Renewable Energy Models
Explained Visually
Step-by-step animated guide to all major renewable energy models — Group Captive, BESS, Capex, Rooftop Solar, and OPEX/PPA — and how they work for Kerala industries.
Parent Co. & Its Plants Face High Grid Bills
A parent company with multiple industrial plants in Kerala pays ₹9–12/unit to KSEB. Electricity is their biggest cost.
The 4-Step Process
Equity Investment
Industries collectively invest in a renewable energy generating company. Each member holds ≥26% equity stake.
Plant Generation
A wind or solar plant (typically in TN/KA) generates electricity around the clock under a long-term PPA structure.
Grid Wheeling
Power is delivered to Kerala using the existing transmission infrastructure. A small wheeling charge is paid for grid usage.
30–40% Savings
Industries receive power at ₹4.5–6.5/unit instead of paying ₹9–12/unit to KSEB — a permanent structural cost reduction.
Common Questions
What is the minimum equity required?
Each industry must hold at least 26% equity in the generating company and consume at least 51% of the plant's output annually.
Does the plant need to be in Kerala?
No. Industries can hold equity in a wind or solar project in Tamil Nadu or Karnataka and receive power via inter-state open access.
How much can an industry save?
Most industries save 30–40% on electricity costs — effective tariff drops from ₹9–12/unit (KSEB) to ₹4.5–6.5/unit.
What types of industries can participate?
Any industry with 1 MW+ demand — manufacturing, hospitals, hotels, IT campuses, and commercial buildings.
