Wood & Co Acquires 75MW of Ready‑to‑build Battery Storage Projects in Finland From BHM Group

Why It Matters

The deployments give Wood & Co a foothold in the fast‑growing Nordic storage market, where ancillary‑service revenues now dominate battery economics, and support its 15% return target. Success will signal the viability of large‑scale BESS as core grid infrastructure across Europe.

Key Takeaways

• Wood & Co acquires 75 MW/150 MWh BESS projects in Finland
• Centrica Energy to optimise 70 MW/160 MWh Swedish BESS for Ånge
• Finnish projects target Q2 2027 commissioning; Swedish project Q2 2026
• Nordic ancillary‑service markets now dominate BESS revenue, especially mFRR
• Wood & Co aims for ~15% annual return on its storage portfolio

Pulse Analysis

The Nordic power landscape is undergoing a rapid transformation as electricity consumption per capita climbs and renewable generation expands. Finland, a net importer with one of the highest EU per‑capita usage rates—about 15 MWh annually—faces a pressing need for flexible storage to balance imports and domestic generation. Wood & Co’s acquisition of two ready‑to‑build BESS sites in Central Finland positions the firm to capture value from grid‑balancing services while delivering the 15% return it promises investors.

In Sweden, the partnership with Centrica Energy underscores a shift from simple storage deployment to sophisticated market optimisation. By leveraging AI‑driven forecasting and real‑time benchmarking across day‑ahead, intraday, and ancillary‑service markets, Centrica aims to stack revenue streams, with the manual Frequency Restoration Reserve (mFRR) now the dominant source of income for Nordic batteries. However, market participants warn of early saturation in frequency‑control services, prompting operators to diversify into multiple revenue channels and continuously upgrade software controls rather than hardware.

Wood & Co’s dual‑market strategy reflects broader investor confidence in battery storage as a cornerstone of Europe’s decarbonisation agenda. The firm’s 15% target return signals that capital is willing to pay a premium for assets that can navigate the evolving revenue mix and meet stringent grid‑code requirements in cold climates. As larger projects like Alpiq’s 125 MW/250 MWh plant progress, the competitive landscape will intensify, making agile trading and technology upgrades essential for sustained profitability in the Nordic BESS sector.

Deal Summary

Czech investor Wood & Co announced the acquisition of two ready‑to‑build battery‑energy‑storage‑system projects in Finland, totaling 75 MW/150 MWh, from Czech investor BHM Group. The assets, previously owned by BHM Group and developed by Winda Energy, were completed in late March, with financial terms undisclosed. The deal expands Wood & Co Renewables’ portfolio ahead of commissioning in Q2 2027.
