PG&E Corp.'s (PCG) third-quarter profit rose 4.6%, beating analysts' estimates on additional revenue from new infrastructure investments.

PG&E said its Pacific Gas & Electric Co. utility has spent $3 billion on infrastructure so far this year, boosting the amount of assets on which it's permitted to earn returns. The utility's profits are more insulated from slumping power demand because California regulation decouples returns from power sales.

Pacific Gas & Electric has about 15 million customers in central and northern California and has been working to stem unpaid bills during the economic downturn in the state, with home-foreclosure rates among the nation's highest. The company has also been trimming costs, with utility president Christopher Johns saying on a conference call that the company's workforce has been cut by a little over 2%.

PG&E reported profit of $321 million, or 83 cents a share, up from $307 million, or 83 cents, a year earlier. On a non-GAAP basis, the company earned 93 cents a share compared with 83 cents. Revenue fell 12% to $3.23 billion.

Analysts polled by Thomson Reuters had most recently forecast earnings of 91 cents a share on $3.48 billion in sales.

Operating margin rose to 18.8% from 17.4%, while the utility's electricity sales declined 8.7%, and its natural gas revenue plunged 24%.

The company stuck by its financial guidance for the year, saying it still expects earnings per share of $3.15-$3.25. Analysts expect, on average, 2009 earnings of $3.16 a share. PG&E reaffirmed its guidance for 2010 and 2011 as well, saying it expects EPS of $3.35-$3.50 and $3.65-$3.85, respectively.

The company said Monday that it agreed to buy solar energy from two California projects, one from FPL Group Inc.'s (FPL) NextEra and the other from Spain's Abengoa SA (ABG.MC), as the company looks for ways to boost renewable-energy development to meet government mandates and prepare for federal constraints on greenhouse-gas emissions.

Also on Monday, California Gov. Arnold Schwarzenegger said PG&E had agreed to increase the percentage of its customers that can sell power back to the utility from rooftop solar systems to 3.5% from 2.5%. Growing customer purchases of rooftop-solar systems threatened to run up against the 2.5% cap, which would have stymied demand and solar development in the state.

Shares of PG&E were recently down 22 cents at $41.33 apiece on the New York Stock Exchange.
