CESC Solar Net Metering — Export Rate

Under net metering, CESC consumers with rooftop solar systems can export surplus electricity to the grid and receive credit. CESC's net metering allows up to 500kW per consumer connection with a bi-directional smart meter (provided and installed by CESC), monthly billing with excess export credited against consumption, and any remaining credit carried forward. CESC has not published one single confirmed feed-in export rate as consistently as some other DISCOMs — verify the current applicable rate directly at cesc.co.in/tariff or with your CESC office before finalising your solar investment calculations.

Net metering settlement for CESC is monthly, with carry-forward of remaining credit, as per WBERC (West Bengal Electricity Regulatory Commission) regulations.

How Solar Saves Money Under CESC Tariffs

For a household consuming 300–400 units per month in the CESC area, a 3 kW solar system can offset 300–360 units per month (25 kWh/day average). At current CESC tariffs, this can save a meaningful portion of the electricity bill each month, depending on which consumption slab your usage falls into and your generation profile.
