Active Standards
IEEE PES Standards Process
Many of the PES Technical Committees and their Subcommittees create and maintain standardization documents related to the Committee scope of activity. There are three types of standardization document: Standard, Recommended Practice and Guide. These three types of document are generically referred to as “IEEE Standards”.
The American National Standard document development process is based on the American National Standards Institute (ANSI) Essential Requirements for openness, balance, consensus and due process. The IEEE Standards Association (IEEE-SA) oversees the IEEE standards development process.
The IEEE-SA Standards Development OnLine, SDOL, provides a step-by-step description of the IEEE standards development process, including forms and tools. Standards projects are started in the IEEE-SA with the approval of a PAR (Project Authorization Request). PARs define the sponsor, scope, purpose, and contact points for the document project. In the IEEE-SA list of active PARs all those with a sponsor code starting with PE/ are PES Technical Committees document projects.
There are two methods of participating in document development. First is to become a member of the PES Technical Committee group developing the document. The second approach is to join the document balloting pool. The cost of balloting pool membership depends on if the applicant already has membership to the IEEE or an IEEE society.

Standard Number: IEEE 1264 – 2022: IEEE Guide For Animal Mitigation for Electric Power Supply Substations
Standard Description: Documented in this guide are methods and designs to mitigate interruptions, equipment damage, and personnel safety issues resulting from animal intrusions into electric power supply substations, thereby improving reliability and safety, and minimizing the associated revenue loss.
Standard Number: IEEE 1366 – 2022: IEEE Guide For Electric Power Distribution Reliability Indices
Standard Description: Distribution reliability indices and factors that affect their calculations are defined in this guide. The indices are intended to apply to distribution systems, substations, circuits, and defined regions.
Standard Number: IEEE/ASHRAE 1635 – 2022: IEEE/ASHRAE Guide for the Ventilation and Thermal Management of Batteries for Stationary Applications
Standard Description: Vented lead-acid (VLA), valve-regulated lead-acid (VRLA), nickel-cadmium (Ni-Cd – both fully vented and partially-recombinant types), and Li-ion stationary battery installations are discussed in this guide, written to serve as a bridge between the electrical designer and the heating, ventilation, and air-conditioning (HVAC) designer. Ventilation of stationary battery installations is critical to improving battery life while reducing the hazards associated with hydrogen production (hydrogen production is not a concern with Li-ion under normal operating conditions [it is under thermal runaway conditions]). This guide describes battery operating modes and the hazards associated with each. It provides the HVAC designer with the information to provide a cost-effective ventilation solution.
