Energy Savings Potential | It has been reported that replacing an existing rotor with a new rotor that is optimized for power consumption reduces the rotor motor electricity consumption by 10 to 30%. |
CO2 Emission Reduction Potential | |
Costs | Projected annual monetory savings in the Canadian mill due to reduced electricity consumption amounts to $193,000 (2006 dollars) (Kramer et al., 2009. p.97). |
