1 Introduction
This register of completed embedded generation projects has been developed to improve the level of technical information available, on projects that have been successfully connected to Energex’s distribution network.
2 Purpose of this Register
Under Chapters 5 and 5A of the National Electricity Rules, Energex is required to publish a register of completed embedded generation projects. This register:
• includes details of all embedded generation projects (i.e. for systems with a generation capacity of 200 kW or greater) completed within the preceding five year period; and
• Update annually for all completed projects in the 5 year period preceding the review date.
3 Details included in the Register
A register of the plant of completed embedded generation projects includes, but is not limited to:
• technology of generating unit (e.g. synchronous generating unit, induction generator, photovoltaic array, etc) and it’s make and model;
• maximum power generation capacity of all embedded generating units comprised in the relevant generating system;
• contribution to fault levels;
• the size and rating of the relevant transformer;
• a single line diagram of the connection arrangement;
• protection systems and communication systems;
• voltage control and reactive power capability; and
• details specific to the location of a facility connected to the network that are relevant to any of the details in the bullet points above.

7 Protection Schemes and Requirements
Level 1 Backup Protection • Over and under voltage
• Over and under frequency
• Voltage vector shift and
• Rate of change of frequency
• Reverse Power
Level 2 Backup Protection • Neutral voltage detection/unbalance, or
• Direct intertrip from network circuit breaker (for systems above 200kW).

8 PQ Voltage and Power Factor Control
New connection standards have been published. Any new connections must adhere to the requirements under the STNW1174, Standard for the Connection of Embedded Generating Systems to a Distributor’s LV Network, or STNW1175, Standard for the Connection of Embedded Generating Systems to a Distributor’s HV Network, as relevant. For low voltage customers, pursuant to clause 36(2)(d) of the Electricity Regulation, Energex requires the Customer to ensure that the inverter operates in the volt-var requirements of STNW1174. This standard can be found on the Energex website, via Connections > Major Business Connections > Large Generation and Batteries. For high voltage customers, the power factor is to reflect the agreed voltage or power factor control arrangement. Please note connections must comply with the requirements set out in STNW1175, which can be found on the Energex website, via Connections > Major Business Connections > Large Generation and Batteries.
