3 PREFACE Present Review Milestone Achieved During April, 016 to June, 016. Sanctioned Projects for 1 th Plan & Beyond Status of Sanctioned Projects for 1 th Plan & Beyond Financial Status of Projects for 1 th Plan & Beyond This quarterly review covers the period from Apr, 016 to June, 016 and is 85 th in the series. The objective of this review is to provide up to date information in respect of Hydro Electric (HE) Projects under construction/ implementation in the country. The review covers HE projects under construction likely to give benefits in 1 th Plan & beyond. This quarterly review has been brought out by CEA on the basis of data received from various project authorities, visit made to different HE projects and discussions held with the executing agencies and suppliers of equipments from time to time. Details of HE Projects Rolled/Commissioned during the Quarter is indicated in Chapter-1. A list of sanctioned HE projects for 1 th plan and beyond is indicated in Chapter 5. Broad present status of sanctioned HE projects for 1 th plan and beyond is given in Chapter 6. Financial status of HE projects supplied by project authorities (unaudited) 1 th plan and beyond is given in Chapter 7. Status of Environment & Forest Clearances of H.E. Projects for 1 th Plan & Beyond Dates of Award of First Package Ordering Status of TG set. The status of Environmental & Forest clearance of HE projects for 1 th plan and beyond is given in Chapters 8. The date of award of First Package for HE projects under execution is indicated in Chapter 9. Details of Ordering status of TG Set for HE projects under construction is given in Chapters 9.1 and 9.. 1

4 Details of Award of various packages Status of Financial closure of Private Sector Projects Time & Cost Over-run of Ongoing Hydro Projects Exclusions The details of package, and package of HE projects for benefits during 1 th plan and beyond has been given in Chapter 9.3. Details of financial closure of Private Sector HE projects for 1 th Plan and beyond is given in Chapter-10. The Status of Time & Cost Over-run of HE projects under execution for benefits during 1 th plan and beyond is given in Chapter 11 The review does not cover HE projects categorised as renewable, each with a total installed capacity of 5 MW and below, as these schemes come under the purview of Ministry of New & Renewable Energy (MNRE). Any suggestions/feedback for further improvement in the quarterly review shall be appreciated. The report is in fulfilment of CEA s obligation under Electricity Act, 003.
