This report presents the findings of a feasibility study of a Waste to Energy Plant for Rarotonga. The report was developed by DNV KEMA for Te Aponga Uira (TAU) to assess the need and feasibility for a Waste to Energy plant for the Island of Rarotonga. The assignment is to scope and undertake research work of available sources of waste being generated from Rarotonga and components of producing energy from waste connected and operating in synch with the TAU power network. The Cook Islands enjoyed a high level of electrification. However, the energy supply has been heavily dependent on imported fossil fuels, exposing the Cook Islands to the risks of energy security and international oil price volatility.
