Objectives of the price coupling algorithm
Article 38
1. The price coupling algorithm shall produce the results set out in Article 39(2), in a manner which: (a) aims at maximising economic surplus for single day-ahead coupling for the price-coupled region for the next trading day; (b) uses the marginal pricing principle according to which all accepted bids will have the same price per bidding zone per market time unit; (c) facilitates efficient price formation; (d) respects cross-zonal capacity and allocation constraints; (e) is repeatable and scalable. 2. The price coupling algorithm shall be developed in such a way that it would be possible to apply it to a larger or smaller number of bidding zones.
