Vihreä Watti Oy and Helen Oy have entered into a strategic partnership aimed at enhancing grid flexibility and enabling new revenue streams for customers through smart battery solutions and demand response services.
The collaboration focuses particularly on the needs of corporate and institutional clients, combining Vihreä Watti’s delivery capabilities with Helen’s electricity market expertise. In this partnership, Vihreä Watti will supply innovative and scalable battery solutions to customers, while Helen provides smart flexibility services and electricity contracts that enable participation in reserve markets (FCR-D, FCR-N, aFRR, mFRR) and Nord Pool wholesale markets (Spot and Intraday) using batteries delivered by Vihreä Watti.
For large-scale battery projects, Vihreä Watti is the exclusive official partner in Finland of BYD—a global leader in battery manufacturing—and Enershare. BYD's technology is recognized worldwide for its reliability, safety, and efficiency. This partnership brings high-performance energy storage solutions to the Finnish industrial and commercial sectors.
The high price volatility in the Finnish electricity market has created a growing demand for new solutions that help manage energy price risks and improve grid balance. Smart batteries offer a way to both store energy and actively participate in the electricity markets—for example, by selling stored electricity back to the grid when prices are high.
“This partnership with Helen allows our customers to maximize the value of their battery investments,” says Lauri Pääkkö, COO of Vihreä Watti Oy. “We deliver advanced battery systems that not only provide backup power or protection from outages but also generate real financial returns through active market participation.”
At the heart of the collaboration is a simplified customer experience. The services are designed for easy adoption: the battery systems are directly integrated with the demand response service, meaning customers don’t need to manage complex market operations themselves—AI-based systems handle optimization automatically on their behalf.
Antti Martikainen, Chief Growth Officer at Helen, sees the partnership as supporting the company’s strategic goals:
“We aim to promote smart electricity usage and help our customers lower their energy costs. With Helen’s services, the profitability of the batteries delivered by Vihreä Watti improves significantly.”
