Meter Set Assurance Deadline

Tucson Electric Power is committed to working closely with solar installers to ensure that their distributed generation (DG) projects advance to successful completion and meter set. Installers who wish to have a DG meter set for Level 1 or Level 2 projects before December 31must satisfy these requirements before the meter set assurance deadline of November 2, 2021:

  • Submit an approved application and all required documents in PowerClerk.
  • Submit a complete and accurate Notice of Installation Completion (NIC) form in PowerClerk.
  • Adhere to all TEP Electric Service Requirements standards (702, 703, 710 etc.), including labeling and any required facility map placards, if applicable.
  • Complete all project inspections required by TEP and the Authority Having Jurisdiction (AHJ).
  • Verify that all required clearances, including a final Distributed Generation Clearance (DGC) from the AHJ, have been submitted to TEP’s New Service Department.
  • Ensure that the customer has returned a signed Interconnection Agreement and any amendments, if applicable.

The meter set assurance date excludes Level 3 projects and any Level 2 project requiring specialized protection, communication, automation and metering (PCAM) instruments and/or equipment necessary to fulfil the Interconnection Agreement of Type 4 and Type 2 DG projects.

To avoid missing the meter set assurance deadline, please advise TEP of any potential access issues at your customer’s property. If a return meter set is required due to access issues, the project may miss the meter set assurance deadline.

New RPC Rate Effective Oct. 1, 2021

The current rate of $0.0868 per kWh, effective October 1, 2019 through September 30, 2021, will reset October 1, 2021 to $0.0781/kWh.

Projects that have been advanced to the Document Collection Status via our data management system (PowerClerk) with a timestamp prior to 11:59 p.m. September 30, 2021, will be assigned a TEP DG project number and will receive the current RCP rate of $0.0868 per kWh.

Each customer’s bill credit will initially be based on the RCP rate in effect at the time they submit an interconnection application for their system before October 1, provided that they subsequently complete the installation according to the terms and conditions in the TEP Interconnection Agreement.
