Lahore, August 03, 2015 (PPI-OT): The Pakistan Water and Power Development Authority (WAPDA) hydel power stations delivered as many as 4.434 billion units of low-cost hydel electricity to the National Grid in July 2015. This is the highest-ever generation of hydel electricity in one month, and constitutes about 41 per cent of the total electricity, the country’s system received from all sources. This was told in a meeting of the Authority held here at WAPDA House today.
WAPDA Chairman Zafar Mahmood presided over the meeting, which was attended by WAPDA Member (Power) Badrul Munir Murtiza, General Manager (Hydel) Operation Syed Bashir Ahmad and other officers concerned. The meeting was briefed that the hydel electricity delivered to the National Grid during July 2015 registered an increase of 711 million units if compared with 3.723 billion units of hydel electricity generated in July last year, thus, showing 19.1 per cent increase in hydel generation.
This additional contribution of hydel electricity by WAPDA not only helped minimize load shedding in the country during July but also lower power tariff. In addition to the favourable hydrological conditions, effective operation and consistent maintenance of the hydel power stations are the main contributing factors behind this record hydel generation, the meeting noted with utmost satisfaction.
It was told in the meeting that hydroelectric equipment the world over, has a normal life span of 30 to 35 years on the average, but WAPDA still successfully operates its hydel power stations, majority of which are far more old than their average life. Despite aging factor, WAPDA hydel power stations are still capable to be run at their maximum generation capacities.
In high water months, Tarbela and Mangla are capable of delivering electricity more than their installed capacities. During July this year, Tarbela generated upto 3606 MW against its installed capacity of 3478 MW, while Mangla upto 1115 MW against its installed capacity of 1000 MW. It was told in the meeting that the foreign manufacturers of the turbines, who use to visit WAPDA hydel power stations, are surprised by the effective operation and maintenance of the hydel machinery.
In view of the dedication and commitment of WPADA hydel engineers and technicians for achieving optimum generation from the hydel power plants, the Authority today in its meeting acknowledged their services and decided to issue commendation certificates in recognition of their outstanding performance. These hydel engineers and technicians include General Manager, Chief Engineer (Civil) and Chief Engineer (Power) Tarbela; Chief Engineer (Warsak) and the technical staff; General Manager, Chief Engineer, engineers and staff of Mangla Power Station; Chief Engineer (O and M) Besham and all engineers and staff.
It is pertinent to mention that Pakistan inherited two hydel power stations with cumulative generation capacity of only 10.7 megawatt (MW) at the time of independence in 1947 namely Sir Ganga Ram Hydel Power Station of 1.1 MW commissioned in 1925 and Malakand Hydel Power Station of 9.6 MW commissioned in 1937. With WAPDA established in 1958, the hydel generation capacity has so far risen to 6902 MW, which is about one-third of the total system. WPADA contributes about 32 billion units of low-cost hydel electricity on the average to the National Grid every year.
WAPDA operates as many as 19 hydel power stations. The aging factor of WAPDA hydel power stations, which have outlived their average age but still in operation, can be accessed from the fact that Sir Ganga Ram Hydel Power Station at Renal, the oldest of them, is 90 years of age, followed by 63-year old Rasul and Dargai Hydel Power Stations, 57-year old Kurram Garhi, 56-year old Chichoki Mallian, 55-year old unit No. 1 to 4 of Warsak, 54-year old Shadiwal, 52-year old Nandipur, 48-year old unit No. 1 to 4 of Mangla, 41-year old unit No 5 and 6 of Mangla, 40-year old unit No. 1 and 2 of Chitral, 38-year old unit No. 1 to 4 of Tarbela , 34-year old unit No. 7 and 8 of Mangla and unit No. 5 and 6 of Warsak, 33-year old unit No. 5 to 8 of Tarbela and unit No. 3 and 4 of Chitral.
