Pakistan - Land of great contrasts

Pakistan has a semi-industrialized economy based largely on agriculture and a growing service sector. With one of the world's largest and fastest-growing middle classes, Pakistan is ranked among the emerging and growth-leading economies.

Over the last several years, the macroeconomy has stabilized. However, to attract foreign investment and support further economic growth, additional economic reform and development of the energy sector is necessary.

Pakistan’s energy mix is split among fossil fuels (69%), hydropower (21%) and other renewables and nuclear power (10%). In April 2019, Pakistan declared to have 30% of its energy capacity coming from renewable sources by 2030. The International Hydropower Association states that Pakistan has a technically feasible hydropower potential of about 60,000 MW.

Pakistan ranked as the world’s No. 3 in ­hydropower installation.

During 2018, three long-delayed mega hydropower projects were successfully completed and commissioned. With a cumulative generation capacity of 2,487 MW, the projects include the commissioning of the 108 MW Golen Gol hydropower project, the 1,410 MW Tarbela fourth extension, and the 969 MW Neelum Jhelum hydropower projects.

In 2018, close to 22 GW of new renewable hydroelectric capacity was put into operation worldwide. By commissioning additional capacity collectively reaching 2,487 MW, Pakistan is positioned as the world's number 3 in hydropower installation ranking. Following only China (8,540 MW) and Brazil (3,866 MW), Pakistan's hydropower is making a significant contribution to a clean and sustainable future.

ANDRITZ Hydro in Pakistan

ANDRITZ has been active in Pakistan for more than 75 years, supplying equipment and complex project execution. Across Pakistan to date, more than 71 units with a total capacity of 4,723 MW have been installed and/or rehabilitated by ANDRITZ. Among the long list of important projects for ANDRITZ are Allai Khwar with 121 MW and Duber Khwar with 130 MW. Both of these projects, which have been completed and handed over to the customer, are outstanding signature projects representing the first high head Pelton units in Pakistan.

New Bong Escape (84 MW): This project, the first private large hydropower station in Pakistan, features four Kaplan Bulb turbines each rated at 21 MW.

Suki Kinari (840 MW): ANDRITZ was awarded a contract to supply four 210 MW Pelton units for this project, which will be the largest Pelton turbines in the country.

Tarbela Dam (6,298 MW): Tarbela Dam is an earth-filled dam along the Indus River and the largest of its kind in the world. It is also the largest dam by structural volume. Completed in 1976 and designed for irrigation as well as flood control, the generation of hydroelectric power is the dam’s primary function. ANDRITZ was the OEM for all units except the earliest units, #1 - #4. The company has also been awarded  several projects at Tarbela, including modernizing, refurbishing and delivering electro-mechanical equipment, the world’s largest penstocks as listed in the Guiness Book of World Records, and gates. The existing powerhouse consists of 14 units (10 × 175 MW, 4 × 432 MW). The installed capacity of 4,888 MW will be increased to 6,298 MW after completion of the planned fifth extension.
