Martin Hintermayer

is Research Associate at EWI since 2016 and doctoral candidate at the University of Cologne. In consulting projects for clients from the industry and public sectors, he has analyzed, e.g., the contribution of gas and heat infrastructure to an efficient CO2 abatement and the contribution of a gas storage L-gas supply security. He has advised, among others, the German Energy Agency (dena) and the EU Commission. His research focus lies in the field emissions trading and power markets. Martin Hintermayer completed his studies in Mathematics and Economics (concentration optimization and certificate trading) at Georg-August-Universität Göttingen (Germany).

Economic assessment of the market development model

To extend the current marketing possibilities for electricity from renewable energy sources, Bundesverband Windenergie (BWE) and ARGE Netz propose a market development model. This proposal of changing the Renewable Energy Sources Act (EEG) is supposed to allow a direct retail of renewable electricity from the plant operator to final consumers and at the same time to ensure the proof of the simultaneousness of generation and consumability. ewi ER&S analyses the economic effects of the market development model.
For final consumers, the model creates a possibility to show their preference – and thereby their willingness to pay – for consumable renewable power and to purchase it. This allows the plant operators a better marketing option of their consumable renewable power. If production and consumption happen spatially close to each other, this can additionally relieve the grids. The EEG account will not receive additional financial burdens, even reliefs are possible.

dena-Leitstudie Integrierte Energiewende (dena Study on Integrated Energy Transition)

The dena-Leitstudie Integrierte Energiewende develops and compares transformation pathes for the energy system in Germany with the objective to attain the climate-political goals by 2050. It pursues an innovative cross-sector scenario approach. At the same time, it is based on the branch knowledge of more than 60 partners from all relevant sectors and on the continuuos exchange with important actors from politics, society and science. The objective is to give impulses for designing the energy system by 2050. ewi ER&S is the main scientific advisor to the study. The central results of the study say that Germany will be able to attain its goals to reduce greenhouse gas emissions by 80 as well as by 95 % up to the year 2050 if the strains in all sectors are increased. Therefore, the roll-out and system integration of renewable energy sources must be forced, the end energy consumption has to be reduced by extensive energy efficiency efforts, and synthetic regenerative energy sources must be used on a big scale. A broad mix of technologies and energy sources makes the transformation of the energy system more cost-efficient than a fortified use of electricity-based applications.

Central European Gas Market Congestion Analysis

The study assesses whether the Nord Stream 2 pipeline contributes to a division of European gas markets. It demonstrates that the Nord Stream 2 pipeline cannot be used for market separation, under conditions of existing pipeline capacity and local gas consumption. This is due to the fact that in the European internal market, according to the EU’s own market rules, the importers and thus also the consumers are protected against such behaviour. Even if under increased gas demand in East Europe, such a strategy for splitting the market would be neither successful nor effective.

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.

Gebäudestudie – Szenarien für eine marktwirtschaftliche Klima- und Ressourcenschutzpolitik 2050 im Gebäudesektor

The Buildings Study (Gebäudestudie), initiated by the members of the Allianz für Gebäude-Energie-Effizienz (geea), provides an economic analysis of the buildings sector. It investigates how the transformation of the buildings sector can be accomplished by an interplay of building shell, installation technology and a changed energy production, to reach an attainment of reducing greenhouse gases by 80% and by 95%. The study was created in the context of the dena-Leitstudie Integrierte Energiewende (Integrated Energy Transition). ewi ER&S is the main economic reviewer of the study, cooperating with FIW and ITG as technological reviewers.

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.
