I have been considering purchasing a ELITEpro portable power datalogger.  This logger would let me know what each peice of equipment is using in KWH's

By knowing what each dryer, thermolator, and hydraulic molding machine is costing to opertate in electricity I am hopping I can determing if newer equipment can reduce our electric usage and what the payback would be for using new equipment that cost less to run. This information should also give us more accurate figures in quoting product.

I also think if I can show electric molding machines to be cheaper to run than hydraulic machines than our demand charge may go down since we would not havt to start machines up to let warm up.

Has anybody done anything like this in the past and if so to what success?

Does anybody have a kwh meter that they use and if you do, do you like/dislike it?

How can I "justify" the cost of a tool that may or may not help us?

Jason,
We have used a power meter supplied by Hoosier Energy in the past to monitor issues that we had.  Contact your power supplier and they should be able to get you some short term help that will help you find out whether it is worthwhile over the long run to invest in one.

Our electric company is Rush Shelby.  I think they buy their power from Hoosier Eneregy.  I have a contact name of Mike Walker for Hoosier Energy.  I will give him a call. 

Have you done anything to reduce your demand charge?

I have installed a capacitor bank to bring our power factor to 100% so we do not get charged a penalty for a poor power factor, but I would like to continue saving money by reducing our demand charge as well.  Any suggestions?

I would ask your local electric company to come in and do an energy audit.  Again this is through Hoosier Energy.  We have altered the startup times of our machines to avoid demand charges and we have always used power factor correction as well. Some preventative measures as well that can be used in clude a thermal image camera that can show you your hot spots as well as review your breakers and main motors for poor connections.  These will cost you money as well as cost you downtime and equipment if not corrected.
