Formerly known as SolarGridX, SustVest combines fintech innovation with renewable energy financing to make impact investing more accessible and scalable.

The platform’s core business model revolves around offering fractional investments in renewable energy assets, primarily solar power installations, through securitized debt instruments. Investors can begin with amounts as low as ₹5,000, allowing individuals to earn returns generated from energy income produced by operational projects. These investments target annualized returns while supporting the growth of sustainable infrastructure.

For commercial and industrial clients, MSMEs, and government organizations, SustVest facilitates the adoption of solar energy without requiring upfront capital expenditure. Through structured power purchase agreements (PPAs), businesses and institutions pay only for the electricity consumed, enabling them to transition to clean energy while significantly reducing electricity costs. This financing model simultaneously creates recurring revenue streams for investors participating in the platform.

SustVest provides a digital investment interface where users can manage portfolios, review project due diligence reports, monitor asset performance, and track investment returns. The company has financed renewable energy projects for organizations including Lodha Group, Hitachi, as well as government agencies such as Central Industrial Security Force and Central Reserve Police Force.

As of late 2024, SustVest reported more than ₹43 crore in assets under management (AUM) and approximately 9.3 MW of financed solar installations. Looking ahead, the company plans to expand into additional sustainable infrastructure categories, including EV charging networks, small hydro projects, and wind energy assets, further broadening its clean energy investment ecosystem.
