A roadmap addressing six priorities in circular economy

We are aware of our driving role to promote the circular economy. Our commitment is to become a leading company in the efficient use of resources by 2030. Therefore, we have established specific and measurable objectives in six priority areas.

Circular Economy Roadmap


With goals for 2025 and 2030

Raw materials

In order to reduce the consumption of raw materials and prioritise the use of recycled, recyclable or reusable products, it is necessary to make progress on issues related to establishing eco-friendly designs and the consideration of environmental impacts throughout the life cycle of equipment and materials. This progress will only be possible through collaborations with other key actors (mainly our suppliers) while promoting innovation and technological development.

In this regard, we developed a methodology for analysing the life cycle of supplies to assess aspects related to the circular economy, climate change, and water footprint, as well as to encourage the acquisition of more sustainable supplies.

Objectives for 2025

Ten supplies with the greatest impact on the transmission grid with circular criteria of climate change, security, diversity, and biodiversity.

100% eco-friendly packaging, recycled, recyclable or reusable packaging in the supply of equipment and materials.

Objectives for 2030

Creation of a network of circular supplies.

Identification of the environmental impacts of equipment and materials from their origin (LCA of supplies).

Integration of sustainability criteria in purchasing decisions.

Sustainable transformers (use of vegetable esters instead of mineral oils).

Innovation and technological development (eco-friendly designed equipment and materials).


Our goal is to produce zero waste (0% waste to landfills), and we are close to achieving it. In 2023, 98.4% of the total waste was recycled, regenerated, or used for energy recovery.

However, our waste generation is related to the number of construction and maintenance activities of the transmission grid carried out each year, so it is difficult to predict its evolution. Furthermore, the development of these activities is essential for the security of the electricity system or facilities and even to reduce environmental risks, which is why they cannot be limited. For this reason, the group’s objectives are mainly focused on completely reducing waste whose final destination is a landfill site, promoting alternative means of processing.

Objectives for 2025

0% of Red Eléctrica’s waste to landfill.

Definition of an action plan for zero waste to landfill in Redinter and Hispasat.

Implementation of the SF6 reuse procedure.

Reduction of hazardous land waste with the strategy of zero accidents and zero contaminated sites.

Objectives for 2030

0% waste to landfill.

100% SF6 waste reduction.

100% reduction of soil waste.

Zero Waste to Landfill Sites

Our subsidiary, Red Eléctrica, has had a zero waste to landfill model since 2018. Among the measures we have implemented thanks to this model, are the incorporation of recycling/waste-to-energy recovery requirements in tenders regarding waste management and the provision of services, the installation of composters for organic waste at work centres, and the launch of the awareness-raising campaign ‘We all deserve a second chance. From now on, waste becomes resources. Recycle, segregate, and be responsible.’ Since then, we have been working to replicate this model in the rest of Redeia’s companies and achieve our global goal of zero waste to landfills by 2030.

Waste generated by Red Eléctrica

Servicing/inspections, parts replacement, oil renewal, etc.

Improvement of facilities

Renewal of obsolete control gear, adaptation of accident prevention systems, etc.

Actions against accidents

The containment measures used in the case of leaks or spills and the associated cleaning work may lead to a large amount of waste.

Circular criteria and climate change in supplies

Find out about our actions to promote waste reduction among our suppliers the Supply Chain section.


Adequate equipment maintenance is carried out with strict procedures to reduce potential incidents. Furthermore, we have containment systems and emergency response protocols that allow us to respond promptly to accidental spills.

At Red Eléctrica substations, we have measures to reduce, control, or completely eliminate identified potential risks. It is worth mentioning:

  • Soil and groundwater characterisation.
  • Intensification of inspections at high-risk facilities.
  • Blue Filtering Project: installation of hydrocarbon separator filters at the outlet of oil collection tanks.
  • Definition of an internal procedure for the removal of insulating fluid from out-of-service fibre optic cables.
Objectives for 2025

Zero serious environmental accidents at the facilities.

Zero contaminated sites.

Identification of alternatives to plant protection products.

Objectives for 2030

Action plan for the prevention of hydrocarbon leaks and mitigation of their impacts.

Decontamination of 100% of soils affected by accidental hydrocarbon spills.

100% reduction in the use of phytosanitary products in sub-stations.

Sustainable treatment methods for soils and groundwater affected by dielectric oils or hydrocarbons.

We work on finding innovative and sustainable solutions for on-site clean-up of these contaminants, employing alternative procedures for excavation and disposal that help reduce the volume of waste generated to avoid sending contaminated soil to landfills. Among the techniques tested is bioremediation—identifying microbial consortiums capable of degrading substances used by Red Eléctrica—as well as the application of surfactants and chemical oxidation.


Our water consumption is very low, limited to domestic activities such as toilet facilities, non-industrial building cleaning, and garden irrigation, and is not currently considered a material issue for Redeia. However, we work to find alternative solutions to improve efficiency and optimise the use of this resource to achieve our reduction targets.

Objectives for 2025

Reduction of water consumption in all work centres of Red Eléctrica and Redinter to 6.5 m³/employee/year.

100% of the water from the Salto de Chira construction process to be reused.

Objectives for 2030

Reduction of water consumption in all workplaces to 6.5 m³/employee/year.

Supply chain

Our suppliers are directly involved in our activities. Therefore, our contribution to sustainable development is closely linked to the selection and management of our suppliers. In this regard, we have identified potential criteria and requirements related to circularity and climate change to be included in our tenders. We have also developed our methodology for life cycle analysis (LCA) and prepared a matrix for assessing the LCA of supplies for their inclusion in future purchasing processes.

Furthermore, we reuse equipment and materials to the extent possible when they reach the end of their useful lives.

Objectives for 2025

Analysing at least ten supplies with a major impact on the transmission grid with circularity criteria (LCA – Life Cycle Assessment), climate change, security, diversity, and biodiversity.

Objectives for 2030

Be a driver of change for our suppliers: at least 25 supplies with a major impact on the transmission grid with circularity criteria (LCA – Life Cycle Assessment), climate change, security, diversity, and biodiversity.
