ABSTRACT
This paper aims to solve the state's hydropower dependence, build energy security and reduce greenhouse gas emissions through a hybrid renewable energy system and its implementation in Willingdon Island. Hybrid Optimisation of Multiple Energy Resources (HOMER) is used to find the optimal solution for two grid-connected and off-grid scenarios. Of the 19 solutions, an optimal off-grid, an optimal grid-connected, a 100% variable renewable energy, and a diversified energy portfolio option are selected, analyzed, and ranked based on their techno-economic and emissions characteristics. The results suggest the combination of PV/Wind/Grid with a cost of energy of $0.044 as an optimal solution for the Island. The diversified energy solution takes the second position, having 51.4% and 38.8% solar and wind, respectively.
