h/t Alba; Think about receiving a quarterly family electrical energy invoice of £10,000 – as a result of that is the form of cash Britain’s Electrical energy System Operator paid final Wednesday, to forestall blackouts through the heatwave.
London narrowly averted blackout as electrical energy costs surged final week
The UK was compelled to pay 5,000% increased than the everyday worth for electrical energy to forestall an influence blackout in south-east London.
Britain paid the very best worth on document for electrical energy in London final week because the capital narrowly averted an influence blackout, it has emerged.
Nationwide Grid’s Electrical energy System Operator (ESO) was compelled to pay £9,724.54 per megawatt hour to Belgium, greater than 5,000% increased than the everyday worth, final Wednesday to forestall a blackout in south-east London, as first reported by Bloomberg.
A sequence of points across the hottest UK days on document led to excessive constraints within the energy system and hiked up demand.
…
Whereas the quantity purchased on the document quantity was minimal – reportedly sufficient to produce eight homes for a yr – it has uncovered the UK’s reliance on importing electrical energy from interconnectors abroad, notably France, Belgium and the Netherlands.
…
However Wednesday’s sky-high transaction might be felt by households of their upcoming power payments as power suppliers go on the prices.

A part of the explanation for the electrical energy shortfall may need been the British photo voltaic panel fleet’s failure to carry out throughout sizzling climate.
Climate ‘too sizzling’ for photo voltaic panels
Energy output throughout heatwave drops beneath ranges sometimes reached in spring
By Helen Cahill
19 July 2022 • 7:07pmThe climate was too sizzling for photo voltaic panels on Tuesday as hovering temperatures lowered their effectivity.
Because the heatwave pushed the mercury above 40C for the primary time ever in Britain, photo voltaic output remained properly beneath the degrees often reached at peak instances in spring.
…
Photo voltaic panels develop into much less environment friendly when temperatures rise above 25C, that means power technology drops off, with effectivity lowering by round 0.35 share factors for each diploma above this degree.
Professor Alastair Buckley, of the College of Sheffield, mentioned: “We by no means see peak output in mid summer season.
“The temperature of the particular photo voltaic cell will depend on a mixture of the ambient temperature and the radiative heating from the solar and likewise cooling from wind. We noticed cell temperatures of 70 levels yesterday on our check system. Usually it might be between 40 levels and 50 levels.”

Are you able to think about a worldwide warming power resolution extra ineffective, than an answer which fails in sizzling climate?
This battle to produce ample power throughout opposed situations makes me marvel what Britain’s subsequent winter can be like. Photo voltaic is near ineffective throughout winter at excessive latitudes, and widespread extended European wind droughts like final September usually are not precisely unusual. If Russia continues to play geopolitical video games with gasoline provides, and France continues to expertise issues with their nuclear fleet, there could also be no spare capability obtainable at any worth, subsequent time Britain run in need of electrical energy.
Solely British voters can repair this disaster, by demanding politicians prioritise power safety and affordability over hitting web zero targets.
