The First Upgraded Unit in 2018 with Expanded Capacity at Gezhouba Power Station was Connected to Power Grid

After maintenance and upgrading, the No.4 power generating unit at Gezhouba station successfully passed the 72-hour trial operation with sound performance indicators (vibration, run-off, temperature rise, etc.) and stable operations, and went online for commercial operation. This concludes the 188-day upgrading and capacity-expansion efforts of the unit.
　　
No.8 and No.21 units of Gezhouba Power Station are scheduled to undergo a post-maintenance trial run on May 24 and June 1, respectively. By then, the annual overhauling will come to a successful completion, underpinning the safe and stable operation and larger-capacity power generation of the units during the flooding period.
　　
Since the upgrading project of the 19 125,000 kW units in Gezhouba Power Station started in 2012, the upgrading of the water turbines of all units, generators of the 8 units and 14 main transformers (including 2 standby transformers) have been completed. Based on the plan, the upgrading and capacity expansion project of the Gezhouba Power Station will be completed in 2021, upon which the cumulative capacity of units will increase by 475,000 kilowatts. That will further increase the utilization rate of the water energy in the Yangtze River and provide more clean energy for the society.
