| Description: | Marginal cost of energy in band |
| Detail: |
Generator Cost Price is the marginal cost of production excluding emissions. It is reported by band and is paired with Offer Quantity.
Cost Price is the offer that is used in dispatch if:
- no user-defined offer is given,
- the generator does not alter its bids due to gaming, and
- the generator does not have an emission cost.
The true marginal cost may vary across the band so the reported cost price is that at the mid-point of the band.
Please refer to SRMC, for details of how the marginal cost is computed at a megawatt point.
