A tariff schedule book (tariff) is a pricing schedule or rate plan that regulated utilities like Golden State Water offer to its customers. Along with the pricing plan, there may be certain rules for each tariff a regulated utility offers. Each regulated water utility in California has its own tariffs, which outline approved service areas, rates and conditions of service, and defines the utility’s responsibilities and authorities, among other things. Tariffs, as well as any changes to existing rules, are subject to approval by the California Public Utilities Commission (CPUC).

As a regulated utility, Golden State Water’s rates are determined by the California Public Utilities Commission (CPUC). The rates reflect the full cost to provide water service, maintain the infrastructure and make needed system improvements.
Golden State Water is subject to state and federal requirements that guarantee the highest levels of accountability and transparency. Additionally, the CPUC provides ongoing oversight and audits of finances, operations and water quality initiatives.
General Rate Case
A General Rate Case (GRC) is a regulatory proceeding conducted by the California Public Utilities Commission (CPUC) to determine rates for regulated utilities. Every three years, the CPUC conducts an open and transparent review of Golden State Water’s rate proposal to ensure customers receive a fair rate for reliable, safe water service.
The GRC process is very thorough and generally lasts 18 months with oversight from the Office of Ratepayer Advocates, a division of the CPUC that scrutinizes the filing on behalf of customers. The utility’s customers have an opportunity to participate in the GRC process by attending Public Participation Hearings and/or testifying in a public proceeding before an Administrative Law Judge.
WRAM/MCBA Balancing Accounts
During the General Rate Case (GRC) process, the California Public Utilities Commission (CPUC) forecasts water usage in order to calculate rates that ensure revenue recovered from rates balances with expenses to operate, maintain and improve the water system. A large portion of these costs are fixed, meaning that they don’t change as usage changes. Companywide, fixed costs average 76 percent of Golden State Water’s utility expenses.
When water usage does not match the forecasted level and the revenue collected either exceeds or falls short of the CPUC-authorized amount, the Water Revenue Adjustment Mechanism (WRAM) and Modified Cost Balancing Account (MCBA) are used to achieve the financial balance. These tools ensure under-collected revenue is recovered with a temporary surcharge, and revenue that exceeds the authorized amount is returned to customers in the form of a temporary surcredit.
The CPUC model prohibits regulated utilities from keeping reserves or permanently changing rates when revenue fails to cover operating expenses during periods of reduced usage. Rather, the WRAM and MCBA ensure the revenue collected matches the amount authorized by the CPUC to continue providing reliable, quality water service—not a penny more, not a penny less.
The WRAM surcharge is offset by the MCBA, which represents savings in purchased water and energy costs that can result from reduced usage levels.
This process provides transparency and accountability, but can also present challenges during times of drought and reduced water usage.
Given the recent drought and unprecedented statewide conservation requirements, water utilities in every community must make adjustments to account for revenue shortfalls resulting from reduced usage. This is a challenge for all water providers, regulated and municipal.
