(IN BRIEF) Nefco has signed a EUR 5 million loan agreement with Merus Power to support the Finnish company’s international expansion in electrical energy storage and power quality systems. As Europe increases its reliance on renewable energy, demand for storage and stabilisation technologies continues to rise, making Merus Power’s solutions essential for improving grid reliability and energy efficiency. The company already operates in more than 70 countries and has contributed significantly to renewable energy integration. This investment is also Nefco’s first EIF-backed loan, following a new agreement aimed at improving financing access for Nordic green SMEs. Leaders from both organisations highlighted the importance of the partnership in advancing clean energy technologies and supporting Europe’s transition to a more sustainable power mix.

(PRESS RELEASE) HELSINKI, 20-Nov-2025 — /EuropaWire/ — Nefco, the Nordic Green Bank, has strengthened its support for clean energy solutions by providing a EUR 5 million loan to Merus Power Plc, a Finnish company recognised for its advanced electrical energy storage systems and power quality technologies. The investment will help Merus Power accelerate its international expansion, particularly in Northern and Central Europe, where demand for grid-stabilising and storage solutions continues to grow alongside the rise of renewable energy.

According to CEO Kari Tuomala, the new financing marks a significant boost for the company’s global ambitions. He noted that Nefco’s support enables Merus Power to scale its innovations more rapidly and reach new customer segments in key European markets. The company’s technologies play an essential role in ensuring energy security and enabling a transition to cleaner power systems.

As the share of renewables in the EU’s overall energy mix is planned to increase from 23% in 2022 to at least 42.5% by 2030, the need for effective storage and power quality solutions is rising sharply. Without such systems, integrating large amounts of intermittent wind and solar energy can lead to grid instability and blackout risks. Merus Power’s solutions are designed to address these challenges by improving grid flexibility, smoothing out power fluctuations, and enhancing overall energy efficiency.

Since its founding in 2008, Merus Power has delivered its power quality technologies to industrial, utility, infrastructure, and renewable energy customers in more than 70 countries. In 2020, it expanded into electrical energy storage systems in Finland, and by the end of 2024, its solutions had helped connect 630 MW of renewable energy to electric grids while contributing to the mitigation of approximately 240,000 tons of CO₂.

Earlier this year, Nefco established an agreement with the European Investment Fund (EIF) to increase access to financing for Nordic green SMEs. The Merus Power loan is Nefco’s first investment partly backed by the EIF, marking an important milestone for the financing initiative. Helena Lähteenmäki, Investment Director at Nefco, emphasized that the arrangement helps bridge existing financing gaps and supports the scaling of proven Nordic clean-tech solutions. She noted that Merus Power is well positioned to continue expanding internationally, supported by the strengthened financial framework.
