Energy Storage: Ready for its Close-Up?

On Laurel Mountain, W.V., AES Corp. installed 32 MW of battery storage to support its 98 MW wind farm. The project provides PJM with regulation service and allows AES to smooth minute-to-minute fluctuations in output from its turbines.

In Hazle Township, Pa., Beacon Power is installing 200 flywheels that will provide PJM 20 MW of frequency response. The company put 4 MW into commercial operation on September 11 and expects the full 20 MW plant operational next year.

In Lyon Station, Pa., batteries housed in what look like large storage sheds are providing 3 MW of frequency regulation to PJM and peak demand management services to Met-Ed.

These are the vanguard of energy storage applications that will change both the economics and operations of the grid — providing quicker, more accurate frequency regulation, aiding in the integration of variable resources, eliminating the need for some grid upgrades, and providing alternatives to natural gas-fired peakers.

PJM members will be asked Thursday to approve an initiative to draft market rules to allow batteries, flywheels and other advanced energy storage devices to participate in the RTO’s capacity market.

This raises the question: Is advanced storage ready to move beyond pilot projects and into day-today operations?

Pumped hydro, a decades-old technology, currently provides virtually all of the grid’s storage capability, with more than 127,000 MW installed worldwide. Compressed air energy storage installations are second, followed by sodium-sulfur batteries. Other technologies total less than 85 MW combined.

Experts say some of the most promising storage applications, such as hydrogen-powered fuel cells that could provide bulk storage, are a decade or more from commercial deployment. But some more mature technologies could take significant roles in the next several years.

“The future is already here — at least the beginning of the future,” said Imre Gyuk, manager of the Department of Energy’s energy storage research program, at a briefing earlier this month in Washington.

Costs

For storage to reach its potential, its costs must come down at the same time that its capability improves.

Storage can provide benefits in regulation, voltage support and power quality and reliability as well as deferring transmission and distribution upgrades and reducing the need for peaking generators. But “even with all those benefits, it’s difficult to make it add up” to exceed costs, Haresh Kamath, energy storage program manager for the Electric Power Research Institute (EPRI), told the briefing.

Most energy storage technologies have higher capital costs than natural gas-fired peakers. Flywheel capital costs are similar to a combined-cycle plants. Sodium sulfur (NaS) batteries, the most economical battery for utility-scale applications, have been estimated at 1.8 to 3.5 times the cost of a combined cycle plant.

The two crucial of measures of storage capability are cycle life (the number of complete charge-discharge cycles before becoming unusable) and round-trip efficiency (the system’s energy output relative to input). Improving these measures will boost storage in comparisons against generation.

Market Rules

In addition to the cost and technology challenges, market rules are also an obstacle to widespread deployment.

Storage can provide several benefits simultaneously to the wholesale system, electric distribution companies, and end-use customers. “These characteristics, plus the difficulty in monetizing multiple stakeholder benefits, often act as barriers to the widespread deployment of energy storage systems, whose multi-functional characteristics also complicate rules for ownership and operation among various stakeholders,” EPRI said in a 2010 white paper. It concluded policy changes would be needed “to realize the true potential of storage assets.”

Rule Changes Could Quadruple Revenues

Researchers at Energy and Environmental Economics reported in a 2009 paper that storage revenues could be increased by as much as four-fold by reducing minimum size requirements for market participation and permitting bi-directional bidding for regulation.

The study looked at potential revenues for a theoretical storage resource located in Allentown, Pa., based on 2007 market clearing prices ($41/MW-day for capacity, $14/MWh for regulation and $34/MWh for energy). It found a system with 1 MW of charge and 2 MWh of energy storage would generate revenues of more than $250,000, most of it from regulation, with additional revenue from capacity and energy arbitrage — storing energy overnight when prices are low and selling during peak hours.

As of the time of the study, PJM capacity rules required a minimum of 12 hours of capacity and a minimum resource size of 0.1 MW.

One key to increasing revenues, the analysis found, was permitting asymmetric bidding in the regulation market — allowing the battery to earn regulation revenue when charging and discharging — in recognition that regulation dispatches over an hour can be energy neutral.

