Mason PUD 3 publishes no developer portal, API documentation, or formal aggregator program. All customer data flows through NISC iVUE/SmartHub. Community projects (electric-usage-downloader, ha-smarthub on GitHub) have reverse-engineered the SmartHub JSON API to pull 15-minute interval data, but this is unsupported and at the user's own risk. Programmatic access inquiries can be directed to NISC.

Mason County PUD No. 3 Data Access FAQ
Does Mason PUD 3 support Green Button exports for C&I accounts?▾
Yes — Green Button Download My Data is live in SmartHub. From the My Usage tab, download up to 14 months of usage as zipped ESPI XML (NAESB REQ.21 compliant) and import it into energy management or benchmarking tools. Connect My Data (automated token-based sharing) is not enabled.
What interval granularity does Mason PUD 3 provide?▾
Daily kWh is the documented granularity in SmartHub. The AMI meters can collect finer intervals, and Green Button exports contain data at the meter's available resolution, but 15/30-minute availability is not publicly confirmed — call (360) 426-8255 to verify for a specific account.
How do consultants or aggregators get authorized access to PUD 3 customer data?▾
There is no aggregator program or authorization portal. Get a signed customer data release, then contact PUD 3 at (360) 426-8255 (M-Th, 7 AM-5:30 PM PT) specifying data type, period, and format. Extracts arrive by email or paper in roughly 5-10 business days; the simplest path is having the customer share Green Button XML files directly.
Does Mason PUD 3 offer EDI or a public API?▾
No public EDI trading partner program or API exists. EDI may be negotiable case-by-case through the billing department. Community projects have reverse-engineered the NISC SmartHub JSON API for 15-minute data pulls, but that approach is unsupported and at the user's own risk — production integrations should go through NISC or sanctioned file-based exports.
How far back can usage history be pulled from Mason PUD 3?▾
Green Button DMD allows up to 14 months per request — shorter than the 3+ years some large utilities offer. SmartHub shows daily data for current and prior billing periods; for longer billing history, submit a customer-authorized manual request to the utility.
