According to the statistics of Ningbo Customs, 298 generators worth US $ 9.9144 million were imported in the first half of this year at Ningbo Port, up 15 times and 3 times over the same period of last year. As temperature is soaring, the shortage of electricity is more and more critical. Therefore, it is necessary to partially cut supplies or impose curbs on power consumption. But, it is difficult to buy domestic generators in domestic market. Some foreign trade enterprises must buy imported generators in order to meet their demand for electricity.
