Amazon has signed a 20-year power purchase agreement with Constellation Energy to support upgrades at the Calvert Cliffs Clean Energy Center in Maryland. The deal backs over $3 billion in infrastructure work, including renovations and roughly 190 MW of new generating capacity expected online between 2030 and 2032. Amazon will receive 690 MW of power from the plant, which currently generates about 80% of Maryland's clean energy. The agreement also gives Constellation the revenue certainty to relicense the 1,790 MW nuclear plant for another two decades. All electricity will still flow to the PJM grid, and Amazon has a separate retail supply deal to manage its operations across that 13-state market. This is another sign that large corporate buyers are using nuclear PPAs to secure firm, carbon-free power while helping keep existing reactors running.

Nice to see Amazon putting money behind existing nuclear instead of just claiming clean energy on paper. The 190 MW uprate is modest but the relicense for 20 years is the bigger deal.

Worth noting the new capacity comes online 2030-2032. Interconnection and licensing are long lead items. The 690 MW Amazon gets is basically a slice of the existing output, so the uprate is the real new generation.

Calvert Cliffs provides 80% of Maryland's clean energy. That number shows how hard it is to replace firm carbon-free power. A PPA like this keeps the plant running and adds capacity.

The PPA structure is interesting because it ties revenue certainty to relicensing. That is how you get private capital into long lived assets. Also helps Amazon hedge PJM prices, which are volatile.

The separate retail supply agreement in PJM is worth a closer look. That is how Amazon manages its load in a 13 state market. Nuclear PPAs are becoming a standard tool for big buyers.
