Note that the "base load" argument from the coal industry (and some nuclear zealots) is utter nonsense aimed a people's ignorance, coal has always relied on other technologies to keep the lights on. The demand curve of a city is not flat, to match it coal requires hydro to store energy when the plant exceeds demand, and fast switching gas turbines to compensate when "stored hydro + base load" is not enough. Also a coal plant will be down for 2 months a year for maintenance, meaning to get the full output of 6 plants you need to build and operate 7. Solar has a fantastic advantage in summer since air-conditioning is the drain, not much good in winter when the air conditioner goes into reverse.
Many people will be able to see all this clearly manifest itself in their electricity bill as peak/off-peak rates.
