We review the recent empirical research concerning market power on the Nordic wholesale market for electricity, Nord Pool. There is no evidence of blatant and systematic exploitation of system level market power on Nord Pool. However, generation companies seem from time to time able to take...

Capacity constraints on transmissions of electricity are raising an increasing policy concern as electricity markets are integrated around the world. But our understanding of the workings of such markets is still limited. The purpose of this paper is to highlight the impact of transmission...

I examine the effects of privatization, in the form of acquisitions, in the Swedish electricity distribution sector. As the majority of the distribution networks remained publicly owned, I use a synthetic control method to identify the effects on price and labor efficiency. In comparison to...

Electricity markets are becoming more integrated around the world. However, the knowledge of the effects of different auction formats on suppliers' strategies in the presence of transmission constraints and transmission costs is still very limited. In this paper, I analyze the performance of...

This paper develops a framework for analyzing the incentives of national transmission system operators (TSOs) to supply cross-border interconnection capacity in an international electricity market. Our results show that equilibrium transmission capacity is downward distorted, even in situations...

In a 'smart' electricity distribution network, flexible distribution resources (FDRs) can be coordinated to improve efficiency. But coordination enables whoever controls such resources to exercise market power. The paper establishes the following efficiency rankings of market structures:...

A successful transformation to a carbon neutral energy system requires the correct investments in transmission and production capacity. In a zonal pricing electricity market, the one proposed by the European Commission to integrate the European electricity markets, I analyze the effects that...

Zonal pricing electricity markets operate sequentially. First, the suppliers compete in a spot market. Second, to alleviate the congestion in the transmission line, in a redispatch market, the suppliers in the importing node are called into operation to increase their production, and the...

Market power in electricity wholesale markets arises when generators have incentives to mark up their offers above the cost of production.I model a transmission network with a single line. I derive optimality conditions for supply functions for generators who supply energy at both ends of the...

The world's first multinational electricity market was formed with the creation of the Nordic power exchange, Nord Pool. We analyze the incentives to undertake transmission network investment in the context of the liberalized Nordic electricity market. Welfare improving investment in a...
