What Merus Power Dynamics does
Merus Power Oyj (commercial name Merus Power, formerly Merus Power Dynamics) is a Finnish clean-technology company founded in 2008-2009 and headquartered in Ylöjärvi, Finland. The company designs, manufactures, and sells modular battery energy storage systems (BESS) and power quality solutions built on proprietary in-house power electronics technology. Its product portfolio centers on two franchises: the Merus ESS energy storage system paired with the Merus PCS power conversion system for grid-scale battery storage, and a power quality lineup comprising the Merus A2 active harmonic filter, Merus HPQ hybrid power quality solution, Merus STATCOM static synchronous compensator, and Merus SVC static var compensator. The company has deployed 676 MW of capacity connected to the grid, claims a 22% share of the Finnish electricity market's usage reserve, and reports 333,000 tonnes of annual customer CO2 emission reductions.
The company sells primarily through direct enterprise sales to utilities, distribution system operators, transmission system operators, and renewable energy developers across Northern Europe, with named customers including Alpiq, Exilion, wpd, Latvenergo, and Savon Voima. Revenue is generated predominantly through hardware sales of BESS projects (typical sizes of 30-60 MW systems valued at €10-17 million each), supplemented by power quality equipment sales and lifecycle maintenance services. The company has demonstrated technical differentiation as the first to deploy a grid-forming BESS approved by Fingrid (Finland's TSO) in the Nordics, and as the first to deploy Arctic-capable grid-forming BESS in Rovaniemi, Lapland.
Merus Power listed on NASDAQ OMX First North Growth Market in June 2021 (ticker MERUS), raising approximately €12 million in an oversubscribed IPO. It subsequently secured a strategic partnership with CATL in June 2026 for approximately 3 GWh of BESS deployments across Northern Europe, alongside expansion into Latvia (Latvenergo contract, up to €15 million) and Romania (R.Power partnership). All manufacturing and R&D operations are based in Finland, and the company holds ISO 9001, ISO 14001, and ISO 45001 certifications, plus UL 508 listing for its active harmonic filter product family.
