HVDC & POWER INFRASTRUCTURE
SOLUTIONS FOR ENERGY PROJECTS
Critical infrastructure projects require technical understanding, practical execution and strong coordination across complex systems and installations.
This is why we founded Sirius Energy Infrastructure — a dedicated department focused on technical project management, site management and electrical infrastructure solutions for complex systems and facilities.
Since 2010, we have delivered specialized expertise across energy and industrial sectors, with particular focus on HVDC systems, high-voltage distribution and critical infrastructure projects.
Our MASKINMESTRE combine technical understanding with practical on-site experience, where safety, quality, reliability and performance remain central to every project.
We specialize in electrical infrastructure, from high-voltage distribution systems and HVDC links to critical process systems within pharmaceutical and data centre environments.
Our expertise includes technical project management, site management, substation commissioning and SCADA commissioning for complex infrastructure projects involving high-voltage substations, transmission systems and critical installations.
We work with technical systems and subsystems including HVAC, generators, LV systems, cooling, fire protection and auxiliary systems for critical infrastructure and data centre projects.
Through projects such as Viking Link, Sirius Energy has contributed technical support and site management on one of Europe’s largest HVDC interconnector projects.
Our Infrastructure department provides experienced technical personnel for project management, commissioning, QA/QC and HSE management on large and complex construction sites.

FAQ - HVDC Infrastructure Solutions
What is an HVDC system?
An HVDC system (High Voltage Direct Current) is used to transmit large amounts of electricity over long distances with minimal energy loss. The technology is widely used in offshore wind, HVDC interconnectors, high voltage substations and critical energy infrastructure, where stable and efficient power transmission is essential.
How does Sirius Energy handle HV substation projects?
Sirius Energy supports HV substation projects through technical project management, site management, commissioning, QA/QC and coordination of complex electrical installations. We stay involved throughout installation, testing and commissioning with focus on safety, quality and reliable operation of critical infrastructure systems.
What does a high voltage distribution system include?
A high voltage distribution system includes technical components such as transformers, GIS systems, busbars, SCADA systems, relay protection and auxiliary systems used for safe transmission and distribution of electricity within critical energy infrastructure.
Does Sirius Energy offer substation commissioning?
Yes. Sirius Energy has extensive experience with substation commissioning on complex energy and infrastructure projects, including FAT/SAT coordination, functional testing, QA/QC, technical documentation and commissioning coordination for high voltage substations and critical data centre infrastructure.
What types of projects does Sirius Energy work on within high voltage power distribution?
We support high voltage power distribution projects within transmission networks, substations, data centres, offshore wind and critical energy infrastructure. This includes HVDC interconnectors and complex transmission and infrastructure projects such as Viking Link.
What systems does Sirius Energy work with?
We work with technical systems such as HVAC, generators, SCADA, PMS, low voltage systems, cooling, fire protection and high voltage infrastructure for critical facilities, substations and data centre infrastructure.
Why is commissioning important in critical infrastructure?
Commissioning ensures that technical installations and critical systems operate correctly, safely and in accordance with project specifications before becoming operational. This is especially important in HVDC systems, high voltage substations and data centre infrastructure, where reliable operation and high uptime are essential.
What experience does Sirius Energy have with energy infrastructure?
Sirius Energy has experience from complex energy and infrastructure projects across Europe, including HVDC links, high voltage substations, transmission networks, offshore wind and critical data centre infrastructure. Our consultants support projects through technical project management, site management, commissioning and coordination of critical technical systems.
What does site management involve in complex energy projects?
Site management involves technical coordination and management of construction site activities with focus on safety, quality, progress and collaboration across disciplines. Sirius Energy supports site management on complex energy and infrastructure projects, ensuring safe and efficient coordination of installations, commissioning and critical technical systems.
How does Sirius Energy manage QA/QC on critical infrastructure projects?
Sirius Energy manages QA/QC through technical documentation, inspections, FAT/SAT coordination, testing procedures and quality assurance of installations and critical systems.
