###### 1 Introduction  
The Merredin region of Western Australia holds strategic importance due to its significant mining operations, which contribute to regional employment and economic development. However, the high energy demands of mining sectors present a major challenge requiring a stable and continuous power supply in remote areas where grid connectivity can become limited and unreliable [1, 2]. Hydrogen-based hybrid energy system was proposed in [3] considering Pakistan's Bannu district. The applied method was able to decrease the total net present cost (NPC) and cost of energy (COE) by 21.7% and 19.8%, correspondingly. It further recommended to study on the global applicability. In [4], hydrogen-based solar-powered energy system was studied for Balochistan, Pakistan region. The implemented optimal framework reduced COE and NPC by 26.9% and 3.0% respectively that recommended to study on other rural areas for future research. The technical and financial feasibility of PV-wind-hydrogen system installed in Cooma, Australia was analyzed in [5]. The authors concluded that around 9.2% efficiency can be found from the hybrid system whereas hydrogen subsystem was expensive compared to other sources. It further recommended to investigated on other Australia regions. Traditionally, Western Australia's mining sectors have relied on grid electricity systems for large-scale operations, where this has considerable limitations. Firstly, due to voltage fluctuations, supply shortages, and network failures, grid power in remote areas such as Merredin can be inconsistent, leading to operational disruptions. Secondly, the high cost of purchasing electricity from the grid places a significant financial burden on mining companies, particularly given the energy-intensive nature of their activities [6]. Moreover, reliance on conventional energy sources, such as fossil fuels, contributes to substantial carbon emissions, which conflict with growing environmental and sustainability concerns in the industry. The Merredin WA Solar Project aims to address these challenges by providing a clean, reliable, and cost-effective alternative energy sources for the region. At the core of this initiative is the development of a solar photovoltaic (PV) system designed to harness the region's abundant solar energy resources [6]. Merredin receives exceptionally high leveled solar radiation, making it an ideal location for large-scale solar power generation. With this, the study seeks to integrate advanced battery storage technology to ensure continuous power availability in the region, including during nighttime hours and periods of low sunlight. This hybrid system enhances energy reliability and minimizes dependence on the conventional power grid [7; 8]. Since energy security is a key operation in mining industries, the Merredin WA Solar Project can reduce the mining sector's vulnerability to grid power disruptions [9; 10]. This self-sufficiency of energy also provides long-term economic benefits by insulating mining companies from fluctuations in electricity prices and potential cost increases associated with fossil fuel-based power generation [11; 12]. However, using data pre-processing subsequent to data collection to obtain the optimal solutions regarding cost savings remains a challenging objective. The collected data from remote and harsh environments indicate that mining sectors are susceptible to system instability that may result in blackouts. Therefore, recent studies in mining energy systems [13; 14; 15; 16] highlighted data analytics of mining industries and suggested pre-processing to achieve a global optimization result. The authors recommended to apply machine learning algorithms for data processing and obtain the optimal solution in mining industry. Similarly for mining operations, the Merredin WA mining sector can serve as a model for other industries and regions, demonstrating the feasibility and advantages of renewable energy solutions for energy-intensive operations [17; 18].
