Transmission and Substations

Program 34, 35, 36, 37, HVDC, EPRI|U for Transmission, CIIG, and TSC

Transmission and Substations (T&S) area aims to address the challenges facing transmission asset owners and operators. The area is focused on transmission (overhead and underground) and substation assets, their life cycle, and industry issues. This site provides participants a way to interact with research results and stay involved with on-going projects.

PROGRAMS


Transmission Asset Management Analytics

Program 34 provides utilities with new knowledge, algorithms, analytical methodologies, and data vital for making good asset lifecycle management decisions amid challenges posed by aging infrastructure, financial constraints, and retiring expertise.


Overhead Transmission

Program 35 offers a portfolio of tools and information focused on components (such as conductors, insulators, switches, connectors, and structures) and system issues (such as lightning and grounding, line design, live working, transmission capacity, and high-voltage direct -current [HVDC] lines).

Underground Transmission

Program 36 intends to assist utilities in resolving challenges related to design, construction, installation, operation, and maintenance of underground transmission systems.

Substations

Program 37 is designed to address the challenges faced by substation asset owners and operators. A significant portion of substation equipment was installed many years ago and may be reaching the end of its service life.

High Voltage Direct Current (HVDC)

Projects- P35.019- HVDC Lines and P37.116- HVDC Converter Stations and Flexible Alternating Current Transmission System (FACTS) Devices

EPRI U for Transmission

EPRI U for Transmission provides high-quality, foundational technical training for utility engineers and other transmission staff that work in assets, asset management, operations, and planning


Contaminated Insulation Interest Group (CIIG)

The CIIG is intended to be a forum where T&D asset owners can regularly engage with one another and world experts on the topic of contaminated external high voltage insulation.


EPRI Transmission Sector Council (TSC)

The Energy Delivery and Customer Solutions (ED&CS, formerly called PDU) Sector Council is comprised of executives from member utilities across the four Subsector Councils - Transmission, Distribution, Information, Communication and Cyber Security, and Electrification & Sustainable Energy Strategy.
