This is the home of Empire, the exciting new auction and nomination platform from BritNed.

Empire is a new trading and nomination platform we are developing to deliver the functionality, reliability and flexibility that our customers deserve. Drawing on over a decade of operational experience, Empire will be a market leading platform that will set our customers up for success today and in the future.

Once live, Empire will be the single platform for all BritNed activities and we will no longer be using the Electronic Capacity Allocation Tool (eCAT), Regional Nomination Platform (RNP) or Kingdom system.


If you currently only participate in BritNed auctions via eCAT (JAO) and haven’t signed a BritNed Participants Agreement, please contact to discuss what needs to be completed for registration. You must complete this before the transition to Empire.


All of the Empire developments, information and contact information can be found below.

We send out emails to all our customers to let them know when these pages have been updated. If you can’t find what you are looking for, at the end of this page there is a link to our support page for FAQs and contact details.
