What Solas Energy does

Solas Energy US is a Fort Collins, Colorado-based energy consulting and project management firm founded in 2009 that provides owner's engineering, owner's representation, construction management, technical and commercial due diligence, and project development support for utility-scale wind, solar, energy storage, transmission, and substation projects. The company sells bespoke professional services engagements — typically fixed-fee or time-and-materials contracts — to enterprise buyers including renewable energy developers, utilities, independent power producers (IPPs), and infrastructure investors such as Global Infrastructure Partners. Solas Energy US has supported more than 100 GW of renewable and storage projects since inception, including gigawatt-scale installations such as the 3 GW+ Edwards-Sanborn Solar + Storage project for Terra-Gen, the 1,400 MW Puget Sound Energy renewable portfolio, and 1,160 MW of operational compliance work for Onward Energy.

The firm operates with no proprietary software or technology platform; its offering is delivered by senior human experts led by founder/CEO Evelyn Carpenter (a licensed professional engineer) and a team of directors and senior associates with 17–45 years of industry experience. Go-to-market is sales-led, leveraging industry reputation, enterprise relationships, referrals, RE+ conference presence, and earned media. Revenue streams cover (a) consulting and advisory (due diligence, strategic consulting, permitting/regulatory), (b) project and construction management (owner's engineering, owner's representative, on-site construction management), and (c) development support (feasibility, resource assessment, interconnection, land acquisition).

In September 2025 the firm separated its brand from its former Canadian collaborator (Solas Energy Consulting Inc.) and launched a broader US strategy covering data centers, utilities, high-voltage transmission, and conventional generation, deepening its strategic partnership with Invera Energy — a separate Fort Collins firm led by the same CEO — to deliver a combined full-spectrum energy consulting offering across renewables, storage, transmission, and conventional generation.
