Water Industry - Scottish Government Investment Group - Development List performance progress report: quarter two 2023-2024

2. Summary of Current Investment Maturity

The current outturn forecast of investment over the 6-year investment period is provided below (Figure 1). This shows the maturity of investment across the period and how it has developed since the previous quarter (Q1 23/24 versus Q2 23/24). Appendix A contains the inflation assumptions.

Live Investment is categorised by Plan (Gate 30-60), Prepare (Gate 70/80), Deliver (Gate 80 -120) and Non-live Investment (Pre-Gate 30). The “Deliver” category includes both projects which have been committed for delivery (post Gate 90) and those at detailed design stage but not yet committed. The data also includes allowance for risk associated with the potential additional cost increase of the SR15 Completion programme.

The level of investment in delivery for 2023/24 has increased by £80m to £873m since previously reported in Q1 (blue bars). This is as a result of projects continuing to mature through the Plan and Prepare phases and is in line with what is necessary to achieve the planned level of annual investment. The total of investment in Delivery is now £3.3bn.

The combination of the Live and Non-Live Investment can exceed the Planned Investment Level shown on the figures as interventions can be initiated but will not necessarily be committed. A tabular view of the data represented in the figure is available in Appendix B.
