1. Introduction
Ethiopia is well endowed with various renewable energy resources, and has a potential to generate more than 60,000 megawatts of electric power from hydro, solar, wind, and geothermal sources [1,2]. Currently, the country has approximately 4284 MW of installed generation capacity to serve a population of about 105 million people [2,3]. From the entire installed capacity, 89% of electricity is generated from hydropower [4]. Even though the country has significant electricity generating potential, it is still characterized by being one of the least electrified countries of the world with frequent and prolonged grid outages. According to a report [5], in Ethiopia, there are 8.2 electrical outages in a typical month with an average outage duration lasting 5.8 hours. All industrial, commercial and residential customers can be affected by this outage. Especially for industries, it is challenging to tolerate outages, since it causes much revenue loss within half an hour of interruption. To mitigate the negative impact of grid outage on the customer, in many locations around the globe, on-grid site was equipped with a diesel generator as a backup power source [6]. The majority of the industry zones in Ethiopia also use diesel generators as a backup [7]. However, the combustion of diesel for power generation can produce undesirable gasses, like carbon dioxide (CO2), carbon monoxide (CO) nitrogen oxides (NOx), sulfur dioxide (SO2), and particulate matter (PM) [8]. These gasses have a detrimental impact on the environment and future human life [9,10]
