Industrial Solar in Gurugram: Tariffs, Net Metering & ROI (2026)

Direct Answer: What Does Rooftop Solar Look Like for a Gurugram Factory in 2026?

Strong. A Gurugram industrial consumer on a DHBVN HT connection pays a base tariff of ₹6.95/kVAh in energy plus ₹290/kVA/month in demand charges (11 kV) — before electricity duty, municipal tax and fuel surcharge — so the all-in landed cost typically sits in the ₹8–9.5/unit band. A well-run rooftop plant replacing that energy pays back in roughly 4–5 years and delivers low-twenties IRRs over 25 years.

Two Haryana rules shape the design: net metering is capped at 500 kW or your sanctioned load/contract demand, whichever is lower (larger systems need a separately confirmed arrangement such as gross metering), and under the 2025 Second Amendment unadjusted surplus credits at settlement are bought back at 90% of the feed-in tariff — so you size the plant to your daytime load, not your roof.

What Does a Gurugram Factory Actually Pay for Grid Power?

Gurugram is served by Dakshin Haryana Bijli Vitran Nigam (DHBVN). HERC's FY 2025-26 order (the first tariff revision in about seven years) set the HT industrial schedule below, and HERC's March 2026 press release confirmed tariffs are unchanged for FY 2026-27, so these are the rates in force:

HT supply voltage	Energy charge	Fixed (demand) charge
11 kV	₹6.95 / kVAh	₹290 / kVA / month
33 kV	₹6.85 / kVAh	₹290 / kVA / month
66 / 132 kV	₹6.75 / kVAh	₹290 / kVA / month
220 kV	₹6.70 / kVAh	₹290 / kVA / month
Arc furnaces / steel rolling (11 kV)	₹7.25 / kVAh	₹290 / kVA / month

On top of this sit electricity duty, municipal/panchayat tax and the fuel-surcharge adjustment (FSA), which is why the effective figure lands well above ₹6.95. The demand-charge line matters too: at ₹290/kVA/month, an oversized contract demand is a recurring cost — and HERC's August 2026 amendments now make it cheap and reversible to right-size it after solar. See HERC's excess-demand surcharge relief for that window.

The Time-of-Day Lever Gurugram Plants Underuse

Haryana runs a time-of-day / night-time concessional tariff for HT industry (DHBVN Sales Circular D-22/2025 for FY 2025-26). The structure rewards shifting flexible load into off-peak hours, where concessional energy rates have historically dropped to roughly ₹3.75–4.25/kVAh in the November–March night window. For a 24×7 plant — cold storage, pharma, data centre, three-shift manufacturing — combining daytime solar self-consumption with night-shift ToD arbitrage is one of the cheapest total-energy plays available in NCR. We model the interaction in time-of-day tariff and factory solar savings.

Net Metering Rules for Gurugram C&I (HERC 2021 Regulations)

Rooftop solar in Gurugram is governed by the HERC (Rooftop Solar Grid Interactive Systems Based on Net Metering / Gross Metering) Regulations, 2021, as amended in 2024 and 2025. The points a factory owner needs:

Capacity cap: system size is limited to your contract demand and to 1 MWp per eligible consumer (±5%). Above 1 MW the route is open access, not net metering.
Open-access exclusion: net metering is not available to consumers already on open access — you choose one framework.
Transformer loading: cumulative rooftop solar on a distribution transformer is capped (historically ~30% at LT, ~15% at HT), so very large shared-transformer estates can face a queue.
Gross metering is an alternative if you want to sell the entire output rather than self-consume.

For the full state framework, read our DHBVN net metering guide for Haryana industry.

How Is Surplus Solar Valued — the 2025 Second Amendment?

The December 2025 Second Amendment reset how export is settled, and it changed the sizing math:

Surplus energy injected is settled against consumption through the bidirectional meter; unadjusted credits at the end of the settlement period are purchased by the discom at 90% of the applicable feed-in tariff.
The settlement period runs 1 October to 30 September; carried-forward credits reset to zero at the start of each new settlement period.
The old 90%-of-annual-consumption generation cap is removed.

The practical conclusion is the same as in every net-billing regime: a unit you consume on-site avoids ~₹8–9.5, while a unit you export earns a fraction of that. Oversizing for export destroys returns. Size to your genuine daytime load with our factory solar sizing checklist, and treat export as a bonus.

Haryana Policy Incentives That Apply to Industry

The Haryana Solar Power Policy framework (2021, building on 2016) plus recent HERC orders add several levers:

Rooftop solar mandate: industrial and commercial establishments with connected load ≥50 kW are required to meet 3–5% of connected load from solar — many Gurugram buildings are technically already obligated. Details in our Haryana commercial building solar mandate guide.
Captive concessions: qualifying captive solar (registered with HAREDA) gets wheeling and transmission charge exemptions for 10 years, and cross-subsidy / additional surcharges do not apply to captive projects.
Green open access, widened: HERC's February 2025 First Amendment extended eligibility to 100 kW aggregated across multiple connections in the same division and removed the supply restriction for captive consumers — see the central framework in our Green Energy Open Access Rules 2022 guide and the Haryana charges in HERC open access surcharge 2026.
PM Surya Ghar fee waivers (Aug 2025): processing, meter installation and testing fees waived for scheme connections (residential-leaning, but it signals the pro-rooftop direction).

What ROI Should a Gurugram Factory Expect?

Using the tariff above and current EPC pricing, a Gurugram rooftop project typically shows:

Plant size	Indicative capex	Payback	25-yr IRR (capex)
250 kW	₹90 lakh – ₹1.05 Cr	~4.5–5.0 yrs	~18–20%
500 kW	₹1.8 – ₹2.1 Cr	~4.0–4.5 yrs	~20–22%
1 MW	₹3.5 – ₹3.95 Cr	~3.8–4.3 yrs	~21–24%

These are illustrative ranges, not a quote — the real number depends on your load factor, ToD profile, self-consumption ratio and tax position. The 40% accelerated depreciation and the AD vs 115BAA regime choice materially move Year-1 cash flow for a profitable factory. Pressure-test any proposal against our solar ROI and payback methodology.

Frequently Asked Questions

What is the DHBVN industrial tariff in Gurugram for FY 2026-27?

₹6.95/kVAh energy plus ₹290/kVA/month demand charge at 11 kV (HERC FY 2025-26 schedule, held unchanged for FY 2026-27). Electricity duty, municipal tax and FSA are additional, taking the effective cost to roughly ₹8–9.5/unit.

Is there a rooftop solar capacity limit for Gurugram factories?

Yes — net metering up to 500 kW or your sanctioned load/contract demand, whichever is lower, under HERC's 2021 rooftop regulations. Gross metering can go up to your contract demand; above these, use open access — confirm the structure with DHBVN in writing.

How is surplus solar power paid in Haryana?

Surplus is netted against consumption through the bidirectional meter; unadjusted credits at the end of the October–September settlement period are bought by the discom at 90% of the applicable feed-in tariff, and the balance resets annually.

Is solar mandatory for commercial buildings in Haryana?

Yes — industrial and commercial establishments with connected load ≥50 kW must source 3–5% of connected load from solar under the long-standing Haryana mandate.

Can a Gurugram factory use both solar and open access?

Not simultaneously for the same consumption — net metering is not available to consumers already on open access. You choose the framework that fits your load and scale.

What payback can a Gurugram factory expect from rooftop solar?

Typically 3.8–5 years depending on size and self-consumption, with 25-year IRRs in the low twenties on a capex basis — before tax benefits such as accelerated depreciation.
