KSEB EV Charging Tariff 2026 — Complete Rate Chart

"How much does it cost to charge an EV on KSEB electricity?" — Understanding KSEB's tariff structure is essential for anyone planning to charge at home or set up a commercial station in Kerala. Here's the complete 2026 rate chart.

Dedicated EV Charging Tariff

KSEB offers a dedicated EV charging tariff of approximately ₹6–6.50 per kWh for connections with a separate EV meter. This is significantly lower than the standard commercial tariff of ₹8–10 per kWh, making dedicated EV connections the most economical option.

Domestic Tariff Slabs for Home Charging

Most home users charge on their existing domestic connection. KSEB's domestic tariff is slab-based (FY 2025–26): 0–40 units at ₹2.90/kWh, 41–80 at ₹3.50, 81–140 at ₹4.90, 141–180 at ₹6.90, 181–250 at ₹7.45, and 251+ at ₹8.00. A typical EV adds 200–300 units/month to your bill.

Why a Separate EV Meter Saves Money

The most cost-effective approach for heavy EV users is to apply for a separate KSEB meter dedicated to EV charging. This avoids pushing your domestic consumption into higher slabs. See our guide on common installation mistakes that include ignoring meter separation.

Commercial Station Margins

For commercial charging stations, commercial connections offer competitive electricity rates. Margins depend on your KSEB tariff category, charger type, and time-of-day pricing. Contact us for a detailed margin analysis based on your location.

Time-of-Day Tariffs Coming

KSEB has implemented time-of-day pricing at its public stations since May 2025. Daytime (9 AM–4 PM) charging is ~30% cheaper than nighttime (4 PM–9 AM), incentivizing solar-hour charging. For fleet depot charging, scheduling during daytime hours delivers the best economics.
