CLIENT: Power and Water Corporation
The NT Government established a 10-year strategic plan to enhance infrastructure & development across remote communities, with a strong focus on establishing a comprehensive electrical distribution model. It will enable Power and Water Corporation (PWC) to better understand the existing network capacity at each community.
PWC engaged APD to assist with the development of Power Station Single Line Diagrams (SLDs) for 56 remote communities – the first key stage in a long-term program aimed at improving the local electricity networks.
APD Global is collaborating closely with PWC through three key engineering stages to deliver this work:
1 SLD SKELETON DEVELOPMENT
The stage involves constructing the skeleton of each SLD. Site data collection is coordinated by PWC’s field teams, who visit each remote community power station to capture detailed photos, videos and equipment information, including LV switchboard configurations. APD’s drafting engineers use this data to produce the preliminary SLD drawings for each site.
2 VERIFICATION OF SOURCE INFORMATION & ASSET CONFIRMATION
Senior Engineers from APD are responsible for validating the field data against PWC’s asset database and existing records, ensuring the information shown on each SLD accurately reflects the as-built configuration of the site.
All verified data is consolidated into a single reference document which provides definitive equipment ratings, asset identifiers and traceability of all information used in the drawings.
3 FINALISATION & QUALITY ASSURANCE
APD’s Design Manager oversees the final review and quality assurance process, with detailed cross-checking of all components and annotations, ensuring accuracy and consistency. The deliverables are circulated to PWC for review and feedback. Following endorsement, the final assets are formally published.
CURRENT PROGRESS
Since the commencement of the project earlier this year, APD has successfully completed SLDs for 40 NT remote communities and is on track to deliver all 56, by the end of 2025.
FUTURE OUTLOOK
The next phase involves utilising the completed SLDs to develop detailed electrical distribution models for each community. APD Global will continue its partnership with PWC to provide engineering expertise and support during this stage. It will lay the foundation for
targeted network upgrades and increased reliability of power supply – supporting sustainable
growth and improving quality of life across remote communities.
