Evolution of power generation installed base: highlights

In 2017, several changes to the installed base occurred

  • the open cycles at Angleur 3 (two times 25 MW) and Izegem (20 MW) were put back on the market; the decision to postpone their final shutdown by two years was communicated to the authorities on April 12, 2017;
  • the Ghent-Ham combined cycle plant (52 MW) was permanently shut down on November 1st, 2017;
  • the installed power of the wind parc grew by 25% (376 MW), with 161 wind turbines in operation at the end of 2017.

Some of these changes will contribute to the decrease in the carbon footprint from the company’s electricity production (see Scope 1).

The Seraing plant chosen for the 2017-2018 strategic reserve

By the Royal Decree of 31 October 2017, the gas-combined cycle of Seraing was chosen for the strategic reserve for the 2017-2018 winter. This plant, with a 470 MW capacity, employs around 30 people.


The Seraing plant was again placed in the strategic reserve, from 1 November 2017 through 31 March 2018, within the context of an annual contract ending on 31 October 2018.


This plant was required to be ready to start up at any time at the instruction of Elia, in order to contribute to the country’s electricity supply security. This plant demonstrated excellent reliability and succeeded at all of the surprise startup tests required by Elia in 2017.


The Seraing gas-steam plant is able to provide black-start capacity services. They allow the unit to start up, at any time of the year, without any external electricity feed, and to progressively resupply the network users in the event of a blackout.

Closure of a gas-steam turbine at the Ghent-Ham site

After 23 years of operation, the 52 MW gas-steam turbine at Ghent-Ham was permanently shut down on October 31 2017. The authorities had been notified of this shutdown in July 2016.


The Ghent-Ham plant was not selected for the strategic reserve for the winters of 2016-2017 and 2017-2018. The revenues generated by market demand were not sufficient to cover the fixed operating costs.


EDF Luminus continues to invest in the district heating network that feeds the city of Ghent.

This heating network is fed by the two next-generation 2.7 MW cogeneration units at the Ghent-Ham plant.


In 2017, the EDF Luminus investment committee decided to install a new, 5 MW cogeneration unit, to secure the feeding of power to Ghent’s district heating network.
