The 1,320-megawatt coal-fired power plant of the China Power Hub Generation Company (Pvt) Ltd (CPHGC), being constructed in Hub, Balochistan, has been partially energized and achieved interconnection with national grid, subsequently achieving back energization of its 500kV GIS from Jamshoro side of the transmission lines.
With this achievement, CPHGC has officially entered into hot commissioning phase of the complex that would lead to synchronization of its 1st Unit with the national grid in December, said a company announcement.
The process of power back-feeding was completed after a series of key steps such as line connection, site acceptance tests, high pressure test of GIS [gas-insulated switchgear], injection test and inter tripping test all witnessed by relevant regulatory authorities. The whole operation was completed safely and all the parameters of the relevant grid equipment were found within normal limits.
CPHGC has also achieved energisation of start-up transformer and 10kV auxiliary power system, and preparing for the system commissioning of Unit 1. The milestone was achieved in collaboration with the production and technology departments of CPHGC and National Transmission and Despatch Company.
