In the transition to renewable energy systems, national plans are being created for several countries around the world. Concurrently, regions, municipalities and cities are planning for CO2 neutral and renewable energy systems. Both developments are necessary, which raises the question whether these two types of energy planning are coordinated. How should national plans specify local actions, and how should local plans take into account the surrounding development of the energy system? Most local plans rely on the surrounding energy systems as they need to integrate with the energy system to export excess production or import during demands with insufficient capacity. This paper suggests a methodology to analyse how well these local plans integrate with the surrounding national energy system. The methodology is applied to the two Danish examples of Copenhagen and Sønderborg. Both examples connect to the Danish 2030 scenario defined in the Coherent Energy and Environmental System Analysis study. Based on the results the study concludes that the suggested methodology is applicable for evaluating how well local and national energy systems integrate, and can potentially be used in bettering energy planning to include the benefits of local action and national coordination.
Currently, energy planning for future energy systems is divided into two branches: National planning and local municipal or city planning. This study investigated a methodology to link these two branches. The methodology enables the use of the advanced energy system analysis tool EnergyPLAN to connect a local energy system model with a model of the surrounding national energy system. The paper studied the connection between the local and national system by investigating how well the systems integrate. The level of integration was measured by investigating how well the systems can exchange excess electricity. The study divided the excess electricity into (1) integrable excess electricity and (2) nonintegrable excess electricity. Integrable excess electricity is the excess electricity that can be handled between the local and national system, while non-integrable excess electricity is the remaining excess production that has to be handled in a different manner, for instance by changing production profiles in the systems or exported to other energy systems. The study argues that by measuring the level of integration it enables researchers and planners to identify how well a local and national energy plan can work together. As such, the methodology can help towards linking local and national energy planning.
