Sparked by altolusso's post I've done a bit of digging into the grid connection - thoughts and corrections welcome.
The lease is for 398MW and the consent is for 86MW. The grid connection is separate to both of these.
The existing connection is for 14.9MW (source: and various company announcements). This is shared with the 9.2MW Lochend wind farm (source: Atlantis press release July 2016). There might be a bit of spare capacity on this but I assume not a lot.
The remaining grid connection capacity is actually just grid connection *agreements* - the physical connection capacity is not yet in place. There are five separate agreements totalling 287MW. The additional capacity and expected connection dates break down as follows (source: SAE press release 11 June 2024 and TEC register).
- Tranche 1, 28MW, 01/04/2027
- Tranche 2, 43MW, 01/04/2028
- Tranche 3, 83MW, 01/04/2028
- Tranche 4, 83MW, 01/04/2028
- Tranche 5, 50MW, 31/10/2030
The UK grid is massively oversubscribed, particularly in Scotland, and grid connections are often delayed due to delays in network reinforcement. Since this is a common occurrence and outside the generator's control the CFD start date can be pushed back to allow for this delay. On top of this, the NESO reform process is reprioritising the grid connection queue which means some projects will be brought forward and others delayed, possibly by many years.
I don't know where the Meygen grid connection agreements stand in relation to the NESO process but I wouldn't be surprised if these connection dates changed. I assume that SAE will keep us updated of any progress or delays.
