Biggest challenge
Condition signals and inspection results insufficiently converted into work priorities
Biggest opportunity
Risk-based maintenance and work chain
The greatest value is created not by more alerts, but by a clear and safe path from asset risk to completed work and measured results.
Energy infrastructure maintenance operating model
Activities include electrical, gas, heating and other energy infrastructure inspections, planned maintenance, fault resolution, emergency works, testing and reconstruction. Value is determined by the ability to allocate maintenance resources to the highest-risk assets, safely prepare works and return each repair outcome to asset history.
Work preparation is a critical part of maintenance
Disconnections, permits, diagrams, competencies, materials and equipment determine whether work will be safe and productive.
Asset condition must be continuously updated
Inspections and repairs must change the structured condition profile, rather than remain in attachments.
Emergency and planned work use the same data foundation
Asset diagram, customer impact, teams, parts and recovery actions must be accessible in one place.
Market and technology context
The value of energy infrastructure maintenance is driven by the need to better utilise existing networks, manage ageing asset risk and reduce disruption duration. Digital inspections and condition models must be implemented alongside rigorous OT, safety and qualification controls.
Ageing infrastructure and limited maintenance resourcesInspection and investment priorities must increasingly be based on actual asset risk.
Shortage of qualified workersMobile context, remote expert support and knowledge preservation become critical.
Cyber, physical and climate resilienceThe maintenance process must simultaneously manage OT security, employee risk and service continuity.
Typical operating process
01
Asset risk and inspection planning
Criticality, age, load, environmental conditions and failure history are converted into inspection priorities.
02
Inspection and defect assessment
The technician records measurements, photographs, condition, cause hypothesis and required action.
03
Work preparation
Schematics, isolations, permits, competencies, materials, specialist equipment and contractors are verified.
04
Repair or reconstruction
Work is performed, replaced parts are recorded, along with actual configuration and deviations.
05
Testing and return to operation
Measurements, protection, safety conditions and actual asset condition are confirmed.
06
Update of outcome and risk
Failure recurrence, maintenance effectiveness, investment needs and customer impact are analysed.
Digital maturity pathway
0
Calendar-based maintenance and paper evidence
Inspections are scheduled according to a timetable, whilst defects, permits, photographs and tests are stored in separate documents.
1
Digital tasks and separate asset systems
GIS, SCADA and EAM are used, but signals, asset criticality, work, parts and customer impact are not interconnected.
2
Mobile closed-loop work process
The technician receives object information, records actual work, materials and evidence, and the task is closed with mandatory checks.
3
Risk-based maintenance in selected asset area Typical current situation
In selected asset classes, criticality, condition signals, inspections, work preparation, mobile execution, tests and updated asset condition form a single cycle, but coverage is not yet uniform across the entire infrastructure portfolio.
4
Integrated work preparation and recovery Siektina
Disconnections, safety permits, crew competencies, materials, testing and customer communication are managed in a single chain.
5
Forecasted asset risk and investment
Condition models are used to support maintenance, replacement timing, spare parts requirements and capital planning.
Key finding
Digitalisation of energy infrastructure maintenance must create a closed loop from a condition signal or inspection through to a safely prepared work order, testing and updated asset condition.
The first version should cover one critical asset class and an actual crew workflow, rather than a catalogue of the entire infrastructure portfolio or an unvalidated predictive model.

