Short-term power purchase agreements are gaining traction in the renewables sector as buyers seek greater flexibility and risk mitigation amid rising solar and wind prices.
Solar PPA prices increased by 4.7% in the first quarter of 2026, up 13% year-over-year, according to an April 14 report by PPA marketplace LevelTen Energy Inc. Wind PPA prices rose 8% over the same period, or nearly 24% year-over-year, fueled by ongoing interconnection bottlenecks, labor shortages, tariffs and permitting gridlock.
Wind prices in particular are expected to remain elevated amid ongoing policy uncertainty stemming from the Trump administration's executive actions on federal land approvals, LevelTen said.
The average PPA length for a new-build project remains 14 to 15 years, LevelTen Marketplaces Senior Vice President Rob Collier said in an interview.
In a Feb. 9 report, S&P Global Energy CERA analysts wrote that three- to five-year PPAs allow both buyers and sellers to "avoid locking in prices."
"This may be especially beneficial for procurers for data centers as they weigh rising PPA prices and market tightness against the opportunity cost of later market entry," S&P Global Energy CERA analysts wrote.
S&P Global Energy attributed the heightened attention to short-term PPAs in part to hyperscalers' "financial heft and growing capabilities," including "in-house trading capacity, becoming active in wholesale power markets and even directly acquiring generation assets."
Meta Platforms Inc., Google LLC, Amazon.com Inc. and Microsoft Corp. still drive the majority of PPA activity, accounting for 90% of volumes from the start of 2026 through Feb. 23, according to a March 30 S&P Global Energy Horizons report.
Collier said "we are hearing more interest in shorter tenor PPAs on the buy side," but said brand new projects still require longer contracts to obtain financing from banks and long-term equity sponsors.
Analysts agree that shorter term contracts might be a better fit for operational assets rolling off long-term PPAs, which have "three to five years of operational life without any additional capital outlays."
Repowering solar and wind assets, however, may still require traditional project finance.
"Some [repowerings] are so substantial they're taking a wind project really down to the foundation and building it back up," Collier said.
LevelTen said in an August 2025 report that solar PPA prices would need to increase by at least $8 to $17.50 per megawatt-hour to compensate for reversed federal tax credits, but Collier said "that's actually not something we're hearing a lot about from developers."
Analysts at CreditSights said in an April 13 note to clients that as the US-Israel war with Iran drives energy prices higher and Democrats potentially regain a majority in the House of Representatives in November, they "expect any and all of these tax credits to come back in 2027 with bipartisan support and or Democrats making them a condition of any new legislation."
