Constellation Energy Pre-Market Gain Tops 5% on Google Nuclear Power Deal

The significance lies less in the headline number than in the structure: a 20-year PPA ties a hyperscaler's power demand to existing nuclear capacity rather than to new-build or intermittent renewables, and the PJM interconnection is where data-centre load growth is already straining supply. That template matters for other baseload operators and for how tech firms contract for firm, carbon-free power. Whether similar long-dated nuclear offtakes follow — and how PJM prices the added capacity — is the open question.
