Constellation has signed a 20-year agreement covering 270 MW of energy, capacity and nuclear attributes from its existing reactor fleet, with deliveries due to begin in 2028.

Disclosed in the company’s 9 November results, the contract is its first transaction under the Peak+ offering. Supply is unit-contingent, meaning it depends on the availability of the underlying generation. The announcement does not name the customer or the supplying nuclear units.
The 270 MW agreement concerns output from existing reactors; it should not be counted as 270 MW of newly built nuclear capacity. Constellation describes Peak+ more broadly as combining new capacity and demand response with tailored energy products.
In a separate transaction disclosed in the same update, Constellation agreed to acquire RISEC Holdings from Shell Energy North America for $715 million, subject to customary price adjustments. RISEC owns the 609 MW Rhode Island State Energy Center, a combined-cycle gas-fired power plant serving the ISO New England wholesale market.
The acquisition remains subject to regulatory approvals and other closing conditions. It would add to Constellation’s merchant generation portfolio, but ownership has not yet transferred under the announced agreement.
The two developments give the company additional contracted nuclear demand and a proposed addition to its gas-generation fleet. Earlier Amazon and Google nuclear agreements mentioned in the results were announced in September and October and are not new contracts from this update.
