Are there any requirements to prove or guarantee energy savings?

Measures qualifying using the pre-qualified Eligible Energy Measures list method only need to meet the requirements indicated on the list under the measure name. Measures qualifying for an investor-owned utility (IOU) custom incentive automatically qualify for the program. For measures qualifying by the professional certification method, the Certified Energy Manager or Professional Engineer who is certifying the measures must provide an estimate of energy savings. This is not a guarantee but a good-faith estimate of savings based on accepted industry practices.
