Keep every worker safe across a live network.
For TSOs, DSOs, generation and utilities. We design contractor and lone-worker safety, geofenced high-voltage exclusion, and asset- and tool-tracking programmes for substations,
plants and field sites — engineered for harsh, regulated environments. Hardware-agnostic across UWB, BLE, active RFID and GPS.
Energy & utilities: the use case, and the numbers it moves.
The right radio for each job — chosen, never sold — mapped to your use case. That is what makes the ROI fast.
1 · Permit
Permit-to-work is tied to live presence in the zone.
2 · Locate
Lone workers are located across substations and plants.
3 · Protect
Duress and zone-breach alerts fire in real time.
UWB → zones · BLE → workers · LoRa → wide-area
What we keep seeing.
Lone workers are invisible
A technician working alone at a remote substation has no reliable way to raise an alarm — and no one knows their exact location if something goes wrong.
Live zones rely on procedure
Keeping people clear of energised equipment during an outage depends on a permit-to-work paper trail and trust, not a hard interlock.
Contractors come and go
During major outages hundreds of contractors flood a site. Knowing who is where, and who has left, is a clipboard exercise.
The use cases that consistently pay back.
Lone-worker safety & SOS
Man-down detection, duress alarms and precise location for workers across remote and field sites.
Geofenced HV exclusion
Alerts and interlocks that keep personnel clear of energised equipment during switching and outages.
Contractor & visitor control
Live on-site register, induction status and automatic exit reconciliation during outage peaks.
Asset & tool tracking
Locate test equipment, switching gear and high-value tools across substations and depots.
Mustering & evacuation
Verified headcount at the muster point in seconds for emergency response.
Outage workforce analytics
Where the crews are and how work is progressing across a distributed outage.
Hardware & software ecosystem

Where we plug in

What good looks like.
What we design and document to
IEC 62443 (OT security) · ISO 45001 (occupational health & safety) · ATEX 2014/34/EU and IECEx where applicable · lone-worker standards (e.g. BS 8484) · permit-to-work alignment.
Where the payback shows up.
Substation outage safety
Contractor and lone-worker tracking with geofenced safety zones across a multi-substation outage programme.
Lone-worker SOS
Man-down and duress alerting with precise location for field technicians at remote sites.
Tool & equipment control
Test gear and switching equipment tracked across depots and substations, cutting loss and search time.
During outages we put hundreds of contractors onto live substations. Geofenced HV exclusion and lone-worker SOS gave us 100% muster accountability and a verifiable record of who was where. It worked because TRACIO built it around our permit-to-work process and ISO 45001 safety case, not as a bolt-on.Safety & Outage Manager · European TSO · EMEAAnonymised at the client’s request.

Solutions for this industry
Relevant case studies
Common use cases — what we keep seeing.
Substation worker safety and arc-flash protection
Problem: Substations contain arc-flash hazards; workers entering live zones require permits, PPE verification and standoff distance enforcement.
Tech mix: BLE-AoA on worker badges, zone-access readers, integration with permit-to-work and CMMS.
Outcome: Arc-flash incidents prevented, standoff compliance evidence, audit-ready PPE-and-permit verification.
Wind turbine field-service technician dispatch
Problem: Wind farms span 100+ km with hundreds of turbines; dispatching technicians efficiently requires real-time turbine status and tech location.
Tech mix: GNSS on field vehicles, BLE-AoA on technicians at turbine sites, integration with SCADA and CMMS.
Outcome: Truck-rolls per turbine-fault reduced 25-40%, technician utilisation improved, MTTR reduced.
Power-line right-of-way (RoW) inspection
Problem: Transmission and distribution RoW inspection is slow and inconsistent — drones, ground crews and helicopters all generate data that must be integrated.
Tech mix: GNSS + LiDAR on inspection drones, Passive RFID on pole and equipment, integration with asset-management.
Outcome: Inspection cycle time reduced 50%+, fault-detection earlier, regulator-required inspection compliance.
Battery storage (BESS) asset management
Problem: Grid-scale battery storage installations contain thousands of modules; module health monitoring and warranty tracking are critical.
Tech mix: Cell-level temperature and SoC sensors, gateway coverage in BESS containers, integration with EMS/BMS.
Outcome: Cell-level fault detection in <1 hour, warranty claims documented per module, BESS availability improved.
Hydroelectric / hydrogen-production worker tracking
Problem: Dam and hydrogen-production sites have confined spaces, hazardous areas and remote locations requiring lone-worker safety and mustering.
Tech mix: UWB or BLE on workers, hazardous-zone access control, integration with safety-management.
Outcome: Worker safety compliance, mustering verified, audit-ready records for OSHA/regulators.
Smart-meter network rollout management
Problem: Utility AMI rollouts deploy millions of meters; installation, activation and field-service tracking are critical.
Tech mix: GNSS on installer trucks, mobile app with location-aware install workflow, integration with MDM and CIS.
Outcome: Install productivity up 20-30%, first-time-right rate improved, customer activation faster.
Critical-infrastructure security and intrusion detection
Problem: Energy infrastructure (transmission stations, generation plants, pipelines) is critical national infrastructure with security requirements.
Tech mix: Perimeter sensors, BLE-AoA on authorised personnel, integration with security-management and SCADA.
Outcome: Intrusion events detected in real time, false-alarm rate reduced, NERC-CIP / NIS2 compliance evidence.
Solar farm panel-cleaning workflow
Problem: Utility-scale solar requires regular panel cleaning; cleaning fleet (manual or AMR) requires routing and verification.
Tech mix: AMR or GNSS on cleaning rigs, integration with O&M software, production-data correlation.
Outcome: Soiling-loss reduced 5-10%, cleaning frequency optimised per panel, O&M cost per MWh reduced.
EV charging-station fleet management
Problem: Charging-station networks need real-time status, queue management, and field-service dispatch.
Tech mix: Connected charging-stations, GNSS on field vehicles, integration with charging-network OS and CRM.
Outcome: Charger uptime improved, field-service efficiency up, customer satisfaction improved.
Predictive maintenance on generation assets
Problem: Turbines, generators and transformers are capital-critical; unplanned outages affect grid reliability and revenue.
Tech mix: Vibration, temperature, acoustic and oil-analysis sensors via LoRaWAN, integration with CMMS and PdM platform.
Outcome: Unplanned outages reduced 30%+, mean-time-between-failures up, lifetime-cost-of-asset reduced.
Frequently asked questions
How does RTLS keep workers safe across an energy network?
Lone-worker and man-down protection, mustering, and zone awareness across substations, plants and remote sites mean a worker in trouble is located and reached quickly, even alone in the field.
Does it work across dispersed and remote assets?
Yes - GNSS and LPWAN cover wide, remote networks; RTLS covers plants and confined spaces; together they give one safety and asset picture.
Can it track high-value and critical assets?
Yes - tools, mobile plant and critical spares are tracked to cut loss and downtime, and condition sensors flag failing equipment before it trips the network.
Does it support compliance and permit-to-work?
It underpins lone-working duty-of-care and emergency-response obligations, with auditable records of presence, alerts and response.
How does it integrate with our systems?
Safety, location and condition data feed your control-room, EAM or CMMS and permit systems so the information reaches existing workflows.
