Worldwide corporate clean power procurement fell in 2025 to 55.9 GW, from a record 62 GW in 2024, due to a mix of power prices and policy risks, according to a Thursday report from BloombergNEF.
The Americas were the only region globally where clean energy deal volume didn’t drop, but clean energy purchases in the U.S. became more consolidated among larger companies, BNEF concluded.
“The U.S. is still the largest market, hosting a record 29.5 GW of deals, driven by Big Tech’s pivot to nuclear, hydro and geothermal,” BNEF said in a press release. “However, the largest technology firms signed most of the deals, with smaller players becoming less active, as project costs and policy uncertainty rose. The number of unique corporate buyers in the US dropped 51% year-on-year to just 33.”
BNEF found that hyperscalers, which are pursuing an unprecedented buildout of energy-hungry data center infrastructure, were outsized drivers of clean energy purchasing last year — 49% of that activity was from Meta, Amazon, Google and Microsoft.
Meta and Amazon in particular led clean energy buying in 2025, contracting a combined 20.4 GW, BNEF said, including 4.7 GW of nuclear power.
BNEF said that there is a global push for “more sophisticated corporate clean energy deals” which is “also being driven by regulatory shifts,” such as the Greenhouse Gas Protocol’s proposed updates to its Scope 2 emissions standards which would require hourly tracking — making 100% renewable claims “harder to justify for most buyers.”
“Corporate clean energy buyers are already preparing for this change, with 5.8 GW of co-located and hybrid deals tracked in 2025,” BNEF said. “As battery costs continue to decline, these deal structures are expected to become the new standard for corporate procurement.”
In a Wednesday report, BNEF found that most clean power technologies became more expensive in 2025, while the cost of battery storage “plummeted to new lows,” sending “mixed signals.”
“BNEF’s global benchmark costs for solar, onshore wind and offshore wind costs all rose in 2025, reversing the downward trend seen in recent years, due to a combination of supply chain constraints, poorer resource availability and market reforms in mainland China,” BNEF said.
The global benchmark cost for a four-hour battery project, on the other hand, fell 27% year-on-year to $78/MWh in 2025 — “a record low since BNEF began tracking costs in 2009,” according to the release.
“Falling battery costs are also accelerating the buildout of co-located renewable projects,” BNEF noted. “In 2025, developers added 87 gigawatts of combined solar and storage, delivering power at an average of $57/MWh.”
