Air and Noise

E-REDES invests in the prevention, mitigation and control of noise and of greenhouse gases generated in the course of its activity.

Greenhouse Gases

In E-REDES activities, emissions or release of Greenhouse Gases (GHG) are mainly associated with:

  • Malfunctions or residual leaks of sulphur hexafluoride gas (SF6), used as a dielectric in electrical equipment.
  • Use of fossil fuels in the vehicle fleet;
  • Power losses in the distribution network.
  • Electricity consumption in administrative and technical buildings.

With a view to minimising these emissions, we have implemented a number of good practices, including:

  • Wherever possible, we seek to give priority to the selection of equipment that does not contain fluorinated gases or other substances that are dangerous to the environment.
  • We ensure equipment containing fluorinated gases (air conditioning, fixed fire protection systems, and switches containing SF6) is correctly maintained, repaired and leak detected, at the intervals defined in the applicable legislation in force.
  • We install power plants based on renewable generation technologies, intended solely for self-consumption in the buildings themselves, enabling a reduction in energy dependence and we issue energy certificates for our buildings;
  • We are committed to the gradual electrification of our fleet of light vehicles by replacing vehicles powered by internal combustion engines with electric vehicles.

Noise


The World Health Organization (WHO) considers that during the daytime, outdoor ambient noise should be below 55 dB near residential buildings. At night, to avoid sleep disturbance, ambient noise inside dwellings should not exceed 30 dB.

E-REDES infrastructures may produce disturbing noise for those living or staying in places where the effects of these noise sources are felt.

Based on the applicable legal requirements in force, we ensure the implementation of measures that prevent, control and minimise the noise emitted by our facilities.

In this sense, we have a set of recommendations for noise management and control, which are essentially reflected in the choice of the location of infrastructures and solutions in the design phase (acoustic insulation and construction of acoustic barriers).
