August 2017 was characterised by the second tender for wind-onshore, the subsequent discussions about citizen energy companies and the significantly decreased price level. Despite the summer break, electricity prices have been increasing at the long end of the curve.
On Saturday, August 19th 2017, as well as on Sunday, August 20th 2017, a high production of variable renewable energies hit a low demand. The primary causes of this are the weekend and the holiday period. On both days, negative prices occurred at noon over a maximum period of five hours, so that the production was not affected by § 51 EEG 2017.
