The majority of meters in use in domestic premises here are still electromechanical. ESB has only started to go digital in recent years. Dual tariff meters (day and night rate) seemed to be the first to switch over.
Larger commercial 3-phase supplies have much more complicated metering and tariff arrangements, so there has been digital metering, sometimes with automatic reporting, for quite some time now.
The models and makes of digital meters being used in residential seems to vary, but they have a standard reading port which a meter reader can access via a hand-held device.
The other major manufacturer seems to be Siemens.
The service fuses in Ireland vary depending on the age of the installation too. Some installations have a diazed (bottle-shape) fuse in a clear plastic enclosure which is sealed with the usual warning labels and seals.
The most modern installations have a rotary switch directly after the meter, this allows the electrical contractor to self-certify and energise. They then apply coded seal to the isolator switch.
In all installations here, the customer's panel must also contain a 'main switch' to isolate the entire system and a 'main fuse', (usually a neozed switch-fuse thesedays, which looks rather like an MCB module.). Certain approved MCBs are now allowed for this purpose too.
The idea is that if the panel is overloaded, the customer's main fuse will blow faster than the service fuse, thus avoiding the need for service calls to the power company.
The service fuse would only blow in very unusual circumstances i.e. where someone has tampered with the customer's main fuse.
Smart Metering's being rolled out to a selection of homes here at the moment using meters made by Sagem (France).
They either backhaul the data over the powerlines, or in some areas where this isn't possible they have a GSM data module and SIM card inside and send / receive data through the mobile phone system.
Customers are receiving their normal power bills, with their usual tariffs and a 'Shadow Bill' which is based on their smart-meter readings.
