Metering data from the Trading Operations Report

Glossary

The page below details the number of Electricity Metering Systems that are in the Half Hourly or Non Half Hourly Markets. The numbers of certain types of metering systems are also highlighted in this report; these are microgeneration export metering systems and radio teleswitch metering systems.

This data is acquired from BSC Agents and inputted to the Trading Operation Monitoring Analysis System (TOMAS) database.

The graphs may take a couple of seconds to load. To expand the graphs featured on the page, tap the double-headed arrow in the bottom right corner of the graph.

Metering Systems in the markets

The charts below show the number of Half Hourly (HH) and Non-Half Hourly (NHH) Metering Point Administration Numbers (MPANs) for the past year. A GSP Group filter is included to see the number of Metering Systems in each GSP group.

Generally there is an MPAN assigned for each separate metered supply to premises settled through SVA. The chart therefore provides a high level overview of the growth (or otherwise) in the Half-Hourly and Non-Half Hourly SVA markets.

The data on these charts is taken from the latest Settlement run for that Settlement Date.

Peaks and troughs in the data may indicate metering systems moving between HH and NHH Settlement or other issues that need to be investigated.

Highlights

This month we have included a GSP Group filter to allow you to explore  the regional differences in numbers of HH and NHH metering systems.  

Microgeneration: Metering Systems and Energy Exported

The chart below shows the number of MPANs associated with microgeneration schemes registered in SVA settlements and the energy in MWh exported by these schemes into the NHH Market.

The data is summed from the number of MPANs associated with Consumption Component Classes (CCC) 32 and 33. These Consumption Component Classes relate to metered NHH Active Export and whether the daily total energy that those MPANs export to the system is from Actual meter reads (CCC 33) or estimated meter reads (CCC 32).

The up and down nature of the settled energy reflects the weekday vs weekend pattern of energy exports. The monthly step changes in the energy volumes reflect changes in the assumed times at which the equipment is exporting.

Highlights

This month we have included a GSP Group filter to allow you to explore in which regions microgeneration sites have been installed.  

Number of Radio Teleswitch Meters

The charts below show the remaining number of Radio Teleswitch Metering Systems and the Suppliers with more than 2,000 Radio Teleswitch Meters remaining.

Radio Teleswitch Meters are able to switch between different tariff rates when a signal is broadcast in radio signals. For some homes the same signal is also used to control heating and hot water.

Suppliers are working to replace these metering systems with smart meters. Elexon is actively monitoring the transition of Radio Teleswitch Meters to Smart Meters as the current arrangements for Radio Teleswitch are due to expire March 2023.

Suppliers in this report are identified by their four letter Market Participant ID (MPID).

Highlights

These graphs on the number of Radio Teleswtich meters have been introduced to monitor the number of Radio Teleswtich Meters remaining. On 9 November 2021 there were 1.17 million radio teleswtich meters remaining in Great Britain. There are 35 Supplier MPIDs with more than 2,000 radio teleswtich meters remaining.
