The project calls for the evaluation by dispersion modeling of a capacity expansion by 144 MW of the Delimara Thermal Power Station on Malta in terms of the resulting increase in ambient level of air pollution, increase over the baseline, and compliance with the air quality standards defined by the Air Quality Framework Directive (2008/50/EC), and (2004/107/EC).

The Delimara power station is located at the South-Eastern end of Malta's main island, the Delimara peninsula inside Marsaxlokk bay, and was originally commissioned in 1992. With its stack of 150 m, it also boasts the highest built structure on Malta.

Plant components:

• two steam units with boiler (burning heavy fuel oil, HFO), steam turbine and generator, for baseload operations, 2 * 60 MW..
• two open cycle gas turbines (burning gasoil) and generator units at 37.5 MW, designed for peak load.
• two combined cycle gas turbines (gasoil) with heat recovery steam generators and a steam turbine for midrange duties, total capacity of 110 MW.

The total installed capcity (baseline scenario) amounts to 305 MW.
The assocaited fuel storage has capacities of 55,500 m3 (HFO) and 26,800 m3 gas oil.
