CESC Limited (CESC.NS): How It Makes Money

• Consumer base: ~4.7 million electricity consumers across seven locations including Kolkata, Howrah, Greater Noida and Chandigarh - a stable retail revenue foundation.
• Generation portfolio: Thermal and renewable plants sell power via captive supply, merchant sales and PPAs; margin driven by fuel mix and plant efficiency.
• Distribution operations: Regulated tariffs and collection efficiency in urban franchises provide predictable cash flows and opportunities from distribution privatization reforms.
• Renewable energy sales & REC/merchant markets: Rapid buildout of contracted and merchant renewables adds high-growth, low-marginal-cost revenue.
• New businesses: Solar cell/module manufacturing, EV charging infrastructure, smart-grid services and O&M/consulting create diversified revenue streams and higher-margin services.

• Regulated retail tariffs: Fixed and variable charges collected from urban distribution franchises provide base revenue and predictable billing cycles.
• Power generation sales: Merchant and PPA-backed sales from thermal and renewable plants - margins affected by fuel cost, carbon regulations and renewable curtailment.
• Renewable asset sales/PPAs: Long-term PPAs and merchant sale of green power; eligibility for carbon credits/RECs improves realized prices.
