From BBC Scotland today:
Wind farm agreements have been announced for three new developments in the waters around Shetland. The projects, covering an area of just over 560km2, are expected to generate a total of 2.8 gigawatts per hour of electricity.https://www.bbc.co.uk/news/uk-scotland-north-east-orkney-shetland-62632865
This isn’t actually a huge increase in Scotland’s electricity production of 27.2 terrawatts per hour. A gigawatt is only a billion watts. A terrawatt per hour is one trillion watts.
Between Quarter 1 2021 and 2022, net electricity transfers from Scotland to England rose by 12 per cent to 5.9 TWh, as weather conditions were particularly favourable for Scottish renewables.Imports, exports and transfers of electricity – GOV.UK
1 gigawatt per hour will power around 750 thousand homes (source below) so a terrawatt per hour will do 7 .5 million homes.
Scotland generated 27.2 terrawatts per hour of renewable electricity in 2021 (source below) so could power 204 million homes. There are around 28 million households in the UK so around 3 million in Scotland (source below). So 28 million homes and enough electricity to also power all the other buildings too?
16 TWh was exported (beyond the UK). 1 Terrawat per hour, in 2022, is worth around $190 billion. Does that make it into the GERS data?
