Rates

Post

As a regulated utility, every three years Golden State Water’s rates are determined by the California Public Utilities Commission (CPUC) through a General Rate Case (GRC) to ensure customers receive a fair rate for reliable, quality water service. New rates allow for investments to avoid the costly and sometimes dangerous effects of deferring maintenance or delaying the replacement of aging infrastructure.

2023 GRC (2025 Rates)

As required by the CPUC every three years, in August of 2023, Golden State Water Company filed its 2023 General Rate Case (GRC) with the California Public Utilities Commission. This rate plan proposes local infrastructure investments and water rates for the years 2025, 2026 and 2027. Any adjustments to current rates will not go into effect until January 2025, at the earliest.
