Construct a feasible offer
Price bands describe willingness to generate or consume, while availability and ramp constraints limit feasible dispatch. A price change does not create physical capacity. Rebid records should connect changed intentions to evidence and the relevant rules.

The lesson
6 chaptersBrowse the chapters
01Read a price–quantity offer without confusing its columns
| Band | Incremental MW | A$/MWh | Cumulative MW |
|---|---|---|---|
| 1 | 30 | 20 | 30 |
| 2 | 40 | 50 | 70 |
| 3 | 30 | 90 | 100 |
| 4–10 | 0 | Unused in this exercise | 100 |
02Apply availability and ramp limits before promising output
03Keep offer cost, market price and metered revenue separate
04Represent changed intentions without inventing capacity
05Build the chronology and preserve the response
06Prepare an offer-change handover
Check your understanding
What should the handover say if the derating record is missing?
Show reasoning
Keep the physical capability unresolved and request the supporting operational evidence.
A price-band edit or a successfully uploaded file is not proof of the plant's available MW.

Key terms in plain English
- MW
- Megawatt: a measure of power, or how quickly energy is transferred. A plant's maximum MW is not its actual output in every interval.
- Dispatch
- The operational process of determining output and consumption targets, subject to offers, demand and system constraints. A target is not a meter reading.
