Chinese energy storage maker Sigenergy plans to invest an initial $250 million in India to build factories for inverters and battery energy storage systems (BESS), according to a Reuters report published on Oct. 23.
Sigenergy's inverter plant is targeted for Q2 2027, with the BESS factory 6-8 months later, according to Reuters; the site is not named.

Rahul Morde, head of sales for Sigenergy India, told Reuters the company will build the inverter plant first and expects it to be operational by the second quarter of 2027. The company is still exploring possible locations for the factory, and no site has been named.
A BESS factory is to follow, coming online six to eight months after the inverter facility, Morde said on the sidelines of the Renewable Energy India Expo. Sigenergy also plans a research and development centre in India focused on battery energy storage systems.
India is looking to expand renewable capacity and grid-scale storage quickly, which Reuters describes as creating opportunities for manufacturers. A local inverter and BESS line would let Sigenergy supply storage projects from inside the country rather than by import. Sigenergy has not given output figures, so the plants' capacity in GWh per year is unknown, and the report does not say which cell chemistry or which cell supplier the systems would use.
The timeline is the practical signal: an inverter plant targeted for the second quarter of 2027, with the BESS factory six to eight months behind it. That is a company schedule, not a commitment backed by approvals.
Sigenergy develops and manufactures energy storage systems, including battery products, inverters and energy management software for residential and commercial customers, according to Reuters. The company listed in Hong Kong in April, raising HK$4.4 billion ($562 million) in its initial public offering.
Morde said Sigenergy has complied with India's rules on storing data in the country and is seeking investment clearances. Those clearances are the main unconfirmed step. For Chinese-owned manufacturers, approval timing can decide whether the stated schedule is met, but the report does not say what approvals are pending beyond that.
The factory location, output capacity, staffing and the split of the $250 million between the inverter and BESS plants have not been disclosed. The $250 million is described as an initial figure, so the total could be higher. Voltgrid will update when Sigenergy names a site or files for approvals.
