Crowded Meter Rooms
How does it work?
The first stage in making a Crowded Meter Room “smart ready” is to undertake a site survey. The Alt HAN Co CMR team work in partnership with two Meter Equipment Managers (MEMs); IMServ and SMS Energy. Our partners will visit buildings where industry data has shown that there may be not enough room in the meter rooms for the successful installation of an Alt HAN range extending device which may be required.
Once a site survey has been completed and it has been established that there is not enough space to install an Alt HAN device, a design proposal is created. Each meter room has different challenges to make it “smart ready”; the design proposal for each site enables Energy Suppliers to have enough space to install an Alt HAN device on the meters, allowing their customers to have a working In-Home Display, as and when they chose to request one from their Energy Supplier.
After gaining agreement from the Building Operator, work will then start in the meter room, with costs being met by the Energy Suppliers. The MEMs will write to all affected residents of the building, informing them of the work and when it is taking place. As the electrical supply needs to be disconnected for a short amount of time whilst these works are undertaken, information is provided to residents on how to let us know if they are unable to have their power turned off for any reason. Typically, works take one day and all efforts are made to minimise the impact on residents of the building.
Once the works are completed, the relevant Energy Suppliers are contacted to inform them that the meter room is now “smart ready”, and they will then contact their customers to offer them a smart meter installation.
Report a Crowded Meter Room
We would like Energy Suppliers to regularly submit any data (aborted information is a particular interest for the project) that they believe could hold a problem to completing a smart installation.
A Crowded Meter Room (CMR) is where a space containing co-located meters has technical or physical constraints that would prevent the installation of smart metering equipment. The Alt HAN device and the connector Block, adds to the foot-print of a metering system (see picture on the right). A bridge 1 will always be needed where an IHD or gas meter is not able to directly communicate with the Comms Hub. Specific consideration to the DCC & Alt HAN installation guidelines should be assessed when reviewing if an aborted visit is a CMR
Common CMR Challenges:
- No space between the meters or within the location
- Trunking
- Significant Metallic Object obstruction
- Landlord or Network Owner equipment.
- Suppliers’ equipment or metering limiting space in a meter room (e.g. isolation switches)
- Insufficient cable length going into the multi service distribution board
- Looped neutral set ups (including auxiliary)
- Radio Tele Switch meters (including communal)
- Any other challenges that require coordinated activity.
