Project Description

The proposed second additional financing will leverage battery storage to facilitate expansion of solar PV-based generation systems in Rarotonga, thereby helping reduce fossil fuel consumption and enhance the level of energy security on the island. The additional GCF grant, with the additional contribution from the government of $1.71 million, will increase the overall project investment from the current $29.85 million to $43.56 million.

The Project has two outputs: (i) two-phased construction of solar photovoltaic (PV) power and/or energy storage systems on Mangaia, Mitiaro, Mauke and Atiu (Phase 1), Rarotonga and Aitutaki (Phase 2); and (ii) to provide institutional strengthening to the Cook Islands Renewable Energy Development Division (REDD). The Phase 1 subprojects will install a total of 1,246 kW of solar PV systems with battery storage. The systems at Mitiaro and Mauke will include new high speed diesel generators whilst the more modern existing diesel power stations on Mangaia and Atiu will be retained. The upgrade of the electricity distribution system is also included for all but the Atiu subproject. The Phase 2 subprojects include the installation of an additional 1,000 kW solar PV system on Aitutaki together with a new 300 kW high speed diesel and battery storage. On Rarotonga, it is the initial installation of a 1 MW, 4 MWh Battery Energy Storage System (BESS) to be complemented by a second stage of additional battery storage (R-ESS-2) with a capacity of 3 MW / 12 MWh.
