Overview
Municipal aggregation is the process by which a municipality (meaning a town or city) purchases electricity in bulk from a competitive supplier on behalf of the residents and businesses within the community.
In a municipal aggregation:
- A municipality will procure competitive electric supply on behalf of participating customers
- A municipality may join with other municipalities to procure competitive supply
- Customer participation is voluntary. The municipality will provide customers an opportunity to opt-out of participating in a municipal aggregation program. Customers who do not opt out will be automatically enrolled in the aggregation program, but may opt out at any time after that.
- The electric utility company will continue to provide electric transmission and distribution service to participating customers
How does a municipality create a municipal aggregation?
A municipality must:
- Vote to initiate the municipal aggregation program
- Prepare a municipal aggregation plan in consultation with the Department of Energy Resources, often in partnership with a consultant
- Allow an opportunity for citizen review of the municipal aggregation plan
- Submit a municipal aggregation plan to the DPU for review and approval
