The U.S. Department of Energy (DOE) amended energy conservation standards for certain commercial and industrial electric motors, under subpart B of Title 10 of the Code of Federal Regulations, Part 431, including a number of different groups of electric motors that DOE has not previously regulated. For those groups of electric motors currently regulated, the proposed standards would maintain the current energy conservation standards for some electric motor types and amend the energy conservation standards for other electric motor types.
DOE’s analyses indicate that the proposed standards would save a significant amount of energy. Estimated lifetime savings for electric motors purchased over the 30-year period that begins in the year of compliance with new and amended standards (2015–2044) would amount to 7.0 quads (full-fuel-cycle energy). This is equivalent to 30 percent of total U.S. industrial primary energy consumption in 2011.
The estimated cumulative net present value (NPV) of total consumer costs and savings attributed to the proposed standards for electric motors ranges from 8.7 billion (at a 7-percent discount rate) to $23.3 billion (at a 3-percent discount rate).
