Vancouver TALK 25: Grid-scale Gravity-based Electrical Energy Storage System

#talk #life

Speaker: Janos Toth, Vice President of Business Development, Gravient

The topics will include the following:

·        The need for grid scale (larger than 20 MWh) energy storage

·        Challenges with the current grid scale energy storage technologies (pumped hydro, compressed air, hydrogen, Lithium Ion and other chemical batteries)

·        Development of gravity based lifted weigh energy storage technology.

·        Gravity based lifted weight grid scale energy technology details.

·        Benefits of lifted weight energy storage technology

·        Status of implementation of lifted weight energy storage technology


Registration is optional, but we want to know who to expect.
10:00 AM P.D.T. You can log in at 9:45 AM (12:45 PM Montreal) to check connection and say hello.
All IEEE members are welcome, especially those Life Members that don't have a local Affinity Group.

We are looking for speakers for the rest of the year, contact Carl Zanon <> if interested.

Janos Toth


Grid-scale Gravity-based Electrical Energy Storage System


Janos holds a Master’s degree in Civil Engineering from Hungary and a Ph.D. degree in Civil Engineering with minors in Engineering Mechanics and Space Engineering from the University of Arizona, USA. Additionally, he is certified as a Project Management Professional (PMP) and a Professional Engineer (P. Eng. and P.E.) in both Canada and the United States.

In his earlier career, he served as a transmission line asset manager at British Columbia Transmission Corporation (BCTC), where he was responsible for all civil/structural aspects of 18,000 km of transmission lines and 300 substations for the British Columbia.  Subsequently, he managed the Research and Development program for BCTC and, after the merger, at BC Hydro. His activities included representing BC Hydro at various associations, forums, and conferences in the electrical energy storage area.

Janos held the position of Vice President of Engineering at Quanta Energized Services, a subsidiary of Quanta (#244 on the Fortune 500 companies list), with a focus on live (energized) line work.

He founded his engineering consulting company in 2003, undertaking a wide variety of engineering consulting projects globally. Janos has successfully completed projects in Canada, the US, Iceland, Sweden, Norway, Australia, China, Moldova, Georgia, the Middle East, India, Japan and Hungary.

He is the founder and CEO of RecognAIse Technologies a high tech company using Artificial Intelligence for transmission line visual inspections.

He has been an active member of several national and international standard committees, including the Institute of Electrical and Electronics Engineers (IEEE) Power Engineering Society (PES) and The International Council on Large Electric Systems (CIGRE).

His latest interest focuses on the commercialization and integration of grid scale energy storage technologies into the electric grid.
