Fra Zerohedge:
A stormy weekend led to free electricity in Germany, as Bloomberg reports wind generation reached a record, forcing power producers to pay customers the most since Christmas 2012 to use electricity.
Power prices turned negative as wind output reached 39,409 megawatts on Saturday, equivalent to the output of about 40 nuclear reactors.
To keep the grid supply and demand in balance, negative prices encourage producers to either shut power stations or else pay consumers to take the extra electricity off the network
