Merus Power receives a 20-million-euro order to supply a large battery energy storage system to Taaleri Energia

Taaleri Energia has ordered a 30 MW/36 MWh battery energy storage system from Merus Power. The battery energy storage is to be built in Lempäälä, Finland to support the operation of the electric grid.

Merus Power is the project developer and is responsible for the overall delivery of the energy storage starting from obtaining the building permit. The contract also includes Merus Power’s cloud service which includes remote energy storage management and an electricity trading platform that optimizes battery usage and the customer’s income from the electricity market.

The main task of the battery energy storage system in Lempäälä is to support the balancing of production and consumption in the main grid by participating in the frequency reserve market of Finland’s Transmission System Operator called Fingrid. The energy storage will capacity-wise be Finland’s largest energy storage operating in the frequency reserve market.

“We have been systematically building expertise in understanding the electricity market and solving customer needs for years. This agreement with Taaleri Energia is strong proof of the functionality of our energy storage strategy and our position at the top of this value chain,” says Kari Tuomala, CEO of Merus Power.

Renewable energy investments help overcome the energy crisis

Taaleri Energia is a Finnish renewable energy project developer and fund manager with one of Europe’s largest renewable energy investment teams. It is also Finland’s largest producer of wind power.

“Renewable energy is the only sustainable way out from the current energy crisis and to achieve global climate targets. Storage facilities are needed in order to further increase the share of renewable energy in the electricity grid. With this project, we are creating stability and balance in the electricity network and returns for our investors,” says Ville Rimali, Energy Storage Investment Director at Taaleri Energia.

Electricity production and consumption must be in constant balance. The increasing production of renewable energy has significantly changed the nature of the electricity grid and the electricity market as well as the need for balancing. This is due to wind and solar power being connected to the grid without a large rotating mass, unlike traditional condensing power plants. The inertia of the electric grid decreases and changes in production and consumption cause faster and larger frequency changes. To compensate for this, an electricity reserve that can be quickly activated and deactivated is needed. The battery energy storage system in Lempäälä will be able to react to the need to balance the electricity grid even in fractions of a millisecond.

A modern energy storage is a complex and demanding system consisting of batteries, power electronics, and intelligent software. The grid inverters, control and protection systems, and the electricity trading platform of the Lempäälä energy storage system are all designed and programmed by Merus Power. Merus Power has unique technological expertise and competence, thanks to which it can act as a provider of the entire business value chain. The electricity trading platform developed by Merus Power combines a deep understanding of battery energy storage systems with the knowledge of the latest earning opportunities in the electricity market.

“The software is optimized for our products and suits our customers’ needs. In addition, we are close by and can quickly make changes that consider tomorrow’s requirements and needs, even in existing systems. This ensures high availability in both short and long term,” says Merus Power’s Project Development and Financing Director, Mikko Marttala.
