Case Study: ENGIE achieves 80% penalty reduction with OutSystems

Energy Distributor Saves Hundreds of Thousands of Euros Automating Complex Business Processes

ENGIE, a global energy distributor, needed a way to standardize its highly complex nomination and balancing processes across 70 countries, each with different rules and legal entities. The company had been relying on manual Excel-based workflows and thousands of lines of XML code, which created high operational costs, maintenance burden, and penalty risk. ENGIE chose the OutSystems platform to build a rapid application delivery solution for this challenge.

Using OutSystems, ENGIE developed HARPON (HARmonized POwer Nomination) in just 28 weeks. The solution automated scheduling, balancing, and data handling across markets, helping reduce imbalances and penalties by 80% and save hundreds of thousands of Euros. It also delivered 90% productivity gains, cut training time from two months to two weeks, and reduced full-time employees by 25%, while giving ENGIE a scalable foundation for future growth.
