In entry-exit gas markets as they are currently implemented in Europe, network constraints do not affect market interaction beyond the technical capacities determined by the TSO that restrict the quantities individual firms can trade at the market. It is an up to now unanswered question to what...

Pricing of access to energy networks is an important issue in liberalized energy sectors because of the natural monopoly character of the underlying transport infrastructures. We introduce a general pricing framework for potential-based energy flows in arbitrarily structured transport networks....

The introduction of clean hydrogen as a future energy commodity has prompted significant interest in developing dedicated transportation and storage infrastructures as an enabler for cross-border hydrogen trade and cost-efficient supply. This paper addresses the complex challenges associated...

The interdependence of electricity and natural gas is becoming a major energy policy and regulatory issue in all jurisdictions around the world. The increased role of gas fired plants in renewable-based electricity markets and the dependence on gas imports make this issue particular striking for...

The Russian-Ukrainian crisis has revitalized the European concerns of supply disruptions of natural gas as experienced in 2006 and 2009. However, the European supply situation, regulation and infrastructure have changed since: imports are more diversified, EU member states better connected and a...

In this paper, we investigate productivity growth in 55 major Australian urban water utilities using nonparametric frontier techniques over the period 2005/06 to 2008/09. The five outputs included in the analysis are chemical and microbiological compliance, and the inverses of real loses per...

Purpose: The liquefied natural gas (LNG) business comprises a number of economic activities with inherent risks. This paper proposes an integrated modelling approach, as part of the investment decision making process, for optimising economic returns from LNG whilst taking into account...

Cross-country comparisons avoid the unsteady equilibrium in which regulators have to balance between economies of scale and a sufficient number of remaining comparable utilities. By the use of Data Envelopment Analysis (DEA), we compare the efficiency of the drinking water sector in the...

Environmental factors add complexity to the comparison between specific activities or entire entities. Decision making units with an inferior performance are tempted to invoke that their organization is different from the others in the data set. By reinterpreting and extending the metafrontier...

This paper analyzes the role of storage for economies facing the risk of a gas supply disruption. We characterize the optimal/competitive transitory dynamics (accumulation, drainage and target stock). We partially relax the irreversibility hypothesis, by extending the model in two directions:...
