US clean energy power purchase agreement markets are being reshaped by three converging forces: rapid load growth, rising market complexity and heightened policy uncertainty. Rising demand from AI and hyperscale data center operators is colliding with grid congestion, curtailment risk and longer, less predictable interconnection timelines.

After a softer close to 2025, contracting momentum picked up in early 2026 as buyers and developers moved to secure bankable projects amid tighter tax-credit scrutiny and execution risk. The market is increasingly rewarding firm and hybrid supply, with hyperscalers driving a growing share of deal activity.
