High-efficiency lighting retrofit

Reduce your costs with efficient lighting

Lighting accounts for 17 percent of electricity consumed annually in the United States, with another 4 to 5 percent used to remove waste heat generated by inefficient lighting fixtures.

Commercial office building operators spend about 29 percent of their operating budgets on utility bills. Lighting, cooling, and ventilation account for more than 60 percent of these buildings’ electricity use.

If you’ve never upgraded to more efficient lighting opportunities likely exist to enhance your efficiency, reduce energy costs, and reap attractive returns on your investment with our rebates.

But remember, rebates and lower operating costs aren’t the only advantages of high-efficiency lighting. Research indicates that efficient lighting also can contribute to productivity, quality control, security, safety, and reduced maintenance costs.

Eligibility

All commercial, industrial, and agricultural customers in Minnesota are eligible.

Eligible retrofits include light-emitting diode (LED) fixtures and lamps, high-efficiency fluorescent systems, and occupancy and daylighting based lighting controls. Guidelines

■ Rebates for retrofits from T12 fluorescent lighting systems to standard-efficiency

T8 fluorescent lighting systems no longer are available. An incentive for retrofits from

T12 fluorescent to low-watt T8 (28 watts per lamp or less) fluorescent lighting systems is available. ■ All rebates exceeding $4,500 must be preapproved. ■ A replacement system must meet minimum recommended Illuminating Engineering

Society lighting standards for illumination and be a permanent installation. ■ Otter Tail Power Company reserves the right to inspect and verify installations before issuing rebates. ■ Rebates also are available for lighting controls.

By automatically controlling lights based on occupancy or natural light levels, lighting controls can cut lighting energy costs as much as 50 percent.

We recommend storing old fluorescent lamps and HID lamps according to Minnesota Pollution Control Agency (MPCA) procedures:

■ Store in an area and manner that will prevent breakage. ■ Post notices to show employees where and how to store lamps. ■ If storage on-site isn’t possible, transport the lamps to a storage location. A hazardous waste manifest isn’t needed as long as lamps are transported to a site within Minnesota. Shipping papers are required.

■ Ballasts may contain polychlorinated biphenyls (PCBs). Storage and disposal of PCB ballasts must conform to the requirements of the Environmental Protection Agency and the MPCA. ■ For more information about fluorescent lamps, high-intensity discharge lamps, and ballast storage and disposal requirements, contact your local county recycling offices. They may have recycling programs in your area. Or call the MPCA at 800-657-3864. CIP rebates will not exceed 75 percent of installed costs. Funding limits and other program guidelines and limitations apply.
