This project entails dismantling the 70 kV high-voltage overhead line between Jemeppe-sur-Sambre and the Gembloux substation and replacing it with a 150 kV high-voltage line.
An investment for the future
Elia plans to dismantle the single 70 kV power line between the Auvelais substation (located at Jemeppe-sur-Sambre) and the Gembloux substation and replace it with a new dual 150 kV power line.
Built in 1938, the current connection is nearing the end of its life and will not be able to meet the region's future electricity needs.
Benefits to society
We identified three needs:
- ensure the safety and security of people and infrastructure;
- enhance grid reliability;
- enable the integration of renewable energies.
To meet these three challenges, Elia plans to:
- lay a dual 150 kV underground line;
- dismantle the existing line;
- switch from a single 70 kV to a dual 150 kV connection.
Elia plans to invest €10 million in this infrastructure project. This investment is included in the 2015-2025 Federal Development Plan and has been approved by the Minister of Energy.
Elia's investment policy must be pursued with due diligence, meaning that every euro spent must be authorised by one or more government(s) as part of a federal and/or regional plan and invested wisely.
This philosophy underpins the entire project.
As a socially responsible company, Elia is deeply committed to the environment. It contributes actively to the energy transition and is particularly concerned with preserving biodiversity. It also works closely with local authorities, residents and all the local stakeholders affected by its infrastructure projects as it expands and upgrades its grid.
An environmental impact assessment (EIA) was carried out by an independent consultancy.
During the works phase, Elia also makes every effort to minimise the impact of its infrastructure projects on the local environment in which they are located.
The first three-phase transmission line (circuit) will be live by September 2022. It will allow the current overhead line to be dismantled: the conductors will be dismantled at the end of 2022, whilst the pylons and their foundations will be dismantled at the beginning of 2023.

Dismantling of the old 70 kV connection
After 18 months of work, the installation of the new 150 kV underground connection between the Auvelais and Gembloux substations has been completed. It was successfully energised on 20 September. Now that security of supply is guaranteed, the dismantling of the old overhead line can begin in early October.
