The energy industry is undergoing a revolution, and new grid models are emerging with distributed energy resources (DERs) combined with renewable energy systems leading the way. As corporations and the public sector move towards Zero Carbon, distributed generation (DG), from wind farms to solar power to fuel cells, continue to play a growing role in energy system design and operation. These technologies present both daunting challenges and valuable opportunities in rethinking the economics and management of energy systems. Digitization and Industry 4.0 are transforming how the energy business is run.
