2025 Energy Efficiency as a Resource Conference

Overview

The 13th biennial Energy Efficiency as a Resource conference will focus on policies and programs to reduce energy waste as we build the utility system of the future. This event will explore how efficiency efforts can expand and evolve to help utilities and policymakers overcome the challenge of rapid electric load growth while maintaining power reliability and customer affordability. The conference will provide a unique opportunity to interact with the key players in the utility energy efficiency arena.

In addition, ACEEE has collaborated with IEPEC to kickstart the week with its evaluation conference at the same venue as EER. These back-to-back events will provide the opportunity for broader networking and gathering of information from more experts in the field. IEPEC’s event will be held from Monday, October 6 through Wednesday, October 8, overlapping with the start of the EER conference on Tuesday, October 7. The EER conference will wrap up on Thursday, October 9.

Discount registrations will be offered to attendees who want to participate in both events. More information to come in summer 2025!

Program Highlights

Plenary Panel – Regional Roundup: Highlighting Recent Utility Energy Efficiency Wins and Spotting Challenges on the Horizon | Wednesday, October 8 (10:00 – 11:30 am)

Gain perspective on how utility energy efficiency goals and challenges vary across the country in this fast-paced and engaging panel. Regional energy efficiency organizations from across the United States will each share their top recent accomplishments and wins, as well as upcoming challenges they face in the coming years.

Lunch Keynote: Integrative Policy Strategies in Illinois to Deliver Efficient and Affordable Energy to Consumers | Wednesday, October 8 (11:30 – 12:45pm)

Doug Scott, chair of the Illinois Commerce Commission, will share lessons learned in Illinois, a state leading the way on future-looking energy policy, as the state has worked to braid together a range of regulatory, legislative, and administrative strategies to increase energy efficiency, move towards clean heating and transportation, and make sure the benefits of these policies reach low-income families.

Workshops

Residential Thermal Energy Storage for Load Shifting: A Collaborative Ideation Session on Utility Strategies to Deliver Value to Customers and the Grid | Tuesday, October 7 (3:00-5:00pm)

Thermal energy storage (TES) can enable load shifting of heating and cooling loads in buildings, helping utilities free up peak electricity for strategic priorities such as manufacturing or data centers, while helping customers save on their electric bills. We will summarize the latest research on the state of utility TES deployment, then bring together the expertise of the attendees to identify possible improvements to programs, rates, incentives, or other solutions that can help customers and utilities capture the benefits of residential TES.

*Available as an add-on to registration. Cost: $50

Closing the Equity Gap in Utility Energy Efficiency Programming | Tuesday, October 7 (3:00-5:00pm)

Research suggests that low- to moderate-income (LMI) customers are often underserved by most utility energy efficiency programs, despite having the greatest financial need. This workshop will convene utility program administrators and implementers to share best practices and case studies related to scaling low-income energy efficiency programs effectively. ACEEE moderators will present short introductions to a range of challenges in LMI programming, highlight utility successes, and facilitate breakout discussions. All workshop participants will receive a written summary of findings and key themes following the event.

*Available as an add-on to registration. Cost: $25

IEPEC & EER

For the first time, ACEEE and IEPEC are collaborating to bring you back-to-back conferences at the same venue—providing opportunities for broader networking, sharing insights with a wider audience, and gathering information from more experts in the field.

The International Energy Program Evaluation Conference (IEPEC) is a biennial professional conference for energy program implementers, evaluators of those programs, local, state, national and international representatives, and academic researchers involved in evaluation. The purpose of the conference is to provide a forum for the presentation, as well as a critique and discussion of objective evaluations of energy programs.

IEPEC will be held from Monday, October 6, through Wednesday, October 8, overlapping with the start of the EER conference on Tuesday, October 7.

★ Special Offer: Register for EER and receive $100 off your IEPEC registration!
