      Automate the basic engineering of your substation and reduce development time

      Increase the efficiency, power output, and ROI of your plant’s substation in just a few clicks

      Interconnection design

      Choose the interconnection

      • Arrangement, your call
        Single busbar, double busbar or line-to-transformer, with the consequences of each shown rather than assumed.
      • Conversion level and transformers
        Set the voltage conversion and power transformers for the plant you are actually building.
      • Capacity that matches the plant
        Size the facility for the load growth and transmission capacity your project needs, not a default.
      Customize substation design

      Match it to the grid you are connecting to

      • TSO and DSO requirements
        Choose the circuit arrangement and power transformer size that comply with the rules for your project type and location.
      • Parameters you control
        Adjust the parameters behind the calculation so the result meets the requirements at your point of interconnection.
      • The plant's own constraints
        Medium voltage lines, capacity and environmental conditions all feed the substation design.
      Interconnection application process documentation

      Cost it and document it

      • Fast calculations, basic engineering out
        Run the substation calculation and get the basic engineering for a cost-effective interconnection facility.
      • Price the arrangement
        Choose the number of transformer bays and busbars and see what each choice does to cost.
      • Documents you can issue
        Results come out as documents for the interconnection facility, and the AI Agent Enverus ONE Power Analyst iterates against your grid constraints rather than you rerunning each option.
