The hydel resource development in Pakistan takes a giant leap forward, as the third and the last unit of Tarbela 4th extension hydropower project was also synchronised with the national grid Saturday.
The third unit was operated on various loads up to 466 MW. With synchronisation of the third unit, the maximum contribution from Tarbela 4th extension hydropower project to the national grid reached to 1307 MW. Had there been ample water level in Tarbela Reservoir, the generation from Tarbela 4th extension hydropower project would have been reached to its maximum generation capacity of 1,410 MW. After conducting the load rejection test at 466 MW, the third unit has now been stopped for technical examination in accordance with the standard operating procedure.
Earlier, the first and the second unit of Tarbela 4th extension hydropower project restarted electricity generation on September 8 and 13 respectively after lifting of the draft tube gates by WAPDA engineers by their concerted efforts. Since commissioning, Tarbela 4th extension hydropower project has contributed 632 million units of low-cost electricity to the system during the test run.
