Power purchase agreement prices for solar projects in North America fell in the second quarter of 2026 for the first time in two years, while wind prices continued to rise ahead of a major federal tax credit deadline, according to LevelTen Energy.
North American solar power purchase agreement rates dropped 4.8% during the second quarter of 2026, marking the initial quarterly cost reduction for solar in two years, as wind power purchase agreements climbed 5.5% over the same timeframe. Marketplace operator LevelTen Energy released these findings in its Q2 2026 report, which evaluated 266 pricing proposals spanning 185 renewable energy sites across six Independent System Operators amid shifting market dynamics, federal permitting obstacles, and changing tax credit rules.
The continent-wide decrease in solar pricing was primarily led by a sharp cost reduction within the California Independent System Operator footprint. California was responsible for over half of the aggregate continental price drop, and omitting California from the calculations reduced the overall continental average decline to 1.8%. This downward shift highlights a wider cooling of corporate purchasing interest, where technology companies and large data center operators continue buying substantial quantities of renewable power, but commercial and industrial purchasers display hesitation.
Purchasers have slowed or paused acquisition strategies due to high agreement expenses and ongoing ambiguity surrounding proposed modifications to Greenhouse Gas Protocol Scope 2 accounting rules. Consequently, project developers are refining contract provisions to stay competitive in a landscape increasingly favoring buyers. Meanwhile, continental benchmark indices for wind power purchase agreements rose 5.5% quarter over quarter and stand 17.5% higher compared to the previous year.
Upward pricing pressure on wind energy stems from high fuel expenses, costly logistics, and continuing federal approval hurdles. A principal constraint limiting new wind generation capacity involves the Department of Defense maintaining a near-total pause on issuing national security mitigation agreements since August 2025. This restriction has severely compressed the inventory of buildable wind installations, compelling buyers to pay a premium to secure fully permitted assets.
The evaluation emphasizes an important industry threshold: the July 4 tax credit qualification deadline mandated by the One Big Beautiful Bill Act. Following this cutoff, the volume of United States projects eligible for tax credits will effectively freeze. LevelTen cautions that as subsidized capacity becomes scarcer, overall agreement pricing will likely enter elevated and unprecedented levels. Additionally, projects qualifying for tax credits must reach commercial operation and enter service prior to the conclusion of 2030 to preserve their status, creating urgency for corporate entities to conclude negotiations and help developers achieve financial close.
Although contract costs have surged as much as 151% since 2020, LevelTen research shows that corporate buyers who postponed purchasing in anticipation of lower expenses incurred estimated financial impacts ranging from $32 million to $65 million per 200 MW installation across major regional markets. Despite market fluctuations, LevelTen reports that virtual power purchase agreements remain among the most effective mechanisms for corporate entities to safeguard against grid price volatility and macroeconomic exposure. Across the continent, Q2 2026 price benchmarks averaged $61.40 per MWh for solar, $83.79 per MWh for wind, and $72.60 overall, while 25th percentile offer values reached $52.65 for solar and $61.19 for wind.
