Maximising Utility Asset Lifespan: Why Spare Parts and Field Logistics are key.

What is legacy infrastructure in utilities and why does extending its life matter?  

For utilities across Australia, ageing networks of transformers, switchgear, pipelines, and substations still form the backbone of critical service delivery. Replacing these assets is expensive, time-consuming, and often disruptive. That's why service teams are under increasing pressure to do more with what they have, through strong Proactive Maintenance and Rapid Reactive Maintenance to keep legacy infrastructure running safely, reliably, and cost-effectively for as long as possible.

But here's the catch: keeping legacy assets online requires more than just reactive maintenance. It demands visibility over spare parts, timely resolutions, and logistics models designed for uptime. That’s where Droppoint comes in.

We help utility providers extend asset life by transforming how parts move through the field. With our inventory-first approach, service teams can access the right part, in the right place, at the right time boosting uptime, hitting SLAs, and avoiding unnecessary asset replacements.

Why Legacy Infrastructure Still Matters

Across Australia and New Zealand, utility providers are operating infrastructure that has far outlived its original design life and that’s something worth celebrating. We’re seeing large-scale hydro plants still delivering power after 70+ year¹, nuclear assets running for 55+ years²  and coal-fired stations at around 30 years³. Even in the renewable space, we’re seeing wind and solar assets surpassing 20 years⁴, and batteries still performing after 15+ years⁵. That kind of longevity doesn’t happen by accident, it’s the result of decades of careful planning, skilled engineering, and frontline teams making it work, day in and day out.

But as much as these are incredible achievements, they also bring new pressures.

Major capital upgrades are often delayed or rolled out in stages due to budget constraints, shifting regulatory requirements, or evolving energy targets. In the meantime, legacy assets remain critical to the grid, and their ongoing performance has become a frontline issue for service teams.

The risk? As these assets age, the likelihood of failure increases, along with the consequences: unexpected outages, safety incidents, missed SLAs, and declining public trust.

Supporting them isn’t easy either. These older systems often rely on obsolete or difficult-to-source spare parts, lack digital models or twins, and require manual workarounds that eat into technician time. And all too often, field service teams are expected to hold the line - without the parts visibility, real-time inventory data, or logistics support needed to respond efficiently.

The Hidden Costs of Managing Legacy Infrastructure

It’s not just about asset age, it’s about what it takes to support them in the field. As a business that has supported field service teams across wide geographies, we’ve seen the ripple effect that poor parts visibility and slow logistics have:

• Downtime drags when the required spare part isn’t available on-site or even in the depot.

• Preventative maintenance plans stall because teams spend more time chasing parts than executing scheduled works.

• Technicians are underutilised, burning time waiting or making return visits due to incorrect stock.

• SLAs are missed, not because the team can’t do the work, but because the system behind them isn't working.

These operational blind spots are costly. They show up in asset reliability reports, missed uptime targets, and emergency call-outs that could have been avoided with smarter planning.

Smarter Field Logistics: The Key to Legacy Uptime

At Droppoint, we believe extending the life of legacy infrastructure isn’t just a maintenance problem it’s a logistics and inventory management challenge.

Here’s how we help utility teams close the gap between planning and execution:

1. Spare Parts Where and When You Need Them

Legacy assets often require low-volume, high-impact components. Our pre-positioning model ensures those niche parts are available closer to where your team starts their day leading to reduced down-time & reduced inventory sitting idle.

2. Inventory Visibility Across the Field

Our platform gives you real-time insight into what parts are in vans, depots, and field lockers, so you know what’s consumed, what’s needed, and where gaps might appear. This supports smarter scheduling and fewer failed jobs.

3. Preventative Maintenance That Sticks

We align logistics with your preventative maintenance plans. No more rescheduling due to unavailable parts. With Droppoint, you can execute your maintenance strategy on time, every time, reducing emergency failures and extending asset life.

4. Rapid Response for Unplanned Events

When something does go wrong, our agile logistics model ensures urgent parts can be delivered quickly, even in remote locations. Faster responses, reduced outage windows, and better customer outcomes.

Field-First Design: Built for How You Actually Work

The gap between the control room and the field has never been wider. We’ve seen techs show up to substations with outdated part data or wait half a shift for deliveries that were misrouted. Our logistics model and our fit for purpose Materials Orchestration Software (MOS) is built to bridge that.

• We integrate with your existing ERP systems - no need to rip and replace.

• We help automate van stock replenishment and usage tracking.

• We design around the reality of field service, not the ideal.

And with technician productivity and asset uptime becoming key metrics in regulatory performance reviews, it’s never been more critical to get logistics right.

Real Results: Better SLAs, Longer Asset Life

Droppoint clients in the utility sector have:

• Added 2-3 extra technician jobs per week

• Improved scanning compliance by +10%

• Reduced inventory holding by 30%

Extend the operational life of ageing infrastructure by avoiding unnecessary downtime all by taking control of your spare parts and logistics.
