Abstract: | The development of electricity market in Europe increases the number of energy exchanges between countries, this process rising new problems in the congestion management domain. The transfer capacity on one border is limited by the network conditions, the energy exchanges don’t have to jeopardize the system security. After the capacity on one border is established, it has to be allocated between the market participants.This paper presents several methods of capacity allocation established by The European Transmission Systems Operators (ETSO): pro-rata, first come first served, explicit or implicit bilateral auctions, market splitting, coordinated auctions.The methods are based on NTC (Net Transfer Capacity) determination or on physical flow margins, these last methods, like coordinated auctions, being more complicated but more accurate.The countries from South East Europe developed a working group who studies the coordinate auctions method and the ways of introducing it in a possible regional market.The paper offers a general view of capacity allocation methods, this being an important new activity of the Transmission System Operators in Europe. |
