Transmission System Operators (TSOs) from five countries: Belgium, France, Germany, Luxembourg and Netherlands, decided in June 2007 to establish a shared auction office.
With the formal incorporation in October 2008 in Luxembourg, Capacity Allocation Service Company for the Central West Europe (CASC-CWE) a common, regional cross border electricity market was established.
In the Central East European market area TSOs decided to establish a common auction office as well. The TSOs from Germany, Austria, Czech Republic, Slovenia, Hungary, Slovakia and Poland, settled Central Allocation Office (CAO GmbH) in Freising, Germany.
CAO's first auctions started in October.
TSOs of Switzerland, Austria, Slovenia, Italy and Greece joined CASC-CWE S.A. which becomes CASC.EU S.A. raising the number of shareholders to 14.
Merger of CAO GmbH and CASC.EU S.A. constitutes a new company.
