1. Project information

Background:

Project Rationale and History

1. The Central Asia-South Asia Electricity Transmission and Trade Project (CASA-1000) aims to facilitate electricity trade between hydropower surplus countries in Central Asia and electricity deficient countries in South Asia by putting in place the commercial and institutional arrangements and the transmission infrastructure required for this trade. The four countries participating in the project – Afghanistan, Kyrgyz Republic, Pakistan and Tajikistan – are of considerable geostrategic importance by virtue of their location at the crossroads of China, India, Russia and the Middle East. Sustained efforts to promote institutional development and socio-economic prosperity in the CASA-1000 countries are therefore a very high priority, not only for the countries themselves, but also for the stability of the Central and South Asia regions. The CASA-1000 countries vary significantly in terms of population numbers, economic size and development trajectories, but also share several key characteristics and have complementary development needs and goals, especially in the energy sector, which form the basis for the CASA-1000 project.

2. The project envisages a transmission interconnection between the Central Asia and South

Asia Regions that would be used to export surplus electricity in the summer from existing generation capacity in Kyrgyz Republic and Tajikistan to energy-deficient Afghanistan and Pakistan. The feasibility confirmed the soundness of the considerations that: (i) sufficient quantities of surplus electricity are available in the Central Asian countries (the Kyrgyz Republic and Tajikistan), even under conservative estimates of no new generation project; (ii) a significant need for electricity imports exists in South Asia (particularly Pakistan) to meet existing and projected demand; and (iii) the differences in the cost of electricity between the importing and exporting countries potentially provide a justifiable rationale to make transmission investments to support the electricity trade.

Project Description

3. The project will build a cross-border power trade facility, comprising about 475 km of 500kV HVAC transmission lines to carry power from Kyrgyz Republic to Tajikistan at Khodjant; a 1300 MW HVDC converter in Tajikistan (at Sangtuda) and thereafter a 750km long ±500kV HVDC transmission link via a 300 MW HVDC converter in Kabul, to a 1,300 MW terminal with HVDC converter facilities in Pakistan. The AC to DC convertor station would be designed to help power trade in any direction and would offer significant emergency system support to the national grids of the countries connected through HVDC system.

4. The CASA-1000 feasibility study proposes a route for the line that takes into consideration cost effectiveness, security (especially in Afghanistan and Pakistan to avoid areas that would require significant demining), terrain to facilitate easier operations and maintenance and minimizing social and environmental impacts. For the most part the line traverses a manageable topography with the exception of a narrow and high mountain range in Afghanistan known as the Salang Pass which offers the most direct route linking the North East Power System (NEPS) with Kabul. In the possible scenario of space constraint in that area, alternative options to bypass the Salang pass will be adopted. The final route of transmission line will be designed by the transmission line contractor within the first year of the contractor’s scope of work. Figure 1 gives the project schematic and shows the route of the HVAC and HVDC transmission lines.

Project Implementation and Commercial Framework

5. The four project countries will be implementing CASA-1000 as a public sector project through their respective NTCs (national transmission companies) with support from IFIs (international financial institutions) and other donors. All the Project assets will be owned by the respective NTCs within the boundaries of their own country which are the following:

a. In Afghanistan - Da Afghanistan Breshna Sherkat (DABS)

b. In the Kyrgyz Republic - Joint Stock Company (JSC) National Electric Grid of

Kyrgyzstan (NEGK)

c. In Pakistan - National Transmission and Despatch Company (NTDC)

d. In Tajikistan - Open Joint Stock Holding Company Barki Tojik (BT)

Procurement Arrangements

6. The project procurement is complex and the nature of major procurement packages requires close coordination among the four implementing countries not only to ensure smooth procurement, but also to synchronize project implementation activities keeping in mind overall project sequencing. Market conditions and security concerns along the route of the proposed transmission line add to the complexity of the procurement plan and structure. Hence the project’s implementation arrangements include an intergovernmental mechanism for the procurement and contract management decision-making process for the joint procurement packages for the countries. The IGC has established through a resolution a Procurement Sub-Committee (PSC), comprising senior technical and procurement staff designated by each country. The PSC will carry out all the work needed on behalf of the parties to oversee and bring to successful closure the entire procurement process leading to award of the contracts by the NTCs. The NTCs will follow their respective corporate procedures for internal clearances of procurement and contract awards and assist the PSC in its work. This arrangement has helped in streamlining the joint procurement process and is expected to lead to timely award of all the major DS&I (design, supply and installation) contracts on the project.

