Sun Drops Energia ₹4,000-Crore IPO Plan & Battery Expansion

KP Group is reportedly planning a ₹4,000-crore initial public offering (IPO) of Sun Drops Energia Limited within 10–12 months of the October 2026 report. Preparations for its draft red herring prospectus (DRHP), the document describing a proposed public offer, are said to be in their final stages.

The proposed listing comes alongside an expansion into battery storage and manufacturing. Sun Drops is a subsidiary of KPI Green Energy, within KP Group.

What is known about the IPO plan?

The ₹4,000-crore figure is the reported offer amount, rather than an established company valuation. The split between newly issued shares and an offer for sale by existing shareholders has not been established, so the amount of cash that would reach the company is also unclear.

For current holders, issuing new shares can dilute percentage ownership, while an offer for sale involves existing shareholders selling their shares. Any company-specific effect depends on the eventual offer structure.

The 10–12-month timeframe is a reported target, not a confirmed listing date. As of 5 October 2026, a completed DRHP filing, price band and issue dates had not been independently verified in the sources reviewed.

Management had discussed Sun Drops’ proposed listing in August 2025. The current development is the reported offer size and timetable.

How battery storage fits the business

Under KP Group’s business framework presented on 30 September 2026, Sun Drops is assigned battery energy storage system (BESS) projects, battery manufacturing, group-captive renewable projects and solar/hybrid engineering, procurement and construction (EPC) contracts up to 50 MW. Its storage remit includes building projects for customers and developing projects to own and operate.

BESS stores electricity for delivery later. The manufacturing roadmap targets a BESS assembly line capable of producing 5 GWh annually in FY2027–28, followed by 5 GWh of annual cell-production capacity in FY2028–29. Both lines are intended to expand to 10 GWh each over the longer term at an approximately 110-acre Gujarat campus. These remain planned annual manufacturing capacities.

Sun Drops also executed a battery energy storage purchase agreement with Gujarat Urja Vikas Nigam Limited (GUVNL), disclosed on 19 May 2026, for a 120 MW/240 MWh project. The agreement establishes contracted project scope, rather than commissioning. Project storage capacity and annual manufacturing capacity measure different activities and should not be added together.

What investors should watch next

A verified offer document would clarify the issue structure and proposed use of proceeds. The reported IPO amount alone does not establish an allocation to the battery expansion. Subsequent offer disclosures would also be needed to establish pricing and application dates.
