Techno-economic Analysis of Hybrid Renewable Energy System for Healthcare Centre in Northwest Bangladesh

Abstract

Assessments for the techno-economic viability of the hybrid renewable energy system have been stimulated due to the frequent price hike and falls of fossil fuels, the derivatives generated during the burning of the fuels that are emitted into the environment, and the very high installation cost of the present day’s conventional photovoltaic energy system. This paper reports on the techno-economic performance assessments of a hybrid renewable energy system for a rural healthcare center in Bangladesh. These healthcare centers are essential for the residents of rural areas in Bangladesh. In this regard, a microgrid solar hybrid photovoltaic system has been designed to power a healthcare center in Gangachara Upazila (sub-district), Rangpur district, a northwest region in Bangladesh. The rooftop PV system comprises 400 Wp solar panels, a 25 kW bi-directional inverter, a 28 kW generator, connecting wires, a mounting system, and related accessories. In this assessment, state-of-the-art PV design software, HOMER Powering Health Tool, has been utilized for estimating the load requirements and for techno-economic and environmental evaluation of the microgrid system. The load analysis revealed that a 32 kW grid–connected solar PV system was required for the selected healthcare and the estimated net present cost was US$ 33,818, with a levelized cost of energy was US$ 0.022.

“…The depletion of energy sources and consumption of fossil fuels, natural gas, coal, etc., have a negative impact on our society and environment. [1][2][3][4][5] Therefore, developing alternative energy resources and sustainable energy sources with few economic and environmental concerns are the center of research worldwide. [6][7][8] A solar cell is one of the most potential renewable and sustainable energy sources to attain the increasing energy demand and mitigate global warming.…”

The Obstruction and Advancement in Sustainable Energy Sector to Achieve SDG in Bangladesh

“…In these articles, researchers discussed important aspects of developing countries' goals and achievements in the energy sector in the light of economic, political, and social realities, and pointed out inadequate funding and lack of proper policymaking as major obstacles in some developing countries. In terms of renewable energy, what role renewable energy can play in building sustainable rural infrastructure in developing countries, as well as technical, infrastructural, and economic barriers [44], have come up in all these articles. Painuly (2001) has identified some of the major obstacles in some developing countries' ability to achieve sustainable energy, such as market inequality, economic viability, and technological and institutional problems [45].…”
