Heilongjiang outbound power transmission reaches 2.4 TWh in Jan-Nov

2017-12-06 16:42:00 General,  Production & Sales sxcoal.com

Northeastern China's Heilongjiang province transmitted 2.4 TWh of electricity to other provinces in the past 11 months, accounting for 2.8% of its total power output, said the State Grid Heilongjiang Electric Power Company.


The outbound transmission was equivalent to the annual output of a 600-MW coal-fired plant.


In recent years, the province has been actively participated in market-based electricity trades and trans-provincial power sales, in a move to digest its surplus electricity and ease power shortfall in North and East China.


By the end of 2016, installed power generation capacity totaled 27.83 GW in the province, while more than doubling the maximum capacity the provincial grid can support, which was 10.85 GW.


As such, there has been a decline in utilization of power generating units in the province. In 2016, the province's coal-fired units utilization slid to 3,919 hours from 2010's 4,384 hours, and wind utilization dropped to 1,666 hours from 2,031 hours, much lower than the country's average of 4,165 hours and 1,742 hours in the year.


The rapid growth of clean power like wind and solar in the province intensifies the completion for grid access with thermal power.


Statistics showed the province wind installed capacity has grown to 5.68 GW for now, becoming the second biggest after thermal power, and solar capacity to 791.7 MW, surging 430% from a year ago.

The contradiction between large renewable installed capacity and limited capacity the gird can support hinders the clean power and causes wastes.


In 2017, the province's wind and thermal power plants participated in nine outbound power trades, signing a total 6.28 TWh of power supply contracts with Liaoning, Shandong, Beijing and provinces in northern China.


Heilongjiang also arranged 96 trans-regional spot market trades of surplus wind power between local wind power companies and end users over January-November, sending 140 GWh of surplus power to Hebei, Shandong and other provinces.


It's reported that a ±500 KV DC power transmission line connecting Qiqihar of Heilongjiang and Xing'an of Inner Mongolia is set to come online in the first quarter next year. It can add 2 GW of outbound power delivery capacity for the province.
