For example, contracts and costestimates, affected by EPA and planning issues for extensions or augmentations. Early consultations with your DNSPabout EPA processes may help to avoid delays at Step 3.CHECKLIST - Step 3: Application to connectAt Step 3 you should have:• Selected an appropriate generator and model.• Applied for connection with your DNSP.• Negotiated any augmentations (including the cost) with your DNSP.• Negotiate technical and commercial terms and conditions.• Received an offer to connect from your DNSP.22 - Guide to Connecting a Distributed Generator in Victoria
Step 4: Connection agreement and generator installationAt Step 4 you will form a legally binding connection agreement. You will need to accept the offer to connect fromthe DNSP, along with the negotiated terms and conditions of the connection agreement.It is advisable to finalise the connection agreement before commencing the construction and installation of the generator.CHECKLIST - Step 4: Connection agreement and generator installationAfter Step 4 you should have:• Accepted your DNSP’s offer• Signed off the connection agreement between you and your DNSP• Completed installation of your generator and network extensions / augmentationStep 5: Inspection and commissioningOnce the generator has been installed, the site and all works will need to be inspected and tested before live connectionto the network.ESV will conduct the inspection and may request alterations if required. They will issue a Certificate of Electrical Safety.Following the inspection, a range of connection tests will be performed in the presence of a DNSP representative.Live connection to the network will then take place.After connection, the generating plant will be tested and commissioned by the installation engineer to ensure the plant isready for regular service.CHECKLIST - Step 5: Inspection and commissioningAfter Step 5 you should have:• Arranged and completed an inspection of the electrical works by ESV• Successfully tested the system connection in the presence of your DNSP• Achieved live connection• Undertaken and completed commissioning5.3 Connection process flowchart and checklistThe connection process and interactions with a DNSP are illustrated in the connection process flowchart and checklist(Figure 4). The DNSP processes used have been adapted from CitiPower / Powercor Guidelines (Appendix 5).These guidelines may not be applicable to all Victorian DNSPs.Steps 1 to 5 are presented in a single connection checklist template (Figure 5) so you can track your progress.Adapt the template to suit your DNSP processes.You are strongly advised to document every step of the project and negotiations with your DNSP.This should include generation issues, connection arrangements and protection settings.Guide to Connecting a Distributed Generator in Victoria - 23
