Saint Marys Hospital Power Plant15.4 MW Natural Gas

Gas

The Saint Marys Hospital Power Plant is a key infrastructure asset in United States of America's power generation grid, located on the continent of North America. Designated as a fossil fuel electricity generation station, the facility features an installed capacity of 15.4 MW. Its primary operation relies on harnessing gas energy resources to generate bulk electricity. To ensure flexibility and reliability, the station is also configured to utilize oil as an auxiliary or secondary fuel source. Operational management and ownership of the facility are handled by the St Mary's Hospital, which oversees daily maintenance and grid dispatch integration. The facility was officially connected to the commercial grid in 1989, since which it has maintained regular output, playing a structured role in domestic power supply security. In terms of domestic production capacity within United States of America, Saint Marys Hospital Power Plant occupies the #1420 position among all operational gas power plants. Its 15.4 MW capacity represents a 0.00% share of United States of America's total installed gas generating capacity, which currently stands at 592,647 MW. The largest operational gas installation in United States of America is the West County Energy Center with an output of 4,263 MW, making the Saint Marys Hospital Power Plant approximately 276.8 times smaller by comparison. Across all fuel types and electricity generation technologies country-wide, this facility accounts for 0.0011% of United States of America's aggregate generation capacity of 1,386,385 MW. Based on historical capacity factors characteristic of gas power plants (modeled at 40% for analysis), the facility's expected annual electricity generation is calculated at approximately 53,962 MWh. Applying domestic consumption statistics where an average household in United States of America consumes 11 MWh of electricity annually, this level of production is sufficient to meet the energy demands of roughly 4,906 homes. By utilizing traditional thermal power processes, the station delivers reliable dispatchable energy to the grid, supporting grid resilience during periods of low renewable resource availability and satisfying industrial base-load demands. The physical site of the station is located at geographic coordinates 44.0979° latitude and -92.4798° longitude. Analysis of local grid infrastructure shows a density of other assets within a 50-kilometer radius. These nearby facilities include Pleasant Valley (MN) (gas, 467.8 MW), Cannon Falls Energy Center (gas, 346.8 MW), Pleasant Valley Wind Farm (wind, 200 MW), representing a cluster of localized power assets. This geographic placement is vital for reinforcing regional distribution infrastructure and minimizing transmission line losses across this sector of United States of America.
