Florida Authorizes Construction of Seminole's Proposed Coal-fired Power Plant

LCG, August 21, 2008--The secretary of the Florida Department of environmental Protection (DEP) signed a site certification order that authorizes the construction of a 750-MW, coal-fired power plant at Seminole Generating Station, located about 50 miles south of Jacksonville in Putnam County, Florida. The existing station is owned by Seminole Electric Cooperative Inc., and the site is already home to two, 650-MW, coal-fired generating units.

Seminole filed a Certificate of Need to construct the electric generating unit with the Florida Public Service Commission (FPSC) in March 2006. The FPSC gave unanimous consent to construct the facility in July of that year. However, site certification was denied by the state in 2007, and the utility appealed. On June 13 of this year, the 5th District Court of Appeal reversed the DEP and directed the agency to issue a certification order approving the new, supercritical coal-fired unit.

A final construction schedule for the new, supercritical unit has not yet been determined. The plan approved by the FPSC in 2006 called for commercial operations to commence on May 1, 2012. In July 2006, the total project was estimated to cost $1.4 billion, including over $250 million to improve emission controls at the existing coal units.
