The Stevin project aims to upgrade the electricity grid between Zomergem and Zeebrugge

A robust grid for transmitting electricity inland

The Stevin project is designed to shore up the high-voltage grid between Zomergem and Zeebrugge. It sets out to upgrade the existing high-voltage grid in West and East Flanders so that more electricity can be brought inland from the coast. Elia is also installing new overhead and underground connections and dismantling 53 km of old lines, which will be replaced by 35 km of underground cables once the new connections are operational.

  • texteIn the interest of society

    The Stevin project offers a response to four key challenges facing our electricity grid:

    • It will make it possible to bring wind power from offshore wind farms to the mainland and transport it throughout the country.
    • This extension of the 380 kV grid will substantially improve the electricity supply in West Flanders and facilitate further economic development in the strategically important growth area in and around the port of Zeebrugge.
    • It will enable additional decentralised power generation units in the coastal region (wind and solar power, and other forms of sustainable energy) to be connected to the grid.
  • texteThe route

    The Stevin project covers a distance of 47 km and crosses eight municipalities in West and East Flanders. Most of the route runs through farmland. The project to upgrade the high-voltage grid between Zomergem and Zeebrugge consists of ten sub-projects. The first eight have to do with the construction of the Stevin route, while the final two involve dismantling the two existing high-voltage lines, which will ultimately become redundant.

  • environnementEnvironment
    • Elia is implementing a series of measures to minimise the impact of its work on the local area.
    • The project’s contractors are using low-noise technologies and do all their work between 7.00 a.m. and 7.00 p.m., only deviating from this schedule in exceptional circumstances and emergencies.
    • Elia strives to ensure that local residents always have easy access to their homes. However, if access routes do need to be closed temporarily, homeowners are notified in good time and, where possible, we set up a diversion.
    • If additional measures are required, such as changes to driving routes or the closure of a road to traffic in one direction, we always discuss these with the local police well in advance.
    • The project website (only available in Dutch) is a valuable source of information while work is ongoing. Letters to local residents and the digital newsletter also provide up-to-date information about the status of the work. You can sign up for the digital newsletter at
