The state of the states: Data-driven analysis of the US Clean Power Plan

On August 3, 2015 the US Environmental Protection Agency finalized the Clean Power Plan (CPP) which aims to reduce CO2emissions from the electricity generating sector by 32% of their 2005 levels by the year 2030. With the rule now finalized, in order to understand how the impact of this will unfold, we need to understand the factors that may influence how the electricity sector evolves given the targets that must now be met. To both identify and understand these relevant factors, we have completed an analysis of US electricity generation data for the period between 2001 and 2014. The result is a detailed fingerprint of the sector per state based on monthly data at the resolution of individual generators. This analysis demonstrates that several “building blocks” or decarbonization strategies encouraged by the CPP are already being utilized in the period analyzed across US states, resulting in CO2emissions that have already dropped 12% in the period studied.
