A power generator had to reduce feed-in to prevent a blackout. A year-long dispute over money followed.
Wien. When talking about the volatility of the supply of wind or solar power, one usually has the image of a photovoltaic system in mind on a gloomy winter day or motionless wind turbines when there is no wind. But even if too much electricity is fed in at certain points and the grid is overloaded as a result, the power supply can collapse.
Such a scenario had to be prevented when Austrian Power Grid (APG), which operates Austria’s national electricity grid, gave the instruction on the evening of April 8, 2018 via the EVN subsidiary Netz Niederösterreich that in the next few hours the feed-in of wind power at a certain node should be reduced by 200 megawatts.
