In addition to India, the local people in Himalayan countries of South Asia have been resisting against the hydro power projects. These countries have also been facing accidents and disasters caused by the hydro power projects. At the same time, the increasing construction as well as operational cost and climate change threats have been making the future of hydro power projects risky and uncertain in the region. This annual overview highlights the hydro power projects related accidents, disasters and concerns in South Asian countries.

People of at least four states are opposing hydropower projects that the central and state governments are pushing, ignoring all the ground realities. In Uttarakhand, the Joshimath residents are on roads to wake up the government that seems deaf to their protests due to their houses cracking and land subsiding due to the tunnels being blasted for hydropower projects and Char Dham highway being built ignoring the voices of not only the affected people, but also the experts.

In Arunachal Pradesh, people have been writing to the central govt authorities against the Etalin and Dibang projects being pushed in Dibang valley of Brahmaputra basin.

In Himachal Pradesh, the people of Kinnaur and Lahaul Spiti districts have made it an election issue the destructive hydropower projects being pushed there both by the state and central governments.

In Andhra Pradesh too people have been protesting against the pump storage projects being given permission in schedule tribe areas without their prior informed consent and ignoring the statutory requirements.

2022 is thus ending with people’s active protests across the country against destructive, disaster prone and unviable projects being pushed against their wishes and in violation of any proper consultations or even any credible impact assessments. In the escalating impacts of climate change, these projects are even more problematic as they not only worsen the adaptive capacity of people and invite more frequent, intense and spread of the disasters, but they also destroy the mitigation tools like forests and flowing rivers. This when all these projects are not even economically viable, and when better, cheaper options are available. It would be best if sooner the government listens to the people and stop pursuing such projects.

2022: Accidents & Damages related to Hydro projects in India

December 24, 2022December 30, 2022 SANDRPLeave a comment

In this annual review, SANDRP compiles the hydro power related accidents, disasters and damages in North West and North East Himalayan states during 2022. It also covers relevant reports revealing gradual decline in power generation by hydro power projects amid growing concerns over physical and financial viabilities of new projects. There are also reports highlighting the looming climatic and geological threats over these projects. It is good to see that taking lessons from Chamoli disaster in Feb. 2021, NDMA has officially asked central govt not to rely on hydro power.

In previous parts of yearend roundups, we have covered (1) Dam induced floods & damages, (2) Fly ash dam breach incidents, (3) Impact of floods on Polavaram project, (4) People’s resistance against dams and hydro projects. Please see links for reports tracking hydro power projects related accidents and disasters in 2021 and 2020.

There have been many instances of opposition by local people, organizations and experts against unviable hydroelectric power (HEP) and destructive dam projects in 2022. Such instances of the resistance from across the country have been successful in a number of ways including leading to the funding agencies, corporate houses and government agreeing to withdraw from the project in many cases. This overview presents top ten stories highlighting successful opposition to hydro and dams projects in 2022 in India followed by some relevant reports on the issue. In first part of the annual overview, SANDRP has tracked the dam failures and dam induced floods incidents in India in 2022, along with separate report on unraveling of Polavaram project and another one on breaches of fly ash dams.

Dam Disaster

2022: When Polavaram project further unraveled

December 20, 2022 SANDRPLeave a comment

Polavaram is the largest and costliest big dam project under construction in India currently, though not much has been written about this projects and its impacts in mainstream in India. The project was given various clearances through a manipulated process, basic studies were not done before clearing it. Several petitions are pending before the various High Courts and the Supreme Court of India, but the project is allowed to go ahead without resolving them or the inter-state issues. A number of issues related to the project has been unravelling over the years and in 2022, the project further unraveled as the news reports compiled here reveal.

