Assessment of small hydroelectric power plants in the Syunik region of the republic of Armenia

The focus of this study is the performance of small hydroelectric power plants (SHPPs) in Armenia’s Syunik region, especially the Tatev SHPP along the Vorotan River. This study is undertaken from a multifaceted approach involving hydropower simulation models and environmental assessment using the Leopold matrix. Most impacts are ecological, and protecting the river flow and aquatic habitats is essential, especially considering the predicted decrease in water discharge due to climate change by 15-30%. However, the good news is that these small hydro projects result in a carbon footprint reduction of about 3,500 tons of CO₂ emissions and create employment opportunities for the surrounding communities. The entire data collection has brought out that the small- sized hydroelectric projects for which the planning and management were carried out in detail are instrumental/will be instrumental in the transition of the Armenian energy system to cleaner and more absolutely sustainable energy.
