 I was thinking of writing my own app.  But perhaps I need to check theirs out again.

Just FYI - Power is around 1c/unit at the moment if anyone wants to take advantage of the savings - check out http://em6live.co.nz

That's the national rate. With margins, without GST, it's 7.7c/kwh in Wellington. In Wellington the line charge is 6.4c/kwh and Flick charges 1.5c/kwh. Off peak the line charge is 3c/kwh. Last night power prices were very low as well, so I was probably paying 5c/kwh to heat my hot water, and same tonight :)

Worked out good for me.

A similar price to Natural gas. Which of course annoys me as I can't get Natural gas where I live. Im also on the Flick "Smart plan" So more expensive power during peak times. But really cheap during offpeak and all day weekends. Im in the North Shore, Auckland. Therefore Peak / offpeak is definitely not a default plan, and Night rate is not available.

 

Also because I have everything possible on timers to keep my peak usage low. During that last price spike, my bill only went up by $2.54

Having 'Flicked' over at the end of May, I'm happy with the savings. Even with the spike a couple of weeks ago early indications are we're saving about 1c/unit based on the past 12 months with Powershop or about 2c/unit if looking at the last Powershop billing period only. No changes in usage habits either (yet).

Kraven, and what is the absolute price number for the Flick? (I'm waiting my last bill with genesis before I'm ready to switch as well)

I really hope it works out over July/August for you guys. I haven't read anything positive with two generation plants now out for winter.

 

The highest spot price in 3 years doesn't sound something to be excited about:

Good think about Flick is no contract. Last year winter prices were super low because it was wet, therefore lots of hydro available. Guess we wait and see what this year is like with the plants out. Is it the big plants out or smaller ones?

Otahuhu saw just over 400MW retire before Summer. That's a fairly huge contributor in the north.

 

Southdown sees 170MW gone from the Auckland area.

 

Both were big causes in the under-supply in the North Island the other week.

 

The HVDC cable I think only handles 1,200MW and most of the time it's 800MW during a normal day's peak output and winter hasn't ramped up yet.

 

http://www.em6live.co.nz/PlanningRegion.aspx?planningregion=lsi

 

If you look at the reserve capacity from the South, yes there is some, but when you factor the HVDC's capacity it's not a lot more than it is now after you take away near 600MW for lost generation up north.

 

It will be interesting to see.

And whilst it's cold tonight down south, it's not as cold cold as it will be starting on the Weekend when the south chews up it's generation capacity.

It'll be interesting to see what happens. Since I moved my hot water heating to a timer, and of course dishwasher and where possible clothes drying to off peak, my peak energy consumption has dropped quite a bit. The bill hasn't gone down by as much as I expected, but in a few months or at the end of winter I'll do some calculations once Flick can supply data. The % saving has definitely increased since I did the hot water timer, and it will become even higher if peak prices rise.

Is this because you make the major savings just being on the market price?

For me a lot of the savings I'm getting from moving to a peak / offpeak plan are from overall lower lines fees. Also lower average peak usage meant the last big spike only added about $2.80 to my bill.

As for possible overloading issues. Transpower have said that the central north island bunnythorpe to mataroa power line will probably overload first.

Generation wise, the TeMihi geothermal station opened in 2014. So average capacity utilisation of the thermal power stations was only around 35% so some needed to close. No surprise that the ones on expensive Auckland land were the ones that were closed.

I was meaning the bill after fitting the hot water timer that moved water heating to between 2am and 7am. I was doing quite a bit of the water heating off peak as we're up early, so most of the morning water heating was done before the 7am switch to peak. However evening showers, dishwashing, and weekend clothes washing are all now shifted to off peak.

 

I did a fairly thorough analysis, which suggested for my water use at the times I typically use it my savings would be between $170 and $212 for the years between 2009 and 2014, and $139 in 2015 - I have a lot of historic market data. However because power prices will be higher this year my savings moving to off peak will increase.

 

Here's after my timer switched on, typical day

You can see a lot more power usage during off peak times. In the middle of winter, when power prices are high at peak, this will help more.
