Summary of Public Hearing 64 I. INTRODUCTION 1. Jhajjar Power Limited (JPL), a 100% subsidiary of CLP Power India Private Limited (CLP PIPL), which in turn is a 100% subsidiary of CLP Holdings, is developing the Jhajjar Thermal Power Project (JTPP). Under a reform program, the Government of the state of Haryana divided the electricity business owned by the Haryana State Electricity Board into three components: generation, transmission, and distribution. To meet the growing power and energy deficit, the Government of Haryana promoted the Project and subsequently awarded it to CLP PIPL through competitive bidding under the Electricity Act 2003 1 and standard bidding guidelines issued by the Government of India. 2. The Project comprises the construction of a supercritical 2, coal-fired power plant with a total capacity of 1,320 megawatts (MW). The plant will consist of two 660 MW units that will run on coal supplied by rail from India’s North Karanpura coal fields, which are operated by Central Coalfields Limited (CCL). The Project was awarded to CLP PIPL on a build, own, and operate (BOO) basis. Equipment sourcing through various packages has been finalized with suppliers and construction will commence in March 2009. The plant is scheduled for full commercial operation in April 2012. 3. The Project is located near Khanpur village in Jhajjar district in the state of Haryana. The site is close to the Jharli railway station on the Dadari–Rewari section of the North Western Railway (Map 1). The project site covers 494.1 hectares (ha) of low-yield agricultural land in the villages of Khanpur Khurd, Khanpur Kalan, Wazidpur, and Jharli. The project area includes 214.5 ha for plant and equipment, and a switch yard, coal handling system, and related plant; 109.3 ha for ash disposal; 137.0 ha for the greenbelt and water storage facilities; and 33.2 ha for the township. The project site is located on Jhajjar–Matanhel–Kanina district road, which is 38 kilometers (km) southwest of Jhajjar town. 4. An environmental impact assessment (EIA) for the Project was completed by MECON Limited (MECON) in January 2008 based on terms of reference approved by the Ministry of Environment and Forests (MoEF) on 7 October 2007. As part of the EIA process, a public hearing was held on 29 October 2007 and further consultations were subsequently conducted in local villages. The Project received environmental clearance from MoEF on 24 April 2008 based on the EIA. An application for the alteration of the MoEF environmental clearance has been submitted to MoEF to permit the use of supercritical boiler technology. All other key clearances and permits from national and state authorities required for construction and operation have 1 An Act promulgated by the Government of India to consolidate laws relating to the generation, transmission, distribution, trading and use of electricity and generally for taking measures conducive to development of the electricity industry, promoting competition therein, protection of interest of consumers and supply of electricity to all areas, rationalization of electricity tariff, ensuring transparent policies regarding subsidies, promotion of efficient and environmentally benign policies, constitution of Central Electricity Authority, Regulatory Commission and establishment of Appellate Tribunal and for matters connected therewith or incidental thereto. 2 The boiler technology options available for large, pulverized coal-fired power plants are subcritical, supercritical, and ultra-supercritical. Subcritical plants operate at steam pressure of less than 19 megapascals, where the steam is a mix of liquid and gas, and drum-type boilers are used. Supercritical plants operate at steam pressure of more than 22.1 megapascals and use once-through boilers. The steam at 22.56 megapascals and 374.15°C is said to be in a critical state. Ultra-supercritical plants are about 2% to 3% more efficient than supercritical plants. These plants operate at even higher steam pressures of about 30 megapascals and steam temperatures of about 600°C. Supercritical technology is becoming standard practice in the power industry in developed economies for
