Distributed Generation Interconnection Studies

Distributed generation (DG) interconnections are not new in the utility industry; however, utilities have not necessarily been involved with a significant number of these interconnections to date. Power System Engineering, Inc. (PSE) recognizes that the number of requests utilities are receiving has been increasing over the past few years and will most likely continue to increase as the desire (or, in the case of some states, the requirement) to bring on new renewable energy resources increases. PSE can offer a proven team of senior staff consultants to assist with:

• Developing interconnection standards, technical requirements, and guidelines.
• Completing feasibility, system impact, and facility studies.
• Assisting with the implementation of solutions to facilitate the DG interconnection and parallel operation with the utility's distribution system.
• Assisting with inspection and testing of installed DG systems.
• Developing net metering and standby rate tariffs.

The interconnection of generation facilities with existing electric distribution systems requires a comprehensive and complete review to identify any adverse system impacts and the interconnection facilities required to accommodate the safe and reliable interconnection and operation of the generation facility. It is common to divide this review process into several steps (a feasibility study, a system impact study, and a facilities study) to provide the involved parties needed information at natural decision points along the way, such as whether to continue toward the implementation of a proposed project. In this manner, the review process becomes more manageable and efficient.
