I agree LG it would make total sense for the longest serving andritz turbine to be the one taken out. But it looks like the ar1500.
Look at this pic ar1500 deployment pic. Bulbous nose; dark blade tips; shape of lifting lines.

Now look at the pic taken this week. I think that’s the same turbine.

The boat is still on site. they're changing the connector so it will take longer than a standard turbine deployment. if anyone has eyes on the boat then it would be good to know if the turbine is still on board when it leaves the site.
@granny you are describing the CFD. phase 1 was deployed under the RO which has no £ per MWh cap. what meygen gets will depend on details of their power purchase agreement with a supplier, but income per MWh should be about 5 rocs per MWh plus wholesale price. roc price is about £60 per MWh, wholesale has averaged about £300 per MWh last year, so they should get £500-600 per MWh last year. who knows, they might even break even.
Turbine operations at meygen require a notice be posted in advance on the orkney harbours website listing the vessel to be used and where and when the operation will take place. no notice, no op.

Thanks noisyboy9, sma43 - great find! Looks like the Dec and Jan figures found by sma43 are REGOs not ROCs. 1 REGO per MWh I think. If so the site generated 8704MWh in 2022. 1053MWh in Jan is 31% load factor for the three operating turbines.
Thanks @downdraft, it sounds like the 500kW turbine generated about 247MWh over a year in Japan, but that's a capacity factor of just 3% which is nothing to shout about.

The AR1500 was reinstalled last March. Perhaps we'll get an update soon.
The GWh generated by Meygen is impressive but as far as I can tell there's no way of knowing how much of that comes from the three Andritz turbines and how much from the one Atlantis/Proteus turbine. They've said that one of the Andritz turbines has been generating continuously for four years, which is impressive. But I've seen nothing that tells me how well the Atlantis turbine has performed. I might have missed it, but if their turbine was performing well you'd expect them to shout it from the rooftops.
Not that SAE have their own tech any more, but I've never yet seen firm evidence that the (now Proteus) turbine works very well either. I suspect that's why SAE got rid of this division. I'd be very happy to see this evidence if it does exist.
BEIS published a draft budget for all pots at this stage for AR4 but apparently not this time. Doesn’t mean tidal won’t get a minimum but it looks like we’ll have to wait till March to find out.
A minimum is essential because tidal (£178/MWh in AR4) can’t yet compete on price with floating offshore wind (£87/MWh in AR4) in pot 2. Fixed offshore wind and remote island wind have moved to pot 1.
@timaeus, you are obviously a close observer of this company so I'm hoping you can answer a question for me. I'm trying to figure out whether an SAE (now Proteus) turbine has ever worked well. Can you (or anyone) point me towards any evidence?
mister_tidal, from your link: "The balance of 10,300,000 options has been awarded to a group of senior employees considered key to the continuing development and success of the Group."
Seems like they have awarded options to senior staff?
