Sage Renewable Energy Consulting

What Sage Renewable Energy Consulting does

Sage Renewable Energy Consulting is a vendor-neutral energy advisory and project management firm that helps public agencies, school districts, commercial and industrial organizations, and nonprofits reduce energy costs and meet decarbonization goals. Founded in 2009 in Marin County, California by David Williard, Tom Williard, and Brent Johnson, the firm evolved from Sustainergy Systems (founded 2005 by David Williard) into a multi-vertical clean energy practice. Its services span solar PV consulting, wind, energy storage, EV planning and fleet electrification, microgrid development, zero net energy planning, energy efficiency and building optimization, and PPA buyout analysis, delivered through end-to-end project management from feasibility through procurement, implementation, and operations.

Sage's business model is professional services fee-based: engagements are quote-based and tailored, with a no-cost initial consultation used to qualify prospects. The firm sells on the strength of its vendor-neutral positioning and a 70%+ client repeat rate, supported by marquee outcomes including management of over $2 billion in cumulative energy projects, more than $350 million in documented client energy savings, and the largest contracted solar commitment by a school district in North America (24.5 MW for Kern High School District). The firm has historically operated with 1-10 employees and a California/Western US geographic focus, targeting three primary verticals: education, government, and commercial & industrial.

In 2021, Sage was acquired by NV5 Global, Inc. (NASDAQ: NVEE) and now operates as part of NV5's Clean Energy service line, leveraging NV5's 100+ office footprint, engineering platform, and federal/state/local government relationships to extend its reach. As an acquired subsidiary within a public-company parent, Sage's independent growth trajectory is no longer separately reportable, but its brand, advisory methodology, and client relationships remain embedded within NV5's broader infrastructure and built-environment consulting franchise.
