City plans smart grid for power

By Ni Yinbin | April 21, 2010, Wednesday | Print Edition

SHANGHAI will build a smart grid system in the next few years, a delivery system that experts said would help secure the city's power supply while providing cleaner energy.

The National Grid plans to construct the smart grid system in Shanghai after the World Expo, officials said at a forum yesterday.

Shanghai Electric Power Co Ltd, the city's power supplier, said it will take five years to build the smart grid and another five years to upgrade it.

"The program is still in the trial phase," an official of the company said yesterday.

A smart grid is a system that keeps track of all the electricity flowing through it. It often uses two-way digital technology to control appliances at consumers' homes to save energy.

The technology has been used in some city utilities, such as the new underground transformer station on Mengzi Road near the World Expo site in Puxi.
