Formal title: Process following the Installation of Small Scale Third Party Generating Plant (Alternative to CP1260)

Current Status

CPC Consultation
Committee Decision


Npower raised CP1276. CP1276 takes CP1260 ‘Meter Investigation Process where a Site is capable of Exporting (microgeneration)’ as its starting point and uses it to develop a process that enables Import Suppliers to take the most appropriate course of action on receipt of a D0001 from an LDSO informing them that a site is capable of exporting. Unlike CP1260, this Change Proposal is not proposing to mandate Suppliers to carry out an investigation to determine whether the Meter has a backstop if they are already aware that the Meter at site has a backstop. In addition to this it allows flexibility for Suppliers/Meter Operator Agents to maintain current or agree new contractual arrangements.


CP1276 was submitted by npower on 30 December 2008. CP1276 was issued for Industry Impact Assessment as part of CPC00651 on 09 January 2009. CP1260 ‘Meter Investigation Process where a Site is capable of Exporting (microgeneration)’ 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 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 an implementation of no later than November 2009, the Panel noted a decision needs to be taken by April 2009.

CP1276 was presented to the SVG alongside CP1260 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.
