VISIT OBJECTIVESFollowing were the key objectives of site visit carried out by Transmission Expert of AAAssociates:

1. To monitor the progress of construction activities

2. To observe the challenges in implementation of the activities and to carry outdiscussion/coordination with NTDC to resolve them

VISIT PROCEEDINGSThe team reached Patrind Power House at 11:30 AM on May 11, 2017. 132kV Transmission Linefrom Patrind Hydropower Project to Muzaffarabad-II (Rampur) Substation constructed underNTDC own sources as Phase-I of Transmission Scheme for Evacuation of power from 147MWPatrind Hydro Power Project is complete and energized recently.

132KV TRANSMISSION LINE FROM PATRIND HPP TO 220KV MANSEHRASUBSTATIONThe work on foundations and erection of towers for 132kV Double Circuit Transmission Line fromPatrind HPP to 220kV Mansehra Substation is in progress. The progress achieved so far is:

o Foundation (Conventional) Concreted 126/163o Pile Foundation 12/23o Tower Erected 38/183

Scheduled completion date was April 30, 2017, but the project seems delayed due to followingreasons:

o Sub Divisional Engineer (EHV-I) told that NTDC had to face demand of heavycompensation by some affectees against right of way, eventually resulting in delay inproject execution.

o Batrasi is a “Reserved Forest” in Khyber Pakhtun Khuwa (KP) Province. The Contractor’ssurveyor told that passing of transmission line through Batrasi Forest cannot be avoidedbecause of thick population on alternate route. About eleven (11) towers are proposed tobe located in Batrasi Forest. Delay in settlement/negotiation with KP Forest Departmenthas hindered the project progress.

AA Associates requested Sub Divisional Engineer (EHV-I) NTDC to further search alternate routeto avoid Batrasi Forest, as obtaining permission/No Objection Certificate from Forest Departmentseems to be difficult. Furthermore, because of reserved status of the forest it would be worthwhileto avoid the passage of transmission line through forest. AA Associates will follow-up the matterwith PD office for early resolution of these issues.

132KV BALAKOT SUBSTATION132kV Balakot Substation was visited and it was found to be in a devastated shape as noreconstruction/repair of boundary wall, control building and residential colony was carried out aftersevere earthquake of 2005. The substation was however, operational with battery, control & relaypanels and 11kV metal clad switchgear in a temporary shed without walls. It was observed thatrequired space for extension of switchyard and for location of further terminal tower was notavailable because of surrounding residences.

A new 132kV substation is proposed by NTDC/PESCO at Garhi Habibullah where two 132kV linebays for In/Out of one circuit of 132kV Transmission Line from Patrind HPP to Mansehra can beadded under USAID financing.

PESCO officials at Balakot Substation were not aware of the status of acquisition of land at GarhiHabibullah. Therefore, Executive Engineer (Substation & Transmission Line) Grid SystemOperation PESCO Abbottabad, who is responsible for maintenance of substations andtransmission lines in the area, was contacted on telephone. Even he was not aware of the finalstatus of acquisition of land and timeline for construction of the substation.

220/132 KV MANSEHRA SUBSTATIONThe team reached Mansehra Substation where subcontractor’s engineer was available whoexplained the progress of construction work. It was noted that 220/132kV, 250MVA Transformershave been placed on foundations, grey structure of control building was complete and, erection of220kV & 132kV equipment in switchyard was in progress.

There are six 132kV line bays in the scope of work, which were for interconnection of 132kVTransmission Lines to PESCO’s distribution network. Due to delay in initiating the activitiespertaining to additional two 132kV line bays by NTDC under USAID financing, and urgentrequirement of interconnection of 132kV Double Circuit Transmission Line from Patrind HPP forevacuation of power, two of the line bays being constructed under ADB financing aremarked/reserved for termination of 132kV Double Circuit Transmission Line from Patrind HPP.

However space is available for additional two 132kV line bays, (to be constructed under USAIDfinancing) for which, no activity has yet been initiated by NTDC in spite of repeated requests fromAA Associates to GM (GSC) & CE (Design).

WAY FORWARD AA Associate will contact P.D (EHV-I) NTDCL Islamabad & XEN (EHV-I) Rawalpindi for

timely diversion of the route of 132kV Patrind-Mansehra Transmission Line to avoid itscrossing of Batrasi reserved forest.

