III. LOHARINAG–PALA HYDROELECTRIC PROJECT 16
Designer: Voith Hydro (E&M Package)

Loharinag Pala Hydro Power Project is a run-of-the-river hydroelectricity generating project planned by the National Thermal Power Corporation (NTPC) Ltd to have an output capacity of 600 MW (150 MW x 4 Units). The project is located on the river Bhagirathi, the headstream of the Ganges River at Loharinag Pala, below the confluence of the Songad River, next to NH 108 in Uttarkashi District of Uttarakhand state, India. This is about 100 kilometres (62 mi) upstream of the Tehri Dam.[2]

The main project construction contracts were awarded and construction started in 2006,[3] however, work was stopped in 2009 after Professor G. D. Agrawal, one of India's eminent scientists,[4] came close to dying on the 38th day of his fast in protest of the blocking the headwaters of the sacred River Ganges.[5][6] Tarun Bharat Sangh, headed by Magsaysay award-winner, Rajendra Singh also played a pivotal role in stopping the project.[7] The project was officially scrapped in 2010.

The Loharinag-Pala project was one of several hundred dams and barrages planned or now being constructed by India, in the southern foothills of the Himalayas. Together they are expected to provide 150,000 MW of electricity for areas in which power cuts are frequent and demand is growing fast.[5]

Description

The Hydroelectricity project had been envisaged for installation of 4 generating Units of 150 MW utilizing a hydraulic head of 476.5 metres (1,563 ft) to have a maximum capacity of 600 MW. The facilities would include 4 vertical shaft Pelton wheel turbines. The generators would be of synchronous vertical shaft type. The generators would have capacity at a lagging power factor of 0.90, 3 phase, 250 rpm, and rated voltage of 11 to 18 kV. The generator transformer would be 4 nos oil forced air forced (OFAF) type with step-up voltage capacity of 400 kV. The estimate of Greenhouse gases (GHG) abatement in tonnes CO2 equivalent is 5,268,027 t (Starting from 2010). Host Country Approval Status was Approved.[8]

The Project Owner/Proponent was Mr. Piyush Pradhan, CDM Representative, Engineering Division, Project Engineering (Mech-CDM) (NTPC) Limited, NTPC Bhawan, Core-7; Scope Complex, 7-Institutional Area, Lodhi Road NTPC Bhawan, Scope Complex, New Delhi – 110003. The baseline methodology used for the project evaluation was ACM 0002: Consolidated methodology for grid-connected electricity generation from renewable sources – version 6; The latest version of the tool for demonstration and assessment of additionality (the additionality tool). The expected date for commissioning of the project was in the year 2010. Duration of the project activity is 21 years.[8]

Project land

For township Land at Matli, private land needed was 11.383 hectares (28 acres) and government land needed was 1.835 ha. The revised proposal for Section IV was submitted in DM Office on 23-03-06. The Proposal was sent by DM, Uttarkashi to GoUA.now with discontinuation of the project by orders of India govt. the land acquisition is not being done.

For township land at Central Industrial Security Force (CISF) Colony at Kyark, private land needed was 9.979 hectares (25 acres) and government land needed was 1.436 hectares (4 acres). The proposal for Section IV was submitted in DM Office on 17-03-2006. The Proposal was sent to GoUA by DM, Uttarkashi but now not required as project has been discontinued by India government.

The project site starts from confluence of the Songad river on the Bhagirathi River in the Garhwal Himalaya to 18 kilometres (11 mi) down stream at Thirang gad confluence with Bhagirathi river. The barrage site is next to NH 108 at Loharinag Temple. The Project has a mountainous catchment area of 3,316 square kilometres (1,280 sq mi), of which 1,849 square kilometres (714 sq mi) (56%) is covered in snow or glacier. The source of the Bhagirathi is about 82 kilometres (51 mi) above the barrage.[9]

Update

Work on the Loharinag Pala Hydro Power Project was stopped after one of India's eminent scientists came close to dying on the 38th day of his fast in protest of the harnessing of the river Bhagirathi, a source stream of the Ganges River.

Professor G. D. Agrawal (b. 1932), former dean of the Indian Institute of Technology Kanpur, in the first week of March 2009 called off his second fast in a year against Himalayan dam projects, after the Indian government agreed to speed up its inquiry into how electricity could be generated without the flow of the Ganges being impeded. The free-running of the river is a crucial element of its sacred status.

Before his fast began in January, Agrawal said,: "The water ...(of the Ganges) is not ordinary water to a Hindu. It is a matter of the life and death of Hindu faith".[5]

In August 2010, the Group of Ministers discontinued the project.[11]

Impact

Addition of 2,353.37 GWh of electricity generation to the Northern region grid would be the main measurable benefit of the Project. The average unit cost of electricity generated by the plant would be about Rs2.00 (US$0.0455) per kWh. The project appears to be economically viable under normal operating conditions. This table power supply is crucial for increased employment balanced growth in the area. The unit power cost from plants like the Loharinag–Pala HEP is less than the cost of private on site generation of electricity due to less-efficient technology and high fuel cost used of private off-grid generation.[12]

The Environmental impact statement (EIS) prepared by the NTPC indicates the main adverse environmental impacts of the project will be changes in river hydrology, a decline in the quality of aquatic ecosystems, loss of agricultural and forest land, and resettlement. Impacts on the rivers will be mitigated by the release of a 0.85–1.1 m3/s minimum environmentally acceptable dry season flow from the Loharinag–Pala dam, the release of monsoon season flushing flows, and yearly restocking of rivers above and below the barrage sites with snow trout.[13]

The loss of private agricultural and forest land has been or will be mitigated by the acquisition of private land at an above-market rate. The social impact of the projects will be mitigated by NTPC’s resettlement and rehabilitation procedures, with fair compensation being paid by NTPC.[14]

Also the owner of the project is not been fair on their contractual part as of not clearing the situation of uncertainty prevailing from so long duration to their contractors causing high stakes and risks at contractors end.
