The Clean Export Guarantee (CEG) is arranged through your electricity supplier rather than through SEAI as a separate grant application. Your registered electrical contractor normally submits the required NC6 notification to ESB Networks, and you should receive confirmation that the installation can export electricity. You can then contact your supplier to ask how to register for its CEG payment process and provide any documents requested, such as your export connection details. Payment arrangements may depend on your meter, supplier and system, so check the current terms directly with your supplier and ESB Networks.
