The autumn schedule for power grid maintenance in Harbin, Northeast China’s Heilongjiang province concluded on Oct 30, according to information released by Harbin Electricity Co, a subsidiary of State Grid.

The maintenance program focused on the power grid in the downtown area of Harbin, as well as its eight districts and cities. It aims to guarantee electrical safety and support construction of high-speed railway lines in the area.

Harbin Electricity Co is responsible for the operation and maintenance of 103 substations and 20 power lines, according to Chen Tie, the company’s vice-president.

The heavy grid load was the biggest challenge to carrying out maintenance this year, Chen said.

During the autumn schedule, 13,729 staff members of Harbin Electricity Co participated in power grid maintenance and carried out 125 maintenance tasks. This year’s work represented a 54 percent increase compared with the same period in 2017.

The maintenance program started on Sept 1 and concluded on Oct 30, running through a 60-day period.

Harbin Electricity Co is committed to providing better electricity services for central heating and important winter tourism activities in Harbin, Chen added.
