Saft, a wholly-owned subsidiary of Total, has won an order for three Intensium Max 20 High Energy containers from TuuliWatti, the Finnish wind developer and operator. The lithium-ion (Li-ion) energy storage system (ESS) will support frequency regulation at a 21 MW wind farm in north-western Finland. It will also optimise wind power, as well as provide backup and black start capabilities.
The Li-ion ESS is sized to provide an energy storage capacity of 6.6 MWh and deliver 5.6 MW of power for frequency regulation throughout its 15-year lifetime. It comes in three integrated containers of 2.2 MWh each, designed and manufactured at Saft's site in Bordeaux, France.
Saft launched the Intensium Max 20 HE to address the majority of grid, renewables, commercial and industrial applications that require large-scale ESS solutions with discharge times of around two hours.
