Who each rate applies to
Domestic — single phase
Five telescopic slabs from ₹1.60 to ₹4.60, with no fixed charge. A monthly minimum of ₹50 applies, so bills below that are rounded up to it.
Domestic — three phase
The same energy rates, but the monthly minimum rises to ₹200.
ℹ️ Sikkim has some of the cheapest electricity in India — ₹1.60 for the first 50 units, on the back of the state's hydro generation — and levies no fixed charge at all. The ₹50 (single phase) or ₹200 (three phase) in the schedule is a monthly MINIMUM, not a standing charge: it only bites if your energy charges come to less than that, so a household using 100 units pays ₹210 in energy and nothing more. The Department allows a 5% rebate on energy charges for bills paid within the due date (10 days from issue), and charges a 10% annual surcharge on arrears outstanding at the end of March. Neither is applied automatically here. If electricity supplied to domestic premises is used for a commercial purpose, the Department charges the ENTIRE supply at commercial rates.

ℹ️ Commercial supply runs from ₹4.10 to ₹7.40 across the same five slab boundaries as domestic, and likewise carries no fixed charge. Establishments with a sanctioned load above 25 kVA that run off a shared transformer pay a demand charge on top — ₹60/kVA/month in rural areas, ₹100/kVA/month in urban — which is not modelled here. A connection of 100 kVA or above must install its own transformer. The Department allows a 5% rebate on energy charges for bills paid within the due date (10 days from issue), and charges a 10% annual surcharge on arrears outstanding at the end of March. Neither is applied automatically here.
