Don't put words in my mouth. I never said batteries were cheap. I said wind is cheap. It's very very cheap. Both land-based and off-shore, but the $/MWh for land-based wind has fallen below natural gas and solar concentrator. Solar photovoltaic is roughly the same or a little cheaper than wind now, but the two can complement one another in regions that have reliable winds that come in just as solar is ramping down for the evening.
As to your battery question. Feel free to look it up if you want to know the economics of batteries, specifically when used for large-scale energy storage. There's not a lot of large scale sites up and running (there are a few notable ones). In the last two years come to a point where the prices for batteries have dropped enough that building more of them becomes attractive.
For us home users. The whole house batteries prices have dropped noticeably over the last few years. But having no battery and being grid-tied is cheapest, and I'd recommend that unless you have other reasons for a whole house battery than trying to time shift your solar or wind generator.
P.S. I was pretty deep into installing wind at home, but I backed out. so I'm solar only. Even though I have the paperwork approved for my site.
