Currently SEDISA operates a number of energy production facilities owned by others, taking care of both the functional aspect (operation and maintenance) and the administrative and legal.

SEDISA performs feasibility studies in industrial facilities to implement energy saving processes based on the use of alternative fuels, the introduction of more efficient systems or changes on the habits of production.

SEDISA, designs and erects any type of industrial installation, from the stage of pre-feasibility study to commissioning.

SEDlSA conducts environmental studies and the necessary procedures for obtaining Integrated Environmental Authorizations(IPPC).
