  Electricity distribution networks that contain large photovoltaic solar
systems can experience power flows between customers. These may create both
technical and socio-economic challenges. This paper establishes how these
challenges can be addressed through the combined deployment of Community-scale
Energy Storage (CES) and local network tariffs. Our study simulates the
operation of a CES under a range of local network tariff models, using current
Australian electricity prices and current network prices as a reference. We
assess the financial outcomes for solar and non-solar owning customers and the
distribution network operator. We find that tariff settings exist that create
mutual benefits for all stakeholders. Such tariffs all apply a discount of
greater than 50\% to energy flows within the local network, relative to regular
distribution network tariffs. The policy implication of these findings is that
the, historically contentious, issue of network tariff reform in the presence
of local solar power generation can be resolved with a mutually beneficial
arrangement of local network tariffs and CES. Furthermore, the challenge of
setting appropriate tariffs is eased through clear and intuitive conditions on
local network tariff pricing.
