Frequently Asked Questions
What are the domestic electricity tariff slabs in Sikkim?
Under Domestic, telescopic billing applies across 3 slabs, from ₹2.5/unit for the first 100 units up to ₹4.1/unit for the highest slab.
What is the electricity duty in Sikkim?
For Domestic in Sikkim, electricity duty is charged at 4% of the energy charge. Other connection categories in the state can have a different duty rate — switch categories in the calculator above to see each one.
What is the difference between telescopic and non-telescopic electricity billing?
In telescopic (slab-wise progressive) billing, each unit is charged at the rate of the slab it falls into, so only the portion above a threshold is billed at the higher rate. In non-telescopic billing, crossing into a higher slab means the entire month's consumption is billed at that slab's rate, not just the excess.
