Distributed energy generation enables grassroots people to access to clean energy and increase income to region community by participating and having ownership. In Thailand, the new community-power plant promotion scheme was launched in 2020 with the aim to raise the income equality and quality of life of local community.

❑ Biomass supply is one of the most important issues for continuous plant operation. Systematic supply chain management must be done considering availability and
logistics, seasonality, quality, and cost.

❑ BeWhere is a techno-economic engineering model for renewable energy systems optimization framework which is used for a case study of CSBPP in EEC region, Thailand as illustrated in Fig.1. It identifies the localization, size and technology of the renewable energy system that should be applied in a specific renewable energy community-based power from the region for the region.

❑ The objective is to develop decision-support tool and a linear mixed integer programming model to determine the optimal geographic locations and sizes of CSBPP using the EEC region as a case study.
