NEW DELHI – The government expects renewables to become a critical component of India's energy security in future, Secretary in the Ministry of New and Renewable Energy Santosh Kumar Sarangi said Friday. Referring to the success of the solar rooftop project, he said, "I foresee an exponential growth in distributed renewable energy in the Indian context."

 

He said in order to become self-sufficient in the renewable energy sector, India needs to ramp up manufacturing in the entire value chain of solar, wind energy and hydrogen mission. "In the solar value chain, I think we would have polysilicon, which is the upstream component of solar, up and running in our country by about 2029-30. On ingot wafer, a lot of them have made investment decision, and we expect by June of 2028, about 30 to 50 gigawatt of capacity coming in. On the hydrogen segment, we have electrolyzer manufacturing, which has already been initiated. The upstream of that in terms of membranes and separators, we would expect that by 2030-31, a lot of manufacturing capability comes in," Sarangi said at Bloomberg New Energy Finance Summit 2026.

 

There are excellent investment opportunities in deployment, manufacturing and energy storage. "Whether it is pump storage projects, whether it is the lithium ion batteries, whether it is sodium ion and vanadium flow batteries. I think the investment opportunities are excellent in the country," he said.

 

Sarangi said there is scope for "gigantic growth in battery energy storage system installation in the country." Some Indian companies have started looking beyond lithium-ion batteries and have already started investing in sodium-ion batteries and vanadium flow battery projects.  

 

 

 

Sarangi expects the cost of flow batteries to be fairly competitive with lithium ion batteries in the next 2 to 3 years. "There are manufacturers within the country who are doing manufacturing of flow batteries and I foresee that the cost will be fairly competitive with lithium ion batteries in the next 2 to 3 years and that trajectory will allow a lot of these renewable projects to leverage battery energy storage systems to supply firm and reliable power," the secretary said.

 

Sarangi said there is scope for "gigantic growth in battery energy storage system installation in the country. Some Indian companies have started looking beyond lithium-ion batteries and have already started investing in sodium-ion batteries and vanadium flow battery projects. As per Sarangi, the ministry is also coming up with the successor scheme of PM Kusum which will also have battery energy storage component and that would allow better management of decentralized renewable energy generation. "We are also looking at adding a polysilicon component through which we will provide capital expenditure to polysilicon manufacturers and encourage them to come up with polysilicon," the secretary said, adding that pump storage projects will also get a hiuge thurst from industry stakeholders. 

 

On a question related to auctions, the tariff-based competitive bidding has served the renewable industry well, according to Sarangi. The renewable energy will support India's growth sectors, Sarangi said. 

 

The renewable energy would require about INR 13 billion dollars of investment by 2070 and around INR 300 billion by 2030, as per Sarangi.  End
