An industry committee set up by PNGRB has recommended that every new piped-gas connection in India be fitted with a prepaid, remotely-shut-off smart meter within six months of a rule change, and that every existing meter be swapped over on a four-phase schedule running to 2030. Read in full, the committee's July 2026 report is candid about why: a 9% average default rate on conventional postpaid gas bills is costing city-gas companies money, and prepaid smart metering fixes that for them, not primarily for the consumer. This piece reports what the committee's report actually recommends, what it costs, and who its own text says should pay for it.
PNGRB Wants Prepaid Smart Meters on Every New Gas Connection From 2027, All of Them by 2030
The short version. PNGRB's Industry Committee on smart domestic PNG (piped natural gas) metering — chaired by the regulator's own Secretary, with the managing directors of Torrent Gas and Indraprastha Gas and the COO of Indian Oil Adani Gas as members — has recommended making prepaid smart meters mandatory for every new city-gas connection within six months of a regulatory amendment, and replacing every existing conventional meter on a four-year schedule ending 1 April 2030. The committee's own numbers show why city-gas companies want this: roughly 9% of conventional-meter customers default on their bills, at an average outstanding of ₹8,500 each, and a smart, prepaid meter removes that risk entirely by charging in advance. The committee explicitly recommends that the extra cost of smart meters — five to nine times a conventional meter's price — be borne by the gas companies, not passed to consumers, though nothing here is binding until PNGRB actually amends its regulations.
Who wrote this, and why
PNGRB constituted the committee under Order PNGRB/Tech/18-PNGMeterImpl./(6)/2025, dated 17 June 2025, chaired by Shri Anjan Kumar Mishra, Secretary, PNGRB, with Shri Manoj Jain (Managing Director, Torrent Gas), Shri Kamal Kishore Chatiwal (Managing Director, Indraprastha Gas) and Shri Bhashit Dholakia (COO, Indian Oil Adani Gas) as members, and Shri Gagan Aggarwal (Deputy Director I/C Technical, PNGRB) as convener. Its terms of reference: compare smart and conventional domestic PNG meters on accuracy, reliability, safety and lifecycle cost; propose financial models and an implementation roadmap; and review the existing technical-standards framework and recommend changes to enable smart metering. The committee held a kick-off meeting on 30 June 2025, met smart-meter manufacturers on 15 July 2025, met city-gas distribution (CGD) entities on 5 August 2025, and visited the IGL Genesis smart-meter manufacturing facility in Noida on 18 September 2025 before finalising its report in July 2026.
Three kinds of smart meter, and the one the committee actually recommends
The report compares four meter types. Conventional diaphragm meters (the mechanical kind installed in most homes today) measure gas by positive displacement through flexible chambers, with an accuracy class of ±1.5% under PNGRB's cited standard (EN 1359). Smart diaphragm meters keep that same mechanical measurement but add sensors, electronics and communications for remote reading, prepaid billing and tamper detection, at the same ±1.5% accuracy. Thermal mass flow meters measure gas electronically by heating it slightly and reading the temperature difference, claiming 2% maximum error at high flow (worse, around 3.5%, at low flow) with no moving parts. Ultrasonic meters measure flow by timing sound pulses across the gas stream, and can hit ±1% or even ±0.5% accuracy with no moving parts at all.
Despite thermal mass flow and ultrasonic meters' technical edge, the committee's recommendation is for smart diaphragm meters as the default for nationwide rollout, on cost and readiness grounds: they combine "proven diaphragm-based accuracy and reliability with smart functionalities," are compatible with existing infrastructure, and can draw on "an established domestic manufacturing ecosystem" that the pricier alternatives don't yet have at the same scale.
What it costs, in the manufacturers' own numbers
Manufacturers submitted two pricing structures directly to the committee. Under a CAPEX-plus-OPEX model, per-meter figures (excluding GST, for orders above 1 lakh units) ran: a thermal-mass-flow manufacturer at ₹8,350 total upfront capex and ₹75 a month in ongoing costs (cloud hosting, communications, operations); one diaphragm-meter manufacturer at ₹4,950 upfront and ₹56 a month; another diaphragm manufacturer at ₹4,660 upfront and ₹37 a month. Under an alternative TOTEX (total expenditure) model spreading all costs, including installation and ten years of connectivity and backend support, into a single monthly per-meter charge, quotes ran ₹150–160 a month (thermal mass flow) against ₹84–90 a month (diaphragm), plus a separate battery-replacement cost of ₹800–1,000 a meter once every roughly ten years. By comparison, the report notes a conventional G1.6 diaphragm meter retails for roughly ₹800–1,000 in India with no ongoing cost at all — CGD entities themselves told the committee smart meters currently cost five to nine times as much as the conventional meters they'd replace.
