This utility bill analyzer helps commercial building owners and facility managers break down electricity costs by component — demand charges, energy charges, and fixed fees — to understand where the money is going and where cuts are possible.
Enter data from your last 12 months of utility bills to get a complete picture of your energy use. Results include your Energy Use Intensity (EUI) benchmarked against similar buildings, your estimated annual carbon footprint, and your potential savings if your facility were brought up to the efficiency level of the benchmark standard for your building type.

Your numbers tell a story. A Certified Energy Manager can translate this data into a prioritized action plan — with payback periods, rebate eligibility, and an implementation roadmap.
EUI benchmarks are based on CBECS 2018 and DOE reference building data. Savings potentials are estimates based on industry averages and do not account for existing equipment condition, occupancy, or prior upgrades. Carbon calculations use EPA national average grid emissions factor (0.386 lbs CO₂/kWh) and 11.7 lbs CO₂/therm for natural gas. Results do not constitute a professional energy audit.

Utility Bill Analyzer — Frequently Asked Questions
What does this utility bill analyzer calculate? +
This utility bill analyzer breaks your commercial electricity bill into its components: consumption charges (kWh × rate), demand charges (peak kW × demand rate), fixed customer charges, and taxes/fees. Understanding the split is critical because demand charges can represent 30–70% of a large commercial bill — yet most efficiency projects target only consumption.
What's a demand charge and why does it matter? +
A demand charge is based on your highest 15-minute average power draw in a billing period, measured in kilowatts (kW). Unlike consumption, you pay for demand whether you use it or not. A single peak event — a chiller starting at the wrong time, or all equipment running simultaneously — can set your demand charge for the entire month. The utility bill analyzer helps you understand how much of your bill is demand-driven.
How do I reduce demand charges after using the utility bill analyzer? +
Load shifting, battery storage, demand-response programs, and staggered equipment startup sequences are the primary strategies. Demand charge reduction is typically analyzed as part of an ASHRAE Level 2 energy audit. A certified energy manager can identify your specific peak demand drivers and model reduction scenarios against utility tariff structures.
