Chair, CIGRE 2023 Sendai Colloquium Organizing Committee

We are pleased to inform you that the CIGRE 2023 Sendai Colloquium will be held at
the Sendai International Center (Sendai, Japan) from October 3 to October 7, 2023.
This colloquium is organized by the Study Committee (SC) of CIGRE, an internationalorganization, and is held every two years. The colloquium is a meeting for thepresentation of CIGRE papers.
The colloquium is organized under the general theme of “Recent Overhead
Transmission Line Technologies and Environmental Measures” and is based on thepreferential subjects of “Sustainable OHL, Environment and Planning”, “Reliability of
OHL, Advanced Construction and Maintenance”, “Resilience of OHL, Recent
Technologies for Disaster Recovery”, from SCB2 (Overhead Lines), SCC3 (Power
System Environmental Performance) , SCC4 (Power System Technical Performance).
Over the three days, many papers will be presented in two tutorials and sevensessions. Social programs including receptions, a technical tour, and companion tours
are also
planned to contribute to international exchange.
Through the face-to-face CIGRE 2023 Sendai Colloquium, we hope to develop
opportunities to deepen information exchange and academic exchange with everyone
concerned and to contribute to the development of power technology around the world.
We hope that you will take note of the purpose and significance of this meeting, and wewould be grateful for your support.
We sincerely wish your company's continued growth and success in the future.
We look forward to seeing you in Sendai !

NGN initiatives in each country
Ms. Kerstin Weindl, Austria
After studying “Energy supply and sustainable development” Kerstin Weindl started
working at Austrian Power Grid in 2019. Kerstin works in Asset Management andsupervises a variety of projects. Projects range from maintenance projects regarding
Aging Assets to research projects such as climate change adaption projects. As a young
engineer, Kerstin is part of the Next Generation Network Austria, supporting andconnecting students and other young professionals in the industry.

Mr. Bingxiang (Bing) Lin, Australia
Bing is a civil and structural engineer in the transmission line industry, graduated from the
University of Adelaide in 2011. Bing worked in the transmission line utility named
ElectraNet for the first six years and have been working in consultancy firms since then.
Bing was the panel NGN liaison for APB2 (Australian panel on Overhead Lines) during
2015-2017 and the CIGRE Australia NGN Co-chair between 2018-2021. Bing is currently
the working group member for B2.81 “Increasing the Strength Capacity of Existing
Overhead Transmission Line Structures”, and the working group convenor for B2.85‘Emergency Restoration System for Overhead Lines – Guide for Design, Planning andInstallation”.

Ms. Kristine Engel, United States
Kristine Engel leads Solutions Engineering at LineVision where she applies her expertiseand technical insights for advancements in real-time conductor monitoring. Kristine started
her career as a field engineer in the oil industry and later built her expertise as atransmission line design engineer. Kristine has a Bachelor's in Mechanical Engineeringand a Master's in Sustainable Systems Engineering from the University of Wisconsin Madison. She is a registered Professional Engineer in Wisconsin, Vice Chair of the IEEE
Grid Enhancing Technologies Working Group, and International Collaboration Co-Chair for
the CIGRE USNC NGN.

Mr. Harish Krishnappa, Netherland
Harish Krishnappa received Master’s degree in “Electrical Power Engineering” from Delft
University of Technology, the Netherlands. He has 8 years of industry experience, working
at the TSOs in The Netherlands and India covering aspects related to grid operations(SCADA/EMS/ADMS), power system studies, electricity markets and national grid codedevelopments. He is currently active in the working groups of IEC TC57 (WG 13, 14 and16) and CIGRE SC-D2, covering topics related to power systems management andassociated information exchanges. Recently, he has taken the role of business productowner for CIMbion, a CIM conformity service on behalf of ENTSO-E. He has been actively
involved with CIGRE Netherlands since 2018.
