No surprise - have you seen the wholesale market prices for that time tomorrow?!

In theory the test events aren’t in any kind of reaction to wholesale prices are they? That’s only for live events?

If you have to schedule a test - why not do it when the benefits are most useful?

Plus they can still continue to claim "we have not needed to activate this service", a useful political message to argue against indicators of shortage.

I’m surprised we’ve not seen a test on a weekend - because the maths gets harder there with only using 4 days (and maybe even then the median two of those 4 qualifying days?)

or an “emergency” test with on-the-day notice.

For this test am I correct in thinking the maths and qualifying in day use mean that potential savings are double?

Is there any chance they could change the way things are calculated or is that fixed for the whole trial? 

Specifically the IDA.

I'm in again. Ready to charge batteries, run the washing machine and then finish work (I work from home), turn off the PC and unplug the laptop by 1655. A two hour session is a bit of a departure, let's see how we go

It seems that the calculation is written directly in the National Grid description of the service - so they could change it, but that would mean revising the complete service.

To maximise "savings" is the key period of useage still 4-1 hours before the event? Or does the fact its 2 hours make any difference?

Same period.

Yeh I think so. so long as you cut down for the full 2 hours (4 periods!)

There is a new session tomorrow, got prompted on the app an hour ago.

I don't think there is likely to be an "emergency" test period with on the day notice. Simply because that is not how NG operate their DFS (demand for service) notices. You know how at the end of November we nearly had a real event that wasn't a test? If that hadn't been withdrawn, it would have been the "emergency" test. When NG issue a DFS, they issue a "standby" the day before it is required which has fairly wide parameters. This allows preparation for an event. They then keep processing the data and decide whether they really need it or not and issue a confirmation or a withdrawal. That confirmation can be quite close to the event, but it shouldn't be a surprise because of the previous standby notice.

The DFS is something that has been running for many years. It is only recently that NG have started trialling its expansion to domestic supplies, so we hear more about it.
