The reliability of the electric grid will not necessarily suffer with the increasing retirements of traditional baseload power plants, according to a new policy study from think tank R Street Institute. While dependable and dispatchable power is “essential” to grid reliability, those characteristics come not only from traditional sources like coal and nuclear plants, but also from renewable sources of power,¬†according to the study’s author, Electricity Policy Manager Devin Hartman.