A snapshot of the status at Polavaram Project: The downstream coffer dam is damaged, the Gap 1 and Gap 2 of the Dam are yet to be constructed, the 1.7 km long Diaphragm wall of the ECRF dam is submerged in flood waters, it was earlier damaged (scoured at two places over an an area of 200 m X 200 m) in 2019 floods implying additional expenditure of Rs 600 cr, the water flow at the dam site on July 15, 2022 was highest since 1920 for July, the assessment of the earlier damage to the diaphragm wall and future options that was underway when the floods struck in the second week of July 2022, had to be stopped while still incomplete, the rehabilitation colonies have been submerged as the engineers assessment proved wrong about their elevation. There is an uncertainty on the structural stability of the other facilities of the irrigation project due to incomplete construction of the main dam, as it is receiving an unprecedented inflow. The height of the upper Coffer dam was increased by 1 m to 44 m between 17 and 19 July, 2022, in the middle of high floods, but that had impact on upstream Telangana and they opposed that this was done without consulting them.

2022 Fly ash dam breaches in India

December 19, 2022 SANDRPLeave a comment

(Feature image:- This is the second time in the six months that Rautdih village has become inundated by the breach of ash pond embankment in Bokaro. ToI, Oct. 09, 2022)

Most mining companies make dams to store the semi solid slurry waste from the mines. Similarly most thermal power projects have fly ash dams to store the fly ash slurry. These dams store highly toxic slurries but there is little happening by way of regulation, monitoring or compliance at design, construction or operation level. Many of these dams breach or overflow, leading of release of the toxic slurry in the downstream areas. These dams do not even come under monitoring of Central Water Commission or under the dam safety act passed by the parliament. Despite accidents happening with huge adverse consequences, there is no accountability.

In this report, we have compiled the instances that we could locate about breaches of such dams in 2022. We earlier wrote about the Singrauli instance in April 2020 and in the 2019 SW Monsoon dam breach compilation report.

The question marks over viability of huge number of pump storage hydro projects (PSHP) being pushed forward in India currently were flowing in the rivers for long. This week, Moody’s investors Service (MIS) seems to have strengthened this after it downgraded Greenko Energy Holdings’ corporate family rating. It may be noted that Greenko is the biggest investor in PSHPs in India from private sector and a major part of Greenko’s new investments are in PSHP.

This makes the implications of MIS’s downgrade all the more interesting. MIS has noted that PHSPs are capital intensive and each PHSP will generate cash flow only after at least 2-3 years of construction (in reality it can be much longer than 2-3 years, the operative phrase here is at least). It also noted that the additional debt to be raised from Greenko’s capital spending, coupled with a rising interest environment will put further pressure on “GEH’s already weak financial metrics” and that Greenko’s high financial leverage due to its substantial capital spending program will keep its financial metrics below its downgrade trigger “for an extended period of time”.

Dam Floods, Failures and Disasters in 2022

December 17, 2022December 30, 2022 SANDRPLeave a comment

This annual overview highlights the dam induced flood disasters, dam failure incidents in India during 2022. This year, the massive floods in Godavari have exposed the flood vulnerability of giant projects like Polavaram and Kaleshwaram. Also there have been multiple dam failures and dam induced floods in Madhya Pradesh, Tamil Nadu and Kerala. In absence of coordination and data sharing Hirakud induced floods in Mahanadi basin have affected several villages in Odisha and Chhattisgarh. There have been several instances of unscientific operations of dams and the operators continue to hide behind TINA (There Is No Alternative) excuse. The functioning of CWC as key flood forecasting and management agency has not shown any significant improvement. However, now it has accepted that faulty dam operations can lead to flood in downstream areas. Please see links to our 2018, 2019, 2020 and 2021 annual compilations on the subject.

In the leaning golden sun, 65 year old Hari Ganpat Nikam dived like dolphin under a wooden contraption in the Vashishti River. He emerged a whole minute later bearing a beautiful woven basket, his right hand placed firmly on its mouth. As he brought the basket closer, he gradually removed his hand. Inside, tens of small fish and crabs shimmered in the evening light.

Tonight’s fish curry was sorted.
