In a significant advancement for renewable energy solutions in remote areas, a recent study led by S. P. Mangaiyarkarasi from the Department of Electrical and Electronics Engineering at the University College of Engineering, Panruti, Tamil Nadu, proposes a hybrid renewable energy system tailored for primary health centres in tribal zones. This research, published in Environmental Research Communications, focuses on optimizing energy supply in regions where traditional grid expansion is impractical.
The study addresses the pressing need for reliable power in primary health centres, which are critical for providing healthcare services in underserved communities. With a peak load requirement of approximately 121.08 kW and daily energy needs of around 907.96 kWh, the research explores various configurations of hybrid renewable energy sources, particularly solar photovoltaic (PV) systems. By examining four different loading criteria—standard, boost up, step down, and complete renewable loading—along with various PV tracking arrangements, the research aims to enhance energy efficiency and reliability.
One of the standout findings is the projected annual energy production from solar PV, which could range from 318.5 to 427.65 MWh. This not only highlights the potential for solar energy in these regions but also underscores the financial viability of such systems. The study reports that the cost of energy (COE) could vary between $0.102 and $0.118 per kWh, while the net present cost (NPC) could range from $0.4047 to $0.5708 million. These figures suggest that investing in hybrid renewable systems could be an economically sound decision, especially in areas where conventional energy sources are either too costly or unavailable.
Moreover, the research delves into environmental impacts, revealing that the emissions of CO2 and CO could range from 1,700 to 4,502 kg and from 7.98 to 28.1 kg per year, respectively. By transitioning to renewable energy, these health centres could significantly reduce their carbon footprint, aligning with global sustainability goals.
The implications of this research extend beyond just energy supply; they present commercial opportunities for companies specializing in renewable energy technologies. As demand for sustainable solutions grows, there is a burgeoning market for hybrid systems that can be deployed in remote and underserved areas. The ability to provide continuous power supply not only improves healthcare delivery but also enhances the overall quality of life in these communities.
S. P. Mangaiyarkarasi emphasizes the importance of this work, stating, “The result of this work gives a conceptual and flexible design of structure to make possible the continuous power supply to the remote tribal area-based primary health centres.” This statement encapsulates the dual focus of the research: ensuring reliable energy access while fostering economic growth through innovative energy solutions.
As the energy sector continues to evolve, studies like this one pave the way for integrating renewable technologies into critical infrastructure, particularly in regions that have long been overlooked. With the insights provided by this research, stakeholders can better understand how to harness renewable resources effectively, ensuring that even the most remote communities have access to essential services.
