Lighting is the second largest portion of a business’ energy bill. On the average, interior lighting accounts for 28 percent of a company's energy consumption. However, with advanced lighting technologies, there has never been a better time to upgrade the lighting in your facility. High-efficiency upgrades can save you energy and money, while improving the light quality and output in your buildings.  In many  lighting upgrades, a business can expect to see a payback on its investment within 18 months.

For small and mid-size companies, our custom rebate program may be a better fit. Rebates are offered for small upgrade projects of 50 fixtures or less.

1. All rebate applications are subject to the general provisions including a site visit from CPS Energy personnel both before start and after completion of the project.
2. Lighting eligible for the rebate includes: T8 with an electronic ballast of 28 watts or less, compact fluorescent lamps with installed locking disks, LED Lamps and Fixtures and LED Exit Signs. 
3. High efficiency electronic ballast must be used. 
4. Base lighting use is calculated by determining the number and type of lights existing prior to the change-out.
5. Rebate is based on the difference in KW between existing and installed lights.
6. Rebates are calculated individually for each project.
7. Total rebate will not exceed 75% of the total cost of the retrofit project as defined by the contractor invoice price.
8. The contractor must submit a detailed Lighting Economic Analysis work sheet to the facility owner that details the quantity and type of existing lights, the proposed quantity and type of lights to be installed, kW and kWH savings, estimated energy cost savings and the proposed cost of the retrofit work.
9. The contractor will furnish to the owner a written one-year guarantee on work and materials provided. The contractor supplies manufacturer’s written warranty on the materials if applicable. The guarantee should be effective from the date.
10. Lighting Ballasts that are accepted are GE Ultramax, Advance Optima, GE Proline or a product with equivalent specifications.
11. Bulbs must meet the following specifications:
    a. T8 bulbs must be 28 watts or less. Exceptions can be made if other bulbs actually reduce amount of energy required.
    b. T5HO bulbs must be 54 watts or less.
    c. Compact fluorescent bulbs must have locking discs and must meet the requirements below:
    • 40 watt - 9 watt or less
    • 60 watt - 13 watt or less
    • 75 watt - 18 watt or less
    • 100 watt - 23 watt or less
12. A refund shall become due and payable to CPS Energy if the customer fails to ensure CPS Energy that the rebated lighting equipment will be properly maintained for at least 7 years from the time of rebate.
13. CPS Energy or its designated agent will perform a pre-inspection of the site; results of the pre-inspection and proposed retrofit will determine rebate eligibility and provide/confirm the data for incentive calculation.
14. Savings for new construction will use the IECC 2001 electrical standards (watt/ft2) as the base.  See the U.S. Department of Energy website www.energycodes.gov to download “Comcheck.” 
    a. Burn time for each light is requested to calculate energy savings and help determine total savings.
    b. Outside lighting is not eligible with the exception of LED lighting normally in operation between the hours of noon to 7:00 p.m., Monday through Friday.
    c. Occupancy sensors are not included.
    d. The Comcheck must be uploaded for these projects.

Custom Program for Light Fixtures

CPS Energy also offers a custom program primarily for small and mid-size commercial customers:

• This measure is designed for 50 or less fixtures.  If 50 fixtures are exceeded, the rebate should be applied for under the “Commercial Lighting Equipment” program.
• Rebates will be based on a per fixture basis – no bulbs will be included in the program rebates. 
• Any reduction in lighting usage will be paid based on the 2009 Lighting Rebate Matrix.
• No pre-inspection necessary for this program. Random post-inspections will be conducted. 
• Applications for this program can be obtained through our Custom Programs category.
