Yes, you (and your installer) will receive an auto-response email confirming receipt of your documents. Once all of the forms associated with my application are submitted, how long does it take to receive approval from SCE&G? Within 15 business days from receipt of your completed application forms and fee, you (and your installer) can expect to be notified with the outcome of the technical review. We will contact you (and your installer) by e-mail.
It is important that you wait for approval from SCE&G to ensure your system plans adhere to system requirements for the interconnection process.
The South Carolina Interconnection Standard requires that customers “obtain and retain, for as long as the Generating Facility is interconnected with the Utility’s System, liability insurance which protects the Interconnection Customer from claims for bodily injury and/or property damage.” The Standard also prescribes the amount of liability coverage for residential and nonresidential customers based on the size of the Generating Facility.
We do not partner with solar installers or leasing companies to sell products or services to our customers. We provide interconnections services to our customers and work through solar installers (at the customer’s request) to help facilitate that process. Claims that SCE&G is working with solar installers to sell rooftop systems or leases are not true, and should be reported to the SC Office of Regulatory Staff or the SC Department of Consumer Affairs.
