1 NEPAL ELECTRICITY AUTHORITY (An Undertaking of Government of Nepal) Project Management Directorate Terms of Reference (ToR) For Consulting Services For Feasibility Study of Second Nepal-India 400 kv Cross Border Transmission Line Project (Bardaghat-Gorakhpur 400 kv Transmission line) Page 1 of 16

2 1. Background In order to enhance the level of cross-border electricity transmission between Nepal and India, a few 400kV transmission links have been identified for development. Cross-border links help Nepal import sufficient amount of electricity during dry season when hydro generation drops sharply while surplus amount of electricity generated from various hydro-plants during wet season could well be exported to the energy-starved Indian market. One of the links viz., Dhalkebar-Muzaffarpur, is already under execution as first cross-border extra high voltage link. As Dhalkebar-Muzaffarpur 400 kv link is found to be inadequate for cross-border power transfer when all the committed generation in Nepal is available around 2020, Government of Nepal (GoN) has proposed the establishment of second 400 kv cross-border line. The connection points of the proposed second cross border transmission line are Bardaghat in Nepal and Gorakhpur in India. The Asian Development Bank (ADB) has provided grant assistance under Project Preparatory Facility for Energy (PPFE) which will support preparation of detail project report (DPR) of Nepal-India Second Cross Border Transmission Line (Bardaghat-Gorakhpur 400 kv Transmission Line). Nepal Electricity Authority (NEA) is the implementing agency for this part of PPFE. In this backdrop NEA intends to procure the services of internationally reputable consulting firms ("the Consultant") having competent team of specialists to perform related route identification, detail survey, investigations, initial environmental examination (IEE), detail design of line and substation, and preparation of bidding documents. 2. Objective of the Assignment NEA intends to engage a consulting firm for carrying out the feasibility study of approximately 30 km long Nepal part of Nepal-India Second Cross Border 400 kv Transmission Line. The transmission line shall be routed from New Bardaghat substation (in Nepal) to New Gorakhpur substation (in India). Bardaghat-Gorakhpur cross border transmission link is proposed to be developed either as (i) a 400 kv transmission link with a back-to-back DC scheme at one end or (ii) a ±500kV bipolar HVDC link. These shall be referred to as the Transmission Options. The Consultant shall review all the available HVDC schemes (classical HVDC or latest HVDC Light, etc.) and recommend the most appropriate option, voltage level, conversion/inversion aspects, etc. based on the study of energy export possibility to India and other technical parameters such as losses, system stability and so on of Integrated Nepal Power System. The objective of this consultancy services is to conduct route alignment survey to fix the most appropriate route, carry out detail route survey, prepare plan & profile drawings, tower spotting, carry out design of towers and foundations, carry out design of substation expansion, prepare detail cost estimates, and conduct techno-economic feasibility. The objective also includes investigating the feasibility of alternative transmission technology and study of cross border energy markets. Page 2 of 16
