Techno-economic analysis of an optimized hybrid energy system implementation using PV-wind turbine-diesel generator at Indonesia’s remote telecommunication base

Abstract

Nowadays, the implementation of the telecommunications industry in Indonesia should be encouraged to be more environmentally friendly, especially the source of electrification for base stations whose numbers are increasing every year. The purpose is not only to reduce CO2 emissions, but also how these efforts are made to reduce cost of electricity (CoE) so that it can improve operator’s operational cost efficiency. On this paper, author analyzed the implementation of a hybrid energy system plus (HES+) in Indonesia, which in addition to using solar panels is also optimized by adding wind turbines to areas that have proper wind speeds. Design, identifying the potential geographical location, calculation and sizing for optimized hybrid energy system is the major part of this study. Therefore, the calculation result for the CoE of base station could be as accurate as possible. It is also found that with HES+ installed, telecommunication operator has improved energy efficiency, reduced OPEX and minimized greenhouse gases with reducing 50 Ton of CO2 emission per site per year.
