【 摘 要 】

Customers with onsite generation typically remain connected with the grid to meet electrical needs that exceed the capacity of their DG facilities and to ensure, through diversity of supply, the reliability of their electric service in the event that their units are not available because of maintenance or some other reason. Grid-supplied service to these partial requirements customers comes in many forms--standby (or backup), scheduled maintenance, and supplemental--and, as the deployment of DG systems has increased, the urgency of resolving the difficult questions about their rates and rate structures has become more acute. What does it cost the electric system to provide standby service for partial-requirements customers, and how should these costs be recovered. What are the benefits of DG to the system. How should standby rates be designed to reflect these benefits and encourage customers to maximize the value of DG for themselves and the system. The decisions made today will have long-term strategic consequences.
