Double benefits for the wind energy sector

BIL provides developers and operators of wind power plants with a central enquiry portal for planning enquiries.


Since February 2016, nearly 900,000 planning enquiries from more than 50,000 users have been processed successfully using the BIL portal. The cooperatively organised operator community of BIL eG unites all sectors of the supply line infrastructure across all industries.

Wind turbine operators can significantly increase their operational reliability by participating in the BIL process. Since the generation and feed-in points are often located at a great distance from each other, it is particularly important for operators to be clearly identified in order to avoid damage to the underground infrastructure. Lesser-known operators in particular benefit from using the BIL construction enquiry portal, which is free of charge to enquirers, because it gives them a better overview of planned construction and planning activities in their cable area. 

Inquirers receive a real-time list of responsible and non-responsible operators as a result of the BIL process when they submit an online enquiry. Automated verification of responsibility using the operator's own data identifies the operators who are actually responsible. Non-relevant construction requests do not reach the operator in the first place, resulting in significant savings in processing time. Even for small grid operators, the significant reduction of so-called zero notices is sufficient to finance the contribution to the BIL process.

BIL offers a contribution model specifically tailored to the wind power industry. As a cooperative initiative of grid and line operators from all sectors, BIL provides the first online construction enquiry portal in Germany that is free of charge for the enquirer. The common goal is to increase the safety of underground infrastructure by establishing a "single point of entry" for construction enquiries. Currently, more than 130 companies are using the BIL portal to optimize their own planning enquiries process. BIL eG is supported by eight industry associations.
