The Government of Vanuatu needed assistance with the preparation of a renewable energy investment plan, which would be used to apply for funding through the Climate Investment Funds Scaling Up Renewable Energy Program (SREP). The objectives of the Investment Plan were to bring together all prior analyses of renewable energy carried out in Vanuatu, and to carry out more in-depth resource and financing modeling to identify the best renewable energy options in Vanuatu. The project involved the assessment of the potential for developing the following renewable resource options: wind power, solar PV and solar thermal power, geothermal power, biomass and biofuels, solar-based microgrids and pico solar. It also involved working with a diverse set of national and international stakeholders from industry, academia and government to choose renewable energy options for investment.
