Sarobi Hydro
Electric Plant
This plant is located at Sarobi on the Kabul River producing
22MW using 2 vertical Francis turbines procured from Germany. The
plant was constructed in 1957. As of Winter 2005, present the
plant is operating at about 70% of the installed capacity due to
lack of maintenance and spare parts. The control panels are not
operational, and are old fashioned and it will be very expensive to
obtain spare parts for them. KfW is financing the complete
rehabilitation of both units with an expected 5% increase in total
capacity. Work should be completed by 2006.Sarobi, clustered in with
Naghlu and Mahipar, has the same seasonal pattern of water flow.
Seasonality of Hydrology at Mahipar
A 5,6 MVA transformer steps down 110 kV to 6 kV for the
Sarobi region. The sub-station switchyard and switchgear are
damaged. The cost for rehabilitation is estimated at USS 700,000.
Rehabilitation
There are gates, tunnel, etc. for installing additional 2 x
14 MW generating units; the power house has to be completely built.
There is always enough water coming from Naghlu dam to run these two
units. Together with Mahipar rehabilitation is as a German grant
($15 million) plus ARTF ($7 million); German grant is handled by KfW
(Lehmayer); starting date was 7/3/2003; expected end of
rehabilitation is 20/3/2007. Right now only one unit can run around
9 MW. There is a need to work very closely with the plant management
to develop economic optimization of water in this power plant.
