Baseload capacity to become an anachronism

From an article by Jeff Siegel in the Baltimore Renewable Energy Examiner:

The chairman of the Federal Energy Regulatory Commission (FERC), Jon Wellinghoff, recently told reporters that he believes there my not be a need to construct a single new nuclear or coal-fired power plant, as renewables will be able to provide enough energy to meet baseload capacity and future energy demands.

While Wellinghoff is likely to catch a serious backlash from this one (especially from the coal and nuclear industries), the chairman noted that the technology for renewable energy has come far enough to allow this to happen, saying...

I think baseload capacity is going to become an anachronism. Baseload capacity really used to only mean in an economic dispatch, which you dispatch first, what would be the cheapest thing to do. Well, ultimately wind's going to be the cheapest thing to do, so you'll dispatch that first.

He also added...

...If you can shape your renewables, you don't need fossil fuels or nuclear plants to run all the time. And, in fact, most plants running all the time in your system are an impediment because they're very inflexible. You can't ramp up and ramp down a nuclear plant. And if you have instead the ability to ramp up and ramp down loads in ways that can shape the entire system, then the old concept of baseload becomes an anachronism.
