Accommodating High Percentages of Wind and Solar
Germany had not installed adequate storage to accommodate high percentages of wind and solar power and in 2012 is exporting peak generation to neighboring countries.
Approximately 9 GW of photovoltaic plants in Germany are being retrofitted to shut down if the frequency increases to 50.2 Hz, indicating an excess of electricity on the grid. The frequency of the grid is available on the Internet, and is unlikely to reach 50.2 Hz during normal operation, but can if Germany is exporting power to countries that suddenly experience a power failure, as happened in 2003 and 2006.

Famous quotes containing the words high, wind and/or solar:
“Both cultures encourage innovation and experimentation, but are likely to reject the innovator if his innovation is not accepted by audiences. High culture experiments that are rejected by audiences in the creator’s lifetime may, however, become classics in another era, whereas popular culture experiments are forgotten if not immediately successful. Even so, in both cultures innovation is rare, although in high culture it is celebrated and in popular culture it is taken for granted.”
—Herbert J. Gans (b. 1927)
“The wind is old and still at play
While I must hurry upon my way,
For I am running to Paradise;
Yet never have I lit on a friend
To take my fancy like the wind
That nobody can buy or bind....”
—William Butler Yeats (1865–1939)
“The solar system has no anxiety about its reputation, and the credit of truth and honesty is as safe; nor have I any fear that a skeptical bias can be given by leaning hard on the sides of fate, of practical power, or of trade, which the doctrine of Faith cannot down-weigh.”
—Ralph Waldo Emerson (1803–1882)
