- Bihar has two DISCOMs: NBPDCL (north) and SBPDCL (south).
- BREDA is the state nodal agency; empanelment is per-DISCOM, not portable.
- To cover the whole state you may need to register with both DISCOMs (verify).
- Systems up to 10 kW get deemed net-metering feasibility under the 2020 Rules.
- Subsidy is paid by DBT to the customer; figures here are estimates — verify with NBPDCL/SBPDCL/BREDA.
You cannot take subsidised PM Surya Ghar work in Bihar until you are empanelled with the right DISCOM. Bihar is unusual: it has two distribution companies, so where you can work depends on which one you register with. Get the empanelment and compliance right and you tap a thin, high-demand market.
What PM Surya Ghar empanelment in Bihar is
Empanelment in Bihar is how an EPC becomes an approved installer the local DISCOM lists for subsidised rooftop solar. A homeowner applies on the National Portal, the job is routed to their DISCOM, and only empanelled vendors can deliver it. If you are not empanelled, you cannot claim the subsidy work.
Three bodies matter in Bihar. The National Portal is where your firm and the homeowner both register. BREDA (Bihar Renewable Energy Development Agency) is the state nodal agency that steers the scheme. The DISCOM — NBPDCL or SBPDCL — runs the empanelment and net metering on the ground. All figures and steps below are estimates; verify the current process with NBPDCL, SBPDCL or BREDA (the Bihar state nodal agency).
Which DISCOMs cover Bihar?
Bihar has two DISCOMs under the Bihar State Power Holding Company, split by geography. This is the single most important fact for an EPC planning the state, because empanelment and net metering are handled per-DISCOM.
BREDA sits above both as the state nodal agency. The DISCOM boundaries can be redrawn, so confirm the current district split with NBPDCL, SBPDCL or BREDA before you map your sales territory.
How do you get empanelled in Bihar?
You get empanelled by registering nationally, then empanelling with the Bihar DISCOM that serves your work area. The flow mirrors the rest of the country, but the DISCOM step is local.
The four moves
First, register your firm on the National Portal, select Bihar, and upload the standard document set — PAN, GST, electrical contractor licence, cancelled cheque and trained-technician details. Second, lodge the Performance Bank Guarantee: ₹2.5 lakh for a single state covers Bihar. Third, empanel with NBPDCL or SBPDCL. Fourth, keep ALMM and DCR compliance ready so your projects pass.
Empanelment is not portable
An empanelment is tied to the DISCOM that grants it. Being empanelled with NBPDCL does not let you take subsidised jobs in SBPDCL territory, and a Bihar empanelment does not carry to another state. Our DISCOM empanelment guide explains why the empanelment never travels with you.
Why might you register with both DISCOMs?
You may need to register with both NBPDCL and SBPDCL if you want to cover the whole of Bihar. Because empanelment is per-DISCOM, one registration only opens one half of the state for subsidised work.
An EPC based in Patna sits in SBPDCL territory, so a single SBPDCL empanelment covers the south. The moment you want jobs in Muzaffarpur, Darbhanga or Purnia, you are in NBPDCL territory and need a second empanelment. Plan for two DISCOM relationships from the start if you sell statewide. Confirm whether your single-state PBG covers both DISCOMs with NBPDCL, SBPDCL or BREDA.
Start where your crews are
Most EPCs should empanel first with the DISCOM that covers their base, win jobs, then add the second DISCOM once they can send a crew across the state. Do not register with both before you can actually serve both — unserved areas invite complaints that put your empanelment at risk.
How does net metering work in Bihar?
Net metering in Bihar runs through your DISCOM — NBPDCL or SBPDCL — and follows the national rule that small rooftop systems get fast approval. The DISCOM sets the bi-directional meter that credits the power your customer exports.
Deemed feasibility up to 10 kW
Under the Electricity (Rights of Consumers) Rules 2020, systems up to 10 kW get deemed feasibility. The DISCOM is meant to treat the connection as feasible without a long technical study, so most PM Surya Ghar homes should clear net metering quickly. Larger systems may need a feasibility check.
The exact application steps, meter charges and timelines differ by DISCOM. Our net metering process guide walks through the feasibility, meter and DISCOM steps. Verify the current Bihar net-metering process and any meter charges with NBPDCL, SBPDCL or BREDA.
What ALMM and DCR rules apply in Bihar?
Bihar PM Surya Ghar projects must use modules from the ALMM list, exactly like every other state under the scheme. This is a national rule, not a Bihar one, so it is safe to plan around.
List-II cells from 1 June 2026
From 1 June 2026, ALMM List-II becomes mandatory. List-II covers solar cells, so your modules will need domestically made cells, not just domestic assembly. This tightens the Domestic Content Requirement (DCR) for the scheme. Plan module and cell sourcing early so a supply gap does not stall your Bihar pipeline.
The full detail — what List-I and List-II mean, and how DCR affects your bill of materials — is in our ALMM and DCR modules guide.
What central subsidy applies to Bihar jobs?
The central PM Surya Ghar subsidy is the same in Bihar as everywhere: ₹30,000 per kW for the first 2 kW, plus ₹18,000 for the third kW, capping at ₹78,000 for systems of 3 kW and above. It is calculated on the MNRE benchmark cost, not on your quote.
