Interval Data & Smart Meters

Avista has deployed Itron OpenWay AMI smart meters that collect 15-minute interval data. However, customers and third parties can only view hourly aggregated usage through the myAvista portal's View Usage tool; raw 15-minute interval data is not directly customer-accessible without a custom EDI/API arrangement.

Meter Technology
Itron OpenWay AMI smart meters; meter data management head-end system.
Electric Granularity
15-minute intervals collected by AMI; exposed to customers as hourly aggregates in the portal.
Gas Granularity
Daily/billing-cycle usage via portal.

Rate Schedules & Tariff Analysis

Avista's WA electric C&I schedules use a basic-charge + tiered-energy + demand-charge structure, with progressively lower energy rates as customer size increases (Schedule 11 to 21 to 25). Large customers face substantial fixed demand charges and contract/annual minimums, so load factor and demand management materially affect total cost. All schedules are layered with cost-recovery riders and a decoupling mechanism.

Avista Utilities Rate Schedule List

ScheduleApplicability
Schedule 11 - General ServiceGeneral commercial service through one meter.
Schedule 21 - Large General ServiceLarge general service; contract required.
Schedule 25 - Extra Large General ServiceIndustrial 3,000+ kVa loads.

Avista Utilities Rate Features & TOU Details

  • Declining-block energy pricing across size tiers
  • Significant demand charges ($10/kW; $12.98/kVa for XL)
  • Primary voltage discounts for customer-owned transformation

  • Multiple riders (Schedules 58/61/63/64/66/88/91/92/93/98/99) and decoupling Schedule 75

Avista Utilities Data Access FAQ

How can a C&I customer get 15-minute interval data from Avista?

Avista's AMI meters collect 15-minute data, but the myAvista portal only displays hourly aggregates. To obtain raw 15-minute interval data, C&I customers must arrange a custom EDI, SFTP, or Avista Digital Exchange data feed by contacting Avista Business Services at (800) 936-6629.

Can an energy consultant access our Avista account data?

Yes. The account holder can authorize a consultant through the Account Manager feature in the myAvista portal, granting portal access to billing and usage data. There is no automated third-party API for this path; for programmatic access use the Avista Digital Exchange SDK.

Does Avista support Green Button?

No. Avista has not implemented Green Button Download My Data or Connect My Data (ESPI). Programmatic access is available only through the Avista Digital Exchange SDK or custom EDI/SFTP arrangements.

What programmatic options exist for developers?

The Avista Digital Exchange (ADE) provides a Python SDK (avista-digital-exchange-sdk) authenticated with Energy Collaboratives tokens. It supports data store management and IoT/meter time-range queries. Request access via Avista Business Services.

Is there a public REST API?

No public REST or SOAP API is documented. The Avista Digital Exchange Python SDK is the primary programmatic path; custom REST/SFTP access may be available to enterprise customers on request.
