GENMAP Packet Defined
Unit and Associated Resource Nodes: The GENMAP’s first page contains the mapping of generating units to Resource Nodes, or Settlement Points. Information such as the Unit’s and Resource Node’s substation, as well as the Resource Node’s voltage level and Connected Devices are listed. The Connected Devices are of all of the devices at a connectivity node where the Resource Node is located. Note that the Resource Node may not be located at the same connectivity node as the generating unit.
Unit-Associated EPS Meters: The Unit-Associated EPS Meters page shows the mapping of each generating unit to one or multiple EPS Meters. Information such as the Unit and EPS Meter’s substation, as well as the EPS Meter’s Meter ID, RID and Connected Devices are given. The Connected Devices consist of the devices at the connectivity node(s) where the EPS Meter is located. Note that a Unit-Associated EPS Meter may be located at a different substation than its mapped generating unit.
Unit-Associated EPS Flow-Calculation Modeling: The Unit-Associated EPS Meter Flow-Calculation Modeling page shows the mapping between a Unit-Associated EPS Meter and its associated conducting equipment used in the Flow-Calculation. Information such as the Unit and EPS Meter’s substation, Meter ID, RID and Connected Devices are given. The Flow-Calculation’s direction at the connected device is also given. See Explanation Verifying EPS Meter Flow-Calculation Modeling below.

•The one-lines are provided for two reasons – one to verify the accuracy of the meter and unit location on the one-line; the second as a tool to verify the mapping.•Each node and meter will have reference “Connections”. Each item listed in the connection column will refer to all equipment electrically connected to the node or meter point. These connections are represented as [CB]1234 or [XFMR]U1 and are shown on the one-line screenshots. •The connections column identifies the equipment type by offsetting the type in brackets, such as [CB]1234, where [CB] refers to the equipment type Circuit Breaker. The list below identifies the common equipment types:
o[XFMR] Transformer o[CB] Circuit breaker o[DSC] Disconnect (switch) o[UN] Generation Unit o[LN] Line o[LD] Loado[SERIES] Series Deviceo[SVC] Static-Var
Note: Transformer naming convention in GENMAP pkg is power transformer concatenation and may not match names provided in the RARF.
•The one-line screenshot uses several colors to define the operating voltage of the equipment and buses represented. The list below identifies the voltages associated with each color:
oPurple: 345kV oGreen: 138kV oBlue: 69kV oPink: Other voltages
