As explained during Stakeholders meeting in Vienna on 21st 2010 of October and during Implementation Group meeting in Vienna on October 29th 2010, the tests have proven sufficient reliability. TSOs have published updated Auction Rules that entered into force in December 2010 on their website.
On November 29th 2010 first long-term matching process was executed according to the new rules and a day later, i.e. on November 30th 2010, short-term matching process for Business day December 1st was performed.
