Energy Europe 5 min read

Europe’s energy transition continues to drive investment and M&A activity, as renewable energy capacity expands and dealmaking gains momentum across the region.

According to Boston Consulting Group (BCG), European M&A transaction value rose 43% to USD 541 bn in the first eight months of 2026, the fastest growth among major global regions. 

At the same time, the European Commission reported that EU greenhouse gas emissions declined 1.6% in 2025, while combined wind and solar capacity reached 611 GW, representing approximately 49% of the bloc’s total electricity generation capacity.

Against this backdrop, recent transactions include Ecosuntek’s investment in Italy’s H2-Era Green Valley, European Energy’s sale of a 50% stake in its Danish solar portfolio, and acquisitions across solar PV, battery storage and electricity grid infrastructure. 

And the Ideals-M&A Community team compiled the new deals announced during October in the renewable energy sector in Spain and Portugal – and PV magazine has published the full list.

Finally, I’m keen to get to know more of our M&A Teaser audience, so please connect with me on LinkedIn.
