. … If you have these things under review for a period of time and they’re accumulating charges, we’d like to see how large that accumulation might be,” said Jeff Whitehead of Direct Energy. “If we could minimize it, that would be good. If we can’t, we need to at least understand what the liability is going to be.”

“The back charges were a shock to our members and clients,” added Carl Johnson of the PJM Public Power Coalition. “Even if we don’t know what the scope of that is going to be, just knowing it exists is helpful.”

“There are more coming,” Hauske replied. “We can come up with an estimate.”

Conference Call Set to Discuss Auction-Specific Bilateral Transactions

A special MIC conference call will be held June 24 to discuss proposed clarifications to auction-specific bilateral transactions.

Assistant General Counsel Jen Tribulski said the changes aim to preserve the physicality of the transactions and ensure members’ indemnification.

The new rules assign auction credits and bonus payments to the buyer, while the seller retains the obligation to perform. (See “PJM Proposes Clarifications to Bilateral Transactions,” PJM Market Implementation Committee Briefs.)

Members said they wanted more information on the clarifications.

Committee Endorses Two Problem Statements from Members

With little discussion, the committee unanimously approved:

SPP Seams Steering Committee Briefs

SPP and MISO have ended months of uncertainty by agreeing to a second joint system study, which will take a “targeted” look at the two entities’ newly created Integrated System seam in the Upper Midwest.

SPP's Seams with MISO (ACES) SPP staff told the Seams Steering Committee, which met in Dallas on June 8, that the MISO members of the Interregional Planning Stakeholder Advisory Committee (IPSAC) voted last month to pursue the study. The Joint Planning Committee, composed of SPP’s David Kelley, director of interregional relations, and MISO’s Eric Thoms, manager of planning coordination and strategy, made it official May 31 when the two agreed to begin the study.

The RTOs conducted their first joint study last year, identifying three potential interregional transmission projects. However, they were unable to reach agreement on pursuing any of them. (See SPP, MISO Conclude Joint Study Empty-Handed.)

SPP’s interregional coordinator, Adam Bell, said both staffs have begun discussions on the study’s scope. He said the staffs are planning to discuss the draft scope at a possible IPSAC meeting in July and hopes to wrap up the study in the first quarter of 2017.

Kelley told the committee both staffs have a “desire” to do a larger study, but they are constrained by lack of manpower.

Bell said SPP will continue discussions with MISO to incorporate process improvements identified by stakeholders during the IPSAC’s March meeting.

SPP also is conducting a joint study with Associated Electric Cooperative Inc. (See SPP, AECI Endorse Scope for 2016 Joint Planning Study.)

Staff told the committee the study is focused on five “target areas” in AECI’s footprint where there have been recurring operational problems:

  • Northeast Oklahoma (potential overloads, voltage issues);
  • Southwest Missouri (potential overloads, voltage issues);
  • Central Missouri (potential low-voltage issues);
  • Wheaton area, southwest Missouri (potential upgrades); and
  • Mid-Missouri (potential low voltages).

“The scope was intentionally left broad to give us the flexibility we need to create these … areas and most efficiently target them,” Bell said. “Some stem from operational issues we see regularly that aren’t showing up in typical planning areas.”

The models are to be developed by the end of July, with preliminary results due in November and a final report in January.

Committee Recommends SPP Intervene in FERC’s NIPSCO Docket

The SSC unanimously endorsed a motion recommending SPP intervene at FERC in an ongoing dispute between MISO and PJM over their interregional planning (EL 13-88).

MISO and PJM have until June 20 to submit a compliance filing responding to an April 21 order in which the commission partially denied and granted a 2013 complaint by Northern Indiana Public Service Co. over the RTOs’ processes. (See MISO, PJM Working to Comply with NIPSCO Order.)

SPP’s options are limited because it did not intervene before the order was issued. Given choices between intervening out-of-time, commenting on MISO’s eventual compliance order or petitioning for a declaratory order, the committee voted to recommend the RTO “intervene out-of-time without comments but justification.”

“It’s really hard to come in at this late stage and ask for standing in the case,” Kelley said. He suggested SPP could intervene once MISO and PJM make their filing and potential Tariff changes.

The vote was partially driven by SPP member ITC Holdings’ intervention in the case. ITC, one of seven intervenors to request a rehearing of the order, said the commission should clarify that its directives to MISO also apply to potential interregional economic projects along the SPP-MISO seam.

FERC directed MISO to lower its interregional project voltage threshold with PJM from 345 kV to 100 kV and remove the $5 million minimum cost requirement. MISO currently has the same 345-kV threshold for economic projects along its seam with SPP, which has limited the ability of the entities to agree on interregional projects.

Staff reminded members that FERC is under no obligation to accept ITC’s request or clarify the applicability issue.

