Actually, quite a lot, but it's also a question about whether or not SAE makes some profit, or if it's a zero-sum play for them.
Anyway, if we assume a capacity factor of around 26%, that is,
6MW * 26% * 24h * 265 days ~ 13.7 GWh per year
The above is a computation based on some data that was available for a year, where SAE had all turbines (6MW) running for (almost) a whole year.
MeyGen
Phase 1: 6MW * 26% * 24h * 265 days ~ 13.7 GWh per year
Phase 2: 22MW * 26% * 24h * 265 days ~ 50.1 GWh per year
Phase 3: 34MW * 26% * 24h * 265 days ~ 77.4 GWh per year
In AR4 (the 22MW), SAE had a strike price around £175/MWh. So..
50,100 MWh/y * £175/MWh ~ £8.8m/y
77,400 MWh/y * £198/MWh ~£15.3m/y
In total, that is £24.1m per year from the CfD contracts, plus whatever they get for the original 6MW which is probably some £2.6m/y.
We look at a (theoretical) revenue of £26.7m per year for SAE.
How much these contracts are "worth", depends on different things. A CfD pays you the difference of what the market is willing to pay. So, if the market pays you £50/MWh, then the UK pays the missing £125/MWh to SAE. Hence the name "Contracts for Difference".
The important question is, imo, whether or not SAE is able to produce turbines even cheaper and lower operating costs. Because every £1/MWh they can safe, gets into their own pockets which is, in the end, profit for the company. It's subsidiesed, but it's a profit nonetheless, and it may (or may not) help SAE to produce additional turbines.
Perhaps even more important is the question of whether or not the UK decides to change the CfD schema slightly. They already see problems with the schema as other forms of energy struggle to compete (wind, solar). Inflation makes it hard for them to guarantee low prices. I assume it is the reason why this year's bid made by SAE is actually higher than last year's. We need tidal to become cheaper. Way below £100/MWh if it is ought to have a future.
But let's see. SAE needs more investments. Ideally from an institution or so. Their share price is completely destroyed which means they'll have a hard time getting their hands on cheap money and we all now, SAE does not need more debt.
