Introduction of power-to-gas in Germany
The discussion paper analyses the integration of power-to-gas plants into the energy and regulatory framework in Germany. For this purpose, four power purchase options of the plants are compared and their influence on the power purchase path, the purchase costs, the green power characteristics, and the competitiveness of the plant is examined. It is shown that business models based on the power purchase options have fundamental peculiarities, as the plants are operated either in a regulated or in a market environment and thus require different investment incentives.

Development of the momentary reserve and estimation of the need for Fast Frequency Response in the European network system
Together with ef.Ruhr, EWI investigated the development of frequency stability in Germany on behalf of Siemens AG. With the help of the European electricity market model DIMENSION, the power plant parks of two scenarios were optimized for the year 2040. The first scenario exclusively depicts the German coal phase-out, while the second scenario additionally assumes that the European countries with a high proportion of conventional power generation will make a change towards renewable energies. As indicators for the frequency stability of the resulting systems, ef.Ruhr uses a point model to determine the frequency gradients, grid start-up time constants and dynamic frequency minima.
The analyses carried out show that there is a need for action in order to be able to guarantee the frequency stability of the energy supply system in the year 2040 without restrictions. The decrease of the instantaneous reserve due to decreasing energy from conventional power plants results in the shortfall of the permissible frequency minima as well as in a critical increase of the frequency gradients, which can cause critical system states in each case. An increase in the instantaneous reserve or an acceleration of the primary control power can guarantee frequency stability.

Impulse for the current climate policy debate: Assessments based on the dena lead study Integrated Energy Transition
Together with the German Energy Agency (dena), EWI has examined developments in power generation and the end-consumer sectors of buildings, industry and transport since the publication of the “dena Lead Study Integrated Energy Transition “. The analysis compares the changes between 2015, the base year of the dena study Integrated Energy Transition, and today with the transformation paths and model results in 2030. The EWI figures show: The efficiency improvements in the sectors assumed in the dena study cannot be observed. Regarding the expansion of renewable energies, particularly in wind energy, a significant decline is expected. Various indicators show that there are currently no incentives for a rapid and cross-sectoral reduction of greenhouse gas emissions. Based on the analysis of the key figures by the EWI, dena develops comprehensive recommendations for action so that Germany can still achieve the its climate target in 2030.
