The Solar Company That Ate a Battery Business (And Wants More)

When Your Solar Company Decides to Become a Battery Company Too

Let’s talk about KPI Green Energy. Yes, the renewable energy company. No, not the one with the tiger mascot. Yes, the one where the promoter is aggressively buying his own company back because (and this is a direct quote from concall transcripts) he needs to “hit 12% IRRs and monetize offshore projects.” Translation: global expansion mode activated, and we need fresh equity capital.

KPI was incorporated in 2008 and has been quietly building renewable power plants—mostly solar, some hybrid—across Gujarat under two business models: one where they build and own power plants (IPP), and another where they build them for companies who want their own captive power (CPP/EPC). Think of it as the difference between owning a coffee shop vs. being hired to build coffee shops for Starbucks.

Until 2024, the company lived a boring life: ₹350 crore revenue in FY25, margins of 30–35% EBITDA, minimal debt, and a founder who went to concalls like they were his own Twitter feed. Then something snapped. Suddenly there are 2.17 GW of IPP projects under development, a ₹3,200 crore SBI credit line, a ₹670 crore green bond, and a subsidiary (Sun Drops Energy) being spun into an IPO to fund a ₹445 MW battery storage business with the Gujarat government. The boring renewable company just became a capex-heavy growth machine.

Q3 FY26 reported ₹676 crore revenue, 45% YoY growth, highest-ever quarterly numbers, and—oh yes—the concall disclosed that Khavda (the 240 MW solar project) finally started feeding power to the grid in January 2026 after sitting idle for four months waiting for a government substation. Welcome to renewable energy infrastructure in India: spectacular execution timelines, occasional “government delays.”

The Company’s Three-Legged Stool (And It’s Getting Wobbly)

KPI operates through three main revenue streams, and understanding them separately is critical because they don’t behave the same way.

Leg 1: Captive Power Producer (CPP) / EPC Services (88% of Q3 revenue): Companies want cheaper electricity than the DISCOM. KPI designs, builds, and maintains solar power plants on their premises under turnkey contracts. Think of it as solar installation consultancy for corporate India. Margins: 18–20% EBITDA. Order book: ₹5,500+ crore. Execution timeline: 6–8 months for smaller projects. Revenue is lumpy based on project completion, not progress.

Leg 2: Independent Power Producer (IPP) (12% of current revenue, expanding to 25–30% by FY30): KPI builds solar/hybrid power plants and owns them, selling power to GUVNL or private offtakers under long-term contracts (20–25 years). Margins: 85–90% EBITDA (because once the plant is built, there are no goods costs). This is the annuity play. Problem: capex-heavy upfront (₹1,500–1,700 crore for 500 MW), and cash flows kick in only after COD and ramp-up. Khavda was supposed to contribute from Q3; instead, it just started sending photons to the grid in January. Welcome to “inflation + supply chain + government infrastructure delays.”

Leg 3: Battery Energy Storage Systems (BESS) (New, ~0% revenue today, ₹445 MW LOI from GUVNL): GUVNL just handed KPI a letter of intent to develop 445 MW / 890 MWh standalone battery storage. Capex: ₹1,000–1,100 crore. Expected IRR: 13–14% (lower than IPP due to falling battery costs). Subsidiary: Sun Drops Energy, being IPO’d in H1 FY27 to fund this. Management retention: KPI will hold 51%+ post-IPO, meaning consolidation continues.
