Transporting and securing energy across Europe

8,802 km: that's the length of all the onshore and offshore power lines and cables managed by Elia Transmission in Belgium.  As the operator of the Belgian high-voltage grid, Elia keeps the lights on by matching electricity generation and consumption at all times.

Artificial energy island

Grid operator Elia has just started to work on one of the most challenging projects in its history: the Princess Elisabeth artificial energy island. It will be located in the middle of the 285km² Princess Elisabeth wind zone. This is the second offshore wind zone in the Belgian North Sea that has yet to be fully built. With a capacity of 3.5 gigawatts, the new wind farms will produce electricity equivalent to the annual consumption of 3.5 million households.

Catherine Vandenborre, CFO of Elia: “The Princess Elisabeth Island is a vital link in the successful energy transition in Belgium. The island has a dual function. First, it will bring electricity from the new offshore wind farms to the mainland. And then from 2030, the island will also be connected to wind farms in other countries with which electricity can be exchanged. This will give our country access to cheap and renewable energy.  This is crucial for our energy-intensive industries, which are rapidly moving away from fossil fuels and switching massively to wind energy over the next 10 years. In this way, Belgium is contributing to Europe’s climate goals and the ambition to realise 300 gigawatts of offshore wind in the North Sea by 2050.”

Designing for nature

In terms of location, design and implementation, due attention is being paid to limiting unwanted impacts on the marine environment. “We are going one step further and opting for nature-inclusive design,” explains Catherine Vandenborre. “In consultation with experts, we are taking concrete steps to protect the biodiversity around the island. For example, we are adding ledges to the outer storm walls where the kittiwake – a vulnerable bird species – can rest and breed. Below the waterline, several measures will be combined to create a diverse and rich artificial reef, with a particular focus on the return of the European flat oyster.  The measures have been selected on the basis of their technical feasibility and expected positive outcome.”

Co-creation and innovation

Achieving such a nature-inclusive design required close collaboration and knowledge sharing between all stakeholders and different domain experts. “An instructive process for all involved,” confirms Vandenborre. “With this initiative, Elia wants to set the tone for the environmentally friendly realisation of future offshore infrastructure. Europe’s seas are becoming the power stations of the future. By integrating biodiversity conservation measures from the design and construction phases, we want to increase and accelerate the positive outcomes. The co-creation project with the experts has already made an important contribution to scientific development in this field. But the work is not finished. Monitoring programmes will be put in place to follow up, and if necessary, adjust the selected measures.

Ready for the next gust of wind

As one of the main financial partners, BNP Paribas Fortis is supporting Elia’s transition to a reliable, affordable and environmentally friendly energy system. BNP Paribas Fortis has already financed 8 offshore wind projects in the Belgian North Sea. These 8 farms together represent 2200 megawatts, equivalent to 2 to 3 nuclear power plants. The next round? New wind farms in the Princess Elisabeth zone. This will be done through project financing, with the underlying contracts and resulting cash flows backing the loans.
