The planned campus in Effingham County, Georgia, is intended as a pilot. The announced agreement provides up to 1,000 megawatts of flexibility. That is available power flexibility, not energy already saved.
Arrangements are to specify each site's reduction capability and activation conditions. OpenAI says it intends to cover infrastructure and electricity-service costs for its Georgia project.
The programme concerns future facilities. The sources therefore establish neither curtailment already delivered under this announcement nor an actual reduction in household bills. Those outcomes depend on commissioning and implementation of the agreements.
