SCE updated its 2025 revenue requirement request to $10.5 billion, including a $220 million increase associated with the cost of capital adjustment. However, a subsequent CPUC decision in October 2024 modified the cost of capital adjustment mechanism, reducing the revenue requirement by approximately $117 million.

The CAISO released its 2022 – 2023 Transmission Plan based on the CPUC's projections that more than 40 gigawatts of new resources need to be added in California by 2032. As the incumbent transmission owner for a portion of these transmission projects, SCE expects to construct projects requiring capital investment of at least $2.0 billion, most of which will be incurred beyond 2028.

SCE, in association with Lotus Infrastructure Global Operations, LLC, was selected as the approved project sponsor for a 30-mile overhead transmission line project connecting San Diego and Orange Counties. The project is expected to be in-service in 2032.

In July 2024, the CPUC issued a decision approving SCE's request in the 2025 GRC to extend the wildfire customer-funded self-insurance through the 2025 GRC period.

In May 2024, the CPUC issued a decision approving the recovery of SCE's capital request of $312 million and operation and maintenance expenses of $200 million, resulting in a revenue requirement of $191 million plus ongoing capital-related revenue requirement.

In April 2024, SCE filed its WMCE Filing, seeking to recover incremental operating and maintenance expenses of $320 million and incremental capital expenditures of $702 million. In July 2024, the CPUC adopted a schedule with a proposed decision expected in the third quarter of 2025.

Edison International and SCE may incur a material loss in excess of amounts accrued in connection with the remaining alleged and potential claims related to the 2017/2018 Wildfire/Mudslide Events.

SCE's credit ratings may be affected if regulators fail to successfully implement AB 1054 in a consistent and credit supportive manner, or the Wildfire Insurance Fund is depleted by claims from catastrophic wildfires. Credit rating downgrades increase the cost and may impact the availability of borrowings.

SCE is unable to conclude, at this time, that uninsured CPUC-jurisdictional wildfire-related costs related to the 2017/2018 Wildfire/Mudslide Events are probable of recovery through electric rates.

The document mentions risks associated with cost allocation resulting in higher rates for utility bundled service customers because of possible customer bypass or departure for other electricity providers such as CCAs and Electric Service Providers.

The document mentions governmental, statutory, regulatory, or administrative changes or initiatives affecting the electricity industry, including the market structure rules applicable to each market adopted by the NERC, CAISO, Western Electricity Coordinating Council, and similar regulatory bodies in adjoining regions.

The document mentions the ability of Edison International and SCE to effectively attract, manage, develop and retain a skilled workforce, including its contract workers.

Severance costs of $47 million recorded in 2024 due to current and probable reductions in workforce.

Higher operation and maintenance expense of $133 million is primarily due to an increase in wildfire mitigation expense of $99 million due to higher amounts authorized in Track 4, and the recognition of previously deferred costs.

The document mentions the ability of SCE to recover its costs through regulated rates, timely or at all, including uninsured wildfire-related and debris flow-related costs and costs incurred to mitigate the risk of utility equipment causing future wildfires.

SCE contracted with Ameresco, Inc. for the construction of utility owned energy storage projects at three sites in SCE's service territory that have an aggregate capacity of 537.5 MW.

Higher depreciation and amortization expense of $164 million primarily due to increased plant balances and the recognition of $48 million of previously deferred wildfire mitigation and emergency restoration related depreciation expense in 2024

Edison International Parent and Other holds strategic investments in companies focused on innovative clean energy related technologies and services, included as "Other investments" on Edison International's consolidated balance sheets.

SCE forecasts total capital expenditures ranging from $32.2 billion to $37.5 billion for 2024 – 2028, and weighted average annual rate base from $43.0 billion to $60.6 billion for 2024 – 2028.

In the first nine months of 2024, SCE issued a total of $4.3 billion of first and refunding mortgage bonds. The proceeds were used to fund and refinance debt for the payment of wildfire claims and related expenses, repay commercial paper borrowings, and for general corporate purposes.

On July 25, 2024, Edison International announced a stock repurchase program effective July 29, 2024 for repurchase of up to $200 million of its common stock until December 31, 2025

In the TKM Settlement Agreement, SCE also agreed to $50 million of shareholder-funded wildfire- and public safety-related system enhancements.

An increase in wildfire mitigation expense of $99 million due to higher amounts authorized in Track 4, and the recognition of previously deferred costs (offset in revenue above).

Under the IRA, SCE expects to generate investment tax credits related to its utility owned storage projects, which will accrue to the benefit of its customers.

As a result of the CPUC-authorized decoupling mechanism, SCE revenues are not affected by changes in volume of retail electricity sales.

The document mentions the potential for penalties or disallowances for non-compliance with applicable laws and regulations, including fines, penalties and disallowances related to wildfires where SCE's equipment is alleged to be associated with ignition.

The document mentions extreme weather-related incidents (including events caused, or exacerbated, by climate change, such as wildfires, debris flows, flooding, droughts, high wind events and extreme heat events) and other natural disasters.
