Santa Cruz Diesel Power Plant, Cuba - 300 MW Oil-Fired Facility

Santa Cruz is a diesel power plant located in Cuba, with a capacity of 300 MW. It is operated by Unión Eléctrica, the state-owned electric utility, and plays a key role in the country's power generation mix. The plant uses oil as its primary fuel, reflecting Cuba's reliance on fossil fuels for electricity generation. Cuba's power sector is dominated by aging thermal plants, and Santa Cruz is among the larger facilities. The plant operates under national environmental regulations, which are less stringent than international standards like the EU Industrial Emissions Directive. Diesel and oil-fired plants typically have higher CO2, SOx, and NOx emissions per MWh compared to natural gas or renewable sources. The plant's location near the northern coast may influence local air quality and marine ecosystems. As a dispatchable power source, Santa Cruz supports grid stability, especially during peak demand. However, its age and fuel type contribute to a significant environmental footprint, aligning with Cuba's broader energy challenges.

The plant's use of oil as fuel results in substantial CO2, SOx, and NOx emissions, contributing to local air pollution and greenhouse gas emissions. Its proximity to populated areas and the coast may affect community health and marine ecosystems. Cuba's regulatory framework for emissions is less developed than in the EU or US, meaning older plants like Santa Cruz may operate with limited pollution controls.
