Capacity sales through Implicit Allocation

We may offer for sale up to a maximum of 75% of IUK's technical capacity through implicit allocation. Currently, annual, seasonal and quarterly unbundled capacity products may be offered via this mechanism.

Implicit allocation will run when the CAM NC Auctions are not taking place on PRISMA. A three month forward view of sales dates via this mechanism is published here.

The IA Guidance Document provides details of the capacity products which may be made available.
