Seminole Electric Cooperative is one of the largest generation and transmission cooperatives in the U.S. Its primary mission is to provide reliable, competitively-priced wholesale electric power to its 10 Member systems, which include four of the largest distribution cooperatives in the nation.

Approximately 1.7 million individuals and businesses in portions of 45 Florida counties rely on Seminole's Member systems for electricity. Seminole is led by an experienced management group and governed by a 30-member board of trustees. The board is comprised of three representatives from each Member system.

Seminole's resources include the Seminole Generating Station (SGS) in northeast Florida and the Richard J. Midulla Generating Station (MGS) in south central Florida. Seminole also owns nearly 300 miles of transmission line that interconnect its generating facilities to Florida's transmission grid.

Seminole Generating Station went into commercial service in 1984. It consists of two 650 megawatt coal-fired generating units. This facility is located in Putnam County, near the St. Johns River, south of Jacksonville. SGS has more than $530 million invested in pollution control equipment making it one of the cleanest coal facilities in the U.S.

Richard J. Midulla Generating Station, located in Hardee County, northwest of Wauchula, is an 810 megawatt facility. It uses natural gas as its primary fuel source but can utilize ultra low sulfur fuel oil as well. The MGS 500 megawatt combined cycle unit began commercial operation in 2002. An additional 310 megawatts of peaking capacity went into service at this location in December 2006.

In addition to its generation resources, Seminole also contracts for capacity and energy through purchase agreements with other utilities and independent power producers. These resources reflect a mix of technologies and fuel types, including one of the state's largest renewable energy portfolios. The diversity in Seminole's generation mix reduces exposure to changing market conditions, helping keep rates competitive.
