Willdan

Willdan provides energy and infrastructure services to utilities, state and local governments, and commercial customers. Its work spans energy program design and delivery, engineering, construction management, analytics software, and financial, economic, and strategic planning.

In energy programs the firm designs and administers utility programs, including direct install, electrification, and targeted load relief programs for existing buildings as well as new construction programs, and handles program administration, sales and outreach, contractor network oversight, technical services, and QA/QC. Grid work covers distributed energy resources such as solar PV, storage, cogeneration, wind, and fuel cells, microgrid design, automated demand response, and load procurement. A municipal services group supplies building and safety, code and fire plan review, inspections, city engineering, traffic and transportation engineering, GIS, studies, grant support, and local government staffing.

The company says it has delivered technical services for more than 60 years, has helped more than 100 utilities in the past 30 years, and has administered 120 or more programs. It states that its mature programs have served 440,000 customers and saved 9,600 GWh and 129 million therms, and that its municipal teams have worked with more than 97% of the cities in California. Recent announcements include acquisitions of a suburban Chicago power delivery engineering firm and a commercial energy consultancy, and selection for a $31 million renewable cogeneration design-build contract for a wastewater authority.

The published work is concentrated on utility programs, public agencies, schools, and large facility portfolios. An owner of a single commercial property should confirm minimum project size and whether services are available in their utility territory.