“My analysis leads me to believe … the commissioners probably won’t answer ITC,” SPP attorney Matthew Harward said. “If it grants ITC’s request for clarification, that could potentially impact SPP.”

Harward said he understood that several motions opposing ITC’s request have been filed, but he had yet to review them.

Kelley said MISO staff has told him the RTO is “taking the policy position that these things do not apply” to SPP and MISO and that the order is related only to the MISO-PJM seam.

Harward seemed to agree. “The order is narrowly drawn for the PJM-MISO seam,” he said.

DCNS Joins Maine Floating Turbine Consortium

French defense contractor DCNS Group has formed a partnership with Maine Aqua Ventus, the University of Maine-led consortium developing a floating offshore wind farm.

Maine Aqua Ventus aims to build a 12-MW wind farm near Monhegan Island in a pilot program supported by the U.S. Department of Energy. The role of DCNS, which builds submarines and naval vessels, is still being defined, according to the consortium.

Frederic Le Lidec, DCNS’s marine renewable energy director, said the company is working on three marine renewable technologies: tidal energy, ocean thermal energy conversion and offshore wind. He said DCNS is offering its services in engineering, construction, installation, maintenance and project management.

Shell Chemical to Build Pa. Ethane Cracker Plant

Shell Chemical Appalachia announced plans to build a massive, multibillion-dollar ethane cracker plant near Pittsburgh.

The plant will need 105,000 barrels of ethane a day, produced in the Marcellus and Utica shale fields of Pennsylvania, Ohio and West Virginia. It will break down, or “crack,” that ethane into 1.5 million metric tons of ethylene, a chemical used in the production of plastic, a year.

The complex will receive $1.65 billion in tax credits spread over a quarter century. Pennsylvania officials hope the complex will spur other industries in the area. Shell will begin construction within 18 months on the grounds of a former zinc smelter in Beaver County. While the company wouldn’t give an exact cost of the project, a similar ethane cracker in Lake Charles, La., cost $11 billion.

DTE Energy to Retire 8 Coal Units at 3 Plants

DTE Energy will close eight coal-fired units at three Michigan plants in the next seven years.

The Detroit utility said the affected units at its River Rouge, St. Clair and Trenton plants will be retired between 2020 and 2023. The three plants represent a quarter of the company’s total electricity production. The utility said employees impacted by the shutdowns will be offered jobs at its other facilities.

The move will leave DTE with just six coal-fired units of the 17 it had in 2015. Earlier this year, DTE retired three other coal-fired units and said the lost generation would be replaced with wind, solar and natural gas resources.

Dominion’s Chesapeake Center Coal Ash Estimate Triples

Dominion Virginia Power has three times as much coal ash stored at the company’s Chesapeake Energy Center near Norfolk than it previously estimated, according to documents received as part of a Sierra Club suit.

Dominion previously estimated the amount of coal ash at the site was about 1 million tons. But the company’s newer estimates say the three impoundments contain about 3 million tons.

The Sierra Club is asking in a civil suit for the company to remove all of the ash from the site to a lined landfill away from the Elizabeth River to prevent heavy metals from leaching into groundwater and into the river. The suit is scheduled to be heard later this month.

Toyota’s New HQ will Draw 25% Power from Solar

Toyota’s massive new North American headquarters in Plano, Texas, will draw about 25% of its electricity from a 7.73-MW solar facility mounted on three parking garages.

In the project’s first phase, two 2.45-MW systems will be installed by August 2017, with a 2.83-MW system by December 2017. The seven-building campus, which is about halfway finished, is expected to be completed sometime in 2017.

Toyota did not disclose the cost of the facility, one of the largest in the state. The company estimates the entire campus and moving costs for employees will total about $1 billion.

Talen to Run Natural Gas to Montour Plant

Talen Energy is in the process of selecting an entity to construct, own and operate a 15-mile pipeline to bring natural gas to the 1,500-MW Montour plant as part of a project to convert its two coal-fired units to dual-fuel by 2018.

The estimated cost of modifying the plant in north-central Pennsylvania, near the Marcellus Shale natural gas fields, is about $70 million.

“The Montour plant is located in close proximity to one of the largest natural gas formations in the world, the Marcellus shale,” Talen CEO Paul Farr said. “Co-firing the plant to burn natural gas produced in Pennsylvania enables Talen Energy to leverage the strategic location of the plant.”

Cities to Break Contracts with Indiana Michigan Power

Nearly a dozen cities in Indiana and Michigan have given Indiana Michigan Power the required four-year notice to end their power purchase agreements. The cities, which all belong to the Indiana Michigan Municipal Distributors Association, plan to break their contracts in 2020, six years earlier than the agreements were originally slated to end.

A city administrator in Niles, Mich., estimated that the city is paying 30% more than market price for electricity, while a general manager for Mishawaka Utilities, in Indiana, put the figure at around 20% over market value.

