In order to decarbonize the energy sector, there is a widespread consensus that the role of end-users in the energy system should change from passive consumption to active prosumption and engagement. This is of particular importance as an increasing number of technologies and business models are focusing on the end-users. These developments provide new opportunities for further technical and social innovation to smarter, flexible and integrated systems such as community energy systems (CESs). Through system integration and community engagement CESs assist in transition to a low-carbon energy system. Despite the high importance, there is limited knowledge on willingness of local citizens to participate in the local energy systems such as CESs as well as associated factors determining such willingness. Through a survey among 599 citizens in the Netherlands, this research analyses the impact of demographic, socio-economic, socio-institutional as well as environmental factors on willingness to participate in CESs. Factor and multi-variate regression analysis reveals that the environmental concern, renewables acceptance, energy independence, community trust, community resistance, education, energy related education and awareness about local energy initiatives are the most important factors in determining the citizens’ willingness to participate in CESs. Citizens should be empowered to take active role in steering the local energy initiatives.

Integrated Community Energy Systems (ICES) are an emerging local energy system focusing on the collective use of distributed energy resources (DER). These socio-technical systems (STSs) have a high potential to advance the transition towards socially inclusive, environmentally-friendly energy systems and to stimulate the local economy. While there is an analogy between energy in ICES and other common goods such as natural resources, it is not clear to what extent the existing theoretical framework for Socio-ecological Systems (SES) on the commons accounts for the specificities of common resources in ICESs and other STSs. This research explores the applicability of the SES framework to energy commons that are firmly embedded in STS with reference to the DE Ramplaan ICES in the Netherlands. The formation process and governance characteristics of this ICES are revised, further aided by stakeholder interviews. A framework and a strategic plan that can be used to design and implement an ICES are proposed.

Integrated Community Energy Systems (ICESs) are emerging as a modern development to re-organize the local energy systems allowing integration of distributed energy resources (DERs) and engagement of local communities. Although local energy initiatives such as ICESs are rapidly emerging, assessment and evaluation are still lacking on the value these systems can provide both to the local communities as well as to the whole energy system. In this paper, we present a framework to assess the value of ICESs for local communities. We apply this framework to assess the value of ICES in Spain. For a block of 10 households, investments and operations of DERs together with local exchange is simulated in DER-CAM model. For the considered community size and local conditions, ICESs are beneficial to the alternative of solely being supplied from the grid. An ICES that gets remunerated the excess energy to the grid has higher benefits than the system where energy exports are not remunerated as currently in Spain.
