In Japan in March 2011, an earthquake, a tsunami and the subsequent accident at the Fukushima Nuclear Power Station caused a severe power crisis in the country. In the immediate aftermath, some prefectures responded with rolling blackouts. The government started encouraging companies and residents to conserve electricity (by adopting self-restriction plans), especially during the summer months of 2011. The major contribution of this study is to examine the effects of the disaster, power blackouts, and self-restriction plans on the magnitude and pattern of load demand. Such an analysis is needed to develop an effective energy policy. The effects of day of the week, holidays and temperature on load demand are estimated and compared before and after the disaster. The study also examines the effectiveness of the voluntary electricity saving plans and addresses what can be learned from a sudden energy crisis. The results show that total demand decreased after the disaster and it is shifted from weekdays to weekends and holidays. In addition the impact of temperature on load demand changed after the disaster.
