Estimated end date of the dismantling




In defining the dismantling works, environmental measures and safety procedures have been considered a priority to ensure they are carried out correctly and that third parties and the environment are not affected.

The buildings and installations at the power plants feature different types and combinations of structural elements. Therefore, a combination of manual and mechanical procedures have been incorporated into the dismantling and demolition methodology, in some cases combining the two types of procedures and using explosives to carry out controlled blasting.

Dismantling tasks carried out

The dismantling tasks carried out to date are: 

  • The tasks of cleaning and removing explosive atmospheres from deposits and circuits. 

  • The electrical systems (including the power transformers), the main equipment (turbine, alternator, mills, fans, etc.) and a large part of the interconnection pipes between the boiler and the turbine have been dismantled, having previously had their thermal insulation removed.

Local hiring

There are around 90 people on site working on these tasks, of which the following are locally hired:

  • 9 people from the Just Transition Institute list (seven of them residents in Cerceda, Ordes or Carral).

  • 17 people from Cerceda, Ordes and Carral.

  • 45 people from other municipalities in the province.

  • Occasional participation of local companies


The fact that most of the plot is a “flood zone” will make it difficult to develop future industrial activities and using the existing diversion dam and other riverbank installations has been ruled out as this use is incompatible with restoring the riverbed. Possible solution to protect the plot are under analysis taking into account CHC criteria.

Third-party use of ash deposited in the plant’s non-hazardous waste landfill is under study and town refurbishment may be an opportunity for new activities.
