I did refer to the data, and that article gives about the same numbers. FERC and EIA are 'sibling' components of the Department of Energy, I suspect EIA's information on new generation comes directly from FERC. The article you link shows that wind and solar combined add up to a bit less than twice natural gas. This is because, as I said, the three dominant forms of new production (natural gas, wind, solar) added up to about one third each, with natural gas being the largest portion.
