PJM Interconnection's 2026-2027 capacity auction cleared at $15 billion, up from $2.2 billion in the prior year. The 7x jump reflects surging power demand from Big Tech AI data centers and is accelerating investment in nuclear small modular reactors (SMRs).
Key facts
- PJM auction cleared at $15B for 2026-2027, up from $2.2B.
- Google, Microsoft, Amazon committed $40B+ to SMR projects since Jan 2025.
- PJM serves 65M people across 13 states and D.C.
- Northern Virginia hosts >70% of global internet traffic.
PJM Interconnection's 2026-2027 capacity auction cleared at $15 billion, up from $2.2 billion in the prior year According to TradingKey. The 7x price surge is a direct consequence of skyrocketing electricity demand from hyperscale AI data centers, which require 24/7 baseload power—a requirement that intermittent renewables alone cannot meet.
Key Takeaways
- PJM's capacity auction hit $15B, up 7x from 2025, driven by AI data center power demand.
- Big Tech is accelerating nuclear SMR investments.
Why the auction matters for AI infrastructure
PJM operates the grid for 65 million people across 13 states and Washington, D.C., including the data center corridor of Northern Virginia. The region hosts over 70% of the world's internet traffic, and AI training clusters are now the dominant new load. The $15B auction price signals that the grid is structurally undersupplied for the AI buildout, a reality that hyperscalers have been hedging against with direct power purchase agreements.
The nuclear SMR connection
Google, Microsoft, and Amazon have collectively committed over $40 billion to new nuclear SMR projects since January 2025, per public announcements. Google itself has invested $14B in Anthropic and committed $11B/year to SpaceX compute [as previously reported], but its data center power strategy increasingly relies on firm, carbon-free generation. The PJM auction outcome will likely accelerate those SMR timelines, as developers now face a clear price signal for capacity.
What's at stake
AMD and Nvidia are also affected: GPU clusters need guaranteed power to hit utilization targets. If PJM capacity prices remain elevated, it could shift where new AI data centers are built—potentially toward regions with regulated power markets or proximity to SMR deployments.
What to watch
Watch for the next PJM base residual auction in May 2027—if SMR projects don't break ground by then, capacity prices could rise further. Also track Q3 2026 earnings calls from Google, Microsoft, and Amazon for disclosed data center power costs.
