Formal title: Increase opportunity to update the NMTES

Current Status

CPC Consultation
Committee Decision
Awaiting Implementation


The National Measurement Transformer Error Statement (NMTES) is a list of generic accuracy errors for some types of Metering Equipment used in Settlement. The Technical Assurance Agent (TAA) uses this information when site visits are made to assess compliance with a Code of Practice (CoP) where individual test results are not available. The items currently listed are not representative of all of the equipment in use and the mechanism for amending the list is not practical. CP1250 proposes that BSCP515 section 3. 10. 1. 1 should be change as follows: ‘Submit a minimum sample of 50 CT or 10 VT errors obtained from test records. ‘


CP1250 was raised on 27 August 2008. CP1250 has been issued for Participant Impact Assessment via CPC00642 on 05 September 2008. CP1250 was presented to the SVG 0n 04 November 2008. The SVG approved CP1250 for inclusion in the February 2009 Release. CP1250 was implemented on 26 February 2009 as part of the February 2009 Release.
