Quality control problems affect a sizable number of new energy storage systems, creating potential safety and performance risks, a new report indicates.

A recent study found that deploying 37 GW of long-duration energy storage could help bring California to zero emissions by 2045.

ERCOT stakeholders are moving closer to taking action on a tabled rule change that would address the reliability concerns with inverter-based resources.

While the deployment of utility-scale battery storage has accelerated in recent years, additional regulatory and policy support is needed to scale up the industry, a panel of experts convened by CESA said.

ERCOT is focused on dispatchable resources to meet the ever-increasing demand for energy in Texas.

Texas regulators have delayed approval of a protocol change that would set a controversial state of charge for batteries that one commissioner said is “totally discriminatory.”

Battery storage that charges from the grid should be able to use non-firm transmission service, MISO has decided.

Form Energy hopes to use its long-duration iron-air batteries to firm up renewable energy generation across extended stretches in New England.

ISO-NE can consider transmission-only battery storage as an option to address transmission system issues, FERC ruled.
