Electricity production in a hydro system with a reservoir constraint
Mathiesen, Lars; Skaar, Jostein; Sørgard, Lars (2011:03, Working paper, 2011-02)The purpose of this article is to analyze how market power may affect the allocation of production between seasons (summer and winter) in a hydro power system with reservoir constraints and inflow uncertainty. We find that ... -
Market power and storage in electricity markets
Skaar, Jostein (Doctoral thesis, 2004) -
Policy measures and storage in a hydropower system
Skaar, Jostein (Discussion paper, Working paper, 2004-02)In this paper we discuss how three different public policy measures affect water storage controlled by hydropower producing firms. In particular we discuss measures to promote competition, increase transmission capacity ... -
Regulering av klimagassutslipp ved en deregulering av elektrisitetsmarkedene i Europa
Hatlebakk, Magnus; Hope, Einar; Skaar, Jostein (Arbeidsnotat, Working paper, 2001-02)Forprosjektet tar opp noen problemstillinger knyttet til samspillet mellom elektrisitetsmarkeder og et kvotemarked for CO2 utslipp i Europa. I arbeidsnotatet redegjøres det for teorien for regulering ved bruk av kvotemarkeder ... -
Supply function equilibria in a hydropower market
Skaar, Jostein (Working paper, Working paper, 2003-08)The purpose of this working paper is to study the implications of market power in a hydropower based electricity market within the framework of the Supply Function Equilibria (SFE) model. We start by developing the standard ... -
Temporary bottlenecks, hydropower and acquisitions
Skaar, Jostein; Sørgard, Lars (Discussion paper, Working paper, 2004-11)The purpose of this article is to study the effects of an acquisition in a hydro power system with temporary bottlenecks. We apply a model with four markets: two regions and two time periods. It is shown that an acquisition ... -
Temporary bottlenecks, hydropower and acquisitions in networks
Skaar, Jostein; Sørgard, Lars (Working paper, Working paper, 2003-01)The purpose of this article is to study the effects of an acquisition in an energy system dominated by hydropower and with temporary bottlenecks. We apply a model with four markets: two regions and two time periods. It is ... -
Temporære flaskehalser og oppkjøp i norsk kraftforsyning
Skaar, Jostein; Sørgard, Lars (Arbeidsnotat, Working paper, 2002-06)I dette notatet drøfter vi hvordan et oppkjøp vil påvirke prissettingen i et vannkraftsystem der produsentene må fordele sin produksjon over to perioder og det forekommer temporære flaskehalser. Vi viser at i en slik ... -
Temporære flaskehalser og oppkjøp i norsk kraftforsyning : et svar til von der Fehrs kommentarer
Skaar, Jostein; Sørgard, Lars (Arbeidsnotat, Working paper, 2002-06)I Skaar og Sørgard (2002) konkluderte vi med at den samfunnsøkonomiske lønnsomheten av et oppkjøp i et vannbasert kraftsystem er tvetydig i en situasjon med temporære flaskehalser og gitt total produksjon. von der Fehr ... -
Water with power : market power and supply shortage in dry years
Mathiesen, Lars; Skaar, Jostein; Sørgard, Lars (Discussion paper, Working paper, 2003-12)The purpose of this paper is to analyse how market power may affect the allocation of production between seasons (summer and winter) in a hydro power system with reservoirs and where inflow in winter is uncertain. We find ...
