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 northwestern Finland. It will also optimize the wind power, as well as provide backup and black start capabilities.
The Li-Ion ESS, the largest in the Nordic countries, 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.
“TuuliWatti’s goal is to be the leading wind power developer and producer in the Arctic region. Saft’s high-energy containers will help us achieve this at Viinamäki by improving the competitiveness of wind power,” says Tommi Riski, portfolio manager for power at TuuliWatti. “They provide a fast response in challenging environmental conditions, as well as the energy storage capacity to support grid stability, allowing us to adjust the output of our wind farm immediately.”
“This contract is an early commercial success for Saft’s latest lithium-ion energy storage system, launched in May 2019,” adds Hervé Amossé, executive vice president of the ESS division at Saft. “The Intensium Max 20 HE container offers more than twice the energy storage capacity of previous Saft containers and provides best-in-class energy density, lifetime and assured performance.”
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.
