Expanding and strengthening the grid
The PSDP comprises major investments across PNG’s electricity network. Under the project’s transmission component, the following will be delivered across Gazelle, Ramu and Port Moresby:
- Approximately 111 kilometres of new 66 kV transmission lines,
- 11 new or upgraded substations,
- Three switchyards and a SCADA system.
The project also includes the upgrade of an existing 135-kilometre transmission line from 66 kV to 132 kV in Ramu, helping improve network reliability, security and operational performance.
Complementing these upgrades is an extensive expansion of the distribution network, including more than 2,274 kilometres of new medium- and low-voltage distribution lines and mini-grid infrastructure. Collectively, these investments are designed to support PNG’s national objective of increasing electricity access, enabling PNG Power Limited to serve approximately 56,000 new customers while extending reliable electricity to peri-urban and rural communities across the country.
Delivering quality through effective construction supervision
SMEC’s multidisciplinary team provides technical leadership, design oversight and construction supervision across all stages of project delivery. This includes reviewing contractor designs, overseeing construction activities, monitoring testing and commissioning, assessing contractual milestones and supporting quality assurance processes. Our specialists work closely with PPL to identify risks early, resolve implementation challenges and maintain project momentum across multiple work fronts.
A key focus of the CSC role is ensuring that infrastructure assets are delivered to the required technical standards and are ready for long-term operation. This involves reviewing operation and maintenance programs, validating equipment performance, witnessing factory and site testing and supporting commissioning activities before assets are handed over to PPL.
Building capability for long-term success
Beyond physical infrastructure, the project places significant emphasis on strengthening institutional capability within PNG’s power sector. SMEC is supporting PPL through targeted capacity-building initiatives covering project management, procurement, asset management, operation and maintenance, environmental and social safeguards, community engagement, health and safety, and financial management.
Training programs, workshops and on-the-job mentoring are helping transfer knowledge to local counterparts, equipping PPL teams with the skills needed to manage and maintain increasingly complex power infrastructure over the long term. The project also supports initiatives aimed at increasing women’s participation in technical roles within the energy sector, contributing to a more inclusive workforce.
Supporting sustainable and inclusive development
Sustainability is embedded throughout the project. SMEC is supporting the implementation of environmental management plans, critical habitat assessments, stakeholder consultation programs and land acquisition and resettlement processes in accordance with ADB safeguard requirements. The project also incorporates social safeguard and community awareness initiatives aligned with ADB requirements, helping ensure positive outcomes for local communities throughout delivery.
Through close collaboration with PPL, government agencies, funding partners and local communities, the PSDP is helping deliver infrastructure that supports economic development while creating lasting benefits for people across PNG. As the project progresses, SMEC remains committed to delivering excellence in construction supervision and helping build a more reliable, resilient and inclusive energy future for Papua New Guinea.
