VDEW's claim was general, that electricity prices increase due to state surcharges (the title of the linked press release translates to: "State makes electricity bill more expensive"). That they grew is not a question, how different parts grew matters only inasmuch as VDEW was 'creative' in its interpretation of statistics; what matters is that they again chose to emphasize the state part, while most of the increase this year was from them - and did so simply by not publishing the complete statistics.

Anyway, here is the structure of the German private electricity bill, from the point of view of traditional producers/grid owners:

1. Production price
   
2. Grid charge
   
3. (Profit)
   
4. Coupled power generation/heating surcharge (granted by a newer law to promote energy efficiency, but this too goes into the traditional producers' pockets)
   
5. Regenerative energy feed-in tariffs (grid owners pay the windmill etc. owners, then spread the costs among consumers; for consumers, the extra cost is the amount by which tariffs exceed market prices, but of course all of it is money lost for traditional producers)
   
6. Concession charge (paid to cities and communities)
   
7. Environment tax (at a rate fixed to consumption in kWh)
   
8. VAT (a fixed percentage, now 16%, of the sum of the previous)
