CSI-Thermal Program Incentive Levels

The CSI-Thermal program provides rebates to utility customers who install solar thermal systems to replace water-heating systems powered by electricity or natural gas.

On January 29, 2015, the Commission adopted Decision 15-01-035, which modified the Program's incentives for a second time, as shown in the tables below. The new rebate levels apply to all applications received on or after July 23, 2014.
