    Texas weather: Are frozen wind turbines to blame for power cuts?

    Critics of green energy in the United States have blamed the failure of wind turbines for the power shortages in Texas during the recent freezing conditions there. The power grid was clearly overwhelmed, but to what extent was a loss of wind power to blame?

    Was wind-power failure the problem?

    Texas has promoted the development of wind energy over the past 15 years, and some of these turbines certainly froze in the recent bitingly cold conditions

    But so did vital equipment at gas wells and in the nuclear industry.

    And these failures in the non-renewable energy sector had a much greater impact.

    Breaking down the numbers

    On average, renewable energy sources - mostly wind - account for about 20% of the state's electricity supply.

    At the height of the freeze last week the state's principal energy supplier, the Electricity Reliability Council of Texas (ERCOT), said the freezing conditions had led to:

    • 30GW being taken offline from gas, coal and nuclear sources
    • a 16GW loss in capacity in wind and other renewable energy supplies
    And this, it said, had severely curtailed its ability to satisfy a peak demand of 69GW - a surge even greater than anticipated.

    The company's Dan Woodfin said: "It appears that a lot of the generation that has gone offline today has been primarily due to issues on the natural gas system."

    Why weren't the turbines self-defrosting?

    Turbines can be equipped to deal with freezing temperatures.

    "The wind energy industry has almost five decades of experience designing wind turbines to operate in freezing temperatures in harsh climates," says Prof Benjamin K. Sovacool at the University of Sussex.

    Turbine blades can be heated, special anti-freeze fluids used, along with better insulation of gearboxes.


    The blades themselves can also designed for performance in sub-zero temperatures.

    But this only makes economic sense in places that regularly experience extreme conditions, such as in Alaska, Canada and northern Europe.

    "Operators [in Texas] didn't invest in the usual weatherization or ice protection techniques says Prof Sovacool "because generally they didn't expect it to become so cold,"

    ERCOT calls for rotating outages as extreme winter weather forces generating units offline


    Almost 10,000 MW of generation lost due to sub-freezing conditions

    AUSTIN, TX, Feb. 15, 2021 – The Electric Reliability Council of Texas (ERCOT) entered emergency conditions and initiated rotating outages at 1:25 a.m. today.

    About 10,500 MW of customer load was shed at the highest point. This is enough power to serve approximately two million homes.

    Extreme weather conditions caused many generating units – across fuel types – to trip offline and become unavailable.

    There is now over 30,000 MW of generation forced off the system.

    "Every grid operator and every electric company is fighting to restore power right now," said ERCOT President and CEO Bill Magness.

    Rotating outages will likely last throughout the morning and could be initiated until this weather emergency ends.

    Except CBS was saying the same thing as the BBC did. So not left wing and not kooky, just factual.

    Throughout this crisis, it's only been the right wing manipulating and out right falsifying data.

    Get it?

    I just proved you wrong, using your own link. Nice spin there. You must be getting dizzy.

    The problem as I see it, is that you and several, if not most of the posters in this forum, are so far to the right that it's not hard to post from a site to the left.
