* Higher-than-usual growth due to demand, low base figure
* Official power consumption data due next week (Adds details)
In November, China's power consumption increased 27.6 percent year on year.
The higher-than-usual growth was likely due to recovering electricity demand and a weak base figure a year earlier when demand slumped because of the economic slowdown.
China's National Energy Administration is expected to release official power consumption data next week.
The report said State Grid Corp aimed to build four ultra-high voltage (UHV) power lines by 2012 with a transmission capacity of 50 gigawatts to carry power produced at coal-fired generators in Shanxi, Shaanxi and the western part of Inner Mongolia and wind power from Hebei, to Beijing, Tianjin and neighbouring regions, the report said.
The UHV lines would also bring power from hydropower-rich southwestern China to east and central China, it said.
