Abstract

Energy storage is essential for the successful transformation of the existing power system to one based on variable renewable energy sources. The portfolio of existing possible storage technologies at a given location within the power system is often severely constrained by a multitude of factors. Therefore, there is a need to explore the potential of thus-far neglected and uncharted territories. The prefeasibility study presented in this article addresses the theoretical potential of small-scale pumped-storage stations located in urban areas and utilizing height differences provided by built infrastructure (buildings). Geographic information system tools are applied for a selected case study (Toruń, Poland). The results revealed that a city with a population of 200 000 has a hosting capacity for small-scale pumped storage of slightly over 19 MWh or 11.3 MWh if stricter building selection criteria are considered. The article also provides a preliminary discussion of a concept of several buildings with pumped-storage upper tanks that share the same lower reservoir and estimates the role of such storage in covering city lighting needs. The discussion section is based partially on strengths-weaknesses-opportunities-threats analysis highlights the concept's main limitations and some future research directions.
