- Haryana has two DISCOMs: UHBVN (north) and DHBVN (south, incl. Gurugram/Faridabad).
- HERC sets the caps, the transformer penetration limit, fees and settlement.
- Penetration limits around 50% / 30% of DT capacity are cited — verify.
- Path: apply → feasibility → agreement → bidirectional meter → commissioning.
- Every fee and cap here is an estimate — verify with HERC / your DISCOM.
Haryana net metering lets a rooftop solar customer in Gurugram, Faridabad or anywhere in the state export surplus power and earn credit for it. For an EPC, the work is to move each plant cleanly through the right DISCOM — UHBVN or DHBVN — from feasibility to a sealed bidirectional meter. This guide covers the process, the penetration limit, fees and the timeline.
Haryana net metering in brief
Haryana net metering lets a solar plant export extra units to the grid and net them against the units the customer draws. The Haryana Electricity Regulatory Commission (HERC) writes the rules, and the state's two distribution companies run them on the ground. Haryana includes the dense NCR belt around Gurugram and Faridabad, where transformer headroom is a frequent feasibility question.
The numbers EPCs watch most are the application fee and the transformer penetration cap — often cited around 50% or 30% of distribution-transformer capacity. Those come from HERC orders and DISCOM sales circulars and change; verify the current figure before you size a plant.
UHBVN and DHBVN — which serves your site
Haryana is split between two distribution companies. You apply to the one that serves the installation site, named on the customer's bill.

Net metering, net billing or gross — which applies?
Haryana has primarily offered net metering, where export is netted against import in units. The model can vary by consumer class and system size under HERC orders.
The three models in plain words
- Net metering — export is subtracted from import in units; you pay for the net units.
- Net billing — export is paid a separate, usually lower, rate; import is at the retail tariff.
- Gross metering — all generation is sold at a fixed feed-in tariff and you buy all power at retail.
Which model and export value apply to your customer is set by the current HERC regulation. Confirm it before you build a savings case. Our net vs gross vs net-billing guide explains how each one changes the payback.
Capacity caps and transformer penetration
Your system size in Haryana is tied to the customer's sanctioned load and to the headroom on the local distribution transformer (DT). The DISCOM checks both at feasibility. Haryana has used a transformer penetration rule — a cap on how much rooftop solar a single transformer can carry.
The numbers that move
Haryana has cited transformer penetration limits around 50% or 30% of DT capacity, and the application fee, set by HERC orders and DISCOM sales circulars. There is no single national DT loading number — around 30% is commonly cited, but it varies by state and feeder. Every one of these is an estimate; verify the current penetration cap and application fee with UHBVN, DHBVN or HERC before you size the plant. If the system exceeds the sanctioned load, the customer needs a load enhancement first, and our DT loading rule guide explains how penetration caps work.
Under the Electricity (Rights of Consumers) Rules 2020, systems up to a threshold (long cited as ≤10 kW) have a form of deemed feasibility — but that threshold has been debated and amended in 2024–2026, so verify the current threshold and how your DISCOM applies it.
The application process, step by step
UHBVN and DHBVN take the net-metering application against the customer's existing account number. Here is the flow an EPC follows from start to a working, metered plant.
Apply to UHBVN or DHBVN
Identify the DISCOM for the site — UHBVN (north) or DHBVN (south, incl. Gurugram/Faridabad) — and start the rooftop-solar / net-metering application against the existing account number.
Feasibility & technical check
The DISCOM checks the distribution transformer (DT) penetration, the feeder and the sanctioned load before it clears the connection size.
Sanction & sign the agreement
After feasibility clears, the DISCOM issues a sanction and you sign the net-metering agreement that sets the metering and settlement terms.
Install & inspection
Install the plant to CEA safety standards, then arrange the electrical inspection / CEI clearance where the system size requires it.
Meter install & commissioning
The DISCOM installs, tests and seals the bidirectional meter, then commissions the plant. Export only counts from commissioning.
The exact portal flow and the sequencing of the CEI / electrical inspection change with DISCOM circulars and HERC orders. Re-check the current DISCOM sales circular before you file.
Documents you need for a Haryana application
Collect the document set before you open the application. A missing or mismatched paper is the most common reason a file sits.
Indicative set — verify the current DISCOM checklist.
See our full net-metering documents checklist for the EPC-grade version that works across states.
Fees, deposits and meter cost
Haryana net metering has three money items: the application fee, a possible security deposit on any extra sanctioned load, and the cost of the bidirectional meter. The DISCOM supplies, tests and seals the meter.
