To ensure security of supply in the power sector, many countries are considering capacity mechanisms. Simultaneously, the expansion of variable renewables increases the need for power sector flexibility, with promising options on the demand side. We analyze how a centralized capacity market and an advanced reliability reserve with a moderately high activation price affect demand-side flexibility investments ...

This paper analyses determinants of pass-through for Germany’s 2022 temporary fuel discount at its implementation and subsequent termination. Based on a unique dataset of fuel station characteristics and prices, we employ a two-stage Regression Discontinuity in Time (RDiT) methodology to estimate spatial passthrough variation. Our findings indicate that horizontal and vertical market structures exert ...

The transition to decarbonized energy systems has fueled a controversial debate over the necessity of traditional ‘‘baseload’’ power. Skepticism remains regarding the reliability and economic feasibility of power systems relying mainly on cheap variable renewable energy (VRE) sources. Addressing this, the German Academies’ project ‘‘Energy Systems of the Future’’ (ESYS) analyzed the role of baseload ...

For a successful energy transition, the FAIR data principles provide an essential framework for managing and reusing energy related data for research, yet their implementation remains limited. In this explorative study, we empirically examine how energy researchers engage with energy data in relation to FAIR data principles, research data platforms, and open science practices, while acknowledging the ...

This study examines the payout policies of modern state-owned enterprises (SOEs) using unique official statistics on German SOEs from 2003 to 2014. The findings reveal that agency conflicts significantly influence SOEs’ payout behavior, leading to payout smoothing over time. Vertical agency costs, arising from owner-manager conflicts, and horizontal agency costs, stemming from owner-owner conflicts, ...

Coping with prolonged periods of low availability of wind and solar power, also referred to as variable renewable energy droughts or “Dunkelflaute”, emerges as a key challenge for realizing decarbonized energy systems based on renewable energy. Here we investigate the role of long-duration electricity storage and geographical balancing through transmission in dealing with such events in Europe, combining ...

Current energy projections often envision an expansion of nuclear capacities to decarbonize future energy systems. However, this contrasts with the historic and current status of the nuclear industry, marked by techno-economic challenges for both light-water and non-light-water reactor technologies. Regardless, projections of strong nuclear growth have persisted since the 1970s. This paper investigates ...

This paper analyses the determinants of peoples’ decision to purchase public transport season tickets. Based on the Deutschlandticket, it focuses on identifying primary customer groups, the role of public transport irregularities such as delays and cancellations, and behavioural inertia of repetitive purchase decisions. It builds on a panel dataset covering survey answers and GPS tracking data from ...

Nuclear fusion is envisioned for near-term energy generation deployment, with projected timelines for commercial deployment of fusion expected for the 2030s. Previous research has been limited to either economic or technological maturity assessments of the sector. To address this gap, we design a novel framework that evaluates fusion projects across the most common reactor types and derives the trajectories ...

Sector coupling (SC), the integration of energy vectors and end-use sectors, is increasingly central to the net-zero transition but remains conceptually fragmented. This fragmentation causes modeling inconsistencies, hinders cross-study comparison, and undermines energy policy coordination. We address this gap through a structured mapping of existing definitions, categorizing them along three dimensions, ...
