The country's electricity supply is greater than the actual demand situation, will lead to this weekend's German electricity prices from mid-October 30 euros / MWh, fell to 0 euros / MWh or less. Germany has had a negative price in a given period of time, but this will be the first full day average price of electricity is negative.
Wind power installed capacity of the country accounted for one-third of the peak to meet half of Germany's electricity demand
Such a huge wind power equivalent to about 40 nuclear power plant total power generation, to meet more than 50% of the German national electricity demand.
Due to the lack of proper large-scale power storage, when the wind power is at peak, the German power suppliers to meet people's electricity demand at the same time, it is difficult to maintain a corresponding balance of power supply. A negative price means that the power supplier must shut down the power station to reduce power supply, or to "overwhelm" the user, to encourage it to increase the electricity consumption on the grid.
As of June this year, Germany's onshore wind farm has accounted for one-third of Germany's national installed capacity, and according to the German Wind Energy Association is expected this year, new installed capacity of wind power will rise 9%.
