About this incentive
City Water Light and Power (CWLP) offers rebates to help commercial customers increase the energy efficiency of participating facilities. Energy efficient air-to-air and geothermal are eligible for rebates which vary according to the technology type, cooling capacity, cooling efficiency, and category. The size of the rebate is based on British Thermal Units per Hour (Btu/h) cooling capacity, cooling efficiency and category, as defined by the program rules. Rebates on water heaters and heat pumps are also available to eligible commercial customers. Rebates are only available to CWLP electric customers and will appear as credits on customers' electric bills. Contact CWLP for more program information.
