Appendix C: Utility and Unit Identification Codes Utility Identification Code NERC assigns each utility participating in the Generating Availability Data System (GADS) a unique identification code. This three digit code allows each system's data to be uniquely catalogued and filed in the database. This appendix contains a list of the codes for each utility system presently participating or assigned a NERC-GADS utility code. Unit Identification Code Each utility participating in GADS assigns unique identification codes to its units. This three digit code allows each unit's data to be uniquely catalogued and filed in the database. Note that each utility must assign identification codes for individual units based on the following criteria: Table 1: Unit Identification Codes Unit Type Coding Series Fossil (Steam) 100 - 199 (Use 600-649 if additional numbers are needed) Nuclear 200 - 299 Combustion Turbines (Gas Turbines or Jet Engines) 300 - 399 (Use 700-799 if additional numbers are needed) Diesel Engines 400 - 499 Hydro/Pumped Storage 500 - 599 (Use 900-999 if additional numbers are needed) Fluidized Bed Combustion 650 - 699 Miscellaneous 800 - 899 (Multi-Boiler/Multi-Turbine, Geothermal, Combined Cycle Block) NERC | 2021 GADS Data Reporting Instructions | January 2021 C-1 Appendix C: Utility and Unit Identification Codes Northeast Power Coordinating Council (NPCC) Northeast Power Coordinating Council 1040 Avenue of the Americas (6th Avenue) 10th Floor New York, New York 10018-3703 212-840-1070; 212-921-1040 NPCC Utility Code Utility Name 003 Ontario Power Generation, Inc. 004 NB Power 008 Emera Energy Inc. 043 Nova Scotia Power 098 Dynegy Generation 100 Brookfield Power 102 Constellation Energy 105 Central Maine Power Company 107 Connecticut Light And Power Co. 108 Consolidated Edison Co.
