SAN DIEGO (AP) — San Diego Gas and Electric is seeking authority to bill its customers $379 million for legal settlement costs left over from 2007 wildfires that destroyed 1,300 homes and killed two people. In filings with state regulators Friday, SDG&E said customers would pay 90 percent of the costs while stockholders in the investor-owned utility would pay the remaining 10 percent — about $42 million. The fires in northern San Diego County were triggered largely by SDG&E equipment.
