Energy storage

We live in a world of “slow growth and volatility,” said Jeffrey Immelt, chairman and CEO of General Electric, but there’s an opportunity to “make a lot of money” if you have courage in such times.

  Look out Tesla, the Germans are coming. The U.S. residential energy storage market took another step forward on January 29 when German firm sonnen announced that it was partnering with solar manufacturer SolarWorld to offer residential solar-plus-storage systems in the U.S., much like the systems announced by Tesla and Solar City last April. Unlike […]

The Department of Energy (DOE) announced on January 15 that it was awarding up to $40 million each in cost-shared funding to Southern Co. and X-Energy to “support work to address key technical challenges to the design, construction, and operation of next generation nuclear reactors.” It also announced on January 18 that it was awarding […]

In mid-November, current members of POWER’ s Generating Company Advisory Team responded by email to a set of questions about their concerns, challenges, and new initiatives as they plan for the year ahead

Battery storage firms and energy storage experts at the Energy Storage North America (ESNA) conference in San Diego Oct. 13–15 were effusive in their praise of battery storage’s potential while

Duke Energy announced the completion of a 2-MW battery-based energy storage system that has been installed to increase power grid reliability and stability for the PJM regional transmission organization. Installed at its retired W.C. Beckjord coal-fired power plant in New Richmond, Ohio, construction began in August, and the system was placed in operation on Nov. […]

The German battery storage market took a leap forward as German generating company Steag announced on Nov. 4 that it will invest €100 million in six 15-MW battery storage projects at several of its power plants in Germany. The batteries are expected to come online mid-2016 through early 2017. The facilities will be sited at Steag’s generating […]

Energy storage needs better energy storage policy. Speaking at the Energy Storage North America (ESNA) conference in San Diego on Oct. 12, Garrett Fitzgerald, senior associate with the Rocky Mountain Institute (RMI), was frank about the challenge facing energy storage technologies: They’re starting to get well ahead of the regulatory regimes that are needed to […]

Battery energy storage has exploded in deployment over the past several years, but the majority of it by capacity, especially in North America, is deployed at grid scale. That may be a problem, because a new study from the Rocky Mountain Institute (RMI) suggests the greatest value to the system lies with behind-the-meter batteries—distributing battery […]

AES has begun construction of what will be the largest energy storage project in Europe when it comes online later this year in Carrickfergus, Northern Ireland. The 10-MW/40-MWh Kilroot Advancion Energy Storage Array is being added to the AES UK & Ireland Kilroot Power Station in County Antrim along the country’s east coast. The grid-connected […]

Emerging energy technologies such as rooftop solar, microgrids, and distributed generation could adversely affect reliability of the nation’s grid, a new report from the Electric Markets Research Foundation (EMRF) warns.  The non-profit research entity whose mission it is to fund studies on significant electric market issues notes in its report, “Changing Uses of the Electric […]

Concentrating solar power has found a partner in thermal storage, but costs remain high. Solar photovoltaic generation may have a partner in rapidly expanding battery options, but the economics are uncertain. Is there room for both approaches, or will one be crowded out? Battery storage is officially hip. Once a subject of concern largely only […]

What turns a trend from trendy to established? In the energy industry it can be any number of things, from a technology breakthrough, to a new market, to forces of nature. The shale gas boom in the U.S. is the most well-known example of a technology trend that has changed the economics for all power […]

“When pigs fly” is a figure of speech used to express disbelief that a particular situation will ever come to pass. For the power industry, several recent and emerging developments are the equivalent of

The Solana Generating Station ( solana in Spanish means “sunny spot”) is built on a 1,920-acre site near Gila Bend, about an hour’s drive west of Phoenix. According to Abengoa, which owns the facility

Just as POWER predicted in its May issue (see “The Year Energy Storage Hit Its Stride”), energy storage is starting to gain traction, not only in the U.S., but around the globe. Europe’s largest commercial battery power plant was connected to the German grid in mid-September. With a power rating of 5 MW and an […]

Regulators in California last week initiated rulemaking to push the state’s three investor-owned utilities to incorporate distributed energy resources (DERs) into the planning and operation of their electric distribution systems. The California Public Utilities Commission’s (CPUC’s) Aug. 14 Order Instituting Rulemaking establishes rules, policies, and procedures to guide Pacific Gas and Electric, Southern California Edison, […]

Developers of renewable energy projects in Puerto Rico must incorporate energy storage into new installations under recently approved standards. The Puerto Rico Electric Power Authority and the island territory’s government-owned utility, Autoridad de Energía Eléctrica (AEE) on Dec. 12 released a new minimum technical requirementthat requires new grid-connected solar and wind power projects to add […]

The U.S. must first develop unsubsidized, cost-effective energy storage technologies, validate reliability and safety, establish an “equitable” regulatory environment, and boost industry acceptance before it will see the widespread deployment of energy storage systems, says a report released today by the Department of Energy (DOE) to members of the U.S. Senate.  Commissioned by Sen. Ron […]

A final rule issued by the Federal Energy Regulatory Commission (FERC) on Nov. 22 allowing energy storage projects to connect with the electric grid could boost the energy storage industry’s presence as a backup power source for intermittent energy sources, industry experts say. FERC Order No. 792 amends Order No. 2006—the pro forma Small Generator […]

The California Public Utilities Commission (CPUC) today unanimously established an energy storage target of 1,325 MW that California’s largest investor-owned utilities, Pacific Gas and Electric Company, Southern California Edison, and San Diego Gas & Electric, must meet by 2020. The decision will help California optimize the grid with measure such as peak reduction, contribute to […]
