new delhi, Jan. 14 -- The Centre is considering a proposal to require wind and solar farms supplying power to the grid, along with standalone energy storage systems, to install battery storage systems featuring a minimum level of domestic components, three people familiar with the discussions said.

The government is looking to mandate at least 50% local content for components including battery and energy management systems, containers, and inverters used in Battery Energy Storage Systems (BESS), but excluding cells, the people cited above said on the condition of anonymity. Authorities may also introduce a list of approved manufacturers and models, mirroring a policy already in place for the solar industry known as the Approved List of Models and Manufacturers. The power ministry held a consultation last week with executives from state-run firms including NTPC Ltd and Solar Energy Corp. of India Ltd (Seci), as well as private players such as JSW Energy Ltd, Engie SA, and Avaada Electro. The consultations sought views on a transition timeline for indigenization, one of the people said. "The government wants to understand whether the industry is prepared to cater to the growing demand and by what time the mandates can be implemented," the person said. "The eventual target is to indigenize the supply chain and reduce the foreign exchange outflow associated with the green energy shift." Spokespersons of power ministry, NTPC, SECI, JSW Energy, Avaada Electro, and Engie did not respond to emailed queries.htc...
