BS Link-I Tail Hydropower Project

BS Link 001BS Link-I Tail Hydropower Project would be developed on Balloki-Sulemanki (BS) Link Canal at RD 266+000. BS Link Canal off-takes from the left bank of Balloki Barrage. The proposed project area is located at a Longitude of 73°-55’ East and Latit ude of 30°-28’ North at a distance of 180 km from Lahore. The project area is located in District Okara. The distance of project from Karachi port is about 1215 km by road. The project area can be easily accessed and communicated by all means of communication, i.e., Railway, Road and Telephone systems.

Basic data regarding canal and canal structures in the form of structural drawings and longitudinal section, daily discharge and water level data from 1997-2008 have been collected from the Punjab
Irrigation and Power Department. Topographic mapping and sub-surface drilling were carried out by a private company. The letter of Indent was awarded by Punjab Private Power Development Board to M/s New Park Energy (Pvt) Ltd. The task of preparing the feasibility study was awarded to Fida Hussain Chaudhary – FHC Consulting Engineers, Lahore.

HYDROLOGYBS Link 002
Historic daily discharge and water level data / gauge readings u/s and d/s at RD 266+000 of BS Link Canal have been collected for the period of 1997-2008 from the office of XEN I & P Deptt.

Punjab, Balloki Barrage. A rating curve for the tail water level at RD 266+000 has been established. No sediment sampling has been conducted at any location of the canal by any agency. Therefore, it
is recommended that sediment sampling should be made at this location regularly, so that reasonable historic data is available in order to get sediment concentration and size of the material flowing in the canal at the time of detail design. The canal discharge at proposed powerhouse location has been estimated as 300 m3/s. The same discharge has been used as design discharge for the proposed hydropower scheme. The canal design head water level at RD 266+000 is 179.10m.

POWER AND ENERGY
Power and energy potential of the proposed BS Link-I (RD 266+000) HPP has been investigated in detail taking into consideration the daily discharges passing through the existing fall structure and
corresponding downstream water levels.

The power and energy has been estimated by using the daily historic discharges from 1997 to 2008. The analysis based on daily water level data shows that the head remains in between 3.5 to 4.5 m.
Keeping in view the standardization concept, three (3) number of units based on historic.
