NEW YORK, May 9 (Reuters) - Constellation Energy ( CEG )

is considering adding new nuclear power generation on its

existing U.S. sites, which could be spurred by data centers and

other large power load customers, executives with the

Maryland-based energy company said on Thursday.

Constellation, which is the largest operator of U.S. nuclear

energy, said it is exploring the possibility of small modular

reactors and other power technology on its existing sites that

would be funded through long-term power purchase agreements with

customers.
