For Your Industry


If you manage an industrial facility, the sheer size of your operation has already demonstrated the importance of the efficient use of energy. The industrial sector alone accounts for about one-third of U.S. energy use.

Customized TVA technical assistance is available to industrial users of power to devise plant-wide, holistic approaches to energy savings. TVA helps customers maximize efficiency, control expenses and boost their bottom lines.

In addition, program participants may be eligible for financial incentives to implement energy-saving changes in their operations and plant.

Energy savings by its customers lowers the amount TVA must spend purchasing power to meet demand. Energy efficiency programs can save you money, and help TVA keep energy costs lower for consumers of power throughout the Tennessee Valley.

Members of the TVA Trade Ally Network can provide energy-saving solutions for your facility that will help you save money. 

Lighting is a significant component of any company’s energy use. The Energy Star program suggests ways industrial plants can save on lighting. Also check with your local utility to see if it offers programs or incentives to improve your lighting efficiency.


    • Turn off lights in unoccupied areas. An awareness program will help staff get in the habit of switching off lights in areas (such as warehouses or parts production areas) where they are often not needed.
    • Establish lighting level standards. Lighting levels (expressed as lumens per surface area) should be set in each section of a plant. Energy is saved by maintaining different levels as needed for different work areas.
    • Use automatic lighting controls. Lights can be shut off by controls that turn off lights when a space is unoccupied. Savings of 10 percent to 20 percent of lighting energy can pay for the system in a year.
    • Replace incandescent lamps with compact fluorescent lamps (CFLs). An energy efficient fluorescent lamp lasts roughly 10 times longer than an incandescent light. The payback period can be as low as five months.
    • Replace T-12 with T-8. Older T-12 lighting tubes consume significant amounts of electricity. T-8 lighting tubes have about twice the effectiveness of T-12 tubes and can last 60 percent longer. Typical energy savings are about 30 percent.
    • Replace mercury lamps. Where color rendition is critical, metal halide lamps can replace mercury of fluorescent lamps with energy savings of up to 50 percent. Where color rendition is not critical, high-pressure sodium lamps offer energy savings of 50 to 60 percent.
    • Consider replacing high-intensity discharge (HID) lighting with high-intensity fluorescent lights. Traditional HID lighting can be replaced with T-5 high-intensity fluorescent lighting systems, which incorporate high-efficiency fluorescent lamps, electronic ballasts, and high-efficacy fixtures that maximize output. The payback period is typically below three years.
    • Replace magnetic ballast with electronic ballast. Ballast regulates the amount of electricity required to start a lighting fixture and maintain a steady light output. Electronic ballast can use 12 to 30 percent less power than magnetic ballast.
    • Use energy-efficient exit signs. Energy costs can be reduced by switching from incandescent lamps to light-emitting diodes (LEDs) or radium strips in exit signs. LEDs reduce electricity use by 80 to 90 percent and last 10 times longer.

Light-emitting diodes are collections of small lights that glow when electrons pass through a semiconductor material. LED lighting is more efficient than incandescent and as efficient as or better than fluorescent. It lasts longer than either alternative. TVA is taking part in a multi-year research project to test LEDs for street and area lighting in several Tennessee cities. Such lighting has the potential to reduce energy consumption, maintenance costs and light pollution. 

When qualifying industries make an investment in energy savings through TVA, they may qualify for an incentive payment that will help offset some of their investment costs. These incentives are available for projects that help reduce energy intensity in your facility.

Incentives vary according to the level of customer power contract demand:
