    <description>Title: Green charged decision-making: How two-part remuneration, contract flexibility, and environmental nudging drive vehicle-to-grid participation
Authors: Vey, Meike; Namockel, Nils; Ruhnau, Oliver
Abstract: Electric mobility and renewable energy play key roles in the global energy transition. In this context, vehicle- to-grid technology, which enables bidirectional energy ´row between electric vehicles and the grid, could make electric vehicles usable as energy storage units, thus supporting grid stability and integration of renewable energy. However, the willingness of electric vehicle owners to participate in vehicle-to-grid contracts remains insufficiently understood, particularly regarding how they respond to speciîoc contract attributes. This paper addresses this gap by conducting a discrete choice experiment to evaluate the preferences of current and potential future German electric vehicle drivers for various vehicle-to-grid contract alternatives. We îond that cycle-based remuneration, ´rexible contract duration, and environmental nudging signiîocantly enhance consumer acceptance. Conversely, a lower guaranteed battery level and longer minimum plug-in durations negatively impact participation. We also test how respondent characteristics in´ruence participation and identify income-dependent preferences, such as lower-income individuals attributing a stronger preference to îoxed daily payments than higher-income individuals. Our differentiated îondings may be used to improve contract designs and marketing efforts to address the unique V2G preferences of various user segments.</description>

    <description>Title: A day late and a dollar short: Intertemporal revenue cap regulation considering stranded assets
Authors: Nussberger, Maria; Diers, Hendrik; Kienscherf, Philipp Artur
Abstract: The European Union's goal of carbon neutrality by 2050 requires a major reduction in natural gas use for residential heating. However, gas grid equipment, amortized over 45 years in most countries, risks becoming stranded assets. The literature suggests that regulatory shocks could justify enhanced cost recovery during the remaining grid use period to reduce social costs of asset stranding. Under revenue cap regulation, increased cost recovery and higher tariffs may prompt households to switch to alternative technologies. These premature defections risk undermining cost recovery and place additional financial burdens on remaining households. Regulators face a trade-off between efficient defections and cost recovery. This paper introduces an intertemporal equilibrium model to explore network tariffs and household responses under different revenue caps and analyze their welfare implications. We demonstrate that degressive front-loading is an optimal strategy, balancing cost recovery with household exits, reducing stranded assets, and minimizing social costs. Furthermore, we find that, under the predominant revenue cap schemes, total cost recovery is often not achieved. We also examine distributional implications, showing how tariffs burden heterogeneous households. This research offers insights for policymakers and regulators into mitigating stranded costs while managing household defection impacts in countries with revenue cap regulation and young gas grids.</description>

    <description>Title: Unlocking thermal flexibility for the electricity system by combining heat pumps and thermal storage
Authors: Sitzmann, Amelie
Abstract: The expansion of heat pumps drives the electrification of the heating sector which is important to achieve Germany's ambitious climate targets. This paper examines the impact of heat pumps in combination with thermal storage on the flexibility of the German electricity system in 2030, focusing on its market and grid impacts. A timely and spatially detailed electricity market and transmission grid model evaluates the impact of thermal storage. The results show that, overall, unlocking the flexibility of thermal storage consistently reduces total supply costs. However, while the flexibility provided by thermal storage supports the integration of RES and reduces supply costs in the dispatch, the use of flexibility increases grid violations and hence, redispatch measures. By further studying a model setup with locational marginal prices (LMPs), the analysis highlights regional differences in the value of flexibility, which is particularly high in northern Germany, where proximity to wind generation enhances the benefits of thermal storage.</description>

    <description>Title: Flexibility in electricity wholesale markets and distribution grids: An integrated model and its application to electric vehicles in Germany
Authors: Lilienkamp, Arne; Namockel, Nils; Ruhnau, Oliver
Abstract: The ongoing transition of our energy systems implies a rise of distributed generators, batteries, and new consumers, including electric vehicles and heat pumps. Previous studies have found that distributed flexibility may substantially benefit wholesale electricity markets, but have neglected that these benefits may be subject to distribution grid constraints. Here, we propose using a virtual storage approach to aggregate the net load and flexibility of individual consumers at the distribution grid level, subject to the corresponding grid constraints. We apply our approach to flexible electric vehicle charging scenarios in German distribution grids for the years 2030 and 2045. Our results suggest that distributed flexibility exacerbates distribution grid congestion if it only follows wholesale market prices. However, there may be the potential to allevi- ate local congestion with stable wholesale market benefits of distributed flexibility. Local coordination of distributed flexibility appears to be able to resolve distribution grid constraints at substantially lower costs than expanding transformer capacity. We conclude that local coordination mechanisms are key to unlocking the wholesale market benefits of distributed flexibility while mitigating hazards in the distribution grids.</description>
