UNCLASSIFIED OPERATIONAL PROCEDURE – Connection Guidelines for High Voltage Connections and Embedded Generators CEOP8079 The results achieved from the test. Each test report must be: Signed and dated by the testing officer(s) and the witnessing officer Provided to Essential Energy. 12.3.4 Commissioning Tests The Connection Applicant will produce a test plan to cover the commissioning requirements of all High Voltage assets and secondary equipment. This plan must identify testing responsibilities and actions for all parties and must be submitted for Essential Energy‟s agreement and approval. Essential energy must approve the commissioning program, final design and equipment requirements, prior to it being finalised by the Connection Applicant‟s ASP or its nominated representative. Commissioning tests will vary depending upon the type and make of equipment to be installed, the manufacturer‟s recommendations and Essential Energy‟s policies covering commissioning tests for zone substation equipment, secondary systems, HV transmission lines and cables. Final commissioning may also require phase identification, temporary protection schemes, service voltage testing, phasing out checks, protection directional checks and in-service balances and in-service metering checks. Essential Energy needs to ensure that all appropriate tests have been completed so that all HV equipment can be energised. This will require close cooperation between the ASP and Essential Energy employees. Essential Energy will also expect the Connection Applicant to rectify all defects found as a result of testing and checks by Essential Energy or others employed by the Connection Applicant. Any delay in defect rectification may impact on final commissioning which may, in turn, delay commissioning of other infrastructure owned by the Connection Applicant. Commissioning tests and checks to ensure compliance may include but not be limited to: Substations General compliance including civil and building works, secondary containment systems, fencing, public safety, security, fire protection systems, general layout of equipment Identification of equipment in accordance with Essential Energy‟s requirements Earth grid and earthing of equipment Conductivity and insulation testing HV disconnect and earthing switches HV circuit breakers HV current transformers HV voltage transformers Power transformers (including high voltage testing and On Load Tap Changer (OLTC) Protection schemes and associated secondary equipment Substation control systems Metering SCADA systems 23 November 2012 - Issue 7 Approved By: Group Manager Major Customer Engagement Page 24 of 36 UNCLASSIFIED UNCONTROLLED COPY IF PRINTED

Any discrepancies will need to be rectified by the Connection Applicant. Only after Essential Energy‟s acceptance tests have been completed will the asset be allowed to be energised. 12.4 Handover and Defects Liability Period "Handover" of the electricity works from the Connection Applicant to Essential Energy will occur on practical completion (as that term is defined in the relevant contract). The defects liability period will commence on the date of practical completion and will end on the expiration of the period specified in the contract after the date of practical completion (or if there a several such periods, for example where there are separable portions, the last to expire). During the defects liability period, Essential Energy may direct the Connection Applicant to rectify any defects in the electricity works. The contract may allow Essential Energy to direct the time within which the Connection Applicant must commence and complete the rectification of defect. Essential Energy may also set a further defects liability period in respect of work rectified - that period being effective from the date of rectification for a period specified by Essential Energy. While security held by Essential Energy is usually reduced upon practical completion, the remainder of the security should be held until the later of the issue of the final certificate under the contract (which occurs after the expiry of the defects liability period) and date on which all defects identified during the defects liability period have been rectified. 13 HV ASSETS TO BE OWNED AND OPERATED BY OTHERS In addition to the requirements listed under Section 11, of these Guidelines the following requirements must be complied with for all assets to be owned and operated by others. 13.1 Design, Equipment and Materials All design details must be endorsed by a Level 3 ASP to meet the requirements of AS/NZS 3000 Australia/New Zealand Wiring Rules, the NSW S & I Rules and AS/NZS 7000:2010 Overhead line design – Detailed procedures. 13.2 Design References 13.2.1 Transmission, Zone and Switching Stations HV assets must meet the requirements of AS/NZS 3000 Australian/New Zealand Wiring Rules, and the NSW S & I Rules. 23 November 2012 - Issue 7 Approved By: Group Manager Major Customer Engagement Page 25 of 36 UNCLASSIFIED UNCONTROLLED COPY IF PRINTED
