US Approves Massive Windfarm Project Off the Coast of Virginia (apnews.com) 72

Tuesday Orsted cancelled two wind farms near New Jersey that would've generated about 2.2 gigawatts of energy. But the same day America's Interior Department approved plans to install up to 176 wind turbines off the coast of Virginia with an estimated capacity of about 2.6 gigawatts of clean energy.

Located approximately 27 miles from the shores of Virginia Beach, the project will be America's largest offshore wind project, capable of powering over 900,000 homes. In just its first 10 years it should save customers $3 billion in fuel costs, Dominion Energy told the Associated Press: Dominion expects construction to be completed by late 2026... Construction of the project in Virginia is expected to support about 900 jobs each year and then an estimated 1,100 annual jobs during operations, the Interior Department said. The initiative has gained wide support from Virginia policymakers and political leaders, including Republican Gov. Glenn Youngkin, who last week attended a reception marking the arrival of eight monopile foundations for the windfarm.
Two pilot turbines have already been in place since 2020, the article points out. And when finished the new wind farm "would bolster and eventually replace the mostly natural gas-powered electricity that is contributing to costly climate change," reports MarketWatch President Biden, early in his first term, announced a goal of installing 30 gigawatts of offshore wind power by 2030, enough to power 10 million homes and prevent the spewing of 78 million metric tons of carbon-dioxide emissions... U.S. offshore wind has been helped along by nearly $8 billion in investments since Biden signed his signature, climate-heavy Inflation Reduction Act a little over a year ago... Biden's team has projected that the U.S. could install 110 gigawatts of offshore wind power by 2050, a major jump considering there is less than 1 gigawatt installed today. Land-based wind farms across the U.S. already produce more than 140 gigawatts of energy, contributing to about 10% of the nation's energy portfolio...

When measured by announced plans and pledges, the country has been barreling toward its offshore goal. To date, the Department of the Interior has approved four New England-based projects that, together with the new Coastal Virginia Offshore Wind project, promise to deliver 5 gigawatts of electricity, enough to power 1.75 million homes with average power use. A total of more than 51 gigawatts of wind power capacity is in the works off U.S. shores and the most ambitious 10 coastal states have combined offshore wind goals of generating more than 81 gigawatts.

    ITYM 140 gigawatts max in theory if they all have enough wind blowing past them.

    Wind power is a great idea but you have to be realistic - the wind doesn't always blow hard enough and when you get summer blocking highs which can last for days or weeks the turbines will produce nothing so there needs to be a plan B. Maybe solar+batteries partly but you also need a non renewable source such as nuclear or gas turbine.

      That's why you build them in places with near constant wind, and also build them out in a geographically distributed way. These people are smart, you know.

      The nameplate capacity of a generator is very rarely ever realized, no matter what the energy source is. Wind isn't radically different than hydro, solar, nuclear, or whatever else in that respect.

        Wind and solar are very different from other sources. The max you're going to get is whatever nature is offering up that moment, with nuclear, fossil fuels

        • Yes, ships can get becalmed but it is incredibly unlikely on a continental scale. Multiple power generation options will be required because no one option is going to generate enough long term at a cost we want except maybe coal which isn't an option due to its CO2 emissions.
        • "You never heard of sailing ships being becalmed for days in the past?"

          Yes, it happened, but it was rather rare. Remembered chiefly because it was rare, and calamitous when it did happen. A huge shipping industry was built around thousands of ships moving cargo and passengers. Why? Because the winds blew and the ships got where they were going to.

          Yes, we have heard. And that is at completely different places.
          There are places where the wind never stops and there are places were over a course of a year the wind ALWAYS stops for 4 to 6 weeks, at a specific time in the year.

          You could read that up. And also fix your high pressure zone myth on that way.

        Actually Wind and Solar are very different from many others in that regard, especially nuclear power. I mean this should come as no surprise to you since for sources of constant energy (water movement, steam temperature and pressure) you can select equipment to optimise generation, and the optimisation in that regard includes sizing equipment to try and achieve maximum efficiency at the known operating point. Wind and Solar on the other hand are optimised to maximise total generation across a wide range of

        • > Capacity factors for wind vary from 20-60% of the nameplate rating. If you designed a nuclear, coal, gas, or hydro installation like that you will be fired from your job.

          The capacity factor of coal and natural gas are both near 50%, with coal slightly below and gas slightly above.

          Capacity factor calculation includes time, not just the ratio of nameplate to actual output. If you run a coal plant at 100% nameplate output but only for 6 months, that's a 50% capacity factor for the year.

          • Very disingenuine comment. Fossil nameplates produce when told to. Renewables produce when nature wants. TX has quite a lot of wind, I think around 30GW nameplate. And as someone noted above, sometimes the wind she don't blow. Specific times I've seen problems is after a cold front comes thru in winter, the very time you need the most capacity is the night after the cold front, generally coldest night as skies are clear. Wind can drop to 5-10% of nameplate, just when you need it most. TX has ramped up Nat G

          Half the time it pumps uphill. The other half it lets water flow downhill. And now adjust to: it is actually idle and does nothing.

