Northeast Regional Energy Efficiency Database, Program and Measure Data

Northeast Regional Energy Efficiency Database (REED) 2021 data update

Release date: September 30, 2024

Electric and natural gas utilities and state energy efficiency (EE) organizations offer incentives that are an important component of evolving state and local EE policies. To understand how these incentives affect energy consumption and technology choices in buildings, we incorporate nonfederal EE incentives for a variety of end-use technologies into our National Energy Modeling System’s (NEMS) Residential Demand Module (RDM) and Commercial Demand Module (CDM). We use NEMS to produce long-term projections of energy use within the United States.

The RDM and CDM represent consumer choice among various energy-consuming equipment in buildings, ranging from technologies that meet federal minimum EE standards to more efficient alternatives. These modules subtract incentives (equipment subsidies or rebates) from installed costs for equipment or appliances that meet or exceed ENERGY STAR® specifications in their respective technology choice menus. This approach lowers the relative cost of high-efficiency equipment.

To enhance our representation of state and utility EE programs in NEMS, we contracted with the Northeast Energy Efficiency Partnerships (NEEP) to characterize these programs in the Northeast in fiscal year 2023. As part of this contract, NEEP updated its Regional Energy Efficiency Database (REED) to include 2021 incentive data for the District of Columbia and eleven states in the New England, Middle Atlantic, and South Atlantic Census Divisions. REED provides information on several metrics for energy efficiency programs, including:

Annual and lifetime energy savings

Peak demand savings

Program expenditures

The cost of saved energy

Program funding sources

Avoided CO2 emissions

REED incentive data are available to the public by request on NEEP’s REED website. As part of this contract, NEEP also updated the Supporting Information report. The report provides information about each state in the REED database, which now sincludes 2021 data. The report also provides details about program administrators and reporting procedures as well as evaluation, measurement, and verification practices. It also provides information about NEEP’s energy savings assumptions and equations underlying the REED database.
