Duke Energy Florida retires oil-fired Turner peaking plant

The Florida Department of Environmental Protection issued a June 1 correction to the Title V air permit for Duke Energy Florida‘s Turner peaking plant showing that the plant was retired as of April 1 of this year and that the permit officially expired on that date.

The utility had requested the correction on May 24. The plant site is located in Volusia County.

This facility consisted of four simple cycle combustion turbine peaking units (CTP) Nos. 1 and 2 and CTP Nos. 3 and 4, all of which were pre-NSPS (New Source Performance Standards) emissions units. Air pollutant emissions from the CTPs were not controlled and each combustion turbine exhausted through a separate stack. All four CTPs were permitted to operate 8,760 hours per year and could only combust new No. 2 fuel oil.

CTPs 1 and 2 were each rated at 18 MW, while CTPs 3 and 4 were rated 82 MW apiece. CTPs 1 and 2 were General Electric models that went commercial in 1970, while CTPs 3 and 4 were Westinghouse models that went commercial in 1974.

In a Ten-Year Site Plan that Duke Energy Florida filed April 1 with the Florida Public Service Commission (FPSC), the utility said it continued to look ahead to the projected retirements of several of the older units in the fleet, particularly combustion turbines at Higgins, Avon Park, Turner and Rio Pinar as well as the three steam units at Suwannee. Turner Unit P3 was retired July 2015. The Rio Pinar and Turner Units P1, P2 and P4 showed anticipated retirement dates in 2016. Suwannee steam units 1, 2 and 3 are projected to retire in November 2016. Continued operations of the peaking units at Higgins and Avon Park are planned until the year 2020. There are many factors which may impact these retirements including environmental regulations and permitting, the unit’s age and maintenance requirements, local operational needs, their relatively small capacity size and system requirement needs.
