Columbia Water & Light - Solar Rebates
Administered by Columbia Water & Light
City of Columbia Utilities offers $500 per kilowatt rebates for solar photovoltaic systems, with additional premium rebates for systems designed to perform best during peak demand periods. Federal tax credits (30% through 2032, declining to 24% by 2034) stack on top of utility rebates, and the utility also provides PV system loans up to $15,000 for residential customers—contact the utility at 573.441.5528 or [email protected] with your system details to get a rebate estimate.
Systems must meet pre-project approval and the utility's interconnection and net metering requirements; contractors should consult CWL's solar rebate calculator (which factors azimuth, tilt, and shading) to estimate customer rebates. The rebate is straightforward—$500 per kW, with premium rebates available for peak-time optimization—making it easy to present total project costs and incentives to customers.
CWL administers rebates at $500 per kW capacity plus performance-based premium rebates tied to azimuth, tilt, and shading during peak periods; all energy production accrues to the utility under net metering agreements. Residential customers access loans up to $15,000 and commercial up to $30,000, with federal tax credits (30–24% through 2034) stacking on top, creating a comprehensive incentive structure to drive distributed solar adoption among both residential and commercial rate payers.
