Implementation Plan

GMP Smart Power is here. Now we are going to make it even smarter.

We've been hard at work bringing GMP Smart Power online for you. Now that we have fully implemented the first part of the upgrade, you'll start to notice a few changes, like our new online portal that allows you to view much more detailed information about your energy use. As we continue to make updates to GMP Smart Power, you'll have even more opportunities to be more efficient and lower your energy bill.
