CP1260 – Meter Investigation Process where a Site is capable of Exporting (microgeneration)
Formal title: Meter Investigation Process where a Site is capable of Exporting (microgeneration)
Current Status
Summary
The purpose of this CP is to ensure that Suppliers are aware when an Import Meter is at risk of capturing Export energy (i. e. when microgeneration will be or has been installed on a site) and to create a process for checking (and if necessary, replacing) the Import metering. There is no requirement to fit an Export Meter.
Progression
CP1260 was raised on 27 August 2008 fromDCP0030.
CP1260 has been issued for Participant Impact Assessment via CPC00642 on 05 September 2008. CP1260 was presented to the SVG on 04 November 2008 for a decision on progression. The SVG did not reach a decision. CP1260 was presented to the SVG on 02 December 2008 for a decision on progression. The SVG were unable to reach a decision on whether to approve or withdraw the CP. CP1260 was presented to the BSC Panel (Panel paper 151/10) at its meeting on 15 January 2009 as the SVG could not reach unanimous agreement on its progression.
The Panel noted that the disagreement related to which data flow should be used to ensure a Supplier has the appropriate metering for any site capable of exporting. The Panel noted that no participant had set out any clear information on actual costs or complexity of using the different flows and therefore there was insufficient understanding of the perceived benefits of CP1260. The Panel noted that, since SVG last met,CP1276 ‘Process following the Installation of Small Scale Third Party Plant (Alternative to CP1260)’ had been raised. CP1276 sets out a different solution to resolve the same issue that CP1260 seeks to resolve.
As a result, the Panel have remitted CP1260 back to the SVG. The Panel have asked the SVG to compare the merits of both Change Proposals in parallel as and agree a solution. In order to allow SVG to make an informed decision the Panel noted that SVG need clear details on the costs and complexity associated with each solution from a participant system/process point of view. To allow for a November 2009 implementation, the Panel noted a decision needs to be taken by April 2009.
CP1260 was re-issued for Impact Assessment by Industry alongside CP1276, via CPC00651 Addendum on 16 January 2009. CP1260 was presented to the SVG alongside CP1276 for decision on progression on 03 March 2009. The SVG made a unanimous decision to reject both CP1260 and CP1276. The SVG noted that Suppliers still have the (Code) obligation to ensure that an Import Meter doesn’t run backwards when a site is exporting. The SVG agreed that although microgeneration is likely to increase, the role out of Smart/Advanced metering will resolve this issue in the long term. The SVG agreed that the cost of mandating how Suppliers ensure Import Meters don’t run backwards is not outweighed by the (potentially short term) benefits of increased consistency for Meter Operators.
