KUALA LUMPUR (July 6): Petronas Gas Bhd (KL:PETGAS), the country's leading gas infrastructure operator, has announced the full restoration of gas supply to key areas in Batu Tiga, Shah Alam, and Connaught Bridge. This follows the successful commissioning of a newly constructed bypass pipeline on July 1, after the April 1 explosion incident at Putra Heights, Selangor.

The resumption of full supply is critical to restoring energy continuity for households, businesses, and industries across the affected areas.

With natural gas contributing 40% to 50% of Malaysia’s electricity generation, PetGas said it remains focused on ensuring that the public feels secure living near this critical infrastructure.

PetGas has also carried out precautionary assessments along other sections of the 2,680-km Peninsular Gas Utilisation (PGU) pipeline, to ensure system-wide integrity. It confirmed that no other locations have exhibited risk characteristics similar to those in Putra Heights to date.

"Monitoring efforts remain ongoing as part of PetGas’ continuous integrity assurance. This proactive stance underscores the company’s unwavering commitment to transparency, continuous improvement, and long-term resilience of its infrastructure," the company said in a statement issued late evening on Sunday.

In response to the incident, PetGas has installed a suite of enhanced safety features at the bypass section in Putra Heights. These include advanced sensors for soil and pipeline movement detection, structural reinforcements such as sheet piling, and engineered support systems — all exceeding standard regulatory requirements.

PetGas said the gas-in operation — a critical step to safely reintroduce natural gas into the new bypass system — began at 9.30am, with gas introduced at the mainline valve stations in Puchong and Batu Tiga, and later at Putra Heights at 1pm. Flow levels were gradually increased from 10% to 100% in phases, and fully stabilised by 12:00 midnight, following strict safety procedures.

"The commissioning was carried out after fulfilling all engineering, operational, and regulatory safety requirements, including the issuance of the permit to operate (PTO) by the Department of Occupational Safety and Health (DOSH)," it added.

In consideration of the findings from the DOSH investigation and to ensure long-term resilience, PetGas said it is designing a new permanent pipeline, equipped with deep piled slab foundations and advanced shut-off valves. This will allow for quicker isolation in the event of emergencies, and improve structural resilience amid ongoing land development in the area.

"The pipeline will be installed on deep piled slab foundations, offering greater structural resistance to soil movement or unpredictable ground shifts, considering the risks specifically in this area due to the surrounding development. The layout will also feature new shut-off valves, to allow for shorter distance of isolation in an unlikely event of emergency The original site has already undergone stabilisation works, and only two key pipelines will remain — a decision made to significantly reduce risks, and maintain long-term safety and community confidence."

With the safe restoration of gas supply now achieved, PetGas said it has committed substantial humanitarian aid to affected communities. Over RM2 million has been distributed through local authorities for medical assistance, property relief, and rebuilding efforts.

To date, 55 individuals have received treatment, with RM1.38 million in financial assistance extended directly to impacted families, it added.

The company has also contributed RM25 million via the Ministry of Housing and Local Government for home reconstruction, and is working with experts to launch a trauma and mental health support programme, with further details to be announced soon.

PetGas shares closed down 12 sen or 0.66% at RM18.04 on Friday, giving it a market capitalisation of RM35.7 billion. The stock has risen by a marginal 0.56% so far this year.
