Dual benefits for the wind energy sector

BIL information on pipeline and cable routes - greater feed-in security for wind farm operators.
The national information system on buried infrastructure offers dual benefits for the wind energy sector.


BIL, the national information system for buried infrastructure, is a central planning enquiry portal for building contractors and operators of wind turbines. Over half a million planning enquiries of more than 35,000 users have been processed successfully using the BIL portal since February 2016.

By participating in the BIL process, wind turbine operators can significantly increase their grid feed-in security. As the distances between the generation point and the grid feed-in point are often quite long, it is particularly important for building contractors to identify the operators of buried energy and telecommunication infrastructure to avoid damaging existing pipelines and cables. Unknown operators in particular benefit from the volume of enquiries from pipeline companies and receive an improved overview of the construction measures planned within the area in which their own pipelines and cables are installed.

The BIL process provides users with a positive/negative list in real time in response to their online request. The automated check identifies the operators who are actually responsible for buried infrastructure in a certain area. Non-relevant enquiries are not forwarded to the pipeline or cable route operator, which saves a considerable amount of processing time. A significant reduction of so-called non-responsibilities is sufficient for even small network operators to cover their BIL fee. BIL offers a bespoke fee model aimed specifically at the wind energy sector.

For the first time in Germany, a cooperative initiative of pipeline and cable route operators from all sectors, known as BIL, is providing a free online planning enquiry portal. Their objective is to increase the security of pipeline and cable networks by establishing a single point of contact for all planning enquiries. There are currently over one hundred companies participating in the BIL portal.
