According to the National Energy Administration, in order to enhance the ability of inter-provincial emergency coordination and do a good job in dealing with power emergencies during important periods such as meeting the peak and spending the summer, on 15 June, the State Energy Administration held an emergency drill for large-scale inter-provincial blackouts in East China, which was a complete success. This is the first time that the National Energy Administration has held an emergency drill for large-scale power outages across provinces, and it is also a joint emergency exercise carried out so far on the largest scale, the widest scope and the most targeted for power emergencies.
