Columbia Water & Light provides rebates based on the overall capacity of a PV system (kW) as well as its energy production (kWh) during “peak” times. Peak times are periods of high system demand when electricity is most expensive for Water & Light to provide to its customers and normally occur on hot summer afternoons and evenings. The utility provides a premium rebate for PV systems designed to perform best during peak periods using azimuth, tilt and shading as determining factors. Net Metering Agreements and Rebate applications must be submitted by a Water & Light approved PV Installation Contractor.
