The power business is integrated with the natural gas activity through use of its cogeneration plants and through its marketing activity. Galp aims to maintain a competitive electricity generation and marketing portfolio.

Through its cogeneration portfolio, Galp currently has an installed capacity of 173 MW in Portugal.

Galp also has a presence in the electricity market through Mercado Ibérico de Electricidade – (MIBEL), both in the spot market (OMEL) and in the futures market (OMIP). The primary objective of this activity is the acquisition of electricity in the market, which is sold through the marketing activity.


What is 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) most of the energy contained in the fuel is transformed into heat and lost to the environment.

Galp's cogenerations units

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 a major source of natural gas consumption, as well as an important source of energy for operating the 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 Galp's only source of electricity generation subject to special regime production, ie. with priority access to the grid, and sold at a regulated tariff.

  Installed capacity (MW) Sales of electricity to the grid (GWh) Natural gas consumption (mm³)
Sines 82 656 232
Matosinhos 82 694 251
Others 9 37 0
Total 173 1,386 483

Renewable energy

Galp has a 50% stake in a project with 12 MW of installed capacity in a wind farm in Portugal, which came on stream in 2011, producing over 30 GWh in 2018.

As the renewable energy industry develops, its competitiveness with fossil fuels has increased over time.

Galp's renewable energy activities

Galp aims to be an active partner in changing the energy paradigm by:

  • Anticipating trends.
  • Making its portfolio adequate to future needs.
  • Creating synergies simultaneously with current activities.
  • Consolidating Galps know-how.
  • Enhancing asset diversification, namely in lower carbon intensity energy.
