President Biden will sign an executive order Tuesday aimed at reducing barriers to construct new data centers and the accompanying energy infrastructure needed to power the development of artificial intelligence (AI).

The executive order directs the Department of Energy and Department of Defense to select federal sites that can be leased to companies to build “gigawatt-scale” data centers, while employing the Department of the Interior to identify available lands to build clean energy infrastructure to support the new data centers.

The administration also aims to prioritize the “full and expeditious” permitting of these sites and help facilitate the development of transmission lines and interconnection to the grid.

“Currently, the market for AI infrastructure is deeply constrained,” Navtej Dhillon, deputy assistant to the president and deputy director of the White House Economic Council, told reporters on a call Monday.
