I talked about my facility having various motors in this thread: https://ask.itac.energy/t/how-do-i-improve-motors-that-are-wasting-energy-in-our-plant/54/1. While I am working on getting help from SJSU ITAC, I wanted to know how big of an impact could getting a better motor have on cost savings. We have couple of big motors.
I am happy to hear that you are in contact with ITAC. Upgrading motors having standard efficiency to premium efficiency can have a significant impact, especially when dealing with big motors. For example, for a 200 HP motor, upgrading to a motor with premium efficiency can lower cost by $3,800 annually (based on energy rate of $0.1/kWh).
I didn’t know it could have such a big impact. Can you suggest to me a resource which can have a simple rule of thumb for other energy efficiency measures related to motors?
DOE’s Better Plant program has a great Motor System info card: https://betterbuildingssolutioncenter.energy.gov/sites/default/files/attachments/BP_Motor%20Systems_Info%20Card_Final.pdf , which list various rule of thumb for approximate impact. However, ITAC can provide you with an accurate impact number from their energy efficiency assessment.
