The Philippines has joined Vietnam and Indonesia in a new regional partnership aimed at accelerating the clean energy transition in remote and island communities. The initiative, launched on November 10 at the COP31 Philippine Hub in Antalya, Türkiye, will focus on replacing expensive diesel-powered generators with solar photovoltaic (PV) systems and battery energy storage solutions.
The partnership aims to improve electricity access, reduce dependence on imported fossil fuels and lower power generation costs in isolated communities. It will also encourage regional cooperation to develop renewable energy projects that can provide reliable and affordable electricity to underserved populations.
During the launch event, Department of Energy Undersecretary Felix William Fuentebella announced that the Philippine government is planning to integrate island electrification into its Green Energy Auction program. The proposed approach would allow renewable energy developers to participate in auctions designed to support clean power generation in off-grid areas. However, specific auction rounds, implementation timelines and capacity allocations have not yet been finalized.
The need for this transition is highlighted by the country’s existing dependence on oil-based power generation. According to official data, as of December 2025, approximately 94% of the Philippines’ off-grid power plants, representing 421 out of 447 facilities, continued to rely heavily on oil. This dependence results in high electricity generation costs and limits the availability of reliable power in several remote communities.
Successful pilot projects demonstrate the potential benefits of solar and battery storage systems. On Cobrador Island in Romblon, a 30-kilowatt solar-plus-battery hybrid installation reduced electricity generation costs by nearly 50%, from $0.47 to $0.24 per kilowatt-hour. The project also increased electricity availability from just eight hours daily to continuous 24-hour service.
Regional research, including studies by Indonesia’s Institute for Essential Services Reform, suggests that combining solar power with battery storage can deliver electricity at approximately one-third of the cost of conventional diesel generation.
Beyond individual projects, the partnership between the Philippines, Vietnam and Indonesia will promote coordinated planning, private investment, supportive regulations and technical capacity development. The initiative aims to transform successful island electrification pilots into scalable renewable energy projects.
Through regional collaboration and greater deployment of solar and battery storage, the participating countries seek to improve energy affordability, strengthen electricity reliability and support long-term climate resilience in remote communities.
