The Åland FLEXe-demo project is one of the largest island trials in the world to switch to 100 percent renewable energy. It is supported by the Finnish government and involves a number of leading companies including Pöyry. The project comprises six clusters, of which Pöyry has been selected for the Energy Storage Cluster. This will see the company managing the development of the storage system for the project, with two main aims. The first of these is to achieve short-term grid stabilisation and the second is the delivery of long-term seasonal storage capacity to get the island through the winter on renewable power sources.
The challenge is to integrate the storage system into the wider design that will comprise a high content of variable renewables, which includes wind and solar PV, biomass and also the transition to e-mobility of public and private transport, all connected through a smart grid.
“Optimising energy storage of different timescales and especially seasonal storage to compensate summer-winter variation in Finland is extremely demanding” said Tommy Jacobson, CEO of CLIC Innovation and Leader of the Åland FLEXe-demo project. “It is also the critical subsystem to ensure the stability, security and economical viability of the fully renewable energy system to be designed for the Åland Islands. To achieve this Pöyry complements FLEXe-ecosystem with latest know-how in energy storage systems”.
Michael Gruenenfelder, Regional Director Europe & New Markets for Thermal Power and Renewable Energy at Pöyry, added that the project puts Pöyry at the forefront of developments in the new energy world.
