Substation Design Support from Experienced Electrical Engineers

Ulteig’s substation engineering team has 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.

We can put our vast knowledge and experience to work for you, assisting you through the full engineering and design process  — from the development of conceptual design through detailed design, construction support and the energization stage.

Our project experience includes 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, client-specific standards and a full EPC/design build service. On every electrical substation design project, our top priorities are safety, quality, constructability, efficiency, budget and schedule.
