if it is weighted towards daylight hours and/or it includes EV charging that could be scheduled to suit.

He said he had a home lab, so it's a pretty consistent 24x7 load. I'm in the same boat..

Okay. Sorry, I wasn't familiar with the term but just sussed it out.

Round figures that sort of consumption would require ~20kW of PV based on our own generating potential but to spread its use over 24hours would require substantial and probably prohibitively expensive battery storage, or a couple of V2G enabled EVs.

ETA: Worth noting that Octopus have a 18c Off peak (night) rate and a 17c solar export rate so quite an economical way to load shift your consumption.

What would 20kW of PV cost (including installation onto a tile brick roof) & how much roof space would be required?
(non battery system )
I'm guessing you would be able to offset about 25% of power useage. (nothing at night, 30% load during shoulder hours and 100% during the peak 4hrs of the day....)

FailedWOF:

Check the Flick Electric Off Peak plan. I also have a large home lab that's one third to half my consumption.

Usage over the previous 4 weeks: 2620kWh / $498.48

Sweet, that was the kind of tip. I was after,

Sounds like we have similar sized 'hobbies' 😁

I've just run the numbers and interestingly both plans are quire similar for home labs.
$545.36 Flick Energy Off Peak Plan
$539.19 Flick Energy Standard plan

(it also looks like Money Hub have a $50 referral,
Unless you have one I can use @FailedWOF

(sheesh, you just reminded me, my Car WOF is due!.....)

Anyone know what Flicks 'Business Pricing' is like - it's not detailed on their website - looks like you have to talk to someone, but an indication would be handy....

I wish these power companies were required to quote the prices inc GST by default, considering most people are residential consumers so have to pay GST.

Yes. Also, there should be a number of mandatory default plans defined by an appropriate regulator so that consumers can actually compare providers without having to spend hours plodding through a spreadsheet.

Been very happy with Flick Wholesale the past few months. Only had one or two instances where prices spiked to 40c/kWh but I have some automations setup to drop load when price gets high. Overnight I can be paying only a few cents (just network charges) owing to the low spot generation price.

A lot of people left flick because wholesale rates were quiet high for quite a long time. That's the risk you take when you're exposed to wholesale power prices.

How long have you been on Flick Wholesale rates?
(it no longer seems to be an option according to their Website)
Is Wholesale better during the Winter or Summer?
- Overall do you think its worth while?

20kW is a significantly large PV installation and assuming 500W/panel that's 40 of them so more roof space than most domestic dwellings would have. A reputable PV installer would be better placed to advise on your situation. Also most (if not all) lines companies have a 10kW maximum (5kW/phase) export limit and gen-retailers require wholesale pricing beyond 10kW. Again a question for your installer, including the viability of battery (or V2G) storage.

So far as the self consumption stat's are concerned you will be generating more than you require during peak sunlight so that will be exported. The near equivalency of Octopus's night and export pricing is a good fit in this regard as that makes for the grid being a very efficient 'storage' method and close to self consumption economically. The downside would be shoulder hours or overcast when generation is meagre and offpeak or peak rates would apply to imported consumption.

Lots of moving parts so to speak and a considerable capex (I'm guessing $40-50K) so you're best placed to investigate further if it sounds feasible.

I signed up for Mercury in March this year at 14.88c / kWh + GST fixed rate for 2 years.

At the time we were moving from Contact who had been regularly putting up our rates and didn't have transparent pricing for their plans available.

Now the weather has warmed up a bit and we don't need to heat the kids' rooms at night our usage averages out to about 6 kWh / day.

Octopus Energy are not having a good day.. I've had two "We've been notified you'd like to switch retailer" emails in the last 20 minutes.. rang them after the first one, the contact centre guy was "yeah someone did a thing and everyone got sent it" ..

ronw:

I am also interested in companies that offer a period at night for reduced or cheaper electricity for charging cars or washing and drying clothes etc

Meridian have an EV plan that provides this.
