Cogeneration

Galp's power activity is supported by the operation of cogeneration units in Portugal totalling 91 MW, with the main unit installed in the Sines refinery. This unit is highly efficient, as it combines heat and electricity generation, and it is a significant supplier of steam to the refinery operations.

Following the decision to discontinue the Matosinhos refining operations from 2021 onwards, Galp halted cogeneration operations in Matosinhos as of October 2021.

In 2021, cogeneration units produced approximately 980 GWh, down 28% YoY, reflecting the lower contribution from the Matosinhos cogeneration.

 

About 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)
