Sammendrag
This document is a master thesis that attempts to assess the plan of pumping water from the nearby lakes of Djupåvatnet (435 m), Buvatnet (465 m), and Strandvatnet (5 m above sea level) up to the lake of Niingensvatnet (510-494 m above sea level) to store energy for later use and increase energy generation. The assessment process proved that pumping water from Strandvatnet and Djupåvatnet to Niingensvatnet is not financially feasible, while the case of Buvatnet-Niingensvatnet pumped storage is cost-efficient and has many benefits in terms of increasing stability and profitability.