7. The major procurements under the project include the HVDC stations in three countries, HVDC and HVAC transmission lines and O&M contracts. Though all the implementing agencies have some experience in managing such large and complex contracts, they do not have sufficient resources to help with drafting of the Pre-Qualification / bidding documents and the evaluation reports, hence, these functions are being facilitated by an international engineering consultancy company (Power Grid Company of India, or PGCI) that has already been appointed by IFC. Progress in the procurement process has already been made, with the launch of the prequalification process for selection of the EPC contractors for the HVDC Convertor stations. As a result of the PQ announcement, the qualification documents submitted by interested firms are currently under review by PGCI. Following a similar approach, the selection process on the transmission line components will be undertaken by the PSC in due course of time with the assistance of

PGCI.

Project Components

10. The Project has been divided into three broad components: Component A - High Voltage Transmission Infrastructure, Component B – Project Management and Capacity Building, and Component C- Community Support Program. For the purposes of this assignment, which pertains to the responsibilities of Owner’s Engineer, the details of the High Voltage Transmission Infrastructure (Component A) are given hereunder:

(i) Sub-component A1 – High Voltage Direct Current (HVDC) Transmission Line which involves the construction of approximately 750 km of 500 kV HVDC overhead transmission line to interconnect the electricity network of Tajikistan, at the Sangtuda substation (s/s), with the Pakistan network, at the Peshawar substation, via the Kabul substation in Afghanistan. The line will have a transmission capacity of 1,300 MW in either direction, using a bipolar and earth-return configuration and will consist mainly of self-supported lattice tower structures, conductors, and insulators. About 120 km of the line will be in Tajikistan, 560 km in Afghanistan, and 70 km in Pakistan. (Note: This section is not included in the scope of the AC Owner Engineer).

(ii) Sub-Component A2 – HVDC Converter Stations which involve the engineering design, construction, and commissioning of three High Voltage Alternating Current (HVAC) to Direct Current (DC) converter stations at Sangtuda s/s (1,300 MW) in Tajikistan, Kabul s/s (300 MW) in Afghanistan, and Peshawar s/s (1,300 MW) in Pakistan. These convert AC power into DC, and vice versa, as needed. The s/s main equipment package includes specialized converter transformers, breakers, filtering equipment, inverters, controls, ground electrodes, and static and dynamic compensation equipment. (Note: This section is not included in the scope of the AC Owner Engineer).

(iii) Sub-component A3 – Kyrgyz-Tajik HVAC Transmission Interconnection which includes the construction of about 475 km of 500 kV HVAC overhead transmission line to interconnect the electricity network of the Kyrgyz Republic, at Datka s/s, with the Tajikistan network, at the Khudjand s/s. About 450 km of the line will be in the Kyrgyz Republic and 25 km in Tajikistan.

(iv) Sub-component A4 – Tajikistan grid reinforcement which includes reinforcements in Tajikistan including construction of 500 kV line from Regar s/s to Sangtuda s/s and other parts of the network necessary to ensure transfer of Tajikistan and Kyrgyz export power to Sangtuda HVDC station.

11. Two consultancy firms (one for the HVDC network and another for the HVAC system) will be selected through a competitive process to act as Owner’s Engineers. These consultants will be responsible for assisting the CASA-1000 countries in supervising the EPC contracts until handing over and commercial operation of the facilities, certifying contractors’ payments, and assisting the IGC Secretariat with coordination among all relevant institutions. There will be a single EPC contract for the DC stations while it’s anticipated that the DC and AC transmission lines will be divided among a number of EPC contractors depending on the procurement rules of the financiers who will be funding these facilities. In this regard, as a first step, the NTCs, with the assistance of PGCI, are finalizing the selection of the EPC contractor for the various components of the project. Figure 2 shows the institutional arrangements for the implementation of the project and indicates the lines of responsibility of the Owner’s Engineers.

The above is the detailed background and scope of the overall project and from this point onward details relating to the AC Network and the roles and responsibilities of the Owner’s Engineer (The Consultant) for the AC Network are being provided.

