Column Type Description e42950d3
ADJUSTED_COST Nullable(Float64) The adjusted cost of the constraint for this service, after the regulation/contingency split
BASE_COST Nullable(Float64) The base cost of the constraint, before the regulation/contingency split
BIDTYPE LowCardinality(String) DUID offered type
CONSTRAINTID LowCardinality(String) ConstraintID join to table GenConData
CONSTRAINT_ENABLEMENT Nullable(Float64) MW enabled for this bid type within the constraint
INTERVAL_DATETIME Nullable(DateTime64(3)) The trading interval date and time of the dispatch interval that was processed by the constraint FCAS processor
LHS Nullable(Float64) Constraints summed LHS - aggregate LHS Solution values from the physical run from the DISPATCHCONSTRAINT table
MARGINALVALUE Nullable(Float64) Shadow price of constraint from the DISPATCHCONSTRAINT table from the physical run.
PREDISPATCHSEQNO Nullable(Float64)
P_REGULATION Nullable(Float64) The adjusted marginal value of the constraint for FPP recovery (blank for constraints without REG terms)
REGIONAL_ENABLEMENT Nullable(Float64) The dispatched MW for the bid type inside the region from the physical run of the DISPATCHREGIONSUM table
REGIONID LowCardinality(String) Region identifier
REGION_BASE_COST Nullable(Float64) The regional payment allocated to the constraint for the interval pro-rated based on marginal value ratios over the binding constraints for that service in that region (this is an intermediate calculation to get to the base cost)
RHS Nullable(Float64) Constraints RHS value used in the solution - may be either dynamic (calculated) or static from the physical run from the DISPATCHCONSTRAINT table
RRP Nullable(Float64) Bid type prices for the region coming from the pricing run of the DISPATCHREGIONSUM table
RUNNO Nullable(Float64) The dispatch case run number that has triggers the constraint FCAS processor run
RUN_DATETIME Nullable(DateTime64(3)) The run date and time of the dispatch case that triggers the constraint FCAS processor run
processed_at DateTime64(3)
source_zip String
