Shortly after the Wenchuan Earthquake of M8.0, State Power Economic Research Institute (SPERI) undertakes an intensive investigation on the damages on the Sichuan power grid. This paper, based upon the investigation, presents causes of the damages on the grid framework including the transmission facilities and buildings, and it also brings forward a preliminary conclusion. Aiming at enhancing the anti-earthquake capacity of the power grid at the planning and design stages, the paper proposes some concrete measures and suggestions on the technical standards for power grid construction, quick recovery, reconstruction planning, electric installation and substation building construction, and so on.