MIMDR | SITE VISIT REPORT | MAY 2017 | 4

AA Associates will contact CE (Development) PESCO to know updates on acquisition ofland and timeline for construction of new 132kV substation at Garhi Habibullah, so that two132kV line bays for In/Out of 132kV Patrind HPP-Mansehra Transmission Line can beinitiated by NTDC accordingly.

AA Associates will pursue the matter with NTDC to initiate the activities for addition of two,132kV line bays at 220kV Mansehra Substation.

Site Visit Report Activity/Award Title : Power Transmission System for Patrind Hydropower Activity AOR/COR/Program manager : Imran Ahmed PIL Signing Date : Sept 1, 2018 Activity End Date : Sept 30, 2020 Visit Date : From: Sept 26, 2018 To: Sept 27, 2018 Visit Site : 132kV Patrind-Mansehra Double Circuit Transmission Line and 220 kV Mansehra Substation Visit Conducted By : Muhammad Ashraf Khan, Sajid Ali Visit Purpose : Activity Monitoring

Site Visit Objective(s):

● Monitoring of progress ● To assess bottlenecks/cause of delay in completion of project.

Status of Progress and Way Forward: Status of Progress of Transmission Line:

- Foundation 160/167 - Pile Foundation 25/25 - Total Foundation constructed 185/192 - Tower Erection 176/192 - Stringing 32km

Status of Line Bays at Mansehra Substation: • Two 132 kV Line Bays already constructed at 220/132 kV Mansehra Substation are reserved for

interconnection of 132 kV Patrind-Mansehra circuits. Installation of line P.T and synchronizing panels is required.

• Procurement of equipment for new line bays is in progress, preliminary construction drawings issued by C.E (Design) NTDC.

Reasons of Delay: The expected completion date of the activities as per PIL is August 2018. The delay is due to following factors: • The terrain involves crossing of river and requires construction of more pile foundations (than

conventional ones) than originally planned. • Unpredictable weather necessitating manual excavation for tower foundation. • Diversion necessary to avoid reserved forest Batrasi. • Right of Way problems on tower no. 110,111,112 in Khyber Pakhtunkhwa area have been solved and

towers will be concreted within next the ten days. • Right of way problems at tower location. 17P,6,7,8 and 11 are complicated: land owners demand

exorbitantly high compensation. NTDC approached Azad Jammu Kashmir (AJK) administration but no resolution so far.

Way Forward: • MIMDR requested site engineers to share next target date completion date of these activities. NTDC

engineer responded that right of way problem of towers concreting in AJK area is complicated. NTDC higher authorities to take up the matter with AJK Government and establish revised completion date(s) accordingly.

Site Visit Objective(s):● Monitoring of progress.● To assess bottlenecks/cause of delay in completion of Project.

Status of Progress and Way Forward:Status of Progress of Transmission Line:

- Foundation 165/169- Pile Foundation 25/25- Tower Erection 179/194- Conductor Stringing 37.339km/40.695km- Optical fiber Ground Wire (OPGW )Stringing 37.589km/40.695km

Status of Line Bays at Mansehra Substation: Two 132 kV Line Bays have been constructed, except voltage Transformer, and reserved for

interconnection of 132 kV Patrind-Mansehra circuits. The foundations for two voltage transformersare ready for installation. The process is expected to take a maximum of one weeks after reachingvoltage transformer on site.

Procurement of equipment for new line bays is in progress: C.E (Design) NTDC has issued preliminaryconstruction drawings.

Reasons of Delay:Expected completion date of activities as per PIL was August 2018. The following factors havecontributed to the delay so far: Involvement of more pile foundations in place of conventional ones and crossing of river. The route initially proposed intersected the Batrasi forest reserve, necessitating the need for a

diversion. Tower concreting on tower no. 17P in Azad Kashmir will be carried out within the next ten days, as

Right of Way (ROW) problems have been resolved. Landowners at tower locations 6, 6A, 7 and 8 demanded exorbitantly high compensation for granting

ROW. NTDC approached Azad Jammu Kashmir (AJK) administration for an amicable resolution butmet with no success.

Way Forward: MIMDR met with NTDC site engineer to discuss estimated date(s) of completion for delayed

activities. NTDC maintains that the ongoing ROW issue is complicated and has caused a slow work.Once the issue is resolved, the work is expected to (approximately) a month to complete. NTDChigher authorities plan on following up with the AJK Government to move the issue forward.
