CEC members who generate their own electricity using solar, wind, fuel cells, or hydroelectric power may interconnect with CEC’s electric grid by entering into a Net Metering Agreement with CEC. Net Metering means that the Customer-generator will only be billed for the difference in what the customer uses and what they generate during a billing month. The agreement is a formal contract that spells out the responsibilities of Customer-generator and CEC when customers wish to send electricity back onto CEC’s grid.
