Energy from the utility is sold as a bundled cost of the commodity (electricity) and transmission and distribution (“T&D” - the wires, poles, substations, and pipes). Onsite microgrids have no T&D costs while utility T&D costs, in the markets Unison Energy, serves, typically increase on average 3 – 12% per year. Because Unison Energy’s microgrids cover 80 – 95% of a customer's on-site energy costs, the utility T&D cost avoidance on the majority of our customer's electricity spend ensures that the savings from on-site generation increase over the term of the ESA.
