Safe and Reliable Grid Connection

Utility-scale solar and BESS projects require seamless connectivity to the national power grid. The technical requirements of network operators (especially Fingrid) are exceptionally strict and require specialized expertise.

NordEPC specializes in high and medium voltage engineering. We are responsible for optimizing the entire electrical system from the inverter to the main grid, ensuring power quality, safety, and code compliance.

  • 110 kV and 400 kV substation design
  • Load Flow & Short Circuit calculations
  • Protection relay coordination and earthing design
  • Fingrid VJV/SJV compliance verification
Do you perform Fingrid-compliant grid connection studies?
Yes. We handle grid connection studies, power quality measurements, and ensure the system meets Fingrid's strict grid code (VJV/SJV) requirements.
Do you also design 110 kV substations?
Yes. We design main transformers, 110 kV or 400 kV substations, protection relay coordination, and the entire medium voltage (MV) network to optimize power transmission.
What do you do in power system modeling?
We use industry-leading software for Load Flow & Short Circuit calculations, harmonic distortion analysis, and protection coordination.
