Reinforcing the connection between France and Belgium : RTE and Elia enter the final phase of work on the Avelin-Avelgem link

Source: RTE 14/10/2005

RTE and Elia have entered the final phase of work in October and November to reinforce the interconnector Avelin?Avelgem, in order to see the new line operational by the end of November 2005.

Bang on schedule, the French and Belgian transmission system operators RTE and Elia have entered the final phase of work being done in October and November to reinforce the existing 400,000-volt line between Avelin in France and Avelgem in Belgium. Their objective is to see the new line operational by the end of November 2005.

The very-high-voltage link (400,000 V) between the Avelin substation to the south of Lille and the Avelgem substation in Belgium is a main European transit channel. Built back in 1974, it only had a single circuit, but was configured from the outset to accommodate a second.

To increase the two countries' power exchange capacity, and to boost the level of mutual aid between the French and Belgian systems, early in 2003 RTE and Elia decided both to strengthen the link between them by fitting the existing line with a second circuit and to carry out additional work aimed at preventing congestion either upstream or downstream that would hinder the full usage of the ensuing capacity increase.

Instead of simply doubling the line, RTE opted to create a direct link between the Avelgem substation and the Mastaing substation located further inside the French system (half-way between Valenciennes and Cambrai). Once the work has been finished, the cross-border link will comprise one direct circuit between Avelgem and Avelin and another circuit between Avelgem and Mastaing, passing close by Avelin.

RTE and Elia will complete the connection in October and November with a view to bringing the line on stream in late November.

All this work will necessitate the scheduled outage of the existing Avelgem-Avelin circuit, so during the period in question only the new circuit will be operational.
