Bihar Electricity Bill Payment: How to Pay Online Easily
Bihar electricity bill payment is handled by two separate distribution companies depending on where you live: North Bihar Power Distribution Company Limited (NBPDCL) for northern districts, and South Bihar Power Distribution Company Limited (SBPDCL) for southern districts including Patna, Gaya, and Bhagalpur, both operating under the parent company Bihar State Power Holding Company Limited (BSPHCL). The good news is that regardless of which one serves your area, the payment process is nearly identical, and since August 2025, over 1.67 crore Bihar households have been receiving the first 125 units of electricity completely free every month, a detail that meaningfully changes how much you actually owe before you even open the payment screen.

How to check which board serves you: NBPDCL or SBPDCL
Since the process is nearly identical, the only real decision point is confirming which company issues your bill. Your bill itself will clearly show either "NBPDCL" or "SBPDCL" at the top, or you can identify it by your district: northern Bihar districts fall under NBPDCL, while Patna, Gaya, Bhagalpur, and most southern districts fall under SBPDCL.

Understanding Bihar's 125-unit free electricity scheme
Since August 2025, all domestic consumers in Bihar receive the first 125 units of electricity free every billing cycle, a scheme benefiting over 1.67 crore households across the state. This means your payable amount reflects charges only for consumption beyond 125 units in that billing period. If your household consistently uses under 125 units monthly, particularly relevant for smaller homes or those already using efficient appliances, your bill payment amount may be minimal or even zero, though you should still check and confirm this through the portal each cycle rather than assuming.

Why even Bihar's low-cost electricity is worth reducing further with solar
Bihar's 125-unit free scheme is a genuinely helpful policy, but it doesn't eliminate your bill entirely if your household, like most with a refrigerator, fans, lighting, and a TV running through Bihar's hot summers, consistently uses more than 125 units monthly. For consumption above that threshold, you're paying standard tariff rates on every additional unit, month after month, indefinitely.
Why solar makes sense even with the free-unit scheme in place:
A rooftop solar system doesn't compete with or replace the 125-unit free scheme; it works alongside it by reducing your consumption from the grid specifically for the units beyond the free allowance, the portion you're actually paying for every month. For a household regularly using 250-300 units monthly, a modest 2-3 kW solar system can meaningfully offset the paid portion of your bill, on top of the free units you already receive, while remaining eligible for the PM Surya Ghar central subsidy of up to ₹78,000 for systems 3kW and above.
Household consumption | Bihar free scheme covers | Solar can offset the remainder |
|---|---|---|
Under 125 units/month | Entire bill (already free) | Solar not urgently needed |
200-300 units/month | First 125 units free | 2-3 kW system can offset most of the remaining paid units |
400+ units/month | First 125 units free | 4-5 kW system recommended for the higher paid consumption |
If your Bihar household regularly pays for units above the free threshold, Adwin's solar and battery solutions can help you size a system that works alongside the state scheme rather than in place of it.

Visit nbpdcl.co.in or sbpdcl.co.in depending on your district, click 'Instant Payment' then 'View & Pay Bill', enter your CA Number, and complete payment via UPI, card, or net banking. Alternatively, use the official Suvidha app or NBPDCL's dedicated BBBP app.
What is the difference between NBPDCL and SBPDCL?
NBPDCL (North Bihar Power Distribution Company) and SBPDCL (South Bihar Power Distribution Company) are the two subsidiary distribution companies under BSPHCL, dividing Bihar's electricity distribution by geography. NBPDCL covers northern districts; SBPDCL covers southern districts including Patna, Gaya, and Bhagalpur. The bill payment process is nearly identical for both.
What is Bihar's 125 unit free electricity scheme?
Since August 2025, all domestic consumers in Bihar receive the first 125 units of electricity free every billing cycle, benefiting over 1.67 crore households. Charges apply only to consumption beyond this 125-unit threshold in each billing period.
What is a CA number for Bihar electricity bill payment?
A CA (Consumer Account) Number is your unique account identifier printed on your Bihar electricity bill, required to fetch and pay your bill online through the NBPDCL/SBPDCL website or official apps.
Can I pay my Bihar electricity bill without internet access?
Yes. Bihar electricity boards offer offline payment through Revenue Collection Counters at divisional and sub-divisional offices, as well as Self-Service Kiosks accepting cash or card payments at many local offices, for consumers without reliable internet access.
What is the Suvidha app used for in Bihar electricity billing?
Suvidha is the official mobile app of BSPHCL (Bihar State Power Holding Company Limited), usable for both NBPDCL and SBPDCL bill payments, offering bill viewing, payment history, and instant payment options with or without registration.

Does Bihar's 125-unit free scheme apply to solar-powered homes too?
The free unit scheme applies to grid electricity consumption specifically. If you install rooftop solar, you'll draw fewer grid units overall (since solar generation offsets your usage), meaning the 125 free units go further, and you're less likely to exceed the free threshold and incur charges at all.
