SOLARMAX and Power Interruptions

I recently saw the documentary Solarmax at Portland's OmniMax theatre, which
was very interesting (not too mention a great ride in omnimax theatre!).
The documentary on the sun outlined the impact of solar flares, especially
the ones that occur every 11 years when the sun reverse rotation. The last
one, 11 years ago, affected power grids and satellite systems (then in
toddler stage). Does anyone have any information on the expected impact of
this year's solarmax on power grids and satellite communication? Or was the
documentary more hype than fact?
