How Sweco transformed its substation design

Learn more about Sweco

Sweco Norge, one of Norway’s leading engineering companies, like many others, faced major challenges in the planning and design of substations before the introduction of primtech.

The challenge

The previous use of simple 2D and 3D programs, without an intelligent library or predefined templates, slowed down the planning process considerably. The lack of reusable components led to repetitive manual work, making it difficult for engineers to focus on more important tasks. Without a specialized software solution for high-voltage substation design and engineering, engineers struggled to meet stringent specifications. This was equally true for brownfield and greenfield projects. Customers in the industry, such as the Norwegian transmission system operator Statnett, have very strict design and engineering guidelines.

The Solution

After evaluating several options, Sweco chose primtech for its intelligent library, ease of use and compatibility with AutoCAD. Sweco has now been using primtech for five years, with around 20 users actively working with the software on projects every day. Both electrical and power engineers benefit from primtech’s powerful features. The ability to reuse components through the component library and the self-created template library, which grows with each project, has revolutionized the design process.

The Results

The implementation of primtech has brought significant improvements for Sweco:

  • Increased efficiency and speed:
    Sweco engineers are now much more efficient and can complete designs in a third of the time previously required.
  • Accurate and valid results right from the start:
    The introduction of primtech 3d has led to a significant improvement in design accuracy, which is particularly important when adhering to strict customer specifications. Engineers can now quickly design and present detailed models of substations to clients, which has improved communication and significantly reduced rework.
  • Library integration for efficiency and consistancy:
    The primtech library, combined with Sweco’s own template and component libraries, has streamlined the design process. This has avoided starting from scratch on every project, speeding up workflows and ensuring consistency across all projects.
  • Flexibility and freedom:
    The primtech library, combined with Sweco’s own template and component libraries, has streamlined the design process. This has avoided starting from scratch on every project, speeding up workflows and ensuring consistency across all projects.
  • Improved training and access to new workers:
    Sweco’s internal training system, built on the primtech INSIDE platform, has helped new employees quickly acquire the required skills. By incorporating training videos, guides and checklists into Sharepoint, Sweco ensures that also less experienced engineers are well prepared to start working on real projects shortly after induction.

Customer Reviews

The library in primtech is one of the most usable things for us. The possibility of quickly designing with intelligent components, and the fact that we already used AutoCAD, made primtech the obvious choice.


We are significantly more efficient with primtech. Our design time has been cut to one-third, and we are now able to deliver better results faster. It’s much easier to show these designs to our clients, which has improved our project workflows.


primtech is one of our most important programs, and it’s used daily. Our training program, based on primtech INSIDE and our own Sharepoint site, gets new and yet less experienced employees to a usable level fast. This has been key in ensuring that our team can focus on what matters – designing substations, not modeling objects from scratch
