Q: I have a question regarding the choice of option A or option B. In my project, I will not directly measure all forces on the equipment, but I can calculate indirectly through engineering theories. The project involves the exchange of a mineral oil for a synthetic one in a reducer of a steel plate laminator. I'm not going to measure the forces directly on the laminating rollers, but by the reduction and material, I can calculate. The electric current will be measured directly in the electric motor. In a case like this, should I select option A or option B?

Another question is whether you certify/approve/review a project like this (obviously following the IPMVP to the letter) and how I apply it.

A: Based on the information provided, this appears to be an Option A. As described, if the motor kW is the one and only energy parameter, measuring kW of the motor pre and post exchange of the mineral oil, this could be considered an Option B under the following conditions:

- True kW needs to be the measured parameter instead of amps.
- One approach would be to measure the energy (kW and kWh) of the process utilizing the existing mineral oil (baseline condition under an appropriate time period to capture operating conditions) and then measure the energy post-retrofit to the new synthetic oil. Another critical variable to define is the load on the system - and verifying that it is a constant load pre and post.
- The M&V Plan should clearly describe how this oil replacement will save energy, confirming that the energy is represented at the motor and document other variables that can impact such as the load and what the other forces on the equipment are.
