ISLAMABAD, Nov 1 (Gwadar Pro) - Two units of the Thar Coal Power project have successfully reversed power transmission on the first run, as per a Facebook statement by Shanghai Electric on Monday.

“As a result, each section was nominally powered, and all instruments and signal indications were accurate”, the statement said.

Shanghai Electric is the sponsor of a 7.8 million tons per annum coal mine and the integrated 1,320 megawatts mine-mouth power plant projects in Block-I of Thar Coal field in Sindh province.

Reverse power transmission refers to the initial tests a power plant goes through before commissioning to examine that the installed machinery runs safely on electric power provided by the national grid (back energisation), according to experts.

Gwadar Pro learned that the power plant is at advanced stages of completion and currently undergoing various tests as per Schedule 8 of the Power Purchase Agreement (PPA). For this purpose, the plant was back energised on October 13 by connecting it with the national grid. The plant is going through 8.2 set of tests, which are required before synchronisation with the national grid. These tests will be followed by 8.3 tests upon synchronisation and post-synchronisation, after which the final pre-commissioning tests will be carried out.

The power plant, upon completion, will provide affordable electricity to four million households in Pakistan.

“We look forward to the day when the whole set of units activated and  connected to the grid”, Shanghai Electric said in the statement.
