Your electricity bill is going up next year. The California Public Utilities Commission on Thursday approved San Diego Gas & Electric’s request to increase customers’ electricity bill by 2.6% next year, which is equivalent to about $4.38. Natural gas customers will see a 1.8% increase, or $1.02. Those enrolled in California’s low-income bill support program, CARE, will see a monthly increase of 3.5%, or $1.40, the CPUC said.
