Geothermal power plant operating conditions and efficiency are heavily influenced by the quality of the produced geothermal fluid, which is directly affected by changes in geothermal well performance and reservoir dynamics. The Alaşehir geothermal field, one of the most active fields in Türkiye, is operated by various geothermal developers. This study highlights the challenges encountered during 10 years of operation at a combined double-flash and binary geothermal power plant, with a focus on resource and power plant management. Solutions implemented include enhanced resource management strategies and operational improvements such as ESP installations, gas lifting, acidizing, booster pumps, and equipment upgrades. Modifications and adaptations were applied to critical components such as pumps, fans, heat exchangers, turbines, and other equipment in both the flashing and binary systems to maintain efficient and reliable operations.
