Abstract. Electrical energy storage could play an important role in decarbonizing the electricity sector by offering a new, carbon-free source of operational flexibility, improving the utilization of generation assets, and facilitating the integration of variable renewable energy sources. Yet, the future cost of energy storage technologies is
The volume of electricity for that basket totalled 2.04 GWh of electric power worth PLN 1.04 billion.
