Welcome to the last lunch box webinar this semester. This one will be a bit different; we have three presenters on the agenda. They are master’s students and will present their work to us.
There will be time for questions and discussion.
Hope to see you there! We will back with new invitations in August.

This thesis studies the new interconnector NordLink’s effect on electricity prices in the Norwegian price area NO2 and in Germany. When examining the cable’s price effect, we assess how the price volatility has developed, whether price convergence between the areas has occurred, and if the highest price levels in Germany have been reduced. The study is conducted by estimating a quantile regression model for both areas. In the models, we control for various factors known to impact day-ahead electricity prices. The variable of interest is a dummy variable that marks the first exchange of electricity through NordLink, which allows for a before-after analysis of the cable’s price effect on both areas.
Our results indicate that NordLink has had a price-reducing effect in the German market, while it has increased prices in NO2 for the given period. Hence, price convergence between the previously separated markets is seen as an effect of the cable. The results also show that NordLink has had the most significant impact on German prices at the highest parts of its distribution, confirming a peak shaving effect. Moreover, the results show decreasing price volatility in Germany and partial evidence for volatility exacerbation in NO2.
Further, the thesis argues that through NordLink, gas and EUAs’ effect on electricity prices in NO2 has been strengthened. Additionally, we find renewables’ downward pressure on electricity prices to be strengthened in both areas after the opening of NordLink. In Germany, the price-reducing effect from NordLink is only found in conjunction with renewables.
The climate crisis is the biggest crisis facing humanity in the coming years. Our temperatures are rising, glaciers are melting, sea levels are rising and we are experiencing more extreme weather than ever before. At the same time as the consequences of the climate crisis become more extensive, we use more resources than we have, and this creates a pressure on the earth's capacity. The construction industry is a resource-intensive industry and accounts for a significant share of Norway's raw material extraction, waste production and energy consumption. In 2017 alone, the construction industry generated 1,896,557 tonnes of waste. Today's standard within the industry is based on linear practices which mainly means that outgoing materials from demolition processes or rehabilitation projects are sent to landfill or used for energy recovery. The main reason for linear practices is because the regulations and networks that govern the construction industry are also based on the same linear practices.
To counteract such a development, we need to use more environmentally friendly and sustainable practices. One way to contribute to achieving these goals is through reuse of building materials. The purpose of the thesis is to investigate how standards affect building and recycling practices in the Norwegian construction industry and how such standards act as barriers to sustainable development in the construction industry. As well as presents possibilities that could present itself in the future. The study provides insight into the interpretations that actors in the construction industry have of opportunities and barriers for the implementation of more environmentally friendly standards.
