Power company just built a solar collector to pre-heat water going into the powerplant.

That's one use that sounds like it could actually be cost effective. (Although they might just be doing it for tax credits). You have the power plant infrastructure anyway, so you aren't building generators and such just to handle the solar heated water. When the sun shines, you don't have to make it heat the water up quite as much as you would have to in order to run 100% of solar heat, so the part of the plant with the sun heating water can be cheaper than it would have to be in a 100% solar plant. And when the sun doesn't shine you just burn gas or coal or whatever the plant normally uses.
