CEO’s greetings

“The energy market is undergoing an unprecedented transformation, as a result of which renewable energy sources are playing an increasingly important role in total energy production. The efforts behind this are to curb climate change and reduce industrial greenhouse gas emissions. Technological developments are helping to accelerate this transformation by reducing the deployment costs of renewable energy and decentralizing energy production to different parts of the electricity system. The energy transition poses significant challenges to power system management. Energy must be able to be managed, regulated, and stored efficiently in order to ensure a constant balance between supply and demand.

Merus Power is a Finnish technology company operating in the global market, focusing on innovative and scalable energy storage systems and power quality solutions. With our world-class technical competence, we are contributing to the global shift towards sustainable energy and enabling the use of renewable energy sources in growing markets. Our ever-growing staff has a passion for technology and represents internationally valued expertise.

We have been actively developing our business and product portfolio throughout our more than ten-year history and have successfully delivered solutions to over 70 countries around the world. We are proud of the important work we do to support green transition, enable the growth of renewable energy in electricity networks, and help our industrial customers operate more energy efficiently achieving their own goals.

We aspire to be a major smart grid solution manufacturer in the Nordics and recognized as a preferred supplier in the global battery energy storage and power quality markets. With our growth strategy, we aim for strong growth in the energy storage market and the integration of renewable energy. In addition, we aim to grow faster than the global market for power quality solutions. Global megatrends support the growth in demand for renewable energy and provide us with a strong growth platform.”

History of Merus Power


The dawn of Merus Power

Merus Power was founded in 2008 to meet the challenges of industrial power quality and connecting wind power to the electrical grid. The founders of our company are 4 brilliant Finnish engineers; Kari Tuomala, Jyri Öörni, Aki Leinonen, and Risto Laakso, who all share a common background working together prior to Merus Power.

At first Merus Power’s business growth was sought from industrial power quality solutions as the relative share of renewable energy in the electrical grid was rather small. Our operations focused on power electronics, advanced software technologies, and electrical engineering expertise, as well as their application to energy savings and productivity improvements in industry and real estate.
