DHBVN Defers Net-Meter & Load-Enhancement Charges to First Bill

The Dakshin Haryana Bijli Vitran Nigam (DHBVN) has issued a circular allowing rooftop solar applicants under the Prime Minister Surya Ghar Muft Bijli Yojana (PMSGMBY) to pay net-meter and auto load-enhancement charges in the first electricity bill issued after commissioning of the solar plant, rather than upfront at the time of application. The circular, reported on 11 August 2026, is a process-simplification measure aimed at reducing the friction that has slowed rooftop solar adoption across DHBVN's operational area — which includes Gurugram, Faridabad, Rewari, and the rest of south Haryana.

DHBVN Managing Director Vikram Singh said the decision was taken to facilitate consumers, expedite scheme implementation, and simplify the application process. For Sun Wave's market — commercial and industrial rooftop solar across Delhi-NCR, Haryana, Rajasthan, and Uttar Pradesh — the circular matters because it signals DHBVN's direction on reducing rooftop solar process burden, and because the auto-load-enhancement provision removes a step that has historically delayed both residential and C&I connections.

What the DHBVN circular changes

Under the previous process, consumers applying for rooftop solar under PM Surya Ghar had to pay the net-meter charge and the auto load-enhancement charge (ACD) separately at the time of application, often requiring repeated visits to the discom office. The new circular gives applicants two payment options:

1. Pay upfront at application — the traditional route, where ACD is deposited at the time of submission.
2. Pay in the first bill after commissioning — the new route, where the charges are added to the first electricity bill issued after the solar plant is commissioned and inspected.

The second option removes the upfront cash outlay at the application stage and consolidates the charge into the normal billing cycle.

The auto-load-enhancement provision

A second, operationally significant change: DHBVN will now handle load augmentation on behalf of the applicant as part of the solar application, eliminating the need for a separate load-enhancement application. According to DHBVN Executive Engineer Dharmendra Ruhil, the discom will process the load increase internally alongside the rooftop solar connection, so consumers no longer navigate two parallel processes.

This matters because load enhancement has been a documented bottleneck in Haryana rooftop solar — applicants needing to increase their sanctioned load to accommodate a larger solar system previously had to file and track a separate petition. Bundling it into the solar application compresses the timeline.

How the billing integration works

The circular specifies the operational flow for the deferred-payment option:

• After the solar plant is commissioned, the Sub-Divisional Officer (SDO) prepares a sundry bill for the net-meter and load-enhancement charges.
• The sundry bill is forwarded to the Superintending Engineer (SE) or Chief Commercial Officer (CBO) office, which integrates the charges into the consumer's first electricity bill.
• The commercial wing sends a Management Information System (MIS) report to the CBO office for cross-checking, ensuring the charges are correctly captured in the first bill without error or delay.

DHBVN has also updated its solar portal to support the new workflow end-to-end.

Context: Haryana's broader rooftop solar momentum

The DHBVN circular is the latest in a sequence of 2026 policy and process moves across Haryana that collectively lower the friction of rooftop solar in the state:

• HERC tariff freeze for 2026-27 (March 2026): power tariffs held unchanged for the fiscal year, keeping the grid-supply benchmark against which rooftop solar savings are measured stable.
• HERC excess-demand surcharge relief (August 2026): consumers drawing up to 110% of contract demand no longer pay a surcharge (previously triggered at 105%), with a graded 20% surcharge for 110–115% and 25% beyond — covered in detail in our HERC excess-demand surcharge relief guide.
• HERC load restoration rules (August 2026): reduced-load requests without voltage change capped at a ₹20,000 processing fee, with restoration of original load within three years without fresh service connection charges.
• 90% generation cap removal: Haryana removed the cap that limited rooftop solar settlement to 90% of annual consumption, enabling full compensation for surplus units fed to the grid.
• State target of 2.22 lakh rooftop installations by 2027 under PM Surya Ghar, with revised SOP and interest-free financial assistance.

