Nom,
That's twice in two years that there have been large outages across the Texas grid due to cold weather. Frozen wind turbines was a high contributor on both occasions, as the Texas Regulators declined to specify de-icing equipment be fitted to save money.
It takes much longer than you'd expect to bring capacity back online, as once the power goes down, those parts of gas supply network that are winterised are frozen, creating a cascade effect. The gas plants themselves need electrical power to get back up and running and essentially they have to wait for gas plants that have been mothballed for Winter (Texas uses more power in Summer - A/C requirements), but they take a couple of weeks to bring back online.
Unlike in the UK, ERCOT also doesn't operate fixed term contracts for domestic consumers, so in the previous outage some home owners who still had power were finding their WEEKLY bill was in the thousands of $. Unsurprisingly, there was a big increase in homes being fitted with standby diesel generators.
The European Supergrid is in reality still only a thought exercise and essentially no progress has been made since it was first proposed over a decade ago. The UK leaving the EU is irrelevant, as the interconnectors are commissioned and powered by agreements between the power suppliers, not the EU.
Macron found this out the hard way when he threatened to cut the interconnectors between the UK and France...
Actually, when the EU Commissioners got involved in the European wide framework agreement for interconnector pricing, it was them (against the advice of Norway and the UK) who insisted on gas power being used as the reference price - as they thought they'd always have access to cheap Russian gas....
In the meantime, we currently have 9 interconnectors between the UK and Europe, capable of transmitting up to 9.8 GWhr to and from Europe, with at least one more being considered. The latest (the Viking link) is currently capacity limited by the Danish Grid, not the UK Grid.
BP is also correct, until the lack of grid scale storage (across Europe, not just the UK) is addressed, the electrical gird is vulnerable to interruptions during periods of low renewables generation.
Indeed, Denmark had to go to Court to order Orsted to re-open three Coal & oil fired power stations, while quietly shelving plans to expand offshore wind farms. Despite making a big announcement that they'd stop producing oil by 2035, they quietly dropped that commitment and opened up another offshore licencing round last year.
Similarly, Germany has reactivated mothballed Lignite power stations - the worst fossil fuel there is.
BTW, did you see that Norway announced the award of 62 Exploration Licences last week? Despite Norway already producing much more Gas & Oil than it consumes, there was no outrage in the media or wailing and gnashing of teeth from the Twitterati.
It seems that pointless virtue signalling is only for the UK..
