    Something like that. I seem to recall their peak being <1GW. But that's the advantage of SPP, it aggregates all the utilities into a large regional operator so when it's windy in OK SPS can buy wind. If it's windy in NM they can sell it.

    In the rate case Xcel said they expected a CF of ~52% for the wind farms IIRC.

    EIA Electricity Power Monthly - December 2020 for October 2020.

    Wind generation for October 2020 increased compared to October 2019, with 29.4TWh compared to 28.1TWh.

    In rolling 12 month generation, wind power is at 323.1TWh and 7.97% of generation, up from 289.7TWh and 6.94% a year ago.

    322.2MW of new capacity was added in October 2020. Planned new capacity for the next 12 months, decreased by 727.4MW, lowering the planned 12 month total to 19,087.6MW, which would increase total capacity by 17.42%.

    Included estimated solar, solar plus wind has reached 11.11% of generation.

    Somewhat related to wind generation, we went for a drive yesterday afternoon (12/23). We finally had a sunny day, my wife is on vacation and wanted to go for a drive to enjoy the sun. I took the afternoon off to join her.

    I think the picture was taken approximately at 45.10549854573665, -69.71467718702205. It's part of the Bingham Wind Farm. The turbines are 492 feet to the top of the blade, just under the 500 feet at which projects require FAA approval.

    (Somewhere further west on ME-16, as you begin to descend, the view briefly opens up and provide a great view of the hills to the west. Probably not quite so good when the leaves come back onto any deciduous trees in the mix there. The foliage has a tendency to get in the way of the views here.)

    EIA Electricity Power Monthly - January 2021 for November 2020.

    Wind generation for November 2020 increased significantly compared to November 2019, with 33.8TWh compared to 25.7TWh. That is a new record for wind generation in a single month, even though November isn't normally especially windy.

    In rolling 12 month generation, wind power is at 331.9TWh and 8.21% of generation, up from 292.7TWh and 7.03% a year ago.

    1,425.8MW of new capacity was added in November 2020. Planned new capacity for the next 12 months, increased by 666.5MW, increasing the planned 12 month total to 18,328.3MW, which would increase total capacity by 16.52%.

    Included estimated solar, solar plus wind has reached 11.42% of generation.

    AB525: Offshore Wind Generation
    Develop a strategic plan by 6-1-22 to implement:
    3GW by 2030
    10GW by 2040

    Bill Text - AB-525 Energy: offshore wind generation.

    @ItsNotAboutTheMoney shows about 100,000MW total installed wind in the U.S. The 10,000MW in AB525 would add about 10% to that number. Currently, the Diablo Canyon nuclear reactor generates 2,256MW, so say 4x more than the reactor that will be shutting down. Diablo produces about 10% of in-state electricity. So AB525 would essentially end up replacing the lost 10% of nuclear with 40% off-shore wind.

    I have a long time friend that lives in Texas and he continually sends me information about why wind energy is bad. I finally pointed out to him that Texas has more wind generation than any other states and a year ago ranked fifth in the world.

    Bad how? Uneconomic or killing birds or?

    A bit of nitpicking --
    Off-shore wind has ~ 1/3 more capacity than on-shore
    Nuclear has ~ 2x the capacity of off-shore

    So the off-shore proposal is ~ 2x Diablo

    --
    By the way, I listened in on a state planning commission this week and was told that NM thinks they can build 6 GW of lines to CA by the end of the decade. Not bad ... until you realize that NM has 450* GW of exploitable wind resources. What can I say ... anything less than development of 10% of the state resource this decade is pathetic

    *Four hundred and fifty Gigawatts

    We really need Federal help. Everything I've heard about building transmission infrastructure is that it's a compete nightmare of easements and dozens of jurisdictions. It's like building a pipeline without the profit motive. They've been trying to build a 30GW HVDC 'superstation' in NM for >10 years and haven't even broken ground yet...

    The ones about wind farms are mostly about killing birds. One was from an organizations that gets their funding from some pipeline owners and it stated that the reason for high energy costs was due to the high cost of renewables. I just got another one from him about how Lithium and Cobalt mining are bad. I asked him if he is going to give up his smart phone. I think the fossil fuel industry is getting desperate when they have to use environmental arguments instead of economic arguments.

    I remind my friend in Texas that I will visit him when I pick up my Cybertruck at the factory in Austin.

    Not so much in the case of NM. The ROW already exists.

    The NM RETA people are trying to appease the locals so they are planning for AC (which can be tapped into locally) rather than DC.
    The RETA folk are short sighted. The state is vastly better off with deep development instead of local pilfering.

    Normally, when talking about wind energy installations, the GW is expressed in nameplate capacity. In other words, when the wind is blowing at optimal speeds, and the wind turbine is neither curtailed nor impaired by, e.g., icing.

    Because wind is intermittent, what you end up having to do to get an _approximation_ of the wind turbine's output, is you have to apply a capacity factor, that is consistent with the prevailing winds in the area. In the windswept plains of the the middle of the U.S., a typical capacity factor is around 42%. Much of the remainder, and in particular, the coasts, is closer to 35%. So, the 2040 numbers, for example, are more realistically:

    10,000 MW x .35 = 3,500 MW

    some use of stationary batteries and demand response can maybe smooth out the peaks and the valleys. However, overall, off-shore proposal, is closer to 165% of Diablo.

    I noticed that our NM wind power is also way down the last couple of days, perhaps for the same reason.
    I presume that wind turbines in Scandinavia have mitigations, that have not been adapted in the USA SW due to the infrequency of occurrences.

    I assume it's blade icing? Like airplane wing icing? I must admit I'd never considered that problem.

    There are different mitigations:
    - phobic coatings
    - blade heaters
    - spray as needed from the air (similar to airplanes)
    Developers will obviously use whichever is the most profitable.

    on monday this was wind production, near zero... it isn't uncommon when it is windy to see greater then 20Gw, but not on this day. i believe we have over 25Gw of wind installed in Texas.
    this cold snap was long and cold, lakes and ponds froze, i had over 255 hours below 32, and right now i'm finally above freezing. even if NG plants were not having problems, we were out of NG as well had been tapped at to high of a rate for to long. wells start reducing production as they get too cold to produce gas (NG liquid expanding to gas is a endothermic process).

    Ercot wind production graph...

    If I'm doing the math correctly... Starship will carry enough CH4 to power a 1GW gas plant for nearly 24 hours. So clearly it's possible to store CH4. Seems like Gas plants need to have more of a buffer. What does that have to do with wind?
