TEP required member states to liberalize the power markets while RED set incentives to pick-up champions. The call for opinion on the ETD intends, presumably, to boost EU common market, while the RED and other policies are fragmenting it.
Energy industry is par excellence a major industry. Few businesses have larger money flows than energy. Thus, it is not unnatural that it draws attention of powerful people, public and politics. In 2000s Europe experienced major policy craze with renewable energy that is still riding the waves of popularity, albeit with first subtle hints of realism.
Since the current situation on European energy market is a result of poorly designed market distortions, we should ask ourselves whether strengthening of the targets is a step in the right direction.
