From BBC Climate yesterday:
Renewables can generate significant amounts of electricity when conditions are right. On roughly a third of days in 2025, at least half of Britain’s electricity came from renewables, according to BBC analysis of Neso data. https://www.bbc.com/news/articles/cz947djd3d3o
How did Scotland do in this record-breaking year? Match the UK’s third of days providing half of the electricity demand?
You know what’s coming.
There are no comparable data being collected for Scotland, of course, but an AI estimate is ‘well over 300 days!’
I asked what that means – ‘300–350+ days out of 365‘! The true number could be closer to 350 or higher in a good wind year like 2025 appeared to be, but without region-specific daily data publicly tabulated, this remains an informed estimate based on annual trends, quarterly output, and known variability.‘
A human comment – ‘nearly every bloody day!‘
Here’s a tougher question that the ONS would not ask of the UK as a whole:
On how many days in 2025, could all of Scotland’s electricity have come from renewables?
Despite repeated pokes from me, to its credit, it would not give a precise figure because of a lack of official figures.
However, see this:
Given 2025’s much higher total output (13% up on 2024, with record capacity additions) and persistent high curtailment signalling ongoing oversupply on windy periods, my best educated guess is that renewables could have fully supplied Scotland’s electricity demand on at least 200–250 days — well over half the year, concentrated in windier months.

Wind power supplied over half of Scotland’s needs …and that was without Damn Jaikie Baillie plugged in to the Grid !

No mention of battery storage?

“Renewable electricity pipeline
As of the end of September 2025, there were 1,174 renewable energy projects with an estimated capacity of 83.0 GW in the planning pipeline in Scotland. Of these there were:
The technology with the most estimated capacity in the pipeline is battery storage (31.0 GW), followed by onshore wind generation (18.2 GW) and offshore wind generation (17.8 GW; Figure 9).

It’s not so much “There are no comparable data being collected for Scotland…” rather than what is released into the public domain is tightly restricted.
You only need glance at the installed capacity to realise ” my best educated guess is that renewables could have fully supplied Scotland’s electricity demand on at least 200–250 days ” is a massive underestimate on 365….

I’m sure we’ll soon find out how much of it our southern neighbour’s belligerent government will be helping themselves to without making any payment won’t we.
what is wrong with the Scottish people that they accept this abuse?

It is ironic that the lazy image going with this article is AI generated. A energy consuming nonsense wether the energy is reneable or not..