          River Flow water hydro plants depend on water hight. So most certainly not close to 100%.

          Hydro Dams also depend on water height, and on for what else the water is used, irrigation, level control on the river/creek below etc. So: also not 100%.

      That's what offshore excels at. The wind never stops out there, it just varies. And you have a massive area to distribute the windmills over.

          Having worked on the North Sea for many years and also knowing the US I can say the US offshore has a better chance of avoiding too little wind everywhere.
          Some Europeans think the North Sea sea is huge but sorry, the places where wind farms are build can easily simultaneous all be suffering similar winds.

                What makes you believe I'm forgetting that? I pointed out the use of fossil fuels currently as the primary means for energy storage because it looks like the advocates for renewable energy + storage have forgotten that the goal is reducing our reliance on fossil fuels. With every addition to wind and solar capacity we aren't seeing much in reduced use of fossil fuels, in fact we are often seeing it increase. Some of this increase is from a need to keep boilers at power plants hot or face power outages as

        The parc is 28GW faceplate, split about equally between on- and off- shore. There are a couple of periods a year when it produces well under 5GW per day for a week to ten days. There are several tens of days when it produces under 1GW for a day or two at a time. You can see the max and mins and average for a given period on the above site.

After a certain date once rulings have been made there needs to be a point of no return and the project happens.

        And that should be true not just for renewables but also for nuclear plants, hydro dams, pipelines, and all other major infrastructure projects.

    • Of course, we wouldn't want the view of multi-million dollar estates to be impacted by looking at a wind farm now would we?

      • Going by memory, the problem wasn't the view from the estates - the proposals placed the wind farms out far enough that the horizon would hide them.

        The problem was that these people occasionally like to go boating (sailing or motor) and could theoretically see the wind turbines if they went the right direction. And they objected to that.

        • Would they lose access to places they would normally boat or can you freely boat around the turbines?
          • That's getting to the limits of my knowledge.

            Still, some searching says that if you're fishing, you might actually prefer to be around the turbines - the support structures provide shelter to fish, so sea life tends to be more common around them.

            If you're in a motorboat, you're fine around them, but if you want "scenic" it seems people prefer scenes without them.

            If you're in a sailboat, you'd have to have extremely unusually high sails in order to actually have the blades be a risk. Most of them are going

                Beyond standard "don't run into stuff", it appears that your ability to boat around wind turbines is unaffected.

      Well, YOU explain why we only have wind if those things turn!

    • Wind kills some birds but no even the order of magnitude as NIMBYs seem to claim. Sadly, lots of human activity kills birds.
    • Wind power stopped really killing birds a while ago. Cats and windows are magnitudes more dangerous. Even then, it was more bats for a while. Still, they adjusted how turbines were built and how they operate and it pretty much fixed the problem. As I understand it, the growth of turbine sizes took care of a lot of the problem right there.

      Especially if you're looking at an ocean or sea based wind turbine that is far enough out that a very limited selection of birds will even encounter them.

    • Currently wind is out-producing solar almost 3 to 1 in the us: "The U.S. generated 683,130 gigawatt-hours (GWh) of electricity from solar (27%) and wind (73%) combined in 2022 - enough to power the equivalent of 64 million average American households."

    All the hot air produced there still goes to waste.

  • 2.6 gigawatts of clean energy... capable of powering over 900,000 homes. In just its first 10 years it should save customers $3 billion in fuel costs.

    So a house draws 2.8kW on average?

    900k customers, 87600 hours being 10 years, so 78GWh total

    $3b saving is therefore $3/78 so under 4c/kWh.

    Exciting?

    • Thank you!

      I saw the thermo article in Nevada where the average power per household was 1.5 KW. I don't know where they get these numbers. I guess that there aren't going to be many EVs charging.

      Also note that the savings was in 'fuel costs'. It doesn't say that the operation/electricity will be any cheaper.

    • Nameplate power rating divided by three is closer to the truth on average. Solar power name plate should be divided by four, if it's sunny, divided by 14 in heavy overcast. Don't forget to adjust for length of the day, about 7 hours useable daylight in the winter.

      My stove is rated at 11.2 kw. Winter days take about 60 kw-hr, during a cold snap (by local standards, not Wisconsin standards) it can reach 80 kw-hr per day.

      Yes I have a heat pump.

        Where are you getting this so-called information? My 4.2kW array (nameplate power), which is installed on a gently pitched roof with a north-south ridgeline, peaks out at about 3.8kW in the summer. That's about 90%, not the 25% you claim.

        Production on clear days varies from 28-29kWh/day in the summer to maybe 9-10kWh in the winter.
