2017-18 Water Rate Case

According to a September 2015 decision from the Arizona Corporation Commission(AzCC), EPCOR was required to file a water rate case. The company filed the case August 18, 2017, giving the AzCC the information it needs to make a decision on the policy of water consolidation, based on fresh financial data from 2016. The two options are:

  • Keep the 11 water districts the way they are today (status quo/standalone)
  • Or, bring them all together as one district (consolidation)

View the docket to read the Administrative Law Judge's Recommended Opinion and Order, which recommended standalone rates. On Jan. 25, 2019, the Commission ended the case with no resolution after a 2-2 deadlocked vote. Therefore, EPCOR was ordered to file an application for interim rates, which could take effect by the end of March 2019, or be backdated to as early as February 1. Those interim rates, if passed, would remain in effect until such a time as EPCOR files an entirely new rate case. That process could take 12-24 months to resolve, based on the timeline of the 2017-2018 case.

2019 Interim Rate Case
On February 20-21, 2019, the Administrative Law Judge heard the interim rate case. She will issue a recommendation no later than March 14. The Commission is scheduled to hear and vote on the case on March 28, 2019.
