CO2 Pricing in the Building Sector and Necessary Additional Instruments
CO2 pricing provides incentives for investments in climate-friendly heating technologies and energy-efficient renovation. But a tax on greenhouse gases or an emission trading system alone will hardly be enough to make them economically attractive. Additional policy instruments are needed to do justice to the special features of the building sector. These are the key findings of a study conducted jointly by the Institute of Energy Economics at the University of Cologne (EWI) and the Institute for Public Economics at the University of Cologne (FiFo) on behalf of the Zentraler Immobilien Ausschuss e.V. (German Property Federation) (ZIA).

Effects of the phase-out of coal-fired power generation by 2038 on the electricity market, CO2 emissions and selected industries
At the end of January, the Coal Commission presented its final report. The EWI examined the effects of that report on behalf of MWIDE NRW (Ministry of Economic Affairs, Innovation, Digitalisation and Energy of North Rhine-Westphalia). The European electricity market model DIMENSION+ was used to compare the developments of a reference scenario with those of the phase-out scenario. Based on this analysis and further investigation, an international comparison of electricity prices for selected power-intensive industries was made. In the scenario analysis, the EWI reaches the following key results: The recommended exit path makes it possible to achieve the 2030 climate target for the energy sector even with a moderate increase in demand for electricity. Whereas this target is clearly missed in the reference scenario. However, in the coal phase-out scenario, an ambitious expansion of the number of peak-load power plants by 2025 is necessary in order to ensure security of supply. Electricity prices will rise significantly in both scenarios due to rising prices for CO2 certificates. For the German industrial companies considered, electricity prices are rising relatively strongly in both scenarios compared with foreign prices. Aid payments to compensate indirect CO2 costs (so-called electricity price compensation) can reduce the increase in electricity prices.

The underrated long-term relevance of gas in the decarbonizing German energy space
‘ewi ER&S’ and ‘The Gas Value Chain Company’ have extracted the considerations and arguments addressing the long-term relevance of gas in the decarbonizing German energy space in various studies, with strong focus on the ‘dena- Leitstudie’ “Integrierte Energiewende”. They compare a scenario labelled “Electrons” - implying a high degree of electrification and lower use of gas – with a scenario labelled “Molecules”, the latter implying a higher degree of direct gas use in all sectors.

Nord Stream 2 and its effects on European wholesale power prices
On behalf of Nord Stream 2, ewi ER&S analyzed the effects of the Nord Stream 2 pipeline on European wholesale power prices. The study shows that European electricity prices will be between 2.2 to 4.3 €/MWh lower (a 5% to 8% reduction) in a Low LNG price scenario, and 6.5 to 10.7 €/MWh lower in a High LNG price scenario (a 12% to 16% reduction). These lower prices result in a benefit to European consumers of €7bn to €14bn per year in the Low LNG price scenario and €21bn to €35bn per year in the High LNG price scenario.

Study comparison sector coupling
In April 2018 ewi ER&S published the study "Kosteneffiziente Umsetzung der Sektorenkopplung" on behalf of the Ministry of Economics, Innovation, Digitisation and Energy of North Rhine-Westphalia. In June 2018, the "dena-Leitstudie Integrierte Energiewende" was published with ewi ER&S as the principal scientific assessor. Both studies analyse cross-sector strategies for achieving climate targets in the medium and long term. Within the framework of the "Studienvergleich Sektorenkopplung ", similarities and differences in the design of the study are pointed out transparently and the differences in the results are presented in detail.

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.

Cost-efficient realization of sector coupling
The study examines options for a medium-term and long-term attainment of German goals for the reduction of greenhouse gases by 2050. The focus lies on finding cost-optimal development pathes in the energy consumption sectors of buildings, transportation, industry and in the energy sector. The study finds that a technology-open approach is to be preferred to an extensive electrification of the consumption sectors. In addition, the German climate goals are classified into the European context, incentive structures are analyzed from stakeholders' pespectives, and recommendations for a further development of legal frame conditions are yielded. The study was commissioned by the Ministry of Economy, Innovation, Digitalization and Energy of the state of North Rhine-Westphalia (MWIDE). The ef.Ruhr GmbH is the cooperation partner for examining the implications on the electricity networks.[Study (in German, short version)] [Study (in German, long version)]

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.

