PATAN HYDROPOWER PROJECT
1.0 General
The Pakistan Water and Power Development Authority (WAPDA) launched a 25
years comprehensive integrated programme in 2001 Water Resources and
Hydropower Development Vision 2025. Programme which aims at the
development of water storage projects as well as harnessing the hydropower
potential in the country. Thakot Hydropower Project, being a run off river
hydropower project, is also included in that programme.
2.0 Location
Patan Hydropower Project is located on Indus River in District Kohistan of NWFP.
The dam site is located on Indus River about 4 Km upstream of village Patan onKarakorum Highway (KKH). The proposed underground powerhouse site is
located on the left bank about 8 km upstream of Besham Town and is accessible
via KKH. Powerhouse and dam sites are 349 km and 383 km respectively from
Islamabad.
3.0 Background
WAPDA in 1975 requested the assistance of Canadian Government through
CIDA in making ranking study of hydroelectric power sites with a view to meet the
long-term power demand of Pakistan. Accordingly CIDA provided a grant to
assist WAPDA in cost effective hydropower sites and to focus on the best-ranked
project for development / implementation.
CIDA appointed Montreal Engineering Company Limited (MONENCO) to
undertake hydroelectric inventory ranking and feasibility studies in Pakistan. The
contract between CIDA and Consultant (MECO) was signed on August 5, 1981.
Patan Hydropower Project was identified as part of Inventory and Ranking Study
of Hydropower potential on main rivers of Pakistan, carried out in
1981-84. For main-stem Indus River Projects, Patan Project was ranked fifth after
Basha, Dasu, Bunji and Thakot hydropower projects.
Monenco studies revealed at identification level that Patan Hydropower Project
would utilize the steep river gradient available on Indus river. The concept of
development was to construct a 104 m high dam on Indus river. The project

would provide some 1172 MW (Index Capacity) in an underground powerhouse
with gross head of 150 m and design discharge of 1070 m3/s.
The Index capacity at Identification study by Monenco was reviewed and revised
as 2800 MW with design discharge of 2600 m3/s and mean annual energy of
15,230 GWh by Hydro Planning Organization with updated flow data and design
discharge.

- Gross Head : 150 m
- Net Head : 129 m
- Mean Annual Energy : 15230 GWh
- Mean Annual Flow : 2180 m3/s.
- Dam height : 104 m
- Length of Power Tunnel : 18 Km
- Tentative Project Cost ; 6.0 Billion US $
Scope fpr Feasibility Study
The study will cover data collection, field investigations, technical analysis to select
the appropriate project lay out to develop the hydro power potential required to fully
establish the feasibility of the selected project layout, design of structure and
equipments, cost estimates, economic and financial analysis for the Patan
Hydropower project.
The works for a feasibility study are indicated below :
Field surveys and investigations
Collecting of all relevant data
Finalization of project layout after considering different alternatives.
Design of Structures and equipments,
