Lawmakers Question Data Center Energy Consumption
▼ Summary
– Senators Elizabeth Warren and Josh Hawley are urging the U.S. Energy Information Administration to collect and disclose comprehensive annual energy-use data from data centers.
– There is widespread public concern that the massive energy demands of data centers could increase electricity costs for consumers, influencing elections in some states.
– Currently, no federal agency collects specific data on data center energy use, and such information is often considered proprietary or obscured by behind-the-meter power installations.
– Utilities use data center energy information for growth forecasts, but experts warn that project double-counting can lead to inflated and inaccurate demand predictions.
– The EIA has launched a voluntary pilot program to collect data, but the senators are pressing for details on making surveys mandatory and including behind-the-meter power information.
A bipartisan effort is underway in Washington to bring greater transparency to the energy consumption of data centers. Senators Elizabeth Warren and Josh Hawley have jointly requested that the U.S. Energy Information Administration begin collecting and publishing detailed annual reports on how much power these facilities use. In a letter to the agency, the lawmakers argued that such data is critical for reliable grid planning and for crafting policies that shield American households from bearing the cost of surging industrial electricity demand.
This political push reflects growing public anxiety. As the data center boom expands nationwide, voters in states like Virginia and Georgia have expressed concern that the massive energy requirements of these facilities could drive up their utility bills, influencing recent electoral outcomes. In response, Hawley recently cosponsored legislation with Senator Richard Blumenthal that would mandate data centers to provide their own power generation. Separately, former President Donald Trump recently hosted tech executives at the White House to sign a non-binding pledge for companies to cover their own data center energy costs.
Experts agree that reliable information is the foundation of any solution. “If we’re worried about ratepayers paying data-center energy costs, then knowing how much energy data centers are using is a necessary part of that calculation,” says Ari Peskoe of Harvard Law School’s Environmental and Energy Law Program. “It’s not the only piece of information you need, but it certainly is a piece of the puzzle.”
Obtaining accurate figures, however, is notoriously difficult. No federal agency currently compiles specific data on data center energy use, and details on water or electricity consumption are often treated as proprietary business secrets, disclosed only voluntarily. The trend toward behind-the-meter power, where facilities install their own generation separate from the public grid, further complicates any attempt to calculate total consumption.
Even utility companies, which have access to local usage data for forecasting, face challenges. Data centers frequently solicit proposals from multiple providers, leading to instances of double-counted projects and inflated forecasts for “phantom” facilities that never get built. The CEO of retail electricity provider Vistra noted last year that utilities may be overestimating future electricity demand by a factor of three to five.
Recognizing the data gap, EIA Administrator Tristan Abbey stated in December that his agency would be essential in providing objective analysis to policymakers. This week, the EIA announced a voluntary pilot program to gather energy use information from nearly 200 data center operators in Texas, Washington, and Virginia. The survey will cover energy sources, electricity consumption, and technical details about servers and cooling systems.
While applauding this initial step, Senators Warren and Hawley have pressed the EIA for more details in their letter. They seek clarity on whether future surveys will be mandatory and if they will capture data on behind-the-meter generation. This information, the senators contend, is vital for holding large technology companies accountable, ensuring they follow through on recent pledges to prevent consumers from subsidizing their data center electricity use.
