Tampa Electric considering building 230-kV line

Tampa Electric may file a petition of need with Florida regulators in August, proposing a 40-mile, 230-kV transmission line.

“We are looking at needing more electricity in five years and our proposal that we’re considering is to expand the Polk Power station,” a company spokesperson told TransmissionHub May 1. “If we decide that that’s the most cost-effective solution, then we would need the transmission line to bring the electricity from the power plant out to our grid.”

If expansion is determined to be the most cost-effective option, Tampa Electric would expand the Polk Power station by 2017, and build the new Polk Power to Fishhawk substation line from the power plant in southwestern Polk County, Fla., to the company’s Fishhawk substation in southeastern Hillsborough County, Fla.

The company also would build a substation near Balm Boyette Road and Aspen Avenue. A 10-mile portion of an existing 230-kV line in the Pierce and Bradley areas of Polk County would also need to be relocated to improve reliability, the company added.

The company is studying five proposed routes for the line, the spokesperson said.

If approved, construction on the line would begin in 2014 and end in late 2016, the spokesperson said, adding that the project’s cost is not known at this time.

The company held three open hearings in April, the spokesperson said.

According to a March statement, Tampa Electric issued a request for proposals soliciting competitive bids to address the company’s future power needs. The expansion of the Polk Power station by about 460 MW would convert the four existing simple-cycle natural gas units to combined-cycle units by January 2017. Proposals to the RFP must be received by May 22, with a short list of proposals expected to be announced in June, the company added.
