Is this really the main problem? On a windless or low-wind winter evening shortly after dark, little output can be expected from wind – and none from solar – sources. This is where the power cuts seem most likely to happen due to demand exceeding supply, if too much ‘traditional’ power generation (coal, gas, nuclear) is closed down in favour of so-called renewables, which may need renewing every 15-20 years or so. Blind pursuit of misguided climate-related ideologies ignores, or tries to play down, these issues.
Ministers should impose limits on the construction of new wind and solar farms to help avoid a nationwide blackout, according to a former director of National Grid.
Colin Gibson, who was power network director of Britain’s electricity system, claimed that some existing turbines and solar panels may have to be disconnected, and new developments restricted, to “secure” the system after major power cuts earlier this month.
In an analysis co-written by Dr Capell Aris, a former grid engineer, Mr Gibson states that the system failure revealed several “serious problems” with the operation of the national electricity network, which require an “immediate, independent, expert review”.
Their intervention comes amid a government inquiry into the outage, which occurred after the Little Barford gas-fired power station in Cambridgeshire and a major wind farm off the Yorkshire coast both temporarily stopped producing electricity.
According to the Financial Times, a provisional report by National Grid suggested that the wind farm may have tripped offline seconds before the Little Barford power station.
The blackout affected a million people in London and the South East, the Midlands, the South West, Yorkshire, the North East, Cornwall and Wales.
National Grid, the firm that operates the country’s power network, has insisted that unpredictable wind power generation was not to blame.

Virtual power plant market to be worth $4.5bn by 2024 says report
08/16/2019
Rising demand for electricity generation from renewable energy sources and low grid strength drive the growth of the virtual power plant market.

A Virtual Power Plant is a network of decentralized, medium-scale power generating units such as wind farms, solar parks, and Combined Heat and Power (CHP) units, as well as flexible power consumers and storage systems. The interconnected units are dispatched through the central control room of the Virtual Power Plant but nonetheless remain independent in their operation and ownership.
The objective of a Virtual Power Plant is to relieve the load on the grid by smartly distributing the power generated by the individual units during periods of peak load. Additionally, the combined power generation and power consumption of the networked units in the Virtual Power Plant is traded on the energy exchange.

BLACKOUT FEARS OVER NATIONAL GRID CABLES FROM EUROPE
Date: 19/08/19 The Times
Britain’s National Grid is routinely restricting the use of its own power cables from the Continent because of the risk of blackouts if they failed.
Britain’s electricity system is sufficiently fragile at certain times of day that if one of the subsea “interconnectors” tripped while importing at full capacity, it could trigger power cuts like those of August 9.

Perhaps we can add drone attacks to the list of risks following the incident at Didcot. Shorting out between different phases can produce some high voltage sparks, with the drone acting as the pathway. Do that on key transmission lines and you can generate cascading trips that will bring the whole system to its knees. The loss of a single transmission line (e.g. when a light aircraft crashes into it) is a contingency that the system can handle. A carefully coordinated attack might be a different thing altogether.
It would be much better if the government repealed the Climate Change Act 2008, removed all subsidies for unreliable renewable energy and remove the requirement that renewable has first preference when available, then make it a requirement that base load power has to be supplied from reliable sources (coal, nuclear). That should stabilise the grid and get realistic power prices back.
Coal has nearly gone from the UK electricity grid system, and what’s left is last in the pecking order so to speak.
‘Ministers should impose’
Ministers have done enough imposing already. When their autocratic meddling goes bad, they propose MORE meddling.
What would be the optimal limitation on wind and solar to gain maximum benefit to the grid?
How about a number as close to 0 as possible…

UK power cut: Ofgem launches probe into mass blackout after National Grid finds outage was caused by lightning strike
The interim report said: “Two almost simultaneous unexpected power losses at Hornsea and Little Barford occurred independently of one another – but each (was) associated with the lightning strike.
“As generation would not be expected to trip off or de-load in response to a lightning strike, this appears to represent an extremely rare and unexpected event.”

Hornsea went off first according to a TV report, but BBC shows a graphic with Barford going off first, 2 minutes before Hornsea. This can’t be right as the same lightning strike is supposed to have caused both outages.
We have the interim report

Looks like my amateur sleuthing was pretty much spot on.
I even finally got the BBC to amend their diagram showing the Hornsea outage at 17:00 to show 16:52 – just 9 days after I first complained to them about it.

Good one. That’s probably quite quick for the BBC, but they can’t argue with the official report 😎
How long before the BBC and all the rest claim that man-made global warming is making lightning strikes worse? Or are we feeding them ideas 😆
