The latest resource plan of Tampa Electric is very similar to the plan presented in 2014, with the utility in the process of constructing incremental capacity of 463 MW winter and 459 MW summer as part of the Polk 2 combined cycle (CC) conversion project, which has a commercial operation date of Jan. 1, 2017.
In 2017, Tampa Electric will meet its intermediate load needs by converting Polk Power Station’s simple cycle combustion turbines (Polk Units 2-5) to a waste heat recovery natural gas combined cycle (NGCC) unit with a capacity of 1,063 MW (summer). The incremental capacity gain from the conversion is 459 MW (summer).
In addition, Tampa Electric also plans to build a future combustion turbine (CT) of 204 MW (summer) of capacity to meet reserve margin needs in the summer of 2021, said the utility in a Ten-Year Site Plan filed April 1 at the Florida Public Service Commission. No specific site for that CT is named. Any future generating capacity additions could occur at H.L. Culbreath Bayside Power Station, Polk Power Station, or Big Bend Power Station.
