Location: Mangla Dam / Power Station is located on River Jhelum at about 120 Km from Islamabad
Purpose: Mangla Dam is a multipurpose Project, primarily designed for Irrigation. The other by products are Power Generation, Fish Culture, Tourism and Navigation.
Construction: Mangla Power House was completed in four stages. The initial phase comprising of four units of 100 MW each was completed in 1967-69. The first extension of Unit No. 5&6 (2X100 MW) was completed in 1974 while second extension comprising Unit No 7&8 (2X100 MW) was completed in 1981. The project attained its maximum capacity of 1000 MW with the final extension of Unit No 9&10 (2X100 MW) in 1993-94.
Dam Raising: Mangla reservoir had initial gross capacity of 5.88 MAF, which reduced to 4.674 MAF (Year 2005) and was likely to reduce further with the passage of time due to sediment deposition. Keeping in view the capacity loss due to sedimentation and provision for raising in the original design and construction, Raising of Mangla Dam was started in 2004 and the Project was completed in 2009. The Dam height has been raised by 30 feet while maximum conservation level increased from 1202 feet to 1242 feet corresponding to additional water storage capacity of 2.88 MAF. There will be additional energy generation of 644 GWh due to availability of more water and rise in net head of machines.

| Up-Gradation/ Refurbishment Scheme: |
There are four age groups of Mangla machines Units 1~4 (43 years), Units 5~6 (38 years), Units 7~8 (32 years) & Units 9~10 (18 years). The first 6 Units with age of 30~40 years have outlived their useful lives due to which more cost and time are required for maintenance of old equipment besides less operational reliability. Some of the important aspects are:

Submission of Feasibility Study |
Mangla Refurbishment Project JV (MRP JV) submitted Final Feasibility Report in December, 2011 and based on the results of extensive studies, recommended up-gradation from 1000 to 1310 MW at 0.8 Power Factor as it satisfies all the objectives of Scope of Work.
