, 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".
In August 2010, the Group of Ministers discontinued the project.
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.

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
common snowtrout.
[(ADB) p. 28]
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.
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.
