Saft to build the largest lithium-ion energy storage system in the Nordics

France-headed battery manufacturer Saft Groupe SA a wholly-owned subsidiary of global oil, gas, and energy major Total S.A, has won an order for three Intensium Max 20 High Energy containers from TuuliWatti Oy, the Finnish wind developer, and operator. The Lithium-Ion energy storage system (Li-ion ESS) will support frequency regulation at a 21 MWe wind farm in northwestern Finland. It will also optimize wind power, as well as provide backup and black start capabilities.

French battery manufacturer Saft Groupe, a wholly-owned subsidiary of Total has won an order for three Intensium Max 20 High Energy containers from Finnish wind power developer and operator TuuliWatti. The Lithium-Ion energy storage system (Li-Ion ESS) is the largest in the Nordic countries and 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 (image courtesy Saft).

The Lithium-Ion energy storage system (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. 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, said Tommi Riski, Portfolio Manager for Power at TuuliWatti.

Founded a century ago, Saft specializes in advanced technology battery solutions for industry, from design and development to production, customization and service provision.

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.

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, said Hervé Amossé, Executive Vice-President ESS division at Saft.
