As part of the owners engineering, but also as a separate request, Pondera can offer its services prior to and during the take-over phase. Before a wind turbine or other sustainable generator supplies power to the electricity network, the equipment must be tested. Although tests have already been carried out in the factory (FAT), tests will also need to be done on site (SAT). In order to verify that the generator has been correctly installed and that it functions properly, the commissioning phase can commence as part of the take-over process. Several tests and checks are performed during commissioning before the wind turbine becomes fully operational.

Following successful completion of commissioning, the wind turbine or solar farm can finally supply sustainable energy and the construction phase is completed.
