Oxford Community Electricity Aggregation (CEA) is an electricity supply program organized by the town of Oxford to provide residents and businesses with new, Town-vetted options for electricity supply. The delivery of electricity and billing for use is still completed through National Grid, so customers continue to receive one bill from the utility.

Oxford CEA has a standard product, called Oxford Standard; participants in the program receive Oxford Standard unless they affirmatively choose the 100% renewable energy product called Oxford Premium 100% Local Green.
