Transitional regulations for prequalification for tertiary control
Within the framework of the working group Balancing Energy, it was agreed that plants that have participated in tenders for minute reserve organised by APCS up to 30 September 2011 will be required to complete
temporary prequalification for tertiary control at APG within the framework of an accelerated process. This temporary prequalification is valid until 31 December 2012. As on several occasions in the past, we once again draw your attention to the fact that a list with the relevant plants must be forwarded to APG by Friday 18 November 2011 at the very latest. The registered plants that meet the specified criteria will receive a temporary prequalification from APG to facilitate continued participation in the tenders.
