Off-Target #2 = Unit failed to start – Braemar A3 on 29th August 2018

As part of the process of compiling our Generator Report Card 2018, we’re taking a look at the instances where individual DUIDs were significantly Off-Target.  In our longitudinal summary article today, we can’t see a clear trend emerging to suggest the overall aggregate absolute level of Off-Target is getting substantially worse, or better.


One of the reasons why a generator might be Off-Target is that it might have failed to start.

Using “Time-Travel” in our ez2view market analysis software, we’ve wound back a particular dashboard in ez2view back to the 17:00 dispatch interval on 29th August 2018, in order to show an example of this:


As noted in on the image, the unit was dispatched but failed to start, as a result of which a rebid was made to remove capacity from the market temporarily:


What’s of particular interest to us in our Generator Report Card 2018 is to explore how frequently this type of thing occurs, and whether the incidence has changed significantly.
