Expected ROI of utility scale ESS project in Finland 2025

Is energy storage a viable solution for the Finnish energy system?

This development forebodes a significant transition in the Finnish energy system, requiring new flexibility mechanisms to cope with this large share of generation from variable renewable energy sources. Energy storage is one solution that can provide this flexibility and is therefore expected to grow.

Are high Vres shares possible in the Finnish energy system?

In conclusion, these studies indicate that high VRES shares in the Finnish energy system are possible, but require measures such as energy storage and demand response for their successful integration. 3.

Which energy system will be the most cost-efficient in Finland in 2050?

A study showed that even a 100 % RES-based energy system will be the most cost-efficient in Finland in 2050, albeit this requires many actions, such as better interaction between electricity, heating and mobility sectors.

What factors influence the development of energy storage activities in Finland?

Several parameters are influencing the development of energy storage activities in Finland, including increased VRES production capacities, prospects to import/export electricity, investment aid, legislation, the electricity and reserve markets and geographic circumstances.

What is the electricity supply in Finland in 2022?

The electricity supply in Finland is quite diverse. As presented in Fig. 1, the Finnish electricity supply in 2022 consisted of nuclear power (29.7 %, 24.2 TWh), different types of thermal power plants (24 %, 19.6 TWh), imports (15.3 %, 12.5 TWh), hydropower (16.3 %, 13.3 TWh), wind power (14.2 %, 11.6 TWh), and solar power (0.5 %, 0.4 TWh).

How does the Finnish TSO respond to the growing number of renewable installations?

The Finnish TSO, Fingrid, is continuously taking measures to respond to the fast-growing number of renewable installations. The power system is getting more complicated both from a technical and commercial perspective, with many large changes occurring simultaneously both in electricity production and consumption.
