Electric Transmission

Wednesday, April 19

10:00 AM – 11:30 AM
Learning from Major Transmission Failures
Speakers: Julie Barton-Smith, Communications Manager, Bonneville Power Administration
Brian Low, Civil T-Line Engineering Supervisor, Pacific Gas and Electric Company
Steve Zubiri, Work Methods & Procedures Supvisor, Pacific Gas and Electric Company
Bonneville Power Administration will showcase a series of fiber optic failures installed on high voltage transmission lines in the past 20 years. This session will detail failure trends, life cycles, and asset plans based on causal analysis of failure events on the BPA system. Additionally, Pacific Gas and Electric Co will provide an in depth look at the failure of a recently installed 230kV G95 Tower. This session will detail the series of events that led to this failure, summary of the root and contributing causes, and an overview of the efforts underway to mitigate the potential for reoccurrence.

3:30 PM – 5:00 PM
Grid Changes Due to Load Flow Dynamics
Speakers: Neil Millar, Executive Director of Infrastructure Development, California Independent System Operator
Branden Sudduth, Director, Transmission Expansion Planning Department, Western Electric Coordinating Council
California recently increased its renewable portfolio standard to require that retail sellers of electricity and all electric utilities to procure 50% of their energy from qualified renewable resources by 2030.  In addition, several large base load coal and nuclear plants closed in recent years and many more are expected over the next ten years.  The gradual shift away from large base load thermal plants to a greater reliance on renewable resources will have a profound effect of the operation and planning of the western electricity grid.  Neil Millar, Executive Director of Infrastructure Development, California Independent System Operator and Brandon Sudduth, Director, Transmission Expansion Planning Department, Western Electric Coordinating Council will lead an insightful discussion of how the transition to renewable resources will affect the operation and planning of the Western US high voltage transmission system.

Not In My Backyard
Speakers: Jens Nedrud, Senior Project Manager, Puget Sound Energy
Keri Pravitz, Community Projects Manager, Puget Sound Energy
Mike Staats, Manager of Transmission Engineering, Bonneville Power Administration
Construction of the Big Eddy-Knight 500-kV high-voltage transmission line posed many challenges and opportunities including sensitive environments with cultural resources and a tight timeline. Solid and healthy relationships with partnering tribes were required all while considering the public and BPA’s customers keen interest in the planning and outcome of this project. Puget Sound Energy’s Energize Eastside Community Projects Manager, Keri Pravitz, will present on the PSE’s approach to customer engagement for their project to construct a new substation and upgrade approximately 18 miles of 230kv transmission lines, describing their Community Advisory Group process, open houses, neighborhood meetings, city council briefings, an EIS process and individual property owner conversations on project need, routing, pole locations, EMF, alternative solutions, and other issues. Come hear about PSE’s extensive outreach campaign for transmission siting.

1:00 PM – 2:30 PM
Leveraging Technology: Aerial Data Collection, Smart Grid Solutions, and SmartWires
Speakers: Chris McMurty, Solutions Architect, Sharper Shape Inc.
Dr. Subramanian Vidari, President, Modern Grid Solutions
Gregg Rotenberg, President, Smart Wires
Andee McCoy, Director of Customer Success, Smart Wires
Utilities implementation of Unmanned Aerial Systems (UAS’) has blown the doors wide open to opportunity for data acquisition. This program will explore the mountains of data available for transmission asset analysis and tools used today to process the data for everyday solutions. Grid operators understand that the demands on the electric system are changing faster than ever and are seeking more agile and flexible tools to add to their tool belts. Learn about proven modular, scalable, and re-deployable power flow control solutions that are available today and how they are changing the way utilities plan, build, and operate their grids.
