Himachal hydel projects
Rivers siphoned off
With water being sent into tunnels under mountains to run turbines of hydropower projects, nearly the entire length of the Sutlej in the state and parts of other major rivers would not be seen above surface by 2022, severely impacting the local populations and environment

The
roaring rapids of the Sutlej are well on the way to be silenced and breathtaking sights of the life-sustaining river wiped off the mighty Himalayas in Himachal if all hydroelectric projects proposed are commissioned by 2022, as planned. Thus far, there is little reason why they would not.What will remain is a dry riverbed, dotted with manmade reservoirs built to divert water into long tunnels bored under the towering mountains for power generation. When the full potential of all projects is attained, they would generate a massive 10,723 MW (approximately equal to all of Punjab’s current estimated requirement). The series of hydroelectric (hydel) projects will ensure that the 230-km stretch of the river from Shipke La — where it enters India from China — to Koldam will have 135 km of tunnels, which will effectively kill 160 km length of the river. The remaining 70 km will be subsumed in reservoirs. The longest 38-km twin tunnels planned for a 775 MW project at Luhri will cut out 48 km of the river, and the longest reservoir, Kol Dam, will take away 37 km. Two major projects already completed — the 1,500-MW Nathpa Jhakri and 1,200-MW Karcham Wangtu — have reduced the river to a trickle in the area, except the four months of monsoon.
Independent power producers are opposing the Centre’s decision to make a riparian distance of 1-2 km between two projects mandatory. The fate of the Ravi (3,011 MW), Chenab (3,132 MW) and the Pabbar (887 MW) will be no different, as the government has assigned projects on these without bothering about the riparian distance. Only the Beas (5,712 MW) river will be spared to an extent, as no projects have been planned between Aut and Manali. Going nocturnal The Central Electricity Authority (CEA) has allowed independent power producers to indulge in what is called “hydro-peaking”, which will cause rivers to run only at night during the lean winter months, when the discharge in rivers declines to about 20 per cent. In this, the “run of the river” projects will store water during the day, and release it in the evening to run the turbines, when the demand for power peaks. As a result, rivers will remain virtually dry during the day. Small is big loss The cascade of 648 small and big projects planned will have serious implications for the hill people, who have already set off agitations across the state. While large projects with big reservoirs are being opposed by environmentalists all over the country, in Himachal small projects too are seen as a curse by villagers. The reason is most villages are perched on hillsides, which are served by streams — large rivers run at the bottom of valleys between hills. Nearly 400 small projects (up to 5 MW) are coming up on streams and rivulets, which cater to villagers’ needs of drinking water and irrigation. The streams also have religious significance, with funeral grounds located on their banks. People are not much dependent on the main rivers. The Centre had framed a policy to provide subsidy on small projects for harnessing streams for the benefit of local people. However, the projects turned out to be a goldmine for private companies — mostly from outside the state — and a curse for villagers. They allege overexploitation, citing more than six projects planned on certain streams, such as the Neogli Khad (eight projects) in Shimla and the Chanju Nullah (six) in the ecologically fragile Chamba. In Sweden, 20 per cent of the hydel potential has been left unexploited to protect the environment. Villagers also say that the long tunnels under the mountains have disrupted the natural aquifers, as a result of which natural springs are drying up, leading to shortage of water for drinking and irrigation. This has affected apple orchards in Kinnaur. Him Dhara, a Himachal-based environment action group, obtained data under the Right to Information Act from the Irrigation and Public Health Department, which revealed that 43 out of 167 water sources had dried up in villages affected by the Karchham Wangtoo project, and discharge in another 67 has gone down. R.S. Negi, a retired IAS officer who has set up an intellectual group Him Lok Jagriti Manch to create awareness, says the ecologically fragile alpine zone (above 7,000 ft altitude) should be spared, and riparian distance of 5 km or more should be maintained between projects to sustain livelihood and aquatic life. Locals fighting back The numerous projects coming up on small streams has villagers up in arms. Lal Chand Katoch of the Jal, Jungle and Zameen Bachao Samiti, who has been leading movements since 2003 in Kullu, alleges that instead of protecting the interests of the people, the government is backing private companies, which use muscle and money power to crush resistance. He has moved the high court to “save” the Haripur stream from a 1.5 MW project. The stream serves 19 villages, including 12 watermills and several fish farms, including an Indo-Norwegian Hatchery project, besides agriculture. Religious sentiments of people are also hurt when projects are allowed on sacred sites such as the Jogini waterfall, he adds. In Chamba, the Saal Ghaati Bachao Sangharsh Morcha has been fighting against a 4.5 MW project on the Hul stream. Rattan Chand, a leader of the Morcha, says nearly all big and small streams, except the Hul, in and around Chamba have been hit by projects. Manshi Asher, an environment researcher working with the Him Dhara, says the government must review the allotted projects on which work has not started yet. The cumulative impact on environment and people should be taken into consideration.
Environmental impact n
6,300 hectares of forest land diverted for projects and transmission lines. Lakhs of tress axed.n
Deforestation and sending water into tunnels increases ambient temperature. n
Debris from blasting and construction is dumped on slopes, damaging vegetation. n
Roads through virgin forests and reservoirs lead to fragmentation of wildlife habitat. Visheshwar Negi, a resident of Reckong Peo, says debris has buried pastures and disrupted traditional routes of shepherds. n
Apple production going down in certain areas, despite new plants being planted.
Policy decisionsSeveral policy decisions have been taken to address environmental issues. Cumulative environment impact assessment is being carried out for each river basin and the catchment area treatment plans have been revamped with focus on bio-engineering and provision for incentives to the local people in securing watershed protection. The mandatory environmental discharge to be maintained at all times in the rivers is proposed to be increased from 15 to 20 per cent. Sudripta Roy, Chief Secretary (Additional Chief Secretary, Environment and Forests, till recently)
Matter of benefitsProtests against various projects are not entirely due to the likely adverse impact. People who are not getting any direct benefits are also stalling work. Recently it has been decided that power companies will also distribute among the affected local residents money equivalent to the worth of 1 per cent of the power generated by a project. This will go a long way in placating people. Deepak Sanan, Principal Secretary, Power
Maintain balancePrecious natural resources such as land, forests and water are being plundered in the name of harnessing the hydropower potential. A balance is required as projects cannot be allowed at the cost of environment and livelihood of the people. Kulbhushan Upmanyu, convenor of the Himalaya Niti Abhiyaan (umbrella body of state NGOs pursuing environment issues)
One thing that goes in favour of power projects is that they are a major source of revenue for a fund-starved state. The Himachal Government has sound economic reasons for exploiting its hydropower potential, a major source of non-tax revenue. The revenue from the power sector had shot up from Rs 29.6 crore in 2003-04 to a whopping Rs 1,255 crore in 2008-09, before falling to Rs 1,050 crore in 2011-12 due to decline in market rates. As per projected figures, the projects already allotted with an aggregate capacity of 12,798 MW – which are at various stages – will on completion by 2022 fetch the state 16,270 million units of free power per year as royalty. At current rates, that is worth Rs 4,393 crore. The best part of this income is that it comes without taxing the people, which is a bonus for the government. To counter the resistance to hydel projects, the government has made spending 2 per cent of the project cost for the benefit of the affected people mandatory.
