Electrical power
The Nordic countries are facing a gigantic engineering change. Solar and wind power are rapidly increasing, which places new demands on the power grid. Electric vehicles are coming on a broad front and with them an extensive charging infrastructure. As a leading partner in service and expertise, Prevas is at the center of the new electrical power revolution.
We must increase the pace towards our fossil-free, climate-smart future. The restructuring of the energy sector is an important step towards achieving the goal. And that's making the electrical power industry one of tomorrow's biggest growth industries.
The electrical power revolution has already started and is coming up to speed. The expansion of renewable electricity – mainly solar and wind power – is underway. To handle the often-varying power flows, a transition to smart grids is a must.
When the roll-out of electric cars and other electric vehicles takes off in earnest, the charging infrastructure must be rapidly expanded. This in turn places higher demands on the electrical grids, which must be expanded and modernized.
We'll see the expansion of new micro grids that supply communities or neighborhoods, as well as smart houses, that reduce electricity consumption and enable households to sell and buy electricity in a developed market. Much of this is happening now and it is happening fast. Major changes that require major engineering initiatives.
We operate in all areas of the electrical power industry:
- Transmission/Distribution/Substations
- Station automation
- SCADA/EMS/DMS
- FACTS/HVDC
- Battery banks
- Power plant projects (all types of generating stations)
- Wind power, solar power
With our expertise and experience of advanced engineering in Sweden's energy and electrical power centers, we are attractive employers for the most qualified engineers – from all corners of the world.
Project management
Our project managers lead and coordinate electrical power projects with responsibility for quality, budgets, time frames and follow-up. We have considerable variety in our assignments, both when it comes to focus and level. Our largest assignments are large complex international turn-key (EPC) projects.
Examples of assignment areas:
- Full responsibility both commercially and technically for projects.
- Leading project teams.
- Claim & change management.
- Risk management.
- Site inspections.
- FAT and SAT.
- Procurement of suppliers.
- Contractor calculations.
- Forecasting and investment assessments.

Primary construction (electrical and mechanical design)
Our consultants in primary construction are experts in complying with legal requirements and standards to ensure that projects are implemented within budget and on time. We often have a leading role in electromechanical construction in large and complex high-voltage, air- and gas-insulated projects in various power supply systems at all voltage levels (HV, MV, LV). We develop technical concepts, work with specifications and selection of components, as well as connection materials, preparation of station layouts, associated detailed drawings and documentation according to applicable standards, processes and customer specifications.
Examples of assignment areas:
- Technical calculations, purchasing specifications.
- Preparation of station layouts and detailed diagrams for primary devices (safety distances, grounding issues, etc.).
- Coordination of interfaces between design planning, steel construction (snow, wind and earthquake requirements) and component suppliers.
- Preparation of information for civil engineering and coordination of interfaces between all technology disciplines.
- BOM and cost calculations, variances and clarifications.
- Review of supplier designs, FAT plans, participation in FAT and SAT.
- Technical support in tenders and related documents.
- Site matters and final documentation.

Secondary construction (design of control systems)
Our consultants in secondary construction ensure that your projects are carried out within budget and on time, and that they meet the legal requirements and standards. We often have a leading role in electromechanical constructions in large and complex high-voltage, air- and gas-insulated projects in various power supply systems at all voltage levels (HV, MV, LV).
Examples of assignment areas:
- Responsible for the design of protection and control systems for HV and MV stations.
- Preparation of single-line diagrams, control diagrams, assembly and wiring diagrams, relay layouts and cable tables.
- Technical calculations and technical purchasing specifications for components in auxiliary power systems.
- BOM and cost calculations, variances and clarifications.
- Review of supplier designs, FAT plans, participation in FAT and SAT.
- Responsible for testing of control equipment both in the factory (FAT) and at the construction site (SAT and final inspection).
- Technical support in tenders and related documents.
- Site matters and final documentation.

Relay protection technology
Our consultants in relay protection ensure that your projects are carried out within budget and on time, and that they meet the legal requirements and standards. We often have a leading role in the electromechanical design of relays and control systems in large and complex high-voltage, air- and gas-insulated projects in various power supply systems at all voltage levels (HV, MV, LV).
Examples of assignment areas:
- Responsible for the design of relay and control systems for HV and MV stations.
- Configuration and parameter setting of relay protection, control panels and MicroSCADA.
- Preparation of selective plans to coordinate relay protection settings.
- Responsible for ensuring that the hardware configuration meets the set requirements and standards.
- Responsible for testing of relay and control equipment both in the factory (FAT) and at the construction site (SAT and final inspection).
- Technical support in tenders and related documents.
- Site matters and final documentation.
