Based on the cost-effectiveness methodology outlined here, the portion of the regional residential potential that is cost-effective is 100 average megawatts in 2027, 280 average megawatts in 2032, and 510 average megawatts in 2041. The cost-effective potential by measure bundle for 2027, 2032, and 2041 is provided in the table below. The purpose of this table is to show the major sources of energy efficiency identified in the Council’s 2021 Power Plan. It is not intended to dictate either the specific measures or the pace of their acquisition to be included in utility or system benefits charge administrator programs.
