Description:Cap on Reserve Price for settlement

Reserve Price Cap is the cap on Reserve Price for settlement.

The Reserve Price is set by the dual variable value (shadow price) associated with the constraint that Provision must equal or exceed the requirement (or Risk). That shadow price generally takes a value between zero and the VoRS. Price Cap allows you to cap the Price at a lower level than VoRS, while using VoRS to indicate the priority for relaxation of Reserve requirements between multiple classes of Reserve.

Example

In this example the Reserve "Spin Up" has lower priority in terms of Shortfall than "Reg Up" but the Price output are capped at the same value.

Reserve Property Value Units
Spin Up VoRS 500 $/MW
Spin Up Price Cap 300 $/MW
Reg Up VoRS 1000 $/MW
Reg Up Price Cap 300 $/MW
