Renewable energy integration in healthcare systems: A case study of a hospital in Azad Jammu and Kashmir

Abstract

AbstractRenewable energy sources have gained widespread attention due to their abundance and cost‐effectiveness. In particular, healthcare systems and hospitals are increasingly seeking clean and renewable energy solutions to reduce energy costs, price volatility, and protect community health. However, proper load estimation and techno‐economic analysis are crucial to ensure the optimal performance and reliable power supply of renewable energy systems. This study focuses on conducting a case study on load estimation and techno‐economic analysis for a hospital located in a remote area of Azad Jammu and Kashmir, Pakistan. Through this analysis, the study aims to determine the feasibility of implementing a renewable energy system at the hospital and assess the potential benefits in terms of energy production, cost savings, and environmental impact. Two different clean energy management softwares, HOMER PRO and RETScreen Expert, are utilized to compare the proposed hybrid (PV/Wind/Battery/Convertor/Grid) system with the existing system in terms of cost minimization, optimal system configuration, and environmental effects. The results demonstrate that the proposed hybrid system is more efficient, stable, cost‐effective, and a environmentally friendly option. Moreover, the annualized energy production, consumption, and grid load reduction are also calculated. The findings of both software programs are compared for validation of the proposed optimal system. The techno‐economic analysis of the proposed system can serve as a useful guideline for other commercial facilities in the region to utilize solar and wind energy.
