  Renewable energy sources (RES) are among the most popular emerging energy
resources during the past two decades. Many countries have introduced various
energy policy instruments, such as renewable energy certificates (RECs), to
support the growth of RES. RECs are tradable non-tangible assets, which have a
monetary value. Tracking and certification of the origin of an energy resource
regardless of its type (e.g., a conventional power plant or RES) is a critical
operation. In addition to the certification of origin, trading transactions are
needed to be performed using a secure method. Energy industry participants need
to secure the data and applications related to RECs. Distributed ledger
technology (DLT) is a perfect framework that can support such REC
functionalities. This paper addresses the cybersecurity aspects in REC trading
using Blockchain and a distributed ledger technology, considering detailed
cybersecurity perspectives.
