Building on our initial excel spreadsheet, in versions 1.0 - 1.3:

1. We added ancillary service revenues to the dispatch model, so we now have both

• Merchant only revenues
• And, merchant + ancillary revenues.

2. Fixed a bug in the run hours and generation production figures in the fundamental model outputs (previously these were showing too high due to the way subtypes were being aggregated up)
3. Added some alternative fundamantal low scenarios to the databook:

• Double the DSR, half the price
• Extend CCGT retirement
• Increase gas and carbon pricing by 20%
• Lower the BM dispatch rates
