Dual benefits for the wind energy sector

BIL infrastructure enquiry - greater operation reliability for wind park operators.
The national information system for underground infrastructure offers dual benefits for the wind energy sector.


BIL, the national information system for underground 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 Feb 2016.

By participating in the BIL process, wind turbine operators can significantly increase their operation reliability. 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 underground energy and telecommunication infrastructure to avoid damaging existing supply cables. Unknown operators in particular benefit from the volume of enquiries from the well-known pipeline operators 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 underground infrastructure in a certain area. Non-relevant enquiries are not forwarded to the pipeline or network 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 network 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, which is supported by eight industry associations.
