How UVGI helps the environment—and your business

Business & Industry / Incentives / Ultraviolet germicidal irradiation

Ultraviolet germicidal irradiation (UVGI) is becoming increasingly popular across the globe, especially as a cost-effective alternative to chemical disinfection.

Ultraviolet Germicidal Irradiation (UVGI) technology offers the potential to increase safety and health in the areas in which the technology is used. UVGI may help to minimize the spread of certain airborne pathogens. TVA is offering eligible participants $30 per ton toward the purchase and installation of UVGI in your business’s HVAC ductwork system.

UVGI uses UV-C light, a short wavelength ultraviolet light, in an attempt to inactivate certain pathogens. In 1903, Niels Finsen won the Nobel Prize for his work using UV rays to treat disease. UVGI has been commercially available since the 1930s when Westinghouse quickly commercialized the low-pressure mercury vapor germicidal lamp.

UVGI systems, which can operate year-round, may help reduce and deactivate certain airborne pathogens.

*All incentives are subject to approval by TVA and your local power company and are contingent upon available funding.

**Location may be eligible if UVGI system near the coil is specifically designed for air pathogen inactivation.

TVA’s incentive offering is limited to in-duct UVGI. The following are not eligible for this incentive at this time:

  • Surface Irradiation (including mobile UVGI units and chemical treatments)
  • Fixed Upper Room Air UVGI
  • Fixed Air Sanitizing UVGI
  • UVC Light Fixtures
  • Increased Ventilation
  • Needlepoint Bipolar Ionization
  • Bipolar Ionization
  • Particle Excitation
  • Hands Free “Touchless” Technology
  • Temperature Kiosks
  • High Volume Low Speed (HVLS) Fan and UVC ?xture combo
  • Photohydroionization (PHI)
  • Photocatalytic Oxidation (PCO)
  • UVGI systems designed only for coil defouling


The installation and use of UVGI does not eliminate the possibility of pathogen transmission. TVA does not make any guarantee or warranty of any kind, expressed or implied, with respect to or in connection with UVGI. TVA disclaims all warranties and does not warrant the safety, reliability, durability, effectiveness, or performance of UVGI. UVGI technology that is sold or distributed with claims that the product can be used for preventing, destroying, repelling or mitigating any pest (including viruses or bacteria) is regulated by Environmental Protection Agency (EPA) under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Participants must certify that UVGI devices comply with all applicable FIFRA requirements and corresponding EPA regulations.
