Indian authorities 'evading' discussion on battery energy storage system

By Shankar Sharma* 

In the larger context of the ever growing need and importance of renewable energy sources for a sustainable energy/ electricity sector in our country, the critical role of energy storage systems, especially the battery energy storage system (BESS), is being emphasised frequently at the global level, such as the one by the International Energy Agency (IEA). Unfortunately, our authorities in India seem not to attach the same level of importance, which the BESS deserves.
Much of the discussions in our country, if any, on the energy storage systems, seem to focus on pumped storage hydro power and large scale transfer of power across the regions through high voltage lines. 
But such discussions never seem to take cognisance of the enormous ecological and social costs/ consequences of these two technologies to the larger society, and they also seem to provide only a passing mention of BESS, despite the fact that BESS, as a technology, has enormous significance for our country in its purported smooth transition to green & sustainable energy scenario. 
 Instead of considering how to make BESS a widely used and techno-economically attractive technology, the concerned authorities/ entities/ individuals seem to focus only on the nascent problems associated with such an emerging emerging technology. The fact that many countries, such as Australia, and large provinces like California, have already deployed massive capacities of BESS, and are reaping the associated benefits are rarely mentioned in such discussions.
A recent Supreme Court judgement on the threats to the highly endangered species of Great indian Bustard due to a few high voltage lines proposed in their unique habitats in Gujarat and Rajasthan to evacuate power from a few large size solar/ wind power parks, should have made our authorities to diligently review the recent past policies associated with the planning of a large number of high voltage power lines all over the country; including the ecologically sensitive areas such as WildLife Sanctuaries.
At a high level, there is a need to objectively review the very need for so many additional power lines, especially those dedicated for solar and wind power parks, and those routed through high value forests. 
There is a need to review the need for so many additional power lines, especially those routed through high value forests
Such an objective review will enable our planners to avoid many of these lines, and most of the pumped storage hydro project proposals, if the critical relevance of distributed kinds of renewable energy sources to our country, such as roof-top solar power systems are optimally harnessed.
The apparently evident reluctance of our authorities to objectively take into account such multiple and credible options wih regard to electricity demand/ supply scenario in the country, are also leading to a scenario wherein the unacceptably costly options such as massive size coal, nuclear and hydro power projects are being pursued without any rational discussions, even as late as 2024. 
Sadly, even the media discussions on such issues can also be seen as endorsing such irrational policies without objective deliberations.
A discussion paper sent to CEA in the form of invited public comments on its draft National Electricity Plan Volume II, Transmission (years 2022-27) has highlighted many of the associated issues of importance.
Whereas, it is deplorable that such credible feedback from civil society groups/ individuals are rarely, if ever, acknowledged by our officials (let alone commenting on them), I hope they are, at least, acted on.
So much for the oft repeated slogan: "sub ke saath, sub ka vikaas, sub ka vishwaas".

Walk for peace: Buddhist monks and America’s search for healing

By Vidya Bhushan Rawat*  The #BuddhistMonks in the United States have completed their #WalkForPeace after covering nearly 3,700 kilometers in an arduous journey. They reached Washington, DC yesterday. The journey began at the Huong Đạo Vipassana Bhavana Center in Fort Worth, Texas, on October 26, 2025, and concluded in Washington, DC after a 108-day walk. The monks, mainly from Vietnam and Thailand, undertook this journey for peace and mindfulness. Their number ranged between 19 and 24. Led by Venerable Bhikkhu Pannakara (also known as Sư Tuệ Nhân), a Vietnamese-born monk based in the United States, this “Walk for Peace” reflected deeply on the crisis within American society and the search for inner strength among its people.

Pace bowlers who transcended pace bowling prowess to heights unscaled

By Harsh Thakor*   This is my selection and ranking of the most complete and versatile fast bowlers of all time. They are not rated on the basis of statistics or sheer speed, but on all-round pace-bowling skill. I have given preference to technical mastery over raw talent, and versatility over raw pace.

When a lake becomes real estate: The mismanagement of Hyderabad’s waterbodies

By Dr Mansee Bal Bhargava*  Misunderstood, misinterpreted and misguided governance and management of urban lakes in India —illustrated here through Hyderabad —demands urgent attention from Urban Local Bodies (ULBs), the political establishment, the judiciary, the builder–developer lobby, and most importantly, the citizens of Hyderabad. Fundamental misconceptions about urban lakes have shaped policies and practices that systematically misuse, abuse and ultimately erase them—often in the name of urban development.

Bangladesh goes to polls as press freedom concerns surface

By Nava Thakuria*  As Bangladesh heads for its 13th Parliamentary election and a referendum on the July National Charter simultaneously on Thursday (12 February 2026), interim government chief Professor Muhammad Yunus has urged all participating candidates to rise above personal and party interests and prioritize the greater interests of the Muslim-majority nation, regardless of the poll outcomes. 

When grief becomes grace: Kerala's quiet revolution in organ donation

By Vidya Bhushan Rawat*  Kerala is an important model for understanding India's diversity precisely because the religious and cultural plurality it has witnessed over centuries brought together traditions and good practices from across the world. Kerala had India's first communist government, was the first state where a duly elected government was dismissed, and remains the first state to achieve near-total literacy. It is also a land where Christianity and Islam took root before they spread to Europe and other parts of the world. Kerala has deep historic rationalist and secular traditions.

Beyond the conflict: Experts outline roadmap for humane street dog solutions

By A Representative   In a direct response to the rising polarization surrounding India’s street dog population, a high-level coalition of parliamentarians, legal experts, and civil society leaders gathered in the capital to propose a unified national framework for humane animal management. The emergency deliberations were sparked by a recent Suo Moto judgment that has significantly deepened the divide between animal welfare advocates and those calling for the removal of community dogs, a tension that has recently escalated into reported violence against both animals and their caretakers in states like Telangana.
