The role of energy storage technologies in the context of the Swiss energy transition (SwissStore)

The role of energy storage is subject to intense debates at the national and international level, reflecting a lack of consensus about the techno-economic potential and respective merits of the various energy storage technologies. This is largely due to the wide spectrum of possible applications, evolving technology and unclear market conditions. In the context of the SwissStore project we studied energy storage in different contexts and from different perspectives, i.e.
• in households, in combination with photovoltaic panels (coupled with batteries and thermal storage), taking the perspective of the private investor
• in all buildings (all sectors, also with PV), with a focus on increased short-term flexibility, thereby also considering other strategies next to storage (e.g. demand-side response) and taking the perspective of the social planner.
In both cases, optimisation frameworks were developed for Switzerland and different scenarios were studied for the next decades.
