<p>This paper illustrates the implementation of a hybrid renewable system in a heat power station, considering the interconnections among energy, water, and environmental impacts, given that the power generation sector accounts for a substantial share of global fuel and water usage and CO₂ emissions. Using the PVsyst tool, the solar energy system setup and carbon balance assessment were conducted in 2023 for the power station’s operation. The effects of lower carbon emissions on the ecosystem have been examined using the ReCipe environmental model. The study’s findings show that 1259.46 tons of CO₂ may be averted yearly by using solar energy to replace 2% of the fossil fuel power station’s nominal capacity. This amount is equivalent to 373.55 tons of crude oil and 362.16 cubic meters of fossil fuel reserves. The outputs also demonstrated that the hybrid cycle’s design results in a significant decline in water usage of 3569 cubic meters, which might potentially refill underground water supplies, besides to conserving natural resources. The nexus approach framework supports managing power supply by alternating resources and utilizing water and thermal recovery technologies. It also supports putting in place energy demand management policies that focus on energy conservation and environmental sustainability. This is because we need to protect energy and water resources and lower carbon emissions in the power generation sector.</p>
