Equipment interventions

Gas distribution network operators are required to respond to “smell of gas” calls. During their investigations on site gas distribution network operators may discover a recent smart meter install has resulted in a gas escape or an unsafe situation. Gas distribution network operators immediately make these situations safe and compile the details of these incidents to bring to the attention of the suppliers, Meter Operators and parties responsible for managing, mentoring and training meter installers.

• ENA GER4 Issue 3 identifies the five most common failure modes that lead to a gas distribution network operator intervention visit following a gas meter exchange.
• Gas Meter Installers can watch the sequence for gas meter exchange video below for background on gas escapes and correct installation methods and procedures.

The types of equipment issues encountered by a meter installer and the necessary remedial action are described in the following guidance for reporting service termination issues:

A guide for gas meter operatives on reporting and acting on asset condition issues (ENA GER1 Issue 9.1)

ENA GER1 Issue 9.1 (available in our Resource library) helps smart meter installers to identify, categorise and report any network related issues.

Guidance for correct reporting of exposed PE pipe (ENA GER5 Issue 1)

ENA GER5 Issue 1 (available in our Resource library) helps gas smart meter installers correctly report circumstances of exposed PE pipe to the relevant network operator.

Gas engineering recommendation GER2 issue 2

GER2 Issue 2 (available in our Resource library) clarifies gas distribution network operator responsibilities regarding business as usual processes affected by the introduction of smart meters and to minimise inconvenience to the network customer.

Electricity distribution network operators and gas distribution network operators have produced the following information for energy suppliers to assist with newly installed smart meters during or prior to commissioning.

Standard electricity network operator electricity smart meter configurations (ENA EREC M30 Issue 2)

ENA EREC M30 Issue 2 (available in our Resource library) specifies a set of standard configurations relating to Electricity Network Operator functionality that should be applied to an electricity smart meter prior to commissioning. It is anticipated that these settings will be applied as part of the manufacturing or testing process by the smart meter manufacturer. The electricity network operator can change these settings post commissioning using the appropriate DCC Service Request.

This issue clarifies the requirement to send an alert at the point in time when an event condition is no longer present and incorporates the changes associated with revisions to Smart Metering Equipment Technical Specifications (SMETS) and the GB Companion Specification (GBCS).

DNO strategy for supplier population of network operators’ trust anchor cells in electricity smart meters (ENA EREC M31 Issue 1)

This strategy provides guidance to suppliers on the appropriate use of DNO and iDNO credentials in accordance with Inventory, Enrolment and Withdrawal Procedures set out in the Smart Energy Code.

Suppliers need the correct DNO/iDNO credentials given in this document in order to populate the network operator trust anchor cells in a newly installed electricity smart meter.

The EREC M31 is available to all supplier parties via the SEC Party section of the SEC website. Parties wishing to gain access to this webpage will need to be a SEC Party and have a SEC Website User Account. Contact the SECAS Helpdesk to request access to the ID Allocation webpage.

Guidance for Using Correct Organisation Certificate in the Gas Network Operator Trust Anchor Cells (ENA GER3 Issue 1)

This guide assists with the selection of the correct Organisation Certificates that should be used in the Network Operator Trust Anchor Cells on the Gas Proxy Function, when installing and commissioning a Smart Meter.
