The US National Renewable Energy Laboratory (NREL) has put numbers on the significant potential for energy storage to replace peaking capacity on the grid in the US, albeit with an understanding that as the peak changes, the goalposts will also move. NREL has said in a report just-published that around 70GW of peaking capacity in the US – from a total base of about 261GW – could be served by energy storage systems of four, six and then eight hour durations.
Providing peaking capacity could be a significant U.S. market for energy storage. Of particular focus are batteries with 4-hour duration due to rules in several regions along with these batteries’ potential to achieve life-cycle cost parity with combustion turbines compared to longer-duration batteries.
Plummeting solar-plus-storage costs could help electrify millions worldwide by facilitating a ten-fold explosion of mini-grid systems, a new report from the World Bank has said. Its report said most new mini-grids will feature a mix of PV with batteries, adding that the 10-15GW of solar / 50-110GWh of mostly lithium-ion batteries expected by 2030 would bring CO2 savings of 1.5 billion tonnes.
Highview Power has announced a modular cryogenic energy storage system, the CRYOBattery, that is scalable up to multiple gigawatts of energy storage. The systems can enable renewable energy baseload power at large scale, while also supporting electricity and distribution systems and providing energy security. The system uses liquid air as the storage medium and provides all the services essential for a robust grid including time shifting, synchronous voltage support, frequency regulation and reserves, synchronous inertia, and black start capabilities.
The U.S. Energy Storage Association congratulates NV Energy on its recent plan to deploy nearly 600 MW of energy storage by 2023. This exciting announcement builds upon a nationwide trend in energy storage market growth. We especially applaud NV Energy for partnering with third parties in this effort, sending a strong signal for businesses to invest in energy storage in Nevada.
San Diego International Airport in California will be home to a battery energy storage system paired with onsite solar PV that is set to reduce electricity costs as well as deliver much-needed reductions in carbon emissions and peak demand charges. Comprising as much as 40% of the airport’s monthly energy bills, the energy storage system will help reduce these demand charges.
A “second-life” energy storage system using ex-EV batteries developed by Professor Jae Wan Park and his graduate students at the UC Davis Green Technology Laboratory. Made possible by a grant from the California Energy Commission, this project is reducing the on-peak energy use and carbon footprint of the UC Davis Robert Mondavi Institute — a combined winery, brewery, and food processing complex.
Energy storage technology is changing the industry as it truly becomes a shock absorber in the struggle to balance supply and demand as solar and wind generation increases. This integrated technology is moving the electric power delivery industry closer to the fabled virtual power plant, which is why energy storage has been called the enabling technology. The technology of plus storage is rapidly becoming a force to be reckoned with and only the surface has been scratched.
NV Energy is making major plays in response to Nevada’s recently-raised RPS, as the company announced today that it will be purchasing power from three massive projects, totaling 1.2 GW of solar and 590 MW of battery storage.
The Hawaiian Electric Industries, the parent company of Hawaii’s investor-owned utilities, has officially kicked off the second phase of its renewable energy procurement agreement, whose roots date back to 2017. Of the Hawaiian Islands, phase 2 procurement focuses on Oahu, Maui and Hawaii, with the former two given clear renewable generation and battery storage targets.
