Emissions

Atmospheric emissions

The main environmental impacts resulting from the combustion of fossil fuels in thermoelectric power plants consists of atmospheric emissions.

Regarding CO2 emissions, EDP is at the forefront of the Energy Transition and, therefore, we are promoting the decarbonisation of our production. By 2030, we intend to reduce 90% of CO2 emissions, compared to 2005.

Moreover, EDP has been investing in monitoring and minimizing such impacts, in particular through desulphuration and denitrification processes in coal thermoelectric plants.

Gaseous effluents produced by EDP facilities are controlled by permanently monitoring and regularly measuring minority pollutants such as heavy metals and volatile organic compounds.

Currently, the coal thermoelectric plants within theIberian Peninsula have SO2 and NOx emission reduction systems.

 
 
 
 

Wastewater

EDP’s thermoelectric plants have wastewater treatment facilities in order to ensure the quality of the water that is released into the water environment.

 

The EDP Group regularly monitors the quality of effluents, under the provisions set out in the respective environmental permits and current legislation.

In the case of Soto Ribera effluents are discharged into the Nalón river, which has been declared a Community Interest Site. Its effluents are subject to temperature conditions and physical-chemical parameters which ensure that the receiving medium is not affected.

The thermal impact of cooling water from EDP’s thermoelectric plants is periodically monitored according to the specific features of each plant and their respective environmental permits. Aerial thermography and other measurements allow us to verify our compliance with established temperature limits.

Noise

EDP conducts noise measurements in order to verify compliance with current legislation.

Within the framework of Distribution activities, there has been an increasing attention to soundscape assessment and quality control measures, since facilities are often located in close proximity to residential areas.

EDP has been implementing sound insulation measures in the construction of new infrastructure.

Electromagnetic fields

Electromagnetic fields are present everywhere in our environment, naturally on the planet and in the natural physiology of the human body, and wherever electricity is generated, transmitted, distributed or used.

 

When used properly, electromagnetic fields contribute to the improvement of our quality of life, health and well-being. However, above certain levels, these fields can be harmful to health and affect the human body in different ways depending on their frequency. Thus, there are standards for limiting exposure to electromagnetic fields, both for specific frequencies and applications and for the entire electromagnetic field spectrum.

 

In addition to full compliance with applicable legislation and regulations, EDP systematically follows the development of national and international scientific studies and adopts the recommendations of world reference entities, especially the World Health Organization (WHO).
