GTC A transmission flow limit more constraining than a Transmission Elementrsquos normal limit established to constrain flow between geographic areas of the ERCOT Transmission System that is used to enforce stability and voltage constraints that cannot be modeled directly in ERCOTrsquos transmission security analysis applications

Note This table lists how many times a constraint has been activated to avoid exceeding a GTC limit it does not imply an exceedance of the GTC occurred

Generic Transmission Constraints (GTCs) ndash January 2019

GTC A transmission flow limit more constraining than a Transmission Elementrsquos normal limit established to constrain flow between geographic areas of the ERCOT Transmission System that is used to enforce stability and voltage constraints that cannot be modeled directly in ERCOTrsquos transmission security analysis applications

Note This table lists how many times a constraint has been activated to avoid exceeding a GTC limit it does not imply an exceedance of the GTC occurred

Generic Transmission Constraints (GTCs) ndash January 2019

GTC A transmission flow limit more constraining than a Transmission Elementrsquos normal limit established to constrain flow between geographic areas of the ERCOT Transmission System that is used to enforce stability and voltage constraints that cannot be modeled directly in ERCOTrsquos transmission security analysis applications

Note This table lists how many times a constraint has been activated to avoid exceeding a GTC limit it does not imply an exceedance of the GTC occurred

Generic Transmission Constraints (GTCs) ndash January 2019

11

GTC A transmission flow limit more constraining than a Transmission Elementrsquos normal limit established to constrain flow between geographic areas of the ERCOT Transmission System that is used to enforce stability and voltage constraints that cannot be modeled directly in ERCOTrsquos transmission security analysis applications

Note This table lists how many times a constraint has been activated to avoid exceeding a GTC limit it does not imply an exceedance of the GTC occurred

GTC A transmission flow limit more constraining than a Transmission Elementrsquos normal limit established to constrain flow between geographic areas of the ERCOT Transmission System that is used to enforce stability and voltage constraints that cannot be modeled directly in ERCOTrsquos transmission security analysis applications

Note This table lists how many times a constraint has been activated to avoid exceeding a GTC limit it does not imply an exceedance of the GTC occurred

GTC A transmission flow limit more constraining than a Transmission Elementrsquos normal limit established to constrain flow between geographic areas of the ERCOT Transmission System that is used to enforce stability and voltage constraints that cannot be modeled directly in ERCOTrsquos transmission security analysis applications

Note This table lists how many times a constraint has been activated to avoid exceeding a GTC limit it does not imply an exceedance of the GTC occurred

GTC A transmission flow limit more constraining than a Transmission Elementrsquos normal limit established to constrain flow between geographic areas of the ERCOT Transmission System that is used to enforce stability and voltage constraints that cannot be modeled directly in ERCOTrsquos transmission security analysis applications

Note This table lists how many times a constraint has been activated to avoid exceeding a GTC limit it does not imply an exceedance of the GTC occurred

GTC A transmission flow limit more constraining than a Transmission Elementrsquos normal limit established to constrain flow between geographic areas of the ERCOT Transmission System that is used to enforce stability and voltage constraints that cannot be modeled directly in ERCOTrsquos transmission security analysis applications

Note This table lists how many times a constraint has been activated to avoid exceeding a GTC limit it does not imply an exceedance of the GTC occurred

Generic Transmission Constraints (GTCs) ndash January 2019

GTC A transmission flow limit more constraining than a Transmission Elementrsquos normal limit established to constrain flow between geographic areas of the ERCOT Transmission System that is used to enforce stability and voltage constraints that cannot be modeled directly in ERCOTrsquos transmission security analysis applications

Note This table lists how many times a constraint has been activated to avoid exceeding a GTC limit it does not imply an exceedance of the GTC occurred

Generic Transmission Constraints (GTCs) ndash January 2019

11

GTC A transmission flow limit more constraining than a Transmission Elementrsquos normal limit established to constrain flow between geographic areas of the ERCOT Transmission System that is used to enforce stability and voltage constraints that cannot be modeled directly in ERCOTrsquos transmission security analysis applications

Note This table lists how many times a constraint has been activated to avoid exceeding a GTC limit it does not imply an exceedance of the GTC occurred
