What's New - October 2025

Each month, we highlight the latest enhancements across the PLEXOS® platform to help you model faster, plan smarter, and collaborate more effectively. In the October 2025 update, you’ll find new features in PLEXOS® 11.0 R05, expanded PLEXOS® Cloud workflows, and new PLEXOS® Playbooks and datasets to help you get started faster and deliver clearer results. 

In this What's New:


PLEXOS®

PLEXOS 11.0 R05

The latest version of PLEXOS® 11.0 R05 is now available to download from the customer portal or access directly in PLEXOS Cloud. 

This release includes several important updates to improve modeling accuracy, flexibility, and performance across key workflows: 

Enhanced cloud integration and performance 

  • Improved integration with PLEXOS Cloud enhances the user experience within PLEXOS Intelligence  
  • Optimized formulation of unit commitment (UC) constraints for generators improves simulation speed and reliability. 

More flexible maintenance scheduling 

  • Maintenance events can now be scheduled based on cumulative operating hours or the number of generators starts. 
  • A new “components” class enables alignment of maintenance timing with spare part availability. 
  • Maintenance constraint formulation has been refined to reduce runtimes in complex models. 

Gas system enhancements 

  • New properties have been added to the gas module to make constraint setup easier and more precise. 
  • Multi-banded efficiency curves are now supported for gas plants, providing greater accuracy when modeling fuel use and system performance. 

Water system modeling updates 

  • Built-in constraints for water plants simplify setup and allow for more streamlined, maintainable models. 

Fixes and stability improvements 

  • The release includes corrections to formulation logic, user interface behavior, and reporting outputs. 
  • Error handling and validation have also been improved to support faster troubleshooting and clearer diagnostics. 

Several enhancements in this release were inspired by feedback and ideas submitted through Xchange, a place for users to share ideas, ask questions, and exchange insights about using PLEXOS and other products. Thank you to everyone who contributed. 

Full details on what’s changed from PLEXOS 11.0 R04 are listed in the revision notes, available in the Customer Portal.

PLEXOS® Intelligence

PLEXOS Intelligence continues to expand its capabilities to help users identify issues faster and extract insights more easily. You can now view study version changes at a glance and detect infeasibilities earlier in the modeling process, reducing time spent on manual troubleshooting and allowing you to focus on scenario analysis. 

The new smart query builder offers two flexible ways to interact with your data: use natural language for fast results or write in SQL for full control and precision. Both options support dashboard creation and output analysis without requiring advanced coding. 

You can: 

  • Compare actual market data from Datahub with forecasted scenarios 
  • Explore model outputs collaboratively with your team 
  • Export visuals for presentation directly from dashboards 

These features support real-time insight generation and faster decision-making across your planning workflows.

PLEXOS® Cloud Enhancements

This release delivers a wide range of improvements to the PLEXOS Cloud platform, supporting better collaboration, faster analysis, and more flexibility across simulation workflows. Whether you're building dashboards, managing datasets, or coordinating study versions across teams, these updates are designed to streamline your experience from end to end. 

  • Analytics 

    • Build dashboards with a mix of charts, grids, and pivot views 
    • Compare multiple solutions side by side 
    • Add nodal analysis layers for congestion insights 
    • Create clear visualizations for stakeholders with new formatting and scaling options 

These features support more efficient analysis and communication of results. 

  • Simulation 

    • Pre- and post-simulation tasks can now be set directly in the run panel 
    • Re-reporting lets you reuse solution files without running the entire model again 
    • Distributed runs now include memory controls, so larger studies finish with fewer interruptions 

These updates give you more control over how and when simulations run, reducing wait times for results. 

  • PLEXOS® Cloud Excel Add-in 

    • Higher row limits for queries mean you can bring more results into Excel 
    • Custom columns and schema validation improve accuracy 
    • Easier attribute selection makes setup quicker 
    • Reporting fields improve visibility across studies 

This update helps you keep Excel workflows connected to PLEXOS without manual workarounds. 

  • Study management and storage 

    • Preview and download earlier study versions to track progress 
    • Connect external storage directly with CLI and Datahub integrations 
    • Start new studies with built-in PLEXOS Playbooks 

This makes collaboration easier by keeping all your study history and assets in one place. 

  • Central License Manager 

    • Standardized license refresh times make user management simpler across desktop and cloud

PLEXOS® Playbooks

PLEXOS Playbooks give analysts, traders, and planners a complete, simulation-ready modeling package, featuring curated datasets, prebuilt scenarios, simple editing features, interactive dashboards, automated workflows, and embedded PLEXOS Intelligence for AI-enhanced assistance. 

PLEXOS® Playbook for India Renewable Energy–Round-The-Clock (RE-RTC) (beta) 

This PLEXOS Playbook enables users to easily and effortlessly optimize the configuration of renewable energy portfolios to meet the obligations of Round-the-Clock (RTC) renewable energy contracts in the India energy market. Users can easily configure the options, costs and properties for the generation and storage, and define the demand obligations and other conditions of the RTC contract. Optimized portfolios are summarized in easy-to-read asset, operational and financial reports and charts. 

PLEXOS® Playbook for AEMO ISP 

Developed to work with AEMO’s public Integrated System Plan (ISP) datasets, PLEXOS Playbook for AEMO ISP provides out-of-the-box visualization and reporting capabilities.  PLEXOS Playbook for AEMO ISP provides a quick and easy way for modelers to get started using the AEMO ISP 2024 datasets. The consolidated model conveniently combines all three PLEXOS models for each climate scenario into a single study, allowing for easy comparisons. A companion Excel workbook provides pre-made visualizations that recreate key charts from the ISP report.
