  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. Customer must move to an air conditioning system with a minimum Step 1 efficiency listed in the 2008 AC Rebate Matrix.
  3. The efficiency is based on the total system efficiency as verified by CPS Energy.
  4. Rebates will be based on the nominal tonnage of the new system rounded to the nearest ½ ton (6,000 BTUH).
  5. The rebate is based on the difference between the efficiency of the system installed and the minimum efficiency required.
  6. The application must include performance specifications, model numbers and serial numbers for all air conditioner units.
  7. Eligible systems must be over 5 tons total or a Three-Phase unit, regardless of size.
  8. Residential units can be installed to achieve a higher efficiency, but the total installed must be over 5 tons.
  9. Packaged Terminal Air Conditioners (PTAC) and Packaged Terminal Heat Pumps (PTHP) are eligible, but the total installed must be over 5 tons. [PTAC/PTHP efficiencies will not be listed in the 2008 AC Rebate Matrix; please call (210) 353-2728 to determine minimum efficiencies.]
  10. Totals less than or equal to 5 tons will be covered under the CPS Residential Air Conditioner Rebate Program.
  11. No rebate is available when moving from a water-cooled chiller to an air-cooled chiller.
  12. Rebate limit is capped at $50,000.

Large Commercial Lighting Retrofits of 100 KW or Greater Reduction

CPS Energy will aggressively pursue larger energy efficient lighting projects with demand reduction greater than 100 kW by offering incentive rebates to offset a portion of the client's capital investment. These rebates are offered to provide the demand reductions sooner rather than later so the benefits of avoided energy and capacity costs can start accruing in the near term.  Please call (210) 353-3591 for full details.

  1. The project must provide for an aggregate reduction of 100 kW or greater. 
  2. Rebates are calculated individually for each project.
  3. Total rebate will not exceed 75% of the total cost of the retrofit project as defined by the contractor invoice price.
  4. 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.
  5. 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
  6. Lighting Ballast accepted are GE Ultramax, Advance Optima, or a product with equivalent specifications.
  7. Bulbs must meet the following specifications
    o T8 bulbs must be 28 watts or less. Exceptions can be made if other bulbs actually reduce amount of energy required.
    o T5HO bulbs must be 54 watts or less.
    o 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
  8. Fixtures must be Lithonia, General Electric (GE), Cooper, Daybright or equivalent. CPS Energy reserves the right to determine if any fixture substituted meets the specifications.
  9. 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.
  10. 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.
