Nexus-Strategy is an online collaboration platform for water-energy-food-environment analysis and planning. By jointly simulating power systems and river basins, it helps explore options and make better investment and management decisions . WEFE models are built, updated, run, visualized, and shared in a web interface.

Use cases

Assessing interventions (new infrastructure and policies) in WEFE nexus systems.


Multi-sector impact evaluation of new infrastructure and new infrastructure operations.


Climate change impact assessments.


Integrated climate change adaptation and mitigation studies.


Easy-to-use graphical user interface for water-energy-food-environment system modeling.


Cloud computing to securely manage large datasets and models on Microsoft Azure.


Track system evolution over space and time (flows, storages, abstractions, transfers, etc.) and report on system performance (reliability, resilience, vulnerability, cost, etc.).


Share models and results in a secure and controlled way within teams and with decision-makers and stakeholders.


Simulations use open source Python models (‘Pywr library).


Data is managed by Hydra Platform, an open-source data manager.


The open-source Pynsim library is used to connect models when needed.
