Most national, regional and municipal visions affecting the Øresund regional energy system can be boiled down to one single aspiration: The achievement of a fossil free energy system. A considerable part of this aspiration will - according to the visions - be achieved by increased wind power production. This thesis analyses the potential impacts of an increased share of wind power in the Nordic electricity system, and considers how different flexible options could counterbalance wind power in an Øresund regional context. The main objective is to highlight important trends, uncertainties and options to be considered, when making choices for a more flexible energy system in the Øresund Region. These trends and uncertainties are brought forward with inspiration from the method of Trendmapping, while the method of Backcasting has been the inspiration for seeking out combinations of flexible options, with a special focus on thermal energy storage (TES) and large-scale flexible production options. It is concluded that the increased share of wind power in combination with an inflexible combined heat and power (CHP) production to a minor extent already stimulate fluctuating power prices and outmatch thermal power production. This impact is likely to be enhanced over time and heat prices could also be affected. The more significant the differences are between high and low power prices, and the higher the heat prices are, the higher is also the potential for flexible options like TES. It is suggested to implement large-scale heat pumps in combination with the already existing tank thermal energy storages at the CHP facilities and to upscale the use of TES in order to support the flexibility of the total energy system and of renewable energy sources such as geothermal energy and solar energy.
