> We know that the workings of a 2MW tidal turbine are essentially the same as a 2MW wind turbine, and it is also common knowledge that wind installation costs are around 1M€/MW.
If this estimate is realistic, then my estimate for £10m/MW is probably very much outdated to say the least.
But let's continue and look at the effectiveness of those turbines. in 2018, the four turbines produced 8 GWh and in 2019 it was 13.8 GWh. Now, I assume that 2019 was the year which saw all of them running without outage.
If I don't make an error here we have a capacity factor of 13800 [MWh/y] / (6 MW * 24h * 365d) = 26.25%. That's not bad, but it's also not outstanding. Not being an expert here, but wind and solar can achieve the same efficiency (yes, yes, I know, they are not as reliable as tidal stream).
Anyway, with a strike price of £ 178.54 / MWh, a year like 2019 would bring 13800 * 178.54 = £ 2.46m. Divided by 6 MW, that would be £ 410.6k / MW deployed.
So, theoretically, we should see £ 410.6k * 28 MW = £11.5m in revenue per year for the upcoming 28 MW plus the £ 2.46m bringing us to a total of £ 13.96m / year for the 28 MW (Phase 2) + 6 MW (Phase 1) = 34 MW deployed.
However, and that would be the interesting answer here, it would mean that if the cost is truly £1m/MW, we'd have covered the cost of those turbines in 28 [£/MW] / £ 13.96 = 2 years.
If this quick computation is anywhere near the truth of what we're facing, then this should mean that the new CfD AR4 round actually be a cash positive. Even if my computations are somewhat correct, those numbers are probably wrong because they are 1) a little dated and 2) variable.
In theory, this should allow SAE to finance new turbines on their own. At least one or two per year - without external funding - that's the point where I have to question everything I wrote so far..
but let's assume all this is somewhat true: How could this affect SAEs strike price in the upcoming CfD AR5? This is one of the main things I see going for SAE.. the rather good chance that they can secure rounds in the future which could (!) lead to a snowball effect.
