Cogeneration

Cogeneration consists of the simultaneous production of thermal energy (heat) and mechanical energy (electricity), from a single fuel. It relies on the local recovery of residual heat generated in the power generation thermodynamic processes that would otherwise be wasted. In conventional processes that transform fossil energy into electricity (thermoelectric power plants)

Galp's installed capacity for electricity generation through cogeneration totals 173 MW, with the main cogeneration units installed in the Sines and Matosinhos refineries.

These are highly efficient combined heat and power generation plants that are an important steam supplier to our refineries.

The cogeneration plants at the Sines and Matosinhos refineries are the largest in the country, which position Galp as the top user of cogeneration technology in Portugal.

Currently, these plants are subject to special regime production, i.e. with priority access to the grid, and sold at a regulated tariff.

  Installed capacity (MW) Sales of electricity to the grid (GWh) Thermal energy produced (GWh) Natural gas consumption (mm³)

Matosinhos 82 672 1,412 244
Others 9 37 45 8
Total 173 1,325 2,867 480
