Business low voltage kVA transition actual demand tariff The business low voltage transition actual demand tariff is available to business customers reassigned from a business energy tariff to a cost-reflective tariff in July 2015 but who would be worse off as a result. This is a tariff that commences on 1 July 2015. It is part of a suite of tariffs that are required to be used by large business customers. The tariff is a combination of 70% business 2-rate and 30% business actual demand. In 2016/17, the proportion of business will reduce and the actual demand proportion will increase. Transition should be complete by 2020. These customers will require a Type 1-5 NEM compliant meter read at least monthly. All tariff elements used in the business 2-rate and agreed monthly demand tariffs are used in this transition tariff. The low voltage Business actual demand tariff incorporates the charging parameters set out in Table 10. Another variation of this tariff is being created for 2015/16 which has the same structure and demand measurement, but will bill the actual kVA recorded for the number of days between the meter-read dates rather than for a month. This is expected to assist retailers with their billing where type 5 meters are used, as these are read during the month (or quarter) as opposed to the associated with a type 4 meter. The use of a ‘per day’ charge for the maximum demand between read dates was a suggestion received via retailer consultation.

Unmetered supply tariffs Unmetered supply tariffs are applicable to supply points that are not metered. Energy consumption is calculated using the appropriate algorithm in the applicable Metrology Procedure. Unmetered tariffs comprise of an energy rate that is applied to the calculated electricity consumption. There are two unmetered supply tariffs that are assigned by SA Power Networks, depending upon the customer’s consumption profile: Unmetered Overnight Usage supply is for overnight use for public lighting. Unmetered 24 hour usage supply is for constant 24 hour per day use, typically public phones, traffic lights and telecommunications installations. The low voltage unmetered usage tariffs incorporate the charging parameters set out in Table 13. 13 - Unmetered overnight and 24 hour usage tariff charging parameters Charging Parameter Units Element of service Direct control Transmission recovery Jurisdictional Scheme Amount Pass Through Alternative control Description DUoS TUoS Metering Anytime Usage Rate $/kWh X X X - For estimated energy consumption Unmetered supply tariffs are generally invoiced monthly.
