Beyond the "Grid-Lock" in Electricity Interconnectors: The Case of Germany and Poland

The common European electricity market requires both market integration and transmission grid expansion, including trans-border interconnectors. Although the benefits of increased interconnectivity are widely acknowledged, expansion of interconnectors is often very slow. This paper gathers insights on the reasons behind this “grid-lock” drawing on the study of the German-Polish border. Although two ...

Network Expansion to Mitigate Market Power: How Increased Integration Fosters Welfare

Lack of transmission capacity hampers the integration of the European electricity market, and thereby precludes reaping the full benefits of competition. We investigate the extent to which transmission grid expansion promotes competition, efficiency and welfare. This work proposes a three-stage model for grid investment: a benevolent planner decides on network upgrades, considering welfare benefits ...

National-Strategic Investment in European Power Transmission Capacity

The transformation of the European energy system requires substantial investment in transmission capacity to facilitate cross-border trade and to efficiently integrate renewable energy sources. However, network planning in the EU is still mainly a national prerogative. In contrast to other studies aiming to identify the pan-European (continental) welfare-optimal transmission expansion, we investigate ...

On Distributive Effects of Optimal Regulation for Power Grid Expansion

To date, the distributive implications of incentive regulation on electricity transmission networks have not been explicitly studied in the literature. More specifically, the parameters that a regulator might use to achieve distributive efficiency under price-cap regulation have not yet been identified. To discern these parameters is the motivation for the research presented in this paper. We study ...

Responsive Feed-in Tariff Adjustment to Dynamic Technology Development

This paper reviews the adjustments of the feed-in tariffs for new solar photovoltaic (PV) installations in Germany. As PV system prices declined rapidly since 2009, the German government implemented automatic mechanisms to adjust the remuneration level for new installations in response to deployment volumes. This paper develops an analytic model to simulate weekly installations of PV systems of up ...

Can the Market Stability Reserve Stabilise the EU ETS: Commentators Hedge Their Bets

In response to an imbalance between the demand and supply of permits within the European Union Emissions Trading System (EU ETS), the European Commission has proposed the introduction of a Market Stability Reserve (MSR). The MSR represents a quantity based automatic adjustment mechanism, which is designed to tackle the current surplus and introduce a degree of flexibility, allowing the system to respond ...

The Welfare Impact of Parallel Imports: A Structural Approach Applied to the German Market for Oral Anti-Diabetics

We investigate the welfare impact of parallel imports using a large panel dataset containing monthly information on sales, ex-factory prices, and further product characteristics for all 649 anti-diabetic drugs sold in Germany between 2004 and 2010. We estimate a two-stage nested logit model of demand, and on the basis of an oligopolistic model of multi-product firms, we then recover the marginal costs ...
