Sun Drops Energia Limited, an unlisted renewable energy company currently trading at around ₹295 per share, has rapidly emerged as one of the promising players in India’s clean energy transition. As the country accelerates investments in renewable energy, battery storage, and round-the-clock green power, the company is strategically positioning itself to capitalize on these long-term growth opportunities.
Incorporated on 28 May 2019 and headquartered in Surat, Gujarat, Sun Drops Energia is a key subsidiary of KPI Green Energy Limited. The company has built a strong presence in captive solar, hybrid renewable energy, and Independent Power Producer (IPP) projects, delivering impressive financial growth over the past few years. It is now expanding into Battery Energy Storage Systems (BESS)—a fast-growing segment expected to play a critical role in enabling India’s renewable energy ambitions.
With India targeting 500 GW of non-fossil fuel capacity by 2030 and requiring 47 GW / 236 GWh of battery storage by FY2032, BESS is expected to become one of the country’s largest infrastructure opportunities. Through its recent utility-scale BESS projects, Sun Drops Energia is aiming to diversify beyond traditional renewable power generation and participate in the next phase of India’s energy transition.
What Does Sun Drops Energia Do?
Sun Drops Energia operates through three key business verticals that provide both project-based and recurring revenue, positioning the company to benefit from India’s growing renewable energy market.
1. Captive Power Producer (CPP)
The company develops solar and wind-solar hybrid power projects for commercial and industrial (C&I) customers such as textile, chemical, pharmaceutical, engineering companies, and data centres. These businesses adopt captive renewable energy to reduce electricity costs and meet sustainability goals.Sun Drops primarily executes projects of up to 35 MW, while also undertaking turnkey solar EPC and Balance of System (BoS) contracts, generating steady project execution revenue.
2. Independent Power Producer (IPP)
Under the IPP model, Sun Drops owns renewable power plants and sells electricity through long-term Power Purchase Agreements (PPAs), creating predictable recurring revenue.As of FY26, the company operates around 22 MW of installed IPP capacity, complementing its EPC business with long-term cash flows.
3. Battery Energy Storage System (BESS)
BESS is Sun Drops Energia’s newest and potentially most significant growth opportunity. Unlike solar plants, batteries do not generate electricity—they store excess renewable power during the day and supply it back to the grid during peak demand, improving grid reliability and enabling round-the-clock clean energy.
Sun Drops has been designated as the primary BESS platform for KPI Green Energy and has already secured 565 MW / 1,130 MWh of utility-scale BESS projects from GUVNL. As India targets 47 GW / 236 GWh of battery storage by FY2032, BESS could become a key long-term growth driver for the company.
How Has Sun Drops Energia Performed So Far?
Over the last five years, Sun Drops Energia has transformed from a relatively small renewable energy developer into one of the fastest-growing companies in India’s renewable energy sector. Backed by strong execution capabilities and increasing demand for captive renewable energy projects, the company has delivered exceptional financial growth.
Revenue increased from ₹4.79 crore in FY22 to ₹586 crore in FY26, reflecting rapid business expansion driven by higher project execution, capacity additions, and growing adoption of renewable energy by commercial and industrial (C&I) customers.
The company’s profitability has improved alongside its revenue growth. Profit Before Tax (PBT) rose from ₹1.17 crore in FY22 to ₹130 crore in FY26, while Profit After Tax (PAT) increased from ₹0.88 crore to ₹97 crore during the same period.
Looking ahead, management remains optimistic about the company’s growth prospects. For FY27, the company has guided for 50–60% revenue growth while maintaining an EBITDA margin of 25–30%, indicating confidence in both project execution and profitability.
As of Q3 FY26, Sun Drops Energia reported an order book of approximately ₹500 crore, consisting primarily of captive solar and wind-solar hybrid projects for commercial and industrial customers. This provides healthy revenue visibility over the near term and supports management’s growth guidance.
Why Could BESS Be Sun Drops Energia’s Next Growth Engine?
While Sun Drops Energia has built a strong business around solar and hybrid renewable energy projects, its next phase of growth could be driven by Battery Energy Storage Systems (BESS). India’s installed power generation capacity has already crossed 520 GW, comprising around 248 GW of fossil fuel capacity and 272 GW of non-fossil capacity. Within the renewable segment, solar alone accounts for approximately 162 GW, making it the largest source of clean energy in the country. The pace of expansion is accelerating rapidly, with India adding around 52 GW of new power capacity in the last year alone, of which nearly 35 GW came from solar. This highlights that future investments in India’s power sector will continue to be dominated by renewable energy.
