Germany's largest utility plans to spin off its conventional power generation, exploration and production units to focus on renewable energy. The fossil fuel units are restricted by German regulation as Germany moves to increase use of alternative solar and wind energy. The German government sees this as a positive step for energy transformation. German government support for green energy, including large subsidies, is resulting in a power surplus and lower prices for wholesale power. This makes traditional power plants unprofitable. In addition the ruble is negatively affecting Russian operations, Brazilian operations are unprofitable- these assets will be part of the fossil fuels unit, a kind of "bad bank" of assets, say analysts. E.ON shares went up by 4.3% on the DAX exchange, Dec. 1, 2014, showing positive investor perceptions of the move.
