Can validate. The problem with electricity is that there is no large scale storage like there is for other forms of energy like NG and Crude. Until someone comes along and figures out how to store electricity, this will continue to cause grief to power companies. Power plants are really just options, if the price per kWh is at a certain point then it makes sense to spin up or take down a plant and generate power. Adding a bunch of highly variant generation to the grid can make the market more volatile since there could be a lot of up and down with generation facilities.[0]

That said, there will be teething pains but this is a net positive thing that is happening. Growing up I lumped solar into the perpetual 10 years away category. It looks like I am going to see solar be competitive after all.
