Data centers’ flexible power usage could save the grid billions. Can they scale?
NVDA•Data centers could save $40 billion to $150 billion in capital investments over the next decade by shifting or reducing electricity use during grid stress, a study estimated. U.S. data center electricity use could rise to between 383 and 793 terawatt-hours by 2030.
1. Potential grid savings
Demand response involves data centers temporarily reducing or shifting electricity use during peak demand or grid stress. U.S. data center electricity use could grow from about 177 to 192 terawatt-hours in 2024 to between 383 and 793 terawatt-hours by 2030, while surveyed facilities reported peak power reduction potential of 10% to 30%, depending on facility type.
2. Early projects and rules
Demand response has mostly been used in pilot projects or one-off agreements. OpenAI agreed to cut grid electricity use by up to 1 gigawatt from a planned 3.2-gigawatt Georgia facility during periods of grid stress. Federal regulators in June ordered grid operators to consider new rules for connecting large power users, including faster pathways for facilities offering flexibility. Google, NVIDIA and Emerald AI also launched the AI Energy Management Alliance, aimed at advancing flexible data centers.
3. Scaling challenges
Experts say data centers must adjust consumption without disrupting customers, while utilities and grid operators need tariffs, market incentives and faster interconnection pathways. BMI analyst Alexander Kheder said scaling curtailment agreements across hundreds of new facilities would require significant capital expenditure and coordinated policy frameworks.
