CP1361

Formal title: Removal of Extreme EACs

Current Status

Submission
Assessment
CPC Consultation
Committee Decision
Rejected

Summary

CP1361 was raised by ENW Ltd and seeks to place an obligation on Non Half Hourly Data Collectors (NHHDCs) to replace extreme EACs following a Gross Volume Correction (GVC), if the forward Estimated Annual Consumption (EAC) is demonstrably inconsistent with normal generation or demand for that Metering System and is likely to lead to failure to validate subsequent readings. This is currently an optional requirement. Making this step mandatory will ensure that extreme EACs are removed from Settlement data thereby reducing volatility between Settlement runs and the consequential uncertainty that results for Licensed Distribution Systems Operators (determining regulated allowable revenue) and Suppliers (Distribution Use of System costs incurred).

Progression

CP1361 was raised and issued for industry impact assessment via CPC00706 on 25 November 2011 with responses  due back on 22 December 2011. CP1361 was presented to the SVG at their 31 January 2012 meeting, where the SVG requested further data analysis from Elexon. 

Elexon provided the requested data analysis to the SVG at their meeting on 28 February 2012.  It was there that the SVG decided to place CP1361 on hold pending the outcome of P274.

P274 was rejected by Ofgem on 29 January 2013. Elexon presented an information paper to the SVG at their 5 February 2013 meeting to update them on the proposed progression of the CP. CP1361 was  rejected by the SVG at it meeting on 5 March 2013.
