Applying for permission to work in a protected zone

The permission of the line owner is always necessary when working in the protected zone of a power line. Uncoordinated forestry, excavation and transport work in the immediate vicinity of power lines endangers both the lives and health of workers. When planning these works, be sure to contact us in advance to determine if there is any overhead line, cable or substation owned by Elektrilev in the area.

Authorization to operate in the protection zone

An application must be submitted to co-ordinate the activities in the protection zone.In the case of an emergency works, attach a diagram or drawing to the application, indicating the area of work.

  • In case of planned works, the project or drawing must be coordinated in advance with Elektrilevi. Please attach the appropriate approval number and date to the application.
  • Unless the project coordination requires summoning a representative, no application for authorization to operate in the protection zone is required.
  • To coordinate oversized cargo, submit an application form to the Road Administration by e-mail.
  • Send the application at least 10 days before you start any work

    Coordination of activities

    If the planned work interferes with the protected zone of an overhead line, substation or other electrical installation, a representative of Elektrilevi shall explain the scope of the protection zone, applicable restrictions, safety requirements and responsibility for the maintenance of the electrical installation and issue a work permit.

    In the case of work in the protection zone of an overhead line, substation or other electrical installation, the contractor shall be responsible for maintaining the integrity of the electrical installation. The owner of the electrical installation has the right to claim reasonable expenses, if the execution of the works entails expenses for the maintenance of the electrical installation.

    If the works are carried out outside the protection zone, no permission from Elektrilevi is required.

    Scheduled works require that technical designs or drawings have prior approval from Elektrilevi. Unscheduled work requires a plan or a technical drawing with the precise work area attached to the application.

  • If the coordination of a project does not require indicating the location of the cables, our permission is also not necessary. If there is a power cable on the site or in the vicinity, someone from Elektrilevi will come and mark the location of the cables on the site and clarify the extent of the protected zone, the limitations in force, the safety requirements and your responsibility for making sure that the electrical system remains undamaged, and will then issue the permit for your work.
  • Digging work must not damage the electrical installation. The owner of the electrical system has the right to demand reasonable compensation for any expenses incurred.
  • If you have no cables on your property that belong to us, we still recommend specifying the location of your own or third party power cables before you start digging work; for example, when laying new water piping. To do that, you can ask us to locate the electrical cables on your property.Read more »
