MARTIN, a 4,318 MW Natural Gas power plant in Martin County, Florida. Operated by FLORIDA POWER & LIGHT CO, commissioned 1994.
How MARTIN compares
With 4,318 MW of capacity, MARTIN is the largest of the 110 operating power plants Bywatts maps in Florida and the largest of the 55 operating Natural Gas plants in the state. It accounts for about 9.7% of Florida's operating Natural Gas capacity and 6.8% of all operating capacity in the state. Nationally it is the largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1994, it is newer than 52% of the 108 operating Florida plants with a recorded commissioning year. Its operator, FLORIDA POWER & LIGHT CO, runs 13 operating plants in Florida totaling 25,806 MW.
EIA-860 lists 11 generators at the site with 2,449 MW of nameplate capacity, all natural gas fired combined cycle technology (this page's HIFLD capacity figure is 4,318 MW). Net generation was 7,499 GWh in 2024 (a 35% capacity factor), down 21% from 2022. Its generators came online between 1994 and 2005.

Weather peril exposure
MARTIN is a 4,318 MW natural gas power plant in Martin County, FL, operated by FLORIDA POWER & LIGHT CO, commissioned in 1994. Martin 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.
Martin County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Hurricane | Very High | 98th | 4.9 of 5 | 0.31 |
| Wildfire | Relatively Moderate | 77th | 4.1 of 5 | <0.01 |
| Lightning | Relatively High | 70th | 3.8 of 5 | 89.9 |

| Riverine flooding | Relatively Moderate | 15th | 1.6 of 5 | 0.57 |
| Earthquake | Very Low | 3rd | 1.1 of 5 | <0.01 |
| Hail | Relatively Low | 2nd | 1.1 of 5 | 0.84 |
Perils not assessed in Martin County
These perils carry no usable National Risk Index figure for this county, so they are excluded from the scoring rather than scored zero. A zero would claim the peril was assessed and found benign.
| Peril | Why it is not scored |
|---|---|
| Winter weather | FEMA rating is "No Rating" for this county |
| Ice storm | FEMA rating is "Not Applicable" for this county |
