Investment in the energy transition is shifting from building individual renewable projects to developing larger, integrated businesses. While wind and solar assets remain essential, investors are increasingly focused on companies that can deliver, operate, and improve performance across a portfolio of projects.

Recent data supports this trend. According to a PwC report, global energy, utilities and resources M&A deal value increased by around 27% in 2025, even as overall deal volumes decreased by approximately 2%. At the same time, the number of very large transactions rose sharply, with twenty deals above $5bn compared to just 6 the year before. This indicates that investors are directing capital into fewer, larger businesses rather than backing smaller, standalone projects.

There are several reasons for this change. Developing new energy projects can be slow and uncertain, often affected by planning delays, grid access issues and rising costs. As a result, investors are focusing more on businesses that are already operating and generating revenue. These include companies involved in construction, maintenance, and improving the performance of energy assets, where income is more predictable and can grow over time. Broader industry analysis from MergersandAcquisitions.net also highlights a trend toward fewer deals but larger transaction sizes, showing a more selective approach to investment.

At the same time, PwC reports that attention is shifting toward the wider systems that support renewable energy, such as electricity grids, storage and energy management. These areas are becoming more important as energy systems grow more complex and interconnected, with increased power demand driving investment, according to a separate PwC report.

The result is a clear change in how value is created. Rather than focusing solely on owning individual projects, investors are looking to build businesses that bring together different services and generate steady, recurring income. In today’s market, the most attractive opportunities are those that can scale, integrate services, and play a central role in the broader energy system.
