Arizona Public Service Company (APS) Data Access Guide
Arizona Public Service (APS) is the state's largest investor-owned electric utility, serving roughly 1.4 million customers across 11 Arizona counties under Arizona Corporation Commission regulation. For commercial and industrial accounts, APS provides self-service billing and daily usage data through its online portal and mobile app, with AMI smart meters deployed to about 1.1 million premises. APS has not implemented Green Button Connect or a standardized third-party data API, so C&I data sharing relies on portal downloads, Letters of Authorization, and direct data-access agreements.

APS has deployed Landis+Gyr Gridstream AMI smart meters to roughly 1.1 million customers (as of 2023), with 500,000 additional meters planned through 2030. Customers can view daily usage through the portal and mobile app. While AMI infrastructure can capture 15- and 30-minute intervals, granular sub-daily interval data is not generally exposed to customers or third parties through a self-service channel; 15/30-minute data is primarily used for demand-response and DER programs.

APS does not publish a developer portal or OAuth-based API for third-party access to customer billing/usage data. The only programmatic, device-level access is through the EnergyHub Mercury DERMS platform for enrolled distributed-energy-resource devices (smart thermostats, batteries, solar inverters, water heaters) in APS's Virtual Power Plant programs. For C&I data access, APS directs requesters to formal Letters of Authorization or custom data-access agreements via Solutions for Business.

- 02For DER device data, partner with EnergyHub for Mercury DERMS integration
- 03Obtain explicit customer authorization (LOA for business accounts) before requesting data
- 04For large accounts, negotiate a formal data-access agreement directly with APS (typically 4-12 weeks)
EDI (Electronic Data Interchange)
APS supports Electronic Data Interchange (EDI) for suppliers and business partners, oriented toward procurement and payments rather than customer energy-data exchange. EDI files are delivered over a Value Added Network (VAN) using ANSI ASC X12 (with UN/EDIFACT and XML also supported). Suppliers connect directly or through managed providers such as TrueCommerce.

Rate Schedules & Tariff Analysis
APS C&I customers are tier-assigned by average summer maximum demand and then choose non-TOU or TOU. Demand charges dominate the bill for larger accounts — the E-32 L demand charge of $29.422/kW (first 100 kW) means peak management is the single biggest lever for cost control. TOU plans (on-peak 3:00-8:00 pm weekdays) trade higher peak energy rates for lower off-peak rates and can materially reduce costs for facilities that can shift load. Summer (May-October) rates are higher than winter across all plans. All figures verified against APS tariff sheets effective March 8, 2024 (ACC Decision No. 79293).
