Total subsidiary Saft has secured an order from TuuliWatti to deliver a lithium-ion energy storage system for the 21MW Viinamaki wind farm in north-west Finland.
The deal covers three Intensium Max 20 high energy containers totalling 6.6 megawatt-hours to provide frequency regulation throughout the project’s 15- year lifetime, as well as backup and black start capabilities.
Total said the 2.2 MWh each containers were designed and manufactured at Saft’s plant in Bordeaux, France.
TuuliWatti portfolio manager for power Tommi Riski said: “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 Viinamaki by improving the competitiveness of wind power.
“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.”
Saft executive vice-president of the energy storage division Herve Amosse said: “This contract is an early commercial success for Saft’s latest lithium-ion energy storage system, launched in May 2019.
“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.
“It builds on Saft’s track record of success with high-power energy storage systems.”
Saft launched the Intensium Max 20 HE to address the majority of grid, renewables, commercial and industrial applications that require large-scale storage solutions with discharge times of around two hours.
