SECMP0015 GPF timestamp for reading instantaneous Gas values

Proposer Tim Larcher
Lead Analyst SEC Change
Date raised 31/05/2016
StageImplemented
Implementation date November 2022 SEC Release
Latest update This modification was implemented on 3 November 2022 as part of the November 2022 SEC Release.

What is the issue?

Instantaneous Gas Smart Metering Equipment (GSME) register values can be read from the Gas Proxy Function (GPF). These will not normally be in-line with the readings on the GSME, since the GSME only provides intermittent updates to the GPF, typically once every 30 minutes. Without a timestamp to know when the GSME last updated the GPF, the Supplier cannot know how up to date the information is.

What is the solution?

The Proposed Solution is to allow Parties and devices reading the instantaneous values from the GPF to know the time on the GSME's clock when the value was provided. This will also allow In Home Displays (IHDs) and Pre-Payment Interface Devices (PPMIDs) to determine and display the time of the last updates.
