MP085 Synchronisation of smart meter voltage measurement periods

Proposer Alan Creighton
Lead Analyst Bradley Baker
Date raised 12/09/2019
StageRefinement Process
Implementation date Unknown
Latest update SECAS will liaise with the Proposer and the DCC to further refine the Proposed Solution.

What is the issue?

The expectation of Electricity Network Parties during the development of the smart meter technical specification was that the average RMS voltage readings from smart meters would be measured across a consistent period. For example with the default being for an average to be made across a 30 minute period starting on the hour and again on the half hour. This is not an explicit requirement codified in Smart Metering Equipment Technical Specifications (SMETS) or Great Britain Companion Specification (GBCS).

Without voltage measurements being made in a consistent way, Electricity Network Parties must either i) make conservative, less efficient analysis assumptions to account for the lack of data alignment or ii) recreate synchronised data by downloading high granularity (for example minute resolution) data and calculating the required data.
