“…Despite the increasing research focused on HRES in the rural setting, few have explored its application in the context of rural healthcare facilities. Moreover, these research projects have only focused on Nigerian healthcare facilities (Babatunde, Adejoda, Babatunde, & Denwigwe, 2019;Esan et al, 2019;Olatomiwa, Blanchard, Mekhilef, & Akinyele, 2018;Oviroh & Jen, 2018;Salisu et al, 2019) and other countries in the Global South (Franco et al, 2017). These studies all conclude that shifting to HRES for the facilities will result to lower COE and CO 2 emissions.…”

This study evaluated the techno-economic viability of utilizing a hybrid renewable energy system (HRES) in a standard rural healthcare facility in the Philippines to improve energy access and resiliency. The optimal configurations were determined to satisfy the electricity demand of the RHU while reducing the cost of energy (COE) by 37-42 percent and direct CO 2 emissions by~59 percent. Both grid-connected and off-grid scenarios were considered. Results show that a solar photovoltaic panel-grid system is optimal for the grid-connected scenario while a solar photovoltaic panelgenerator-battery system is optimal for the off-grid scenario. Most of the load was found to occur during daytime (specifically from 8:00 AM to 12:00 PM) and the optimal configurations are estimated to provide at least 70 percent of the facility's electricity demand. The results of this study support the policy of encouraging the integration of HRES in rural healthcare facilities in the Philippines as a way to augment energy access and increase energy system resilience while reducing long-term costs and CO 2 emissions.

The healthcare facilities sector is an energy-intensive organization especially at a time of spreading dangerous infectious viruses, such as new Coronavirus, or what is known as COVID-19. Recently, many countries have opened several mobile field quarantine hospitals provided with the required technical equipment to prevent the COVID-19 outbreak in these countries. Unfortunately, most of these healthcare camps are lacking in the application of the necessary sustainability principles and health standards to become green healthcare facilities. Solar energy can be used for various purposes in green healthcare facilities, such as power generation and other sterilized applications. Therefore, in the present paper, a new design for the mobile, quick built, and solar-powered green healthcare camp, in safe and effective 24 hours a day services, is introduced. The proposed green healthcare camp is built using modern building technologies for rapid constructions, in which the building design is proposed to incorporate the photovoltaic power generation consideration. Photovoltaic systems are designed according to the loads required for the operation of the designed model of the green healthcare camp. Moreover, the total cost of a solar-powered green healthcare camp is estimated according to local conditions and standards in Saudi Arabia. The practical recommendations are presented with the designed photovoltaic system to attain the overcurrent and overvoltage protection. The photovoltaic designed system is proposed under the condition of ascertaining the service continuity of the photovoltaic power system during the electric faults in the photovoltaic strings. This is achieved by incorporating series diodes at the terminals of each photovoltaic string. The performance of a 50-kW PV system simulated using Matlab/Simulink is evaluated for the fault disturbance to enhance the service continuity.

“…With specific reference to Nigeria, figures show that only 45% of Nigerians have access to electricity (Fakehinde et al, 2019). This access is both epileptic and unreliable (Abdulkareem, 2016;Babatunde et al, 2019;Nnaji, 2011;Nweke et al, 2016) with incessant grid collapse. In order to enjoy electricity when needed, most Nigerian homes and businesses have resulted to the use of captive gasoline and diesel generators due to poor electricity supply from the grid.…”

Electricity supply in Nigeria is a huge problem with great economic and political consequences. After unbundling and privatization of generation and distribution companies, not much improvement has been experienced by electricity consumers; this is due to lack of investment in infrastructure. Lack of investment in infrastructure especially from private investors is caused largely by non-cost reflective tariff among other factors highlighted in this study. While many believe tariff has to be controlled such that it does not go beyond the reach of average citizens, many also believe that the average citizens can pay much more than the current tariff. The latter is evident considering the average amount spend on the use of portable gasoline generators by most homes and small enterprises both in rural and urban centers. The whole life cost method is used to show here that it costs a home or business premise that operates a portable gasoline generator for 6 h daily NGN 37,000/ month and costs NGN 157,000 to operate 20 kVA diesel generator. This shows the consumers' capacity to pay the appropriate tariff that can attract investors to the sector.
