Very fast FCAS markets continue to grow

Very Fast Raise and Lower FCAS markets to start on 9 October 2023

Very Fast FCAS, because it operates at a faster timescale, can arrest the rise or fall in frequency more rapidly than the current fast service and therefore provides an avenue to mitigate the costs of needing to procure increasing levels of the existing fast service. The markets (raise and lower) are going live on 9 October 2023.
