ASSEMINI Diesel Power Plant, Assemini, Italy | 177 MW Oil-Fired Facility

ASSEMINI is a diesel power plant located in Assemini, Italy, with a capacity of 177 megawatts (MW). It is owned by the Italy Ministry of Economy and Finance and is currently operational. The plant uses oil as its primary fuel, placing it within the medium-scale range for diesel power generation in Italy. The plant operates under the European Union's Industrial Emissions Directive (2010/75/EU), which sets strict emission limits for large combustion plants. Best Available Techniques (BAT) conclusions for large combustion plants apply, requiring efficient combustion and pollution control measures. Diesel plants typically have higher CO2 emissions per MWh compared to natural gas, and oil combustion also produces SOx and NOx, which are regulated under the directive. As a diesel plant, ASSEMINI contributes to grid stability and peak load support in the Sardinia region. Its proximity to populated areas may require careful management of local air quality. The plant's role in the Italian energy mix is part of a broader transition toward renewable energy sources, though diesel plants remain important for backup and balancing.

The plant's oil fuel source results in significant CO2, SOx, and NOx emissions compared to natural gas or renewables. Its location near populated areas in Sardinia may raise local air quality concerns, regulated under EU ambient air quality standards. The 177 MW capacity places it in a medium-scale category, with environmental impact proportional to its output and fuel type.
