Price per Unit of Energy, i.e., Power times Duration Level of Energy Quantity of Power One type of EndDeviceAsset is a MeterAsset which can perform metering, load management, connect/disconnect, accounting functions, etc. Some EndDeviceAssets may be connected to a MeterAsset. The EndDeviceAssets are the physical device or devices which could be meters or other types of devices that may be of interest The MeterAsset is the physical device or devices that performs the role of the meter A pricing node is directly associated with a connectivity node. It is a pricing location for which market participants submit their bids, offers, buy/sell CRRs, and settle. An aggregated pricing node is a specialized type of pricing node used to model items such as System Zone, Default Price Zone, Custom Price Zone, Control Area, Aggregated Generation, Aggregated Particpating Load, Aggregated Non-Participating Load, Trading Hub, DCA Zone A customer ServiceLocation has one or more ServiceDeliveryPoint(s), which in turn relate to Meters. The location may be a point or a polygon, depending on the specific circumstances. For distribution, the ServiceLocation is typically the location of the utility customer's premise. Logical point on the network where the ownership of the service changes hands. It is one of potentially many service points within a ServiceLocation, delivering service in accordance with a CustomerAgreement. Used at the place where a meter may be installed. The Transport Interface delineates the edges at either end of a transport segment. The Node is a place where something changes (often ownership) or connects on the grid. Many nodes are associated with meters, but not all are. The mRID identifies the physical device that may be a CustomerMeter or other types of EndDevices.
