The electric power industry is undergoing rapid change due to increased renewable energy generation and distributed energy resources. In this environment, blockchain technology has become a promising tool to modernize energy markets and grid transactions. A blockchain is essentially a distributed digital ledger that securely records transactions without a central intermediary, enabling direct peer-to-peer exchanges and automated smart contracts. In recent years, many blockchain energy projects and pilot programs have tested applications such as local energy trading, real-time grid management through smart contracts, and tracking renewable energy credits.
