Edison International said its fourth quarter earnings fell as lower production hurt results at the company’s power plants. A $22 million gain from sale of overseas power facilities by the state’s largest utility provider helped offset the decline.

Rosemead-based Edison on Wednesday reported fourth quarter net income of $288 million (87 cents per share). The 6 percent rise from $272 million (82 cents) for the same period a year earlier beat analyst predictions of 51 cents per share. Revenues rose 3 percent to $3.07 billion.

For the year, the utility company said net income increased 3 percent to $1.18 billion ($3.58 per share), which was its slowest growth since 2003. Sales rose 7 percent to $12.62 billion.

The company also said it plans on spending $12 billion through 2010 to expand and update its power system, electricity generators and transmission lines.

Shares in Edison were up 6 cents to $46.89 in afternoon trading on the New York Stock Exchange Wednesday.
