City of Mesa Utilities Data Access Guide
City of Mesa Utilities (Energy Resources Department) is an Arizona municipal utility serving 18,000+ electric and 82,000+ natural gas customers, plus water and wastewater — about 95,000 combined accounts.

See the City of Mesa Utilities Rate Schedules & Tariff Guide →Interval Data & Smart Meters
Mesa is deploying AMI smart meters across water, electric, and gas through Utility Partners of America (December 2021 – October 2026; more than half complete). The portal advertises the ability to analyze and download electricity, water, and gas usage, with history aligned to the 24-month billing window starting from each meter's upgrade. Exact interval granularity (15-minute vs hourly) and download formats are not publicly documented, and there is no Green Button or ESPI export.
How to Download City of Mesa Utilities Interval Data
- 01Log into My Utility Account at https://utilities.mesaaz.gov/app/
- 02Open the Usage Analysis section
- 03Select the service type (electric, gas, or water) and date range
- 04View consumption charts and graphs
- 05Use the download feature to export usage data (format undocumented)
Interval data is essential for rate comparison and TOU analysis.

Mesa offers no utility-specific API for customer data — no developer portal, webhooks, ESPI endpoints, or aggregator partnerships. The programmatic surfaces that do exist are the Socrata-powered public Data Hub (aggregated electric, gas, and water consumption datasets with REST API and JSON/CSV export) and public ArcGIS REST services for service territory and infrastructure mapping. Customer-level access requires guest portal credentials or a negotiated enterprise agreement with Energy Resources.
Available City of Mesa Utilities API Endpoints
| Function | Endpoint | Method | Format |
|---|---|---|---|
| Aggregated electric, gas, and water consumption datasets | https://data.mesaaz.gov/ (Socrata REST API) | GET | JSON / CSV |
| Service territory, CIS mapping, and infrastructure layers | https://gis.mesaaz.gov/mesaaz/rest/services | GET | ArcGIS REST / JSON |
How to Register as a City of Mesa Utilities API Vendor

- 02For customer-level data, obtain signed authorization and guest portal credentials from the customer
- 03For bulk or recurring C&I data, contact Energy Resources (480-644-2156) to negotiate a data sharing agreement
EDI (Electronic Data Interchange)
No EDI guide, specifications, enrollment process, or VAN/direct connection information is published. Municipal utilities of Mesa's size rarely maintain EDI trading partner programs. C&I customers needing EDI-style billing exchange should contact the Energy Resources Department directly (Scott Bouchie, 480-644-2156, or contactcenter@mesaaz.gov) to discuss custom data exchange arrangements.
Rate Schedules & Tariff Analysis
Mesa publishes its utility rate schedules for electric, gas, water, and other services on the city's Utility Rates & Schedules page as PDFs. As a municipal utility, rates are adopted by the city rather than filed with the state commission; C&I customers should review the current schedules and contact Energy Resources for account-specific rate questions.

Other Data Access Programs
Public Data Hub (Open Data)
Socrata-powered open data portal with datasets including Electric Consumption and Customer Count, natural gas consumption metrics, Water Consumption by Premises, Water Treatment & Distribution Energy Usage, and City Energy Usage comparisons. Public, read-only, no authentication; REST API with JSON/CSV export. Aggregate data only — useful for trends and reporting, not C&I billing.
Smart Meters Project (AMI Rollout)
City-wide AMI deployment across water, electric, and gas by Utility Partners of America, launched December 2021 with completion scheduled for October 2026. More than half of all meters are upgraded, using wireless radio transmitters for remote reading.
CIS Modernization (SpyCIS / MyMesaWater)
Mesa is replacing its 25+ year-old Cogsdale customer information system with cloud-based SpyCIS (announced March 2026) and a new MyMesaWater portal replacing Invoice Cloud, bringing enhanced self-service, mobile access, and real-time updates during 2026.
Budget Payment Plan

City of Mesa Utilities Data Access FAQ
How do C&I customers access City of Mesa usage and billing data?▾
Register each account in the My Utility Account portal at https://utilities.mesaaz.gov/app/ using the account number and service ZIP. The portal supports multi-account management and provides up to 24 months of billing and payment history plus usage analysis and download for electric, gas, and water. Bills are available as PDF; there is no API or standardized structured export.
Does Mesa provide interval data from its smart meters?▾
Partially. Mesa's AMI rollout (Utility Partners of America, December 2021 through October 2026, more than half complete) supports 15-minute or hourly intervals, and the portal advertises usage analysis and download. However, the exact granularity and export formats are undocumented, and data only starts from each meter's smart upgrade date. There is no Green Button or ESPI export.
How can a consultant or energy manager access a client's Mesa data?▾
Use the portal's guest access feature: the customer signs an authorization letter, enables guest access in My Utility Account, and provides guest credentials to the third party, who can then view and download whatever the customer account shows. Mesa has no Share My Data program, customer-data API, or aggregator partnerships.
Does City of Mesa support EDI for commercial billing?▾
No EDI program is documented — no specifications, enrollment process, or VAN information exists publicly, which is typical for municipal utilities of Mesa's size. C&I customers needing electronic billing exchange should contact the Energy Resources Department directly (Director Scott Bouchie, 480-644-2156, or contactcenter@mesaaz.gov) to discuss custom arrangements.
What programmatic data does Mesa expose publicly?▾
Two free, no-auth APIs: the Socrata-powered Data Hub at https://data.mesaaz.gov/ with aggregated electric consumption/customer counts, gas, and water datasets (REST API, JSON/CSV export), and ArcGIS REST services at https://gis.mesaaz.gov/mesaaz/rest/services for service territory and infrastructure layers. Both are aggregate or spatial only — no customer-level usage.
Where are Mesa's utility rates published, and who sets them?▾
As a municipal utility, Mesa sets its own rates through the city budget process rather than the Arizona Corporation Commission. Current electric, gas, and water rate schedules are published as PDFs at https://www.mesaaz.gov/Government/Management-Budget/Utility-Rates; there is no retail supplier choice.