Identifying Key Assumptions for Evaluating Nord Stream 2’s Impact on the European Natural Gas Market
Compared to what ewi ER&S found in the study on "Impacts of Nord Stream 2 on the EU natural gas market", the results of Regional Centre for Energy Policy Research (REKK) of Hungary yield different results on the price effects. This study shows that different assumptions about LNG import prices, Ukrainian transit capacities and the contracts of using them, and intra-EU infrastructure expansions are crucial to explain the differences between the ewi ER&S results and those of REKK.

Impacts of Nord Stream 2 on the EU natural gas market
This study focuses on the impacts of the offshore pipeline Nord Stream 2 on European Union (EU) natural gas markets (gas flows and gas prices). Since the impact of Nord Stream 2 crucially depends on the competition between Russian gas and global LNG markets, a combination of the global gas market model COLUMBUS and the European gas infrastructure model TIGER is applied in the analysis. The study finds a price decreasing effect of Nord Stream 2 in the EU-28 overall as well as in each member state individually due to reduced LNG imports if Nord Stream 2 is available compared to a case in which it is not available.

Disruptive Potential in the German Electricity System – an Economic Perspective on Blockchain
The hype around blockchain provided some rather discouraging scenarios for companies in the German electricity system. Our new analysis recently shows that blockchain currently has no disruptive potential for peer-to-peer power transactions. The study illustrates that while platforms (e.g., based on blockchain technology) for peer-to-peer transactions do not face organizational or regulatory barriers, levies, taxes and surcharges on final consumer power consumption burden the disruptive potential of the technology and hamper deployment. Public blockchain-based platforms will come with additional costs for underlying distributed mechanisms.

Future European Gas Transmission Bottlenecks in Differing Supply and Demand Scenarios
As previous studies by ewi ER&S and the Oxford Institute for Energy Studies (OIES) showed, there are bottlenecks in the European gas transmission grid. Especially between Germany and Italy, Germany and Austria as well as between the two French market areas, bottlenecks exist. This study focuses on the question if those bottlenecks persist in future. Therefore, two scenarios of OIES with high and low Asian gas demand which influences the European LNG supply are simulated in the European gas infrastructure model TIGER. Infrastructure extensions that are needed to realize the assumptions concerning demand and supply are modelled. The results indicate that especially in the scenario with high Asian demand (low LNG imports to Europe) bottlenecks persist in the European gas infrastructure in 2030.

Black Swans (Risks) of the “Energiewende”
The “Energiewende“ is of great importance for the energy supply as well as the economic development in Germany. The study at hand supports a political risk management focusing on unexpected or unlikely events (so-called “Black Swans”) and their effects in energy policy and macroeconomy as a whole. Building on this, it has the goal to analyse which (political) precautionary and reaction measures exist. As such, the main task of this study is to identify the principal risks arising from and to the “Energiewende”, in particular the deployment of renewable energies, and to analyse their effects.

Economic Impacts of a German Coal Phase-Out on the Power Markets in Germany and the EU
With the study „Economic Impacts of a German Coal Phase-Out on the Power Markets in Germany and the EU“, ewi ER&S takes up a proposal made by the German think tank Agora Energiewende in January 2016 concerning a coal phase-out in Germany. The proposal suggests a combination of two policy measures for the power sector. First, it encourages an early decommissioning of the German coal-fired power plants up to 2040 and, secondly, a retirement of emission allowances from the European emissions trading system in the amount of the mitigated CO2 emissions resulting from the coal phase-out. Based on ewi’s power market model DIMENSION, the study investigates the additional costs and distributional effects of this double-measure for the German and European power markets. The coal phase-out is assessed by economic theory and its projected costs are compared to the amount of CO2 abated.

Electricity cost in the non-ferrous metal industry – A sensitivity analysis
On behalf of the WirtschaftsVereinigung Metalle e.V., EWI analysed the effects of an increase in electricity prices on the gross value added of exemplary companies in the non-ferrous metal industry. In 2017, the electricity prices of companies in the non-ferrous metal industry fluctuated between 3.6 ct/kWh for an aluminium electrolysis plant and 14.0 ct/kWh for a small copper rolling mill. The large differences are mainly due to the deviating regulatory relief schemes. Compared to other branches of the manufacturing industry, the electricity cost intensity is highest in the metal industry with an average of 14.5 %, an electricity price increase therefore has comparatively strong effects. An increase in electricity prices by 1.0 ct/kWh would reduce the gross value added of the metal industry by 439 million Euro (2.3 %), processes with high electricity-cost intensity such as aluminium electrolysis would be particularly affected strongly.

