Volume 7 Issue 1 - 12 February 2015

New IES connection standard – implementation date for mandatory Reactive Power Control

30 September 2015 - date for full implementation of Standard 1143 - IES systems between 3 and 30kVA


On 16 December 2014, Installer Alert Volume 6 Issue 4 outlined our proposal to implement the reactive power control (RPC) requirement from 1 March 2015 as part of the combined Energex and Ergon Energy Connection Standard for Small Scale Parallel Inverter Energy Systems (IES) up to 30kVA.

Energex and Ergon Energy have reviewed this date following receipt of submissions from companies using micro-inverters who requested more time to source a compliant product.  The decision has been made to defer this requirement to have RPC enabled at 0.9 lagging from being made mandatory on all export systems greater than 3kVA to 30 September 2015.

Deferring the requirement for the introduction of RPC for smaller grid-connected generators will provide additional time for the upcoming revision to Australian Standard AS4777 to take effect.  It will also provide additional time to allowing for installers to clear stocks of non-compliant inverters, and necessary updates to our Electrical Partners Portal

Together with Ergon Energy, Energex reaffirms our commitment to ensure customers have the ability to install IES systems to offset their existing load and absorb excess generation back into the network.  The proposed RPC requirement is in line with measures being taken in Germany and other parts of Europe where IES penetration is high.

Whilst the RPC requirement is not mandatory until 30 September 2015, we would encourage all installers who are ready to start installing equipment with the RPC enabled at 0.9 lagging to reduce the probability of over-voltages occurring on the network.  This will reduce nuisance tripping of the systems, as well as interference to other customers.
