Hybrid energy systems for off-grid remote telecom tower in Odisha, India

Abstract

Hybrid energy systems are increasingly being applied in areas where grid extension is considered uneconomical. Their costs can be minimised through proper equipment sizing and load matching. This paper reports the results of optimisation of solar–wind hybrid energy system for remote telecom site which is located at the coastal island (20.33°N latitude and 86.73°E longitude) in Kendrapara district of Odisha, India. The present power supply system has been optimised using HOMER (Hybrid Optimization Model for Electric Renewables) software (2.68 version) package developed by National Renewable Energy Laboratory (NREL), Colorado, USA. From the load demand and different equipment sizing, the net present cost, costs of energy and operating costs were determined and compared with only diesel generator system.