The figures that change
The application-fee amount, the deposit and the meter charge are HERC and DISCOM decisions that move with each sales circular. These are estimates; verify the current fee schedule with UHBVN or DHBVN before you put numbers in a quote. Our deposit, meter and fee guide shows how to model these line items.
Timeline and commissioning
A clean Haryana net-metering case commonly runs a few weeks from feasibility to a sealed meter, but the real timeline depends on the DISCOM, the plant size, meter stock and whether a CEI inspection is needed. The NCR belt can be slower at peak season.
What happens at commissioning
At commissioning, the DISCOM installs the bidirectional meter, tests it, and seals it. Export only starts counting from that date. Compare states in our timeline by state guide. All timeline figures are estimates — verify the current schedule with your DISCOM.
Feasibility and transformer notes for Haryana sites
Feasibility decides the plant size the DISCOM will allow. Haryana applies a transformer penetration rule, so the DISCOM looks at how much rooftop solar the local distribution transformer (DT) already carries before it clears a new plant. In the dense NCR belt around Gurugram and Faridabad, transformers fill up faster, so headroom is a frequent question.
What an EPC should check before applying
- Sanctioned load — read it off the latest bill; if the plant is larger, plan the load enhancement first.
- Transformer penetration — ask the DISCOM whether the local DT is near its solar penetration limit before you commit a size.
- Phase match — a three-phase plant needs a three-phase connection; a single-phase connection caps the size.
- CEI trigger — larger systems need an electrical inspection; plan for it early.
The exact penetration figure the DISCOM applies — around 50% or 30% — is a HERC item and varies by feeder. Treat it as an estimate and verify the current penetration rule with UHBVN or DHBVN before you promise a size. An informal check saves a formal rejection later.
When it stalls — delays and escalation
Most Haryana delays come from feasibility queries, the transformer penetration limit, or a wait for the meter. First, clear the query the DISCOM raised — a corrected SLD or a load enhancement often unblocks it. If the file still sits, escalate up the DISCOM hierarchy and, if needed, raise it with HERC under the consumer grievance route.
The national Rights of Consumers Rules set time-bound expectations for connection steps, which gives you a clear basis to push. Our delay and escalation guide maps the full path. Keep a dated record of every submission.
How SuryaHub helps Haryana EPCs
Working across UHBVN and DHBVN means two sets of logins, queries and timelines, often in a busy NCR market. SuryaHub keeps the whole pipeline — from lead through the DISCOM and net-metering steps to handover — in one place, so a Haryana EPC can see exactly where each plant sits, which document is pending, and when the meter is due. SuryaHub is pre-revenue; the only real pilots are Suryantra Energy and RGESPL, and every state figure here is a scheme estimate, not a guarantee.

Frequently asked questions
How do I apply for net metering in Haryana?+
To apply for net metering in Haryana, identify your DISCOM — UHBVN or DHBVN — and start a rooftop-solar application against your account number. The DISCOM runs feasibility, you sign the agreement, install the plant, and the DISCOM tests and seals the bidirectional meter at commissioning.
Which DISCOM serves my area in Haryana, UHBVN or DHBVN?+
Haryana has two distribution companies. UHBVN (Uttar Haryana Bijli Vitran Nigam) serves the northern districts, and DHBVN (Dakshin Haryana Bijli Vitran Nigam) serves the southern districts, including Gurugram and Faridabad. Your electricity bill names the DISCOM, so apply to the one that serves the installation site.
What is the transformer penetration limit for net metering in Haryana?+
Haryana has cited transformer penetration limits around 50% or 30% of distribution-transformer capacity for rooftop solar, set by HERC orders and DISCOM circulars. The exact figure changes over time, so treat it as an estimate and verify the current penetration cap with UHBVN, DHBVN or HERC before you size a plant.
How much does net metering cost in Haryana?+
Haryana net-metering costs include the application fee, any security deposit on the extra load, and the bidirectional meter cost. The exact application fee and meter charge are set by HERC orders and DISCOM circulars and change over time, so verify the current sales circular and fee schedule with UHBVN or DHBVN before you quote.
Does Haryana use net metering or net billing?+
Haryana has primarily offered net metering, where export is netted against import in units, though the model can vary by consumer class and system size under HERC orders. The model and the export value that apply to your customer are set by the current HERC regulation, so confirm it before you build a savings case.
How long does net metering take in Haryana?+
Net metering in Haryana commonly takes a few weeks from feasibility to a sealed meter when documents are clean, but it varies by DISCOM, plant size and meter availability. Larger systems needing CEI inspection take longer. Timelines are an estimate — confirm the current schedule with UHBVN or DHBVN.
