MP075 Third party metering service providers

Proposer Steve Mulinganie
Lead Analyst Jordan Crase
Date raised 30/04/2019
Implementation date Unknown
Latest update This Modification Proposal was Withdrawn on 14 August 2019. Comments from the Proposer were that the Agreed Interpretations V1.8 update sufficiently captured the intent of this Modification Proposal.

What is the issue?

At present there is no recognition within the SEC of Suppliers relationships with Meter Asset Managers (MAM) and Meter Asset Providers (MAP). In SEC Section G, under ‘Manufacturers: Duty to Notify and Be Notified’, if a User identifies a security vulnerability in a Smart Metering System that they are the Responsible Supplier for, they shall notify the manufacturer of the device, rectify or mitigate the vulnerability, and report the vulnerability and steps taken to the Security Sub-Committee (G3.17 & G3.18). Reporting of security vulnerabilities to the Security Sub-Committee is also outlined in SEC Section G3.9. The Responsible Supplier for a Smart Metering System shall also make arrangements with the Device Manufacturer to be notified of security vulnerabilities that the manufacturer identifies (G3.20).

In many cases for non-domestic suppliers, there is no formal relationship between the Supplier and the MAP, or the Supplier and the manufacturer, as is assumed in the duty to notify guidance. In such cases the Supplier may have a formal contract with a MAM, or with the end consumer who may have specified certain requirements.
