Power Suite A Comprehensive Digital Ecosystem for Power Generation Professionals

Introduction

The design and specification of power generation systems is a complex, multi-faceted engineering challenge. It requires precise calculations for equipment sizing, careful selection of components, and access to a vast library of technical data. For specifying engineers, contractors, and consultants, having the right tools at their fingertips can be the difference between a successful project and one plagued by inefficiency and errors.

Cummins recognized this need and has developed Power Suite™, a free, industry-leading online portal for power system product sizing, specification generation, and access to a comprehensive technical library. This article provides an overview of the Power Suite™ platform, detailing its key tools and resources, and how they streamline the process of designing and specifying reliable power solutions.

The Evolution of Power Suite™

Power Suite™ has a long history of serving the power generation industry, originally being released as a compact disc (CD). Over time, it has evolved into a fully digital platform that leverages the latest technology. In June 2025, Cummins announced significant updates to the platform, designed to enhance user experience and modernize its legacy applications, with a focus on making it an industry-leading hub for sizing tools and other power generation-specific applications.

A key driver for this evolution was the need for a more efficient and intuitive user experience. The updates to Power Suite™ are a direct response to this, providing users with unlimited projects, a faster and more reliable system, and a modernized user interface. The platform also reflects the growing importance of data-driven design in power generation, enabling users to make confident decisions quickly.

Key Tools and Resources within Power Suite™

Power Suite™ is a comprehensive platform that integrates several powerful tools and resources into a single, unified interface. This integration simplifies the workflow for power generation professionals, allowing them to move seamlessly between tasks.

Product Finder

The Product Finder is an intuitive tool that allows users to browse Cummins' full range of power generation products, including generator sets, automatic transfer switches (ATS), and paralleling systems. It includes a comparison function, shortcuts to the library, and advanced filter options, making it easier than ever to find the right product.

GenSize™ 2.0

The most significant feature within Power Suite™ is GenSize™ 2.0, an advanced sizing tool that provides product recommendations according to customers' loads and project parameters. According to Cummins, the GenSize™ 2.0 upgrade offers a number of key improvements over its predecessor. The modernized user interface includes features like predictive search, drag-and-drop functionality, and smart summaries. Perhaps most importantly, the system performance is faster and more reliable, with optimized accuracy following a thorough review of algorithms and product data tables.

A major improvement is the removal of the previous 99-project cap, enabling users to create and manage unlimited projects. This eliminates a significant constraint for professionals working on numerous projects simultaneously and positions GenSize™ 2.0 as a truly scalable tool. Direct product comparison features also make product selection a much more reassuring experience.

GenCalc™

For comprehensive project planning, GenCalc™ is a suite of tools developed by expert engineers to calculate a range of project parameters, including ventilation, short circuit, exhaust back pressure, remote cooling, and fuel pipe sizing. It is now available globally, supporting both metric and US customary units.

GenSpec™

The GenSpec™ tool is a specification development tool that provides sample specifications for generator sets, ATS, and paralleling systems, tailored for both North American and European applications. This helps streamline the specification writing process and ensures that critical requirements are not overlooked.

Cummins Content Library

Power Suite™ features an upgraded technical catalog, known as the Cummins Content Library. This library consists of a wealth of resources, including specification sheets, data sheets, and drawings for generator sets, ATS, paralleling, networking, and remote monitoring systems. The region-specific product library makes it easier to locate the required product documentation.

Continuing Education

Beyond these powerful design tools, Power Suite™ also serves as a hub for professional development. The platform offers programs, including educational seminars and webinars, to help professionals grow their technical knowledge and fulfill continuing professional development requirements. For instance, a recent "PowerHour" session was designed to teach specifying engineers about the redesigned GenSize™ 2.0 tool and help them earn a Professional Development Hour (PDH) credit.

Free Access and the Path Forward

Power Suite™ is a free portal for all users to sign up and use. This accessibility lowers barriers to efficient power system design, making world-class tools available to a broad range of professionals.

This update marks the start of Power Suite™'s innovation journey, with upcoming features like the BESS (Battery Energy Storage Systems) sizing tool and the modernized Site-Specific Rating tool anticipated in the future. This indicates a commitment to continuous improvement and evolution, ensuring that the platform remains a cutting-edge resource for the power generation industry.

Conclusion

Power Suite™ by Cummins represents a significant step forward in providing a comprehensive, integrated, and user-friendly digital ecosystem for the power generation industry. By combining advanced tools like GenSize™ 2.0 and GenCalc™ with a vast technical library and educational resources, it addresses the core needs of specifying engineers and contractors. As the platform continues to evolve and integrate new features, it is poised to remain a leading hub for power system design and specification. For professionals in this field, it is a free and invaluable asset for delivering reliable power solutions with confidence.
