Abstract
More and more households are installing residential electricity storage systems to increase the self-consumption of electricity they produced. Some governments have accelerated this development through specific financial support schemes to offset the costs, which still remain high. Compared to the use of single-household systems, the sharing of mid-scale electricity storage systems in neighborhoods could reduce the Levelized Costs of Storage (LCOS). However, a model for the shared usage of storage by multiple households has yet to emerge. We investigated eight demonstration projects in Germany and Western Australia with capacities between 100 and 1100â¯kWâ¯h with respect to potential business models and barriers in a cross-case study based on document analyses and expert interviews. We found that models relying on the transmission of electricity from individual rooftop photovoltaics to a shared storage system through the public grid are facing significant regulatory barriers. Removing these policy barriers would enable a more efficient use of electricity storage systems. By contrast, projects relying on a less regulated microgrid managed by the administration or strata entities of multi-household developments already seem promising under the current regulatory framework.
