Central Power Purchasing Agency Guarantee Limited (CPPA) has issued energy procurement report for the month of January 2019 on 13th of February, 2019. This report enlists the energy generated, fuel charges, and variable operation and maintenance costs of operating power plants in Pakistan (except K-Electric System). From this data, total energy charges for each power generating station is computed.
Total electricity generated from all the sources during January 2019 is 7,764 Giga-Watt hour (GWh), slightly up from 7,719 GWh that was produced during December 2018. Analysis of energy procurement report for the month of December 2018 and that of January 2019 reveals that share of electricity generated from hydro power plants significantly decreased from 17% in December 2018 to only 6% in January 2019. Overall generation from hydro power plants only remained 478 GWh in January 2019 and 1,334 GWh in December 2018, which is significantly low because of low-flow season (winter, dry season). Generation from hydro power sources in Pakistan during summer or high-flow season normally range from 35,000 GWh to 45,000 GWh.
Due to low water inflow, as many as fifteen power production units of Tarbela Hydro power plant remain shut during January 2019 that caused an immediate outage of approximately 4,000 MW (Mega-Watt) of electrical power generating capacity from the national grid. Tarbela Dam spokesperson said, “The units stand shut and following the development, water discharge from the dam is likely to curtail further.” The spokesperson added that only two units of the dam were generating some 141MW of power. “The water inflow in the dam is 14,600 cusecs while the outflow is 5,000 cusecs. The water level in the dam is 1,423.65 feet while the dead level is 1,388 feet.”
Bad weather and smog also played their parts and caused shutdown of Balloki, Guddu, Nishat and Nishat Chuniyan power plants during January 2019.
Another thing worth mentioning is that 1,722 GWh (22%) electricity is generated from expensive furnace oil during January 2019. Share of oil generated electricity during December 2018 was 12% (931 GWh). Electricity generated from Coal fired plants slightly decreases from 1,563 GWh (20%) in December 2018 to 1,451 GWh (19%) in January 2019. This increase in electricity generated from expensive oil, and low generation from cheap hydro power plants increases the per unit energy cost, which is around Rs. 7.31/kWh for January 2019 as compared with Rs. 5.80/kWh in December 2018.
