Opten Power is India's unified clean energy marketplace, purpose-built to help commercial and industrial businesses discover, transact, and accelerate their renewable energy journey. From Chennai's booming IT parks to Coimbatore's manufacturing clusters, Tamil Nadu businesses face rising grid tariffs of ₹10–15 per unit — a challenge Opten Power directly addresses through intelligent PPA structuring. By bringing together C&I buyers, top renewable developers, financiers, and EPC companies on a single platform, Opten Power eliminates inefficiency from energy procurement. With 4+ GW of pre-vetted capacity, presence across 16 states, and an automated deal engine, the platform empowers businesses to cut energy costs by up to 40% and close deals 50% faster — with complete transparency at every step.
A Power Purchase Agreement (PPA) is a long-term contract between an energy buyer and a renewable energy developer. The developer installs and operates a solar, wind, or hybrid plant, and you purchase the electricity generated at a pre-agreed per-unit tariff — typically lower than grid rates. In Tamil Nadu, PPAs are commonly structured under Third-Party Open Access or Group-Captive models to maximize savings.
