Abstract: Techniques for authenticating and authorising authorizing user access to a component of a power plant within a private network of a renewable power plant having wind turbine generators. One technique includes providing at a local computer system in the private network a list of credentials and authorizations representing a plurality of identifiers and authenticators of users and corresponding access authorizations. The local computer is in direct communication with components of the power plant and is configured to receive a request for access from a user via a computer interface in the component in the private network. If the requested access can be granted by consulting the list of credentials and authorizations, the grant is communicated from the local computer to the computer interface in the component, and in case access cannot be granted, a request for update of the list of credentials and authorizations is communicated from the local computer system to a central computer system outside the private network.
