'Pumped storage projects ecologically damaging, prioritize battery energy storage systems'

By A Representative
 
In a letter addressed to the Secretaries of Power, New & Renewable Energy (N&RE), and Environment, Forest & Climate Change (EF&CC), climate and energy policy analyst Shankar Sharma has made a strong case for prioritizing Battery Energy Storage Systems (BESS) over Pumped Storage Projects (PSP) in India’s quest for sustainable energy security.
Highlighting the growing environmental opposition to large river valley PSPs such as the 2,000 MW Sharavathi Valley project in Karnataka, Sharma emphasized the clear advantages of BESS in terms of land use, cost, and ecological impact. He noted that BESS requires only about 0.1 to 0.5 acre per MW, compared to hundreds of acres of forest land needed for PSPs. Furthermore, the cost of BESS in India is estimated at ₹2.20–₹2.40 crore per MWh, which, he argued, is justified given its minimal ecological footprint and flexibility of deployment across the grid.
Sharma pointed out that BESS can be installed at substations and distributed locations without affecting wildlife sanctuaries or cutting forests. In contrast, PSPs, particularly in fragile ecological zones, can lead to irreversible damage to biodiversity and water systems.
He also cited recent developments to support his argument, including large-scale BESS tenders floated by Gujarat and Maharashtra (each for 2,000 MW/4,000 MWh), and regulatory approvals for similar projects in Karnataka and Kerala. International advancements, such as Australia’s moves towards a 100% renewable-powered grid with long-duration BESS, further underscore the relevance of battery storage as a key component of the future energy mix.
Sharma expressed concern over the lack of rigorous policy-level evaluation of PSPs versus BESS in India. He criticized authorities for proceeding with ecologically sensitive PSP projects without conclusively establishing their necessity or exploring BESS as a viable alternative.
Calling for an immediate pause on the clearance process for the Sharavathi Valley PSP and similar projects, Sharma urged the Ministry of Environment, Forest & Climate Change (MoEF&CC) to withhold permissions until a comprehensive, national-level comparative policy on PSP and BESS is developed.
He concluded by stressing that energy planning must align with ecological wellbeing, and that technology choices like BESS offer a pathway that avoids environmental degradation while meeting the country’s power needs.

The making of a self-made woman: How eighty sheep changed everything for Kalawati Ninama

By Vikas Meshram*  About forty-two kilometres from Rajasthan's Banswara district, in the tribal heartland of Ghatol block, lies the small village of Ubapana. This is where Kalawati Ninama, her husband Dhulji, and their four children make their home. Their days unfold much like those of their neighbours—bustling mornings, long hours of farm labour through the afternoon, and evenings spent tending livestock. For this family, farming and livestock were once simply a means of putting food on the table. Today, they have become the sturdy foundation of something far greater: genuine self-sufficiency.

Ahmedabad world’s least climate resilient major city: AlphaGeo study

By Rajiv Shah  A new study has ranked Ahmedabad as the least climate-resilient major city in the world , highlighting a dangerous gap between the city’s extreme physical vulnerability to climate hazards and its capacity to adapt. Cited by The New York Times , the analysis, conducted by geospatial artificial intelligence firm AlphaGeo , places the Indian city at the top of a list of global urban centres most exposed to climate risk.

India has spent billions on skilling. Where are the jobs?

By Vikas Gupta   India loves the photograph of a certificate ceremony. A minister on a stage. A banner bearing the word “skill.” Young people holding folders that promise a future. It is a reassuring image because it tells us the problem has a manageable answer: train the young, make them job-ready, and work will follow.
