Google and Constellation back 890 MW of extra nuclear power from existing plants
Google and Constellation signed a 20-year power purchase agreement supporting upgrades at existing nuclear units. The programme is intended to add 890 MW to the PJM grid, with initial increases expected in 2028. The companies estimate investment above 4.3 billion dollars and separately agreed to purchase electricity from existing generation.

Existing reactors are set for more output
Google and US electricity producer Constellation agreed on 6 October to support an additional 890 MW of nuclear capacity through upgrades to existing reactors. A 20-year power purchase agreement backs the programme on the PJM electricity grid. The companies estimate more than 4.3 billion dollars of investment, with the first capacity increases expected in 2028.[1], [2]
The work covers 11 units at 6 sites in Illinois, Pennsylvania and New Jersey. Turbines, steam generators and digital controls are among the equipment to be improved. Increasing output at these operating units expands the fleet’s generating capacity within its existing sites. The programme is aimed at supplying additional firm electricity to a grid serving 67 million people.[1]
A separate contract covers existing generation
Alongside the uprates, the companies signed a separate 15-year agreement for 2700 MW from existing generation in PJM. Its contracted output comes from plants already operating on the system. The longer 20-year contract instead supports the equipment investments needed for additional nuclear production. Both commitments form part of the companies’ long-term electricity collaboration.[1], [2]
Computing demand and operations join the agreement
Constellation estimates that the investment will support 4400 existing jobs and create 7200 construction jobs. Those employment numbers are company projections for the investment programme and the building period.[1]
Google plans to reduce non-critical computing workloads when the grid is under stress. This demand-flexibility component sits alongside plans to examine further generation, storage and demand-management opportunities. The strategic framework gives priority to near-term work in PJM while allowing the companies to evaluate additional projects.[1]
Constellation also selected Google Cloud and Gemini Enterprise for a 5-year technology alliance. The planned applications include generation planning, dispatch and cybersecurity, as well as tools for managing construction and plant operations. The companies described the technology as part of their effort to improve grid resilience and electricity affordability; those benefits remain stated objectives of the new collaboration.[1], [2]
