Interconnection of Distributed Generation to Utility Systems - Latest Publication from RAP

States have jurisdiction over most interconnections of distributed generation to utility systems in the U.S. While a majority of states have established interconnection regulations, they tend to focus on the smallest systems. This paper provides recommendations for state interconnection rules for distributed generation in the 10- to 20-megawatt range. It covers technical requirements, procedures and agreements to preserve the safety, reliability, and service quality of electric power systems and make interconnection as predictable, timely, and reasonably priced as possible. Emerging interconnection issues that states will need to address in the future also are covered, including high penetration of distributed generation, advances in technology, and screening criteria that set interconnection study requirements.
