Effects of the coal phase-out act for lignite-fired power generation in the Rhenish mining area

The study examined the effects of the coal phase-out act on lignite-based power generation in the Rhenish mining area. The study focuses on an estimation of the lignite demand for electricity and heat supply of the Niederaussem, Neurath and Weisweiler power plants in the period 2021 to 2038. In addition, the effects of the planned coal phase-out on the development of national generation capacities, electricity generation, import balance, greenhouse gas emissions and wholesale electricity prices are analyzed.

Effects of a tightening of European climate targets on the German electricity market
The background to this analysis is that the EU is tightening its climate target for the year 2030: instead of the previously planned reduction of 40 percent, a minus of 55 percent is to be achieved for the year 2030 compared to the year 1990. The analysis "Impact of a Tightening of European Climate Targets on the German Electricity Market" shows the effects of the tightening of climate targets on the power plant fleet, electricity generation, wholesale electricity prices and the sectoral climate target of the energy industry in Germany in 2030.
