functional areas of generation, transmission, distribution, and retail. The marginal generation costs used by the Company in the SRMC test reflect; however, only the marginal fuel and generation, operation and maintenance cost. They do not...

AI summary The document discusses the marginal generation costs used by the Company in the SRMC test, highlighting that these costs do not include fixed costs from generation, transmission, distribution, or retail. It notes that marginal costs have fluctuated due to generation mix changes, commodity prices, and load increases, with a significant increase in 2025.

Current Supply Elasticity Estimates Supply elasticities, per se, do not exist in a regulated retail electricity market. Prices are set beforehand in a regulatory proceeding, and utilities must supply all retail power demanded at the price...

AI summary In regulated retail electricity markets, supply elasticities do not exist as prices are predetermined, requiring utilities to meet demand at set rates. However, in Western wholesale markets, supply elasticity exists due to competitive generation and transmission constraints. Hydropower availability and fossil fuel costs further influence elasticity, making it weather-dependent and volatile.

calendar year. This is because the unit revenues are reflective of total costs of service of the four functional areas of generation, transmission, distribution, and retail. The marginal generation costs used by the Company in the SRMC tes...

AI summary This section explains the relationship between unit revenues and marginal generation costs, noting that marginal costs typically exceed average system fuel costs but not overall unit revenues. It also highlights changes in marginal costs from 2022 to 2025, attributed to shifts in generation mix, commodity pricing, and load increases.

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.

ormance-based rate. Even if the market prices fall below operation and maintenance costs, owners of "must-run" generation may have no incentive to reduce output or to cease operating the power plants. As a result of restructuring, the scop...

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.
