Jan 16 (Reuters) – U.S. utilities are signing concrete supply deals with data-center operators as the artificial-intelligence wave sparks a surge in power demand, paving the way for higher profits in the coming quarters.

Here are some deals announced by utilities in 2024 and 2025: PPL’s Kentucky unit, Louisville Gas and Electric Company, signed a power supply agreement with real estate developers PowerHouse Data Centers and Poe Companies, who will be developing a 400 megawatts (MW) data center campus in Louisville.

The first 130 MW will be available in October 2026.

Constellation Energy signed an exclusive deal with Microsoft to restart one of the units at the Three Mile Island nuclear plant in Pennsylvania.
