BRITAIN’S BLACKOUT WAS CAUSED BY AN OUTAGE AT A WIND FARM: National Grid Failure Report Points To Wind Farms.

National Grid’s preliminary investigation into the blackout that caused widespread disruption in England and Wales last week has raised the possibility that it was caused by the world’s largest offshore wind farm accidentally going offline.

The provisional report, which was submitted to regulators on Friday, suggests for the first time that the Hornsea offshore wind farm, which is owned and run by Denmark’s Orsted, may have tripped offline seconds before an outage at a smaller, gas-fired station.

The findings, which were relayed to the Financial Times by people briefed on the report, suggest the blackout may have been avoided if not for an error at the wind farm.

Investigators had originally thought the shutdown of the Little Barford gas-fired plant in St Neots, west of Cambridge, had triggered a domino effect across the network that led to the blackout.

Investigators now suspect the problems on the grid started when lightning hit part of the network near Cambridge. This caused 300MW-400MW of capacity in the local electricity network, which normally means small-scale renewable power, to go offline. Such a small outage should not have caused any problem for the wider grid. Lightning strikes are common on National Grid infrastructure, which is hit on average three times per day, and they rarely cause serious problems.

But the strike coincided with the almost instantaneous total loss of supply from the Hornsea wind farm, which lies off the coast of Yorkshire. The facility, which is still under construction, was generating as much as 800MW for the grid last Friday afternoon before cutting to 0MW in less than a second.

Hmm.

DISPATCHES FROM THE EDUCATION APOCALYPSE: “Public schools are reopening for business across America, meaning it’s time to get  back to reading, writing, arithmetic….and revolution. As usual in matters such as these, California is leading the way. On the first day of classes at Denair Middle School near Modesto science teacher Luis Davila Alvarado handed out worksheets from a transgender advocacy group titled ‘The Gender Unicorn’ asking students about their ‘gender identity,’ ‘gender expression,’ and their sexual and emotional attractions. These are children. And yet the teacher did not ask permission to hand this out. Most parents were outraged. The school estimated about 50 children received the worksheet. It turns out Alvarado was educating the children about his own life. He declared he rejects the term ‘Mr.’ and prefers to be addressed with the newfangled ‘Mx.,’ pronounced ‘Mix.’ A school official quickly put a stop to it, but the damage was done.”

CNN’S WEEK FROM HELL CONTINUES: Now There’s an Eyewitness to Don Lemon’s Alleged Assault. “What say you, libs? Anything to add, #TimesUp? Either we view unwanted sexual advances as a serious problem or we don’t. Is there a particular reason Don Lemon should be exempt? Don’t the rules apply to him as well?”
