Interesting article below about pumped water storage. Probably EV advocates don't know that Virginia has the worlds largest battery, well sort of: we have the biggest pump water facility. The orig intent I think was to store nuke and coal nighttime elec loads from WV (coal) and VA (nukes). Apparently California converted an old mine to pumped water storage, and now that's a hot topic here as we've passed a resolution to pursue that in Virginia. In Virginia push for pumped hydro storage, questions arise about viability | Southeast Energy News
Yes worth a day trip to go out there and see it someday...pretty much in the mountains off I-81 looks hard to get to. More popular is the Smith Mountain Lake dam and that we have been to and I have my own photos like the one in the article. Virginia only has 2 natural lakes, one being the Great Dismal Swamp. So every other lake is man-made.