While the cities could individually buy electricity from other utilities, they can also renegotiate a deal with Indiana Michigan Power.

Public Utility Commission of Texas Briefs

AUSTIN, Texas — The Public Utility Commission of Texas approved a plan for a hybrid above/below-ground transmission line in the City of Frisco (Docket No. 44060). The project was notable for the financial commitment the city offered to bury the majority of the line. (See Texas PUC OKs Undergrounding Tx Line; City Agrees to Foot Cost.)

While the all-underground route would have cost more than $34 million — nearly $29 million more than the all-overhead route the PUC preliminarily approved — the city has agreed to pay approximately $13 million of the extra cost to have the lines buried in conjunction with an upcoming road-widening and waterline-installation project.

The cost savings of coordinating the projects was factored into the city’s calculations, along with other implications, such as where the project will be sited. The city contended that Brazos Electric Cooperative, the utility overseeing the project, would have had to pay for the right of way, but said it would donate it if the line was sited underground. This, along with some design modifications, brought the cost difference to approximately $4.3 million.

Briefs for ‘Precedential’ Decision

Commissioners called for parties involved in a substation-siting dispute to provide briefs on whether the PUC has jurisdiction in the case (Docket No. 45175). The Colony, a city near Dallas, is arguing that it has jurisdiction under the state’s Public Utility Regulatory Act to determine where the station can go. The local electric co-ops — Brazos and Denton County Electric — believe the PUC has authority under a different section of the same law.

Chairman Donna L. Nelson said the call for briefs in what she called a potentially “precedential” case was very wide to “get to the real heart of the conflict.”

Commissioner Kenneth W. Anderson Jr. said the commissioners gain much more insight from back-and-forth replies to other briefs, where the parties tend to “savage” each other.

‘More Meat’ Needed for New Interconnection Rule

The commission also adopted a rule to comply with several statutes that affect the paperwork necessary to tie into ERCOT’s grid (Project No. 45124). However, Anderson requested that, following the final approval, PUC staff open a new rulemaking process “to clarify the gaps that the statute doesn’t cover.” He said commission rules should delineate, among other things from the statute, what ERCOT should study to meet its need and reliability criteria, the impact on ERCOT’s market and the process to receive approval for a DC tie into the system.

All of these could have unforeseen consequences. For example, commenters pointed out that ERCOT’s handling of DC ties could — if too broadly defined — affect ERCOT’s independence from FERC jurisdiction.

“We need to put a little more meat on the bones of this rule because it’s not like the normal transmission asset,” he said.

‘Deceptive’ Offers on Customer-Choice Website

Saying that she continues to be “bothered” by “deceptive” offers on the website customers use to choose a power generator, Nelson announced a stakeholder meeting in her office June 21 to address the issue (Project No. 45730).

“Sometimes, I think things move a little faster when a commissioner gets involved,” she said. “The Power to Choose website kind of needs some work right now. The whole concept of choice doesn’t work if customers aren’t educated about what they’re buying.”

Anderson said he’s still “convinced” of the necessity of the website and that the only questions are exactly what might change. He said he uses it to shop and has always paid less than the last regulated rate.

The commissioners cautioned retail energy providers against putting out offers that are significantly below cost or whose rate requires meeting unreasonably specific consumption targets. However, they also disapproved of requiring retail electric providers to create standardized offers, saying those would be anti-competitive.

Though the site isn’t perfect, Commissioner Brandy Marty Marquez urged consumers who are overwhelmed by the shopping process to request a tutorial from PUC staff, who find it “one of the most exciting things” to do, she said.

‘Shock’ over SPP Z2 Billing Plans

Marquez said it was “shocking” that SPP plans to request repayment over 10 months of transmission upgrades that were approved over a period of more than eight years. (See related story, Z2 Project Faces Further Hurdles, Possible Delay.)

The commissioners said they were concerned for ratepayers shouldering the burden of the repayments over such a short period.

Additional Actions

The commission also:

  • Approved applications by American Electric Power’s Texas affiliates, Texas New Mexico Power, Oncor, CenterPoint Energy and Sharyland Utilities to adjust their energy-efficiency cost-recovery factors.
  • Returned to an administrative law judge the application by Luminant and Oncor to transfer ownership and administration of the decommissioning trust for Comanche Peak Nuclear Power Plant. The application was based on a plan that is being changed and resubmitted by the bankruptcy court overseeing the decommissioning process, so it needed to be revised.
  • Approved publishing a proposed rule on how distributed generation facilities can connect to the grid (Project No. 45078). The proposal would allow interconnection agreements to include the end-use customer, the owner of the DG facility, an owner of rights to energy produced from the DG facility or the owner of the premises at which the DG facility is located.