Changing market rules to permit asymmetric bidding and to allow energy storage to offer one hour of regulation with less than one hour of energy storage would increase the net present value of energy storage in PJM from about $1,000 per kWh of energy storage to nearly $3,500.

FERC Order, Stimulus Funding

Storage received a boost from the Federal Energy Regulatory Commission in July with Order 755, which requires PJM and other transmission providers to consider speed and accuracy in acquiring regulation resources. (See FERC Rule Boosts Storage, Renewables.)

Storage also was a prime beneficiary of federal stimulus money under the 2009 American Recovery and Reinvestment Act (ARRA). About $185 million in ARRA funds leveraged $585 million from industry for 16 energy storage projects, not including eight smart grid projects with storage. The goal of the federal spending is to demonstrate the technologies’ technical feasibility, document costs, stimulate regulatory changes and generate follow-on projects. Four of the 16 projects have been completed to date.

Proposed Legislation

To provide additional incentives, Sen. Ron Wyden (D-OR), chairman of Senate Energy and Natural Resources Committee, and Sen. Susan Collins (R-ME) reintroduced legislation in May to create an investment tax credit for energy storage.

California Storage Mandate

With or without federal incentives, a lot more storage will be added over the next few years. On Sept. 3, the California Public Utilities Commission issued a proposed order requiring the California grid to obtain 1.3 GW of storage by 2020, a target that will require utilities to increase their storage by 30% annually.

The order was prompted by Assembly Bill 2514, which barred pump storage projects larger than 50 MW from eligibility in order to enable a “market transformation” for new technologies.

The order would prohibit utilities from owning more than 50% of the storage resources to be procured across the three “grid domains” of transmission, distribution, and customer-located storage.

To address utilities’ concerns that the 2020 goal is too ambitious, it would allow utilities to defer up to 80% of their targets if they can show they can’t procure enough “viable projects to meet the targets.”

EPRI’s Kamath said California’s mandate could do for storage what Germany’s world-leading commitment to solar power did to reduce solar’s “soft” costs, including permitting, inspection, interconnection, financing and customer acquisition.

“It’s going to have effects all across the industry,” said Klamath.

Binz Nomination in Doubt with Manchin Defection

Ron Binz’ nomination to the FERC chairmanship was hanging by a thread late last week after coal-state lawmakers took the former Colorado regulator to task at his confirmation hearing and Sen. Joe Manchin (D., W.V.) announced he would oppose the nominee.

Binz testifies
Binz testifies

Binz will need the backing of one Republican and all of the remaining 11 Democrats to win the recommendation of the 22-member Senate Energy and Natural Resources Committee. That will be tough for Democrats to pull off.

Ranking member Lisa Murkowski (R-Alaska) has already stated her opposition and no Republicans spoke in favor of Binz at his confirmation hearing Tuesday. Also in doubt is Sen. Mary Landrieu (D., La.), who has not indicated she will support the nominee.

`War on Coal’ Target

If Binz’ nomination fails, it will be because he became the target for those angry over the Obama administration’s so-called “war on coal.”

Binz would have limited influence over coal’s life or death as FERC chairman: Although FERC policies ensuring transmission access for renewables impacts coal indirectly, the agency has no role in the setting of climate or pollution policy.

But the timing of his confirmation hearing was inauspicious. The War-on-Coal blowback reached a crescendo last week as the EPA issued its long-awaited greenhouse gas limits on new power plants.

Manchin complained at Tuesday’s hearing that Obama’s environmental policies were beating the “living crap” out of his state. On Wednesday, he announced his opposition to Binz, criticizing him for prioritizing “renewables over reliability.

“His approach of demonizing coal and gas has increased electricity costs for consumers,” Manchin said.

Colorado PUC

Binz served as chairman of the Colorado Public Utilities Commission from 2007 through 2011, during which he drew praise from renewable energy advocates and opposition from the coal industry.

Binz participated in the drafting of Colorado’s Clean Air-Clean Jobs Act, which offered utilities incentives for replacing coal-fired power plants with natural gas. The bill, which was opposed by the coal industry, led to the retirement of six coal-fired generators, the addition of pollution controls at two others and the construction of new gas generation at a cost of about $1 billion. See: Who is Ron Binz, And What Will He Do at FERC?

