An accusation has been made that Hornsdale Power Reserve, the landmark large-scale battery energy storage system (BESS) in South Australia, did not deliver ancillary services as offered over a four-month period in 2019.
India’s biggest grid-scale battery storage system to date received a visit from Delhi government minister Satyendar Jain, who emphasised the urgent need for energy storage to stabilise the grid and incorporate higher shares of renewable energy sources.
Wärtsilä will deploy a 5.2MW / 5.2MWh energy storage system (ESS) to help support Taiwan’s grid, joining the frequency regulation market launched this year by state-owned utility Taiwan Power Company (Taipower).
Updated 27 July 2021: An RWE spokesperson told Energy-Storage.news that the combined capacity of the BESS installations will be 128MWh across the two sites. It was also confirmed that the project will be commercially-oriented, rather than a demonstration of the technology or potential business models.
