Big Freeze Threatens Texas With Blackouts as Markets Gyrate
[quote]The arctic freeze gripping the central U.S. is raising
the specter of power outages in Texas and ratcheting up pressure
on energy prices already trading at unprecedented levels.
In Texas, where temperatures in Dallas are forecast to be 3
degrees Fahrenheit Monday (minus 16 Celsius), the operator of
the state’s power grid warned it may need to resort to rolling
blackouts as surging demand for heat strains the electrical
system. While outages may occur Sunday, the risk is higher on
Monday and Tuesday, when officials expect power demand in Texas
to reach a record high.
“We could be in emergency operations as early as tonight,” said
Dan Woodfin, a senior director for the Electric Reliability
Council of Texas, which runs the grid. “We would expect to be in
emergency operations tomorrow through at least Tuesday morning.”
About 800 daily records for cold temperatures have been set in
the past week as Arctic air pushes all the way to the Gulf of
Mexico, sending gyrations through energy markets. Spot prices
for electricity in Texas are expected to hit the grid’s cap of
$9,000 per megawatt hour. Natural gas rose to a record $600 per
million British thermal units in Oklahoma. And as much as half a
million barrels a day of oil output in West Texas may be
impacted by well shutdowns that began on Thursday because of the
extreme cold.
“It is a pretty brutal air mass,” said Bob Oravec, senior branch
forecaster at the U.S. Weather Prediction Center. “The cold air
is entrenched across the middle part of the country. High
temperatures are amazingly cold, some 50 degrees below average.”
Through early Sunday, the coldest spot in the U.S. was 25 miles
east of Ely, Minnesota, where readings fell to -50 degrees
Fahrenheit. As of 7 a.m. New York time, 2,653 flights around the
U.S. through Monday had been canceled, the majority in Dallas
and Houston, according to FlightAware, an airline tracking
service.
Temperatures fell so far below forecasts in parts of the central
and western U.S. that physical gas prices soared from California
to the Rockies, with one hub in Cheyenne, Wyoming, reaching as
high as $350 per mmBtu, according to traders who asked not to be
identified because the information isn’t public.
Heating and power plant fuel traded for as much as $195 per
mmBtu in Southern California. If day-ahead electricity prices
are any indication and the weather forecasts are even partly
accurate, the run-up in energy prices isn’t over.
In Houston, there are long lines to refill household propane
canisters. Itinerant, roadside firewood are largely out of
supplies.
A mix of freezing temperatures and precipitation threatens to
paralyze wind farms in Texas. That would be devastating for
power plants with contracts to provide a certain amount of
electricity at specific times if they need to instead buy it on
the spot market to meet their obligations. At the moment, that
power is exceedingly expensive.
“When wind-turbine blades get covered with ice, they need to be
shut down,” said Joshua Rhodes, a research associate at The
University of Texas at Austin who focuses on energy.
About half of Texas’s wind turbines were inoperable Sunday
morning because of ice and cold. Yet those that are running are
cranking out more power than forecast for this time of year,
Woodfin, grid operator Ercot’s senior director, said during a
briefing Sunday.
Power plants that are only partially operating could be pinched
by high prices, too. Projects that commit to provide 50
megawatts of energy in a given hour but only produce 20
megawatts may need to buy the difference at the market price,
said Lee Taylor, chief executive officer of RESurety, a
clean-energy analytics firm.[/quote]

Sir David Attenborough UN Speech: 'It's Too Late to Avoid
Climate Change'
[quote]Sir David Attenborough addressed the United Nations
Security Council on Tuesday stressing the dangers of climate
change on global security.
Attenborough, who has narrated several documentaries on Earth
and its resources told the council that the world is "perilously
close" to temperature tipping points that will send global
temperatures spiraling "catastrophically higher."
"No matter what we do now, it's too late to avoid climate
change. And the poorest and most vulnerable, those with the
least security, are now certain to suffer."
Attenborough's appearance came as member states gathered to
discuss threats to international peace and security posed by
climate change and the relation between climate and conflict.
"Perhaps the most significant lesson brought by these last 12
months has been that we are no longer separate nations, each
best served by looking after its own needs and security,"
Attenborough added.[/quote]

[quote]The Dallas-Fort Worth area went from experiencing
sub-zero temperatures on February 16 to hitting temperatures
above 80°F just a week later. Other Texas cities like Wichita
Falls, Fort Worth, Waco, Abilene, and San Angelo have also seen
massive swings in temperature since the winter storm that left
millions of state residents without power for days, many of whom
are still without running water.
Texas certainly has its changes in weather from week to week.
But David Bonnette, a meteorologist for the Fort Worth National
Weather Service, told CNN, ‘Normally, we are used to
temperatures in the 60s, not a 60-degree temperature swing.’
There is widespread consensus among experts that the climate
crisis is contributing to uncharacteristic weather phenomena. As
the Arctic region continues to warm, the frigid, low-pressure
air in the polar vortex can be pushed further south into the
Northern Hemisphere, resulting in severe winter storms in areas
that typically do not experience them, like the recent one in
Texas.
As Judah Cohen, a forecasting director at the org Atmospheric
and Environmental Research, told the NY Times, ‘Severe winter
weather is much more frequent when the Arctic is warmest. It’s
not in spite of climate change, but related to climate
change.’[/quote]
