• Backing out Expectations from Hydropower Release Time Series 

      Boger, Maren; Fleten, Stein-Erik; Pichler, Alois; Keppo, Jussi; Vestbøstad, Einar Midttun (Conference object; Journal article; Preprint, 2017)
      Our goal is to study how price expectations are formed in an electricity market. In the context of a single hydropower producer in the Nordic market, we expect the forward curve to have a strong influence. The alternative ...
    • Can commodities dominate stock and bond portfolios? 

      Henriksen, Tom Erik Sønsteng; Pichler, Alois; Westgaard, Sjur; Frydenberg, Stein (Journal article; Peer reviewed, 2018)
      In this article we discuss whether commodities should be included as an asset class when establishing portfolios. By investigating second order stochastic dominance relations, we find that the stock and bond indices tend ...
    • Implied Efficiency Curves from Analysis of Operational Patterns 

      brelin, sebastian; Lien, Morten Adrian; Fleten, Stein-Erik; Keppo, Jussi; Pichler, Alois (Chapter, 2018)
      A reservoir manager at a hydropower plant has to decide whether to release water in order to produce electricity, and the level at which to produce. These production levels have different efficiencies as well as other ...
    • Observed switches and derived profitability indicators for peaking power plants: Northeast U.S. 2001–2009 

      Fleten, Stein-Erik; Haugom, Erik; Pichler, Alois; Ullrich, Carl J. (Journal article; Peer reviewed, 2019)
      The data are related to the research article “Structural estimation of switching costs for peaking power plants,” https://doi.org/10.1016/j.ejor.2019.03.031. Fleten et al., 2019 We display the operating status of peaking ...
    • Optimal Transmission Switching under Demand Uncertainty 

      Prydz, Mari Hardersen; Aarsten, Heidi (Master thesis, 2015)
      Denne oppgaven studerer optimeringsproblemet, Optimal Transmission Switching (OTS). Motivasjonen for denne oppgaven stammer fra våre observasjoner om at testcasene som er brukt til å evaluere potensialet til dette problemet ...
    • Policy Uncertainty and Real Options in Switching of Peak Generators 

      Fleten, Stein-Erik; Johansen, Marius; Pichler, Alois; Ullrich, Carl J. (Journal article, 2016)
      This paper examines empirically how economic factors, government policy, and strategic interactions affect manager’s decisions to switch between operating and stand-by states for peaking electric power generators. We model ...
    • Risk aversion in imperfect natural gas markets 

      Egging, Ruud; Pichler, Alois; Kalvø, Øyvind Iversen; Walle-Hansen, Thomas Meyer (Journal article; Peer reviewed, 2017)
      This paper presents a natural gas market equilibrium model that considers uncertainty in shale gas reserve exploration. Risk aversion is modeled using a risk measure known as the Average Value-at-Risk (also referred to as ...
    • Stochastic short-term hydropower planning with inflow scenario trees 

      Seguin, Sara; Fleten, Stein-Erik; Cote, Pascal; Pichler, Alois; Audet, Charles (Journal article; Peer reviewed, 2016)
      This paper presents an optimization approach to solve the short-term hydropower unit commitment and loading problem with uncertain inflows. A scenario tree is built based on a forecasted fan of inflows, which is developed ...
    • Structural Estimation Analysis in Hydropower Scheduling 

      Boger, Maren; Vestbøstad, Einar Midttun (Master thesis, 2016)
      When planning production, a hydro power reservoir managers need to form expectations for electricity prices in the future. When forming expectations, the Nordic electricity forward market is a useful tool for predicting ...
    • Structural Estimation of Switching Costs for Peaking Power Plants 

      Fleten, Stein-Erik; Haugom, Erik; Pichler, Alois; Ullrich, Carl J. (Journal article; Peer reviewed, 2019)
      We estimates costs associated with mothballing, restarting, abandoning and maintaining peaking power plants. We develop a real options model to explain switching and maintenance behavior of plant managers. The constrained ...
    • The effects of risk preferences on investments and trade in the natural gas market 

      Walle-Hansen, Thomas Meyer; Kalvø, Oyvind Iversen (Master thesis, 2014)
      In this thesis we have developed and solved a multi-stage stochastic mixed complementarity problem (MCP) for a natural gas market that accounts for market power and risk averse behaviour amongst producers using the risk ...
