REPLY: Enel Improves Maintenance Work Efficiency with Quantum-Inspired Algorithms

TURIN, Italy–(BUSINESS WIRE)–Reply today announced that it has implemented a Quantum Inspired Algorithm for Enelone of the world’s leading operators in the power generation and renewable energy sector. This innovative solution allows Enel to quickly identify the optimal allocation of maintenance activities for the operating units distributed in the areas where it operates.

For Enel, which claims a presence in more than 30 countries worldwide, a network of more than 2.2 million kilometers and 74 million end users, it is essential to coordinate teams as well as allocation and planning. the objectives of the operational units spread over the different territories in order to guarantee the highest level of service to its customers. Hence the need for operational planning that is as efficient as possible.

The solution developed by Reply is based on the mathematical model QUBO (Quadratic Unconstrained Binary Optimization) and can be executed efficiently by quantum hardware, known as Quantum Processing Units Where QPUsas well as by classical hardware, known as Graphics Processing Units Where GPUs. Enel’s cloud infrastructure, based on Amazon Web Services, of which Reply is a Premier Level Consulting Partner, includes both types of hardware.

Harnessing the maximum potential of GPUs has been made possible through the accelerator MegaQUBOa software solution developed by Data Reply to accelerate the implementation of Quantum Inspired Optimization projects. MegaQUBO is a solution certified by Amazon Web Services for use on the AWS Cloud, through the “FTR – Foundational Technical Review” process which ensures that the software adheres to AWS architectural best practices.

In addition to identifying the optimal distribution of activities, the algorithm created for Enel is also able to calculate the optimal planning of routes to reach workplaces by minimizing travel times and distances and maximizing the time available for actual maintenance work. This results in a increase sensitive productivity and an reduction substantial from costs ofexploitation and of theenvironmental impact corresponding.

“Quantum computing makes it possible to solve challenges that were considered insurmountable just a few years ago,” comments Filippo Rizzante, CTO of Reply. “As we have been able to successfully demonstrate through our experience with Enel, the use of quantum algorithms to solve optimization problems makes it possible to obtain significant advantages not only in terms of the quality of the results but also in the reduction in processing times, so at Reply we are closely exploring different areas where we can exploit the potential of quantum computing to obtain key information from extremely large and constantly updated databases.”

“The need to implement optimization strategies over increasingly large geographic areas has increased the complexity of the problem correspondingly, to the point of requiring a new and innovative approach,” explains Fabio Veronese, Head of Infrastructure & Networks Digital Hub at ENEL. “The Quantum Inspiration approach implemented with Reply has delivered significant, concrete results in the field and is applicable to both known problems and new business contexts.”
