KUALA LUMPUR, 7 July 2025 – PETRONAS Gas Berhad (PGB) has successfully completed the gas-in process for its newly constructed bypass pipeline on 1 July 2025, marking the full restoration of gas supply to key areas in Batu Tiga, Shah Alam, and Connaught Bridge.
The operation began at 9:30 am with the safe introduction of gas at the Mainline Valve Stations in Puchong and Batu Tiga, followed by controlled gas-in at Putra Heights at 1:00 pm. 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). PGB is pleased to confirm that gas supply is now fully normalised, restoring energy continuity to households, businesses, and industries across the affected regions. With natural gas powering between 40% to 50% of Malaysia’s electricity, PGB remains focused on ensuring the public feels secure living near this critical infrastructure – a responsibility the company embraces as part of its commitment to safe, reliabe energy for all.
As part of its safety-first philosophy, PGB has implemented enhanced engineering reinforcements at the bypass section in Putra Heights, including advanced sensors to detect soil and pipe movements, over and above the standard requirements. To ensure long-term stability and structural integrity, sheet piling and engineered support structures have been installed to safeguard the pipeline, ensuring safe, secure, and uninterrupted performance.
In consideration of the findings from DOSH investigation and to ensure long-term resilience, PGB is designing a new permanent pipeline equipped with enhanced safety features. 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.
PGB has also carried out precautionary assessments along other sections of the 2,680-km Peninsular Gas Utilisation (PGU) pipeline to ensure system-wide integrity. These efforts involved inspection tools such as Geopig and Magnetic Flux Leakage (MFL) technology, complemented by targeted visual inspections at selected segments.
To date, no other locations have exhibited risk characteristics similar to those in Putra Heights. Monitoring efforts remains ongoing as part of PGB’s continuous integrity assurance. This proactive stance underscores the company’s unwavering commitment to transparency, continuous improvement, and longterm resilience of its infrastructure.
With the gas supply now safely restored, PGB affirms its guiding principle of Confident Coexistence – the belief that urban communities and critical infrastructure can thrive side by side when governed by the highest safety standards, transparent data, and responsible communication. This milestone marks more than just the resumption of supply – it reflects PGB’s commitment to restoring trust through facts, decisive action, and a deep sense of responsibility. In line with its mission to power the nation safely, PGB takes this responsibility seriously.
With the safe restoration of gas supply now achieved, PGB continues to reinforce its core values through decisive and compassionate action for the affected communities on ex-gratia and humanitarian grounds. Over RM2 million has been disbursed through local authorities for medical aid, property relief, and rebuilding support. To date, 55 individuals have received treatment, with RM1.38 million in financial assistance extended directly to impacted families. PGB has also contributed RM25 million via Ministry of Housing and Local Government (KPKT) for home reconstruction and is working with experts to launch a trauma and mental health support programme, with further details to be announced soon.
PGB extends its deepest appreciation to residents, local authorities, emergency services, and stakeholders for their support, patience, and cooperation throughout the recovery and restoration process. As Malaysia's leading gas infrastructure operator, the company remains committed to transparency, national energy security, and the safety of all communities near its assets.
