Solutions for the energy industry

Engineering for critical energy operations

Modernise without downtime
Integrate legacy and new systems
Secure OT and grid communication

How we can help you

We modernise the backbone of the energy chain, helping teams keep assets performing, secure, and compliant without disruption.

  • Legacy SCADA and RTU systems

  • Fragmented industrial protocols (IEC, Modbus, DNP, OPC UA, MQTT)

  • Strict uptime requirements and limited maintenance windows

  • Increasing OT cyber security pressure

  • Telemetry complexity affecting reporting

What we do

Expertise at every step of the energy path

1 / Production

We support mission-critical production environments where safety, uptime and compliance are central. With deep SCADA, automation and embedded engineering expertise, we stabilise operations and keep systems aligned with IEC and industrial standards.

  • SCADA dashboards and RTU automation logic
  • Substation automation: telecontrol, transformer tap control, auxiliary supply, circuit-breaker automation
  • Embedded systems and RTUs: development and international certification
  • OT cybersecurity: network and equipment detection, secure protocols
  • Communication protocols: IEC (101, 104, 103, 61850), DNP, Modbus, OPC UA, Profibus, SNMP and legacy

2 / Transmission

We help operators run a stable, responsive and compliant grid. We modernise telecontrol safely, strengthen alarm and event handling and ensure secure, high-integrity data flows across IEC-backed utility protocols.

  • SCADA telecontrol and operations management: data acquisition, alarms, events, configuration and deployment
  • Trading applications: consultancy and development
  • Reporting and management: web services, big data dashboards and management tools
  • Communication protocols: IEC (101, 104), DNP, ICPP, Modbus, Kafka, MQTT and legacy

3 / Distribution

We enable reliable metering, EV infrastructure and field device communication. Our expertise in OCPP, DLMS and device connectivity, combined with OT-grade edge security, keeps distribution systems secure and responsive.

  • End-user applications for Android, iOS and the web
  • Dashboards, alarms, maintenance and operational management
  • Cybersecurity for infrastructure and protocol communication
  • EV and metering protocols: OCPP 1.6, DLMS
  • Battery testing: lab testing and software for test environments

Success story

Monitoring solution for electrical substations

The primary objective of this comprehensive application is to provide analysts with the capability to monitor all activities within an electrical substation.

  • Manage devices across different zones and geographical locations in the substation

  • Track events like security alerts and device communications.

  • Monitor real-time alerts, and analyze past alerts to determine issue causes.

Protocol testing and certification support

For VIVAVIS, we handled the end-to-end testing of their IEC 61850 implementation for the ACOS 750 platform, ensuring real-time substation communication met strict international standards. Our work de-risked their certification process, eliminating costly delays and enabling VIVAVIS to compete confidently in public tenders.
