Sheet 5 of 5 General notes Power Producers when making the daily submissions of Availability to OETC and PWP will address the following factors. Most regular issues will be covered by responses in Table 1 using heading codes from Table 4. All other issues will be tabulated on a CDGenset/ Desalination Unit basis in Table 3.

1. CDGenset basic data;

2. Minimum Generation;

3. Maximum Generation and/or Desalination Unit increase in output above declared Availability;

4. CDGenset minimum on time;

5. Minimum shutdown time;

6. CDGenset and/or Desalinating Unit inflexibility (inflexibility description, start date and time, end date and time, MW, m3/h);

7. CDGenset Synchronising intervals (hot time interval, off-load time interval);

8. CDGenset Synchronising output MW;

9. Desalinating Unit startup intervals (hot time interval, off load time interval);

10. CDGenset Desynchronising intervals;

11. Desalinating Unit shut-down intervals;

12. Desalination Unit basic data;

13. Minimum water production;

14. Maximum water production;

15. Constraints on CDGenset output for range of associated Desalination Unit outputs;

16. CDGenset two shifting limitation;

17. CDGenset Synchronising groups;

18. CDGenset run up rates with MW breakpoints;

19. CDGenset run-down rates with MW breakpoints;

20. CDGenset loading rates covering the range from Minimum Generation to declared Registered Capacity; and

21. CDGenset de-loading rates covering the range from declared Registered Capacity to Minimum Generation.
