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.

DRP NB 191222: Question marks over viability of pump hydro projects

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”.
