Wind, Solar & BESS set Q4 clean energy M&A pace

This week felt like Europe’s clean-energy M&A saw three streams converging: auctions reinforced the role of contracted cash flows and brought price certainty, RTB assets delivered speed, and platform deals rounded things off with scale. Italy sat right at the centre of all three, while France kept rotating PV and the UK brought hydrogen and frontier tech into the M&A mix.

This week’s top stories include:

• Finergreen released an analysis of the PV and wind competitive procedures under Italy’s FER X incentive scheme. The first competitive round awarded 7,698 MW of solar and 939 MW of onshore wind, with average tariffs of €56.825/MWh (solar) and €72.851/MWh (wind).
• The week also reaffirmed storage as an infrastructure asset, not an add-on. Deals like ENGIE’s 52 MW RTB BESS in Tuscany (from SUSI-backed ReFeel) and Toki Power’s 150 MW standalone BESS move in Romania showed that even at year-end, appetite for dealmaking remains strong.
• Foresight’s acquisition of a majority stake in flyRen, and Schroders Greencoat taking a majority stake in UK green-hydrogen developer Meld Energy, are clear examples of buyers acquiring teams and backlogs designed to keep producing transactions into 2026.

The “big three” set the tempo: Wind, Solar and Battery Storage in Europe’s Q4 clean energy M&A

In our Q4 M&A and JV curation, the picture is clear: Solar, wind and battery storage remain the “big three” shaping Europe’s renewable energy dealflow.

What stands out isn’t a sudden swing from one technology to another, but balance. Yes, participation shifts month to month, but the overall mix remains remarkably stable for three sectors that are consistently drawing buyers, sellers and partners in the final stretch of 2025.

That stability also matches the broader market backdrop. Solar became the EU’s largest single electricity source for the first time in June 2025, edging out nuclear and wind for that month. And while generation records don’t “explain” M&A, they do reinforce why these segments keep attracting capital: They sit at the centre of Europe’s capacity build-out and system planning.

Battery storage, in particular, continues to strengthen as the flexibility layer around variable generation not as a competing technology, but as an enabler that helps systems absorb more wind and solar. 

• That role is well established in energy-system research, with the IEA explicitly highlighting grid-scale storage as essential for balancing variable renewables and keeping grids stable.

December’s run-rate chart adds a helpful second lens: not just share, but pace. 

Cumulative announcements build quickly early in the month, pause briefly, and then pick up again around the second week. In that view, solar leads the tally, wind follows, and solar integration with storage remains a smaller, steady stream (a reminder that hybrid structures are present and gaining space).Tracking the big three by participation and timing in parallel gives us a simple, optimistic close to the year: These sectors still set the rhythm and even in December, deal announcements can arrive in distinct bursts, not a slow fade into year-end.
