Abstract
Primary Healthcare Centres (PHCs) remain the populations' first point of contact when seeking medical help. Women and children, whose health status decides the fate of the country, are the predominant users of primary healthcare centres which means they (the PHCs') must function as high quality health providers. Karshi Primary Healthcare Centre (KPHC) is one of the health facility that need reliable electricity to improve their healthcare delivery. Due to unreliable power supply, they rely on a diesel powered solution as a primary source of power supply. This negatively impacts patients and the environment, and has been a burden on their operational budgets. Change in energy system is the solution to this unreliable, costly, and unsecure power supply in Karshi, and its objective is to improve and enhance the quality of healthcare delivery services. The assumption is that with better energy source, there will be better healthcare services. A solar powered system with battery storage was proposed as the solution and the simulation results demonstrate that except for the initial cost of investment, the solar PV generator performs better than the diesel generator, in terms of the life cycle costs and the cost per unit energy. The life cycle cost and the cost of energy show a decrease of 75% each. The environmental analysis implies that the solar PV energy system has the potential to avoid the 9371 kg of carbon dioxide if the system is implemented in the future at KPHC. The proposed powered system will supply electricity for the laboratory equipment (centrifuges, microscopes, blood chemical analyzer, hematology analyzer, CD4 machine), vaccine-refrigeration, general purpose refrigerator, computer and telecommunications, while being able to cater to a greater number of patients than in the past.
Highlights
Operators of health facilities in developing nations across the world are faced with problem of unreliable power supply which has hindered its functionality, limiting the effective delivery of quality healthcare services to the populace by the main users of services [1]
After the energy efficiency model which resulted in the generation of Tables 5 and 6 from Table 3, we identified the solar resources of the location using a geographic information system (GIS) mapping as shown in Figure 1, calculate the PV system sizing, and compare the costs and emissions of stand-alone power supply options using HOMER
The results demonstrate that except for the initial cost of investment, the solar PV generator performs better than the diesel generator, in terms of the life cycle costs and the cost per unit energy
Summary
Operators of health facilities in developing nations across the world are faced with problem of unreliable power supply which has hindered its functionality, limiting the effective delivery of quality healthcare services to the populace by the main users of services (mothers and children) [1]. Between and 2016, Nigeria generated between 3000 and MW (megawatts) of electricity, far less than the estimated demand of 10 000–12 000 MW [7] This has resulted in frequent and unpredictable load shedding which has affected many communities’ healthcare centres, forcing them to rely on kerosene lantern as source of lighting and diesel generators as their primary source of electricity. The power situation is so unreliable that the generator runs on morning and afternoon and that consumes a lot of diesel, and negatively impacts patients and the environment. This is where energy intervention (change in energy system) is needed, and will be demonstrated here as outlined by the author’s recent research work [9]. The theory of change here is that reliable energy provision to the health centre will lead to better health outcomes in the population based on the fact that the quality of health services provided can be improved with access to electricity
