A few batteries to help self use more would surely solve that issue.

Yes, yes it would!

Re: Octopus Tariffs
Maybe need to tell him/her that modern batteries are a different chemistry and don't explode or burn like EV car ones? - apart from Tesla Powerwalls, I believe!
p.s. I find a lot of prejudice against "this green crap" and have decided that it's basically only financially switched-on friends and acquaintances who are prepared to look at the figures and accept that it's worthwhile - and some have joined in too!

Re: Octopus Tariffs
It's an odd one.
The boss drives a Tesla and he has solar on his current house. He was totally up for putting solar on the office building.
He's currently building a self-build to PassivHaus standards and it will have 12kW of solar on the roof (3-phase supply!) along with a ground source heat pump for hot water and lots of other cool environmentally sound tech. But at that point he stops and doesn't see the point of batteries on a building.
At least not yet anyway.

Octopus saying they'll switch our business tariff to Shape Shifters on Friday. Be good to see what effect this has on our energy bill...

Re: Octopus Tariffs
Ok so as a company we're now on Shape Shifters.
The standing charge is £1/day less than before (£2 rather than £3), so that's £365 saved per year straight off the bat.
Previously we were paying 29p/kWh at all times.
Peak rate is from 4-7pm, and is higher than before (34p)
But the regular day rate is 17.3p (so 12p/kWh lower)
and the night rate from midnight to 7am is 15.5p (so 14p/kWh lower)
So let's see what happens!

Re: Octopus Tariffs
Dan,
Now you need batteries to get you through the peak tariff period if required, depending on usage it should be a smallish battery and easy to cost justify .

Re: Octopus Tariffs
I'm in the interesting position as an Octopus Go customer that when the new tariff changes hit on the 1st April, their calculation is that I'll be worse off!
Basically most of my consumption is in the 4 hour 9p window and despite the other 20 hours reducing in cost slightly, my minimal consumption in that period is offset by the considerable increase in standing charge.
Don't have an alternative really and the increase isn't huge but still unwelcome.

Re: Octopus Tariffs
Do octopus actual look at users actual consumption when they estimate your usage?
On my email highlighting the impending drop in peak rates, they estimate my annual consumption as 3900 kWh. I used over that in January this year and last year’s annual consumption was 20 MWh