Problemos
Most common digitalisation issues
Issues arise between asset risk, inspections, work preparation, safety permits, crew performance and updated asset condition.
Condition signals and inspection results insufficiently converted into work priorities
Critical
SCADA events, thermography, measurements, defects, failure history and asset criticality are presented in different systems.
Consequences
Maintenance planners assess risk manually, so highest-impact assets do not always receive priority in time.
Maintenance relies too much on calendar rather than actual asset risk
Critical
Age, load, environmental conditions, condition measurements, failure history and customer impact are not used in a single decision model.
Consequences
Unnecessary inspections are performed, whilst high-risk assets may remain inadequately maintained.
Work preparation does not cover all technical and safety dependencies
Critical
Disconnections, workplace preparation, permits, diagrams, protection settings, competences, specialised equipment, materials and contractors are checked separately.
Consequences
Work is delayed on site, downtime increases, as do unproductive call-outs and safety risk.
During emergency work there is no single view of the situation and restoration
Critical
SCADA events, network diagram, affected customers, crews, spare parts, contractors, communication and estimated restoration time are managed in different workplaces.
Consequences
Decision-making slows down, communication is duplicated and it is difficult to manage restoration priorities in real time.
Asset and technical data fragmented across systems
High
Lines, cables, substations, transformers, pipelines, heating networks, protection and automation assets are identified differently in GIS, SCADA, EAM, ERP and document systems.
Consequences
Difficult to link failure, work, costs, risk and investment need to a specific physical asset.
Work preparation, crews and materials coordinated separately
High
Isolations, schematics, permits, competencies, specialist equipment, materials, contractors and work window are verified in different workplaces.
Consequences
Work is postponed on site, resulting in increased unproductive call-outs, downtime and safety risks.
Inspection and maintenance priorities are insufficiently based on asset risk
High
Asset criticality, age, load, environmental conditions, condition measurements, failure history and customer impact are assessed in separate spreadsheets.
Consequences
Limited maintenance resources are allocated according to calendar or individual experience, and the highest-risk assets may remain insufficiently maintained.
Defect, repair and test results do not feed back into the asset condition model
High
Photographs, measurements, replaced parts, protection tests, actual diagrams and technician conclusions remain in reports or attachments.
Consequences
The next decision is based on outdated condition, diagnostic procedures are repeated and it is difficult to assess maintenance effectiveness.
Asset replacement and reconstruction plan relies on inconsistent history
Medium
Condition, failures, repair costs, criticality, customer impact and climate risk are analysed in different models.
Consequences
Difficult to compare continued maintenance, partial reconstruction and asset replacement based on whole life-cycle value.
Compliance, safety and environmental data are collected during reporting
Medium
Evidence of inspections, defects, protection tests, work permits, crew qualifications, contractors and incidents is gathered from different systems only before an audit or report.
Consequences
Report preparation is lengthy, data origin is difficult to trace, and non-compliance is noticed too late.

A task cannot proceed to execution until disconnections, permits, qualifications and required equipment are verified.
The mobile workplace must operate offline
Critical infrastructure is often in locations where connectivity is unreliable, so data must synchronise later.
The technician's conclusion must change the asset condition
A photo or report must not remain merely an attachment; key measurements and the conclusion must update the structured asset profile.
OT data must be accessible only on a need-to-know basis
Business and mobile systems must not receive excessive management rights or direct access to critical OT systems.
The maintenance priority must be explained
The asset risk score must show which signals, failures and impacts determined the decision.

Frequently asked questions
Which asset group is best to start with?
Choose a critical, sufficiently homogeneous asset class that undergoes many inspections, experiences recurring failures and for which downtime or call-out costs can be clearly measured. One coherent process will deliver more value than a general asset catalogue for the entire network.
Does an EAM or CMMS system not already solve the maintenance problem?
It can serve as a foundation, but value depends on data quality and integration with GIS, SCADA, mobile workplace, warehouse, qualifications and work permits. If the technician still searches for diagrams in files and completes the protocol after the work, the process is not closed.
When is it worth applying predictive maintenance?
When for the selected failure type there are sufficiently reliable condition signals, failure history and a clear action that can be taken upon receiving an alert. The model should not be the first step if asset objects, work codes and actual outcomes are not yet linked.
How to ensure that the mobile system does not hinder technicians?
It must work offline, automatically present object context, use short inspection scenarios and allow evidence to be collected during work. Forms need to be designed together with crews, not existing paper protocols transferred field by field.
How to securely connect OT and business systems?
Use segregated integration zones, read-only data flows, the principle of least privilege and a clear event audit trail. Mobile or analytics systems should not directly control critical equipment if there is no separate security architecture in place.
How to calculate payback?
Measure downtime avoided, shorter restoration time, fewer repeat call-outs, a higher proportion of work completed on first visit, lower number of emergency works and more accurate asset replacement timing.
