5 FBC POWER STATION LAKHRA
Ever since commissioning , this Plant faces many technical problems resultantly its availability and performance remained low, during 2001, it was decided that the Government of Sindh should take necessary action to privatize Lakhra Power Plant in consultation with Wapda. The privatization process of this plant remained very slow.

6 The station management in 2003 made a rehabilitation programme amounting to Rs.441 million which was scrutinized by a Tech Committee in June ’03 on the directive of BOD meeting. However based upon Non Destructive Testing by experts of WAPDA Central workshop Faisalabad and historical data of Shutdowns, areas of replacements further reduced and expenditure to Rs.254 million.

7 But later it was decided to lease out Lakhra Power Plant and related facility on ROMM (Rehabilitation Operation Maintenance, & Management basis). In result of an open bid , agreement for 20 years was signed on between LPGCL and M/s Associated Lakhra Energy Limited. The management has stopped the comprehensive maintenance of Lakhra Power Plant after the lease agreement.

8 The Zonal Labor Union Lakhra has filed a petition in Sindh High Court , Challenging the leasing of Lakhra Power Plant . M/s Habibullah energy the other bidder also filed petition in Sindh High Court against leasing . After the Court case , the local management strives hard and rehabilitates the boiler No.1 and finally commission the boiler on Since then same unit is under operation successfully on 35 MW continuously.

9 On both Petitions Sindh High Court Hyderabad Circuit decides in favour of leasing.
Labour Union & M/s Habibullah Energy appealed in the Supreme Court of Pakistan against the decision of High Court of Sindh., which is still pending. The date is in office from April 2010
