A “first-in-the-nation” policy called the Clean Peak Standard has been launched in Massachusetts, US, whereby a proportion of electricity used on the grid at times of highest demand must be considered ‘clean’.

Stationary energy storage in support of electric vehicles (EVs) charging could reach a global installed capacity of 1,900MW by the end of 2029 according to a new Guidehouse Insights report.

The US Federal Energy Regulatory Commission (FERC) hosted a technical conference on hybrid resources – pairing storage with generation – examining in order to overcome barriers that exist to the otherwise fastest-growing phenomenon of the grid.

More up-to-date training could have prevented severe injuries sustained by four firefighters in the April 2019 fire and explosion at battery storage facility in Arizona, according to a report into the incident from UL Firefighter Safety Research Institute (UL FSRI).

There’s a race to develop new technologies – and adapt existing ones – that can either be complementary to lithium batteries, or even compete with them. Representatives from three technology providers offer up some case studies, data, insights and opinions on where they think the market could go.

Independent power producer EDF Renewables North America has signed a 22-year power purchase agreement with NV Energy for a 200MWac solar project coupled with a 180MW, four-hour battery storage system.

US developer and utility NextEra Energy has said there is currently a “terrific opportunity” for wind, solar and battery storage while Texas-based CPS Energy plans to add up to 900MW of solar, 50MW of battery storage and 500MW of new technology solutions to its portfolio.

California investor-owned utility (IOU) Pacific Gas & Electric has begun work constructing a 182.5MW / 730MWh battery energy storage system (BESS) project at a substation in California.

Long duration energy storage is “essential” to help accelerate renewable deployment, according to the US Department of Energy’s Dr Imre Gyuk, who moderates this panel discussion with Matt Harper from flow battery provider Invinity Energy Systems and Russ Weed from gravity energy storage company ARES.

An April 2019 fire and subsequent explosion which caused injuries to firefighters and destruction of a grid-scale battery storage system in Arizona likely started with an internal cell defect that caused the “preventable” incident, analysis has found.
