Reactive Power Control Requirements - 30 September 2015 
 

The joint Energex and Ergon Energy Connection Standard for Small Scale Parallel Inverter Energy Systems up to 30kVA came into effect from 1 July 2014, however the Reactive Power Control was deferred.

Commencing 30 September 2015, automatic approval will only be given for fixed power factor inverters rated at 3kVA or less, or for reactive power factor inverters rated higher than 3kVA with the power factor set at 0.9 lagging. (where these inverters are exporting to the grid)   A confirmation check box will added to Electrical Partners Portal acknowledging this requirement.

Proposed Changes to Approval Limits
 

As a result of the pending changes to power factor control for inverters greater than 3kVA, Energex are proposing an increase in the approval limit for full export for three phase inverters up to 15kVA. These balanced three phase systems have a similar effect in terms of local voltage rise as a single phase 3kVA system. The inverters are required to be a true three phase inverter (not three x single phase inverters) with reactive power control set at 0.9 lagging, on a three phase network. An infographic showing the proposed changes is below.

Seeking your feedback on Connection Standard >30kVA
 

Energex and Ergon Energy consulted with industry and peak bodies in 2014 to successfully develop the current Connection Standard for Small Scale Parallel Inverter Energy Systems up to 30kVA.

We are now seeking further feedback on the Standard to provide input to an updated version before its planned release in January 2016.  We encourage you to submit your ideas and suggestions via email to This email address is being protected from spambots. You need JavaScript enabled to view it. between now and midnight Sunday 20 September 2015. The existing Connection Standard can be found on our website

Following consideration of all feedback, an updated draft Standard will be released for further industry consultation around November 2015.
 


 

Technical Updates

Removing Control Load metering when installing solar 
 

If a customer advises that they no longer require their existing Off-Peak Control Load metering, and request the removal of the associated meter and equipment, it is important that Energex is notified in the 'Additional Information' section of the Electrical Work Request (EWR) of your solar install job.  Failure to notify Energex will result in the customer continuing to receive network charges for the Control Load Tariff.
 

Requests for Dual Element Meters


The standard metering arrangement is for a single element meter for the primary tariff, and a second single element meter with separate relay for any control load tariff that may exist at the premise.

If you are seeking approval for a dual element meter due to space limitations, this request must also be noted on the EWR in the 'Additional Information' section.  If the property has been wired for this meter type and there has not been a request for a dual element meter on the EWR, the job will be issued with a Form 3. 
 

Metering Panel Changes


The addition of a solar PV inverter energy system may require alteration to customer’s metering installation, under clause 7.7.2 of the Queensland Electricity Connections and Metering Manual (QECMM).
 
Electrical Additions & Alterations (Minor) - Where minor upgrades are carried out to a customer installation (e.g. additional tariff or IES metering, load centre change, replacement of a meter panel within an enclosure where the enclosure is not being replaced) the meters may be left in the existing location, provided the metering location is suitable to the metering provider (refer to Clause 7.7.3 for unsuitable locations).

Installers should refer to the QECMM for unsuitable locations and where required, upgrade or relocate the metering panel.  If a location is deemed unsuitable, a Form 3 will be issued by Energex.
