This guide provides comprehensive direction for the planning of new transmission, distribution, and generation substations as well as the expansion of existing facilities. The scope includes coordination with interconnecting facilities and has jurisdiction up to the point of interconnection. It supports both substation planning engineers and substation design engineers. This document provides a structured framework that supports the development of substation project scope for consistent substation designs. It provides a process for developing a substation project scope that enables adaptability to evolving standards, technologies, and various system needs. Key topics include: • Bus configurations to meet reliability and redundancy expectations • Initial versus ultimate design scope documentation for planning, for long term scalability • Property size requirements, including determination of both graded and fenced station area and external space • requirements • Grading strategies and site development considerations • Substation site selection guidelines and environmental factors • Coordination with transmission, distribution, and generation planning teams for system-wide alignment • Layout considerations for maintenance access, operational efficiency, and future expansions • Approaches to integrating new design standards into expansions of older or legacy substations • Coordination with interconnecting facilities for design and planning purposes.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
