MP187 Incorporation of Target Round Trip Times and Target Success Rates into the SEC

As part of the MP122A solution (implemented as part of the February 2021 SEC Release), new SRV metrics reporting has been introduced. These reports measure RTTs but are then compared to the TRTs, as listed within the SEC. The DCC has advised, through the OPR Working Group , that to report on TRTs in real-time and at an SRV level would cost around £3.5m-£5m. OPR Working Group members were unsupportive of this approach.

For DCC-only performance metrics there are the TRTs as defined in SEC Appendix E and adopted into contracts with the DCC’s Service Providers. However, to create incentives against SEC Party metrics, target RTTs and target Success Rates are required. The DCC is raising this SEC Modification to develop and define these targets, and thus incorporate them into the SEC.
