Regional Interconnection & Power Exchange

  • Argonne applied GTMax to analyze hourly operation of a regional electricity market for Southeast Europe and identify economic benefits of regional trading for USAID.

GTMax - Generation and Transmission Maximization Model

Argonne National Laboratory developed GTMax to study complex marketing and operational issues in today's restructured power systems.


GTMax helps utilities maximize the value of their system assets, taking into account IPP agreements, power and energy transaction opportunities, and limitations of energy and transmission resources. 

GTMax simulates regional or national generation and transmission systems. The software maximizes net revenues while ensuring that market transactions and system operations are within physical and institutional limitations.



    Generation and Transmission Investment

  • PwC and MWH applied GTMax for the Southeast Europe Generation Investment Study conducted for the EU and World Bank.

  • Fichtner used GTMax in preparing the CAREC Regional Power Sector Master Plan for ADB.

    Electric Market Analysis 

  • US utility uses GTMax to fine tune hourly resource generation patterns, spot market transactions, and energy interchanges. 

  • Philippine merchant power company uses GTMax to support energy trading decisions.

Adica is worldwide distributor of GTMax.  Clients include electric utilities, transmission companies,  regulatory bodies, research institutes and consulting firms.


Upon completion of a technology review that considered suitability and cost-effectiveness of the software solution, maintenance,  training and staffing, USAID procured 15 GTMax licenses for utility companies in seven countries. 

GTMax is licensed for use by clients in over 20 countries and has been applied for studies funded and managed by the ADB, European Union, JICA, USAID and the World Bank.
