Stop Replacing Assets Too Late.
Or Too Early.
European DSOs and water utilities manage infrastructure valued at over EUR 1.5 trillion, much of it installed during the post-war electrification and urbanisation programmes of the 1950s through 1970s. EURELECTRIC estimates that 40% of distribution transformers across Europe exceed 30 years of service. EurEau reports that 23% of European water mains are over 50 years old, with leakage rates averaging 24% across the EU-27. Marcogaz data shows EUR 200+ billion in legacy cast iron and grey steel pipe replacement obligations. Replacing everything is financially impossible under regulated tariff structures , but every unplanned failure accumulates the CI/CML, SAIDI, or END minutes that your national regulatory authority uses to set performance-based incentive penalties. Argus reads the story written in every asset's sensor data, maintenance records, and environmental exposure to predict failures before they happen and extend asset life where it is safe to do so , targeting the 5% of assets that cause 40% of your unplanned interruptions.
The right maintenance at the right time. Not too early (wasting 15-25% of remaining asset life), not too late (causing preventable outages). ISO 55001-aligned asset decisions that reduce costs, prevent failures, and are defensible in your next regulatory price control review.
Every Asset. Every Utility Type. One Registry.
From a 400 MVA power transformer at a transmission substation to a 50 mm PE gas service pipe beneath a residential footpath , Argus maintains a living registry of every asset in your infrastructure with real-time health data, full maintenance history, and failure probability forecasting. No more siloed databases where your electricity asset data lives in GIS, your water asset data lives in CMMS, and your gas pipeline data lives in a separate integrity management system. One registry. One truth. One place to answer the question: which assets need attention today? Built from our Dublin headquarters with full GDPR-compliant data sovereignty , your asset data remains within your designated EU data centre region.
A Health Score for Every Asset. A Reason Behind Every Number.
Every asset receives a continuously updated health score from 0 to 100. But a black-box number is worse than useless , it erodes trust when engineers cannot validate why a brand-new recloser scored 72 or why a 40-year-old transformer scored 68. Argus explains every score: which factors are driving it down (accelerating DGA trend, overdue maintenance, environmental exposure), which factors are holding it up (recent refurbishment, below-rated loading), and what specific action will have the greatest impact on improving the score. Your asset managers get defensible, transparent health assessments they can present to national regulatory authorities during price control reviews , not opaque AI predictions they cannot explain to Ofgem, CRE, BNetzA, or ARERA commissioners. Fully aligned with ISO 55001 asset management principles, EN 13306:2017 maintenance classification, and EN 15341 maintenance KPIs.
Health Score
Recommended Action
Replace
0-25Asset has reached end of economic useful life , repair cost exceeds 60% of replacement cost, or failure would cause unacceptable safety/reliability consequences. CAPEX allocation recommended for next regulatory period submission.
Refurbish
26-40Major maintenance or component replacement (e.g., transformer re-winding, pump impeller replacement, valve actuator overhaul) can extend asset life by 10-20 years at 30-50% of replacement cost. Classified as condition-based maintenance per EN 13306:2017.
Repair
41-60Specific component repair addresses the identified deficiency , oil leak repair, gasket replacement, bearing replacement, cathodic protection rectifier repair. Targeted intervention that restores health score by 15-25 points. Classified as corrective maintenance per EN 13306:2017.
Monitor
61-100Asset is healthy and performing within specifications. Continue routine inspection schedule per EN 13306 predetermined maintenance intervals. Do not spend regulated OPEX on assets that do not need intervention , redirect resources to the critical and poor categories.
Score Contributing Factors
Age relative to expected useful life (nameplate age / fleet-average life for the asset class per EURELECTRIC or EurEau benchmarking data)
Maintenance history compliance (overdue PMs, skipped inspections, incomplete work orders per EN 13306 maintenance classification)
Sensor readings and trend analysis (DGA for transformers per IEC 60599, vibration for rotating equipment per ISO 10816, wall thickness for pipelines per EN 13509)
Environmental exposure conditions (coastal salt spray, flood zone location, chemical atmosphere, UV degradation , mapped against ECMWF climate data)
Loading relative to rated capacity (peak loading vs. nameplate, cumulative thermal stress per IEC 60076 loading guide, emergency overload events)
Historical failure rates for this specific asset class, manufacturer, and vintage across your fleet and CEER/EURELECTRIC industry benchmarking data
See Failures Before They Happen.
