Day & Zimmermann (D&Z) announced that the Tennessee Valley Authority (TVA) has awarded its maintenance and construction division a contract to perform maintenance and modification services for all of the utility’s hydroelectric dams, pumped storage hydroelectric, gas and coal facilities.

D&Z will also perform scaffolding, coatings, insulation, asbestos abatement and lead abatement work. The $985 million contract spans five years, with the option to renew for an additional five years.

D&Z has more than 25 years of experience working with TVA, according to John McCormick, president of D&Z’s maintenance and construction division. In April 2022, TVA named D&Z its 2022 Prime Supplier of the Year through TVA’s Diversity Alliance Program.

TVA is a corporate agency of the U.S. that provides electricity for business customers and local power companies, serving nearly 10 million people in parts of seven southeastern states. In addition to operating and investing its revenues in its electric system, TVA provides flood control, navigation and land management for the Tennessee River system and assists local power companies and state and local governments with economic development and job creation.

The electricity TVA delivers is nearly 60% carbon-free through its 29 hydroelectric projects, TVA’s nuclear fleet and other renewables such as solar. TVA owns four fossil plants, three nuclear plants, 29 hydro plants, one pumped storage hydroelectric plant, nine natural gas combustion turbine gas plants, eight natural gas combined cycle gas plants, one diesel generator site and 13 solar energy sites.

TVA is reducing its reliance on coal and plans to expand its natural gas fleet to provide the ongoing flexibility needed to reliably integrate more renewables.