I. Project information

Background:

Project Rationale and History

1. The Central Asia-South Asia Electricity Transmission and Trade Project (CASA-1000) aims to facilitate electricity trade between hydropower surplus countries in Central Asia and electricity deficient countries in South Asia by putting in place the commercial and institutional arrangements and the transmission infrastructure required for this trade. Sustained efforts to promote institutional development and socio-economic prosperity in the CASA-1000 countries are a high priority for the World Bank Group. The CASA-1000 countries vary significantly in terms of population numbers, economic size and development trajectories but they have complementary development needs and goals, especially in the energy sector.

2. The project envisages a transmission interconnection between the Central Asia and

South Asia Regions that would be used to export surplus electricity in the summer from existing generation capacity in Kyrgyz Republic and Tajikistan to energy-deficient Afghanistan and Pakistan. The feasibility study confirmed the soundness of the considerations that: (i) sufficient quantities of surplus electricity are available in the Central Asian countries (the Kyrgyz Republic and Tajikistan), even under conservative estimates of no new generation project; (ii) a significant need for electricity imports exists in South Asia (particularly Pakistan) to meet existing and projected demand; and (iii) the differences in the cost of electricity between the importing and exporting countries potentially provide a justifiable rationale to make transmission investments to support the electricity trade.

Project Description

3. The project will build a cross-border power trade facility, comprising about 475 km of 500kV HVAC transmission lines to carry power from Kyrgyz Republic to Tajikistan at Khoudjand; a 1300 MW HVDC converter in Tajikistan (at Sangtuda) and thereafter a 800km long ±500kV HVDC transmission link to a 1,300 MW terminal with HVDC converter facilities in Pakistan. The AC to DC convertor station would be designed to help power trade in any direction and would offer significant emergency system support to the national grids of the countries connected through HVDC system. The 300 MW Converter station at Kabul has been shelved and instead ,Tajikistan would supply 300 MW of power to Afghanistan through the existing 220 kV AC transmission line from Sangtuda to Pul-e-Khumri. A 500 MW BTB Converter station (not in the present OE scope) at Pul-e-Khumri will receive power from Tajikistan and transmit it further to Kabul and other provinces of Afghanistan.

4. The CASA-1000 feasibility study proposes a route for the line that takes into consideration cost effectiveness, security (especially in Afghanistan and Pakistan to avoid areas that would require significant demining), terrain to facilitate easier operations and maintenance and minimizing social and environmental impacts. For the most part the line traverses a manageable topography with the exception of a narrow and high mountain range in Afghanistan known as the Salang Pass. In the possible scenario of space constraint in that area, alternative options to bypass the Salang pass will be adopted. However, due to restructuring of HVDC terminal stations & based on preliminary survey, new route via Kunduz-Pul-e-Khumri-Kabul has been agreed upon. The final route of transmission line will be designed by the transmission line contractor within the first year of the contractor’s scope of work.

Figure 1 gives the project schematic and shows the route of the HVAC and HVDC transmission lines.

Project Implementation and Commercial Framework

5. The four project countries will be implementing CASA-1000 as a public sector project through their respective NTCs (national transmission companies) with support from IFIs (international financial institutions) and other donors. All the Project assets will be owned by the respective NTCs within the boundaries of their own country which are the following:

a. In Afghanistan - Da Afghanistan Breshna Sherkat (DABS)

b. In the Kyrgyz Republic - Joint Stock Company (JSC) National Electric Grid of

Kyrgyzstan (NEGK)

c. In Pakistan - National Transmission and Despatch Company (NTDC)

d. In Tajikistan - Open Joint Stock Holding Company Barki Tojik (BT)

6. One of the key characteristics of project design is the provision of open access by third-parties to the CASA-1000 transmission system for power trading during the non-supply period (or the period when the countries have committed to fully utilize the HVDC line). The CASA-1000 countries all agree to this principle and as such are defining and developing appropriate ‘open access’ rules and procedures to manage and facilitate these future transactions. This includes defining the participants in the transaction(s), access charges, main characteristics of the allocation mechanism of capacity to third parties, contracting arrangements, operational planning and congestions management including responsibility for dispatch and management of the transactions. Given the limited experience in the region on third party access, it is important to develop this in a phased manner.

