Small and large scale generation connections

Important Notice

Please be aware that we have moved offices and due to construction work still occurring at our new offices there is different addresses for those who are posting applications/acceptances and those who are hand delivering applications/acceptances.

See Step 2 of the “Select a generation connection” tab below for more information.

The connection process policy

With over 1500 MW of renewable generation now connected to the electricity network and in excess of a further 250 MW committed to connect, any potential new applicants should be aware of the current situation regarding new generation applications and the timescales that may be involved.

What you need before you start

The information listed below is necessary to enable NIE Networks to consider and design a connection for any new generation connection application.

Large and small scale generation connections
