8-K: Golden State Water Receives Proposed Rate Decision, Approving $573 Million Infrastructure Investment

Golden State Water Company received a proposed decision from the California Public Utilities Commission approving a settlement agreement that includes significant infrastructure investments and new rate structures.

Summary

• Golden State Water Company (GSWC) has received a proposed decision from the California Public Utilities Commission (CPUC) regarding its general rate case for 2025-2027.
• The proposed decision approves a settlement agreement between GSWC and the Public Advocates Office, authorizing approximately $573.1 million in capital infrastructure investments over three years.
• This includes $17.7 million in advice letter capital investments and $58.2 million already under construction, both to be filed for revenue recovery during the second and third year attrition increases.
• The settlement allows for additional revenue increases in 2026 and 2027, subject to an earnings test and changes in inflation.
• The decision adopts GSWC's sales forecast and a supply mix that splits the difference between GSWC and Cal Advocates' forecasts.
• The CPUC rejected GSWC's request for a full sales and revenue decoupling mechanism and a full cost balancing account for water supply, instead ordering a transition to a modified rate adjustment mechanism (M-WRAM).
• GSWC's request to modify the PFAS memorandum account was also rejected, requiring a separate application for PFAS-related capital project recovery.
• The proposed decision adopts GSWC's M-WRAM rate design, allowing an increase in service charges to 45-48% of revenue requirement, representing about 65% of GSWC's fixed costs.
• GSWC will file comments on the proposed decision by December 5, 2024, and the CPUC is scheduled to vote on it on December 19, 2024.
• New rates for 2025 will be effective January 1, 2025, if the final decision is issued by the CPUC by the end of the fourth quarter of 2024.

Sentiment

Score: 7

Explanation: The document is generally positive due to the approval of the settlement agreement and significant infrastructure investments. However, the rejection of some key mechanisms and the need for a separate PFAS application temper the overall sentiment.

Positives

• The proposed decision approves the settlement agreement in its entirety, allowing GSWC to proceed with significant infrastructure investments.
• The settlement agreement allows for recovery of $17.7 million in advice letter capital investments and $58.2 million already under construction.
• The decision adopts GSWC's sales forecast, which is a positive outcome for the company.
• The M-WRAM rate design proposal was adopted, allowing for increased revenue through service charges.
• The proposed decision provides clarity on the rate structure for the next three years.

Negatives

• The CPUC rejected GSWC's request for a full sales and revenue decoupling mechanism and a full cost balancing account for water supply.
• GSWC's sales reconciliation and supply mix adjustment mechanisms were rejected.
• The request to modify the PFAS memorandum account was rejected, requiring a separate application for recovery of PFAS-related capital projects.
• Management expressed disappointment that the full sales and revenue decoupling mechanism and full cost balancing account for water supply were not adopted.

Risks

• The final decision by the CPUC is still pending and could differ from the proposed decision.
• The actual revenue increases for 2026 and 2027 are subject to an earnings test and changes in inflation, which introduces uncertainty.
• The transition to a modified rate adjustment mechanism (M-WRAM) may have unforeseen impacts on GSWC's revenue and operations.
• The need to file a separate application for PFAS-related capital project recovery could delay the implementation of necessary infrastructure upgrades.
• The rejection of the full sales and revenue decoupling mechanism could impact the company's ability to promote water conservation and keep rates affordable for low-income customers.

Future Outlook

The new water rates for 2025 will be effective January 1, 2025, pending a final decision from the CPUC by the end of the fourth quarter of 2024. Additional revenue increases are possible in 2026 and 2027, subject to an earnings test and changes in inflation.

Management Comments

• Robert J. Sprowls, President and CEO of American States Water Company, stated they are pleased to have received a proposed decision approving the settlement agreement.
• Management expressed disappointment that the proposed decision did not adopt the full sales and revenue decoupling mechanism and full cost balancing account for water supply.

Industry Context

This announcement is significant for the regulated water utility industry in California, as it sets a precedent for rate cases and infrastructure investments. The decision to move to a modified rate adjustment mechanism (M-WRAM) reflects a trend towards balancing utility revenue stability with water conservation goals. The rejection of the full decoupling mechanism may be seen as a setback for utilities seeking to fully decouple revenue from water sales.

Comparison to Industry Standards

• The approved $573.1 million capital investment is substantial and aligns with the need for infrastructure upgrades in California's aging water systems, similar to other large water utilities in the state such as California Water Service Group (CWT).
• The transition to a Monterey-style WRAM (M-WRAM) is a common approach in California, used by other utilities like San Jose Water Company (SJW), to manage revenue fluctuations due to variations in water consumption.
• The rejection of the full sales and revenue decoupling mechanism is a notable deviation from some industry trends, where decoupling is seen as a way to promote conservation. This decision may be compared to other rate cases where full decoupling was either approved or rejected, such as those involving Southern California Edison (SCE) in the energy sector.
• The requirement to file a separate application for PFAS-related capital projects is consistent with the regulatory approach to emerging contaminants, where specific cost recovery mechanisms are often required, similar to how other utilities have addressed similar issues.

Stakeholder Impact

• Shareholders will benefit from the approved infrastructure investments and potential revenue increases.
• Customers will see improved water service reliability due to the infrastructure upgrades.
• Customers may experience rate increases due to the new rate structure.
• Employees will be involved in the implementation of the infrastructure projects.

Next Steps

• GSWC will file comments on the proposed decision by December 5, 2024.
• The CPUC is scheduled to vote on the proposed decision on December 19, 2024.
• GSWC will need to file a separate application for recovery of PFAS-related capital projects.
• GSWC will implement the new rates for 2025 effective January 1, 2025, if the final decision is issued by the CPUC by the end of the fourth quarter of 2024.
