IGL Starts Digital CNG Hydrotest Checks in Delhi: What Owners Should Know

IGL’s new CNG hydrotest checks in Delhi bring cylinder-certificate verification into the refuelling queue. The reported rollout uses number-plate recognition and digital certification records to flag expired or invalid hydrotest status before fuel is dispensed. It was inaugurated at the Shantipath CNG station on 21 October 2026, with wider Delhi-NCR deployment planned. For motorists, the practical takeaway is to check certificate validity before reaching a participating pump. The rollout does not establish that every IGL station already has the system.

What CNG owners need to know

• What changes: a vehicle’s registration plate can be recognised and matched with hydrotest certification status.

• What can stop refuelling: an expired or invalid certification status can trigger an alert to station staff.

• What drivers can check: the Nawgati Fuelling App provides hydrotest-status information and a compliance pass.

• What remains unclear: a complete participating-outlet list and a dated Delhi-NCR expansion schedule have not been established.

How the station checks work

The system connects vehicle recognition with certification information on the PESO portal. Instead of relying only on a person looking at a certificate, the verification pipeline can send alerts to handheld devices, LED displays and public-address systems. Station staff then have information to stop vehicles with unverified certification from refuelling.

Three tools perform different jobs. The Nawgati Fuelling App gives motorists visibility into their status. The Aaveg Compliance App supports handheld checks by staff and queue marshals. The Aaveg System recognises number plates at the station and displays hydrotest status.

Digital verification is different from hydrotesting

The announcement concerns checking an existing certification record. A camera or an app does not physically test a cylinder, renew an expired certificate or establish the condition of the fuel system. A compliance pass should therefore be understood in the context of the recorded certification status.

This distinction matters when planning a visit to the pump. Seeing a digital check at a station should not be mistaken for being offered a cylinder-testing service there. Owners who need testing or record correction should confirm the appropriate process with their authorised testing provider or the operator.

A practical check before visiting a participating pump

1. Review your certificate: check the vehicle details and the validity recorded on your hydrotest documentation.

2. Check the digital status: where available, compare the app’s status with your current documents before travelling.

3. Resolve a mismatch early: if your records disagree, ask the operator or testing provider how to correct the discrepancy. Do not assume staff can override an alert.

These are preparation steps, not a guarantee of refuelling approval. The checked announcement does not set out a detailed dispute-resolution process, correction time or charge, so those details should be confirmed for the individual case.

Why the Delhi rollout matters

Checking certification while vehicles are in the queue can make an expired or invalid record visible before dispensing begins. For an owner, that creates an immediate reason to keep documentation current and consistent. For station operations, the reported benefit is a shared digital alert rather than a purely manual check.

However, the scope remains important: the launch refers to key Delhi stations, followed by planned expansion. It does not support a claim that the system is active at every IGL outlet or throughout the NCR.

FAQs

Will an expired hydrotest status stop CNG refuelling?

The reported system alerts station staff when certification is expired or invalid, enabling them to stop unverified vehicles from refuelling at participating stations.

Can the app renew my cylinder’s hydrotest certificate?

The announced app displays status and a compliance pass. The rollout does not describe app-based renewal or a replacement for physical hydrotesting.

Is this available at every IGL station?

That has not been established. Deployment at key Delhi stations and a plan for wider Delhi-NCR expansion are reported; a complete outlet list was not provided.

IGL’s CNG hydrotest verification rollout makes certificate readiness more relevant to the journey to the pump. Check the validity and matching records early, while watching for confirmed outlet coverage and expansion details.
