The objective is to evaluate the technical, economic, and environmental benefits of increasing renewable energy penetration while ensuring a reliable electricity supply. Two hybrid system configurations were modeled and optimized using HOMER Pro based on the plant's energy demand and the region's solar potential. The results indicate that the optimal configuration, consisting of a 15 MW PV array, a 109.2 MWh battery energy storage system, and a natural gas turbine, provides the best overall performance. The proposed system achieves a renewable energy fraction of 24.6%, reduces annual natural gas consumption by approximately 31%, and decreases CO₂ emissions by about 1.73 million kg/year (around 31%). Battery storage improves the utilization of photovoltaic energy by storing excess generation and supplying electricity during periods of low solar irradiance. The study demonstrates that the proposed hybrid system is a reliable and sustainable solution for improving energy efficiency and reducing the environmental impact of cement plants and other energy-intensive industries.

A low-cost passive cooling system based on galvanized steel heat sinks mounted on the rear side of the PV panel was investigated using two configurations: vertical and horizontal. Experimental tests were conducted using two identical polycrystalline PV panels. One panel was equipped with heat sinks, while the other served as an uncooled reference panel. Data were collected over six days in May under different weather conditions. The results showed that the vertical configuration provided the best thermal performance, reducing panel temperature by 6 – 9.2°C due to the enhanced chimney effect and improved natural airflow. In contrast, the horizontal configuration achieved a temperature reduction of only 1– 4.4°C. Wind speed also contributed to cooling enhancement, particularly when it exceeded 2.5 m/s. The thermal improvement led to better electrical performance. The vertical configuration increased electrical efficiency by more than 2.2%, whereas the horizontal configuration achieved less than 1.5%. These findings demonstrate that galvanized steel heat sinks offer an effective, economical, and energy-free cooling solution for improving PV performance in desert environments.
