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.

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
