Dispatch Signals and Metering Data
WPD will send dispatch signals 15 minutes ahead of when we need to utilise your flexibility asset. Minute by minute metering data for that asset is to be sent back to WPD.
To facilitate this exchange an Application Programming Interface (API) must be built by the contracted participant. The API has both Incoming and Outgoing signals, covering start, stop, metering and emergency stop, for each service in each zone.
Further information on this can be found in the API Guide
