Global corporate clean energy procurement experienced a decline in 2025, hitting 55.9 gigawatts (GW), a drop from the previous year’s record of 62 GW. This decrease has been attributed to fluctuating power prices and policy uncertainties, as reported by BloombergNEF.
Among the regions, only the Americas maintained steady clean energy deal volumes, although in the U.S., purchases became concentrated among larger companies. BNEF noted that while the U.S. still leads with 29.5 GW of deals—largely driven by major tech companies turning to nuclear, hydro, and geothermal sources—the number of unique corporate buyers fell by 51% year-on-year, reducing to just 33 participants.
Significantly, major tech firms known as hyperscalers, responsible for massive energy needs for data centers, accounted for nearly half of the clean energy procurement activity last year. Notably, Meta and Amazon led this charge, collectively securing 20.4 GW, including 4.7 GW of nuclear energy.
BNEF highlighted a global trend toward more sophisticated corporate clean energy agreements, influenced by new regulatory changes. For instance, proposed updates to the Greenhouse Gas Protocol’s Scope 2 emissions standards would impose a requirement for hourly tracking and could make claims of 100% renewables more challenging for buyers. In anticipation of these changes, corporations have already engaged in 5.8 GW of co-located and hybrid deals in 2025.
In a related report, BNEF observed that while many clean power technologies became more costly in 2025, battery storage costs have dramatically dropped, marking a significant point in the low-cost trend. Specifically, the global benchmark cost for a four-hour battery project decreased by 27% compared to the previous year, reaching $78 per megawatt-hour (MWh), the lowest since tracking began in 2009.
This decline in battery costs is also fueling the growth of co-located renewable energy projects. In 2025, developers successfully added 87 GW of combined solar and storage, which provided power at an average cost of $57 per MWh.
