Analysis of CO2-emissions and power market consequences from electrification of offshore petroleum installations

Electrification of Utsira is planned with a start-up in 2022 and will greatly increase the power demand in the southern part of Norway. By simulating the future Nordic power system, the aim of this thesis is to analyze the impact of an electrification on the power system. Areas of focus will be power production, emissions, power prices and power exchange. The results show that the total emissions in the system in 2055 compared to 2019 is about one third. This is mostly due to a great increase in installed wind capacity. At the same time, thermal power production is reduced greatly. Electrification will lead to slightly higher emissions, but as the power system has an increasing share of renewable power production the net emissions change after electrification is still negative
