Abstract Quantum computing and quantum-inspired technologies are set to significantly impact the energy sector, enhancing optimisation and simulation processes to enable studies that cannot be performed today. At Siemens Energy, our studies have shown potential to address complex challenges in grid management, power distribution, and scarce resource allocation. One of the important examples of where quantum computing holds promise is in the field of optimisation, where physical systems are used to find low energy (i.e. high quality) states (i.e. solutions) to systems that could support many configurations (i.e. combinatorial optimisation problems). The integration of quantum computing into the energy industry promises to deliver improvements in several fields, including cost reduction, increased system reliability, and importantly to be able to make better use of existing resources. Currently in the early stages of research and development, Siemens Energy’s work is showing that combinatorial optimisation problems are all around us in the energy sector. Practical quantum-inspired and hybrid approaches can be used today to solve some of these problems and bring benefits in areas which would have previously not employed optimisation traditionally. This gives us the opportunity and tools to attempt new and innovative approaches to decarbonisation and attempt previously insoluble challenges in the industry.
