United States is building data centers faster than grid generation capacity can support; meeting 2030 demand requires $110 billion in new generation resources.
Financial services firm Moody's warns that power availability remains a critical constraint on U.S. datacenter growth, as construction pace outstrips the nation's capacity to expand grid infrastructure. The U.S. has become the epicenter of a global datacenter construction boom, driven by AI demand and the need for compute capacity to train increasingly large foundation models.
According to Moody's, the power required by these facilities will reach 426 terawatt-hours (TWh) annually by 2030—nearly double 2025 levels—citing data from the International Energy Agency. Meeting this demand will require substantial new generation capacity, estimated to cost approximately $110 billion, while adding an estimated $25 billion to $30 billion annually to electricity system costs.
However, rapid datacenter deployment faces significant obstacles. Lengthy permitting processes and extended lead times for key equipment and materials have created delays of up to seven years in some cases. This challenge was highlighted nearly two years ago by management consultancy Bain & Company, which warned that energy companies must significantly boost generation capacity to reverse years of flat or declining demand.
Transmission infrastructure presents a parallel bottleneck. Moody's reports that $80 billion to $115 billion in grid investment through 2030 is already approved or under construction across U.S. power markets, with potential to triple over the following decade. Investment bank Jefferies reported in June that half of the planned U.S. datacenter capacity additions for 2026 are unlikely to launch this year, attributed to power availability, grid connection delays, zoning challenges, and permitting issues.
Texas and other regions able to accelerate development have experienced substantial datacenter construction, intensifying pressure on local grids and prompting some authorities to restrict new connections. Many datacenter operators continue seeking grid connections to minimize costs and secure service reliability, but growing numbers are pursuing alternatives, including on-site behind-the-meter power generation to reduce deployment delays.
The surge in datacenter power demand has inflated electricity prices and customer bills in certain U.S. regions, generating affordability concerns and community opposition. This has driven stricter approval frameworks and project moratoriums in some areas. President Trump introduced a Ratepayer Protection Pledge under which technology and energy companies committed to protecting consumers from rising costs attributable to datacenter expansion.
Moody's projects that large-scale infrastructure investment will ultimately strengthen grid reliability and affordability. Expanded generation capacity will ease longstanding supply constraints and reduce price volatility during extreme weather or peak demand periods. Enhanced transmission networks could improve access to lower-cost generation resources, particularly when datacenter developers or their tenants help finance associated infrastructure investments.
