Supporting Pacific Energy Security through Hydropower

How we helped assess renewable energy potential across remote island communities

As part of the ongoing energy transition across the Pacific, Verbrec was engaged to deliver four pre-feasibility studies for hydroelectric schemes on the islands of Pohnpei and Kosrae in the Federated States of Micronesia.

These studies formed a critical first step in the region’s electrification journey, supporting a transition from diesel reliance to clean, locally sourced renewable energy. Each engagement was designed to assess how local hydro resources could strengthen energy security, diversify the energy mix and support more sustainable long-term infrastructure planning across remote island communities.

The programme focused on four proposed hydroelectric schemes across Pohnpei and Kosrae, each assessed as part of a broader strategy to support renewable development in the Federated States of Micronesia.

Verbrec’s work examined the viability of the Nanpil 2, Lehnmesi, Seniphen and Finkol projects, with each site assessed for its potential to contribute to a more secure and locally driven energy future. The studies were commissioned by the region’s primary energy provider and formed part of a wider effort to reduce diesel dependence through reliable renewable generation.

Assessing hydro potential for remote island energy systems

Each pre-feasibility study was developed to assess the technical and commercial foundations needed to advance hydroelectric infrastructure in remote and complex environments.

Verbrec evaluated the key variables that would shape future project viability, including hydrogeological flow conditions, estimated energy generation, constructability and financial feasibility. The work created a practical analytical base for future decision-making, while accounting for the logistical, environmental and infrastructure realities of island-based energy systems.

Enabling long-term renewable development in island energy systems

Laying the groundwork for cleaner, more resilient and locally sourced power

The outcomes of the studies are now informing next-stage investment planning and grid integration discussions, laying the groundwork for future FEED and detailed design phases. More broadly, the work helped establish a strong foundation for hydroelectric development that is resilient, environmentally aligned and suited to the long-term needs of remote island communities. Verbrec’s involvement supported the region’s pathway toward cleaner, more secure and more self-sustaining energy systems in the Western Pacific.
