Last Plant Standing: The Hidden Economics of Fossil Fuel Generators in a Decarbonizing Grid
The conventional assumption that grid decarbonization steadily diminishes the role of fossil fuel generators is being complicated by an inconvenient economic reality.

Understanding this paradox is essential for anyone modeling the true price trajectory of the US energy transition.
