R D MORROW, a 400 MW Coal power plant in Lamar County, Mississippi. Operated by SOUTH MISSISSIPPI EL PWR ASSN, commissioned 2023.
How R D MORROW compares
With 400 MW of capacity, R D MORROW ranks 15th among the 37 operating power plants Bywatts maps in Mississippi and is the smallest of the 4 operating Coal plants in the state. It accounts for about 9.2% of Mississippi's operating Coal capacity and 2.6% of all operating capacity in the state. Nationally it is the 175th-largest of the 324 operating Coal plants in the database. Commissioned in 2023, it is newer than 97% of the 35 operating Mississippi plants with a recorded commissioning year. Its operator, SOUTH MISSISSIPPI EL PWR ASSN, runs 6 operating plants in Mississippi totaling 2,209 MW.
Under the same EIA plant code, EIA-860 lists 2 generators at the site with 558 MW of nameplate capacity (this page's HIFLD capacity figure is 400 MW). Net generation was 2,678 GWh in 2024 (a 55% capacity factor).
Grid neighborhood
The closest transmission line found within 10 miles is a 161 kV line owned by MISSISSIPPI POWER CO, under 0.1 miles away. Another 2 operating power plants totaling 561 MW sit within 25 miles; the largest is MOSELLE (511 MW, Natural Gas).

Weather peril exposure
R D MORROW is a 400 MW coal power plant in Lamar County, MS, operated by SOUTH MISSISSIPPI EL PWR ASSN, commissioned in 2023. Lamar County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.2 of 5 at the 55th national percentile. Hurricane is the leading peril, rated Relatively Moderate by FEMA at the 88th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a coal plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
