Congestion management in the nordic electricity market

Coauthors: Mette Bjørndal, Victoria Gribkovskaia


Presently in the Nordic day-ahead market, zonal pricing or market splitting is used for congestions between a predetermined set of price areas. Intra-zonal congestion is resolved by counter trading or redispatching in the regulation market. We study aggregation choices when simplifying nodal prices into zonal or area prices. We discuss two different aggregation concepts, which we call economic and physical aggregation, and their relation to optimal nodal prices. In a model of the Nordic electricity market we consider an hourly case from winter 2010 and present analyses of the effects of different congestion management methods on prices, quantities, surpluses and network utilization.
