Generator Estimator Chart

About This Tool

The Generator Estimator Chart provides a structured, math-based approach to sizing generators for defined conditions. It accepts peak load, generator rating, runtime, and efficiency as core inputs, with optional downtime and fuel-efficiency data for advanced scenarios. The result is a chart-backed estimation that guides capacity decisions and budget planning. Conceptually, the tool translates operational load into a required capacity and then translates that capacity into fuel and energy estimates, enabling quick evaluation of multiple scenarios. The core value lies in consistent calculations, repeatable results, and a visual summary that supports reporting to stakeholders. Use cases include facility upgrades, emergency backup sizing, and maintenance planning where rapid, defensible estimates are needed without bespoke engineering studies. Unique differentiators include scenario comparison, explicit handling of downtime and efficiency, and export-ready outputs for integration into reports. Core features include multi-input calculations, a bar-chart visualization of load versus capacity, a trend line across scenarios, and data export. The tool is designed for engineers, plant managers, and procurement teams seeking fast, transparent estimations with auditable inputs and outputs.
