Already happens, fairly regularally in CA based on news reports.  
Midday wholesale electric rates often go negative (electricy suppliers 
will pay you to use electricity).

This is the current kink.  There is often enough abundance midday that 
the price is negative (or generation is curtailed because it has no 
sink into which to go).  Nighttime, however, is a very different story.

Reality is, given current tech., pricing, and installed base, some form 
of "base generation" using existing tech.  (coal, gas, nuclear, hydro) 
is required to last through the nights (and the 'days of overcast' that 
sometimes happen).  Only two of the four are 'carbon free' and only one 
is suitable for use in geographic areas without significant volumes of 
water running downhill.
