Palau cabinet energy storage system

The optimal system includes the current power system together with additional renewable capacity coupled with battery storage. The results of the optimisation show that Palau's current power system is dominated by diesel generation, with renewable energy only taking a small share (just 4%).

As there is no battery storage system currently present in Palau, the panels can only generate throughout the day when the sun is available, and no electricity can be stored for later use. Furthermore, the figure also confirms that Palau's current power system is widely dominated by fossil fuel generation.

The results of the optimisation show that Palau's current power system is dominated by diesel generation, with renewable energy only taking a small share (just 4%). With more deployment, however, the share taken by renewables could potentially increase to more than 92%. This corresponds to the lowest average system LCOE.

In conclusion, by following the recommendations outlined in this roadmap, the Republic of Palau will be on the road to achieving a fully decarbonised power system, based on solar and wind power for electricity and transport and supported by battery storage and green hydrogen. 1. INTRODUCTION TO THE PALAU ROADMAP 1.1. ROADMAP OBJECTIVE

A key recommendation for the government, if it is to achieve its proposed target of a 100% share for renewables by 2050, is to accelerate deployment of solar PV and battery storage systems through a combination of Palau Public Utilities Corporation (PPUC) investments and power purchase agreements (PPAs).
