Battery storage

Hybrid power plants, also known as solar plus storage or wind plus storage projects, have gained significant traction in recent years. These projects combine solar energy or wind energy with battery energy storage. The result is a somewhat dispatchable renewable energy power plant, which can provide smoother (less-volatile) energy, and can shift time of delivery […]

SAN FRANCISCO (June 16, 2020) — Sunrun Inc. (Nasdaq:RUN), the nation’s leading home solar, battery storage and energy services company, and Southern California Edison (SCE), the largest utility in Southern California and one of the largest in the country, today announced they are working together to launch one of the first residential energy storage virtual […]

Alabama Power’s Smart Neighborhood integrates a microgrid into a community filled with high-performance homes containing energy-efficient systems and connected appliances. The innovative initiative, which

SAN FRANCISCO (May 19, 2020) — Pacific Gas and Electric Company (PG&E) has requested approval of five energy storage projects totaling 423 megawatts (MW), in a filing with the California Public Utilities Commission (CPUC). The projects are intended to further integrate clean energy from renewable generation sources while ensuring future reliability of the electric system. […]

The Energy Information Administration (EIA) in February 2020 published capital costs and performance characteristic estimates for 25 new electric power generating technologies. These estimates come from global engineering and design firm Sargent & Lundy (S&L), which the EIA commissioned to help accurately reflect the changing cost of new power generation technologies for the Annual Energy […]

Much has been written about renewable energy, but few stories have focused on the complexity of determining the optimal mix of solar and wind generation, and the kind and amount of energy storage, that

Onshore wind and photovoltaic (PV) solar power are the cheapest forms of new-build power generation for at least two-thirds of the world’s population, according to analysis published by research company BloombergNEF (BNEF). Meanwhile, battery storage has become the lowest-cost new-build technology for peaking purposes in gas-importing regions, such as Europe, China, and Japan. BNEF reported […]

The U.S. Bureau of Land Management said it continues to work on issuing a permit for a $1 billion solar power project in Nevada, after already missing two deadlines to move the project forward. The proposed 690-MW Gemini solar farm in Nevada is one of the country’s largest proposed solar projects. It would be operated […]

Lithium-ion battery technology promises the first realistic approach to fully integrating intermittent solar and wind into the U.S. power system. Despite its recent growth and great potential, the battery

A new conveyor-based system offers an alternative energy storage technology. The heart of the system is a reversible conveyor belt that converts between electrical energy and gravitational potential energy by
