How Sikkim (Sikkim Power Development Corporation (SPDC) / EPDS) Bills You

Understanding slabs, billing cycles, subsidies, and non-tariff exclusions

Electricity in Sikkim is distributed and billed by Sikkim Power Development Corporation (SPDC) / EPDS under regulatory tariff schedules set by the State Electricity Regulatory Commission. Domestic residential consumers fall under the subsidized LT-1 tariff category, which uses a telescopic slab structure.

Under this system, the billing cycle is monthly. Telescopic billing ensures that your total consumption is split across successive brackets: lower units are billed at foundational rates starting at ₹2.25/unit, while higher rates apply only to additional units in subsequent tiers.

Domestic consumers may also benefit from state government subsidy allowances or free unit tiers where enacted.
