Currently over one million households in the Province of Riau in Indonesia, mainly in rural villages, do not have access to electricity. This dissertation was aimed to fill the gap of the lack of studies in exploiting local renewable energy resources to extend the reliable, affordable and sustainable electricity supplies for Riau’s rural villages. It identifies, designs, and analyses the feasible options that harness solar energy, hydrokinetic power from rivers and palm-biodiesel fuel for diesel generators. Along with a literature study, the HOMER simulation program was used as a technical design tool, and the I3A framework proposed by Retnanestri (2007) was adopted as a general design tool to enhance the sustainability of rural electrification programs (REPs) in Riau. Two options have been recommended to meet the future electrical load in a typical Riau rural village. The first option is a hybrid power system comprised of a photovoltaic array, Darrieus hydrokinetic turbines (DHTs), a back-up diesel generator, a battery bank, and an inverter. The second option consists of a diesel generator with biodiesel fuel. The first option met 100% of the load but the second option had around 20% capacity shortage. In the first option, the DHTs contributed 55% of the power output, indicating the viability of exploiting the river power in Riau. The first option had low O&M costs but its capital cost was high, while the second option had the opposite cost structure. The costs of energy (COEs) of both options were higher than the current electricity tariff in Riau, but would be lower than the COE of a diesel-only system. To enhance the sustainability of the REP implementations in Riau, it would be necessary to consider the Institutional issues related to Accessibility, Availability and Acceptability aspects, which simultaneously look at all features of the REP’s “hardware-software-orgware.”
