High Voltage Support of Solar Interconnects

Large ground-mounted solar photovoltaic panels angled toward the sun on a utility-scale solar site, showcasing Halker’s renewable energy engineering expertise in high-voltage solar interconnect design, grid integration, and resilient power infrastructure.

As renewable generation continues to expand across Colorado and the greater U.S. power grid, utility owners and developers face complex technical and regulatory challenges in safely integrating new solar and energy-storage assets. Existing substations often require significant upgrades to accommodate solar interconnections, while interconnection studies and preliminary designs must meet stringent Regional Transmission Organization (RTO) and Independent System Operator (ISO) requirements for voltage stability, protection, and control coordination.

City-Operated General Electric DER Adoption

High-voltage transmission structures and substation equipment under overcast skies, illustrating Halker’s expertise in supporting city-operated distributed energy resource (DER) adoption and modern electric infrastructure planning.

A city-operated utility launched a Smart Grid Test Bed pilot program across three metropolitan areas to better understand how Distributed Energy Resources (DERs) could be effectively integrated into their power systems.
