China's State Electricity Regulatory Commission (SERC) has activated first-class emergency response, promising all-out efforts to restore power supply disrupted by a 7.8-magnitude earthquake rocking southwestern China's Sichuan Province, the worst in more than two decades.

The earthquake in Wenchuan County, 159 kilometers northwest of the Sichuan provincial capital of Chengdu, as its epicenter, disrupted the electricity supply in central and northwestern regions, SERC sources said.
