EAST ASIA AND PACIFIC: Developing RE Storage System for Pacific Island Countries

Pacific Island countries face major challenges transitioning to renewable energy systems. These island nations are highly vulnerable to climate change but rely heavily on costly imported fossil fuels. This leads to high emissions and a heavy economic burden. Renewable energy can alleviate these difficulties, but integrating solar and wind power into their power grids requires overcoming technical and financial hurdles.

To address these issues, PPIAF supported an analysis to determine options for integrating renewable energy and battery storage energy systems (BESS). The study mapped out PPP models tailored to the context of each country.

The findings and recommendations were included in a report that outlined various variable renewable energy scenarios with specific PPP structures. Options included variable renewable energy combined with BESS, leasing of BESS, mini-grid concessions, and more. The report was shared with the Pacific Power Association and the utilities of each Pacific Island country. Some larger power companies now plan to incorporate the PPP models into their renewable energy strategies.

The analysis will help Pacific Island countries fulfill their Paris Agreement commitments to reduce emissions by phasing out expensive imported diesel. Renewable mini grids and solar battery systems are starting to come online, slashing fuel costs and emissions while increasing access to energy.

While each island faces unique circumstances, they now have common tools to achieve an energy future free of costly fossil fuel imports. With PPIAF’s support, Pacific Island countries can transform their energy systems and become models of sustainability.
