    Assistance in sizing XFMR

    The "Running Mode KVA Eq" looks like a good estimate of running load. Two of these equals 2 x 133 kva = 266 kva. All of the other misc load will run around 20 kva. A 300 kva 3-phase transformer would handle the running load, but I would chose a 500 kva transformer to handle the running load...

    Smart Grid

    Power companies are no longer run by engineers. Accountants, lawyers, and Women's Studies grads are now in charge. That explains why the Smart Grid is so exciting to everyone except those of us who still know what the hell is going on.

    Utilization of Electrical Energy in a large Industrial pharmaceutical

    Call the power company. They probably have an industrial engineer or an ee who works with their industrial customers. He will be familiar with the electric rates. He can probably meet with you and give you some good ideas.
