The Impact of Transmission Development on a 100% Renewable Electricity Supply: A Spatial Case Study on the German Power System

In this paper, we analyze the interdependence between the structure of transmission infrastructure and the electricity mix, applied to the case of Germany today and into the future. In particular, we are interested in how an energy system based on a high share of distributed renewable sources operates under different transmission regimes, for example, copper plate or more constrained network topologies. ...

An Introduction to Transmission Network Investment in the New Market Regime

Transmission network investment has emerged as a pivotal problem for the electricity industry, as it adapts to the change from traditional to renewable generation, from large scale to distributed generation and from vertically integrated monopolies to vertically separated production stages in various states of competition. Because transmission coordinates the generation, distribution and sales activities ...

Wärmemonitor 2019: Klimaziele bei Wohngebäuden trotz sinkender CO2-Emissionen derzeit außer Reichweite

Die Emissionsminderung im Gebäudesektor ist ein zentraler Baustein der deutschen Energie- und Klimapolitik. Jährlich wertet das DIW Berlin die Entwicklung des Heizenergiebedarfs in deutschen Wohngebäuden anhand eines umfangreichen Datenbestands aus. In diesem Jahr werden zudem die daraus entstehenden CO₂-Emissionen berechnet und mit der Zielsetzung für das Jahr 2030 im Bundes-Klimaschutzgesetz verglichen. ...

Bei Wohngebäuden gab es in den vergangenen zehn Jahren nur wenige Einsparungen: Interview

Degrees of Displacement: The Impact of Household PV Battery Prosumage on Utility Generation and Storage

Reductions in the cost of PV and batteries encourage households to invest in PV battery prosumage. We explore the implications for the rest of the power sector by applying two open-source techno-economic models to scenarios in Western Australia for the year 2030. Household PV capacity generally substitutes utility PV, but slightly less so as additional household batteries are installed. Wind power ...

Fossil Natural Gas Exit – A New Narrative for the European Energy Transformation towards Decarbonization

This paper discusses the potential role of fossil natural gas (and other gases) in the process of the energy transformation in Europe on its way to complete decarbonization. Mainstream conventional wisdom has it that natural gas, perhaps in combination with other gases, should maintain an important role in the energy mix, first, as a “bridge fuel”, and then through a gradual transition toward decarbonized ...

Inform Me When It Matters: Cost Salience, Energy Consumption, and Efficiency Investments

Effective attention to information may play a prominent role in consumer choice for energy-intensive services and it may simply be a function of receiving timely information when consumption takes place. This paper investigates whether and why the timing of utility bills leads to salience bias in heat energy consumption. In Germany, the 12-month billing period varies across buildings with a significant ...

Electricity Storage and the Renewable Energy Transition

Frequency and Duration of Low-Wind-Power Events in Germany

In the transition to a renewable energy system, the occurrence of low-wind-power events receives increasing attention. We analyze the frequency and duration of such events for onshore wind power in Germany, based on 40 years of reanalysis data and open software. We find that low-wind-power events are less frequent in winter than in summer, but the maximum duration is distributed more evenly between ...
