March 2026 - April 2026

Funding entity Endesa Medios y Sistemas S.L, Endesa S.A.


This project is part of the professional services provided to Enel-Endesa within the EXCOM model. The objective is to analyze the impact of resolving technical constraints due to insufficient upward reserve.


Layman's summary: The EXCOM model is used to determine the hourly scheduling of all thermal, hydropower, and renewable generation assets of Enel-Endesa in Spain and Portugal. The Technical Constraints Market, managed by Red Eléctrica de España, ensures—among other analyses—that there is no insufficient upward reserve. The objective of the project is to analyze how to incorporate this feature of the technical constraints market into the EXCOM model.



Techniques employed: Mixed integer linear programming
