Interoperability Questions
How did we get here? Why is change needed? What are the interim options? Who could govern the interim?

The existing system can not talk to the meters

With Smart Meters we need the Wide Area Network to talk and listen

The answer - Centralised Comms
“Suppliers will have to use the DCC – a single entity – as that will aid switching and data management. It will control access to the data and secure communications, so it must be independent.”

New investments for Suppliers leading early rollout
• Smart Meters• Head End systems• WAN Comms contracts• Smart Prepayment• All associated IT
![Page 17: Smart Interoperability for Early Rollout - Ben Nicaudie SMi Nov 2010](https://reader033.fdocuments.us/reader033/viewer/2022051820/55389ae0550346b82d8b488b/html5/thumbnails/17.jpg)
New problems for Suppliers leading early rollout
• New concept of “installing supplier”
• Stranded Assets• Negotiating Comms contracts• Dependencies on other Suppliers• Building Market share

Core Principles
1. Impact on the consumer
2. Privacy & Data Security
3. Speed and Cost of Implementation
4. Re-usability
5. Avoiding Scope Creep
6. Existing market arrangements
![Page 21: Smart Interoperability for Early Rollout - Ben Nicaudie SMi Nov 2010](https://reader033.fdocuments.us/reader033/viewer/2022051820/55389ae0550346b82d8b488b/html5/thumbnails/21.jpg)
Interim Options (1)
1. Supplier owned HEs non-standard interfaces to Central Service
2. Supplier owned HEs with standardised interfaces to Central Service
3. Centrally owned HEs providing Central Service
![Page 22: Smart Interoperability for Early Rollout - Ben Nicaudie SMi Nov 2010](https://reader033.fdocuments.us/reader033/viewer/2022051820/55389ae0550346b82d8b488b/html5/thumbnails/22.jpg)
Interim Options (2)
4. Installing Suppliers provide readings to a central store
5. Installing Suppliers provide Smart Meter Services direct to 3rd Parties
6. Suppliers Migrate Smart Meters to gaining Supplier’s HE on CoS
![Page 23: Smart Interoperability for Early Rollout - Ben Nicaudie SMi Nov 2010](https://reader033.fdocuments.us/reader033/viewer/2022051820/55389ae0550346b82d8b488b/html5/thumbnails/23.jpg)
Key Influencing Factors
• Industry has immature Smart Metering infrastructures
• Not all Suppliers have a Smart programme at all
• The industry needs to see interim as a step to DCC

A Roadmap for Interim

How did we get here? Why is change needed?What are the interim options?Who could govern the interim?
![Page 26: Smart Interoperability for Early Rollout - Ben Nicaudie SMi Nov 2010](https://reader033.fdocuments.us/reader033/viewer/2022051820/55389ae0550346b82d8b488b/html5/thumbnails/26.jpg)
The ideal regulatory framework
• A dedicated Smart Energy Code• Governing access to smart electricity
and gas meters• Defining commercial relationships
between DCC and its users • A code common to both gas and
electricity
![Page 27: Smart Interoperability for Early Rollout - Ben Nicaudie SMi Nov 2010](https://reader033.fdocuments.us/reader033/viewer/2022051820/55389ae0550346b82d8b488b/html5/thumbnails/27.jpg)
But this is highly complex...
![Page 28: Smart Interoperability for Early Rollout - Ben Nicaudie SMi Nov 2010](https://reader033.fdocuments.us/reader033/viewer/2022051820/55389ae0550346b82d8b488b/html5/thumbnails/28.jpg)
Existing regulatory frameworks
• The Master Registration Agreement• The Supply Point Administration
Agreement• The Uniform Network Code• The Balancing and Settlement Code• The Data Transfer Services Agreement
![Page 29: Smart Interoperability for Early Rollout - Ben Nicaudie SMi Nov 2010](https://reader033.fdocuments.us/reader033/viewer/2022051820/55389ae0550346b82d8b488b/html5/thumbnails/29.jpg)
Comparing frameworks
• The MRA and SPAA do not provide for data transfers service provision
• The UNC and BSC do cover data transfer but also a much wider area
• The DTSA is solely about metering-related data transfer, associated services and governance
![Page 30: Smart Interoperability for Early Rollout - Ben Nicaudie SMi Nov 2010](https://reader033.fdocuments.us/reader033/viewer/2022051820/55389ae0550346b82d8b488b/html5/thumbnails/30.jpg)
What would be needed?
• A transparent mechanism for cost recovery
• An obligation on gas and electricity Suppliers to join
• No restriction on the use of intellectual property by a future DCC
• Any user objections being ultimately resolved by Ofgem
