Note: Scales have been truncated. These graphs show only non-universal ‘competitive’ supplies by universal suppliers in Germany in their own DSO area. The 2008 data are based on the most recent, preliminary data from the BNetzA’s 2009 monitoring exercise. Furthermore, the Commission compared energy charges — based on the best offer (lowest overall tariff) per DSO area — with the average energy charge in all German DSOs (8). As shown in Fig- ure 2 below, the results indicate a spread of around +20 %/–40 %, indicating significant differences be- tween competitive conditions in the different DSOs as a result of the differences in price among the German network areas.
