The industrial sector has a wide range of segments, end-using equipment, and function. The energy efficiency measures are defined as a function of the end-use loads and there is significant diversity in the number and type of industrial efficiency measures. The industrial measure bundles are shown in the table below.

Major and New Industrial Measures
The industrial sector energy efficiency potential assessment for the 2021 Plan has undergone a major revision since the Seventh Power Plan. There are new measures and significantly updated analysis for existing measures.
The industrial sector is dominated by electric motor loads. NEEA, the RTF, and U.S. DOE have conducted substantial research and analysis regarding motor-driven systems including pumps, fans, air compressors, and advanced motors. This work is largely new since the Seventh Plan and has been incorporated into the 2021 Plan. Based on this research, the 2021 Plan includes a robust amount of energy efficiency potential for these products (over 380 average megawatts).
Heating, ventilating, and air-conditioning (HVAC) measures were also included in the industrial assessment for the first time. The HVAC measures in the 2021 Plan represent a range of options that industrial facilities may use to provide comfort conditioning to employees (approximately 32average megawatts).
Energy management is also a significant measure category (140 average megawatts). This category represents facility-wide adoption of energy efficiency primarily through the Strategic Energy Management (SEM) and similar programs offered throughout the region. There are two levels of SEM. The first level is defined as the traditional achievable amounts of energy efficiency and at a cost realized through recent program activities. The second level of SEM represents future potential that is more difficult to achieve either at smaller facilities, or deeper achievements at facilities that have already achieved level 1. The cost of SEM level 2 is higher than level 1.
Water supply and wastewater treatment are new segments in the industrial sector for the 2021 Power Plan. In prior plans, these segments were considered part of the commercial sector. This change was made to better align with utility program functions (i.e., utilities offer energy efficiency to the water and wastewater segments through their industrial programs).
Industrial Measures Not Included in 2021 Plan
There were some unique/specific measures eliminated from the 2021 Plan that were in prior plans because they are subsumed in broader categories such as pumps, fans, or advanced motors. It is likely that there are additional energy efficiency measures and opportunities in the industrial sector beyond what is captured in this assessment due to the wide range of energy-consuming process and equipment types. Utilities typically acquire these savings through custom projects at individual industrial sites.
