Kosol Energie Targets Storage, Agriculture Solar as Next Growth Engines

India’s renewable energy company Kosol Energie is preparing for expansion in battery energy storage and agricultural solar solutions, supported by a strong order pipeline and new technology partnerships, Executive Director Kayan Kalthia said in an exclusive interview with Saur Energy at the sidelines of Inter Solar, Gandhinagar. 

Kalthia said the company has spent nearly 15 years building its presence in the solar PV sector with a focus on quality and reliability despite intense price competition.

The company initially took on projects with strict energy generation guarantees to demonstrate confidence in its products and build credibility in the market, he said.

Rooftop Solar Projects

Kosol was part of one of India’s earliest rooftop solar tenders — a 2.5-MW project executed with SunEdison around 2013–14.

More recently, the company received a letter of intent for 300 MW of rooftop installations under a broader 1.1-GW rooftop programme, making it the largest order winner in that initiative, Kalthia said.

He said the order reflects the company’s growing execution capability after years of operating in the sector.

Entry Into Battery Storage

Kosol is now expanding into battery energy storage systems (BESS), which Kalthia expects to grow rapidly in India as renewable capacity increases. The company has entered a technical partnership with U.S.-based Gridscale to bring battery software and system expertise to India.

Kosol, the leadership said is focusing on increasing domestic value addition, particularly in software components such as battery management systems (BMS) and energy management systems (EMS), which control the performance and safety of storage systems.

Agricultural Solar Expansion

Kosol has installed more than 10,000 solar pumps across seven Indian states and over 200 districts, and contributed to Maharashtra setting a Guinness World Record for the highest number of solar pumps installed. The company’s agriculture-focused brand Koraam is currently its most profitable vertical, developing solar-based solutions such as cold storage aimed at increasing farmers’ income.

Kosol operates multiple renewable energy verticals, which Kalthia said helps reduce business risk and opens several revenue streams. The company currently has an order book of more than ₹4,000 crore, spread across its different business segments.

Kalthia said India’s battery storage market could see a surge of new entrants similar to the early growth of solar manufacturing. However, he expects consolidation over time as quality and reliability become decisive factors in the sector.

Policy and Skills

He said government support should increasingly focus on research and development and skill development in addition to financial incentives. India has strong potential in battery-related research, particularly due to its chemical industry capabilities, he added. Kosol is also working to address the shortage of skilled workers in the fast-growing storage sector through internal training and partnerships.

AI-Based Microgrid Planning

Among its new offerings, the company has launched an AI-driven microgrid software platform that helps businesses and developers determine the optimal size of battery storage systems and estimate returns on investment. The system analyses energy usage patterns and existing power sources to recommend efficient storage deployment, Kalthia said.
