Greenvolt Next is committed to the Distributed Energy Generation, as this is one of the main axes of energy transition and key to reduce the costs of energy bills. We have partnerships across Europe relying on local knowledge and market expertise.
We’re looking for an experienced Commissioning Engineer to take ownership of the commissioning process for utility-scale solar projects. You’ll be responsible for managing, executing, and documenting all commissioning activities, ensuring safe, compliant, and efficient grid connection and operation of large-scale renewable energy systems.
The role requires strong technical knowledge of HV systems up to 132kV, a solid understanding of protection systems, and hands-on experience delivering grid-connected solar projects. You’ll work closely with project engineers, ICP contractors, and local DNOs to bring each site online safely and on schedule.
You will be responsible for the execution of Hot and Cold commissioning, which will include visual inspection, IR testing, wiring continuity /point to point check, CT/VT IR test, ductor test, secondary current injection test and possibly hipot test. Functional operation of switchgear to include interlocking.
Key Responsibilities
* Lead and carry out the commissioning of utility-scale solar farms from initial testing through to grid connection and handover.
* Manage commissioning plans, schedules, and documentation to ensure full compliance with project and regulatory requirements.
* Perform testing and configuration of protection relays, including fault analysis, settings verification, and final approval with the DNO.
* LV cold commissioning.
* Commission and operate HV and LV switchgear, including the operation of circuit breakers and measurement of CT/VT values.
