I guess the Guardian expects to be using this visualization a lot over the next few years.

Hadn't considered that angle, thanks for detective work. Good to hear that a quality paper would bother to do that - rather than just take an "oven ready" press release from someone standing to benefit Smiley

Sorry, didn't describe myself properly.
My expectation is that the Guardian wouldn't be bothered to create a Widget so that the graph auto-updates ... but just just bung a JPEG in the page. (I could be wrong on that of course ...)

It's an SVG. If I were them, I'd just have a cron script that ran hourly to update an underlying data file on the server from the bmreports API, build the SVG code from that, then cache the page.

They do the building of the SVG data set within the local browser as it allows them to modify things like the hight and width based on the users' environment.

Of course, whilst it's good to reflect that we've gone almost 2 weeks without burning any coal, we are still generating 2GW of power at Drax by burning wood chips - essentially the rare steak equivalent of coal - so it's not as clear cut as it looks is it?

If all users of immersun and similar Fit Fraud PV divertor devices switched them off, Then less coal, gas and woodchips would be burned in electricity generating plants! As a consequence you would have to burn and pay for some extra gas and oil to be burned at home.

How very true, and your point is?
Very difficult to beat point of use/just in time devises but i do see that using a high end source of energy such as leccy to just heat water, the lowest form of energy, is not perhaps the best use of leccy. If that is your point.

As an owner of an ImmerSUN and an export-reducing battery I can tell you that my SolarPV system very often still exports to the grid. My modest array will still generate excess power to cover domestic demand, battery charge and hot water heating.  The local network still gets the benefit of my green electrons on most sunny days. If itís not sunny then the SolarPV doesnít generate enough to export but then thatís the inherent problem with solar anyways isnít it?

Surely itís better for there to be people with solar and an ImmerSUN type device than not to have solar at all?
The ImmerSUN widget was the literal deciding factor in me getting my partner to agree to the SolarPV in the first place.

The below factoids are copied form the National Grid Twitter feed announcement

The month of May has also been a record setting month for zero coal

GBís first ever week without coal
First ever 100 hour run without coal
More hours without coal than in January, February and March combined
Over 624 total hours without coal (more than all of 2017)
Plus coal free fortnight

Which has led to a 53.1% decrease in carbon intensity over the last five years

Immersun and similar devices are not and never have been FIT fraud devices and it is mischievous or worse to say that they are.  FITs have always been about generation.

You might be correct if you had referred to export.  But I would argue that my supplier paying me the 3p plus inflation rate for my export and selling it to my neighbour for 15+p is the bigger fraud.

I am sure that it would be very simple for the rules to change so that all export is measured and smart meters are to be used even in the dumb mode.

Rather disgusting post.

If diversion devices tip somebody over the edge into getting PV, then there is a net gain with PV displacing some FF leccy and FF DHW. Anything that improves the economics of PV should be celebrated not smeared.

During non space heating periods I doubt gas boilers are achieving much more than 50% efficiency, especially after accounting for heat loss in the internal pipe runs which is now no longer a space heating benefit, so replacement leccy generation from gas at 50% efficiency would seem to roughly balance out anyway.

If there is any concern about export v's export payments then I'm sure the companies would complain, but since most PV'ers export more than 50% of generation, I somehow doubt they will want to make a fuss.

I really don't see how spreading old (very old) anti-PV propaganda helps anyone today, I'm a PV'er, with no diversion, on the low export rate, that exports approx 70% of annual generation. For May my generation was 678kWh and my export was 547.6kWh's, I will be paid for 339kWh's and I (clearly) have no issue with PV complimentary technology.

Additional note: my May consumption of leccy was 214kWh, a bit high, but due to quite a bit of ASHP use in the early weeks when we had very cold air temps. During that period when the COP was probably 3 or 4, we didn't need to use the GCH at all which is a good thing since it would have been around 5x less efficient.

I generate so much green energy that if I switched my Immersun's off then my export limitation device would throttle back the generation and the green energy would be wasted.

The immersun's also allow me to turn off my gas combi boiler completely over the summer months.

My hot water is heated entirely by either tiny woodburner (i think 1kw to back boiler) or surplus diverted electric (Solis not immersun -more efficient).
Surely this is better than importing electric from gas or coal generation ??

My system sucks up 98% + of what it generates to battery for overnight use, elec for car or HW in that order. It cost me alot of money so if the rules allow me to not export all the excess, then so be it. If I was only paid for export, I may have decided to set if up differently or not bothered at all. £25k towards a RR v8 sport might have been more fun but also more damaging for the environment,

Change of tack. I believe we are now seeing the first effect of EVs being charged on E7 ref https://www.bmreports.com/bmrs/?q=eds/main  and "system demand"

In the period midnight to 02am the graph used to decline and continue a smooth curve down but the lasat yr this smooth curve takes a abrupt lessening and even runs close to horizontal and this is particularly noticeable last night/this morning helped by the fact the vertical scale of the graph has become larger.

The low Sunday/Monday night predicted to be 17.1 Gw  is this a new low -could be.
