2016 Rate Review

How We Assessed the Cost of Providing Electricity to Our Customers

The cost of service study and review of retail rates concluded with the Austin City Council's unanimous approval of new retail rates. The Council approved a Joint Agreement between 22 parties on August 29, 2016. The agreement set new base rates for Austin Energy. Changes went into effect January 1, 2017.

The Process

The City Council's decision closed a year-long, open and transparent public review process that was designed to be more extensive and transparent than any process previously used by a municipal electric utility in Texas. The process included an Impartial Hearing Examiner who conducted an independent review of Austin Energy's rate recommendation and an Independent Consumer Advocate to represent the issues of residential and small business customers. Austin Energy staff fielded more than 1,100 questions from the public and made available thousands of pages of documents. There were about 26 intervenors in the rate review process who had the opportunity to participate in more than 30 hours of live testimony.

Thank you for your interest and participation in this process. It is this kind of public dialogue and discussion that makes community-owned power such a beneficial asset to the customers Austin Energy serves.

Key Points from the Approved Joint Agreement

Originally, Austin Energy proposed to reduce base rates by about $24 million. The joint agreement lowered base rates by $42.5 million. Base rates recover the fixed costs of the utility. A Power Supply Agreement recovers the cost of buying energy (kilowatt-hours) for resale to customers.


$5 million of the reduction went to the Residential Class.


Austin Energy's commercial classes saw $37.5 million of the reduction — about 88% of the total base rate reduction. The breakdown looked like this:

  • $1M reduction to Secondary < 10 kW (small offices, daycares, school portables, billboards)
  • $15.7M to Secondary 10-300 kW (small office buildings, retail, restaurants, small hotels)
  • $5.3M to Secondary > 300 kW (large office buildings, grocery stores, schools, hospitals)
  • $4.5M to Primary < 3,000 kW (office parks, water treatment plants, manufacturing)
  • $5.3M to Primary 3,000-20,000 kW (large manufacturing, data centers)
  • $5.5M to Primary > 20,000 kW (large industrial manufacturing)
  • No change to Transmission voltage level 1 (industrial)
  • No increase to Transmission voltage level 2 (large industrial)

Low Load Factor Floor

The Joint Agreement included a demand adjustment for customers with load factors below 20%, which effectively decreased the cents/kWh charged to those customers. This benefitted about 3,700 small- and medium-sized commercial customers.

Houses of Worship

Transition of the Houses of Worship discount continued for four more years with the following rate cap adjustments:

  • FY 2018 — 13.75 cents
  • FY 2019 — 14.25 cents
  • FY 2020 — 14.75 cents

The cap concluded at the end of FY 2020. Austin Energy continues to measure demand charges based on weekday use and prepared a study examining non-coincident peak use for commercial customers.


Seasonality was removed from base rates.

Energy Efficiency Commitment

The agreement required Austin Energy to dedicate an additional $2 million in energy efficiency benefits and free high bill audits to residential and small commercial customers without increase to the FY 2017 Energy Efficiency Services tariff.

Fayette Power Project

In agreement with Public Citizen/Sierra Club, Austin Energy agreed to meet with stakeholders in the upcoming update of the Resource Plan to discuss goals for the Fayette Power Project. The utility also committed to develop a roadmap with possible paths for ending the use of coal and starting retirement of Austin Energy's share of FPP. Any definitive action taken on FPP-related objectives remains subject to the Council’s affordability requirements.

Agreement Support

By signing the agreement, the parties agreed to not seek, fund or support an appeal of this rate review before any oversight body including the Public Utility Commission of Texas as well the Texas Legislature until the next rate review or December. 31, 2020.