The case CGD companies made: defaults, not accuracy
The committee's own framing is unusually direct about who benefits most. Data submitted by CGD entities put the industry-average default rate on conventional postpaid meters at about 9%, ranging as high as 30% in some areas, with an average outstanding balance of ₹8,500 per defaulting customer, a further ₹2,700 in recovery or disconnection costs per defaulter, and ₹220 a year in manual-billing costs per conventional meter. A prepaid smart meter, which charges before gas is supplied and can shut itself off remotely, removes essentially all of that exposure. The committee's own conclusion: "City Gas Distribution (CGD) entities emerge as the primary beneficiaries of Smart Domestic PNG metering," and consequently its recommendation is that the additional cost "should not be passed on to consumers and may be borne by CGD entities" — a recommendation, again, not yet a binding rule.
The rollout the committee wants
Two separate tracks. For new connections: within six months of PNGRB notifying the relevant amendment to its T4S Regulations, every new domestic PNG connection nationwide must be fitted with a prepaid smart meter from the outset. For the stock of already-installed conventional meters, a four-phase replacement schedule, with priority given to billed (as opposed to unbilled or dormant) connections in the first two phases:
| Phase | Financial year | Target |
|---|---|---|
| I | FY 2026-27 | 5% of billed connections |
| II | FY 2027-28 | 15% of billed connections |
| III | FY 2028-29 | 25% of total connections |
| IV | FY 2029-30 | Remaining total connections |
The report states plainly: "All DPNG meter[s] post 01 April 2030 should be Smart meters only." On manufacturing capacity, the committee found no supply-side constraint: it puts India's annual manufacturing capacity at roughly 35 lakh diaphragm-based smart meters and roughly 3 lakh thermal-mass-flow meters a year, against roughly 10 lakh new domestic PNG connections added annually — comfortably enough, on the committee's own arithmetic, to support the rollout without a supply bottleneck, even before accounting for the much larger replacement volumes the four-phase schedule implies.
The regulatory and technical gaps the committee flagged
Beyond cost and scheduling, the report recommends: amending PNGRB's T4S Regulations, 2008 to explicitly cover smart-meter technical standards (it proposes adopting IS 14439 Part 2 for diaphragm meters, the European EN 16314 standard for additional smart functionalities across all meter types, and a common communication and data protocol) and amending the CGD Authorisation Regulations to address the cost treatment of smart meters; a PNGRB collaboration with the Bureau of Indian Standards on a dedicated Indian standard for smart PNG meters, since manufacturers currently follow inconsistent communication protocols with no interoperability; a PNGRB collaboration with the National Informatics Centre on a common, secure data-communication protocol, partly to address cybersecurity and partly to prevent a manufacturer locking a CGD entity into its own proprietary system; a review of the ₹9,000 interest-free refundable security deposit currently charged for a smart-meter domestic PNG connection, which the committee flags as a friction point for consumer uptake; and a recommendation to cap two-way communication to once every 24 hours, trading a little real-time responsiveness for meaningfully longer battery life (manufacturers' own datasheets claim 8–10 years under normal use, but more frequent communication shortens that). On financing, beyond the CAPEX/TOTEX choice, the committee recommends industry-coordinated bulk procurement to capture scale economies, promoting local manufacturing under the Make in India programme, and government exploration of Viability Gap Funding and a Production-Linked Incentive scheme specifically for smart PNG meter manufacturers.
What doesn't follow from any of this
None of this is law yet. Every deadline, percentage and mandate above is this committee's recommendation to PNGRB, not a notified amendment to the T4S or CGD Authorisation Regulations — the report itself calls for those amendments as a precondition, and PNGRB could adopt the recommendations unchanged, water them down, delay them, or decline to act at all, as regulators sometimes do with committee reports. Nor does the "5 to 9 times costlier" comparison mean smart metering is a bad deal for CGD entities: the committee's own case is that the ongoing savings from eliminated defaults, recovery costs and manual billing can outweigh the higher upfront and monthly cost over a meter's lifetime, though this piece has not independently modelled whether that math holds at every CGD entity's actual default rate. And the committee's recommendation that costs fall on CGD entities rather than consumers is exactly that — a recommendation this report makes, not a guarantee of how the cost will actually be allocated once implementation details are worked out.
Sources and caveats
This piece is based on a direct, complete reading of PNGRB's "Report on Roadmap for Implementation of Smart Domestic PNG (DPNG) Metering Across India," supplied to this piece as a file rather than found via search; every figure above traces to a specific page, table or recommendation in that report, which this piece has quoted or closely paraphrased. This piece could not independently verify the manufacturer pricing quotes, the CGD entities' self-reported default-rate data, or the manufacturing-capacity figures against any third-party source — all of it is exactly what the report itself states industry participants told the committee, not independently audited data. The report anonymises its three responding manufacturers as "Manufacturer A/B/C" and does not name them; this piece does the same. Because the mandate described here is a committee recommendation rather than a notified regulation, a reader who needs to know the current legal status of smart PNG metering requirements should check PNGRB's T4S Regulations, 2008 and any subsequent amendment directly, rather than treat this piece's account of the committee's recommendations as describing current law.
