Hitachi contributed to this sustainable and unique project by providing domain expertise and delivering a state-of-the-art grid connection to supply power to Fortum’s excess heat recycling plant.

The solution’s compact footprint was based on advanced gas-insulated switchgear, delivering excellent efficiency and availability, while minimizing the total life cycle cost and its CO2 footprint.

Overview

– Hitachi supplied the grid connection for a project in Finland that will recover and recycle excess heat from data centers to heat Fortum´s various customer premises, such as homes and public and business premises.

Outcomes

– The excess heat recycling project will be the largest in the world, dedicated to transferring heat from data centers to a district heating system. Its goal is to bolster Finland’s growth and competitiveness by advancing sustainable decarbonization, while increasing digitalization.

– The servers in the data centers are powered by renewable energy and recovering and recycling this excess heat into district heating paves the way towards the target of carbon- neutrality by 2030.
