Lawyers to investigate claims of GB power grid cover-up over blackout risk
Operator brings in independent legal firm to look into whistleblower allegations relating to June heatwave
Jillian Ambrose Energy correspondent
Quote: Industry data shows that power grid frequency fell below operational limits as the high-pressure heat dome curbed renewable energy generation and triggered unplanned outages at gas plants, while demand for electricity to run air-conditioning systems surged.
The whistleblower alleged that during this period senior bosses ordered control room staff to ensure that there was no audit trail or records of key decisions made relating to managing fluctuations in the electricity system.
In a letter to the UK’s data watchdog, Coutinho said that a whistleblower had alleged that staff were told not to keep permanent records of their decisions and that Neso’s corporate affairs team attempted to pressure operators to make decisions in order to protect the organisation’s reputation.

Somewhat similar to the belatedly emerging story this week of alledged fraud by Southern Water top execs

The normal claptrap from Spike the right wing stirrer. subsequent reports in the press explain that it simply is not possible to conceal decisions made by NESO over which generating assets are switched on and off, and the fluctuations in grid frequency again impossible to conceal, not 'industry data' and never fell outside statutory limits.
But Spike just posts any old junk that he thinks supports the Farage agenda, because he loves him.

You should have seen the s**te he, spike aka Burton Bradstock, posted to uk.radio.amateur.

ROFL!! The ‘right wing stirrer’ quoting an article from The Guardian! You couldn’t make it up. But that’s a Marxist-style tactic for you, sling mud hoping some will stick.
Next on the list…anyone’s guess.

For a lot of people, anything they have to find out themselves is evidence of a deep state conspiracy. Althougn I have read that it's also a good way to smoke out people who have the wherewithal to do their own research to be kept an eye on ....

I don't think that's the main reason.
The Telegraph quite likes these grid-doom stories.
Grid loads are quite interesting - I'm witnessing it first hand as I've a variable supply/demand tariff. Today, and weekends in general this summer, electricity is pretty much free, varying between 1p and 5p when I've bothered to look. And it's costing me 1p per kWh to if I'm folish enough to export.
They'll get me in the end - gas on this tariff is about 10% more expensive, and once the solar drops off I have a feeling the winter months will be pricey.

Perhaps they know something you don't?
Grid loads are no longer determined by what people use, but by what they randomly generate.
Every rooftop solar installation is a penny on someone elses bill. Every wind farm is a quid.

“By 6.52pm, the frequency of Britain’s grid had sagged below the normal operating threshold of 49.8Hz.
It hit 49.685Hz at 7pm, according to market data from Elexon, and then stayed outside the comfort zone for most of the next 30 minutes.”

Genuinely didn't know that.
Assumed daylight and night variations, and the weekend drop-off in prices, was a demand-led thing. And every day it dumps my battery on to the grid between about 5 and 7pm - when electricity is most expensive.
That's a neat graph. I take it that there wasn't a problem as such? The frequency did operate outside of where the operator would ideally like them to be, but well within statutory limits?
The story seems to be not that there was a problem with the supply, but that a Tory MP has raised concerns about supressed staff whistleblowing. Fair enough I suppose.

I wondered what frequency caused the electric trains to trip-out in August 2019, unfortunately that website didn't start until September
2019, but the Office of Rail and Road report says it happened at 49.0Hz

Please. It's "Der Telegraff" now.
Articles now must reflect the views of Mathias Döpfner (or at the least, not conflict with them).

The inquiry is being set in motion by the conservatives.

No. The story is that there was a real issue with the supply but NESO staff were told to erase any information about it.
Conservative shadow energy secretary Claire Coutinho is leading an inquiry into the National Energy System Operator (NESO) regarding whistle-blower allegations of hidden grid instability, manipulated record-keeping to bypass Freedom of Information laws, and corporate interference in control room decisions during the late June 2026 heatwave. Whistle-blower Claims and Timeline
June 23, 2026: Grid frequency allegedly dropped below normal limits during high temperatures, which whistle-blowers claim risked blackouts.
July 7, 2026: Claire Coutinho wrote to the Information Commissioner and energy regulator Ofgem alleging that NESO managers instructed staff to avoid leaving paper trails on operational decisions.
Mid-July 2026: NESO appointed external law firm Eversheds to investigate, though Coutinho dismissed this internal probe as a "sham" because its terms exclude core grid security questions.
Government and Regulator Response =======================
Ofgem Involvement: The energy regulator is monitoring the independent legal findings and launching its own parallel oversight into grid operations during the June heatwave.
NESO Stance: NESO maintains that the electricity grid remained stable, no customers lost power, and operational decisions are made exclusively by authorized control room personnel.
Coutinho brands NESO whistleblower inquiry a 'sham'

======================
Points to note.
Neither Nigel Farage or Reform are in any way involved and suggesting that they are is pure idiocy and political posturing
The issues is that "allegations of hidden grid instability, manipulated record-keeping to bypass Freedom of Information laws, and corporate interference in control room decisions during the late June 2026 heatwave." were made.
Essentially to hide the gravity of the situation from scrutiny.
Now you all have the facts how about considering them without mudslinging

That seems a reasonable attitude. We delegate responsibility to run the grid safely to experts. I, like almost everyone else, don't understand enough to quantify specific risks, but I would expect experts to make clear to us in general terms that such risks exist, and the cost of mitigating them. So if significant risk are concealed it is natural to assume deep state conspiracy. The deep state obviously does conspire against the interests of the common man.
I don't know the magnitude of risk in this case, but Spain's grid did go down. I suspect it is one of the more easily solved energy problems facing us. A mere teething problem of new technology, as opposed to the very deep energy related problems we are currently facing.
Just noticing bad stuff isn't a problem, most people are ineffectual and can be ignored. It is only genuine influencers that are a problem.

Luckily, this time the fleet of SouthWest Trains did not come to an irrecoverable halt, like they did when Hornsea tripped out :-)

So you say. That article suggests that the supply was within government defined limits. Unless you know otherwise?
Eh?
What 'gravity'? I suppose the truth will out following the inquiry.
Who was I slinging mud at?
