US Senators Demand Data Centers Disclose Electricity Bills and Grid Load

A new phase of pressure on AI infrastructure is starting in the US: the Senate wants to see exactly how much electricity data centers consume and who ultimately pays for the growing strain on the grid. Senators Josh Hawley and Elizabeth Warren sent a request to the US Energy Information Administration, or EIA, demanding more detailed data on the industry's energy consumption.

What the senators are demanding

On March 26, the senators sent a letter to the EIA asking it to introduce mandatory annual reporting for data centers and other large energy consumers. Their main argument is simple: electricity demand is growing quickly again after a long period of relative stagnation, yet the government still lacks standardized, reliable data to plan grid development properly. Without that foundation, regulators and grid operators are effectively estimating the impact of new facilities almost blind, especially in the fast-growing segment of AI infrastructure.

The EIA already collects a large body of information on the US energy sector: prices, generation sources, energy efficiency programs and general statistics by sector. But that data is split only into very broad categories such as residential, commercial, industrial and transportation consumption. Hawley and Warren want the agency to treat data centers as a separate class of load. They are also interested in the difference between AI computing and ordinary cloud services, because these consumption profiles can differ markedly.

Why the issue has become more urgent

Political pressure on the industry is building from several directions at once. The day before Hawley and Warren's letter, Senator Bernie Sanders and Representative Alexandria Ocasio-Cortez said they were preparing a bill to pause construction of new data centers until Congress agrees on rules for regulating AI. This is no longer a debate about the distant future but a dispute over how fast computing infrastructure can expand and who should bear the costs of that growth.

Authorities have reason to worry. According to the figures cited in the source material, Google's data centers doubled their energy consumption between 2020 and 2024. Looking more broadly, planned new data centers will nearly triple the sector's energy consumption by 2035. For the power system, this means not only additional megawatt-hours but also new load peaks, more expensive grid upgrades and pressure on rates in regions where large facilities are being built.

What data is needed

The senators are asking not for an abstract estimate but for a very specific set of metrics. They want to understand not only total consumption but also how data centers behave over the course of a day, how much they pay, what upgrades their connection requires and whether they take part in mechanisms that help smooth out load peaks.

• Hourly, annual and peak load of large facilities
• Rates that companies pay for electricity
• Which grid upgrades were needed for new connections
• Who pays for those grid upgrades
• Whether data center customers participate in demand response programs

A separate question is how quickly the government can collect such statistics at all. EIA Administrator Tristan Abbey said back in December that the agency is an "important player" in collecting data on data center electricity demand. But he also warned that launching a new full-scale survey is not a quick process: changes to EIA surveys go through an approval procedure at the Office of Management and Budget and require a public comment period.

"Launching a new survey from scratch usually takes about two years,"

EIA Administrator Tristan Abbey said in December.

Abbey did allow that the agency has faster mechanisms: it can run smaller-scale surveys if a sharper, more timely market signal is needed.

Hawley and Warren asked the EIA to respond to their letter by April 9. The political demand for transparency has thus already taken shape, and the question now is how quickly the bureaucratic machine can turn it into a working reporting system.

What this means

The era when data centers could be considered just another "big building full of servers" is ending. For authorities, they are becoming a distinct type of critical infrastructure with its own load profile, and for the AI market this is a signal: continuing to grow without stricter reporting on energy use and grid impact appears unlikely.
