This bill authorizes municipalities and groups of municipalities to establish community choice aggregation programs. Under a community choice aggregation program with a plan approved by the Public Utilities Commission, eligible customers are automatically enrolled in the community choice aggregation program unless they choose to opt out. The bill establishes requirements for customer notifications and protections and directs the commission to adopt rules for community choice aggregation program authorization, standardized opt-out procedures and consumer safeguards. The bill also requires electric distribution utilities to implement a purchase of receivables program requiring utilities to purchase community choice aggregation program receivables at a discount rate approved by the commission, consolidate billing, assume collection responsibility and report to the commission annually.
