(bid_group:price_dimension)=
### price_dimension
Number of prices in the resulting bid matrix (xUnit: NO_UNIT, yUnit: NO_UNIT)


(bid_group:time_dimension)=
### time_dimension
Number of time steps in the resulting bid matrix (xUnit: NO_UNIT, yUnit: NO_UNIT)


(bid_group:bid_start_interval)=
### bid_start_interval
Index of the first time step in the bid matrix (xUnit: NO_UNIT, yUnit: NO_UNIT)


(bid_group:bid_end_interval)=
### bid_end_interval
Index of the last time step in the bid matrix (xUnit: NO_UNIT, yUnit: NO_UNIT)


(bid_group:reduction_cost)=
### reduction_cost
The cost of reducing the full bid matrix to the desired number of points (xUnit: NO_UNIT, yUnit: NO_UNIT)


(bid_group:bid_curves)=
### bid_curves
Resulting bid matrix (xUnit: NOK/MWH, yUnit: MWH)


(bid_group:bid_penalty)=
