What RLC Engineering does

RLC Engineering is a privately held engineering consulting firm founded in 2006 by Rick Conant in Hallowell, Maine, providing professional power systems engineering services to electric utilities, regional grid operators (ISO-NE and NYISO), renewable energy developers, and grid infrastructure contractors across the Northeast, Mid-Atlantic, Southeast, and Eastern Canada. The firm employs 110+ technical professionals across three Maine offices (Hallowell headquarters, South Portland, and Bangor) and operates as a professional limited liability company (PLLC) under founder-led, independent ownership with no external capital.

The firm's service portfolio is organized into five core lines: Power System Studies (transmission, distribution, and interconnection analysis), Power Delivery (substation, transmission line, protection & control, and civil/structural design from 4 kV to 500 kV), Power Generation (solar, wind, and battery storage full-lifecycle engineering), Power Engineering (energy management, microgrids, mechanical design, CHP), and Project Management. RLC executes work using industry-standard tools—PSS/E, PSCAD, ASPEN, EasyPower, CYME, SKM, Synergi, PowerTools for Windows, ATP, and TARA/PSLF—augmented by a proprietary hourly congestion analysis model and a Non-Transmission Alternative (NTA) framework. Its engineers hold PE licenses in multiple states and have performed stability analyses supporting more than $3 billion of grid expansions in Maine and New England and engineering for over 4 GW of solar, wind, and storage.

RLC generates revenue through professional services on a project-by-project, quote-based pricing model, with engagements spanning feasibility studies, interconnection applications, detailed design, permitting, commissioning, and operations support. Customer acquisition is driven by direct enterprise relationships, technical white papers, and industry working-group participation rather than mass-market channels. The firm has no disclosed outside investors, no subsidiaries, and no patent portfolio, and operates with a founder-controlled ownership structure.
