OpenAI data centers will cut power use when the grid is strained

OpenAI launched the Grid Protectors Program on Monday 2 November. Its future US compute campuses will reduce electricity demand when extreme weather or another emergency strains the grid. OpenAI will agree with each utility how much demand it cuts, how fast and for how long, so terms will differ by site.

OpenAI data centers have so far promised this only in Georgia. The planned campus in Effingham County, known as Project Camellia, is the pilot.

What Georgia already has

• a 25-year agreement with Georgia Power for up to 1,000 MW of flexible demand response;
• the utility can cut the power it delivers during certain periods;
• OpenAI pays the full infrastructure and electric-service costs for the project.

OpenAI compares the 1,000 MW to the average demand of about 700,000 households. Georgia Power expects the campus to need about 3,200 MW, delivered in phases from 2028 to 2032. By our count, OpenAI can switch off about 31% of the site's planned load.

Georgia Power calls the deal "among the largest single-facility demand-response commitments in the country" and says it lets the utility build fewer new power plants. It also projects about $950m a year in customer savings from 2029, but that figure covers its whole portfolio of large-load contracts, not the OpenAI campus alone.

How the cuts work

OpenAI says it may run on-site generation or storage when grid operators need it, and use batteries and power controls to smooth swings in demand. Much of that storage depends on cells now caught up in the US battery ban. OpenAI has not committed to on-site systems at every campus, and the pledge covers campuses it develops itself, not capacity it rents from cloud partners.

“Flexibility will be a core part of how we build and operate future campuses.”

John McCarrick, OpenAI's head of energy policy, told Axios that about a year ago a large hyperscaler was still "defending the five nines", the industry's 99.999% uptime target. He doesn't think anyone does that now. Five nines allow about five minutes of downtime a year, while the Georgia deal lets the utility cut up to a third of the campus load.

Why now

Axios describes public and political backlash over data center power demand as a threat to the industry's expansion plans. In Mississippi, xAI offered to buy 418 homes near its data center if owners drop their claims. A Senate permitting bill would let states require data centers to limit power use at set times as a condition of grid service.

Crypto has run this model for years: in Texas, bitcoin mining firms are paid by grid operator ERCOT to switch off during demand peaks. OpenAI is now offering a utility the same lever at AI scale.

OpenAI itself says flexibility does not replace new generation and transmission. If you live near a planned campus, the Georgia contract shows what to ask your utility: how many megawatts the operator can shed, and who pays for the new lines.

OpenAI has not published terms for any campus beyond Georgia or a start date for the wider programme.
