Cyclone Seroja update
The revenue meter is required to be changed or reconfigured to measure bi-directional energy flows (import – export meter registers) before the connection of the embedded generation system. Please contact your electricity retailer before applying to Western Power for technical approval of your proposed system.
If a sub-meter is associated with the connection point at which bi-directional flows will occur, you may wish to engage a licensed electrical contractor to change the sub-meter and make the necessary arrangements with you at the revenue meter.
If bi-directional flows will occur at a sub-meter the measurement of energy flows is at the discretion of the customer. You may wish to engage an electrical consultant or contractor for energy management options.
