diffusion will seed new ideas among stakeholders and enable industry development, such as implementing new practices or reducing barriers to mainstreaming DER. These new practices, in turn, can lead to wider societal impacts, such as reduced greenhouse gas emissions. Figure S-2 provides additional detail on the impact framework and applies it specifically to this research topic. The figure also identifies indicators that can be evaluated at each stage of the chain. Figure S-2 Impact framework for Theme N2: LV Network Visibility and Optimising Hosting Capacity
S4: Economic Potential Analysis This section provides a preliminary analysis of the value of the potential impacts of research into optimising hosting capacity for DER. This is a broad and complex question, so we have deliberately sought to keep the scope narrow. The analysis leverages existing models and datasets to identify the costs and benefits across different scenarios. A definitive cost-benefit analysis is not possible and outside the scope of this report; we seek rather to provide an indicative range, compare that range with other estimates and understand which drivers and uncertainties are most impactful. Rooftop solar PV is the most widespread and affordable DER technology and its capacity continues to grow strongly. Given the existing and continued large scale deployment of rooftop solar, it is a key focus of the analysis. We have also assessed vehicle-to-grid batteries as the next highest value opportunity for value to be gained from improved hosting capacity.
