Open Generation, Storage, and Transmission Operation and Expansion Planning Model with RES and ESS (openTEPES)

Simplicity and Transparency in Energy Systems Planning

The openTEPES model has been developed at the Instituto de Investigación Tecnológica (IIT) of the Universidad Pontificia Comillas.

The openTEPES model presents a decision support system for defining the integrated generation, storage, and transmission expansion plan (GEP+SEP+TEP) of a large-scale electric system at a tactical level (i.e., time horizons of 10-20 years), defined as a set of generation, storage, and (electric, hydrogen, and heat) networks dynamic investment decisions for multiple future years.

It is integrated into the open energy system modelling platform, helping model Europe’s energy system.

It has been used by the Ministry for the Ecological Transition and the Demographic Challenge (MITECO) to analyze the electricity sector in the latest Spanish National Energy and Climate Plan (NECP) 2023-2030 in June 2023.
