CESC Business Segments And Revenue Model

For CESC Limited, electricity supply to Kolkata, Howrah, and surrounding areas continues to account for most of the business. Its consumer base includes households, industries, and commercial establishments within the licensed distribution area. Power is drawn from owned thermal stations such as Budge Budge Generating Station and Southern Generating Station, along with supply from Haldia Thermal Power Station and purchased electricity.

Transmission and distribution form another important part of operations through a wide network built across multiple voltage levels. A smaller part of its portfolio comes from solar plants in Gujarat and Tamil Nadu, with captive coal meeting part of its fuel requirement.
