Palau Antimony Battery Energy Storage

Palau on June 3 launched its first solar and battery energy storage system (BESS) project on Friday. The project was made possible by Renewable company Alternergy Holdings Corp. and its subsidiary Solar Pacific Energy Corporation.

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 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%).

energy storage system, was undertaken by Solar Pacific Pristine Power, a privately owned company. The plant will provide approximately 20 per cent of Palau's power needs, delivering up to 23,000 megawatt hours per year to the grid network, reducing Palau's reliance on expensive diesel generators.

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.
