Transmission capacity conversion

A customer who has been allocated non-coordinated transmission capacity based on a contract entered into prior to 1 November 2015 can convert such already contracted capacity into coordinated capacity. Capacity is converted based on the customer's application and the successful booking of new coordinated capacity in an auction.

In accordance with Article 21 NC CAM, the service is offered for annual, quarterly, and monthly transmission capacity.
