The Opportunity

Why the Nilgiris Cascade Is Underperforming

Despite 840 MW of installed capacity, the cascade operates as isolated independent stations with no system-wide optimisation — leaving hundreds of GWh of clean energy unrealised every year.

🔌

Fragmented Operation

Kundah, Pykara and Moyar operate independently. No shared optimisation platform exists to coordinate transmission, generation and reservoir operations simultaneously.

💧

Reservoir Inefficiency

Reservoir management relies on localised forecasting. Water spills in wet seasons, is under-utilised in dry periods. Coordinated scheduling recovers significant additional energy from the same water.

⚡

Transmission Losses

Each station evacuates power separately with higher losses. A shared 400 kV collector backbone plus modern low-loss transformers delivers immediate efficiency gains of 1–6%.
