Indian government continues to have very ambitious hydropower targets, even though all the evidence suggests why we should be reviewing it. As per Central Electricity Authority, India has 42641 MW of installed capacity from large hydropower projects at the end of Dec 2015. The installed capacity from projects below 25 MW is not included in this figure.
Capacity addition in 2015: Troubled projects
During 2015, India added 1824 MW of large hydropower capacity. Some of the important projects commissioned during the year include: 800 MW Kol Dam in Himachal Pradesh (one unit each on 30.03, 31.03, 10.04, 12.06), 450 MW Baglihar II in Jammu and Kashmir, 80 MW at Lower Jurala Project in Telangana, 330 MW Srinagar HEP in Uttarakhand and 96 MW Jorethang Loop Project in Sikkim. The first project is in Central Sector, next two in state sector and last two in private sector. Except for the 80 MW from Lower Jurala, rest of the capacity is all in Himalayan states.
All of these projects have had a very troubled track record and most continue to face serious problems even after commissioning.
The reason for going into above details about projects commissioned in 2015 is to illustrate how seriously problematic our decision-making has been, even in these times. Evidently, there is a need to overhaul decision making surrounding hydropower projects in vulnerable areas which face local opposition.
Are we paying any attention to this? Unfortunately, no.
To illustrate, let us look at the decisions taken by the Union Ministry of Environment and Forests’ Expert Appraisal Committee on River Valley and Hydropower Projects. All hydropower projects above 25-50 MW need clearance from this committee, as also all large irrigation projects.
EAC decisions in 2015
The EAC has had zero rejection rate and has been clearing huge number of dams and hydropower projects, far exceeding the need, justification or carrying capacity of the river basins, with very little attention to the prudent environment governance.
During the year 2015, EAC continued this tradition of zero rejection rate! Even for the couple of projects that it did not agree to approve immediately, it asked for a reformulate of the proposal, keeping the options open.
During 2015, EAC recommended environment clearance to twelve projects; six of them were hydropower projects, all from Arunachal Pradesh. The biggest of them, the Kalai II project of 1200 MW showed how starkly flawed were the EAC decisions. Rest of the six were irrigation projects, including two controversial lift irrigation projects from Maharashtra (Shirapur and Krishna Marathwada) and one irrigation project each from Tamil Nadu, Odisha, Chhattisgarh and Telangana.
It should be added here, as a reminder to the decision makers, that the work at Lower Subansiri Hydropower project continued to remain stalled for the four full years as on Dec 16, 2015. This is an indication, if one was required, to show how costly the consequences of wrong decisions can be.
The EAC cleared 21 projects for first stage environment clearance, including 9 hydropower projects, two each from Arunachal Pradesh, Uttarakhand, Himachal Pradesh, Jammu & Kashmir and one from Sikkim. It also cleared four irrigation projects (one each from Rajasthan, Bihar, Jharkhand and Odisha) and eight lift irrigation projects (five from Karnataka, two from Maharashtra and one from Uttar Pradesh). It also okayed 16 applications for extension of validity for the first stage clearance, the validity, which is supposed to be for 2-3 years, went on for 4-5 years!
The EAC discussed Cumulative Impact Assessments (CIA) of Tawang, Subansiri, Siang, Dibang and Kameng river basins, all in North East India this year. Worrying, during each of these discussions it eventually approved shoddy and seriously problematic CIAs, diluted its own recommendations and refused to understand the concept of conflict of interest.
EAC did say no to first stage environment clearance to Purthi HEP in Lahaul and Spiti district in Himachal Pradesh, but gave its ok when it came back with a slightly different configuration. It did say no to extension of TOR to Lara Sumta and Sumta Kathong HEPs, but suggested they can apply afresh! It has not yet cleared Ken Betwa, Etalin and Pancheshwar, but has not said no either to any of them. It did mention SANDRP submissions dozens of times, but did not invite SANDRP, or any other group to the EAC meetings even once where SANDRP submissions and developer response were discussed. There has never been a point-wise discussion in the EAC about the merits and demerits of the developer’s response. Just to illustrate how problematic has the EAC decisions have been, see our blog about the 86th meeting of EAC held in August 2015.
All this only goes to illustrate how seriously problematic are our decisions about dams and hydropower projects.
Generation performance of hydropower projects
The basic purpose of building hydropower projects is generation of electricity, let us see how India’s hydropower projects perform in 2015. During the year, with total installed capacity of 42641 MW as on Dec 31, 2015, India’s large hydropower projects, as per the data from Central Electricity Authority, generated 129.11 BU (Billion Units, one unit equals one kilowatt hour), compared to 130.8 BU in 2014. So even though installed capacity in 2015 went up by 1824 MW, generation went down by 1636 Million Units! Our earlier analysis has shown how the returns from hydropower projects in India are diminishing in different respects. The trend continues in 2015.
It may be added here that USP (Unique Selling Proposition) of hydropower projects is that they can provide peaking power ( power supply in the hours when the demand is highest). There is no agency that is either monitoring or trying to optimize peaking power from hydropower projects. However, let us take a snapshot of this situation. A review of the daily Power Supply reports of the Northern Region Load Despatch Centre shows that on Dec 31, 2015, Northern region had peaking shortage of 1529 MW. Northern Region, incidentally, should give us the best illustration in this regard since it has, at 18815 MW, the highest hydropower capacity among all regions of India.
On Dec 31 2015, hydropower projects were providing 10041 MW of generation during peak hours, and 2446 MW generation during off peak hours. So net peak load provided by hydropower projects on Dec 31, 2015 was 7595 MW, which is just 40% of the hydro installed capacity of 18815 MW in the region. This snapshot tells us that on Dec 31, 2015 (incidentally, the rivers have minimal flows at this time and hence all the more reason even for run of river projects to operate in peaking mode) about 60% of the hydropower capacity was NOT providing peaking power, which it was supposed to do!
It may be added that Northern region had only 1529 MW of peaking shortage, which could have been easily provided by the more optimum performance of these projects. It also tells us that as far as peaking power requirement is concerned, we do not really need more hydro since the current capacity is sufficient to cater to our peaking needs, if operated optimally, in a manner that hydropower projects are supposed to operate! Even as a snapshot, this tells us a lot!
Hydro disasters in 2015
The year 2015 showed increasing disasters related to hydropower projects. Such disasters included the one at Chutak Hydropower project in Kashmir, Sorang hydropower project in Himachal Pradesh, Vishnuprayag hydropower project in Uttarakhand, Multiple disasters in Kinnaur district in Himachal Pradesh, among others. At Rishikesh in Uttarakhand, hundreds of people had narrow escape in Dec 2015 due to sudden release of water from Tehri Dam, as alleged by the news reports. The High Court of Himachal Pradesh, in Jan 2016, while announcing compensation to families of the students who lost their lives due to Larji Dam mishap in Oct 2014, called Larji Dam a Killer.
This year end review of hydropower projects in India tells us that our decision making surrounding hydropower projects is flawed and that we can and must change the way the decision making system in functioning.
On the other hand, power generation performance of hydropower projects continue to diminish and even for peaking power requirement, we do not really need more hydropower.
It should also be added that as large number or organisations from all over the world wrote to the United National Frame Convention on Climate Change, Large Hydropower must not be considered as a solution in the climate change context.
