Community Choice Aggregation (CCA)
A program where a local government purchases electricity on behalf of residents, often choosing a greener energy mix than the default utility, while the utility still handles delivery.
Why It Matters
CCAs operate in California, Illinois, New York, and other states. They can provide 100% renewable energy at competitive rates without requiring you to switch your utility.
