@garethmillerCE Even relatively normal windy days! This year gas has run 100% of the time, and I reckon it sets the price 93% of the time. I agree, and don’t think the carrot here outweighs potential upsides, and there doesn't seem to be a stick yet.

Wholesale CfD consultation is here: https://t.co/sHWMFz7dcK

[Thomas Edwards @NotionalGrid]

@aDissentient I dont think so, as even if RO generators or the nukes took this up there would still be ways to effect the CfD mechanisms.

[Thomas Edwards @NotionalGrid]

Although they are debating including legacy nuclear, which would have a very significant effect. Though not on the wholesale price signal, but rather on the bill.

[Thomas Edwards @NotionalGrid]

Not actually that important IMO, as its only minded to be open to RO, as they were due to begin winding down in the 2030's. Im not sure if this gets to the point of the Govts. ambition to break gas and power linkages.

[Thomas Edwards @NotionalGrid]

And the control room is now even more risk averse

[Thomas Edwards @NotionalGrid]

Independent Investigation into NESO concludes there is no evidence of inappropriate influence over operational decisions and no evidence that control room records were altered https://t.co/4RJ8LSM2F1

[Thomas Edwards @NotionalGrid]

I didnt think ENCC would be thrilled about the interconnector limits...

[Thomas Edwards @NotionalGrid]

minimum margin at 17.30 3.8GW, LoLP of 0.000037, so things look OK but the control room needs some extra comfort

[Thomas Edwards @NotionalGrid]

Another electricity margin notice for this evening, covering a long period 15.00 to 23.00

[Thomas Edwards @NotionalGrid]

NESO has now cancelled the EMN

[Thomas Edwards @NotionalGrid]

NESO issued a Electricity Margin Notice last night for 16.00 to 19.00 today, the wind forecast is due to trough at 16.00-17.00 tonight. Day-ahead prices cleared at £280/MWh, enough to get the OCGTs interested. https://t.co/Xn0MZItvDI

[Thomas Edwards @NotionalGrid]

The de-rated margin looks healthy at 6GW, so no capacity market warnings. The notice suggests control room is concerned about sufficient margins to manage unexpected changes in demand/generation, with 1900MW behind constraints and a shortfall of 1400MW, against their requirements

[Thomas Edwards @NotionalGrid]

Update: the margin notice has been reduced to 104MW of system margin shortfall

[Thomas Edwards @NotionalGrid]

Basically looks like its not windy enough, also Heysham is out on a planned outage and a couple of gas stations have been issuing REMIT notices for today

[Thomas Edwards @NotionalGrid]

Weird news for the day, the NESO control centre has issued a margin notification for the evening, I dont recall a June EMN before(!)

[Thomas Edwards @NotionalGrid]

Update to the cap and floor legal challenge, Zenobe's application has been dismissed, the Tribunal found that the scheme does not constitute a subsidy decision (and also that it does not have authority to review the scheme). https://t.co/PEEqdVEHq1

[Thomas Edwards @NotionalGrid]

This is NESO conflating trading with NIV chasing, which is two different things. If I signal a physical position (i.e. FPN of 100) and spill (i.e.ECVN of 0) then I get paid the imbalance price, but I still have told NESO an accurate FPN, so no re-dispatch needed.

[Thomas Edwards @NotionalGrid]

Good to know that DESNZ don't know how NIV chasing works

[Thomas Edwards @NotionalGrid]

You can't prohibit something you can't do, if I have a BMU with a +ve FPN Flag I can't NIV chase anyway.
