Arizona / APS
Independent APS Rate and Energy-Cost Review
GridLogic provides energy-cost analysis for homeowners and businesses evaluating rate options, solar, battery storage, demand response, facility expansion, flexible-load strategies, and operational changes.
| Review area | What GridLogic reviews |
|---|---|
| Rate and bill analysis | Determine most economical rate by comparing current rate with available alternative rate plans. |
| Usage and demand | Evaluate residential or commercial usage timing, demand charges, and load-shifting opportunities that may lead to bill savings. |
| Project economics | Estimate bill savings/costs based on customer-provided information, public tariffs, billing data, usage data, and reasonable analytical assumptions. Results may vary with actual savings/costs. |
| Decision scenario | Solar, battery storage, demand response, EV charging, facility expansion, and operational changes |
| Realized project savings | If system is already installed, a forensic analysis can be done to calculate bill savings using 12 months of historical interval usage, production, and export data. |
What the review answers
Understand the bill before making the decision
The review identifies what is driving current costs and how a proposed rate, project, or operating change could affect them.
Is my current rate appropriate?
How would solar change my bill?
How much solar would I use versus export?
Would storage, demand response, or load shifting add value?
Which assumptions materially affect the result?
Information commonly used for the review
- 12 months of APS bills or billing data
- Hourly or interval usage data, if available
- Current APS rate schedule
- Solar, storage, or demand response proposal, if applicable
- Proposed system size and production estimate
- EV charging, facility expansion, or operating changes being considered
Additional information may be requested depending on the scope of the review.
