Solar Eclipse 20.3.2015 on COSMO-7 Domain from Oliver Fuhrer on Vimeo.
"In the UK, more than half of the solar generation could be lost. But this will be largely offset by the drop in demand caused by people stopping what they are doing for a few minutes to wonder at the astronomical event. If it is cloudy, as currently forecast, then demand will increase but the drop in power, and thus the effect on the grid, will be negligible." (Karl Mathieson, The Guardian, today.)
