The patchwork of different imbalance-settlement rules in geographically adjacent gas regions induces shippers to go “forum shopping” to minimize costs of ex-post balancing services. This shopping increases efficiency, and thus welfare of the shippers, on the one hand. The impact on net...

This paper analyzes the value and cost of line-pack flexibility in liberalized gas markets through examination of the techno-economic characteristics of gas transport pipelines and the trade-offs between different ways to use the infrastructure: transport and flexibility. Line-pack flexibility...

CO2 cap-and-trade mechanisms and CO2 emission taxes are becoming increasingly widespread. To assess the impact of a CO2 price, marginal abatement cost curves (MACCs) are a commonly used tool by policy makers, providing a direct graphical link between a CO2 price and the expected abatement....

In the transition towards a low-carbon future in Europe, cities' actions are of major importance due to the prominence of urbanization, both in terms of population and in terms of greenhouse gas (GHG) emissions. As a result, we need city authorities to act, by using their competences as policy...

The combination of the ambitious German greenhouse gas reduction goals in the power sector and the nuclear phase-out raises many questions concerning the operational security of the German electricity generation system. This paper focusses on the technical feasibility (electricity generation and...

This paper investigates the impact of the economic recession on CO2 emissions in the European power sector, during the years 2008 and 2009. Three main determinants of the power sector's emissions are identified: the demand for electricity, the CO2 price, and fuel prices. A counterfactual...

Electricity storage is considered as a valuable source of flexibility with applications covering the whole electricity value chain. Most of the existing evaluation methods for electricity storage are conceived for one specific use of the storage, which often leads to the conclusion that the...

As of 2005, electricity generators in Europe operate under the European Union Emission Trading System (EU ETS). At the same time, European Member States have launched support mechanisms to stimulate the deployment of renewable electricity sources (RES-E). RES-E injections displace CO2 emissions...

As Europe wants to move towards a secure, sustainable and competitive energy market, it has taken action, amongst other, to support electricity from renewable energy sources (RES-E) and to mitigate CO2 emissions. This paper first qualitatively discusses price- and quantity-based measures for...