Reactive maintenance , running assets until they fail , costs 3-10x more than preventive or predictive maintenance (JRC European Commission research data). An unplanned transformer failure during a winter peak load event cascades into a multi-hour interruption affecting thousands of customers, an emergency replacement at 2x normal cost, and CI/CML or SAIDI minutes that accumulate against your regulatory performance targets. Argus analyses patterns across sensor data (dissolved gas analysis per IEC 60599, vibration signatures per ISO 10816, partial discharge per IEC 60270, oil quality per IEC 60422), maintenance history, ECMWF weather forecasts, and loading trends to forecast which assets are most likely to fail within 30, 90, and 365 days , so you replace them during a planned outage window, not at 2 AM during a winter storm.
30-Day Failure Forecast
Transformer TX-1482
Dissolved gas analysis per IEC 60599 shows accelerating hydrogen and acetylene generation , key combustible gas ratio indicates thermal fault exceeding 700 degrees C. 32 years in service, loaded at 94% of nameplate during winter peaks.
Pump PM-0923
Vibration amplitude exceeding baseline by 340% at bearing frequency per ISO 10816 , consistent with bearing inner race defect. Pump efficiency has dropped 12% over 6 months, indicating progressive mechanical degradation.
Valve VL-3341
Age at 92% of expected useful life for this valve type (cast iron butterfly). Last exercised 14 months ago , exceeding the 12-month exercise cycle per EN 13306 predetermined maintenance interval. Similar valves in this vintage have shown stem corrosion leading to inoperability.
Greater than 70% probability of failure within 30 days. These assets should be scheduled for immediate intervention , replacement, refurbishment, or load transfer to reduce stress.
40-70% probability of failure within 30 days. Schedule inspection and prepare replacement materials. Reduce loading if operationally feasible. Monitor daily for deterioration acceleration.
15-40% probability of failure within 30 days. Include in next maintenance cycle. Ensure replacement materials are in warehouse inventory. Monitor weekly for trend changes.
Less than 15% probability of failure within 30 days. Normal operations. Routine inspection schedule adequate. These assets are not consuming your attention or your budget.
Contributing Factors
- Accelerating degradation trend in sensor data (DGA gases doubling rate per IEC 60599, vibration amplitude exceeding 3x baseline per ISO 10816, increasing partial discharge activity per IEC 60270)
- Approaching or exceeding expected useful life with deteriorating condition indicators (not age alone , a well-maintained 50-year transformer can outperform a neglected 20-year unit, per EURELECTRIC fleet analysis)
- Loading above rated capacity during peak periods , cumulative thermal stress accelerates insulation ageing per IEC 60076 loading guide
- Severe weather forecast for asset location , ECMWF data for ice loading, Atlantic windstorm stress, flood risk, and lightning exposure increasing short-term failure probability
- Similar asset class failures in your fleet or in industry data , when one unit from a specific manufacturer/vintage fails, its siblings are statistically more likely to follow (CEER fleet correlation analysis)
- Overdue maintenance or inspection , a missed DGA test means you are flying blind on a transformer that may be producing combustible gases
Maintenance That Meets Every Standard.
Preventive maintenance is not just good engineering practice , it is a regulatory mandate with real consequences for non-compliance. The NIS2 Directive requires documented maintenance of critical infrastructure cyber systems. National safety authorities mandate integrity assessments on gas transmission pipelines within specific reassessment intervals per Seveso III. EU Drinking Water Directive (EU 2020/2184) mandates calibration and maintenance of water quality monitoring equipment. Missing a single compliance-mandated maintenance task creates audit findings that can escalate into enforcement actions from national regulatory authorities. Argus tags every maintenance task with the compliance framework that mandates it , classified per EN 13306:2017 maintenance taxonomy , so your maintenance planner knows exactly which tasks are compliance-critical and which tasks are discretionary.

Your Assets Tell a Story. Argus Reads It.
European utility infrastructure requires an estimated EUR 1.5 trillion in investment over the next 20 years (EURELECTRIC/EurEau/Marcogaz data). No DSO or water utility can replace everything , regulated tariff structures, TOTEX allowances, and construction capacity limit capital programmes to 2-3% of asset base per regulatory period. The utilities that manage this challenge successfully share one capability: they know which assets need attention now, which can safely defer, and which should run to failure because the consequence of failure is low. That knowledge , transparent, defensible, and data-driven , is what separates a network operator that earns its allowed return from one that faces regulatory performance penalties.
Data-driven asset decisions reduce unplanned interruptions by 25-45%, extend infrastructure useful life by 15-25%, and provide the ISO 55001-aligned evidence that national regulatory authorities demand when approving TOTEX allowances and performance incentive assessments. Every health score. Every failure forecast. Every maintenance recommendation. Transparent. Explainable. Defensible.
Stop guessing which assets need attention. Start knowing , with the confidence to defend every investment decision in front of your board, your national regulatory authority, and your customers.
