OutSmart and installation responsibility

The question of how to organize the electrical installation responsibility arises at every wind and solar farm. Organising this responsibility can be complex, especially for larger wind and solar farms that also have their own electrical infrastructure and substation.

Rules and regulation

Starting point from legislation and regulations: It must be ensured that there is always only one person responsible for an electrical installation.

Different countries in Europe have different laws governing the safety of employees. Within Europe, EN 50110 is used as the standard for working safely on high and low voltage installations. This standard states which practical agreements and which methods and working procedures must be applied.

In the Netherlands, the safety of employees is regulated by the Working Conditions Act (Arbo). This Arbo law is a framework law. The Dutch standards NEN 3840 and NEN 3140, for the safe operation of high voltage and low voltage installations respectively, give further substance to the European standard. These NEN standards mention, among other things, Electrical Responsibility. Within these regulations, an owner may delegate the electrical responsibility to one person, the Installation Responsible Person (IV or NPcEI).


In a wind farm, the maintenance of both the high and low voltage installations is often assigned to one company. This maintenance provider is contracted to keep the installation in a good condition and to deliver the work responsibility (WV). The Installation Responsible should work independent of this maintenance provider to neutrally authorize the work activities. In a solar farm, the maintenance of high and low voltage is often split up.
