Corporate adoption of renewable energy across Europe has accelerated sharply over the past eighteen months, with a growing number of businesses not merely meeting sustainability pledges but racing past them as the economics of wind and solar become impossible to ignore.
According to data from BloombergNEF, European corporations signed power purchase agreements covering a record 18.6 gigawatts of renewable capacity in 2025, a 34 per cent increase on the previous year. Early figures for 2026 suggest the trend is accelerating further, with the first half alone matching nearly 70 per cent of last year’s full total.
The driver is increasingly financial rather than reputational. Levelised costs for onshore wind and utility-scale solar have fallen below wholesale electricity prices in most European markets, meaning companies that lock in long-term renewable contracts are often paying less than they would on the spot market.
“Three years ago, sustainability teams drove these conversations. Today it is the CFO’s office,” said Petra Lindström, head of energy advisory at Stockholm-based GreenPeak Consulting. “When the numbers work independently of the green credentials, adoption stops being about corporate virtue and becomes basic commercial discipline.”
The manufacturing and data centre sectors have been particularly active. Industrial users, facing energy costs that can account for 30 per cent or more of operating expenditure, have been among the earliest and largest adopters. Data centre operators, under pressure from both regulators and hyperscale clients to decarbonise, have signed some of the largest single PPAs in European history.
Grid connection queues remain the primary bottleneck. In Germany and the Netherlands, wait times for new renewable connections can stretch beyond four years, a problem the European Commission has pledged to address through revised permitting rules due later this year.
Battery storage deployment is growing in parallel, with 12.5 GW of new storage capacity connected across the EU in 2025. This addresses the intermittency challenge that has historically limited corporate confidence in relying heavily on renewables for baseload operations.
The pace of change is forcing a rethink among energy incumbents. Several major European utilities have announced plans to accelerate coal phase-out timelines, with some moving target dates forward by as much as five years. As Lindström put it, “The energy transition is no longer being led by policy. It is being led by the spreadsheet.”
