Verification of Project Works Completed up to 21 July, 2012

The visit was conducted by AEAI engineers to expedite the completion of rehabilitation works under USAID funding, inspect recently installed equipment, and verify WAPDA reimbursement claims under FARA. As of July 21, 2012, Tarbela Power Station's total generation was 2800 MW at a reservoir level of 1455 ft. The installation of new Class F winding at Unit # 3 resulted in an additional 10 MW capacity gain, bringing the total added capacity under the FARA rehabilitation program to 128 MW. The unit was operating at 150 MW at a reservoir level of 1455 feet, with all technical parameters and winding temperatures within technical limits. The progress of the rehabilitation works is summarized as follows: Unit # 4 winding was replaced with new Class F winding in May 2011, adding 108 MW capacity; Unit # 1 winding was replaced with new Class F winding in February 2012, adding 10 MW capacity; and Unit # 3 installation, testing, and commissioning were completed on May 25, 2012, under the supervision of the manufacturer's representative. The unit was operating at 150 MW at a reservoir level of 1455 feet, with all technical parameters and winding temperatures within technical limits. WAPDA/Tarbela reimbursement requests for successful installation of Unit 3 winding and replacement of seals for Relief and Bypass Valves Units 1-10 were verified and certified by AEAI. WAPDA/Tarbela received US $370,000 and US $50,000, respectively, in their account on July 20, 2012, and May 21, 2012. New Station Drainage Pumps and Unwatering Pumps arrived at Tarbela and were installed in the Drainage and Unwatering Sump, with the existing pump performing satisfactorily since its commissioning. The manufacturing of Digital Governors was completed at GE, USA, and four WAPDA engineers inspected the Governors at GE Works in July 2012. The installation of new Governors is scheduled to commence during the low flow season in November-December 2012 and is expected to be completed by June 2013 on all ten units. WAPDA was requested to submit a time extension request with detailed justifications for delays. The new SCADA system is under manufacturing with ABB and shipment is scheduled in October 2012, with installation requiring another three months. WAPDA was requested to submit a time extension request with detailed justifications for delays.
