TriAxis engineers can provide electrical power design services to developers and contractors of utility-interconnected photovoltaic (PV) systems.

Support for smaller-scale localized generation projects (typically less than 100 MW) includes:

• collection systems layout and circuit sizing
• conceptual and final substation design
• transmission line conceptual and final design
• feeder voltage drop analysis
• feeder harmonic assessment
• transfer trip system scoping
• protective relay requirements definitions
• assistance with the development of communication path specification
• power factor assessment
• technical review of interconnection agreements for feasibility and implementation

Support for large projects (typical plant capacities in excess of 100 MW) includes:

• developer and contractor assistance includes conceptual designs for EHV generation tie-lines used for preliminary design and approval stages
• complete design solutions for the PV overhead and underground collection system
• project substation design
• EHV transmission line design
• develop project scoping documents
• develop project budget estimates
