Northwest Energy Efficiency Alliance (NEEA) funded the Drive Power Initiative (DPI) between 1999 and 2004. The DPI encouraged motor service centers in the Northwest region (including Idaho, Montana, Oregon and Washington) to adopt green motor rewind practices to reduce energy use for motors used in the agricultural and industrial sectors.
Since 2004, NEEA has conducted long term monitoring and tracking studies to assess the impact of that initiative. In this 2015 update to the key Alliance Cost Effectiveness model assumptions for motor rewinds, we find that green motor rewinds have not yet become standard practice in the Northwest.
Green Motor Practices Group members reported that green motor rewinds comprised only 33 percent of all horsepower rewound, and 24 percent of member respondents performed no green motor rewinds in 2015. Only one nonmember reported performing green motor rewinds. Furthermore, the estimated number of rewinds performed by Northwest motor service centers decreased each year from 2013 and 2015 from 4,631 in 2013 to 3,059 in 2015, indicating a decline in the motor rewind industry.
