This thesis consists of four essays, mainly related to the fields of industrial organization and political economy. The focus is on deregulation of electricity retail markets and on the continued regulation of parts of such markets after the introduction of competition. The first essay is an empirical essay on the causes of deregulation. The timing of implementation of competition in retail electricity markets in the United States, Canada, Europe, Australia and New Zealand is studied. One conclusion is that there exist important qualitative differences between the United States and Europe. While deregulation in the United States to a large extent seems to have been driven by consumer interest concerns, the influence from interest groups is more pronounced in Europe.The second (theoretical) and third (empirical) essays deal with the interaction between the regulation of distribution networks and the retail market. When the regulated and unregulated operations are conducted within vertically integrated companies the regulation may not only have an effect on the regulated market, but also affect the behavior in the unregulated market. In the third essay a test that uses prices to detect patterns of cross-subsidization is developed and used on Norwegian data. Especially the effects of a regulatory change on cross-subsidization behavior are analyzed. The results both highlight the importance of a well-designed regulation of the regulated market and give support to requirements of vertical separation between regulated and unregulated operations.The fourth essay is a study of domestic electricity demand. It is thus somewhat different than the other papers since it is not directly connected to the issue of electricity market deregulation. Since the energy sector is an essential part of any modern economy and energy production has considerable environmental effects, the sector has for a long time been subject to political interventions. To some extent the policy instruments available to the legislator are reduced by deregulations. The use of taxes to affect prices and thus the demand for electricity may at the same time become an even more important policy instrument and more difficult to implement due to the internationalization of the electricity market. / Diss.

Competitive power markets from different countries exhibit a common market design, especially because of the nature of electricity (lack of storage, inelastic load, and strong seasonal effects on multiple time scales). For example, a majority of countries have created a spot market where electricity is traded hourly. The design of the spot markets reflected an ambition of providing strong incentives for efficient and least-cost production. Subsequently, the spot market price has been considered as a reference price for other existing electricity markets such as the contract market or the real-time market. However, empirical studies on electricity markets find some evidence of abnormally high markups. The literature on the electricity spot market mainly focuses on the producers' pricing decisions. The present thesis argues that quantity choices, both in terms of available as well as contracted quantities, are crucial for understanding market power in electricity markets. / Diss.

This report explores the impacts of variable renewable energy (VRE) on power trading in the European wholesale electricity market. The intricate operation of a typical power exchange in Europe is accompanied by an equally complex balancing system. The increasing amount of VRE in the power system, such as wind and solar power, has far-reaching impacts for power traders in both this electricity market and the corresponding balancing system. As a result, the electricity market is evolving in unprecedented ways and new participants are entering the playing field to capitalize on the changing dynamics caused by VRE generators. One novel participant, the virtual power plant (VPP), possesses an advantage over other market participants by aggregating VRE generators with controllable renewable energy generators, like biogas and hydro plants, into one entity. This allows the VPP to both gain access to live VRE production data that larger plants don’t have, which it then utilizes to remotely dispatch various subpools of assets, and to provide balancing services to the grid. Subsequently, VPPs are able to trade VRE and other renewable electricity superiorly on the same spot markets and balancing systems as large central power plants and industrial consumers. The report asserts that VPP traders can earn profits through means of innovative trading strategies that exploit predictable market impacts caused by VRE power through a robust understanding of the electricity market and their unique access to data. / Denna rapport undersöker effekterna av variabel förnybar energi (VRE) på krafthandeln på den europeiska elhandelsmarknaden för stora aktörer. Den komplicerade driften av ett typiskt kraftutbyte i Europa åtföljs av ett lika komplicerat balanseringssystem. Den ökande mängden VRE i kraftsystemet, såsom vind- och solkraft, har långtgående effekter för krafthandlare på både denna elmarknad och motsvarande balanseringssystem. Som ett resultat utvecklas elmarknaden på enastående sätt och nya deltagare kommer in på spelplanen för att dra nytta av den förändrade dynamiken som orsakas av VRE-generatorer. En ny spelare, det virtuella kraftverket (VPP), har en fördel jämfört med andra marknadsaktörer genom att samla VRE-generatorer med styrbara förnybara energiproducenter, som biogas och vattenkraftverk, till en enhet. Detta gör att VPP både kan få tillgång till live VRE-produktionsdata som större anläggningar inte har, som den sedan använder för att distribuera olika underpooler av tillgångar och för att tillhandahålla balanstjänster till nätet. Därefter kan VPP: er handla med VRE och annan förnybar el på ett överlägset sätt på samma spotmarknader och balanseringssystem som stora centrala kraftverk och industrikonsumenter. Rapporten visar att VPP-handlare kan göra vinster genom innovativa handelsstrategier som utnyttjar förutsägbara marknadseffekter orsakade av VRE-kraft genom en detaljerad förståelse för elmarknaden och unik tillgång till data för produktionen av förnybar energi / <p>QC 20201118</p>