Binz told last week’s hearing he would be “source neutral” and emphasize reliability as FERC chair. He noted that coal provides 40% of Colorado’s electricity, more than any other source. He also acknowledged he had spoken “inartfully” at a forum when he called natural gas a “dead end” fuel.

Norris Allegation

Adding to Binz’ woes last week were comments from FERC Commissioner John Norris, who reported that Senate Majority Leader Harry Reid persuaded President Obama to reject him as FERC chairman because he was too “pro-coal.”

Norris, a Democrat, told TransmissionHub that Reid’s chief of staff cited a vote he made as a member of the Iowa Utilities Board. Reid’s office denied Norris’ account.

Senate Minority Leader Mitch McConnell (R-Ky.) said Thursday that he would actively work against the nomination of what he called the Senate Majority Leader’s “foot soldier in his and this Administration’s War on Coal.”

Companies Unplug from Grid, Jolting Utilities

The number of electric generation units at commercial and industrial sites has more than quadrupled since 2006, leading utilities such as AEP to consider getting into the on-site power business.

On-site generation still accounts for less than 5% of U.S. electricity production. But it is gaining momentum because of falling prices for solar panels and natural gas, as well as a fear that power outages caused by major storms will become more common. Wal-Mart, which produces about 4% of the electricity it uses, plans to boost that to 20% by 2020 and expects to be paying as little for solar power as utility power in less than three years.

Bowling Green Outlaws Fracking, Niles Repeals Ban Amid Labor Opposition

The Bowling Green City Council banned fracking and disposal of fracking waste fluids while Niles City Council unanimously repealed its own ban on oil and gas drilling.

Niles reversed the “Community Bill of Rights” it enacted in August in a meeting packed with anti-drilling advocates pleading to keep the ban and labor unions encouraging its repeal. Opponents of the ban said the law might not withstand a legal challenge because the state Department of Natural Resources claims only it can license drilling.

But Bowling Green’s attorney said his city’s ban is part of the city’s criminal code, not its zoning code. The city is an unlikely target for drilling because of a high water table and unsuitable geology.

FERC Rejects Settlements over ATSI, Duke Moves to PJM

WASHINGTON – The Federal Energy Regulatory Commission today rejected settlements by FirstEnergy and Duke Energy affiliates over their moves to PJM, ruling that the companies unfairly imposed transition costs on transmission customers who were not party to the agreements.

The orders involve FirstEnergy’s American Transmission Systems Inc. (ATSI), which moved from MISO to PJM in June 2011, and Duke Energy’s Ohio and Kentucky utilities, which moved to PJM in May 2010.

In both cases, the commission ruled that the settlements improperly reinstated transition costs that the commission previously ruled should be borne by the utilities, unfairly leaving non-settling parties liable.

The cases originated from the companies’ filings of revised transmission tariffs that reflected their revenue requirements as PJM members. American Municipal Power Inc. (AMP) challenged both Duke and ATSI’s rate filings.

Duke Settlement

In February 2013, Duke Energy Ohio and Duke Energy Kentucky filed a settlement agreeing to reimburse AMP for any transition costs resulting from Duke’s move to PJM. The companies also agreed to reimburse AMP for 75% of “legacy” transmission expansion costs — Duke’s share of MISO transmission projects approved before the company joined PJM. Duke estimated the transition costs and legacy costs at $518 million.

The settlement also reduced the return on equity included in Duke’s wholesale rates from 12.38% to 10.88% percent (plus 50 basis points for its membership in a regional transmission organization). AMP — which buys transmission from Duke on behalf of Hamilton and Lebanon, Ohio and Williamstown, Ky. — agreed not to seek a lower ROE before 2016.

In today’s order (docket # ER12-91), the commission ruled that Duke had “not shown why it is not unduly discriminatory for AMP, but not other customers, to be exempted from paying” the transition costs.

ATSI Settlement

ATSI’s rate filing sought recovery of $38 million in transition costs while agreeing to forgo recovery of $360 million in legacy transmission expansion charges.

The company’s settlement, filed in December 2012, exempted AMP and Buckeye Power Inc., from paying any costs of the utility’s move to PJM but left it to the Ohio Public Utility Commission to determine what costs would be passed on to retail customers served by other distribution companies.

