The new influx brings Pacific Gas & Electric’s total contribution to Proposition 16 to about $46 million. The ballot measure to require a two-thirds vote by local voters to start community choice aggregation programs is set for June 8. According to records from California’s Secretary of State, PG&E donated $2 million on May 24, $6.5 million on May 21, and $3 million on May 19 to sway voters to pass Proposition 16. The utility also donated about $166,000 between May 5 and May 7. PG&E is one of only two contributors to the Yes on 16 effort. The California Chamber of Commerce’s political action committee donated $91,000. Opponents of the measure have contributed about $90,000 to fight it to date.
