Abstract:
The Philippines is an island archipelago where most of the inhabited islands currently enjoy only limited hours of electricity, generated by unsustainable, expensive and environmentally hazardous diesel powered plants. The core objective of this thesis is to prove that energizing islands in the Philippines through - renewable energy sources - will in the long run be more cost efficient than power generation through conventional diesel power plants. This thesis analyses current government policies and objectives in rural electrification in the Philippines; it also describes the legal framework and incentives available, and feasible business models that enable implementation of hybrid renewable energy mini-grids. The current electrification situation and key stakeholders, specifically in rural electrification and available renewable energy resources in the Philippines, are assessed and put into context with the goal of accelerated implemention of renewable energy mini-grids. An actual case study for the electrification of one specific remote island, using the energy modeling software HOMER, has been conducted. The two HOMER simulations, applying two different sets of future load assumptions, both prove that power generation through renewable energy lowers the cost of generation in the specific island. This thesis shall also contribute to wider implementation of renewable energy power generation systems in the Philippines through contributing to a thorough understanding of the government policies supporting rural electrification, presentation of feasible business models and the evidence that electrification through renewable energy is the least-cost electrification option available.