Buckeye Power is a generation and transmission cooperative owned by 25 electric distribution cooperatives in Ohio.

“While other wholesale customers may not have objected to the [AMP, Buckeye] settlement, these customers are largely served by ATSI’s distribution affiliates,” the commission ruled (docket # ER11-2814). “Thus, the lack of objection from these affiliates … has no bearing on the justness and reasonableness” of the agreement.”

The ruling was a victory for the Ohio Consumers’ Counsel (OCC), the lone challenger to the ATSI settlement.

OCC contended that ATSI was seeking to use the settlement as an “end-run” to include in its transmission rates charges prohibited by FERC in a May 2011 order.

Next Steps

The commission said ATSI and Duke could attempt to recover their transition costs through section 205 filings. Those filings would have to demonstrate that the benefits received by the companies’ customers as a result of the move to PJM exceeded the transition costs assigned to them.

FERC also remanded the issue of Duke’s ROE for further hearing and settlement judge procedures. The commission said that although the reduced ROE provisions “appear just and reasonable,” it was unable to accept them because of a “non-severability” clause in the settlement.

Notification, Startup Rules to Take Effect Sept. 26

Generator start and notification rules will be implemented in eMKT beginning Sept. 26, PJM told the Market Implementation Committee last week.  The Operating Committee last week endorsed related changes to Manual 14D: Generator Operational Requirements.

Reason for change: The changes were approved in 2012, following a January 2011 problem statement by PJM and the Market Monitor that noted there were no rules governing unit start and notification times. This made scheduling more difficult for PJM staff, left units unavailable for lengthy periods and permitted the exercise of market power, officials said.

Impact:

  • During the Peak Period (Jan., Feb., June, July and Aug.) the notification plus startup time must not exceed six days. Units will be in forced outage status until they can operate within the six-day limit.
  • During Off Peak months (March, April, May, Sept., Oct., Nov. and Dec.) units may offer extended notification times that accurately reflect the physical time to bring the unit to the beginning of the startup sequence.
  • Manual 14D: Generator Operational Requirements was revised: Added applicability for individual generating units greater than 20 MVA; replaced outdated reference to NERC Guidelines with reference to NERC Reliability Standards; Added requirement for generators operating or scheduled to operate for PJM to notify PJM prior to attempting a restart following a trip or failure to start.

More information: Members can review a summary of the changes in the eMKT Enhancements section and test the changes in the “sandbox” environment prior to implementation.

Additional information can be found in the Issue Tracking section of PJM.com. PJM will answer questions through the PJM Markets Hotline and via phone at 610-666-8998.

The EPA’s proposed greenhouse gas limits on new power plants will not be as strict as initially proposed, but will still effectively prohibit the construction of new coal-fired plants, according to news reports.

Plants burning natural gas reportedly will be permitted to emit about 1,000 pounds of carbon dioxide per megawatt-hour, easily within reach of modern plants. Coal-fired plants would be limited to 1,400 pounds per MWh, requiring carbon capture, a technology not yet commercially viable. The American Public Power Association is asking the White House for a looser limit on coal plants, calling a standard requiring carbon capture “unrealistic.” The rules are expected to be released this week.

PJM’s recommended Installed Reserve Margin (IRM) will increase slightly because of the increasing alignment of the RTO’s peak demand with demand outside of the region, according to a preliminary analysis presented to the Planning Committee Thursday.

The analysis recommends an IRM of 16.2% for delivery year 2014/15 (up from 15.9% in the 2012 analysis) and margins of 15.7% for delivery years 2015 through 2017.

The IRM is increasing despite a small reduction in the average Effective Equivalent Demand Forced Outage Rate (EEFORd).

PJM’s Tom Falin told members the reason for the increased IRM was an increase in the “World Peak” — the world’s share of its annual peak coincident with the PJM annual peak — to 96.4% from 95.4% last year. “We’re seeing a little less help coming in from the other regions,” Falin explained.

The study results will re-set IRM for the 2014/15 through 2016/17 delivery years and establish the initial IRM for 2017/18.

The IRM must be finalized by February 1 prior to its use in next year’s capacity auction.
