Renewables: "talking 'bout my generation"

Quick question.
Is it worth going E7 for electricity when having Solar PV. Seems to make sense, but not quite sure.

Concerning, PVOUTPUT. Notice that it provides an O-ometer:

The left axis shows Os ("efficiency"). The UK graph averages Os across all UK contributors (200 plus) for any day.

Today indicates a combined performance of about .859 Os,

Hi

Take care when looking at consolidated current and previous day's data on PVOutput.

Team & country data seems to be consolidated once per day, overnight in Australia so early afternoon in the UK. The result of this is that recent (current/previous day) consolidated data is incorrect until the next update has been run. Also, due to a number of systems being either batch or manually updated, any consolidated (/averaged) figures tend to be fluid for a while ...

Thank you, zeupater, I can see now that you are quite correct. My "efficiency" (for what it's really worth) clings quite closely to the average UK daily figures. Many correspondents here consistently report far higher than the UK average.

E7 sounds like a good match at first, but generally means a higher day rate, so it might not work. There again, if you use less of the higher priced daytime leccy (due to PV), then it might work.

You probably need to get the prices, try to work out your daytime and E7 import and then 'do the numbers'.

I'm also wondering how E7 prices might go in the next decade, the nuclear fleet is being slowly shutdown, and a lot of the coal fleet won't meet the ever increasing rules on emissions. E7 is there to find (fabricate) a market for unflexible generation, but replacement gas will be rampable ...... but wind won't .... damn .... just when I thought I had a case!

No simple answer.

I think it is.

Have changed suppliers fairly often and always look at advantages & disadvantages based on my own recent use when I do.

Higher day rate not a problem when you're generating much of your own daytime power. E7 pricing particularly useful in winter when generation insufficient to run washer, dishwasher etc.

But you need to run your own historic data through a spreadsheet rather than relying on advice.

Hi

That's all down to the roll-out of smart-meters. I don't expect there to be much fuss until the smart-meter rollout is well down the line, after all, the industry wouldn't want to upset consumers enough for the government to slam the brakes on the highly lucrative £12bn project .....

As soon as smart-metering market penetration has reached 'critical mass' the industry will whip-out the margin-sticks and beat us all with them ... carrots eat into profits where sticks bolster them, so even if there's initially an orange coloured sweetener, you can almost guaranty that they'll be withdrawn as soon as an excuse can be found ....

So, the future of E7?, well it becomes redundant. Why allow consumers to budget and plan their usage according to fixed periods when there's the ability to charge different rates for up to 48 different periods per day according to variable demand, with no predetermined pattern?. Now then, just think about what this does for customer inertia and loyalty - how does anyone plug an unknown future half-hourly usage pattern into a system with unknown half-hourly tariff patterns and get a meaningful comparison between suppliers ?? .... Job done, Ofgem look like bigger idiots than usual (not that they'd realise it for a couple of decades or so ) customer confusion rules, margins tweaked accordingly, administration savings pocketed and we're all paying for the privilege of having a highly paid, but relatively dim, civil service.
