China kicked off construction on an ultra-high voltage (UHV) power transmission project on June 29 in order to transmit electricity generated in coal-rich Shanxi province to the eastern city of Nanjing, local media reported.The 1,119 Km 800 KV DC line will start from the Jinbei substation in Shuozhou City of northern Shanxi and reach Nanjing substation in Jiangsu’s Huaian City. Investment in the project is estimated at 16.2 billion yuan ($2.65 billion).The project gained approval from the National Development and Reform Commission in June this year and is expected to come into operation in 2017.Upon completion, Shanxi is expected to transmit 45 TW of electricity or equivalent of 20.16 million tonnes of coal per annum to eastern China.Jiangsu’s power consumption ranked the first in China over January-May. Total outsourced power accounted for 12% of its power consumption during the same period.Presently, total installed capacity of coal-fired and wind power in Shanxi have reached 55 GW and 5GW, with around 90% wind power at northern and central parts of the province.It is predicted that northern Shanxi’s newly-added installed capacity of coal-fired and non-coal-fired power would reach 15 GW and 7.8 GW during 2015-2020.Shanxi is the first province that implemented UHV project in China. On January 6, 2009, the world’s first 1,000 KV UHV AC demonstration project from southeastern Shanxi to Jingmen in Hubei province came on stream. In the past 6 years, over 50 TWh electricity or 23 million tonnes of coal was transmitted by the line to central provinces.By now, China has completed three AC and four DC UHV projects, along with four AC and three DC UHV projects under construction. Total power transmission volume has exceeded 330 TWh.
