Del Mar sets default rate for CEA customers Del Mar City Hall March 17, 2021 7:53 AM PT Del Mar will offer Clean Energy Alliance customers 50% renewable energy that is 75% carbon-free as their default energy supply, which will provide a monthly savings of about 61 cents for residential customers who currently have a comparable SDG&E plan. When the CEA launches this May, residential and business customers will also be able to opt into a separate 50% renewable energy plan that offers slightly more of a discount, or a 100% renewable energy plan that would cost a little more, relative to customers’ current San Diego Gas & Electric bills. Customers can also opt out of the CEA and continue receiving energy from SDG&E, which will continue to provide the infrastructure used to deliver energy for CEA customers.
