LARSEN MEMORIAL, a 149 MW Natural Gas power plant in Polk County, Florida. Operated by CITY OF LAKELAND - (FL), commissioned 1956.
How LARSEN MEMORIAL compares
With 149 MW of capacity, LARSEN MEMORIAL ranks 48th among the 110 operating power plants Bywatts maps in Florida and 35th of the 55 operating Natural Gas plants in the state. It accounts for about 0.3% of Florida's operating Natural Gas capacity and 0.2% of all operating capacity in the state. Nationally it is the 611th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1956, it is older than 97% of the 108 operating Florida plants with a recorded commissioning year. Its operator, CITY OF LAKELAND - (FL), runs 3 operating plants in Florida totaling 1,193 MW. It shares Polk County with 13 other operating plants, including HINES ENERGY COMPLEX and POLK.
EIA-860 lists 4 generators at the site with 134 MW of nameplate capacity, mainly natural gas fired combined cycle technology (this page's HIFLD capacity figure is 149 MW). Net generation was 298 GWh in 2024 (a 25% capacity factor), up 58% from 2022. Its generators came online between 1956 and 1992.

Weather peril exposure
LARSEN MEMORIAL is a 149 MW natural gas power plant in Polk County, FL, operated by CITY OF LAKELAND - (FL), commissioned in 1956. Polk County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.4 of 5 at the 59th national percentile. Strong wind 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.
Polk County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Strong wind | Very High | 98th | 4.9 of 5 | 1.0 |
| Hurricane | Very High | 92nd | 4.7 of 5 | 0.25 |
| Wildfire | Relatively Moderate | 86th | 4.4 of 5 | <0.01 |
| Lightning | Very High | 59th | 3.4 of 5 | 95.7 |
| Tornado | Relatively High | 37th | 2.5 of 5 | 2.0 |
| Heat wave | Relatively Moderate | 21st | 1.8 of 5 | 3.2 |
| Riverine flooding | Relatively High | 17th | 1.7 of 5 | 1.4 |
| Hail | Relatively Moderate | 15th | 1.6 of 5 | 2.2 |
| Earthquake | Very Low | 9th | 1.3 of 5 | <0.01 |
Perils not assessed in Polk 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 |
|---|---|
| Coastal flooding | FEMA rating is "Not Applicable" for this county |
| Winter weather | FEMA rating is "No Rating" for this county |
| Ice storm | FEMA rating is "Not Applicable" for this county |
