The energy generation sectors in many countries around the world are experiencing a great transition period, moving away from fossil-based electricity to cleaner energy sources. Due to regulated emission limits and the integration of renewable energy sources, coal-fired power plants are heavily affected in terms of reduced operating hours and material life-time, lower efficiencies, higher operational expenses, and earlier retirement. By combining both literature review and analyzing real-time operational data from coal-fired power plants, this paper aims to provide an overview on: – The commercial and technological impacts of the energy transition in Europe (with a focus on Germany) – CO2 emission during stationary operations at two lignite-fired power plants. – CO2 emission during Start-up processes at a hard coal-fired power plant. – Potentials for reducing emission as well as lowering operational expenses.
