Grid Connection

Connect your installation to the grid with full compliance

From load flow study to operator validation, we guide you through every administrative and technical step of the grid connection process.

Our quality approach

  • Independent review by a second senior engineer
  • Compliance with IEC 60909, IEC 60038, IEC 60076
  • Use of certified software (PSS/E, PowerFactory, ETAP)
  • QAQC document archiving for 10 years

Frequently asked questions

Which grid code applies to my project?
The applicable grid code depends on the distribution or transmission network operator in your country. We identify and interpret this document for you, as it is often poorly documented.
My application was rejected by the operator, can you take it over?
Yes, we analyze the rejection reasons, complete or correct missing studies and reformat the dossier to the operator's specific requirements.
Do you work on HV connections (225 kV and above)?
Yes, we have experience with HV connections up to 225 kV and collaborate with partners for higher voltages (400 kV, 735 kV in Canada via NRPowerGrid).
