| Summary/Abstract |
This paper surveys climate and energy policy in the EU transport sector covering the road, aviation, and shipping sectors. We summarise current policies, focusing on the Fit for 55 Package, and link the different instruments being used (e.g. cap-and-trade, tax, mandate, performance standard, or subsidy) to different sources of market failure. Next, we analyse the static and dynamic cost-efficiency of the policies and instruments. We find that they address a range of market inefficiencies, but that there are still a number of aspects that can further improve the cost-effectiveness of current EU climate policies in the transport sector. For example, higher taxes and emission performance standards for aviation and shipping, the right combination of research and innovation investments and learning-by-doing policies, and balancing implicit carbon prices by revising the road tax system and adding congestion tolls and charges. Finally, European policy has important side effects on the rest of the world that need to be taken into account in the selection of policies. This improved set of policies can support a sustainable recovery and reach the European Union's climate targets at the lowest cost.

| Summary/Abstract |
The value of lost load (VOLL) is an essential parameter for power system reliability. It represents the cost of unserved energy during power interruptions. Various studies have estimated this parameter for different countries and more recently, for different interruption characteristics – such as interruption duration, time of interruption and interrupted consumer. However, it is common practice in system operation and the literature to use only one uniform VOLL. Our theoretical analysis shows that using more-detailed VOLL data leads to more cost-effective transmission reliability decisions. Using actual consumer- and time-differentiated VOLL data from Norway, Great Britain and the United States, numerical simulations of short-term power system reliability management indicate a potential operational cost decrease of up to 43% in a five-node network, and between 2% and 18% in a more realistic 118-node network – mainly because of lower preventive redispatch costs in response to lower expected interruption costs. However, changed reliability practices could lead to opposition, if some consumers are disproportionately interrupted and not adequately compensated. Although the first policy measures to collect more detailed and harmonized VOLL data have been taken, future policy should improve transmission-distribution coordination and enable the participation of all consumers in curtailment programs, through smart meters and smart appliances.

| Summary/Abstract |
This paper studies the consistency between two contradictory policies in the electricity industry. On the one hand, electricity systems are increasingly interconnected. On the other hand, reliability standards, whose value was typically set when countries were hardly interconnected, are still enforced at the national level. We show that enforcing autarky reliability standards may still reach the welfare optimum in the presence of interconnections, but only under two conditions. First, installed generation capacities should be determined jointly, while considering the whole power system. Second, reliability calculations should fully internalize external adequacy benefits occurring in neighboring systems. We run a numerical application for a set of European countries and find that existing interconnections may lead to generation adequacy benefits of around one billion euros per year, by enabling a 18.9 GW decrease in generation capacity. In our case study, regional coordination is found to be more important than fully internalizing external reliability benefits in adequacy simulations.
