Our Power System

TVA’s power portfolio is dynamic and adaptable in the face of changing demands and regulations. Our emphasis has moved away from traditional coal-based production and toward cleaner forms of power generation, and today the power we deliver is nearly 60 percent carbon-free.

So that we remain responsive to the Valley's electricity demand on hot summer and cold winter days, we're adding more cleaner-burning natural gas units. To generate more carbon-free power, we’ve added the 21st century’s first new nuclear unit. As always, we generate clean, renewable power with our 29 hydroelectric dams. We have plans underway to build TVA's first utility-scale solar site and have contracted for more than a thousand megawatts of solar to help customers meet their renewable goals.
