Smart and Advanced Metering and Consultations
Advanced metering is defined as a meter which, either on its own or with an ancillary device, stores measured electricity consumption data for multiple time periods; and provides remote access to such data by the licensee.
In April 2009 the government introduced a requirement for Suppliers to provide advanced metering for larger non-half-hourly read electricity and non-daily read gas sites in the non-domestic sector. For electricity this affects about 170,000 sites in Profile Classes 5 to 8. The requirement applies to new and replacement meters, with advanced metering to be installed for all such sites by 06 April 2014.
In September 2008, at Ofgem’s request at an interoperability workshop, we investigated interoperability issues for sites with advanced metering. With a group of industry experts, the Advanced Metering Expert Group (AMEG), we developed the Advanced Metering Operational Framework: Profile Classes 5 – 8. The Supplier Volume Allocation Group (SVG) endorsed the framework in November 2008, and the framework has since been implemented via a number of change proposals and Approved Modification Proposal P230.
|CP1273 Changes to the scope of CoP10 to cover current transformer operated Meters|
|CP1274 Transfer of Meter Technical Details|
|CP1275 Supplier Agents – Access to Meter Protocols|
Modification Proposal P230
P230 Enabling Interoperability through the use of CoP10 and CoP5 Metering was implemented on 26 November 2009. This mandates the use of Code of Practice 5 or Code of Practice 10 meters for sites covered by the new licence requirement.
In October 2008, the Government announced its intention to mandate electricity and gas smart meters for all households. Smart metering functionality is yet to be finalised, but is likely to include:
- providing accurate reads remotely for defined time periods
- two-way communications
- support for a range of time of use tariffs
- disabling and enabling supply remotely
- ability to measure export; and
- ability to communicate with a measurement device within a micro-generator.
BSC Review of Smart Metering and Automatic Meter Reading (AMR)
In 2006-2007, we carried out a BSC Review of Smart Metering and Automatic Meter Reading (AMR) with the help of an industry expert group. The aim of the review was to identify any changes required to the BSC and Code Subsidiary Documents (CSDs) to:
- facilitate market driven smart meter and AMR rollout without introducing any undue risk to Settlement; and
- enable Settlement to exploit the benefits of smart meters and AMR.
The review conclusions are published in SVG Paper 92/08.
The review group recommended the following changes, which have all been implemented.
|CP1251 Inferior / Inappropriate Peripheral Devices shall not be used to Collect Automatic Meter Readings|
|CP1252 Reading Submission Frequency for Remote Meter Readings|
|CP1253 Remote Reading Assurance|
|CP1254 Prevention of Unauthorised Access to Smart Meters and Automated Meter Readings|
|CP1261 Introducing Metering Code of Practice 10 to facilitate smart metering in the Half Hourly (HH) market|
What will Smart Metering mean for Settlement in the longer term?
The BSC Review of Smart Metering and AMR also identified a number of longer term issues which need to be addressed once the direction of smart metering in the domestic and small and medium sized businesses sector is clearer. This includes considering how industry processes might need to evolve to reflect the new opportunities for interaction with smart meters by Suppliers and agents, and to best exploit the benefits that that the new technology will bring. considering what form this evolution might take.
Will the BSC profiling arrangements need to be changed to support dynamic tariffs and demand side management?
SVG Paper 92/09 considered this question in September 2008.
We are committed to assisting government in its consultations on smart and advanced metering by providing information about the balancing and settlement implications of the relevant proposals. Here are our responses
