A Comparison of Single- and Multi-parameter Wave Criteria for Accessing Wind Turbines in Strategic Maintenance and Logistics Models for Offshore Wind Farms
Sperstad, Iver Bakken; Halvorsen-Weare, Elin Espeland; Hofmann, Matthias; Nonås, Lars Magne; Stålhane, Magnus; Wu, MingKang (Journal article; Peer reviewed, 2014)Different vessel types for transferring technicians for maintenance and inspection of offshore wind farms are often evaluated and compared by their limiting significant wave height for accessing the wind turbines. The ... -
Cost-benefit Evaluation of Remote Inspection of Offshore Wind Farms by Simulating the Operation and Maintenance Phase
Netland, Øyvind; Sperstad, Iver Bakken; Hofmann, Matthias; Skavhaug, Amund (Journal article; Peer reviewed, 2014)This paper presents a cost-benefit evaluation that investigates the potential economic benefits of using remote inspection technology for offshore wind farms. Remote inspection consists of a robot system inside the turbine ... -
Grid Tariffs for Peak Demand Reduction: Is there a Price Signal Conflict with Electricity Spot Prices?
Bjarghov, Sigurd Nikolai; Hofmann, Matthias (Chapter, 2022)The electricity grid is expected to require vast investments due to the decarbonization-by-electrification trend, calling for a change in grid tariff design which provides proper incentives for reducing peak loads. However, ... -
Implicit demand side flexibility as an alternative to investments in the transmission grid
Hofmann, Matthias (Doctoral theses at NTNU;2024:427, Doctoral thesis, 2024)The energy system is undergoing a significant transition to fulfil the climate goals and reduce emissions from fossil fuels. Energy demand, currently met by fossil fuels, must be replaced on a large scale by electricity. ... -
Maintenance Strategies for Large Offshore Wind Farms
Scheu, Matti Niclas; Matha, Denis; Hofmann, Matthias; Muskulus, Michael (Journal article; Peer reviewed, 2012)Up to one third of the total cost of energy from offshore wind generation is contributed by operation and maintenance (O&M). Compared to its onshore counterpart, this fraction is significantly higher. Costs are not only ... -
Norsk leveringspålitelighet er for god: Overestimerer dagens KILE-satser den samfunnsøkonomiske kostnaden av strømbrudd i handels- og tjenestenæringen?
Berre, Eirik Hernes; Garred, Annabel (Master thesis, 2020)Denne oppgaven ser på dagens ordning for å beregne de samfunnsøkonomiske kostnadene av et strømbrudd, KILE-satsene. KILE-satsene benyttes til å regulere nettselskaper og vurdere nytte-kostnadsforholdet i utbyggingen av ... -

Norwegian hourly residential electricity demand data with consumer characteristics during the European energy crisis
Hofmann, Matthias; Bjarghov, Sigurd Nikolai; Nessa, Stian (Peer reviewed; Journal article, 2023)This dataset was collected to understand how Norwegian households responded to the electricity price shock due to the European energy crisis. It consists of consumer characteristics and their self-reported responses to the ... -
Price elasticity of electricity demand in metropolitan areas – Case of Oslo
Hofmann, Matthias; Lindberg, Karen Byskov (Journal article; Peer reviewed, 2019)This paper investigates how the electricity demand in the main Norwegian metropolitan area Oslo responds to variable electricity prices and if it contributes to lower peak demand for electricity. The electricity demand in ... -
Prosumers’ role in the future energy system
Askeland, Magnus; Backe, Stian; Fagerstrøm, Jonathan; Crespo del Granado, Pedro; Hofmann, Matthias; Jaehnert, Stefan; Kvellheim, Ann Kristin; Marañon-Ledesma, Hector; Midthun, Kjetil Trovik; Seljom, Pernille Merethe Sire; Skjølsvold, Tomas Moe; Sæle, Hanne; Throndsen, William (Research report, 2018) -
A rich dataset of hourly residential electricity consumption data and survey answers from the iFlex dynamic pricing experiment
Hofmann, Matthias; Siebenbrunner, Turid (Peer reviewed; Journal article, 2023)The iFlex field experiment was conducted to understand if and how households change their power consumption in response to variable hourly electricity prices. This experiment was conducted in several Norwegian regions, and ... -
Sensitivity Analysis of O&M Costs for Offshore Wind Farms
Hagen, Brede Andre Larsen (Master thesis, 2013)The offshore wind farm industry is challenged by high costs related to operation and maintenance (O&M), and a study on how to significantly reduce these costs is essential to make this industry competitive with other energy ...
