Electrical grids in Europe claimed success on Friday in managing the unprecedented disruption to solar power from a 2-1/2-hour eclipse that brought sudden, massive drops in supply.
Germany, Europe’s biggest economy, at the heart of the event, boasts the world’s biggest solar-powered installations, which last year supplied 6 percent of national power requirements.
The initial 13 gigawatts (GW) drop in Germany was less than operators had feared and they were able to draw on alternative power sources including coal, gas, biogas and hydroelectric energy pumped from storage.
Grid spokespeople said control rooms were tense. “The mood is concentrated but confident that it will go smoothly,” said Andreas Preuss, spokesman of TenneT peer Amprion, which operates the longest network inside Germany.
