Looking back through the thread, I see most people are quoting total bill / units used.  For me this was $30.44 / 114.9 = 0.265 cents (Christchurch low user.)

Last week I paid $74.13 for 353.43 units in Wellington. This is 21c/kwh inc GST and daily charges. On Genesis (picked at random) I'd have paid $94.50, according to my calculations (19.89c/kwh, $1.71 per day, both plus GST).

 

The floating prices keep going up, and up, and up. At least they go down a bit over night. I note though that on Friday the price at midnight was higher than the price at midday, and the price 6-7am is much higher than it used to be - higher than 1-3pm. I'm probably going to change my hot water timer to work 2-5am and a boost 2-3pm.

Pricing over the last 60 days.. 

 

Yellow is the spot, green is once daily costs are added into the mix..

 

You can see a small upward trend, but as others have said overall still cheaper based on previous plans.

Haha. Yip, could be. There is a bit of rain about but in this front unlikely to be enough to make any significant impact.

 

 

The snow pack is now establishing for the season, So storms from the south will have a fair chunk of their precipitation locked out until the spring thaw, ( Big NW systems excluded)..

Wellington low user - $39.07 for 132.15 units, so 29.56c per unit.

 

Overall savings are at 23%, but this week it was down to 5%.

Well that rain certainly made a difference. South island inflows are now above average for this time of year. Currently between 50 - 75th Percentile. And looking at the non response schedule for the next 24 hours. (forecast spot prices). They are definitely forecast to be alot lower. 8.6c/KW/hr OTA_GXP 10cKW/Hr BEN_GXP overnight tonight. Peaky throughout tomorrow, usual morning and evening spikes. But even lower after midnight tomorrow (16/6th)

 

Back to electric heating for me tonight. Prices will spike rapidly starting at 6.30am Thursday morning (15/6th). Spiking to around 16c, So make sure you set a timer if using electric heaters tonight.

 

All of the above prices are raw wholesale, so add on your lines fees and GST. Go to https://electricityinfo.co.nz to get these prices for yourself if interested. Turn on the NRS schedule.

Didn't seem to make any difference to prices here in Wellington. 25c/h at peak. Could be worth though, it's a cold day.

The rain event that rolled through was pretty minor and you'll unlikely see any shuffle of the generation profile until there is a significant shift in lake levels (i.e. a huge event) occurring. The Uncontrolled storage in the SI (Te Anau, Manapouri and Hawea) are all still very much empty or towards the bottom of their operational ranges.

 

The good thing is the Te Anau, Manapouri and Hawea catchments are moist, so any rainfall will likely roll straight into the lakes. However again you won't see a change in profile until a massive event rolls through (think 150 - 200 mm over a two day period) and fills the uncontrolled storage up.

I'll take 25c at peak any day. We were over 42c for peak this morning and even now at 1124 our rate is 39.1c.

We're at 31c + GST right now, in an unusual midday peak. It hasn't gone below 25c all day, as far as I can tell. Based completely on observation and no hard data, it seems like the average price is rising every day.

 

Flick is $1.70 per day plus varying at the moment between 14c and 40c per kwh. Electric Kiwi is $1.63 per day, 16c/kwh, less one free hour of power. All plus GST. Electric Kiwi is cheaper for us right now, but only because of the free hour of power. It also removes the need to care about power prices, try to avoid using power when you really need it like when cooking dinner and during the evening.

 

I'm not far from switching just so I don't have to worry about the power prices.

Faffing over spot prices, installing timers etc etc would do my head in. Not doing this is surely worth something? It is to me, anyway.

 

Am thinking of switching from Mercury to Electric Kiwi but don't anticipate a great saving, except for the guarantee for the first year!

Most of the year Flick is 25 - 30% cheaper than standard power companies for me, with few to no downsides. With the low rain / storage lake levels and cold weather prices are higher and spiking more often.

 

The long range weather forecast gives some hope that normal winter rain levels should restore in the next week or two.

 

If we don't see some kind of change in the next week I'm pretty sure I'll be changing. I may get sick of watching power prices before then and change anyway.

I guess you are looking at the inflow chart on the daily security of supply updates. These are only daily inflows (3 day rolling moving average), so not that relevant in terms of setting price, unless they are off the chart high. They'll be back down to zero again by monday given the forecast. You might find storage the more relevant thing to look at. 

 

https://www.transpower.co.nz/system-operator/security-supply/hydro-risk-curves

 

When storage hits the red line there will be a public conservation campaign, and retailers will have to start paying customers a compensation fee each week (not those retailers with spot tariffs though -- I'm not sure why). Meridian, who control the south island lakes have requested that Transpower move the line down because they don't think it would be a good look for the industry to have a conservation campaign in an election year. If they are successful prices might not go too high, but if not they'll want to raise spot prices to try and avoid that outcome. In which case 20c might seem pretty cheap.

Wow, for the first time since 6am the price of power fell below 20c/kwh + GST. This is the worst day so far. I know we look at big picture, but changing power companies is easy. I'll probably still give it a week or two, but I'm getting really sick of constant notifications from the Flick app, and having to keep an eye on the power price. 

 

Do other suppliers pay less than the market rate for their power, through say bulk deals? Or do they all pay the floating rate all the time?
