DC EDR should always be dispatched for economics, when in island = 0, a dispatch of 0MW is most appropriate. DC EDR's are associated with one station that if it is disconnected SPP is not receiving the energy, thus a setpoint and dispatch mw of 0 is most appropriate. Severity 3: Medium 786Markets UI Validation: Demand bids (fixed only, not price sensitive) should be limited to be 110% of a historical peak load for the settlement location. Severity 3: Medium 789Markets UI The following issues occurred while submitting ST Non-Conforming Load Forecast for the Fall DST transition in the Markets UI. 1) Duplicate hour is not consistently displayed a.
