Auction Management Platform

The Auction Management Platform (AMP) system is a computerised system that provides the necessary mechanisms and outputs to facilitate trading across the Moyle Interconnector and the East-West Interconnector. The AMP is an interface between the SEM in Ireland and the BETTA market in Great Britain.

Capacity within the interconnectors is allocated by auction, to capacity holders to enable energy trades to take place across the interconnectors. Both capacity allocation and energy trading on the interconnectors are facilitated by SONI via AMP, which is compatible with both the SEM and the BETTA arrangements.
