Recently, the energy market is going through drastic changes with the launch of a new climate regime and the advent of the Fourth Industrial Revolution era. Amid these changes, many countries worldwide are strategically pushing for digital transformation to address various issues arising from the pursuit of energy conversion policies. As defined by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety of Germany (BMU), energy transition refers to the shift to a sustainable economy through renewable energy, energy efficiency, and sustainable development, and its ultimate goal is replacing coal or other nonrenewable energy sources entirely with renewable ones.
Thus, energy transition is the shifting of centralized nuclear and fossil-based energy systems into decentralized renewable energy-based systems. However, the critical issue behind it is to expand the use of renewable energy and reduce energy consumption through energy efficiency. As such, energy transition can be more efficient through digital transformation, which combines technology and ICT in the field of electrical energy. Therefore, the present publication examines the various cases of the digital transformation of utilities and identifies the implications of digital transformation in the transition to clean energy. Moreover, ISGAN Annex 4 aims to convey some messages, such as what the digital transformation means in terms of transition into smarter energy, its potentiality, and the most pressing challenges, to policymakers and related industries.
