The electric company for our school project offers a rate structure which includes a lower rate for heat pumps. About 2/3 of the building will be served by heat pumps, so we would like to take advantage of this. The rate only applys to the heat pumps themselves, they need to be metered separately. We would like to include this in our energy model, because it provides more advantage over the baseline, which is packaged VAV with hot water reheat.

Our concern is the PRM guidelines say the same rates need to be used for the baseline and proposed buildings. Has anyone had experience with a similar rate structure?
