LUCKYN 4 1, 2, 3, 4 Electrical/ Electronic Department, Faculty of Engineering, Rivers State University Abstract- This study is focused on solving the problem of unreliable and inadequate power supply to reduce downtime, environmental pollution, operational and maintenance cost in our telecommunication industries. The aim of this study is to improved power supply to MTN Base Transceiver Station (BTS) site at T0188, Chinda Estate, Nkpolu, Oroworukwo, Port Harcourt. Using the relevant data collected from the Base Transceiver Station site, a simple algebraic and optimization methods were used to achieve the mathematical mode of the hybrid system. The results showed that the simulation executed for BTS site with a geographical location of (′′ . .2°,  ′′ . . ° ). The daily energy consumption monitored and recorded is 480 kWh/day. The peak demand for site is approximately 20kW. The economic comparison of the existing system to the proposed hybrid system configuration shows that the proposed hybrid design can be deduced to obtain a level cost of energy at N76.92/kWh with a net present cost of N175,068,300.00. The application of hybrid optimization model for energy renewable (HOLMER PRO with version 3.11.2) Software for simulation is adopted. The determination of the telecommunication industries in developing countries such as Nigeria, is to achieve its connectivity demand and for such to happen the network operators, will depend on the utility grid for a reliable and stable power supply. However, due to inadequate and unreliable power supply from the national grid, the customers expresses poor quality network service. It is recommended that the introduction of hybrid system in our telecommunication industries will led to a reduction of Operational Expenditure (OPEX). An improved power availability will reduce the incident of environmental pollution such as noise pollution, diesel spillage, etc. Thereby, achieving a greener operation.

Only about 40% of Nigerians are connected to the national electric power network (utility grid [22]. In addition, the utility grid is characterized by high unreliability index. The power supply reliability varies from 39 to 66 % with an average duration of power access between two power outages of 4.5 hours per day. At any period when grid power is available, the supply voltage fluctuates mostly between 160V and 205V [26]. The inadequacy of the utility grid has consistently led to load shedding, with adverse effects on domestic, commercial and industrial activities [23]. As a result, most entrepreneurs have resorted to using fossil-powered sources. The operation and maintenance of diesel generators accounts for about 78% of the total cost of operations of the GSM BTS sites [1]. Consequently, the use of fossil-fuel generator as an alternative source of electric power for GSM BTS sites increases the unit cost of cellular mobile services in emerging cities. Besides, the environmental consequences of harnessing and utilizing fossil fuels are assuming alarming proportions [18],[27], [24]. Power supply is one of the critical challenges confronted by telecommunications Base Transceiver Stations (BTSs) operators in deplo- ying their networks, this challenge is readily overcome in developed countries as a result of up-to-date power infrastructure. In the developing world, where a national electricity grid exists, it is always the energy solution of choice for powering Base Transceiver Stations (BTSs). Unfortunately, it is not always reliable and has limited coverage. MTN Nigeria, one of the four mobile telecoms operators in Nigeria with 4,798 base stations, spends a whopping $82.8 million
