ITP Renewables have been contracted by the New Zealand Ministry of Foreign Affairs and Trade (MFAT) to investigate the performance and provide financially justified options for augmenting the renewable energy system on Vaitupu, Tuvalu. In 2015, hybrid power systems comprising solar PV, battery energy storage, and diesel generators were installed and commissioned in Vaitupu, Niutao, Nanumea, and Nanumaga, as part of the MFAT funded Tuvalu Outer Island Solar Power Project, for which ITP provided feasibility, design and quality assurance services.

These systems were designed to supply 90+% renewable electricity on an annual basis. Subsequently, Vaitupu's electricity demand has increased. This has increased diesel fuel consumption and reduced the contribution of renewable electricity. As a result, the Tuvalu Electricity Corporation and MFAT wished to reassess the energy supply requirements for Vaitupu and recommend augmentation options for the existing power systems to meet the current and future requirements of the island. ITP modelled three scenarios of load growth and provided financially viable systems to once again provide 90+% renewable energy to Vaitupu.
