Just starting the thread really, but it looks like a spike is forecast in the next hour or so.

In general the following seems to cause spikes:

• High demand caused by things like a really cold day across the whole country 
• Unexpected demand, like a cold snap that wasn't properly forecast - it takes a while to spin up generation resources
• Power stations or cables linking islands aren't working

Flick general discussion on this thread please. Please keep this thread only for price spike alerts.
