Do you expect the rising cost of renewable energy contracts to increase your household electricity bills?
Solar power purchase agreement (PPA) prices climbed to $64.23/MWh in the third quarter of 2026, marking a 4.9% increase over the prior quarter. This rise reflects a broader market trend where developers are hedging against anticipated Section 232 tariff impacts.
Why it matters
Operators face rising energy costs as equipment pricing increases and developers pivot to expanding existing sites rather than breaking ground on new projects. These constraints are squeezing market access for smaller entities, as hyperscalers now dominate the new-build pipeline.
Average solar PPA prices hit $64.23/MWh in Q3 2026, a 6% year-over-year increase. With hyperscalers accounting for 99% of new-build PPAs in the first quarter of 2026, first-time buyer volume has reached its lowest level since 2016.
The details
Developers are responding to anticipated Section 232 tariffs, which are projected to add $3/MWh to $7/MWh to costs, by repricing more than half of existing solar modules. The market is shifting away from new-build projects toward repowering existing sites to circumvent current procurement and permitting obstacles. These factors have consolidated contract activity among hyperscalers, limiting the entry of smaller corporate purchasers into the renewable energy market.
Timeline
2016: Number of first-time PPA buyers hit a record low.
Q3 2024: Baseline for comparative PPA price increases.
Q1 2026: Hyperscalers accounted for 99% of new-build PPAs.
Early August 2026: Section 232 tariffs were announced.
Q3 2026: Average solar PPA price rose to $64.23/MWh.
Market Landscape
The current solar PPA price hike is a direct reaction to the Section 232 tariffs announced in August 2026. This trend marks a departure from historic market accessibility, as rising equipment costs force developers to prioritize site expansions over new construction.
Business owners should prepare for sustained energy price inflation as PPA costs continue to climb through the near term. Procurement managers should expect reduced supply availability for non-hyperscale buyers as developers focus on existing site repowering.
The takeaway
Operators must monitor the implementation of Section 232 tariffs, as the resulting cost increases are being baked into current power contracts. Review your existing energy procurement strategy and determine if shifting to longer-term or alternative site arrangements is necessary to hedge against rising rates.
