Tampa Electric said it has completed the second phase of the installation of pollution-controlling equipment at its Big Bend Power Station.

The new selective catalytic reduction equipment is designed to further reduce nitrogen oxide emissions at the plant, a release said.

The $330 million project will make the Big Bend Power Station one of the cleanest coal-fired power stations in the nation, according to Tampa Electric. When completed in 2010, the project will reduce nitrogen oxide emissions at Big Bend by about 90 percent from 1998 levels, the release said.

Big Bend's unit three was the second to receive the new equipment. The project is expected at unit two by May 1, 2009, and at unit one by May 1, 2010.

The project is part of a 10-year, $1.2 billion Tampa Electric program that is the centerpiece of an agreement with the Environmental Protection Agency and Florida's Department of Environmental Protection to dramatically reduce overall emissions from the company's power plants.

Tampa Electric is the principal subsidiary of TECO Energy Inc. (NYSE: TE), an energy-related holding company based in Tampa.
