Levelized Costs of Electricity of OTEC in Halmahera
This document provides details about a proposed ocean thermal energy conversion (OTEC) project in Halmahera, Indonesia. It includes tables showing the current power needs in Maluku and North Maluku provinces, assumptions for calculating the electrical potential of a 100 megawatt OTEC plant, and variables used to estimate the payback period. The proposed land-based OTEC system in Halmahera could generate 93.1 gigawatt hours annually and have a payback period estimated through calculations accounting for factors like inflation, income, expenses, and discount rate.
