Market Specific News and Its Impact on Electricity Prices – Forward Premia

This paper studies the impact of market specific news on the short-time forward premia on the Scandinavian electricity market. I show that the short time premia between the day-ahead and intra-day electricity prices on the Scandinavian market can be explained by the arrival of news specific to the power market. By exploring the types of news I indicate that production failures shape the premia. Production disruptions in coal-powered units are most frequent and have the greatest effect on the differences between the day-ahead and intra-day prices.
