    Electricity from renewable sources often cannot be generated when and where it is needed. To deal with these temporal and spatial discrepancies, one frequently proposed approach is to expand storage capacities and transmission grids. It is often argued that the two technologies substitute each other, such that deploying one reduces the need for the other. Using a theoretical model, we show that storage capacities and transmission grids can also be complements if electricity system costs are minimized. We present the conditions that determine the kind of interdependence at specific storage locations: the characteristics of transmission congestion and the alignment of marginal generation costs between adjacent regions. By applying our theoretical insights to Italian power system data, we obtain empirical evidence that storage and transmission can act as either substitutes or complements. Planners of long-lasting and costly infrastructure can use the results to avoid design errors such as a misplacement of storage within the system.

    This article presents an approach to minimize the outage costs during power supply disruptions and, thus, to incentivize efficient resilience investment by network users. The central problem to be solved is the information asymmetry between network operators and network users on outage and backup costs. We present an auction of priority positions among network users based on the Vickrey-Clarke-Groves mechanism, using a numerical example, to solve the problem. Under the mechanism, each winning bidder pays for the externality exerted on the other bidders by holding a certain position, excluding her own bid, which induces truthful bidding. Minimizing the damage from power supply interruptions, the mechanism improves the resilience of the power system not only in the short term but also in the long term.

    This paper presents an approach for resilience incentives in the regulation of electricity network operators. Resilience is the ability of the power system to deal quickly and efficiently with large-scale and long-lasting power interruptions. It comprises two related aspects: minimizing the damage caused by an outage and increasing the robustness of the system. The resilience regulation proposed in this paper contains two complementary parts. First, a resilience incentive mechanism, which aims at internalizing external effects of resilience improvement. This part relies on so-called duration-dependent consumer damage functions (CDFs). Second, a forward-looking budget approach with a sharing factor to strengthen incentives for resilience expenses within regulatory constraints.

    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 the consequent costs? How is this influenced by climate change and a change in the electricity generation system? We quantify these effects by means of a bottom-up power generation system model. First, we simulate the German electricity spot market during the heat wave in 2006, and then conduct a sensitivity study that accounts for future climatic and technological conditions. We find an average price increase of 11%, which is even more pronounced during times of peak demand. Production costs accumulate to additional but moderate € 15.9 m during the two week period. Due to the price increase producers gain from the heat wave and consumers disproportionately bear the costs. Carbon emissions increase during the heat wave. The price and cost effects are more pronounced and significantly increase if assumptions on heat-sensitive demand, hydro power capacity, net exports and capacity reductions are tightened. These are potential additional effects of climate change. Hence, if mitigation fails or is postponed globally, the impacts on the current energy system are very likely to rise. Increases in feed-in from renewable resources and demand-side management can counter the effects to a considerable degree. Countries with a shift to renewable energy supply can be expected to be much less susceptible to water scarcity than those with a high share of nuclear and coal-fired power plants.

    Market design for electricity often ignores network congestion initially and addresses it in a second, so-called 'redispatch' stage. For market participants, any two-stage design offers an opportunity to strategically optimize between the different market stages. The current debate is how to design a market-based redispatch to integrate new actors, in particular consumers, given increasing levels of congestion. Strategic bidding may occur if market players anticipate congestion in their region and manipulate bidding to exploit this congestion. In this paper, we pick up the current debate and study the precise incentives for gaming with respect to competitive conditions on the market with a formal model. We propose that depending on competitive conditions, the expected profits of gaming can be negative and link the range of negative expected gaming profits to a so-called reference bidder, reflecting competitive conditions in the market. We also discuss how several potential remedies can increase the risk of the gaming strategy and can thereby reduce the practical potential for gaming. With this paper, we provide the theoretical framework for authorities and empirical works to assess the potential of market-based as opposed to administrative redispatch.

    Climate change poses a new challenge in particular to long-lasting electricity networks. At the same time, this industry is highly regulated, which greatly affects the behavior of network operators. In this paper, the impact of regulation in general and of the German electricity grid regulation in particular on anticipatory adaptation investments is analyzed. The qualitative analysis shows that in general a whole set of elements of the regulatory model and their coordination influence the decision of ex ante adaptation to climate change. A careful and balanced design, e.g. of efficiency and quality measurement, is thus crucial to avoid inadequate adaptation. The regulation in Germany discourages flexible adaptation to extreme weather events (EWEs). For irreversible adaptation of new and existing infrastructure to EWEs, the incentives highly depend on the cost approval of the regulator. Currently, the regulation discourages this type of adaptation. But if the additional costs can be claimed, the network operator is indifferent to adapt. Similarly, incentives to irreversibly adapt existing and new infrastructure to slow onset events (SOEs) range between excessively high and undistorted depending on the regulator’s discretion. Undistorted means that the decision to implement adaptation measures is not biased by regulation. Undistorted are also the incentives for flexible measures to adapt to SOEs. Only in the undistorted cases, the risk of inadequate adaptation are borne by the network operator.

    The market-based procurement of system services for network operators is gaining momentum in the current debate about the future market design in the energy sector. Since current sources of reactive power are primarily fossil-fuel power plants which will not be available in a carbon neutral energy system, reactive power will be sources from distributed assets in the electricity networks. The German regulator has proposed new rules for reactive power procurement, which are based on three pillars: The technical connection agreements, fully integrated network components owned by the network operators and market-based procurement. While this approach is primarily aiming at the reactive power demand on the transmission grid level, assets from the medium voltage grid can participate in this process as well. We evaluate this approach from an economic perspective and conclude that while such a three-pillar system can secure an effective provision of reactive power, the efficiency heavily depends on the regulatory system and that it provides the correct incentives for the network operator.
