Removing Cross-Border Capacity Bottlenecks in the European Natural Gas Market - A Proposed Merchant-Regulatory Mechanism, DIW Discussion Papers 1145, with Anne Neumann and Juan Rosellón, available

Abstract:
We propose a merchant-regulatory framework to promote investment in the
European natural gas network infrastructure based on a price cap over
two-part tariffs. As suggested by Vogelsang (2001) and Hogan et al.
(2010), a profit maximizing network operator facing this regulatory
constraint will intertemporally rebalance the variable and fixed part
of its two-part tariff so as to expand the congested pipelines, and
converge to the Ramsey-Boiteaux equilibrium. We confirm this with
actual data from the European natural gas market by comparing the
bi-level price-cap model with a base case, a no-regulation case, and a
welfare benchmark case, and by performing sensitivity analyses. In all
cases, the incentive model is the best decentralized regulatory
alternative that efficiently develops the European pipeline system.
Nachfragesicherung und Lastflüsse nach dem Abschalten von Kernkraftwerken in Deutschland – Sind Engpässe zu befürchten? / Security of Supply and Electricity Network Flows after a Phase-Out of Germany’s Nuclear Plants: Any Trouble Ahead?,

Abstract:
In dieser Studie werden die Auswirkungen des Kernkraftwerksmoratoriums
bzw. des vollständigen -ausstiegs auf das deutsche Elektrizitätssystem
ermittelt; insbesondere werden erstmalig die Energiebereitstellung und
die Lastflüsse im deutschen und mitteleuropäischen Elektrizitätsnetz
analysiert. Die Ergebnisse
weisen darauf hin, dass die fortgesetzte Abschaltung der sieben
Kernkraftwerke des Moratoriums keine ernsthaften Engpässe induziert;
ein vollständiger Ausstieg aus der Kernkraft in Deutschland ist
insbesondere vor dem Hintergrund der sich derzeit im Bau befindlichen
Kraftwerkskapazitäten in den nächsten 3-7 Jahren möglich.
This paper, which examines the impacts of phasing out nuclear power in
Germany, is the first to include an analysis of energy supply security
and critical line flows in both the German and Central European
electricity networks. We conclude that closing the seven nuclear power
plants within the government’s moratorium will cause no significant
supply security issues or network constraints and an eventual full
phase-out seem to be possible due to the completion of several new
conventional power plants now under construction. Finally, we suggest
that a nuclear phase-out in Germany within the next 3-7 years will not
undermine security of supply and network stability in Germany and
Central Europe.
