TPDDL Solar Net Metering — Export Rate

Under net metering, TPDDL consumers with rooftop solar systems can export surplus electricity to the grid and receive credit. DERC's FY2026 tariff order sets the solar export tariff at ₹3.00/unit uniformly for BRPL, BYPL and TPDDL. Note Delhi also levies a Power Purchase Adjustment Charge (PPAC) on top of base tariffs, revised monthly — around 16% for TPDDL as of mid-2026 — which affects your effective per-unit cost.

Net metering settlement for TPDDL is as per DERC net metering regulations, as per DERC (Delhi Electricity Regulatory Commission) regulations.

How Solar Saves Money Under TPDDL Tariffs

For a household consuming 300–400 units per month in the TPDDL area, a 3 kW solar system can offset 300–360 units per month (25 kWh/day average). At current TPDDL 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.
