摘 要：Comprehensive and integrated resource planning considers the potential for increases in energy efficiency to reduce the requirements for new generation and transmission investments. This study supports such planning efforts by developing robust estimates of the economically achievable potential for improving the energy-efficiency of homes, commercial buildings, and industrial plants located in the Eastern Interconnection. The approach of this study involves identifying a series of energy-efficiency policies and examining their impacts and cost-effectiveness using Georgia Tech's version of the National Energy Modeling System (GT-NEMS). The project emphasizes the impacts on electricity consumption, the levelized cost of policy-driven electricity savings, and distributive effects at the state and regional levels. Thirty-six states and the District of Columbia are covered by this study, and the time frame extends to 2035. Using GT-NEMS, we model twelve policy options designed to stimulate energy-efficiency investments and practices by providing better information, more effective regulations, and affordable financing. These policies are evaluated individually, combined into Policy Bundles and evaluated for each sector, and evaluated in an Integrated Policy scenario. While the policies are designed to address different market failures and barriers and to focus on distinct market segments and technologies, the level of savings driven by the policies diminishes as more policies are combined. We focus on the achievable energy-efficiency potential, which is the subset of the technically feasible and cost-effective potential that can be achieved through policy intervention. Based on GT-NEMS estimates from the Integrated Policy scenario, the twelve policies could significantly drive down energy consumption, reduce energy rates, and generate energy bill savings for end-users.
