As battery owners and operators seek to maximise the returns from their assets, they simultaneously face the Herculean challenge of managing degradation.

Following February’s excellent Energy Storage Summit at London’s Victoria Park Plaza hotel and hosted by our publisher Solar Media, here’s a short series of videos posing some of the big questions around energy storage, renewables, climate change, business and the industry, and more.

Hornsdale Power Reserve (HPR), the 129MWh battery energy storage system (BESS) deployed by Tesla and developer Neoen in South Australia in just 100 days, has been found to have had a positive impact on the local network.

Battery assets have been used in the UK’s Balancing Mechanism for the first time via a virtual power plant, marking the start of what could be a new era for energy storage business models in Britain.

Energy asset developer and owner Statera Energy has clinched a refinancing deal for its 50MW Pelham utility-scale battery storage plant in England, in a transaction which it says demonstrates both the maturity and “bankability” of the asset class.

Eelpower, a UK-based developer which has executed renewables and cleantech projects including hydroelectric-plus-storage, has secured a £20 million (US$28.5 million) investment from investment trust Gravis Capital Management to build out its pipeline of permitted energy storage sites and pursue new development opportunities.

News in brief from around the world of energy storage.

UK demand response and energy resource aggregation company Kiwi Power has unveiled its largest behind the meter battery to date with the completion of the 4MW / 4.8MWh Tesla battery at Cenin Renewables in south Wales.

National Grid has revealed a simplified, more standardised approach to Firm Frequency Response (FFR) procurement whilst teasing the first details of its fast-response follow-up to EFR.

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.
