Guangdong and Macao boost interconnection

The power supply network between Guangdong and Macao has been upgraded from a 110kV double-circuit to 220kV triple-circuit. It could be further upgraded to 110kV quadruple-circuit for emergency use.

This was announced by Franklin Willemyns, CEM Chief Executive Officer during a meeting between leaders of both CEM and Guangdong Power Grid Corporation to discuss issues concerning power supply, power grid operation, and power grid construction.

The network was integrated in 1984.

By the end of 2011, a 220kV double-circuit interconnection will be built from Qinyun Station in Zhuhai to Lotus Station in Macao, a facility expected to further boost power supply capacity between the two regions. He counted on the continuous cooperation and support from Guangdong Power Grid to provide reliable and stable supply at reasonable prices.

Guangdong and Macao have established a set of cooperation mechanisms regarding power interconnection. Both sides have formed interconnection work groups, interconnection operation groups and project coordination groups, as well as periodically holding meetings for better coordination.

Franklin Willemyns also said that since Macao returned to China, it has experienced dramatic social change and rapid economic growth. At the same time, its power demand has continually grown over the years, making it more dependent on power supply from Guangdong. In 2009, power consumption in Macao totaled 3,653 billion kWh, and 61 percent or 2,227 billion kWh was purchased from Guangdong.

Guangdong Power Grid Corporation Deputy General Manager Liao Jian Ping stated that according to spirit of the “Electricity Cooperation Framework Agreement 2010-2020 between China Southern Power Grid and the Macao SAR Government", GPG will continue to strengthen cooperation with CEM and welcomed the Power Service Seminar to be held in Zhaoqing for further implement discussion on power operation and management as well as clean power transmission.
