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.
