Sanddancer Posted October 20, 2021 Report Share Posted October 20, 2021 I'm after some advice about wind turbines, I'm thinking this is the best option as solar is out of the question. It would be used to charge the batteries and run the fridge, anyone tried this?. Link to comment Share on other sites More sharing options...

Before solar became cheap enough some tried but please ignore the makers output figures, they are for a near gale and with no flukes in the wind. Ideal for off shore but inland the wind tends to slow and too fluky. Carefully check the output data at long term wind speeds likely in your area. you will almost certainly find a larger solar array will do better, even in the winter. Solar will provide next to nothing in very cloudy winter days but wind will be similar at no or low wind speeds. Link to comment Share on other sites More sharing options...

Even the huge offshore windfarms get becalmed - it was only a few days ago that Southern England had no leccy because there was no wind and they had to turn on the gas power stations, at the same time Scotland had to shut down their wind tubines becasue they were producing too much and, surprise surprise, there is no link between Scotland and England to 'ship' the leccy down South.

I find that hard to believe. More likely the wind was blowing too hard in Scotland so the windfarms had to be shut down meaning there was no leccy to export to England. I shall enquire of my sister-in-law who used to balance supply and demand at National Grid. 8 minutes ago, Tony Brooks said: Yet private companies want to build an undersea inter connector but not one over land.

This came up on Facebook and I looked into the spec, for a vertical 600Watt turbine and it needed a wind speed of 59MPH for full output. 26 minutes ago, George and Dragon said: I find that hard to believe.

George and Dragon Posted October 20, 2021 Report Share Posted October 20, 2021 National Grid has a map that appears to show two connections between England and Scotland. https://www.nationalgrid.com/uk/electricity-transmission/network-and-infrastructure/network-route-maps There's also a world map https://openinframap.org/#5/54.36/-3.13 3 hours ago, ditchcrawler said: Come to the Norfolk Suffolk coast and have a look on a still day, you will see them just sitting if its not too misty. Undoubtedly. The bit I was struggling to believe was that there's no way to move electricity between Scotland and England.

I read that to mean they couldn't ship the leccy down south so they had to shut the windfarms down. Maybe the postman lost the letter.

Sis-in-law says: National Grid are working on plans to boost the existing connections from Scotland to England using Interconnectors from Coast to coast. They were calling them ‘boot straps’. One will be from Peterhead to Drax. They will officially be called Green link 1 and 2 and are expected to get planning permission in 2022/23. National Grid don’t own the electricity system in Scotland but they run it for Scottish & Southern. We really rely on wind and solar panels and NG have to manage constraints like frequency in set parameters. So I can see why they had to turn on gas stations. I guess managing frequency in Scotland meant they had to turn off wind farms to balance the system. 2 Link to comment Share on other sites More sharing options...

Reading more about them, should be online by 2027. They also have some new forms of inertia coming online in the next few years to manage the frequency and voltage better, so by 2025 they recon they'll be able to turn off all the gas if there's enough wind/solar around - at the moment they need to pay wind farms to shut down instead. Hopefully will make the bills a bit cheaper 😉 Link to comment Share on other sites More sharing options...

You saw a few inland boats with wind turbines in the '90's and '00's, but very few now. Since then, the cost of solar PV has plummeted, so most boaters use that. 1 Link to comment Share on other sites More sharing options...
