Utilities, grid operators, and technology companies across the United States are expanding efforts to make data centers more flexible in when they consume electricity, a strategy known as demand response. A Duke University Nicholas Institute study estimated that greater data center flexibility could save between $40 billion and $150 billion in grid capital investments over the next decade. The Electric Power Research Institute projects US data center electricity use could rise from 177 to 192 terawatt-hours in 2024 to between 383 and 793 TWh by 2030, while EPRI's Arin Kaye noted surveyed data centers reported peak power reduction potential of 10% to 30%, with some hyperscalers going higher. OpenAI recently agreed to cut electricity draws by up to 1 gigawatt from a planned 3.2-gigawatt Georgia facility during grid stress events, and Alphabet's Google, NVIDIA, and Emerald AI launched the AI Energy Management Alliance last month to advance flexible data center deployment.
The scale of potential grid savings, between $40 billion and $150 billion over ten years according to the Duke University Nicholas Institute, gives regulators and grid operators a concrete financial case for prioritizing flexible interconnection pathways for data centers. Federal regulators issued an order in June directing grid operators to consider new rules that would allow facilities offering demand flexibility to connect faster, which could meaningfully accelerate deployment timelines for operators willing to accept curtailment agreements.
Grid-scale demand flexibility from data centers is an emerging and consequential topic for utility planning; the explainer framing and scale-up question make this a useful policy and infrastructure story distinct from previously published grid-reliability items.
