Abstract

Recent advances in technology and the consequent decline in manufacturing costs are making energy storage systems a central element of energy and climate change policy debates across the nation. Energy storage systems have the potential to provide many benefits such as lower electricity prices at peak demand times, deferred or avoided new capacity investments, and reduced greenhouse gas emissions. Indeed, both federal and state policymakers are enthusiastically encouraging more energy storage deployment with the belief that energy storage systems will help reduce greenhouse gas emissions from the electricity sector by making intermittent and variable renewable energy resources such as solar and wind more attractive. This Article challenges the common assumption that increased energy storage will necessarily reduce greenhouse gas emissions. We first explore the conditions under which energy storage systems can cause an increase in greenhouse gas emissions contrary to the intent of policymakers. As policymakers start to rely more heavily on energy storage systems to achieve clean energy goals, this insight is crucial to inform stakeholders in the energy and climate policy debates. Next, we show that the current regulatory and policy landscape falls short of providing sufficient incentives for a desirable level of deployment of energy storage or sufficient safeguards to ensure that more energy storage deployment is indeed environmentally beneficial and economically efficient. Last, we suggest policy reforms that can correct these inefficiencies and discuss the jurisdictional roles that state and federal regulators have in implementing these reforms.