Looking ahead, the Government of India aims to increase solar capacity to 280–300 GW by 2030 while expanding the country’s total installed power generation capacity to around 874 GW. However, adding more solar capacity alone is not enough. As renewable energy penetration increases, the need for energy storage becomes equally important to ensure reliable round-the-clock electricity supply. This is where Battery Energy Storage Systems (BESS) become critical, creating a massive long-term opportunity for companies like Sun Drops Energia that are expanding beyond renewable power generation into utility-scale energy storage.
The Renewable Energy Challenge
Despite non-fossil sources accounting for more than 50% of India’s installed power capacity, they contribute only around 30% of actual electricity generation, while thermal power continues to generate nearly 70% of the country’s electricity. The reason is simple—solar power is produced only during daylight hours, whereas electricity demand remains high during the evening and night. As a result, coal-fired power plants continue to operate after sunset to ensure uninterrupted power supply, limiting the overall contribution of renewable energy to India’s electricity generation.
This challenge creates a significant opportunity for Battery Energy Storage Systems (BESS). Instead of letting surplus solar power go unused during the day, BESS stores the excess electricity and supplies it back to the grid during peak demand hours. By enabling renewable energy to be available even after sunset, battery storage improves grid stability, reduces dependence on thermal power, and plays a crucial role in India’s transition towards reliable, round-the-clock clean energy. This structural shift is also why companies like Sun Drops Energia are expanding aggressively into the utility-scale BESS market.
How Does Sun Drops Energia Benefit from BESS?
Recognising the long-term opportunity in energy storage, Sun Drops Energia has entered the utility-scale Battery Energy Storage System (BESS) business, which is expected to become a key growth driver over the coming years. Unlike battery manufacturers, the company does not produce battery cells. Instead, it procures battery systems from leading suppliers, develops the storage infrastructure, owns and operates the assets, and earns long-term contracted revenue by providing battery storage services under Battery Energy Storage Purchase Agreements (BESPAs).
Sun Drops has already secured 565 MW / 1,130 MWh of standalone BESS projects from GUVNL, marking its entry into one of India’s fastest-growing energy infrastructure segments. The company plans to invest around ₹1,100 crore in these projects, with management guiding for a project IRR of 14–15%. As India’s battery storage market expands, these long-term contracted projects could diversify Sun Drops Energia’s revenue base and strengthen its position in the country’s renewable energy ecosystem.
A Massive Market Opportunity
India’s Battery Energy Storage System (BESS) market is still at a very early stage, with less than 1 GW of operational utility-scale battery storage capacity. However, as renewable energy capacity continues to expand, the need for energy storage is expected to rise sharply. According to the Central Electricity Authority (CEA), India will require around 47 GW / 236 GWh of BESS capacity by FY2032, creating an investment opportunity of nearly ₹4.8 lakh crore, including ₹3.5 lakh crore in BESS and ₹1.3 lakh crore in pumped storage projects.
The project pipeline already highlights the scale of this opportunity. Around 16 GW of BESS capacity is currently under construction, 12 GW has already been awarded, and another 19 GW is in the tendering stage. This indicates that India’s battery storage industry is entering a multi-year growth cycle, creating significant opportunities for developers like Sun Drops Energia that have already secured large utility-scale BESS projects and possess the execution capabilities to participate in this rapidly expanding market.
Conclusion
Sun Drops Energia has rapidly evolved from a captive renewable energy developer into a diversified clean energy company with businesses spanning solar EPC, captive power, Independent Power Production (IPP), and Battery Energy Storage Systems (BESS). While its solar business continues to drive growth, the company’s entry into utility-scale BESS comes at a time when India is entering a multi-year battery storage expansion cycle.
Although Sun Drops’ current 565 MW / 1,130 MWh BESS portfolio represents only a small portion of India’s projected 47 GW storage requirement by FY2032, it provides the company with an early foothold in a high-growth market. Going forward, the successful execution of these projects, additional BESS order wins, and sustained growth in its core renewable energy business will be key factors determining whether Sun Drops Energia can emerge as a significant player in India’s evolving clean energy ecosystem.
