About this time last year, I published an article on Hydro Review where I asked: “Who will build the first new pumped storage hydro in the U.S.?”

In that article, I didn’t really provide an answer to the question. I did list the three projects I saw as the front runners, based on them having operating licenses from the Federal Energy Regulatory Commission: 1,300 Eagle Mountain in California, 400 MW Gordon Butte in Montana and 393 MW Swan Lake in Oregon. And I included the 1,200 MW Goldendale project in Washington in the honorable mention position.
