This report reflects work performed under contract with the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy. The research focused on applying the result of EPRI’s 2014 US Energy Efficiency Potential Study which was conducted at the Census division level and developing a method to apply the division level results to the state level by customer class and by end-use.
The state allocation shows that every state has a large amount of electric energy efficiency potential that can be utilized as a cost-effective energy resource. This cost-effective electric potential grows over time as equipment reaches the end of its useful life and is replaced by a cost-effective efficient replacement. In total GWh, this energy efficiency economic potential in 2035 ranges from 901 GWh in Vermont to 87,336 GWh in Texas, reflective of the both electric loads and the types electric services in each state.
Finally, to understand the potential to bring additional technologies to market and the impact that added incentives can have on energy efficiency potential, the national model and state allocations were re-run with differing levels of incentives. These results, which vary by state, show both the direct impact of incentives as well as potential opportunities to increase energy efficiency through cost reductions.
