Finland BESS outdoor power supply

Which energy storage system will support the Finnish power grid?

This 38-megawatt and over 40-megawatt-hour energy storage system will support the Finnish power grid. The project is slated for completion by spring 2025 and will be located in Lappeenranta, near the Mertaniemi power plant.

Is this Finland's largest battery energy storage system?

Swedish flexible assets developer and optimizer Ingrid Capacity has joined hands with SEB Nordic Energy’s portfolio company Locus Energy to develop what is claimed to be Finland’s largest and one of the Nordics’ largest battery energy storage systems (BESS). The 70 MW/140 MWh BESS project will be located in Nivala, northern Finland.

What makes Finland's power system stable?

Finland’s power system stability has traditionally been supplied by conventional power plants and hydropower. However, the transformation in the power generation mix creates a greater need for other sources of flexibility. BESS are excellent alternatives because of their capability to charge and discharge energy.

How does Bess work in Finland?

BESS operators can also participate in cross-border markets to provide storage capacity for ancillary services, such as frequency regulation, which helps maintain grid stability and reliability. Ancillary services are currently the primary revenue source for BESS in Finland.

Why does Finland need Bess?

The need for BESS is exceptionally high in Finland because the country has set one of the world’s most aggressive climate targets. The government has a legal obligation to reach carbon neutrality by 2035. Renewable energy sources account for over 50% of electricity production, and several renewable projects are being planned or developed.

How long is a Bess project in Finland?

New BESS projects in Finland are generally moving to 2-hour durations, including the largest under-construction at 112.9MWh, by IPP Neoen, which optimiser Capalo AI explained in our coverage of that project last week. Essentially, new state-of-charge rules and increasing opportunities in energy trading have driven the business case beyond 1-hour.
