INTRODUCTION 1. Demand for electricity in India currently outstrips supply. Inadequate generation, transmission, and distribution, as well as the inefficient use of electricity, lead to shortages, particularly at peak times. The total national shortfall is estimated to be 8.3% of demand.1 Based on the 2001 census, about 44% of households do not have access to electricity. Recognizing that electricity is one of the key drivers of rapid economic growth and poverty reduction, the Government of India aims to meet electricity demand in full by 2012.2 Other objectives include providing all households with access to electricity within 5 years and increasing the per capita availability of electricity to over 1,000 kilowatt hours by 2012. 2. The substantial demand for electricity will be met mainly by the installation of new coal- and gas-fired thermal power stations and by hydropower. Particular emphasis is being placed on hydropower, but, even with the full development of all the feasible hydropower projects, coal remains the primary fuel for meeting existing and future electricity demand (footnote 2). 3. NTPC Limited (formerly National Thermal Power Corporation Limited) is currently implementing the Sipat Super Thermal Power Project (STPP) (stages I and II) and extending the Kahalgaon STPP into stage II. Power generation is scheduled to begin at the Sipat STPP stage II in June 2007 and at the Kahalgaon STPP stage II in November 2006. They will contribute an additional 4,480 MW of installed capacity to the Indian grid, making a substantial contribution to meeting the current shortfall of supply and to meeting the electricity supply targets set out in the Tenth Five Year Plan (2002–2007)3. 4. Environmental impact assessments (EIAs) were prepared for both projects, as required by government planning requirements, covering the construction and operation phases of each development. The Sipat STPP comprehensive EIA (March 1998) was initially prepared for a 3,000 MW project consisting of stage I (4 x 500 MW units) and II (2 x 500 MW units). The Project was subsequently revised to the current design of 2,980 MW, consisting of stage I (3 x 660 MW units) and II (2 x 500 MW units). Project environmental clearance was granted for stage I by the Ministry of Environment and Forests (MOEF) based on the original EIA assessment of 4 x 500 MW units given that the magnitude of each main impact was deemed to be similar for both plant configurations. The EIA addendum (May 2003) subsequently addressed the revised 1,000 MW stage II (2 x 500 MW), while also assessing the total cumulative impact of the entire 2,980 MW plant for most issues. 5. The Kahalgaon stage II EIA (2000) was initially prepared for a 1,320 MW project consisting of 2 x 660 MW units. The stage II project design was subsequently revised to 1,500 MW consisting of phase I (2 x 500 MW units) and phase II (1 x 500 MW units). Environmental clearance was granted by MOEF for the revised stage II phase I of the Project in 2001, based on the original EIA. Another EIA was then prepared for stage II phase II (1 x 500 MW units) in 2003, for which environmental clearance was granted on 20 May 2004. 1 Ministry of Power, 2006.

Sipat STPP approvals include MOEF environmental clearance for stage I granted on 13 January 1998 and stage II granted 8 June 2004, and a no objection certificate granted by the Chhattisgarh State Pollution Control Board (SPCB) on 6 January 2004. The Kahalgaon stage II approvals include environmental clearance granted by MOEF for stage II phase I on 13 June 2003 and stage II phase II on 29 May 2004.