What this means for C&I buyers

The DHBVN circular applies directly to PM Surya Ghar applicants, which is a residential scheme. Three implications are nevertheless relevant for commercial and industrial rooftop solar buyers in DHBVN territory:

1. Process direction signal. DHBVN is actively removing upfront-payment and dual-application friction from rooftop solar. While the C&I net-metering process is governed by the HERC rooftop solar regulations and DHBVN's industrial connection procedures rather than the PM Surya Ghar SOP, the discom's demonstrated willingness to streamline suggests the broader application experience will continue to simplify.

2. Auto-load-enhancement precedent. The bundled load-augmentation model — where the discom processes the load increase as part of the solar application rather than requiring a separate petition — is a process improvement C&I buyers have sought for years. If DHBVN extends the principle to industrial connections, it would materially shorten C&I rooftop solar timelines.

3. Market momentum. Haryana's 2.22 lakh installation target, the revolving fund for rooftop solar, and the sequence of process simplifications create a denser and more experienced local solar ecosystem — more empanelled vendors, faster inspection cycles, more practiced SDO offices — which indirectly benefits C&I project execution in the same discom area.

How Sun Wave is responding

Sun Wave's project desk tracks every DHBVN circular and HERC amendment, and updates our C&I application workflows accordingly. For clients in DHBVN territory — particularly the industrial belts of Faridabad, Gurugram, Rewari, and Manesar — we are reviewing how the auto-load-enhancement model can be leveraged where the C&I connection process intersects with residential-adjacent load categories, and we are preparing for any extension of the deferred-payment principle to industrial net-metering applications.

The circular does not change the HERC regulatory framework for C&I net metering, nor does it alter the tariff or settlement mechanics covered in our existing DHBVN and Faridabad guides. It is a process-layer change that reduces friction for one segment of the market and signals the discom's direction for the broader rooftop solar ecosystem.

Frequently Asked Questions

What does the DHBVN August 2026 circular change for rooftop solar applicants?

It allows rooftop solar applicants under the PM Surya Ghar Muft Bijli Yojana to pay net-meter and auto load-enhancement charges in the first electricity bill after the solar plant is commissioned, instead of upfront at application. Applicants can still choose to pay upfront if they prefer. DHBVN also now handles load augmentation as part of the solar application, removing the need for a separate load-enhancement petition.

Does the DHBVN circular apply to commercial and industrial rooftop solar?

The circular is issued under PM Surya Ghar, which is a residential scheme, so the direct deferred-payment benefit applies to residential applicants. However, the auto-load-enhancement process model and DHBVN's broader direction toward reducing rooftop solar friction are relevant context for C&I buyers in DHBVN territory. C&I net metering remains governed by the HERC rooftop solar regulations and DHBVN's industrial connection procedures.

Who issued the DHBVN circular and when?

The circular was issued by DHBVN and reported on 11 August 2026. DHBVN Managing Director Vikram Singh announced the decision, and Executive Engineer Dharmendra Ruhil confirmed the auto-load-enhancement provision. The discom has updated its solar portal to support the new workflow.

How does the deferred-payment billing work?

After commissioning, the SDO prepares a sundry bill for the net-meter and load-enhancement charges, forwards it to the SE or CBO office, and the charges are integrated into the consumer's first electricity bill. The commercial wing sends an MIS report to the CBO for cross-checking to ensure accurate capture.

How does this fit with Haryana's other 2026 rooftop solar changes?

It sits alongside the HERC tariff freeze for 2026-27, the excess-demand surcharge relief (no surcharge up to 110% of contract demand), simplified load reduction and restoration rules, removal of the 90% generation cap, and the state's 2.22 lakh installation target by 2027 — collectively lowering rooftop solar friction across Haryana.

Bottom line for Haryana rooftop solar

DHBVN's August 2026 circular is a pragmatic process fix: defer the upfront charges, bundle the load enhancement, and let the billing system absorb the payment after commissioning. While the direct benefit is scoped to PM Surya Ghar applicants, the circular confirms DHBVN's direction toward lower-friction rooftop solar — a direction that benefits the entire Haryana solar ecosystem, including the C&I segment Sun Wave serves. For any rooftop solar project in DHBVN territory, the operational takeaway is to confirm the applicable payment route at application and ensure the load-enhancement step is bundled rather than filed separately.
