Strongly correlated and spatially concentrated curtailment of power plants strongly affects the electricity market. Such curtailment is observed during heat waves in middle Europe, for example. First, curtailed power plants need to be substituted by more expensive ones. Second, additional...

Im Zuge der Energiewende hat die Bundesregierung weitreichende Energieeffizienzziele definiert. Für die energetische Sanierung des Bestandes an Wohngebäuden wird eine Verdopplung der jährlichen Sanierungsrate von ein auf zwei Prozent angestrebt. Das DIW Berlin hat die hierfür notwendigen...

As part of the energy transition process, the German government has set far-reaching energy efficiency targets, including doubling the annual rate of building renovation to upgrade energy performance from one to two percent. DIW Berlin has estimated the additional energy-savings-related...

We analyze the pass-through of cost changes to retail tariffs in the German electricity market over the 2007 to 2014 period. We find an average pass-through rate of around 60%, which significantly varies with demand factors: while the pass-through rate to baseline tariffs, where firms have...

Space heating and hot water expenditures make up the majority of household energy demand in Germany, at 83.2%, making them an attractive target for energy policies. Using a panel dataset derived from yearly residential household surveys covering the years 1996 to 2014, we identify the...

Within the German welfare system, heating expenditures of recipients are in general fully covered by the government. This paper empirically tests for the hypothesis that households receiving welfare payments turn to over consumption of residential space heating. We use microdata from two...

Integrating large amounts of electrolyzer capacities poses particular challenges for grid operators along the entire hydrogen value chain. This research examines how hydrogen production capacities that support the decarbonization of German industrial sectors impact the electricity transmission...

Thermoelectric power plants depend on cooling water drawn from water bodies. Low river run-off and/or high water temperatures limit a plant's production capacity. This problem may intensify with climate change. To what extent do such capacity reductions affect electricity spot markets? Who bears...

Im Zug der Energiewende sind in den letzten Jahren die Anforderungen an das Stromnetz kontinuierlich gestiegen, insbesondere wird die Optimierung der Nutzung vorhandener Ressourcen durch das sogenannte Engpassmanagement - den Umgang mit Engpässen im Netz - bedeutsamer. Vor diesem Hintergrund...

This paper conducts an empirical analysis of risk premiums in the German day-ahead Electricity Wholesale Market. We compare hourly price data of the European Energy Exchange (EEX) auction and of the continuous over-the-counter (OTC) market taking place prior to EEX. As OTC price data are not...
