• Determinants of oil and gas investments on the Norwegian Continental Shelf 

      Berntsen, Martin A.S; Bøe, Kristine; Jordal, Therese; Molnar, Peter (Journal article; Peer reviewed, 2018)
      This paper studies the investment decisions by oil and gas companies operating on the Norwegian Continental Shelf. We account for the heterogeneity across the fields by including field-specific variables, including geological ...
    • From linking to integration of energy system models and computational general equilibrium models - Effects on equilibria and convergence 

      Helgesen, Per Ivar; Tomasgard, Asgeir (Journal article; Peer reviewed, 2018)
      This paper compares hard-linked and integrated approaches of hybrid top-down and bottom-up models in terms of equilibria and convergence. Four setups where a bottom-up linear programming model is hard-linked with a top-down ...
    • Green electricity investment timing in practice: Real options or net present value? 

      Fleten, Stein-Erik; Linnerud, Kristin; Molnar, Peter; Nygård, Maria Tandberg (Journal article; Peer reviewed, 2016)
      Using data from 214 hydropower projects in Norway we study whether investors in renewable energy projects exert discretion about the timing of investment decisions. We know from interviews with these investors that they ...
    • Green investment under policy uncertainty and Bayesian learning 

      Dalby, Peder A.O.; Gillerhaugen, Gisle R.; Hagspiel, Verena; Leth-Olsen, Tord; Thijssen, Jacco J.J. (Journal article; Peer reviewed, 2018)
      Many countries have introduced support schemes to accelerate investments in renewable energy (RE). Experience shows that, over time, retraction or revision of support schemes become more likely. Investors in RE are greatly ...
    • Investment Timing under Uncertain Renewable Energy Policy: An Empirical Study of Small Hydropower Projects 

      Linnerud, Kristin; Andersson, Ane Marte; Fleten, Stein-Erik (Journal article; Peer reviewed, 2014-12-15)
      Policy uncertainty can be a powerful deterrent to immediate investments.} Based on panel data of 214 licenses to construct small run-of-the-river hydropower plants, we examine whether the prospect of a common Swedish-Norwegian ...
    • Linepack storage valuation under price uncertainty 

      Arvesen, Øystein; Medbø, Vegard Gjelsvik; Fleten, Stein-Erik; Tomasgard, Asgeir; Westgaard, Sjur (Journal article; Peer reviewed, 2013)
      Natural gas flows in pipelines as a consequence of the pressure difference at the inlet and outlet. Adjusting these pressures makes it possible to inject natural gas at one rate and withdraw at a different rate, hence using ...
    • Market power, fuel substitution and infrastructure - A large-scale equilibrium model of global energy markets 

      Huppmann, Daniel; Egging, Ruud (Journal article; Peer reviewed, 2014)
      Assessing and quantifying the impacts of technological, economic, and policy shifts in the global energy system require large-scale numerical models. We propose a dynamic multi-fuel market equilibrium model that combines ...
    • Modeling the UK electricity price distributions using quantile regression 

      Hagfors, Lars Ivar; Bunn, Derek; Kristoffersen, Eline; Staver, Tiril Toftdahl; Westgaard, Sjur (Journal article; Peer reviewed, 2016)
      In this paper we develop fundamental quantile regression models for the UK electricity price in each trading period. Intraday properties of price risk, as represented by the predictive distribution rather than expected ...
    • Multi market bidding strategies for demand side flexibility aggregators in electricity markets 

      Ottesen, Stig Ødegaard; Tomasgard, Asgeir; Fleten, Stein-Erik (Journal article; Peer reviewed, 2018)
      Due to the electricity systems’ increasing need for flexibility, demand side flexibility aggregation becomes more important. An issue is how to make such activities profitable, which may be obtained by selling flexibility ...
    • Stochastic electricity dispatch: A challenge for market design 

      Bjørndal, Endre; Bjørndal, Mette; Midthun, Kjetil Trovik; Tomasgard, Asgeir (Journal article; Peer reviewed, 2018)
      We consider an energy-only electricity market where some generation and/or load is uncertain, and where there are flexibility costs, i.e. some conventional power plants have to be scheduled well before real time in order ...
    • The impact of Zero Energy Buildings on the Scandinavian energy system 

      Seljom, Pernille Merethe; Lindberg, Karen Byskov; Tomasgard, Asgeir; Doorman, Gerard L.; Sartori, Igor (Journal article; Peer reviewed, 2017)
      This paper investigates how an extensive implementation of net Zero Energy Buildings (ZEBs) affects cost-optimal investments in the Scandinavian energy system towards 2050. Analyses are done by a stochastic TIMES model ...
    • Tradable green certificates for renewable support: The role of expectations and uncertainty 

      Hustveit, Magne; Frogner, Jens Sveen; Fleten, Stein-Erik (Journal article; Peer reviewed, 2017)
      This paper analyzes tradable green certificate markets, where producers investing in new renewable capacity receive certificates based on their production. These are sold to electricity retailers, who are required to buy ...
    • Using a hybrid hard-linked model to analyze reduced climate gas emissions from transport 

      Helgesen, Per Ivar; Lind, Arne; Ivanova, Olga; Tomasgard, Asgeir (Journal article; Peer reviewed, 2018)
      In this paper we have hard-linked a bottom-up energy system model (TIMES) and a top-down computable general equilibrium model (REMES) in order to analyze both the energy system impacts and the economic impacts of reducing ...
