IEEE 2418.5-2025

New IEEE Standard - Active. Blockchain/distributed ledger technology, referred to as blockchain/DLT, is a proven technology in industry and, though newer to applications in the energy industry, is well-positioned to become a critical component of this evolving electrical system. blockchain/DLT can provide transparency and traceability within energy markets and distributed system operations, reduce error and processing inefficiencies between the multiple parties engaged in interconnected grid management, and offer a path to automation of the grid through the use of smart contracts. This guide provides an open, common, and interoperable reference framework model for distributed ledger technology (DLT ) such as blockchain in the energy sector. This guide also serves as a guideline for blockchain/DLT use cases in the electrical power industry, creating a guide for a reference architecture framework, including interoperability, terminology, functionality, and system interfaces.
