I viscerally hate this title, because the top 5% of power plants probably also account for >50% of electrical generation, and the entire exercise is dominated by how small of a plant counts for the statistics. If all the portable generators sitting unused in people's garages counted, I bet that 0.1% of "power plants" would be responsible for 99% of emissions, which would make a great headline but still wouldn't tell you anything meaningful about the world.
I would love to know about how efficiency varies with plant size (are bigger plants more efficient?) but this study is _mostly_ just stating that bigger power plants produce more emissions in absolute terms, which should be obvious to pretty much anyone.
