Global Water Resources Reaches Settlement on Arizona Rate Cases, Adjusting Revenue and Rate Timing

Global Water Resources, a water and wastewater utility company serving Arizona, announced a settlement agreement resolving key aspects of its ongoing rate cases with the Arizona Corporation Commission (ACC). The agreement affects two of its regulated subsidiaries—Global Water – Santa Cruz Water Company and Global Water – Palo Verde Utilities Company—and outlines new revenue requirements, timing for rate changes, and adjustments to temporary customer bill credits.

This development follows rate case filings made in early 2025 and subsequent negotiations involving the company, the ACC staff, and the Residential Utility Consumer Office (RUCO). The settlement aims to streamline regulatory approval and set a clear path for future rate applications.

Key Details of the Settlement Agreement

  • Santa Cruz Water Company Revenue Increase and Rate Structure

    • The annual revenue requirement for Global Water – Santa Cruz Water Company will increase by approximately $2.3 million.
    • The agreed capital structure for ratemaking purposes is 55% common equity and 45% debt.
    • The allowed return on equity (ROE) is set at 9.6%.
    • New rates reflecting this increase are expected to take effect on November 1, 2026.

  • Palo Verde Utilities Company Rate Case Withdrawal and Future Filing

    • The pending rate case for Global Water – Palo Verde Utilities Company will be withdrawn as part of the settlement.
    • Palo Verde will refile its rate application in 2027, using a 2026 test year.
    • The future filing will not seek formula-based rates, indicating a return to traditional rate case methodology.

  • Temporary Bill Credit Adjustment for Palo Verde Customers

    • Palo Verde has agreed to seek an amendment to a prior ACC decision to increase the temporary bill credit provided to customers.
    • This bill credit addresses premature revenue collection by the company.
    • The increase in the bill credit is expected to coincide with the new Santa Cruz rates going into effect and will reduce Palo Verde’s revenue by approximately $0.4 million annually.
    • The final resolution of this bill credit will be addressed in Palo Verde’s 2027 rate case.

  • Regulatory Approval and Conditions

    • The settlement agreement is subject to approval by the Arizona Corporation Commission.
    • There is no guarantee the ACC will approve the agreement as filed; modifications are possible.

Implications for Investors

  • The approved increase in Santa Cruz’s revenue requirement and the set ROE provide clearer near-term revenue visibility for that subsidiary.
  • The deferral of Palo Verde’s rate case to 2027 delays potential revenue adjustments for that utility but includes a commitment to address customer bill credits, which will modestly reduce revenue in the interim.
  • The capital structure and ROE terms reflect regulatory expectations and will influence the company’s cost of capital and profitability metrics.
  • The settlement reduces regulatory uncertainty by resolving outstanding rate case issues and setting a timeline for future filings.

Overall, this settlement represents a significant step in managing regulatory risk and stabilizing the company’s revenue streams in Arizona, its core market.
