A subsidiary of Enel is jointly developing a large-scale lithium-ion battery system project with wind power developer ENERTRAG, in what will be the multinational utility’s first energy storage project in Germany.

The Indian Budget has seen a hike in customs duty for lithium-ion batteries from 10% to 20%.

Energy storage in the state of South Australia has continued its prolific pace of development with the announcement of two new grid-scale projects and a sizeable commercial and industrial (C&I) installation.

Younicos will carry out another project to retrofit lithium-ion batteries in replacement for an existing lead acid battery system at a wind farm, this time in Hawaii.

VLC Energy has become the latest firm to finish its Enhanced Frequency Response (EFR) battery projects following the completion of two projects totalling 50MW.

Adding energy storage gives solar developers and the industry in general the ability to “keep going”, while offering both lithium and flow battery systems covers a “wide-range of use cases”, NEXTracker CEO Dan Shugar has said.

German-American system integrator and technology provider Younicos has completed a two-phase operation to upgrade a lead acid energy storage system for lithium batteries, at the 36MW Notrees facility in Texas.

Primus Power is among a handful of makers currently commercialising their flow batteries, with rivals that include RedT, VIZn Energy and Redflow. Early customers have included Microsoft, which installed a Primus battery at its corporate HQ in a pilot project. Andy Colthorpe spoke with Primus Power CEO Tom Stepien to learn more.

Changes to the de-rating factors for battery storage projects competing in the UK’s Capacity Market (CM) will push the sector towards longer-duration batteries, while potentially sparking a shift towards energy arbitrage as a source of revenue for shorter duration applications. David Pratt heard from several industry sources following last week’s announcement.

A sustainable energy company founded by Swindon Borough Council, a local authority in western England, has submitted plans for a 50MW battery energy storage system (BESS) for its latest project.
