Global Experts to Convene in Beijing to Lay Roadmaps for Ultra High Voltage Technology

New York, Apr 10, 2007

In nations such as Brazil, China, and India, governments are faced with the challenge of supplying densely populated urban centers with power from remote generating stations in an efficient and environmentally responsible manner. In places where electric demand is growing but room for transmission lines is limited, a new technology known as ultra high voltage, or UHV, offers an important viable solution.

Delivering voltages of 1,000 kV alternating current or higher and a minimum of 800kV direct current, UHV technology can carry large quantities of electricity long distances over a single power line corridor and with minimal loss of power. International Standards for this emerging technology have yet to be developed.

On July 18-21, 2007, in Beijing, China, the International Electrotechnical Commission (IEC) and CIGRE (the International Council on Large Electric Systems) will host the International Symposium on International Standards for Ultra High Voltage. The event will bring together global experts to lay the plans necessary to support this new technology and its potential applications.

Through panel discussions led by major international players, the conference will explore research and projects in progress around the globe; technical challenges relating to systems planning and equipment design; as well as testing, regulatory and standardization issues.

The symposium offers an opportunity for U.S. stakeholders to become engaged early on in the process and influence international UHV standardization efforts at the ground level. The conference is open to all interested stakeholders, including planners and operators of utilities and transmission systems, contractors, equipment manufacturers, transmission design engineers, researchers, and members of government and academia.

A preliminary program for the event can be found here. For further information and registration details, please contact Antoinette Pitteloud, IEC/CIGRE UHV symposium coordinator (; +41 22 919 02 35) or visit

As the U.S. representative to the IEC, the United States National Committee (USNC) supports the development, dissemination, and use of electrotechnical standards. The committee’s scope spans all electrotechnologies, including electronics, electroacoustics, telecommunication, and energy production and distribution.
