Expanding the Energy Savings Pie: Attribution Frameworks to Align IRA Home Energy Rebates and State Programs

Inflation Reduction Act (IRA) Home Energy Rebates offer state energy offices (SEOs) opportunities for unprecedented investments in electrification and decarbonization across the residential sector, and implementing these rebates with existing energy efficiency programs can expand the impact of the rebates and increase efficiency in program delivery.

Combining IRA rebates with existing energy efficiency programs may require states to adjust the regulatory requirements for energy efficiency program administrators (PAs). These discussions will largely focus on the questions of whether program administrators can credit savings from IRA funds toward their own portfolio, known as attribution of savings.

To help state energy offices, utility regulators, and other stakeholders navigate discussions of attribution with IRA Home Energy Rebates, NEEP convened a group of experts in the field of evaluation, measurement, and verification (EM&V) to help NEEP establish four frameworks to guide states in determining how best to attribute savings from programs that combine IRA Home Energy Rebates with existing energy efficiency efforts.
