Home Energy Analysis: How AI Energy Plans Models Your Household
A home energy analysis models a household's actual electricity usage against available electricity plans, battery storage configurations, and solar options to estimate cost and identify where a household could reduce its bill. It's built from a household's own usage pattern rather than a generic, one-size-fits-all assumption.

- •A home energy analysis models a specific household's usage — it isn't a generalized average applied to everyone.
- •It draws on electricity bill or usage data, current plan rate data, and household-specific inputs like battery or solar interest.
- •Outputs typically include a plan ranking, a battery/solar fit assessment, and modeled cost estimates.
- •All estimates are modeled projections, not guarantees — actual results depend on real-world usage and market conditions.

What Is a Home Energy Analysis?
A home energy analysis is the process of comparing a household's real electricity usage pattern against the electricity plans, battery configurations, and solar options actually available to that household, in order to estimate which combination would minimize cost or meet a specific goal such as backup power or bill predictability.
Unlike a generic savings calculator that applies one average usage profile to every visitor, a home energy analysis is built around a specific household's consumption — how much electricity is used, and increasingly, when it's used throughout the day. That distinction matters because, as covered on our Time-of-Use plans and battery arbitrage pages, the value of many plans and equipment configurations depends heavily on the timing of usage, not just the total.
What Data Goes Into an Analysis
A home energy analysis draws on a household's electricity usage data — ideally from a recent bill or interval usage history — combined with current electricity plan rate data for the household's service area, and any household-specific inputs such as interest in a battery, solar, or backup power.
Usage Data
Monthly totals from a bill, or ideally interval (hourly or 15-minute) usage data, which allows time-based plan and arbitrage modeling.
Current Plan & Bill Details
The household's existing rate, contract terms, and TDU, used as the baseline for comparison.
Available Plan Data
Current electricity plans available in the household's service area, refreshed on a regular basis — see our methodology for update frequency.
Equipment Inputs (Optional)
If evaluating a battery or solar, inputs such as home size, roof characteristics, or backup priorities refine the modeling.
What the Analysis Produces
A completed home energy analysis typically produces a ranked comparison of electricity plans estimated against the household's usage, an assessment of whether battery storage or solar would likely add value given that usage pattern, and modeled cost or savings estimates with the underlying assumptions disclosed.
Plan Ranking
Electricity plans estimated against actual usage, not just advertised rate — see Compare Electricity Plans →
Battery Fit
Whether a battery, used for backup, arbitrage, or both, is likely to add value for this household.
Solar Fit
Whether solar production would likely offset a meaningful share of usage, given the home's characteristics.
Modeled Cost Estimate
Projected annual or monthly cost under the recommended configuration, with assumptions stated.
How This Differs from a Generic Calculator
A generic online savings calculator often applies one assumed usage profile — such as a flat average household — to every visitor, regardless of their actual consumption. A home energy analysis instead uses the household's own usage data, which produces a materially different, more accurate result for households whose usage doesn't match the assumed average.
“An estimate is only as good as the usage data behind it. The more accurately a household's real consumption pattern is captured, the more the resulting analysis reflects that specific home rather than a generic profile.”
On accuracy and limitations: A home energy analysis produces modeled projections based on historical usage, current plan data, and stated equipment assumptions — not guarantees of future cost. Usage patterns, weather, and market rates can all change. Full assumptions, data sources, and limitations are documented in our methodology.
