These systems, which are considered as “behind-the-meter” (BTM) systems, allow facilities to maximize the benefits of on-site renewable generation. BTM systems give facilities the option to reduce demand charges1 imposed by the utility and leverage time-of-use rates2 to lower. . Installing on-site renewable energy systems is a common strategy facility owners can use to save money, reduce their greenhouse gas emissions, and add resiliency to their facilities by generating their own electricity. Controlling your own energy supply means more predictable and reliable energy generation that lowers costs and environmental. . An On-site PPA involves the installation of renewable energy equipment—typically solar panels—directly on a business's premises. A third-party developer owns, operates, and maintains the equipment, while the business purchases the generated electricity at a fixed rate over a long-term contract.
