1. Demand Estimation - Non Loggable Meters: Issue
For the purposes of Demand Estimation – NDM algorithm profiling
A sample of NDM meter points across all consumption bandings have data recording equipment installed (recorders & loggers)
Sample counts need to be maintained to ensure accurate NDM profiling algorithms
Identifying an increasing number of non-loggable meter installations:
Meters with no ‘pulse’ connection
Cheaper to purchase than loggable meters
Data recording equipment cannot be installed on these sites

2. Demand Estimation - Non Loggable Meters: Impacts
Meter replacement programmes are favouring non-loggable meters
Age analysis suggests 50% of the current NDM sample will require meter replacements in 5 years
Installation of replacement non loggable meters will result in the recording equipment being removed
Sample sites are continuing to be terminated
Replacement / new sample meter points will become increasingly difficult to identify
Larger consumption bandings may be significantly affected
