Old Harbour Diesel Power Plant: 347.5 MW Oil-Fired Facility in Jamaica

Old Harbour is an oil-fired diesel power plant located in Jamaica, operated by Jamaica Public Service Company. With a capacity of 347.5 MW, it is a significant contributor to the nation's power generation, supporting the grid's stability and meeting demand in the region. The plant operates on oil, a fuel source that aligns with Jamaica's energy mix, which includes both fossil fuels and renewable sources. As a diesel power plant, it uses internal combustion engines to generate electricity, a technology known for its flexibility and quick start-up capabilities. The facility is subject to Jamaica's national environmental regulations, which set emission limits for sulfur oxides, nitrogen oxides, and particulate matter. Old Harbour's operational status as an active plant underscores its importance in Jamaica's energy landscape. The plant serves the local community and industries, contributing to economic activity and energy security. Its location near the coast facilitates fuel delivery, while its capacity positions it as a medium-to-large scale facility within the Caribbean region.

The plant's oil-fired operation results in CO2, SOx, and NOx emissions, which are regulated under Jamaica's environmental laws. Its proximity to populated areas may raise local air quality concerns. The facility's age and technology (diesel engines) influence its efficiency and emission profile, with older units typically having higher emissions per MWh. The plant's capacity of 347.5 MW places it in a moderate scale band for the region.
