PlanOS grid planning software
Integrate your grid planning like never before—the comprehensive software platform to confidently plan for a more reliable, resilient, and stable energy system.
Transforming grid planning
The PlanOS software platform offers a holistic approach to planning your energy system’s most pressing challenges. With the option to augment your modeling with GE Vernova’s robustly-mapped power system dataset, you can enhance your analysis and accelerate model development.
Your unified dataset model can seamlessly flow between native single- or multi-function analysis—enabling a truly integrated experience.
In the 1960s, the tools our Engineers needed to understand and operate complex electric grids didn’t exist. So, they built them.
Early simulations explained issues and directly led to innovations in generator protection.
Using our models, planners proved wind could meet 10% of system capacity without compromising reliability.
We didn’t set out to sell this grid planning software, but as utilities began requesting access to our tools, we responded.
What started in New York now supports planners worldwide as they modernize the grid.
The origin of PlanOS
PlanOS was built out of necessity by power system engineers tackling real-world challenges. In the 1960s, our engineers faced a significant challenge: the grid was becoming increasingly complex, but the tools to understand and operate it didn’t exist. So, we built them.
Early models identified the cause of twisted generators and helped develop solutions to mitigate future issues. Over time, the tools evolved to become more advanced, supporting everything from reliability planning to renewable energy integration. As utilities asked to use them, we shared these resources first through time-share systems and later through local installations. What began in New York has expanded into a trusted platform used by planners worldwide. Today, that legacy lives on in PlanOS: a purpose-built software developed by decades of hands-on experience and real-world planning needs.
PlanOS' functions
The PlanOS platform brings together GE Vernova’s decades of proven planning software tools (Production Cost, formerly MAPS*; Resource Adequacy, formerly MARS*; Power Flow, formerly PSLF*) and newly added Capacity Expansion into one powerful interface. PlanOS utilizes one shared dataset to seamlessly transition between analyses, like production cost, resource adequacy, and power flow, without the need for third-party add-ons.
This coordinated and holistic approach to analyzing a power system helps you break down traditional grid modeling silos and help you with your Integrated System Planning analysis.
The energy grid is changing fast, driven by electrification, AI, and renewables. Discover how Integrated System Planning helps utilities and operators respond to evolving demands, meet regulatory expectations, and plan for a reliable energy future.

Frequently asked questions
With the growth of inverter-based resources and the increase in variable loads on the grid, it’s critical for system planners to consider more comprehensive planning approaches to help identify and solve issues holistically. Integrated Systems Planning is an approach to energy planning that considers all aspects of an energy system aiming to improve the system for cost-effectiveness, sustainability, and reliability by coordinating them together, rather than planning each element separately. This holistic approach provides an improved understanding of resources and their performance while aiming to ensure cost-effective reliability.
Traditionally, the analyses that feed into system planning, like resource adequacy, cost of production, and power flow, are conducted in silos and often rely on different data models, assumptions, and factors. This traditional siloed approach to system planning may result in inaccurate or disassociated insights.
GridOS enables a unified dataset model for the near or real-time operations of the power grid. PlanOS utilizes your dataset focused on long-term planning analysis.
As GE Vernova continues to provide solutions that help you stay ahead of grid complexity, both in terms of operations and planning, the thoughtful architecture of our solution is meant to provide the fidelity of unified data that is appropriate for the context of analysis you need. Spend your time where it matters, planning the grid of the future—not connecting disparate data sets and building multiple data models.
PlanOS is the platform in which your unified dataset model can seamlessly flow between native single and/or multi-functional analyses. Previously known as PSLF, MAPS, and MARS, now known as Power Flow, Production Cost, and Resource Adequacy, PlanOS is built on the industry-proven algorithms you have grown to trust with expanded capabilities and soon a refreshed user interface. With the ability to utilize robust grid models of over 50+ countries developed and maintained by GE Vernova (an industrial and software company–we understand the hardware) you can enable your journey even faster. Contact GE Vernona’s Consulting Services to learn about our high-fidelity models.
PlanOS is not just a new user interface, nor is it a new software program. PlanOS is a platform where your unified dataset model can seamlessly flow between GE Vernova’s native modular applications. It is the foundational architecture to streamline data portability, versioning, and branching at speed. For customers with more than one of GE Vernova’s planning functionalities (Steady State Power Flow, Resource Adequacy, Production Cost, and soon-to-be-released Capacity Expansion), the standardized and enhanced user interface provides a consistent user experience that is modern and intuitive.
PlanOS enables cross functional analysis with the same data set. The PlanOS architecture aims to ensure simulations run faster without altering the model unless you intend to for accurate results.
PlanOS’ native infrastructure emphasizes accelerated planning analysis and model portability, helping to eliminate the need for manual data file conversion or the recreation of model format files for analysis.
GE Vernova’s proprietary Contingency Analysis (evaluates the impact of potential issues or unexpected events) and Transfer Analysis (evaluates the maximum amount of power that can be moved without violating system limits) capabilities will be native functionalities available for both power flow and resource adequacy analysis. This simplifies the number of software applications and APIs needed to interface with the software. Unlike other solutions, GE Vernova’s PlanOS also has built-in algorithmic processing and analytical capabilities. This enables faster analysis without relying on third-party algorithmic processing software, simplifying your IT infrastructure for planning analysis, and helps save your business time and money.
PlanOS is enabled with proprietary APIs for file conversion before or after analysis efforts, making it compatible with most industry file formats and planning software.
GE Vernova collaborates with our customers, system operators, regulators, policymakers, and developers worldwide to incorporate various regulatory and industry-leading enhancements into the software.
Additionally, we are our own customer. GE Vernova’s Consulting Services uses PlanOS for our global studies and assessments. We have developed and maintained commercially available models of over 50 countries, adapting to different grid codes, connection standards, and industry mechanisms.
Yes, the functions of PlanOS can comply with different grid codes, connection standards, industry mechanisms, and user requirements. This global approach allows GE Vernova to effectively apply lessons learned from developed regions to developing areas, addressing universal and localized grid challenges.
