Generator Estimator

About This Tool

The Generator Estimator offers a domain-focused calculation framework to determine how long a generator can run on a given fuel volume and what fuel capacity is required for a target margin. It accepts inputs such as rated power, expected load, fuel type, engine efficiency, and fuel density to derive runtime and fuel needs. By modeling a simple, auditable fuel curve, the tool supports both basic input sets and advanced scenarios with explicit defaults when data is missing. The core value is reducing guesswork in backup power design, enabling faster, more confident capacity planning for facilities, data centers, and industrial sites. Outputs include runtime_hours, fuel_required_liters, and tank_capacity_needed_liters, with optional cost estimates when price data is supplied. Conceptually, the tool blends a load-adjusted consumption rate with a proportional runtime calculation, applying sensible defaults if a detailed fuel curve is not available. It is suitable for preliminary sizing, feasibility studies, and risk assessment during project scoping. Use cases range from emergency power continuity planning to temporary off-grid deployments during construction. The tool emphasizes transparent methods and clear result interpretation to support engineering sign-off and procurement decisions.
