About AZ Energy Hub
AZ Energy Hub is an independent publisher of Arizona energy calculators and utility guides. We help Arizona residents understand electricity bills, choose when to run appliances, and explore changes to household energy costs.
What we publish
Start with APS and SRP bill estimates, peak-hour schedules, or demand charges. Our other tools explore EV charging, pool pump costs, solar and battery scenarios, and backup power for the loads you enter. Each tool explains which plans and situations it covers.
Current structures
Seasonal tiers are modeled instead of flattened into one headline rate.
Visible sources
Core pages link to the utility or agency document behind each material claim.
No sales funnel
No affiliate links, installer leads, sponsored rankings, or paid placements.
How we create the site
AI tools are used to research, write, and develop this site, including source comparisons and calculation tests. Guides link to the official documents used; calculators show their assumptions. A source-check date records that comparison, not a review by a licensed professional. Examples are illustrative unless stated otherwise. We do not claim hands-on equipment testing or personal experience we have not documented.
How the calculations work
- Utility prices: calculations are tied to a named tariff or ratebook, not a generic utility average. The source ledger records each effective period and check date.
- Solar production: the solar tool requires a documented annual value from a current PVWatts result, installer design, or measured system data. It sends no calculator inputs to NLR and does not substitute a fallback average.
- Incentives: solar and battery worksheets insert no automatic federal, Arizona, utility, or product incentive. Users can enter an amount only after verifying their own eligibility; current IRS timing is linked for federal context.
- Battery programs: APS Storage Rewards is modeled as $110 times seasonal average delivered kW—not as a purchase rebate or guaranteed per-event payment.
- Limitations: base-rate tools state when adjustors, taxes, fees, financing, interval data, or account-specific charges are excluded.
Primary-source record
The source ledger records the owner, document type, effective period, check date, status, and affected routes for every material source used by the current publication set.
Corrections
Utility rates and programs change. If a calculator does not match a current official document or a bill you received, email contact@azenergyhub.com with the plan name, date, and source. Corrections to material rate, program, tax, safety, or calculation claims are prioritized.
Disclaimer
All results are estimates, not financial, tax, legal, engineering, or utility advice. Confirm your rate plan, tax situation, equipment eligibility, interval usage, installer scope, and contract terms with qualified professionals before acting.
