Metering requirements
The following links provide the electrical consulting and electrical contracting industries information regarding all requirements for any connection, of all types of installations, to a Horizon Power Network.
Mandatory Link Criteria and Metrology Procedure
Horizon Power has received approval from the Economic Regulation Authority for the mandatory link criteria under Part 6 of the Electricity Metering Code.
The mandatory link criteria deals with the communication links required by metering installations so as to enable meters to be read from remote locations via telecommunication networks.
The following documents explain the Horizon Power's Mandatory Link criteria, Metrology Procedure for Meter Installations and the approval received from the Economic Regulation Authority.
