Key Property:	No
Description:	Percentage mark-up applied to generator offer prices = (P - C) / C

Input

Generator Bid-Cost Mark-up as input applies a mark-up to Offer Prices equal to a percentage of the Cost Price.

Example

Generator	Property	Value	Band	Timeslice
Coal	Units	1	-
Coal	Max Capacity	300	MW
Coal	Min Stable Level	120	MW
Coal	Heat Rate	10	Gj/MWh
Coal	Fuel Price	4	$/GJ
Coal	Bid-Cost Mark-up	5	%	OFF PEAK
Coal	Bid-Cost Mark-up	25	%	PEAK

In this case the Offer Price in "OFF PEAK" is calculated as:

Offer Price = 10 × 4 × ( 1 + 0.05 ) = $42/MWh

and in "PEAK" it as:

Offer Price = 10 × 4 × ( 1 + 0.25 ) = $50/MWh

Bid-Cost Mark-up can be used with Mark-up Point in multiple bands to vary the mark-up percentage across the range of generation.

For more examples see the topic Generator Mark-up.

Output

Generator Bid-Cost Mark-up as output is the percentage Mark-up applied to Generator Offer Price and is calculated as:

Bid-Cost Mark-up (b) = 100 × ( Offer Price_b - Cost Price_b ) / Cost Price_b

where:

b indexes the Offer Quantity bands. It is expected that the number of offer quantity bands should be the same as the number of bid-cost mark-up bands. However, if the number of bid-cost mark-up bands is more than the offer quantity bands, then PLEXOS will throw a warning message and the bid-cost mark-up of the excess bands will be applied on the cost price of the last band.
