Date 2026-10-06 · announcement Figure measures generation capacity Stated dates (targets and terms, not events) delivery target: first uprate (2028) Stage contracted Quantity exact · 890 megawatts (MW) of new nuclear capacity Scope and limits Announced; 890 MW is incremental uprate capacity to be built, not power delivered. The release ties the agreement to Google's 'growth' in PJM, not to a named data centre. The concurrent 15-year 2,700 MW supply agreement is a separate record (recorded separately).

Status and meaning Editorial status. Not reviewed by an editor . An exploratory record that no editor has accepted. This status does not say whether a person has read any linked passage. Each evidence record above shows how it was checked.
Relation. A stated agreement on electricity supply, a power purchase, a plant restart or the development of generation, at the stage the parties state. It is not delivery of power, and an agreement to explore is not a contract.
Date. Date of the announcement, as the source gives it.
