This guideline establishes criteria and requirements for the interconnection of distributed resources within the distribution system of EPCOR Distribution & Transmission Inc. (EDTI). Specifically, this guideline defines the technical requirements for connecting generation that is not exclusively owned by EDTI, but is connected to EDTI facilities, with an operating voltage of 25,000 volts (25 kV) or lower. Requirements relevant to the safety, performance, operation, testing and maintenance of the interconnection are provided.
The requirements established in this document cover a broad spectrum of interests. The addition of distributed resources to the distribution system may change the system and its response. Attaining a technically sound, strong and safe interconnection among distributed resources and the distribution system mandates diligence on the part of everyone involved in the interconnection. The requirements in this guideline need to be cooperatively understood and met among everyone involved in the interconnection including designers, manufacturers, users, owners and operators of both distributed resources and distribution systems.
This guideline has been developed with reference to international standards such as the Institute of Electrical and Electronic Engineers (IEEE) standard P1547, DRAFT Standard for Interconnecting Distributed Resources with Electric Power Systems.
This document does not constitute a design handbook. Power Producers who are considering the development of a generation facility intended for connection to EDTI’s distribution system should engage the services of a professional engineer or a registered consulting firm qualified to provide design and consulting services for electrical interconnection facilities.
