The work force reductions are limited to the Florida utility and do not impact the company's operations in North and South Carolina, at least not yet, said Mike Hughes, a Progress Energy spokesman in North Carolina.
"We've seen a slowdown in the Carolinas, but not to the extent we've seen in Florida," Hughes said.
The St. Petersburg utility employs 4,300 workers in Florida.
No information was released on the number of workers likely to be affected.
