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.

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.

And the control room is now even more risk averse

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

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. bmrs.elexon.co.uk/events

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

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). catribunal.org.uk/sites/cat/…

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

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.

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.

£370mn for 850MW is about £435/kW, which you could buy a new recip gas engine or most of a new OCGT for.

If we assume it has 10 years left (built in 2010) of CM payments left I think it would need £60/kW each year at an 85% de-rating factor to make back that £370mn. Which seems like a reasonably achievable outcome, with other revenues paying for Gas and Network charges. a
