Replacement Reserve (RR)
Replacement Reserve is a harmonised service across participating European TSOs for the provision of both an increase and decrease of active power.
Prior to offering capacity for RR, participants must successfully prequalify their assets by providing technical and operational details. As part of this, participants are also required to accede to the CUSC.
Once participants have prequalified, they will need to register their assets with Elexon as part of the BMU registration process.
Once this has been completed, participants are able to offer capacity from their assets for TERRE from December 2019.
This below document contains guidance on how to complete prequalification for Replacement Reserve and Wider Access.
Overtime, an FAQ document will be shared and regularly updated to provide further clarification to participants on the prequalification process.
