MARKLAND, a 65 MW Hydro power plant in Switzerland County, Indiana. Operated by DUKE ENERGY INDIANA INC, commissioned 1967.
How MARKLAND compares
With 65 MW of capacity, MARKLAND ranks 43rd among the 77 operating power plants Bywatts maps in Indiana and is the largest of the 5 operating Hydro plants in the state. It accounts for about 70% of Indiana's operating Hydro capacity and 0.3% of all operating capacity in the state. Nationally it is the 245th-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1967, it is older than 79% of the 73 operating Indiana plants with a recorded commissioning year. Its operator, DUKE ENERGY INDIANA INC, runs 7 operating plants in Indiana totaling 5,601 MW.
EIA-860 lists 3 generators at the site with 78 MW of nameplate capacity, all conventional hydroelectric technology (this page's HIFLD capacity figure is 65 MW). Net generation was 299 GWh in 2024 (a 44% capacity factor), up 5% from 2022.

Weather peril exposure
MARKLAND is a 65 MW hydro power plant in Switzerland County, IN, operated by DUKE ENERGY INDIANA INC, commissioned in 1967. Switzerland County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.9 of 5 at the 22nd national percentile. Heat wave is the leading peril, rated Very Low by FEMA at the 89th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a hydro plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Switzerland County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Heat wave | Very Low | 89th | 4.6 of 5 | 6.4 |
| Tornado | Relatively Low | 87th | 4.5 of 5 | 0.15 |
| Strong wind | Relatively Moderate | 80th | 4.2 of 5 | 5.0 |
| Riverine flooding | Very Low | 70th | 3.8 of 5 | 1.7 |
| Earthquake | Very Low | 59th | 3.3 of 5 | <0.01 |
| Winter weather | Very Low | 54th | 3.2 of 5 | 10.4 |
| Ice storm | Relatively Low | 51st | 3.0 of 5 | 0.91 |
| Lightning | Very Low | 37th | 2.5 of 5 | 51.1 |
| Hail | Very Low | 24th | 2.0 of 5 | 3.6 |
| Hurricane | Very Low | 21st | 1.8 of 5 | <0.01 |
