Tampa, FL, July 21, 2007 — Tampa Electric filed a petition with the Florida Public Service Commission (FPSC) to demonstrate the company’s need to build their proposed 632-megawatt Polk Unit 6, an integrated coal gasification combined cycle (IGCC) facility. The new unit would be located on the site of its existing Polk Power Station, a site selected by an independent task force.
The company currently estimates the cost for Polk 6 to be approximately $2 billion, which includes an estimated $1.6 billion for engineering, procurement and construction, with approximately $400 million in additional related costs, such as transmission infrastructure, environmental permitting, project management, staffing and training, and contingency costs.
The company expects that the FPSC will hold a hearing in the October 2007 timeframe and issue a decision shortly after the hearing has concluded.
Through a chemical process, IGCC technology converts solid fuels into a synthesis gas, which is burned in a conventional combustion turbine to produce electricity. Polk 6 will be designed with the capability to use biomass as a fuel, a technology that has been successfully tested in the company’s existing Polk Unit 1. The heat produced by the combustion turbines is captured to produce steam, which powers a steam turbine that also produces electricity. This process results in fewer emissions of nitrogen oxides, sulfur dioxide, particulates and mercury than any other coal-fired technology.
