Meeting the energy demands of the future requires both smart solutions and reliable technology. When Kalmar Energi embarked on modernizing its power plant, its goal was clear: to establish a safe, reliable, and sustainable electricity supply capable of supporting the needs of today and for years to come.
The solution came in the form of ABB’s SMISSLINE TP – an innovative system that combines exceptional reliability with unmatched flexibility. Together, ABB and Kalmar Energi are laying the foundation for a future-ready energy system across the Kalmar region.
Ensuring reliability and continuous uptime
For power grid companies, operational reliability and uptime are paramount. Kalmar Energi, a leading energy company in the Kalmar region in Sweden, prioritized these by upgrading its switchgear and investing in new control cabinets. The company chose ABB’s SMISSLINE TP, the world’s first plug-in socket system, to enhance system resilience and flexibility.
This pioneering solution allows maintenance and expansions to be carried out without disrupting the power flow, ensuring an uninterrupted and reliable energy supply - both now and in the future.
Evert Karlsson, Automation Engineer at the automation consulting firm Pronecta, was involved in developing the electrical design for control cabinets and switchgear. He explained:
For Kalmar Energi, staff safety and uninterrupted operations were critical. We needed a solution that would allow us to perform maintenance, upgrades, and expansions without affecting ongoing operations. SMISSLINE TP was the obvious choice – its compact design, flexibility, and ability to meet the project’s high standards made it the perfect fit. It's a solution we will definitely rely on for future projects.

A flexible, future-proof energy solution
ABB’s SMISSLINE TP has become an essential component of Kalmar Energi’s modernization efforts. Thanks to its unique plug-in technology, components can be replaced in just seconds - quickly, seamlessly, and without downtime - revolutionizing how control cabinets are maintained and upgraded.
The system also integrates effortlessly with standard components such as residual current devices, surge protectors, and motor group starters. As a result, it offers a scalable, future-ready solution that meets today’s stringent requirements while preparing for tomorrow’s grid challenges.
“SMISSLINE TP enables us to make adjustments that save significant time and effort,” Torbjörn Cras, Maintenance Engineer at Kalmar Energi, emphasized. “Shutting down cabinets would have major consequences for the entire facility, so being able to perform upgrades without disrupting operations is a huge advantage.”
A long-term partnership for sustainable energy
Kalmar Energi has relied on ABB’s comprehensive portfolio of low and medium-voltage products to advance its power infrastructure for years. From standardized power distribution solutions to energy-efficient motors and advanced switchgear, ABB has played a key role in supporting Kalmar Energi’s growth and modernization.
Among ABB’s solutions, SMISSLINE TP stands out as one of the most proven technologies in the industry. With over 25 years of success in the energy sector, it has become a benchmark for flexibility and reliability.
“Modern facilities are increasingly complex, and any downtime can significantly impact productivity and efficiency. As energy companies navigate the energy transition, selecting solutions that offer both flexibility and reliability is essential,” highlighted Roger Wester, Sales Engineer at ABB. “SMISSLINE TP meets these needs, allowing maintenance and upgrades without disrupting operations. Its adaptable design ensures it can evolve with the changing demands of the energy sector, making it a crucial component for the future of energy distribution.”
