Substation Design



Ulteig’s top priority is to fully understand its clients’ needs. We know that each organization and project is unique, so we strive to view our clients’ challenges by grasping their perspective. Ulteig constantly challenges itself to find and provide the best solution for every need. 

Ulteig is its people. Our people place listening, communicating and responding to the client’s needs as top priorities. Ulteig in return places its people as a top priority. Across the company, this creates an environment of committed, collaborative individuals and teams which ensure our clients receive a technically insightful, success-driven, client-focused, “A-team” solution for every need.   

Ulteig’s robust substation team holds professional registrations across the US. We have engineered and designed more than 1,000 high-voltage substations, switching stations and interconnect stations — from 12.5 kV to 500 kV — for investor-owned utilities, cooperatives, municipalities, contractors and developers.

Ulteig provides full engineering and design from the development of conceptual design through detailed design, construction support and the energization stage. Project experience includes but is not limited to: system studies, EHV and HV air-insulated and gas-insulated switchyards, static and dynamic VAR compensation, renewables interconnections, 3-D modeling, NERC and FERC requirements, relay settings, site development, testing and commissioning, diverse client specific standards and a full EPC/design build service. Safety, quality, constructability, efficiency, budget and schedule are at the forefront of what Ulteig considers for every task at hand. 

Ulteig solves our clients’ needs while building trust. As trust is earned, we work toward a dynamic, long-lasting partnership. If you have further questions about what Ulteig can do to support you, we are ready to listen and solve.
