I agree you might have to tweak the system a bit. If a 'call unit' is turned down by the generator because of sudden unexpected failure, for example, you could hardly expect that to be fixed in just half an hour. So a call unit could perhaps be rolled over for a period of say 3 continuous months, until the faulty part was fixed. All that would still count as a single 'call rejection'.
Only allowing three turn downs a month is low, yes. But this is to encourage seamless system use. Allowing no 'call unit rejections' at all would be going too far the other way.
Drawing the line between what is a drought and what is vague and grey. The drought rules have to reflect this reality
Base case seasonal price variation will be based on historical records averaged over the last five years, from the current bid ask system.
Vaygor, you know I would never give away my source. The journalistic ethic would not allow it.

Without quoting the above source, I can't gauge the credibility of its originator, and it follows that I cannot therefore gauge the credibility of the content.
This article http://www.3news.co.nz/Labours-power...4/Default.aspx published in mid April is on the mark. In the article, David Shearer is quoted as saying "I'm not going to talk about the policy at all...I'm not going to give an explanation of the policy. We are working...according to our own timetable." and I have not seen a shred of clarification from Labour since on how they might do this. Until they come out with something, Labour's 'policy' cannot be deemed to be any more than empty political posturing.
Given the variables of weather, seasons, demand, outages, and growth, dictating electricity grid injection prices by way of any mechanism other than natural competition and supply-demand forces utterly defies logic... well, unless we resort (by definition) to a dictatorship/communist regime.
A wealth of information and data on the existing system and set-up can be found at http://www.electricityinfo.co.nz/comitFta/ftaPage.main
This link should provide some insight into the complexities of the issues and what is currently involved. On top of this the site says it is only a subset of WITS (Wholesale Information and Trading System) and that it only provides a "small taste of what is available to our subscribing WITS clients".
Further to this, WITS is only one segment under the Electricity Authority. Refer https://www.ea.govt.nz/about-us/ which is another good source of information about the structure of Nw Zealand's electricity industry.
When I think about the Labour/Greens sitting around trying to reach agreement with each other and nut this 'policy' out in the event they are voted in, I laugh so hard as to nearly wet myself.
