North Sea Wind Farm Claims Title of World's Largest 56

The world's largest offshore wind farm is now fully operational, 55 miles off the coast of Yorkshire. The Hornsea 2 project can generate enough electricity to power about 1.3 million homes - that's enough for a city the size of Manchester. From a report: A decade ago renewables made up just 11% of the UK's energy mix. By 2021 it was 40%, with offshore wind the largest component. Hornsea 2 is part of a huge wind farm development by energy firm Orsted. "The UK is one of the world leaders in offshore wind," Patrick Harnett, programme director for the Hornsea 2 wind farm told BBC News. "This is very exciting after five years of work to have full commercial operations at the world's largest offshore wind farm."

    According to TFA, the wind farm produces power for $0.06/kwh, which is not too bad, but then compares it to gas generation at $0.52/kwh, which is nonsense. Gas generation is only that expensive because of a temporary surge from the war. There is no reason to put that misinformation into an otherwise informative article.

    • For the electricity cost per enduser(for all on aveerage), consumers pay, 28p per kWh. And now because of *things* that is going up to 58p.

      For gas, tied to electricity prices, the endusers pays 7p, which will increase on average to 15p per kWh.

      The article is basically a lie with numbers, written by some biased idiot.

      It's not looking like that war will end any time soon. Even if it ended tomorrow, would the price go back down to pre-war levels?

        Bonneville Dam produces power for 2.3 cents/kWh.

        Which is nice, but doesn't really help the UK very much.

      The problem in the UK is that the price of gas impacts the cost of electricity, this article [goodenergy.co.uk] has a good explanation.

      I live in Scotland, where up to 97% of domestic electricity is generated from renewables, the local dam provides sufficient hydroelectricity for the whole town. But we are still paying for electricity generated from non-renewable sources.

      Gas is as expensive as that at for the gas power plants.

      Who can say just how temporary it is going to be? Folks thought Kiev would be overrun in the first two weeks; the war has gone on for over six months with no end in sight.

      But the costs for the wind farm are just that - cost for renewable energy.
      There are hidden costs inflicted by fossil fuels that don't show up on the bill. Hidden costs payed by the environment in terms of CO2 emissions but also damages and pollution from mining. The hidden cost of prepping up authoritarian regimes with disastrous results, like we can see in the Ukraine war. The hidden costs to our health and shortened lifespan due to pollution to air and environment.

      Or a sustained market shift away from carbon fuel sources.
    • And if we continue to increase usage of renewables, we can take advantage of larger economies of scale and minimize reliance on fossil fuels, which is a net positive for both the environment and for geopolitics.

      Even when gas was relatively cheap, it was still much more expensive than current wind contracts are selling for. And even at the current price, it's less than half what nuclear costs.

      Wind is just so incredibly cheap, and it's getting cheaper. The only places where anything else can compete with it are where fossil fuels and nuclear get massive subsidies and externalize their costs.

  • The Hornsea 2 project can generate enough electricity to power about 1.3 million homes

    Is that when wind is at peak strength? What happens during doldrums or weather pattern changes (hello, climate change)? Is there sufficient battery backup power. Do there need to be fossil fuel plants available on standby should such situations arise?

      If you'd spent your youth holidaying on England's North Sea coast (which faces east) you would never, never, never even begin to consider the possibility of a day when the East wind is not howling at you at a remarkable rate of knots. You know why the vikings kept invading us? They could get here without rowing and at double speed.

      • Actually more triple speed. Fast replica of Viking boats do 14 - 20 knots.
        A typical pleasure boat does not even do 8 knots.

        Put on top: tidal currents, and the boat goes 30 knots or more. (Of course tidal current helps a modern pleasure boat as well)

        That's just the coast. Out to sea, 100m up in the air where the turbines are, the wind is even more consistent and a lot faster.

      The site is rated for 1.3GW. That's peak, not average. When the went is blowing, which is typical year round in the North Sea, everyone is getting cheap clean electricity. When the wind stops, you are paying market price for oil, gas, coal, or nuclear power. If you have enough renewables overlapping such as solar, geothermal, and tidal, you can rely less on fossil fuels for base load power. Even without that overlap from a mature green energy economy, every kilowatt you get from a wind turbine is fewer liters of oil you must burn.

      Every country needs to build much more nuclear power for our base load. There's no viable alternative other than rationing. Look at the map for Hornsea 2 and Dogger Bank and see how big less than 5GW of wind farm needs. And then realize space for viable sites will run out before we can replace all our oil, gas, and coal plants.

      • The grids also need to connect. It is possible to connect Canada to Iceland to Greenland to Europe. Then all this nonsense about "when the wind is not blowing" or "the sun is not shining" really goes out the window.

        ... which is very rare (it's the North Sea), you will get your electricity from another wind farm in another part of the country. Yes, that means that the 1.3GW figure is deceptive, but there is always wind somewhere in the UK.

        • The wind doesn't blow in the UK... it sucks!
        • Yes, that means that the 1.3GW figure is deceptive
          It is not deceptive. It is the peak power.
          Just like in any other power plant on the planet.
          Or do you think a 500MW nuclear power plant is running 24/365 at peak? Hint: it is not.
          They usually run at 85% - 90% peak, and are offline every 3 years for half a year.

      • The capacity factor for current turbines is good, at least. The new 12MW up to 64%, although it depends too on location and how turbines are placed relative to each other (see comment by Joce640k). I can't remember exactly which turbines Hornsea II uses. In the UK as a whole the wind power contribution is 12-25% in any given month. If you look at Scotland, though, it is at 99% low carbon sources net, which does include some trading in either direction with England and now Norway in either direction. With su
      • Energy storage, combined with grids changing to rely less on a single source provider of base load for an area, mitigate the concern about the sun or wind not shining or blowing all the time.

        The wind never stops out in the North Sea. Never in recorded history. Name a day when you think it stopped, the weather data says otherwise.

        Modern offshore wind has a capacity factor of about 65%. That compares pretty well with other sources, e.g. nuclear is around 70%, down to 50% in France due in part to the hot weather.

    • Why pretending to be an idiot?

      The plant produces X kWh over a course of a year, which is the amount 1.3 million homes consume over a year.

      No idea what your silly questions are aiming at. If you wanted answers you would write a letter to the plant owner and not ask stupid, idiotic, no brainers on /.

  • Where are the hourly power generation graphs for these phenomenal windmill farms? Certainly that data must exist somewhere, right?

    Come on man! Don't give me a Feel Good News Story. Give me some real-world product data to examine.

    Then we can all see if these phenomenal windmill farms are really all they are cracked up to be.

    Or is the UK Government trying to pull the blades over our eyes? Trying to cover up the facts that Soylent Green is made from people?
