APS/TEP/UNSE Utility REST 2011 Compliance Reports

(download full brief)

The essentials

  • In 2006, the Arizona Corporation Commission adopted the Renewable Energy Standard and Tariff (“REST”) rule requiring regulated electric utilities in the state to obtain some of their energy from renewable sources, such as wind, solar, geothermal and biomass.
  • Every year, a prescribed percentage of each affected utility’s electricity sales must come from renewable sources. The percentage required gradually increases until reaching 15% in 2025.
  • To ensure that each utility company is on track towards meeting its REST requirement, it must file two separate documents annually: 1) a Compliance Report and 2) an Implementation Plan.
  • In the Compliance Report, each company tracks its progress in renewable energy sales. The progress is tracked with Renewable Energy Credits.
    • In the Implementation Plan, each company describes its plan to meet the next year’s requirement.
    • This brief covers the Compliance Reports. Please also see our corresponding brief on this year’s Implementation Plans:“APS/TEP/UNS Utility REST Implementation Plans.”
