OVERVIEW

In 2019 we implemented phase one of our Enterprise Resource Planning System (ERP) – our new business platform. (you can read more about this here).

ERP relies on accurate data about the assets we have on our network – what they are, what condition they’re in and how they’re performing. Moving to ERP from our old systems was an opportunity to review and tidy this information, and to fill any gaps.

To do this we’ve been working on things like:

  • Implementing new software and processes to continually monitor the quality of data going into our systems
  • Collecting and entering missing data about our assets (see some of our figures below)
  • Establishing more formal review and data auditing processes for project closures

As you can imagine, this work has required collecting and updating a lot information. Here are some figures on the data we’ve tidied up:

  • Removed more than 20,000 unnecessary defect notification records (such as duplications, errors, or issues that were no longer relevant).
  • Added unique identification numbers to approximately 5,000 of our low voltage boxes
  • Updated our location descriptions to include a full description of an asset for about 2,000 network devices
  • Added work order references to over 2,000 assets so work history can be traced.
  • Added 408 missing site identification numbers for our roadside switching cabinets
  • Added 80 low voltage boxes missing from the system

 

Powerco has worked on a number of smaller data quality initiatives over FY20.

We’ve verified core data about some of our most important and valuable assets – our Power Transformers and overhead lines, to ensure we had the correct information in our systems. Updated functional location descriptions to include full physical identification for around 2000 network devices.  Providing benefits to service providers efficiency and safety, network reliability, asset management effectiveness in being able to positively identify devices in the field. We even got our summer interns to help us improve out asset data quality.

By improving the data quality of our assets, defects and inspections means we can be more efficient in the way manage the network and keep your lights on. As a result of our data cleansing efforts we carried out during the first year of CPP, we’ve been able to prioritise our critical defects and focus to fix the reducing our defects backlog. During CPP- year two, we have fixed  over 13,000 defects across our network, which is  nearly 50% of our start backlog defect backlog, this means a safer and more reliable network for you.

To provide ongoing support to these efforts we’re working on improving our data standards and our data governance framework. Our Asset Information Strategy is now in place and we’re making progress towards the data standards we need to achieve ISO55001 certification. (which you can more read about here)

The challenge
Ensure we have accurate data about our assets across our network to inform our planning and maintenance.

The solution
Cleanse our existing data and ensure we have the right systems and processes in place so that comprehensive and accurate data is being entered into the system moving forward.

The benefit
Having accurate data about our assets allows us to work efficiently and make well-informed decisions about what we work on.

Milestones

Construct new substation building

The first part of the South Waikato Grid Connection project is to replace the building - which doesn’t meet earthquake resilience standards - and upgrade the equipment at the Putaruru substation.

Route for new circuit between Arapuni and Putaruru confirmed

FAQ

We strive to minimise impact in the design and placement of network infrastructure and we’re still planning and consulting on the route for the new circuit. The circuit will be a mix of overhead lines – which you will see, and underground cable – which you won’t see. You’ll also see a new building at our Putaruru substation, replacing the ageing existing building there.

We can never guarantee supply 100% of the time, however, the number and length of outages you experience will be reduced.