Procurement Arrangements

7. The project procurement is complex and the nature of major procurement packages requires close coordination among the four implementing countries not only to ensure smooth procurement, but also to synchronize project implementation activities keeping in mind overall project sequencing. Market conditions and security concerns along the route of the proposed transmission line add to the complexity of the procurement plan and structure. Hence the project’s implementation arrangements include an intergovernmental mechanism for the procurement and contract management decision-making process for the joint procurement packages for the countries. The IGC has established through a resolution a Procurement Sub- Committee (PSC), comprising senior technical and procurement staff designated by each country. The PSC will carry out all the work needed on behalf of the parties to oversee and bring to successful closure the entire procurement process leading to award of the contracts by the NTCs. The NTCs will follow their respective corporate procedures for internal clearances of procurement and contract awards and assist the PSC in its work. This arrangement has helped in streamlining the joint procurement process and is expected to lead to timely award of all the major DS&I (design, supply and installation) contracts on the project.

8. The major procurements under the project include the HVDC stations in two countries, HVDC and HVAC transmission lines and O&M contracts. Though all the implementing agencies have some experience in managing such large and complex contracts, they do not have sufficient resources to help with drafting of the Pre- Qualification / bidding documents and the evaluation reports, hence, these functions are being facilitated by an international engineering consultancy company.

Procurement of all contracts , except for the O&M contract has been under way.

Progress of Procurements as below

• HVDC Converter Stations at Pakistan and Tajikistan – First stage /Technical bid expected to be opened in May’17.

• HVDC Transmission Line In Afghanistan – Under Finalization of Contract award

• HVDC (including AC part) Transmission Line in Pakistan – Bidding process for invitation of bids from pre-qualified bidders launched.

• HVDC Transmission Line and AC Transmission Line (Part) in Tajikistan –

Bidding process for invitation of bids from pre-qualified bidders launched.

• AC Transmission Line (Part) in Kyrgyzstan – Bidding process for invitation of bids from pre-qualified bidders launched.

• AC Transmission Line (Part) and Sub-station Extension in Tajikistan and Kyrgyzstan – Bidding process for invitation of bids being launched.

Project Components

9. The Project has been divided into three broad components: Component A - High Voltage Transmission Infrastructure, Component B – Project Management and Capacity Building, and Component C- Community Support Program. For the purposes of this assignment, which pertains to the responsibilities of Owner’s Engineer, the details of the High Voltage Transmission Infrastructure (Component A) are given hereunder:

(i) Sub-component A1 – High Voltage Direct Current (HVDC) Transmission Line which involves the construction of approximately 800 km of 500 kV HVDC overhead transmission line to interconnect the electricity network of Tajikistan, at the Sangtuda substation (s/s), with the Pakistan network, at the Nowshera substation.

The line will have a transmission capacity of 1,300 MW in either direction, using a bipolar and earth-return configuration and will consist mainly of self-supported lattice tower structures, conductors, and insulators.

(ii) Sub-Component A2 – HVDC Converter Stations which involve the engineering design, construction, and commissioning of two High Voltage Alternating Current (HVAC) to Direct Current (DC) converter stations at Sangtuda s/s (1,300 MW) in Tajikistan and Nowshera s/s (1,300 MW) in Pakistan. These convert AC power into DC, and vice versa, as needed. The s/s main equipment package includes specialized converter transformers, breakers, filtering equipment, inverters, controls, ground electrodes, and static and dynamic compensation equipment.

(iii) Sub-component A3 – Kyrgyz-Tajik HVAC Transmission Interconnection which includes the construction of about 475 km of 500 kV HVAC overhead transmission line to interconnect the electricity network of the Kyrgyz Republic, at Datka s/s, with the Tajikistan network, at the Khudjand s/s. About 450 km of the line will be in the Kyrgyz Republic and 25 km in Tajikistan. (Note: This section is not included in the scope of the DC Owner Engineer).

(iv) Sub-component A4– Tajikistan grid reinforcement which includes reinforcements in

Tajikistan including construction of 500 kV line from Regar s/s to Sangtuda s/s and other parts of the network necessary to ensure transfer of Tajikistan and Kyrgyz export power to Sangtuda HVDC station. (Note: This section is not included in the scope of the DC Owner Engineer).

10. Two consultancy firms (one for the HVDC network and another for the HVAC system) will be selected through a competitive process to act as Owner’s Engineers. These consultants will be responsible for assisting the CASA-1000 countries in supervising the EPC contracts until handing over and commercial operation of the facilities, certifying contractors’ payments, and assisting the IGC Secretariat with coordination among all relevant institutions.
