    1. An Inside Look at Using Energy Storage to Integrate Renewable Resources

      An Inside Look at Using Energy Storage to Integrate Renewable Resources

      California is a leader in both renewable energy resources and energy storage. The state has one of the highest renewable portfolio standards in the U.S., mandating that 50% of all electric power be sourced from renewable resources by 2030, and the state has the first and some of the most robust incentives for energy storage. AB 2514 requires the state’s three investor owned utilities to procure 1.3 GW of energy storage by 2020, and AB 2868 requires each IOU to deploy an additional 166 MW of behind-the-meter and/or distribution tied storage.

    2. Utilities See Benefits in Energy Storage, Even Without Mandates

      Utilities See Benefits in Energy Storage, Even Without Mandates

      The fact that California’s three investor-owned utilities were at the top of the Smart Electric Power Alliance’s recent rankings is not surprising, but the presence of utilities in Indiana and Ohio is notable. California has been a leader in energy storage, with a 2010 law that requires the state’s IOUs to procure 1.3 GW of storage capacity by 2020 and then a 2016 law requiring each IOU to procure another 166 MW of storage.

    3. Choosing the Right Grid Infrastructure in the wake of the DOE Grid Study

      Choosing the Right Grid Infrastructure in the wake of the DOE Grid Study

      Since its release last week, the Department of Energy’s grid study has been under the harsh scrutiny of a broad range of industry players.The study was roundly criticized well in advance of its release by many stakeholders expecting it to unjustifiably blame renewable energy for the challenges facing the grid. Thankfully, the study that emerged last week has failed to live up to those fears. Instead, the report is generally fact-based and well-researched, and the key findings–that low natural gas prices and flagging load growth are primarily to blame for the economic crunch facing coal and nuclear power plants and that renewables pose no threat to our grid–are well-documented and well-understood by stakeholders ranging from the U.S. military to utility CEOs.

    4. Is the Bloom off the RegD Rose for Battery Storage in PJM?

      Is the Bloom off the RegD Rose for Battery Storage in PJM?

      The market for energy storage frequency regulation in the PJM Interconnection has had its ups and downs in the past year or two. After an initial boom that began to overwhelm PJM’s frequency regulation market, the RTO put the brakes on battery storage installations. PJM quickly followed up by changing the parameters of its frequency regulation signal and then proposed further changes in how it calibrates the relationship between fast response resources, such as batteries, and conventional resources, such as gas turbines. Those changes were met with howls of protest by energy storage developers, some of who are contesting the changes at the Federal Energy Regulatory Commission.

      CAISO: Alternatives to Puentes Gas Plant Could Cost Up to $1.1B

      By procuring distributed resources that include solar power, demand response and energy storage, the California ISO has determined that construction of a natural gas power plant proposed for Ventura County could be avoided. In June, CAISO announced it would study clean energy alternatives to a planned gas expansion near the city of Oxnard, Calif., which looked to replace the 573 MW Mandalay Bay natural gas facility operated by NRG.

      Platts: US has more than 550 MW of grid-connected energy storage in Q2

      Platts, reporting on storage data filed with FERC, concludes the United States had 565.5 MW of storage capacity installed at the end of the second quarter — with about a third of the capacity coming online in the last year. In total there are 45 grid-connected systems, the bulk of which are battery storage. Two projects are flywheel storage.

      Connexus Energy Planning Minnesota's Largest Energy Storage Facility

      Connexus Energy, Minnesota’s largest retail electric cooperative, is in negotiations to build a 20 MW, 40 MWh energy storage system, Midwest Energy News reports. The storage facility would be located next to three solar power plants with an aggregate capacity of 10 MW that Connexus plans to build next summer. Connexus says the energy storage system could be deployed for a combination of uses, including peak shaving, demand response, and frequency regulation.

      Energy Storage Association Outlines Ways for States to Promote the Technology

      The Energy Storage Association published a report with recommendations on cost effective state policies for energy storage. "State Policies to Fully Charge Advanced Energy Storage: The Menu of Options," says that current market structures and policies lack clear mechanisms to identify and capture the full value of energy storage systems. The report says states should focus on value, competition and access in order to achieve the maximum benefit from energy storage.

      Gas Plant Makers Embrace Batteries with Hybrid Machines

      New offerings from turbine manufacturers are blurring the line in the debate about whether or not an energy storage facility can replace gas-fired peaking plants. Earlier this month, Wartsila signed a memorandum of understanding with Southern Co. to develop two flexible gas-fired power projects. The MOU coincides with Wartsila’s acquisition of Greensmith Energy Management Systems. Wartsila said the acquisition would enable it to provide both stand-alone energy storage systems, as well as hybridized energy systems that combine conventional generators with energy storage.

      Third Time's the Charm: Regulators Accept HECO Plan for 100% Renewables

      The Hawaiian Public Utilities Commission has accepted a plan filed by the state's largest utility Hawaiian Electric Co. (HECO), outlining how it will reach 100% renewable energy resources by 2040 — five years ahead of the state's goal. HECO's latest iteration of its Power Supply Improvement Plan (PSIP) update was accepted by the PUC on July 14, and it outlines the work to be done by Hawaiian Electric, Maui Electric and Hawai‘i Electric Light. Along with acquiring almost 400 MW of renewable generating capacity, the plan includes adding energy storage and other grid technologies to aid resiliency, and assumes the continued growth of private rooftop solar.

      Maryland, Hawaii Turn to Storage Incentives as State Markets Gain Momentum

      Nevada earlier this month became the fourth state to adopt an energy storage incentive. The Silver State joins California, New Jersey and Maryland, which in April passed a bill creating a 30% tax credit for energy storage devices, as the only states to have put storage incentives in place. And at least two other states, Hawaii and Massachusetts, are moving toward energy storage incentives.

      How Can Tucson Electric Get Solar + Storage for 4.5¢/kWh?

      Tucson Electric Power’s recently signed power purchase agreement for a solar-plus-storage project has been hailed for its low price, but it also signals a solution that could become more common as renewable energy grid integration problems grow. TEP declined to reveal the exact pricing, but the all-in cost for the solar-plus-storage project is “significantly less than $0.045/kWh over 20 years,” said Carmine Tilghman, senior director for energy supply at TEP. And, at under 3¢s/kWh, he says he believes the solar portion of the PPA is “the lowest price recorded in the U.S.”

      Nevada Lawmakers Pass Bills for Storage Incentives, Possible Mandate

      Lawmakers in Nevada's House and Senate have approved a slate of clean energy bills that will now head to Gov. Brian Sandoval’s (R) desk, according to the Las Vegas Sun. The bills would establish incentives for the installation of energy storage associated with solar systems, direct the Public Utilities Commission of Nevada to consider energy storage mandates, and boost energy efficiency funding for low income residents.

      Brattle: Wider Electrification Key to Averting Both Climate Change and Utility Death Spiral

      The utility death spiral has been at the center of a debate about how well energy storage plays with solar power, but a new report from The Brattle Group questions death spiral premise and calls for utilities to play a larger role in combating climate change. In the death spiral scenario, renewable energy penetration – facilitated by the ability of energy storage to fill in the gaps of solar and wind generation – fosters a vicious circle of declining utility sales and rising electricity rates.
