Knoxville Officials Explore Norris Dam’s Role in Renewable Energy Ahead of National Hydropower Day

Knoxville Officials Tour Norris Dam to Learn About Hydropower

Knoxville, TN – A group of Knoxville officials and government staff embarked on an enlightening tour of Norris Dam, a key player in the Tennessee Valley Authority (TVA) hydropower system, located just 25 miles north of Knoxville. The tour occurred ahead of National Hydropower Day on August 24, where the contributions of hydropower will be celebrated nationwide.

Behind-the-Scenes Opportunity

The idea for the tour took shape during a breakfast meeting held for the Knox Education Foundation in late July. The TVA’s Community Relations Manager, Bryan Johnson, suggested the visit to Knox County Commissioner and mayoral candidate, Larsen Jay. Given the significance of Norris Dam in the context of renewable energy, the officials were eager to explore this historical site.

Erik Bodiscomassink, who manages Norris Dam and two other TVA hydro plants, guided the tour. The event not only highlighted the dam’s tremendous hydropower contributions but also showcased the aging yet resilient public infrastructure critical to the region.

What Makes Norris Dam Special?

Norris Dam, built between 1933 and 1936, stands 265 feet tall and stretches 1,860 feet long. It serves a monumental role, capable of providing electricity to approximately 75,000 homes. To generate this power, two large turbines utilize an astonishing 24,000 gallons of water every second.

The dam is classified as a gravity dam, meaning it relies on its weight to remain stable. In the core of the mammoth structure lies an impressive sluice gate gallery, an expansive space used for managing water flow. Some officials were so taken with its unique features that they likened it to film set locations, with suggestions resembling teenage mutant ninja adventures hidden below urban landscapes.

Operations and Responsibilities

During a typical day, only five TVA staff members oversee operations at the dam. Most of their work revolves around preventative maintenance. The dam is mostly automated and monitored remotely, which allows for reduced personnel presence on site during off-peak hours. Bodiscomassink noted that many of their responsibilities involve ensuring that everything runs smoothly and addressing issues proactively.

The dam structure houses hydraulic valves designed to control water release into the Clinch River. This feature is pivotal for managing water levels and ensuring environmental health downstream. In times of high demand, Norris Dam plays a vital role in supporting energy needs.

Environmental Considerations

The TVA emphasizes maintaining water quality and supporting wildlife in the region. As water is directed from the dam, oxygen is added throughout the process to aerate it. This practice is essential for sustaining aquatic life downstream. To ensure the safety of local fishers, sirens sound before significant water surges occur, enabling them to prepare accordingly.

A Popular Destination

Over the years, Norris Dam has seen its fair share of visitors. The dam features a visitor center and various educational offerings that attract hundreds of thousands of people. These experiences not only provide insight into hydropower but also promote awareness of the importance of renewable energy.

Marking the dam’s 80th anniversary in 2016, TVA staff undertook the restoration of a mural depicting the TVA system. Originally painted in the 1950s, the mural had been covered with carpet-like material. With meticulous effort, specialists restored it, reviving a piece of history amid the modern workings of the dam.

Conclusion

The tour culminated with personal reflections on the critical role Norris Dam has played in the region’s energy landscape. As officials explored the inner workings of this historic dam, the event served as a reminder of the importance of investing in sustainable energy solutions for future generations.
