Studies on Brandenburg’s Energy Strategy (Gaudchau et al. 2017)
How long will lignite be needed in the state of Brandenburg for a secure energy supply? With this central question in mind, RLI and HTW Berlin prepared a study on the state’s energy strategy on behalf of the Bündnis 90/Die Grünen parliamentary group in the Brandenburg state parliament.
The study is intended to support the debate on the upcoming evaluation of the Brandenburg state government’s Energy Strategy 2030. In order to be able to concretely assess the effects of the strategy as well as changes in the political and economic framework conditions with regard to lignite use, the possible energy supply of Brandenburg in 2030 was calculated using a comprehensive energy system model. In addition to heat demand and generation, the model used takes into account all types of electricity generation and the projected electricity consumption. These boundary conditions ensure that the electricity and heat demand can be covered at all times in all scenarios. In addition, the load flows for the necessary electricity transport between the regions in Brandenburg and the neighbouring regions were analysed on an hourly basis in order to identify a possible, system-relevant need for line expansion at the transmission level and storage. This was included in the assessment of the economic viability of the scenarios.
