The EPA’s Clean Power Plan recognizes and bolsters the current opportunity to reduce carbon emissions by transitioning United States electric grid from a fossil fuel dominant fuel mix to a balanced energy portfolio that includes higher penetration of renewable energy resources. The Clean Power Plan will require affected electric generating units (affected EGUs) within each state to reduce their carbon emissions, thus presenting the opportunity for utilities and states to shift towards sources that generate energy with little or no carbon emissions such as solar energy.

A new study from the National Renewable Energy Lab (NREL) finds that operating costs associated with additional power plant cycling caused by the integration of renewables to the grid are negligible when compared to fuel costs offset by displacing fossil fuels with renewable energy.
This assessment was prepared by North American Electric Reliability Corporation in its capacity as the Electric Reliability Organization1 and provides an independent view of the 10‐year reliability outlook for the North American BPS,2 while identifying trends, emerging issues, and potential risks.
