Distributed generation of electricity and residential consumption have a large, but so far unexploited, potential for flexibility. New business model for local flexibility are currently explored by utility companies as well as start-ups. Up to date, we know little on the consumer acceptance of local flexibility provision. We investigate the consumer participation for business models for decentralized flexibility, by adapting the simulation platform TREES specifically to this case study. Driver and barriers for the diffusion of local flexibility business models are integrated to develop a platform for business strategy testing. We analyze the long-term value creation potential with local flexibility for the concrete application setting of the project partner Romande Energie. In particular, we model, analyze and evaluate three business cases for decentralized flexibility: battery swarms, district batteries and multi-energy flexibility. Results will reveal insights on likely customer participation rates, promising strategies for valorizing flexibility and suitable tariff designs to compensate the flexible prosumers.
