Today’s LiveWire Spotlight addresses MOD-028-2, which will become the NERC standard or record governing the derivation of short term transmission system Transfer Capabilities using the Area Interchange Methodology. It includes minor updates to R3 which specifies the types of data that must be incorporated in the Transmission Operator’s TTC calculations. Of interest to all our Clients is an examination of the effectiveness of the rapid interpretation process.

MOD-028-2 will take effect in the U.S. on 10/1/2013. All Transmission Operators must assure that their Total Transfer Capability calculations are consistent with Requirement R3 by that date.
