TREASURE COAST ENERGY CENTER, a 411 MW Natural Gas power plant in St. Lucie County, Florida. Operated by FORT PIERCE UTILITIES AUTHORITY, commissioned 2008.
How TREASURE COAST ENERGY CENTER compares
With 411 MW of capacity, TREASURE COAST ENERGY CENTER ranks 38th among the 110 operating power plants Bywatts maps in Florida and 27th of the 55 operating Natural Gas plants in the state. It accounts for about 0.9% of Florida's operating Natural Gas capacity and 0.7% of all operating capacity in the state. Nationally it is the 370th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2008, it is newer than 78% of the 108 operating Florida plants with a recorded commissioning year. It shares St. Lucie County with one other operating plant, ST LUCIE.
EIA-860 lists 2 generators at the site with 411 MW of nameplate capacity, all natural gas fired combined cycle technology. Net generation was 1,839 GWh in 2024 (a 51% capacity factor), down 7% from 2022.

Weather peril exposure
TREASURE COAST ENERGY CENTER is a 411 MW natural gas power plant in St. Lucie County, FL, operated by FORT PIERCE UTILITIES AUTHORITY, commissioned in 2008. St. Lucie County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.4 of 5 at the 85th national percentile. Hurricane is the leading peril, rated Very High by FEMA at the 98th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
St. Lucie County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Hurricane | Very High | 98th | 4.9 of 5 | 0.33 |
| Wildfire | Relatively Low | 69th | 3.8 of 5 | <0.01 |
| Lightning | Very High | 56th | 3.3 of 5 | 84.1 |

|---|---|
| Winter weather | FEMA rating is "No Rating" for this county |
| Ice storm | FEMA rating is "Not Applicable" for this county |
