A Zero-Emissions Future

We strive to reduce emissions associated with our activities as part of our commitment to combating climate change.

Steady Progress and Clear Objectives

We set medium-term targets that set the necessary rhythm to achieve our objective. Until then, we fully offset all our scope 1 emissions.

Para 2030 (vs 2019):
  • 55% reduction in scope 1 and 2 emissions.
  • 28% reduction in scope 3 emissions.
Para 2050 (vs 2019):
  • 90% reduction in scope 1 and 2 emissions.
  • 90% reduction in scope 3 emissions.

Logo Science Based Targets

Our emission reduction targets for 2030 and the net-zero target for 2050 have been approved by the SBTi initiative.

We have tools and an objective methodology

We draw up our greenhouse gas emission inventory based on the GHG Protocol methodology, independently audited under ISAE 3410.

Our unique methodology calculates the carbon footprint associated with the life cycle of our assets to identify specific improvement and reduction measures.

Control of SF6 Emissions

Sulphur hexafluoride (SF6) is the primary direct emission from our activity, as it is produced by the equipment used in electricity transmission.

Using SF6 strategically enables us to reduce the spacing between different elements in our sites, facilitating a reduction in size and, consequently, minimising our environmental impact.

Goals
  • -25% reduction in net emissions by 2030(vs 2015).
  • Maximum 252 kt CO2 eq. in the 2021-2030 period.
Actions
  • Improvement of leak control and registration procedures.
  • Training for gas handling. Training for gas handling.
  • Progressive renewal of old equipment.
  • Prevention, early detection, and improvement of leak repair procedures.
  • Reduction of installed gas. Projects to advance and promote alternatives to SF6.
Losses in the Transmission Grid

We strive to enhance aspects within our control that can impact the reduction of emissions associated with losses in the transmission grid.

The transmission of electric energy inevitably results in energy losses in the grid due to multiple factors, with the most significant one being the Joule effect associated with current flow through conductors.

These emissions primarily depend on the structure of power generation and transmission grid flows, which are beyond the company's control. The reason for this is that the system operation must comply with mandatory procedures and rules of the electricity market regulated by an independent entity.

Increasing losses are an unavoidable consequence of the transition of the electric system towards a more decarbonised and flexible one, with a higher reliance on renewable sources (further away from consumption points), international flows, and demand (greater electrification).

Emissions related to energy losses in the transmission grid are accounted for within scope 2 emissions, as indicated by the GHG Protocol. They are calculated considering the energy dissipated in the grid (losses) and the emission factor of the energy mix, which we calculate based on the quantity of energy generated by different technologies.

However, concerning the emission factor, our determination to integrate more renewable energy into the energy mix results in a progressively lower emission factor and, consequently, a net reduction in emissions associated with losses.

Eficiency
Goals

Energy efficiency is a primary tool in our commitment to combating climate change.

Therefore, we apply it at all levels through several projects and measures:

Buildings
  • Energy management system certified under ISO 50001:2018 at Redeia's headquarters and campus.
  • Reduced energy consumption through geothermal energy exploitation and construction measures in line with Nearly Zero Energy Buildings (NZEB) criteria, both in our Control Centre and Elewit's headquarters, which also has photovoltaic systems for self
  • Efficiency measures in buildings with an estimated associated savings exceeding 1,700,000 kWh in the 2021-2030 period. For example, efficient LED lighting or standby systems in equipment, among other aspects.
  • Salto de Chira pumped storage hydroelectric power station, whose design is based on criteria of the LEED Platinum certification by the US Building Council.
IT Systems
  • Renewal of IT equipment and systems according to criteria of maximum efficiency.
  • Policies for efficient use of the office equipment.
  • Collaborative communication platforms to minimise travel.
  • Intensive use of virtual servers.
Substations

Rationalisation in the use of lighting. Thanks to improvements in remote control systems for exterior lighting, there are currently 426 substations where night-time lighting remains off throughout the night, functioning only in emergencies.

Goals
  • 10% reduction in electricity consumption by 2025 (compared to 2019).
  • 100% renewable electricity contracted by 2024.
  • Implementation of self-consumption installations in 21 workplaces.
Offsetting

We commit to offsetting all our direct emissions that cannot be reduced from 2023 onwards to minimise the group's carbon footprint.

One of the primary offsetting projects is the Redeia Forest.

Objective
  • 100 % offsetting of scope 1 emissions.
Supply chain

Every link in the value chain is involved in our commitment, from our staff to suppliers and customers.

Moreover, several initiatives have been launched to reduce emissions associated with our supply chain. Among these initiatives, we highlight our Carbon Footprint Reduction Collaboration Programme, established in 2019, where we collaborate with our key suppliers:

Goals
  • 28% reduction in scope 3 emissions compared to 2019. 90% reduction by 2050.
  • Making suppliers responsible for 2/3 of emissions with SBTi by 2026.
