May 8, 2008 - Edison International Reports First Quarter 2008 Earnings

First quarter 2008 GAAP earnings were $0.91 per share compared to $1.01 per share in the first quarter of 2007.
Core earnings increased 2% to $0.92 per share in the first quarter from $0.90 per share in the year-ago quarter, reflecting an increase of $0.01 per share at both Southern California Edison (SCE) and Edison Mission Group (EMG). The increase was largely due to lower net interest expense at SCE and higher gross margin at EMG�s Midwest Generation. Core earnings exclude non-core items and discontinued operations.
The current outlook for Edison International 2008 core earnings is around the high end of its guidance range of $3.61 - $4.01 per share.

ROSEMEAD, Calif., May 8, 2008 � Edison International (NYSE: EIX) today reported first quarter 2008 earnings of $0.91 per share. Excluding non-core items, first quarter 2008 core earnings were $0.92 per share, up two percent compared with $0.90 per share in the year-ago first quarter.

"First quarter results were solid. Our improved outlook for the full year reflects positive margin trends in our unregulated power generation business," said John E. Bryson, chairman and chief executive officer of Edison International.

Earnings from Continuing Operations

SCE�s first-quarter 2008 earnings from continuing operations were $0.46 per share, compared to earnings of $0.55 per share in the same quarter last year; this decrease was primarily due to a non-core tax benefit of $0.10 per share last year from the favorable resolution of the income tax treatment of certain environmental remediation costs. Excluding the tax item, SCE�s core earnings in the first quarter increased $0.01 per share, compared to the same quarter last year. This increase was primarily due to lower net interest expense.

EMG�s first-quarter 2008 earnings from continuing operations and core earnings were $0.49 per share, compared to $0.48 per share in the same quarter last year. The increase was primarily due to higher gross margin and the buy-out of a coal contract at Midwest Generation together with higher energy trading results. This was partially offset by lower earnings from Edison Capital and other generation projects together with higher costs associated with EMG�s growth programs.

Discontinued Operations

Edison International�s loss from discontinued operations was $(0.01) per share in the first quarter of 2008 versus earnings from discontinued operations of $0.01 per share in the first quarter of 2007; both related to the 2004 sale of its international businesses.

Use of Non-GAAP Financial Measures

Edison International�s earnings are prepared in accordance with generally accepted accounting principles used in the United States and represent the company�s earnings as reported to the Securities and Exchange Commission. Our management uses core earnings and EPS by principal operating subsidiary internally for financial planning and for analysis of performance. We also use core earnings and EPS by principal operating subsidiary as primary performance measurements when communicating with analysts and investors regarding our earnings results and outlook, as it allows us to more accurately compare the company�s ongoing performance across periods. Core earnings exclude discontinued operations and other non-core items and are reconciled to GAAP earnings per share.

EPS by principal operating subsidiary is based on the principal operating subsidiary net income and Edison International's weighted average outstanding common shares. The impact of participating securities (vested stock options that earn dividend equivalents that may participate in undistributed earnings with common stock) for each principal operating subsidiary is not material to each principal operating subsidiary�s EPS and is therefore reflected in the results of the Edison International holding company, which we refer to as EIX parent company. EPS and core EPS by principal operating subsidiary are reconciled to GAAP earnings per share.

April 16, 2008 - Keeping Your Cool: Options Suggested to Save Energy and Money This Summer

Southern California Edison Offers Variety of Alternatives for Customers

ROSEMEAD, Calif., April 16, 2008 � With summer approaching, Southern California Edison (SCE) recommends practical ways for customers to save energy, money and the environment through a variety of energy-efficiency programs and services.

�We are encouraging our customers to take advantage of these programs and start saving money and energy right away,� said Lynda Ziegler, SCE�s senior vice president of customer service. �We have more incentives than ever, including our air conditioner tune-up program and our Summer Discount Plan.�

Tuning up an air conditioner can save up to 30 percent on cooling costs and extend a unit�s life as much as eight years. SCE�s A/C Tune-Up Program offers up to $150 back to customers for each unit serviced, depending on the level of tune-up they purchase from a licensed contractor. The tune-up must occur between April 1 and June 30 for customers to be eligible for a rebate. A tune-up includes condenser and evaporator coil cleaning, duct testing and sealing and refrigerant charge adjustments. Customers can expect to pay between $75 and $150 for a basic tune-up; an advanced tune-up costs $400 to $600.

The company�s Summer Discount Plan allows SCE to remotely turn off willing customers� central air conditioner compressors during a summer power emergency. In exchange, the customers get a credit of up to $200; customers can choose one of two options, depending on how many times they allow SCE to cycle off their air conditioners. Participating customers lower their energy costs and help to ensure a reliable electricity supply.

Over the past five years, SCE�s energy-efficiency programs have achieved the largest energy savings of any utility in the nation. The programs have reduced greenhouse gas emissions by more than 2 million tons � the equivalent of removing 250,000 cars from the road.

SCE customers have reduced annual energy usage by more than 1 billion kilowatt-hours, enough power to supply 140,000 average homes for a year. During the next two years, SCE will help customers save an additional 2 billion kilowatt-hours, reducing greenhouse gas emissions by approximately 1 million tons.

Other SCE energy-efficiency programs include:

Refrigerator and freezer recycling: SCE will pay customers $50 to discard their old, inefficient refrigerators, which can cost up to $290 per year to operate. The utility will pick up old models and recycle them in an environmentally responsible manner. Customers also are eligible for $50 rebates for buying new, ENERGY STAR-labeled refrigerators.
Energy-efficiency rebates: SCE provides rebates for efficient, ENERGY STAR-labeled fans, coolers and air conditioners. Customers can earn the following rebates:
- Up to $50 for room or wall air conditioners.
- Up to $100 for a whole-house fan.
- Up to $600 for evaporative cooling systems.
- Incentives of 10 to 20 cents per square foot for using reflective roof materials when replacing an old roof. This can reduce roof temperatures by 60 percent.
- Thirty dollars to $200 when replacing an old pool pump with a new, efficient one; variable-speed pumps are especially effective in reducing costs.

To learn about these and other programs, visit www.sce.com/save or call (800) 369-3652.
