Right now, mainland Britain has got almost enough wind and solar power to meet our electricity demand. Add in the power from nuclear and a small dash of gas (used solely to maintain enough mechanical inertia to stabilise the grid) and we are having to export 4 […] [Original post on mastodon.green] - ThreadSky

@christineburns But the fact that we would one day need frequency control other than generators which also act as mechanical flywheels has been known forever. Which raises the question - why hasn't it been built already?

@TimWardCam @christineburns
It's being built. Here's a NESO article from 2022.

If you look back through past summers' generation history, you'll find the minimum amount of gas generation […]

@TimWardCam @sheddi I had noticed it going down and, if I recall correctly, I’ve seen gas creep below 2GW this year. Here’s an example from March, when it dipped to 1.98GW. I commented at the time that if they’d cranked nuclear up to the max they might just […] https://mastodon.green/@christineburns/114573966660562372

A bit more N wont do what the pathfinders are needed for.

Not sure on the low this yr - its not been a great yr - but eg last yr we saw gas at lows in the ~700s MW

@christineburns The lack of "grid-forming" solar and wind installations in Spain was part of why it was so tricky for them to get their grid started back up again: they were the only systems that didn't require power to start making power, but they expected the fossil fuel generators nearby to […]

@spacehobo I saw something recently on YouTube about black start strategies for total grid loss and how the services involved in that are rehearsed regularly. It’s a fascinating topic.

ivmd we'll ever see a full BS. But a lot of work is ongoing to manage the systems to do so. eg

@christineburns Ooh, that's interesting. Do you have any more info on the grid-forming thingy on Dogger Bank?

This post has given me some positivity about the UK, after so much disappointment with this country. Thanks Christine.

@christineburns In New Zealand here we unfortunately don't have any neighboring countries to export to but our power generation has been hovering between 78% to 98% renewable since I started regularly checking in 2019. Here we were just lucky enough to have […] https://social.apcn.nz/@addressforbots/114569218477759223
