Service Main Voltage Rise Criteria

What is happening?

Essential Energy is committed to providing customers who wish to install low-voltage embedded generation access to the network where it does not compromise quality, safety and reliability of supply to other network users.

To facilitate this, we have revised our assessment criteria for connection of embedded generators to the low-voltage network.

Effective Monday 15 June 2020 our revised criteria requires that voltage rise on Service Mains is maintained within 1% (in accordance with clauses '1.12.3.4' & '8.6.13' of the NSW Service Installation Rules). This will enable Essential Energy to maintain voltage at the point of connection at 253V.

Exemptions

Application of exemption clause '8.6.13.1' will not be accepted when it results in an increase of voltage on the Service Mains greater than 1%. We will consider exemption where combined voltage in the Consumer Mains and Sub Mains is limited to 2% (as per clause '3.3.3' of AS/NZS4777.1-2016).

Alternative compliance mechanisms may include applicants proposing Service Mains augmentation or imposing export limits to their generator systems in order to maintain the voltage rise within the Service Mains to 1% (as per clause '8.6.3' of the NSW Service Installation Rules, and noting that export limits will not impose a limit on the capacity of generator systems for self-consumption).

At this time, the standing automatic approval for energy export of 5kW per connection point for urban, and 3kW per connection point for rural customers remains in place.
