Reading the actual study, it does seem their rank for "top 5% polluting" is total emissions. They do calculate relative intensity, as you say. But the ranking for plants with greatest emissions was done without regard for capacity. Also, the "73%" reduction would only be for GHG's from electricity-generation, not all sources. I mean, obviously coal is a pretty awful fuel from an environmental standpoint and it's good to quantify these things. Just reading these are hard when the authors didn't necessarily make 100% clear the last few tables.
