All RECs Are Local: How In-State Generation Requirements Adversely Affect Development of a Robust REC Market

Abstract

While most U.S. states have now adopted renewable energy portfolio standards, most also require a certain percentage of such generation to be “home grown.” These requirements lead to volatile and reduced-value markets for renewable energy credits and ultimately increase the cost of renewable energy. A review of the requirements suggests that either national or regional markets be fostered to reduce such adverse impacts of the requirements.
