Adaptation of the Exfact model to fifteen-minute intervals

J. García-González A.F. Oviedo-Gómez

June 2025 - September 2025

Funding entity Endesa Medios y Sistemas S.L


The EXFACT model is part of the EXCOM-EXLA family. Its purpose is to ensure the feasibility of the schedule following the clearing results of the day-ahead market and the secondary regulation band market for Endesa’s hydro portfolio. It includes the highest possible level of detail regarding all the hydraulic constraints to be met, as it is the last model run before energy delivery and serves as the basis for the energy-price offer curves used in subsequent markets (TERRE, Tertiary, and MIC).The general objective of this project is to adapt EXFACT to operate with fifteen-minute granularity in order to comply with the new rules of the electricity market.


Layman's summary: The general objective of this project is to adapt EXFACT to operate with fifteen-minute granularity in order to comply with the new rules of the electricity market.
