As storage plays an increasingly central role in the energy transition, so too is the importance of managing battery degradation. Giriraj Rathore of battery storage system integrator Wärtsilä Energy Storage & Optimisation explores some of the main strategies for successful battery augmentation, a key means of offsetting the impacts of system degradation.

BloombergNEF has launched its Energy Storage Tier 1 list of providers, noting growth in new players from the China market.

Wärtsilä’s decision to launch a strategic review of its energy storage & optimisation (ES&O) business, including potential divestment, may be because of its dilutive effect on the broader company’s margins, an analyst told Energy-Storage.news.

The renewable energy IPP arm of UK utility SSE is to start building a 320MW/640MWh battery energy storage system (BESS), which could be the largest under-construction in the country.

Power technology firm Wärtsilä has initiated a strategic review of its energy storage and optimisation (ES&O) business, with “all potential alternatives considered” including divestment.

Substantial growth in China’s domestic energy storage market has led to locally-based players Sungrow and Hyperstrong becoming top five system integrators globally, S&P Global Commodity Insights said.

System integrator Wärtsilä has signed an MSA with Eve Energy while peer Powin is targeting 5GWh of US-made BESS equipment in its supply chain by 2025.

Independent power producer (IPP) Clearway Energy has closed US$421 million in financing for the 147MW/588MWh four-hour Rosamund Central Battery Energy Storage System (BESS) in Kern County, California.

Wärtsilä has revealed details of fire testing its large-scale battery storage product was put through, which the company claimed went beyond commonly accepted requirements.

Work is set to begin “within weeks” on a BESS project at the site of a coal power plant in New South Wales, Australia.
