plans to add an additional 300 MW of utility-scalephotovoltaic solar generation by 2021, according to the utility's latest 10-yearsite plan, which would bring its total photovoltaic generation to 633 MW.
subsidiary FPLis currently developingthree 74-MW solar developments that will be in service by the end of 2016 and arelocated in Manatee, Charlotte and DeSoto counties. NextEra management and reiterated inFPL's 2016 10-year site plan, which it filed April 1, that the economics of thethree under-construction solar installations are aided by the fact that they arelocated close to existing electric infrastructure. The addition of these three plantswill roughly triple FPL's current solar generation capacity to 333 MW from 110 MW.
The utilitysaid it has not yet determined siting for the additional planned 300 MW, and itwill continue to analyze other opportunities for additional solar capacity.
FPL describedutility-scale solar photovoltaic as "approximately twice as economical"on an installed dollar-per-kilowatt basis than distributed solar photovoltaic. "[T]hedeclining costs of PV modules has resulted, for the first time, in utility-scalePV in specific locations now being cost-competitive on FPL's system," the utilitystated. "In addition, FPL's analyses of the output from its existing PV facilitiesin DeSoto and Brevard counties have resulted in FPL establishing a methodology fordetermining summer and winter firm capacity values for utility-scale PV facilities."
The site plan addressed FPL's projected incremental resourceneeds from 2016 through 2025. In the latest version, the utility did not predictthe need for a "significant" additional generation resource until 2024and 2025, and as a result, made no decision regarding how to best meet those resourceneeds. FPL's plan did, however, anticipate a large combined-cycle, gas-fired unitat a greenfield site to be added in 2024. FPL currently plans to bring its combined-cycle plant, with a nameplate capacity of 1,633 MW according to SNL Energydata, online in June 2019. Okeechobee entering commercial operation is a key reasonFPL does not anticipate the need for large additional resources for close to a decade.
In its plan, FPL also noted it continues to pursue operatinglicenses for two new nuclear units to be sited at its Turkey Point facility, though it now anticipatesthe earliest practical dates for bringing Turkey Point unit 6 online would be mid-2027,and for Turkey Point Unit 7 mid-2028, which are beyond the time frame addressedin the 10-year site plan.
FPL continues to modernize its gas-fired generation fleet withplans to retire existing gas turbines, including 22 of 24 gas turbines at its site; all 12 gas turbinesat its Port Evergladessite; and 10 of 12 gas turbines at its FortMyers site. FPL is adding five combustion turbines at its Lauderdalesite and two combustion turbines at its Fort Meyers site, all of which are projectedto be completed by the end of 2016.
FPL calculates federal and state energy efficiency codes overthe 2016-2025 period will reduce summer peak load by more than 1,800 MW and reduceannual energy consumption by more than 8,700 GWh by 2025. "In addition, energyefficiency codes and standards significantly reduce the potential for cost-effectiveenergy efficiency that might otherwise have been obtained through FPL's [demand-sidemanagement] programs," the utility stated.
In determining its future needs, FPL said it uses three reliabilitycriterion: a 10% generation-only reserve margin; a 20% total reserve margin forsummer and winter; and an annual 0.1 day/year loss-of-load-probability criterion,which looks at the projected probability a utility might not be able to meet itsentire firm load at some point during a year, due to scheduled maintenance or outages.
