Manual: Create an account: register your organization on GOPACS (for CLC-A and CSC-A)

After entering into a capacity steering contract on request (CSC-A) or a capacity limitation contract on request (CLC-A), you must register your connection in GOPACS. The grid operator will then link your connection to the contract so it can be called off. When this happens, you will receive a notification at the email address you provided during your GOPACS registration. This guide explains step by step how to register.
