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.
