Dr. Johannes Wagner
has been working at EWI since 2013, first as a research associate and since 2018 as a manager. His responsibilities include the acquisition, operation and execution of applied research and consulting projects. In doing so, he facilitates the transfer of new scientific methods to practical application in order to support the decision-making process of a wide range of companies and organizations. In consulting projects for clients from the industry and public sectors, he has analyzed, for example, German and European electricity markets with a focus on distribution, digitalization and grids. He has advised, among others, the Federal Ministry of Economic Affairs and Energy as well as several industrial companies. He also contributed to the Medium-Term Coal Market Report 2015 and 2016 while working for several months at International Energy Agency in Paris. His research focus lies in the field of modelling European electricity markets. In 2018 he earned his doctorate at EWI with a thesis on “Essays on Renewable Energy in Liberalized Electricity Markets”. Before his time at EWI, Johannes Wagner studied industrial engineering at TU Darmstadt and Universidad Politécnica de Madrid.

Effects of CO2 prices on the building, transport and energy sectors
In a new short study, the EWI examined the real impact of CO2 prices on private households and the overall energy system. The analysis was carried out jointly with the Institute for Future Energy Consumer Needs and Behavior (FCN) of RWTH Aachen University on behalf of E.ON SE. The FCN estimated investment and consumption decisions of private households in the transport and building sector on the basis of empirical models. On this basis, the EWI derived feedback effects of these decisions in the energy system. Thus, the effects of a CO2 price were consistently mapped in the overall system.

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.

The energy market in 2030 and 2050 – The contribution of gas and heat infrastructure to an efficient CO2 reduction
The study examines which contribution current gas and heat infrastructure can make to an efficient minimization of greenhouse gas by 2030 and 2050 respective. Therefore the study uses a complete energy system model to quantify two possible scenarios for a greenhouse gas reduction correspondent to Germany’s 2030 and 2050 climate goals. In the “Revolution” scenario a forced electrification of final energy consumption is prescribed by the government, so that gas and heat infrastructures will more and more lose importance. In spite of the extensive electrification this is not an “all-electric” scenario, but will clearly develop in that direction. In the “Evolution” scenario there are no governmental prescriptions regarding certain technologies, so that current gas and heat infrastructure can be used continuously as long as it is economically profitable. The focus of the study lies in power and heat markets.
