Florida's investor-owned utilities anticipate needing new gas-firedand renewable generation resources over the next decade, according to 10-year siteplans filed with state regulators.
's plans toadd generation over the 2016-2025 period include installing inlet chilling for summercapacity uprates at its 2,199-MW HinesEnergy Center; adding a combined-cycle facility in Citrus County, scheduled to in 2018 at a capacity of 1,640MW; acquiring from the Energy combined-cycle unit;and adding five combustion turbine units at an undesignated site, four units in2024 and one unit the following year.
DukeEnergy Florida will also obtain additional summer capacity by purchasing GeorgiaPower Co.'s interest in a unit at the Intercession City plant in Osceola County, Fla.
Additionally,the Duke Energy Corp.subsidiary said it plans to install 550 MW of solar photovoltaic generation capacityover the next 10 years.
To complywith the U.S. EPA's Mercury and Air Toxics Standards, or MATS rule, Duke Floridahas switched two steam units at its Ancloteplant and three steam units at its SuwanneeRiver plant to natural gas, and residual fuel oil is no longer availableat these two plants. The Florida Department of Environmental Protection grantedDuke Florida a one-year extension to comply with MATS at its Crystal River units 1 and 2, where the utility plansto burn MATS-compliant coal and then retire the units once the Citrus County combined-cyclefacility comes online. Duke Florida was also granted an extension to comply withMATS for Crystal River units 4 and 5, which will provide time to bring those unitsinto compliance with the rule.

In its10-year site plan, Gulf Power Co.anticipates being able to meet reserve margin requirements until June 2023. Theutility has a PPA with Shell Energy North America for 885 MW of firm capacity froma combined-cycle unit in Alabama, which expires May 24, 2023. The schedules in GulfPower's plan reflect the need for combustion turbine capacity upon expiration ofthe PPA with Shell. Gulf Power has also executed PPAs with renewable power sourcesincluding municipal solid waste, wind and solar. "This strategy of supplementingGulf's development of long-term capacity resources with shorter-term power purchaseshas proven to be effective over the years, and Gulf will continue to follow thisstrategy in the future when appropriate and cost-effective to do so," the utilitystated. Gulf Power and GeorgiaPower are subsidiaries of SouthernCo.
subsidiary 's 10-year siteplan also showed few changes fromwhat it filed in 2015. As of December 2015, Tampa Electric built a 1.6-MWphotovoltaic solar array at the Tampa International Airport. The utility is alsoadding 463 MW of winter capacity and 459 MW of summer capacity through its 2 combined-cycle conversionproject, which has a commercial operation date of May 2017. Also associated withthe Polk plant is a new 51-mile, 230-kV transmission line scheduled to be placedinto service in January 2017 at a cost of $96 million.
TampaElectric also plans to add18 MW of solar at its Big BendCT plant, with a projected commercial operation date of May 2017.
Additionally,Tampa Electric maintained the need to build future combustion turbines to meet reservemargins in the summers of 2020 and 2023.
