Electricity markets and auctions.
Among the questions that Pär Holmberg tries to answer with his research:
- What is the bidding behavior of producers in wholesale electricity markets and how is it affected by market rules and regulations?
- How are bidding affected by bottlenecks in the electricity grid?
- To which extent is financial contracts used in the electricity market and how do these affect the bidding process?
