In 2003 the Shanghai electric power company " the security civilization production " reaches the sign unit, 2003 - 2004 Shanghai electric power company safety in production advanced unit, 2001 - 2002, 2003 - 2004 Shanghai civilized unit. In 2004 national electrical network company first-class county power supply enterprise. Company existing 220 ThousandVolt (110 kilovolts) transformer substation 1, 35 kilovolts transformer substations 5, Main transformer 9, the aggregate capacity 318300000 volt-amperes, match change 442, two islands existing 35 kilovolts transmission lines 11, always long 61 kilometers. 10 kilovolts overhead lines 25, always the long 263 kilometers, 400 volts lines 1500 kilometers, two islands pooled sizes user 30000 extra households, the total attire meets the capacity 8.51000 volt-amperes. The electrical network supplies power by the Shanghai Changxing Island second power plant two 1.2 megawatt power sets and the Ch'ung-ming - Changxing Island 35 kilovolts submarine cables. The lasted 4 years " two turn " the village electrical network transforms 1999 to 2003, the Shanghai electric power company invests 155000000 Yuan, newly built 35 kilovolts transformer substations 3; Increases 35 kilovolts lines 45 kilometers; The new increase transforms 10 kilovolts lines 152 kilometers. And constructed long is popular - between the horizontal sand two islands 35 kilovolts greatly surmounts the transmission line (designs 110 kilovolts), fundamentally solved the power supply not reliable problem which the horizontal sand island because the under-sea cable breakdown created. Along with Shanghai, honored, the Soviet more river big channel construction, the Chiangnan shipyard, center the sea group and so on the big user settles down Changxing Island to the electric power need, the Shanghai electric power company invests again in Changxing Island constructs one 220 kilovolts long is popular the transformer substation and the Jiangsu Nantong - Ch'ung-ming - long is popular 110 kilovolt long horizontal power supply project, in April, 2005 was completed throws transports. At present supplies power reliably rate 99.77%, voltage qualified rate 98.16%.
