What a pity that gov reports get published which people fail to read before spouting off

If they had read the report they would have picked up  "13.0 GW of renewable electricity projects are consented and in the pipeline for development.  1.2 GW on these are under construction, most of which are offshore wind farms off the Moray Firth."  and then there is the Scotish Islands and more onshore.

Scotland is no where near the end of this journey which for them is a serious income stream which they need for their independence ambitions after the decline of oil and gas income and subsidies from England.

Once you have more than net 100% leccy you move into leccy heating and green hydrogen which is already beeing done in the Orkneys.  Hydrogen/electric ferries,cars etc

Just as an aside - I just checked Gridwatch (others are available  Grin) And given the current situation we've got Wind at 40% of eleccy (10GW). 40% !!. As the sun comes up and should give maybe 6,7,8 GW today, we should see something like 70% of electricity from Wind and Solar for a few hours.

Yep, currently only 38% of demand being met by big old-fashioned kettles (gas, nuclear, biomass) - the rest from more modern, post-fire-age wind, solar, hydro; plus a bit from interconnectors.

It's only a small number of years ago that doubters were saying that renewables proponents didn't understand inertia, and that the grid just couldn't go with less than 50% synchronous supply. And now the grid routinely goes less than 50%.

Looking at the EDF website it looks like we should have about 1.5GW of nuclear coming back on line in April too - if this shutdown carries on for a while with its suppression of demand continuing, and the weather continues to improve with spring here and summer on its way, the proportion of zero carbon generation on the grid could be getting to 75% or more?

Spot on. Critics focusing on the other energy demands before RE leccy has expanded to the point that it has displaced those too, is somewhat baffling to me. What I see is a nation proving what can be done, and setting milestone after milestone.

As an example, I love my BEV, and rolling them out at a rate where their additional leccy demand is less than the additional RE leccy each year seems to make more sense than doing it the other way around and burning ever more coal! I also assume that if BEV's could be rolled out faster, then Gov policies would (attempt to) scale up RE capacity rollouts accordingly.

I only wish Wales and England were competing with Scotland, but so far we aren't even in the same league.

Obviously it goes without saying that actual generation will need to exceed 100% to account for storage losses, and acceptable waste/spill/curtailment when that option is the most economic.

Very clearly.  At times wind generation, for the whole of the UK, has been far below 1GW for hours on end.

Well that's a downer, I didn't know that.

In that case I guess the UK's plans to rollout 38-40GW of wind capacity, and nothing else, might not meet 100% of demand 100% of the time. That is the plan, right?
