Air QualityThrough the power distributors of the Tennessee Valley, TVA provides more than eight million customers with reliable electric power at an affordable price. The massive public power system operated by TVAthe largest in the nationprovides public service that is unfettered by the need to generate profits. There are other constraints on the system, though. Public service means public responsibility, and power generation across an 80,000-square-mile service area cannot help affecting the environment. More than half of TVAs power is generated by the burning of fossil fuels, and this process inevitably releases chemical emissions into the atmosphere. TVAs aim is to balance the need for low-cost, reliable power with the necessity of protecting the environment we all share. How Clean Is the Air? Air quality standardsCheck here for information on the federal environmental standards that affect TVAs power generation. On the AirThese pages present technical reports on important air quality issues. Scientific papersTVA carries out many research projects related to air quality and other environmental issues.
