What Electrical Consultants does

Electrical Consultants, Inc. (ECI) is a private, employee-owned engineering and consulting firm founded in 1985 and headquartered in Billings, Montana, that provides comprehensive design, engineering, and construction services for power-delivery infrastructure across North America. The firm serves investor-owned utilities, public power utilities, municipalities, and rural electric cooperatives, executing projects ranging from substation design and transmission/distribution line engineering (overhead and underground, up to 765 kV EHV) to power system studies, protection engineering, SCADA integration, environmental permitting, GIS/survey, and right-of-way acquisition. Its wholly-owned subsidiary, EPC Services Company (EPCS), established in 2000, provides design-build (Engineer-Procure-Construct) execution, electrical testing, and maintenance, allowing ECI to deliver projects from conception through commissioning on a vertically integrated basis.

The firm's market position is concentrated in utility-scale renewables and energy storage: source materials cite involvement in 28% of U.S. utility-scale wind projects, 45% of U.S. utility-scale solar projects, and approximately one-third of U.S. utility-scale battery energy storage system (BESS) projects since 2009, with 5,000+ MW of BESS installed. Strategic acquisitions of Relay Application Innovation, Inc. (2020), CASCO Systems (2021), and TransCo.Energy (2025) have expanded capabilities in system protection, IEC-61850 design and cyber security, and geographic reach along the Eastern Seaboard. The firm operates through 30+ regional offices across the United States and Canada, employing nearly 1,000 professionals including engineers, project managers, designers, surveyors, environmental planners, and construction staff.

ECI's revenue model is professional services plus managed services, billed primarily through project-based contracts and multi-year master services agreements. Pricing is quote-based and not publicly disclosed, reflecting the enterprise nature of utility engagements. Customer logos include Florida Power & Light, Invenergy, NextEra Energy Resources, and large industrial clients such as petrochemical, mining, and water/wastewater operators; the firm is also RUS-qualified to serve rural cooperatives under USDA loan standards. Ownership combines an Employee Stock Ownership Plan (ESOP) with private ownership opportunities for staff — no external private equity or venture capital was identified in the source material.
