BritNed developed and operated the Empire digital allocation and nomination platform used to manage access to capacity on the BritNed GB–NL 1,000 MW HVDC interconnector. The project website described Empire as an award-winning, next-generation single-window system intended to provide customers with functionality, reliability and flexibility for interconnector trading. Empire enabled market participants to take part in long- and short-term capacity auctions, manage nominations, view settlement summaries and generate comprehensive reports within the same platform. BritNed also stated that the platform supported the “Buy Now” Dutch-style auction product, which redirected a portion of Intraday capacity into a mechanism allowing participants to acquire capacity closer to delivery, including up to minutes before the Nomination Gate closure. BritNed reported that Buy Now was developed by BritNed and enabled by Empire, and that Buy Now 2.0 was released in April 2025, introducing custom capacity requests and replacing the previous fixed 5 MW capacity blocks. This indicates an ongoing digital systems capability supporting auction operations, nomination management, settlement and reporting for the operational interconnector.
