Tetra Tech provides lifecycle services for the electric generation industry. For more than a century, electricity created through fossil fuel combustion has met the nation’s base load and peak demand for power. As markets change and regulatory standards tighten, the electric generation industry must constantly evaluate operational risks as well as carefully plan for new facilities. Tetra Tech has the experience, resources, and financial strength to support the full range of projects for the electric generation industry—from new development to repowering, retrofits, and management of issues at existing facilities.

Tetra Tech is consistently ranked in the top 10 for Power and Cogeneration by Engineering News-Record. We have provided environmental, design, and construction services to support project development, construction, and operations on more than 1,000 power projects around the world. Our team has successfully permitted more than 50,000 megawatts (MW) of generating facilities and has provided strategic transactional and compliance support for numerous additional facilities.

Our experience in power facility construction provides not only practical knowledge of cost-effective, safe, and operationally efficient strategies, but also the opportunity to directly meet our clients’ construction needs. Tetra Tech has the financial strength, experience, and resources to support engineering-procurement-construction, balance of plant, and construction projects for conventional power plants, while always keeping safety at the forefront of every project.
