PJM Interconnection, the largest US grid operator, is considering a demand-response program that would pay data centers to curtail load during periods of power scarcity. The proposal would formalize data centers as dispatchable demand-side resources rather than treating them as fixed load. PJM serves 65 million people across 13 states and Washington DC, and data center load growth has become a central variable in its capacity planning.
If adopted, this mechanism would fundamentally change how data centers participate in wholesale electricity markets, creating financial incentives to build operational flexibility into facility design. It also signals that PJM views data center curtailability as a grid reliability tool, not just a commercial option.
