Distributed Energy Storage

Electricity storage is no longer merely a technological innovation; it is increasingly a subject of legal and regulatory contestation. As distributed energy resources (DERs) expand across jurisdictions, both utilities and end-users depend on electricity storage to manage intermittency, enhance grid stability, and support decarbonization. Yet, despite its rising importance, the legal and policy frameworks governing electricity storage remain underdeveloped, fragmented, and often fail to adapt to the complexities and roles storage systems play in modern grids. This chapter presents a thematic legal and policy analysis of electricity storage, examining three distinct models: standalone utility-scale storage, behind-the-meter consumer and prosumer storage, and storage integrated within DER systems. Each model represents points of integration within energy systems, presenting unique legal and regulatory challenges that require tailored solutions. Key challenges include regulatory ambiguity, licensing, and interconnection barriers, data protection, liability, market access, and classification of storage assets. The chapter distinguishes between the legal treatment of storage operated by distributors (such as utilities and grid operators) versus consumers, analyzing how each model fits within evolving electricity market structures. While the chapter adopts a global comparative approach, it draws lessons from select Middle East and North African (MENA) countries—United Arab Emirates, Oman, Morocco, and Egypt—to highlight innovative approaches and persistent barriers in emerging markets. These examples underscore the importance of legal clarity, integrated infrastructure planning, and supportive investment frameworks in unlocking the potential of electricity storage. The chapter concludes by proposing legal and policy recommendations to facilitate effective integration of electricity storage into distributed systems.
