UK Grid Warns Of Electricity Shortage Due To Drop In Wind

UK Grid Warns Of Electricity Shortage Due To Drop In Wind

The UK’s electricity grid operator has warned of a short supply over the next few days due to generator outages and a lull in autumn winds.

The National Grid said on Oct. 14 that it was exploring various measures to create a buffer to avoid potential outages, like the one last summer that left 1 million homes without power.

“We’re forecasting tight margins on the electricity system over the next few days owing to a number of factors including weather, import and export levels and availability of generators over periods of the day with higher demand,” the National Grid said in a statement.

“Unusually low wind output coinciding with a number of generator outages means the cushion of spare capacity we operate the system with has been reduced.”

Power outages in the UK are rare. The last blackout was over a year ago and lasted for only one hour.

In an update on Oct. 15, the National Grid said that margins are currently “adequate” and it will continue to monitor the situation through the weekend.

According to the National Grid, last month one-fifth of the power supply came from wind, “in spite of unusually calm British weather during the middle of September.”

The latest announcement may fan concerns about over-reliance on wind power, which critics say is unreliable compared to gas or nuclear power.

Growth in Renewable Energy

Renewable energy has been a rapidly growing source of electricity in the UK. According to government data, 47 percent of UK electricity generation came from renewables in the first quarter of 2020, compared to 36 percent from the same time in the previous year.

Hurricane-Force Winds Fan SoCal Wildfires As 200,000 Residents Flee Their Homes

Hurricane-Force Winds Fan SoCal Wildfires As 200,000 Residents Flee Their Homes 

At least four devastating wildfires continued to ravage Southern California from Ventura County south to Los Angeles, as the stifling smoke and flames drove tens of thousands of people living in the Los Angeles area from their homes in an eerie replay of the fires that decimated Northern California’s wine country two months ago.

Officials in Southern California have warned that powerful winds (as high as 80 mph in some spots, the same speed as a low-level hurricane) would continue to fan the flames after returning overnight. So far, more than 200,000 people have evacuated their homes and many more are expected to flee. The Los Angeles Fire Department has ordered the evacuation of the 20.5 square miles including and surrounding the Creek Fire, which jumped the 210 Freeway and is threatening Santa Ana’s Sylmar and Lake View Terrace neighborhoods. The Rye Fire in Santa Clarita prompted the shutdown of Highway 5, according to Mashable.

“We are in the beginning of a protracted wind event,” said state fire chief Ken Pimlott.

“There will be no ability to fight fire in these kinds of winds,” Pimlott said. “At the end of the day, we need everyone in the public to listen and pay attention. This is not ‘watch the news and go about your day.’ This is pay attention minute-by-minute … keep your head on a swivel.”

According to the Los Angeles Times, communities both on the coast and inland were under threat. At 4 a.m., officials closed the 101 Freeway between Routes 126 and 150. According to the California Highway Patrol, that left no open routes between Santa Barbara and Ventura counties. Fires were also burning on the north and east side of Highway 150 and on the west side of Highway 33.

Meet “Stunningly Catastrophic” Patricia, The World’s Strongest Storm Ever Is About To Hit Mexico

October 23, 2015

Meet “Stunningly Catastrophic” Patricia, The World’s Strongest Storm Ever Is About To Hit Mexico

“Stunning, historic, mind-boggling, and catastrophic” is how Weather Underground’s Jeff Masters sums up Hurricane Patricia, which intensified to an incredible-strength Category 5 storm with 200 mph winds overnight as it approaches the Mexican coast. As The NY Times reports, The World Meteorological Organization warned that the hurricane’s strength was comparable to that of Typhoon Haiyan, which caused devastation in the Philippines in 2013, and so Mexico has declared a state of emergency for Puerto Vallarta (with officials warning that storm surges could cause waves of up to 39 feet) as she is forecast to hit the coast between 6 and 10pm ET.

As Weather Undergound reports,

At 2:46 am EDT October 23, 2015 an Air Force hurricane hunter aircraft measured a central pressure of 880 mb in Patricia, making it the most intense hurricane ever observed in the Western Hemisphere. The aircraft measured surface winds of 200 mph, which are the highest reliably-measured surface winds on record for a tropical cyclone, anywhere on the Earth.The previous strongest Eastern Pacific hurricane was Hurricane Linda of 1997, with a pressure of 902 mb (estimated from satellite imagery.)

Patricia the fastest-intensifying Western Hemisphere hurricane on record

Patricia’s central pressure dropped an astonishing 100 mb in 24 hours, making it the fastest-intensifying hurricane ever observed in the Western Hemisphere. Patricia’s pressure at 5 am EDT Thursday, October 22, 2015 was 980 mb, and was 880 mb at 5 am EDT Friday. The previous record was a drop of 97 mb in 24 hours for Hurricane Wilma of 2005 (between 1200 UTC 18 October – 1200 UTC 19 October), according to the official NHC report for the storm.

Patricia’s intensification rate was very close to the WMO-recognized world record for fasting-intensifying tropical cyclone: 100 millibars in just under 24 hours by Super Typhoon Forrest in the Northwest Pacific in 1983.

Patricia’s 200 mph sustained winds make it the 3rd strongest tropical cyclone in world history (by 1-minute averaged wind speed.)
