Several updates or improvements in the October update to Signal:
- Updated all of the input data so it uses data to 26th September 2022, which previously was up to mid-July 2022, including a new gas curve.
- Improved the smoothing of the gas curve, which is delivered in monthly intervals.
- Use the NG ESO shorter-term forecast for the dispatchable plant data, for the first two weeks of the curve. The remainder of the curve is using the 2 week - 3 year forecast (as before).
- Reduced the FFR requirements so that they begin stepping down from January 2022. This is in line with the latest comms from National Grid.
