Brief Description:
Karora Hydropower Project has been
conceived as a run-of-river scheme on Khan Khwar which is right tributary of
Indus River in Shangla district of Khyber Pakhtunkhwa. The Project is nearly 25
km from Besham accessible through Besham-Mingora road while 225 km from
Islamabad.
The feasibility study of Karora
Hydropower Project was completed in August 2011 later on the construction of
the project started in December 2014. The under construction weir site is
located on Khan Khwar near village Kuz Kana while power house is proposed near
Marine village 5.2 Km downstream of the weir site. The proposed scheme
comprises diversion weir with lateral intake, conveyance box channel, leading
the water to sand trap from where sand free water enters into headrace tunnel.
The under construction headrace tunnel is designed as a horse shoe shape of
diameter 2.6m concrete lined. The tunnel is 2954m long and has a slope of 1 in
250.
At the end of tunnel a surge shaft
of 8m diameter is provided which is connected to 1.8m diameter and 408m long
penstock. At the end of penstock the inlet valves of each (of the two)
Horizontal Francis turbine with installed capacity of 6.24MW (Q=4.875 m3/sec,
Head=142m) each turbine is connected to a generator of 6.94MVA capacity. The
annual energy= 71.39Gwh and plant factor= 69.06%. The power will be evacuated
through 132KV-10 Km transmission line and interconnected at Besham Qilla.
The project is sponsored by the
government of Khyber Pakhtunkhwa through 10% provincial ADP and 90% through
Hydel Development Fund/Foreign Investment. The project will add the 11.80MW
electric power in national grid.
