TALLAHASSEE, Fla. (AP) — State regulators have approved requests from Florida’s two largest electric utilities to continue passing future nuclear facility costs on to their customers in 2013.

The five-member Public Service Commission on Monday unanimously approved a decrease for Florida Power & Light Co. and increase for Progress Energy Florida.

FPL sought $151 million, which will be $1.69 per month for a typical residential customer using 1,000 kilowatt hours. That’s 51 cents less than this year’s nuclear cost recovery charge.

Progress will get $143 million. That will increase the current charge for a 1,000-kilowatt hour customer by $1.93 to $4.79 per month.

Utilities normally cannot pass on such expenses until new or renovated plants go into operation. State law, however, makes an exception for nuclear facilities to encourage that form of power generation.
