The Office of Regulatory Staff, with guidance and feedback from the electrical utilities and other interested parties, shall investigate and report to the Public Service Commission on fixed costs, fixed charges, and the extent of cost shifting that is attributable to distributed energy resources within current utility cost of service ratemaking methodologies, cost allocations, and rate designs, with a focus on the implications distributed energy resources could have for that business model in the future. The report shall review how to ensure a fair allocation of costs and benefits between consumers who utilize distributed energy resources and consumers who do not utilize distributed energy resources, as well as suggesting any necessary or prudent changes to existing or future rate structures. The report shall include a general overview of cost shifting that is attributable to or arising from historical cost of service ratemaking related to the current utility business model, specifically the cost of service ratemaking methodology, the cost allocations and rate designs. The findings shall include public comment and be reported to the Public Service Commission by December 31, 2015.
