Bihar bijli bill: check it, understand it, pay it on Subspace

The company name is at the top of your bill. Both use a CA number as the account ID, and both websites have the same tools: View & Pay Bill for a bijli bill check, Print Receipt for payment proof, and links to the Bihar Bijli Smart Meter app for prepaid meters. Use nbpdcl.co.in or sbpdcl.co.in to match your bill. Both companies share the toll-free numbers 1912 and 1800-202-2813. Detailed guides: NBPDCL bill payment and SBPDCL bill payment.

Under the state's Mukhyamantri Vidyut Upbhokta Sahayata Yojana, from July 2025 consumption every domestic consumer gets the first 125 units a month free. That covers the energy charge, the fixed charge and electricity duty on those units. A few rules decide what you see on the bill:

• Up to 125 units: nothing to pay for energy, fixed charge or duty.
• Above 125 units: only the extra units are charged, at the subsidised rate for your category, plus duty. The fixed charge applies for the full period, on the higher of your recorded load or 75% of sanctioned load.
• Billing periods other than 30 days: the free allowance is pro-rated as 125 × days ÷ 30.

In 2026-27, BERC also merged the urban slabs into a single ₹7.42 rate, cutting the price of the old upper slab by ₹1.53 a unit before subsidy.

Bills are due 15 days from the bill date. Pay on time for a 1.5% prompt-payment rebate, and pay online in full for a further 1%. A delayed payment surcharge of 1.5% a month starts if the bill stays unpaid 10 days after the due date.

On Subspace, open Electricity, choose North Bihar or South Bihar Power Distribution Company, enter your CA number, check the name and amount, and pay by UPI. The payment is reported to the company through Bharat Connect. Smart prepaid meters are recharged instead; see smart meter recharge.
