Stony Brook534.6 MW Oil

Oil

The Stony Brook 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 534.6 MW. Its primary operation relies on harnessing oil energy resources to generate bulk electricity. To ensure flexibility and reliability, the station is also configured to utilize gas as an auxiliary or secondary fuel source. Operational management and ownership of the facility are handled by the Massachusetts Mun Wholes Electric Co, which oversees daily maintenance and grid dispatch integration. The facility was officially connected to the commercial grid in 1981, 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, Stony Brook occupies the #18 position among all operational oil power plants. Its 534.6 MW capacity represents a 1.38% share of United States of America's total installed oil generating capacity, which currently stands at 38,602 MW. The largest operational oil installation in United States of America is the Manatee with an output of 2,951 MW, making the Stony Brook approximately 5.5 times smaller by comparison. Across all fuel types and electricity generation technologies country-wide, this facility accounts for 0.0386% of United States of America's aggregate generation capacity of 1,386,385 MW. Based on historical capacity factors characteristic of oil power plants (modeled at 15% for analysis), the facility's expected annual electricity generation is calculated at approximately 702,464 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 63,860 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 42.1978° latitude and -72.5106° longitude. Analysis of local grid infrastructure shows a density of other assets within a 50-kilometer radius. These nearby facilities include Northfield Mountain (hydro, 1,168 MW), Berkshire Power (gas, 289 MW), Masspower (gas, 260.9 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.

An Overview of Oil as a Power Generation Energy Source

Oil has been a significant source of energy for power generation worldwide, with 2,416 oil power plants distributed across 108 countries, contributing a total installed capacity of approximately 286.9 gigawatts (GW). The reliance on oil for electricity generation has its roots in the ease of extraction, transportation, and the energy density of crude oil, making it a practical choice for many nations. Notable countries that utilise oil in power generation include Japan, Saudi Arabia, the United States, Iran, and Mexico, with Japan hosting 29 plants and leading in capacity at 49.9 GW, closely followed by Saudi Arabia with 53 plants at 49.7 GW. The United States has 883 oil power plants with a combined capacity of 39.4 GW, while Iran and Mexico have 22 and 23 plants, respectively, with capacities of 13.5 GW and 12.2 GW.
