A Comparison of Risk Measures for Accidents in the Energy Sector and Their Implications on Decision-Making Strategies
(Journal article, 2018)Within the broader context of energy security and critical infrastructure protection, the comprehensive assessment of accidents and their related consequences are of high priority for many stakeholders. The risk of accidents ... -
Are green and blue hydrogen competitive or complementary? Insights from a decarbonized European power system analysis
(Peer reviewed; Journal article, 2023)Hydrogen will be important in decarbonized energy systems. The primary ways to produce low emission hydrogen are from renewable electricity using electrolyzers, called green hydrogen, and by reforming natural gas and ... -
Assessing the impact of energy communities on retailers’ balancing positions in the power market
(Peer reviewed; Journal article, 2023)As regulatory constraints limit energy communities’ (ECs) participation in wholesale markets, these might rely on retailers’ supply when local generation falls short. As balancing responsible parties, retailers are financially ... -
Chances and barriers for Germany's low carbon transition - Quantifying uncertainties in key influential factors
(Peer reviewed; Journal article, 2022)With the energy sector being one of the largest sources of global greenhouse-gas emissions, a swift change in the ways of energy generation and consumption is needed for a fulfilment of climate goals. But while the existence ... -
Comparing individual and coordinated demand response with dynamic and static power grid tariffs
(Peer reviewed; Journal article, 2020)This paper investigates cost-optimal operation of flexible electricity assets with a capacity-based power grid tariff involving power subscription. The purpose of this research is to identify the characteristics of a ... -
Day-ahead electricity price prediction applying hybrid models of LSTM-based deep learning methods and feature selection algorithms under consideration of market coupling
(Peer reviewed; Journal article, 2021)The availability of accurate day-ahead electricity price forecasts is pivotal for electricity market participants. In the context of trade liberalisation and market harmonisation in the European markets, accurate price ... -
Determinants of oil and gas investments on the Norwegian Continental Shelf
(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 ... -
Dynamic allocation of peer-to-peer clusters in virtual local electricity markets: A marketplace for EV flexibility
(Journal article; Peer reviewed, 2021)Local Electricity Markets (LEM) and peer-to-peer trading are new mechanisms to encourage the uptake of solar PV and to support the emergence of consumer-centric electricity markets. However, the coordination to trade between ... -
Efficient coordination of top-down and bottom-up models for energy system design: An algorithmic approach
(Journal article; Peer reviewed, 2023)To account for endogeneity effects in, e.g., energy demand, modern bottom-up energy system models are often linked to a top-down model describing the macroeconomic system. Solving such linked models involves iteratively ... -
From linking to integration of energy system models and computational general equilibrium models - Effects on equilibria and convergence
(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?
(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
(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
(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
(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
(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
(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 ... -
Modelling and analysis of offshore energy hubs
(Peer reviewed; Journal article, 2022)Clean offshore energy hubs may become pivotal for efficient offshore wind power generation and distribution. In addition, offshore energy hubs may provide decarbonised energy supply for maritime transport, oil and gas ... -
Multi market bidding strategies for demand side flexibility aggregators in electricity markets
(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 ... -
Performing price scenario analysis and stress testing using quantile regression: A case study of the Californian electricity market
(Peer reviewed; Journal article, 2020)This paper uses quantile regression to demonstrate how electricity price distributions are linked to fundamental supply and demand variables. It investigates the California electricity market (zone SP15) for selected trading ... -
