DRP NB 240423: The world is moving away from Big Dams: Are we?

This well substantiated report from Yale School of Environment this week shows that the end of the big dam era is approaching. The well argued report from Jacques Leslie uses the reports from UN University, International Renewable Energy Agency, Oxford University, Inclusive Development International, China, among others to show how the pace of construction of dams and hydropower projects and also pace of financing such projects have hugely reduced in recent years and decades.

Even the International Hydropower Association, sensing the change, is now advocating pump storage hydro rather than conventional hydro and that too off stream version, to complement the power from solar and wind. Emerging economics with rising cost of hydropower projects and rising cost of power from such projects compared to solar, wind (onshore and offshore) are a major reason for the massively slowing pace of new hydropower projects.

On Feb 15, 2023, Union Ministry of Power issued draft guidelines for Pump Storage Projects, inviting comments from stakeholders in 15 days to the email id – hydro2-mop@gov.in. The guidelines say that more Pump Storage Projects (PSPs) are required in view of increasing solar and wind power capacity connected to the grid, to stabilize the grid, store the power to make it available during non-solar and non-wind power hours and for peaking power, reactive power, etc. It describes the PSP as “clean, green, safe, and non-explosive” and “environment friendly” option. No studies or basis are provided for this sweeping conclusion.

Dam Floods, Failures and Disasters in 2022

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.
