Powering Albania's Future: Feasibility Study for the 1200 MW Moglice Hydro Plant

GOPA Tech undertook a comprehensive power system study for the PS Moglice Extension in Albania, focusing on the feasibility of a 1200 MW pump storage hydro plant. This pivotal study encompasses several critical aspects, including transmission grid modeling, grid reinforcement planning, and dynamic stability analysis. The primary objective is to ensure the stable integration and operation of this substantial pumped hydro power storage facility within Albania's existing power network.

Through meticulous grid modeling, the project aims to identify potential bottlenecks that could impede future grid performance. Additionally, the study seeks to pinpoint optimal connection points to facilitate seamless integration of the hydro plant into the transmission network. By planning necessary grid reinforcements and conducting dynamic stability analyses, the project strives to propose effective mitigation measures that will enhance the overall stability and reliability of the power system.

This initiative is poised to significantly bolster Albania's energy infrastructure, providing a robust and sustainable solution to meet the growing energy demands. The successful implementation of the PS Moglice Extension will not only contribute to energy security but also support Albania's commitment to renewable energy and environmental sustainability.

Main Activities

• The main objective of the study was to determine potential sizes (MW) of a large new pump storage hydro power plant (1200 MV +/- 35%).
• The study included different locations for point of connection to the existing trans-mission grid. It is assumed to connect the power plants to the existing 400 kV grid. The study identified future bottlenecks in the Albanian transmission system and potential mitigation measures to ensure stable grid operation
