Mangla Dam Hydel energy since its commissioning. The annual generation during 2008-2009 was 4797.425 Million KWh while the station shared a peak load of 1150 MW which was 8.18% of the total WAPDA system peak. On 1 September 2013, the water level in Mangla Dam reached to a record height of 1237.15 feet against the maximum conservation level of 1242 feet. "Radio Pakistan" reported that "the water level in Mangla Dam has attained maximum height of 1237.15 feet in the history and it is still increasing." Mangla reservoir had an initial reservoir capacity of 5.88 Million Acre-feet (MAF), which reduced to 4.674
Mangla Dam 7-8 were manufactured by ACEC, Belgium and were installed in 1981, while the remaining two turbines are a make of Škoda, Czech Republic and were commissioned in 1994. These turbines are connected to umbrella-type generators which have a generation capacity of 100 MW. Hitachi, Japan had provided generators for turbines 1–4 and 7-8 while Škoda generators are connected to turbines 5-6 and 9-10. These generators are in turn connected to three-phase transformers. The transformers connected to turbine 1, 4 and 7 were manufactured by the Italy-based Savigliano. The transformers for turbine 5 and 6 are a make of , another
