The Tennessee Valley Authority (TVA), a U.S. corporate agency that provides electricity for seven southeastern states, has announced incentives for ultraviolet germicidal irradiation (UVGI) in commercial HVAC systems, the first type of rebates any energy company in the U.S. has given for UV.
The incentive is $30 per ton of cooling capacity for in-duct mounted UGVI systems and is focused on UV-C-band (100‒290 nm) emission to kill coronavirus and other pathogens in the airstream. It targets commercial applications including hospitals, schools, reception areas, retail establishments, nursing homes, churches, hairdressers, business offices, and industrial facilities.
