This chapter discusses the combination of community energy and digitalisation. From a historical and futuristic perspective, the needs and demands are discussed in a rapidly changing energy and communications landscape. The chapter explores how the proliferation of distributed energy resources and the changing role of the consumer are changing the entire nature of the industry. Ideas are presented for integrating the desire for autonomy and community exchange with the needs of an optimised system, and how these developments are driving change and creating new market opportunities. This chapter further assesses the role and opportunities blockchain and distributed ledger technology take in a traditional industry that must always keep the lights on. We identify the Internet as a key enabler of change that can be seen as a grid of data that supports the increasing complexity in the energy industry. The concept of the ‘energy internet’ is used in this context to enable local, national and international balancing of electricity networks. Finally, we highlight the opportunities presented by local energy markets and discuss the risks if consumers are not adequately protected from energy system vulnerabilities. The technical and legal opportunities for prosumers to become local, self-balancing, holons that are part of the market may result in increasing reward systems when they contribute to electricity grid balancing services.