The subsidy is paid to the customer by Direct Benefit Transfer after the system is commissioned and the net meter is installed. A name mismatch across Aadhaar, electricity bill and bank account is the number-one reason a DBT fails, so check those three match before you submit. For housing societies, RWAs and group housing can claim ₹18,000 per kW for common-facility systems up to 500 kW. Any Bihar rural or state add-on on top of the central subsidy must be verified — confirm with NBPDCL, SBPDCL or BREDA, as it is volatile.
What is the Bihar market like for EPCs?
Bihar is a thin-competition market with strong latent demand, which makes it an opportunity for an organised EPC. Fewer established installers means less price pressure and more open districts than in saturated western states.
Rural demand is real, the numbers are not fixed
Bihar is largely rural, and rooftop solar appeals to households facing high bills and supply gaps. That demand is genuine, but vendor counts, district activity and any rural-specific support change often. Treat every figure you hear as an estimate until you confirm it with NBPDCL, SBPDCL or BREDA. An EPC that delivers clean jobs and manages the DISCOM paperwork well can build a strong position before competition arrives.
Two practical edges help in Bihar. First, an organised process beats local rivals who still run jobs on paper and WhatsApp; clean DISCOM files mean faster approvals and fewer rejections. Second, covering both NBPDCL and SBPDCL areas lets you bid statewide while single-DISCOM installers stay local. Both edges depend on disciplined paperwork, which is where most thin-team EPCs lose time.
When does the subsidy actually reach the customer?
The subsidy reaches the customer by DBT after commissioning and net meter installation, but the real wait is longer than the headline. The scheme target is 15 to 30 days; in practice 30 to 90 days or more is common. This is a field estimate, not an official Bihar figure.
Because the money goes to the homeowner, set expectations clearly at sale so a slow payout does not become your problem. Track each claim from commissioning to payout, and chase stuck files with the DISCOM. A useful point to share with customers: PM Surya Ghar loans are available up to ₹2 lakh at around 7% interest, which can bridge the gap until the subsidy lands — though the rate and terms are indicative and should be verified with the lender. Our subsidy claim tracking guide covers the steps from commissioning to DBT. Verify the current Bihar disbursement timeline with NBPDCL, SBPDCL or BREDA — it is volatile.
How SuryaHub helps Bihar EPCs deliver
Working two DISCOMs at once is exactly the kind of mess SuryaHub is built for. SuryaHub keeps both Bihar DISCOM logins, document sets, the PBG and renewal dates in one place, and runs each job from lead through DISCOM and net-metering steps to subsidy-claim tracking — so nothing that gates the subsidy slips, whether the job sits in NBPDCL or SBPDCL territory. SuryaHub is pre-revenue; real pilots are Suryantra Energy and RGESPL, AI features are on the roadmap, and figures here are scheme facts and estimates, not guarantees.

Frequently asked questions
How do I get PM Surya Ghar empanelment in Bihar?+
To get PM Surya Ghar empanelment in Bihar, register your firm on the National Portal, select Bihar, upload your documents and lodge a Performance Bank Guarantee. You then empanel with the Bihar DISCOM — NBPDCL in the north or SBPDCL in the south. Verify the current process with NBPDCL, SBPDCL or BREDA.
Which DISCOMs cover Bihar for PM Surya Ghar?+
Bihar has two DISCOMs under Bihar State Power Holding Company. NBPDCL covers north Bihar, including Muzaffarpur, Darbhanga, Saran and Purnia. SBPDCL covers south Bihar, including Patna, Gaya, Bhagalpur and Magadh. BREDA is the state nodal agency. Verify the current split with NBPDCL, SBPDCL or BREDA.
Do I need to register with both NBPDCL and SBPDCL?+
Likely yes, if you want to cover the whole state. Empanelment is per-DISCOM and not portable, so empanelling with NBPDCL does not let you take subsidised jobs in SBPDCL areas. To serve both north and south Bihar, register with each separately. Verify the current process with NBPDCL, SBPDCL or BREDA.
How does net metering work for PM Surya Ghar in Bihar?+
Net metering in Bihar runs through the local DISCOM, NBPDCL or SBPDCL. Under the Electricity Rights of Consumers Rules 2020, systems up to 10 kW get deemed feasibility, so approval should be quick. The DISCOM installs a bi-directional meter after inspection. Verify the current net metering process with NBPDCL, SBPDCL or BREDA.
What ALMM and DCR rules apply to Bihar PM Surya Ghar projects?+
Bihar PM Surya Ghar projects must use modules from the ALMM list, like every state under the scheme. ALMM List-II, which covers solar cells, becomes mandatory from 1 June 2026, so cells must also be domestically made. Plan your module sourcing early. See the ALMM and DCR modules guide for detail.
How long does subsidy disbursement take in Bihar?+
The central subsidy is paid by DBT to the customer's bank account after commissioning and net meter installation. The scheme target is 15 to 30 days, but in practice 30 to 90 days or more is common. This is a field estimate; verify the current disbursement timeline with NBPDCL, SBPDCL or BREDA.
