1 Figure 2: Inefficient Usage Estimates by Rate Class Caused by One Percent Differential

AI summary Figure 2 illustrates estimated inefficiencies in energy usage across rate classes resulting from a 1% pricing differential. The visual representation highlights disparities in consumption patterns influenced by rate structures, a key consideration in regulatory proceedings related to utility pricing and efficiency.

4.3 Residential Time-of-Day Most of the energy usage in this class is consumed during the off-peak period, and the rate is designed to encourage this behaviour. Comparing the average annual unit revenue to the average annual marginal cost is not meaningful for specific Time-of-Day (TOD) periods, since the average marginal cost reflects the costs in all hours, while the unit revenues are designed around specific time periods. To make the test meaningful, individual TOD rates are compared to average marginal costs calculated for the hours in which the TOD rates are in effect. The TOD rate has passed the test under all three pricing periods. 4.4 Time-Varying Pricing The TVP Pilot Program offers two types of tariffs: CPP and TOU tariffs, available to a limited number of eligible customers in the Domestic Service, Small General, and General Classes.[16](#page-22-2) The rates in these tariffs are designed to encourage customers to shift energy consumption from peak to off-peak hours when the cost of electricity is lower and to reduce peak load thereby reducing upward pressure on system capacity. The TVP tariffs were approved for use to a limited number of customers on June 22, 2021, as a pilot program beginning November 1, 2021. The SRMC test for these classes was conducted for the first time in the 2022 Report. The Multi-Unit Residential Building Time-Of-Use (MURB TOU) available to General Class customers was approved effective November 1, 2024. The SRMC test for the MURB TOU class is conducted for the first time in the 2025 Report. As is the case with the TOD rate, comparing the average annual unit revenue to average marginal cost is not meaningful for specific time-varying periods, since the average annual marginal cost reflects the costs in all hours, while the unit revenues are designed around specific time periods. p. pp. 23-24

AI summary The Shore Power Tariff passed the SRMC test in 2025, with unit revenues (15.121 cents/kWh) 83% above the average marginal cost (8.259 cents/kWh) during April-November. The test compares revenues to daytime marginal costs during the service season, as seasonal cruise ship demand occurs in daytime hours, making annual comparisons inappropriate.

AI summary The document compares two approaches for determining unit revenue and marginal cost: the current approach based on long-term load forecasts and an alternate approach using daily price elasticities from a TVP pilot. The alternate approach shows significantly higher inefficiencies, particularly during on-peak and off-peak winter hours, suggesting a potential impact on demand-side management strategies.

AI summary The text presents data on demand and pricing across different categories, including General Demand, MURB, and various industrial and municipal sectors, with metrics such as percentages, costs, and usage estimates. It references the Short Run Marginal Cost (SRMC) test and inefficient usage estimates for 2025, based on an average annual marginal cost of 9.048 cents/kWh.

AI summary The text discusses the distinction between short-run and long-run economic responses to changes in electricity prices, using space conditioning and thermostat adjustments as examples of short-run responses, while long-run responses include equipment upgrades and efficiency improvements. It references studies on gasoline demand and energy efficiency in California.

Time of Use Rates Time-of-use (TOU) rates, where t e kilowatt hour ·charge depends on whether the customer's load is at 3 am or 3 pm, permit prices to be aligned more closely with the marginal cost of supplying electricity. Increased use o...

AI summary Time-of-use (TOU) rates align electricity prices with the marginal cost of supply, promoting efficiency and better cost alignment for customers. While TOU rates are used for large customers in California, residential adoption faces technological and economic barriers. Widespread implementation could increase demand elasticity and allow for technological innovations in energy management.

AI summary In a regulated retail electricity market, supply elasticities do not exist because utilities must meet all demand at set prices. However, in wholesale markets, supply elasticities are present and influenced by factors like transmission constraints and hydro conditions. Fossil-fueled generation and hydropower play significant roles in determining supply elasticity.

AI summary Restructuring the electricity market introduces new markets and financial instruments, which can increase supply elasticities by reducing investor risks. However, due to high capital costs and long lead times, generation supply may remain inelastic. Public pressures and alternative investments like transmission upgrades or energy efficiency may also influence market responses.
