Backup Power Calculators
Professional-grade compliance calculators for facilities that depend on backup power. Built by the team behind FuelCare — servicing generator fuel systems since 1997.
Compliance & Fuel Calculators
CMS Required
96-Hour Fuel Rule Calculator
Calculate diesel fuel storage required to satisfy CMS 42 CFR 482.15 and NFPA 110 including the mandatory 133% safety buffer.
All Facilities
Fuel Consumption Calculator
Real-world fuel burn rates at varying loads with non-linear consumption curves, altitude derating, and temperature adjustments.
Fuel Planning
Generator Runtime Calculator
How long will your fuel last? Model runtime at multiple load levels and plan refueling schedules for extended outages.
EPA Required
SPCC Threshold Calculator
Does your aggregate oil storage trigger EPA 40 CFR Part 112 reporting? Calculate your total across all tanks.
NEW
Fuel Health Predictor
Is your stored diesel still safe? Science-based degradation model predicts oxidation, water, and microbial risk with actionable recommendations.
Sizing & Planning Calculators
Design Phase
Generator Sizing Calculator
Right-size your generator to actual load with motor starting surge, redundancy planning, and NEC/NFPA compliance.
Reliability
N+1 Redundancy Planner
Model N+1, N+2, and 2N redundancy configurations with failure probability and availability analysis.
NEC Compliance
Transfer Switch Sizing
Size automatic transfer switches for NEC Article 700/701/702 emergency and standby power systems.
EPA Compliance
Emissions Calculator
Estimate NOx, PM, CO, and VOC emissions from diesel generators for air permit compliance.
Operations & Maintenance
Operations
Maintenance Scheduler
Build a 12-month compliance maintenance calendar with tasks, deadlines, and regulatory checkpoints.
NFPA 110
Load Bank Test Planner
Plan load bank testing for NFPA 110 compliance. Build a 36-month test schedule and assess wet stacking risk.
Financial
Total Cost of Ownership
Model the full lifecycle cost of generator ownership: capital, fuel, maintenance, testing, and compliance.
Telecom & 5G
5G Ready
Telecom Generator Sizing
Size generators for telecom sites including 5G radio power, cooling loads, and battery charging.
Network Planning
5G Power Demand Calculator
Estimate power requirements for 5G deployments: massive MIMO, small cells, and edge computing.
