Sharing distributed energy resources in apartment buildings: the winner takes it all?

Solar generation is one of the key technologies in decarbonizing and decentralizing the energy system. While solar PV on single-family houses is a well-established and integrated solution, there have been relatively few such installations on multi-unit apartment buildings so far. Also, with the rapid urbanization, cities – mostly with a high share of apartment buildings – are becoming the largest energy consumers globally. Hence, to address the energy-climate challenge innovative solutions have to be developed to make better use of distributed energy resources (DERs) in urban locations.

By comparing apartment buildings with single-family houses, multiple differences can be identified: Firstly, a higher number of consumers (owners/tenants) are involved; secondly, consumers have to agree on an energy allocation method, because they share a common energy resource (e.g., solar PV, possibly combined with energy storage). Thirdly, individual consumer objectives have to be taken into account with the possibility of conflicting objectives between different parties. Finally, interactions with the surrounding system (local power grid, utility, electricity market) must be considered.

BestRES recommendations for policy makers

The BestRES project developed 13 Business Models to facilitate the integration of renewable energy sources into the energy market by aggregating distributed generation and combining it with demand side management and energy storage. However, these Business Models encounter various barriers on their way, be it of economic, technical or legal nature. The paper “The impact […]