Federal Briefs

The Supreme Court on Monday declined to review a D.C. Circuit Court of Appeals ruling allowing EPA to continue enforcing its Mercury and Air Toxics Standards (MATS) while the agency complies with a 2015 high court ruling to address procedural issues (15-1152, Michigan, et al. V. EPA, et al.).

In the 2015 decision, the court found that EPA had failed to take costs into consideration when deciding whether the MATS rule was “appropriate and necessary” under the Clean Air Act. The court allowed EPA to continue enforcing the rule, however, while the agency addressed the court’s concerns. The agency responded with a supplemental finding, saying the cost review did not change its opinion on the need for the rule and proposing to leave MATS unchanged.

Several states asked the D.C. Circuit to require the agency to conduct a new rulemaking, a request the court rejected in December. The litigation is largely moot: Most power plants covered by the rule complied or retired by the deadline of April 2015. Some plants received a one-year extension on the deadline, which has also passed.

IEA Says Renewable Subsidies Still Needed

A report by the International Energy Agency says that subsidies are still needed to ensure continued growth of renewable energy.

iea(iea)Government subsidies make renewable energy projects less risky investments. But the IEA warns that as the energy generated by renewables becomes less expensive, governments may look to scale back the subsidies.

“As we enter this new phase, the question becomes what can the policymaker do to maintain bankability [and] reduce the risk of investments in generation without just throwing subsidies out, which isn’t where anyone wants to be,” said Toby Couture, director at the German renewable energy consultancy E3 Analytics and an author of IEA’s report.

Iceland Testing New Carbon Capture Method

carbfix(carbfix)Scientists working in Iceland are testing a new method of carbon capture and sequestration, injecting CO2 from a geothermal plant into basalt to form calcite, theoretically locking the gas in the ground permanently.

CarbFix, as the project is known, has so far resulted in about 95% of the CO2 injected being converted to calcite. So much calcite was formed by the testing process that a pump used to test the water became clogged with the mineral. The scientists found that the calcite formed in less than two years.

Iceland is practically all basalt, making it an ideal location to test the new method. The project is being conducted in partnership with the Icelandic capital’s municipal utility, Reykjavik Energy, at a plant about 15 miles east of the city. Work is being done now to figure out a way to scale the project up to industrial sizes and to find other suitable locations with enough basalt.

Report: US Solar Installations To Double in Coming Year

gtmresearch(gtm)Developers rushing to meet a deadline for a federal solar tax credit are driving U.S. solar installations to nearly double the total capacity in 2016, according to a report by GTM Research. By the end of the year, 14.5 GW of solar capacity will be online, the report says.

Solar installations rose 24% in the first quarter this year, about 64% of all new electric generation capacity during that period, according to the report.

Most of the utility-scale projects were pushed through on expectation of the year-end solar tax credit expiration. The credit was extended for five more years, however. The extension will spur more than 20 GW of additional solar capacity by 2021, GTM said, though the utility-scale market is expected to contract next year and in 2018.

FERC Grants Rehearing On NJ Pipeline Project

transco(transco)FERC has granted the request for new hearings on Transco’s Garden State Expansion project after a group of municipalities said the company failed to give proper notice of meetings and didn’t meet environmental requirements.

Although not a large project — it involves a new compressor station, upgrades to another substation and upgrading some existing pipeline — the municipalities and environmentalists called it a win.

“Anytime we get FERC to reopen a docket and have a rehearing is an environmental victory,” said Jeff Tittel, New Jersey Sierra Club director. “FERC almost never grants a rehearing and the fact that they did it shows that there were significant problems in the approval of Transco’s application.”

Annual NRC Meeting on Indian Point Gets Heated

indianpoint(nrc)The Nuclear Regulatory Commission held its annual public meeting on the operation of Entergy’s Indian Point nuclear station, and things got heated, with members of the public telling the commission it is failing in its job to keep the plant operating safely.

“You don’t care about our lives, you don’t care about our future,” said Susan Shapiro, who identified herself as a member of the Indian Point Safe Energy Coalition, a protest group. “All you care about is how you are going to grease the pockets of Entergy.”

David Lew, an NRC deputy administrator overseeing the northeast region, said Indian Point is operating within guidelines. “Our overall conclusion is that Indian Point operates safely and will continue to operate safely,” he said.

Talen Reports Leaks At Susquehanna Plant

talensusquehanna(talen)Talen Energy, operator of the Susquehanna nuclear plant in Pennsylvania, reported the discovery of two small leaks of radioactive water while shutting Unit 1 down last week for regular maintenance.

Staff discovered one leak inside the containment structure and a second leak in lines leading to instrumentation sections of the unit. Both leaks were contained and there was no danger, according to the report made to the Nuclear Regulatory Commission.

“When the plant is operating, there are certain areas you can’t access when it’s in power,” said spokesman Todd L. Martin. “When we did the downpower to address the initial leak, that’s when we found this additional leakage, and that prompted the second notification.”