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.

Regional market potentials of cross-sectoral energy services
In this study, we analyze the market potentials of cross-sectoral energy services, i.e., power supply for tenants, battery storage at household level and e-mobility in Germany. We especially focus on the differences between regions. As a start, we describe the general opportunities for companies regarding energy services. Specific models and use cases for the three energy services are depicted in further detail. We then proceed to analyze the market potential in Germany over the next years. The regional analysis is (partially) broken down to postal code level. The results show that for every energy service the distribution of the regional potential is quite different. This is due to several (regionally differing) factors, e.g., density of population, car ownership or photovoltaic installations. Depending on a company’s regional activity this has different strategic implications regarding their portfolio of energy services.

Short study: Flexibility potential of households for the network-related reduction of demand peaks
In future, increased use of heat pumps and electric cars in the building and transport sectors could create new requirements for network expansion and operation, especially in the low-voltage networks. The increased use of heat pumps and electric cars has an impact on the quantity of electricity demanded and on the temporal structure of electricity demand. Against this backdrop, the question arises as to which flexibility potentials could be used cost-effectively in households in the future. In the context of this study, the flexibility potential of different household types is analysed. The focus here is on the costs of flexibility in time windows that are potentially critical for low-voltage grids. The study is based on the ewi ER&S model for the analysis of consumer behaviour (COMODO) and analyses the flexibility potentials for the year 2030.

Final report of Virtuelles Institut Strom zu Gas und Wärme
The „Virtual Institute Power to Gas and Heat“ (Virtuelles Institut Strom zu Gas und Wärme – VI SGW) is a consortium of seven scientific and technical institutes funded by the state of North Rhine-Westphalia and by the Cluster EnergieForschung of EnergieAgentur.NRW, which together conduct research on flexibility options for the future power-gas-heating integrated system. Alongside in-depth research on innovative technology pathways and energy system transformations, the work presented also includes the construction of a demonstration facility at the “Gas und Wärme” Institute in Essen. The Virtual Institute submitted the results of its work in five volumes. The Management Summary provides an overview of the results of the research that was carried out in the VI SGW project between 2015 to 2017. Since the results of the cooperation are extensive, the Management Summary is designed to aid the reader in understanding the structure of the analysis and allowing topics of interest to be quickly located within the five volumes. The five volumes of the final report are “Volume I: System and Location Analyses”; “Volume II: Analyses of Technology Pathways”; “Volume III: Accompanying Experimental Research”; “Volume IV: Appendix to Volumes I-III”; “Volume V: Technology Datasheets”. ewi ER&S is a partner and co-coordinator of the Virtual Institute SGW project, coordinating and contributing to “Volume I: System and Location Analyses” as well as contributing to “Volume II: Analyses of Technology Pathways” and “Volume V: Technology Datasheets”. The Management Summary and all volumes of the final report can be found on the project’s website via the external link below.

Final report: The role of Power-to-gas in the context of the energy transition
The study examines, from an economical perspective, the role power-to-gas (PtG) technologies may play in interlinking various sectors (namely electricity, heat and transport). The use of PtG technologies is analyzed for a wide range of applications including chemical storage, PtG in the industrial sector, the (potential) reduction of extensions in the high-voltage grid, power to heat (PtH) in the heating sector and power-to-gas-to-liquid (PtGtL) fuels for road transport.

Starting Conditions for the Marketing of Demand Flexibility – Status Quo Analysis and Metastudy
This study by ewi ER&S, Fraunhofer FIT and FIM is part of the research project SynErgie which is funded by the German Federal Ministry of Education and Research for the enabling of the energy intensive industries in Germany to adapt the demand for electricity to the increasingly fluctuating supply of electricity. This study first describes the fundamentals of electricity market design and the legal framework. The reference to the application to industrial processes is always taken and potential barriers to the participation of flexible demand processes are worked through. The analysis serves the cluster-wide information about the status quo of market structures and regulatory framework conditions. In addition, the project partners analyze scientific findings on the subject of demand flexibility and prepare them in a comprehensive meta-study.
