Assam Transmission System Index Assam Electricity Grid Corporation Limited 1 EXECUTIVE SUMMARY The Government of India and Government of Assam have requested Asian Development Bank (ADB) to provide US$200 million loan funding via a Multi-tranche Financing Facility (MFF) to support continued investment in power sector in the state of Assam. The project is implemented in 3 Tranches viz. Tranche 1, Tranche 2 and Tranche 3. The original Loan Agreement (LOAN NUMBER 2592 - IND) for Tranche 1 was signed on 15 February 2010 between Government of India and Asian Development Bank (ADB). As per the original Loan Agreement ADB has agreed to make to the Government of India, GOI (Borrower) the loan on the terms and conditions set forth in the Loan Agreement, but only on the condition that the proceeds of the Loan be made available to the State and through the State (Government of Assam, GOA) to Assam State Electricity Board (ASEB). ASEB was the Executing Agency (EA) for all the three tranches. The Borrower in its letter of 11th June 2014 has informed ADB of the dissolution of erstwhile EA for the Projects i.e., the ASEB and its place of its successive entities namely the Assam Power Generation Corporation Limited (APGCL), Assam Electricity Grid Corporation Limited (AEGCL) and Assam Power Distribution Company (APDCL). The Borrower further requested ADB to accordingly make the relevant change in the EAs as AEGCL for Tranche 1 and 2, and APDCL for Tranche 3.
