SUPCON SOLAR Delingha 50MW CSP Plant Set New High of Single-day Electricity Output

2019.06.13     From: SUPCON SOLAR

From June 12th to 2:12 am June 13th, SUPCON SOLAR Delingha 50MW Tower CSP Plant has generated 863MWh electricity, setting new high of single-day output.


The operation record of June 12th shows the molten salt temperature at receiver outlet reached 566℃(The design value is 565℃). At 5:40 pm, the hot salt tank has been fully filled and the average molten salt temperature was 563.2℃. The main steam reached 541℃/13.3 MPa(The design value is 540℃/13.2MPa), and the output power of generator reached 50.61MW (The design value is 50MW). As of 2:12 am June 13th, when the plant was desynchronized to the grid, the total electricity output is 863MWh, which accounted for 96.5% of the predicted electricity output of 894MWh based on the performance model.
