NEW YORK -(Dow Jones)- Florida regulators on Tuesday approved Progress Energy's request for a $6.5 million interim electric rate increase.

Progress Energy Florida, a utility owned by Progress Energy Inc. (PGN), Raleigh, N.C., said it needed the short-term rate increase to cover the cost of doing business until the Florida Public Service Commission decides whether the utility can raise rates by $500 million in 2010. The increase would allow Progress to recover costs associated with upgrades to the electric grid and to the utility's power plants.

Because rate proceedings can take several months, utilities sometimes ask regulators to approve temporary rate increases. In a February letter to the Public Service Commission, Jeffrey Lyash, Progress Energy Florida's president and chief executive, said the utility "may not be able to continue to provide reliable, efficient electric service to its customers" without the proposed interim rate increase.
