How are custom incentives determined?

Custom incentives are based on the cost of installing the high-efficiency measures and the resulting energy and demand savings. In all cases, the high-efficiency measure must be cost-effective. For retrofit measures where the efficiency of existing equipment or systems is being improved, the incentive is up to 50% of the installed cost of the high-efficiency measure. For new construction or the purchase of new or replacement equipment, the incentive is up to 75% of the cost of the high-efficiency equipment over the standard efficiency equipment. In all cases, if the incentive results in a customer simple payback of fewer than 1.5 years, the incentive will be reduced to an amount that will result in a 1.5-year payback.
