Quality-assured backup power

Our backup power systems are manufactured according to ISO 9001 and ISO 14001 standards. ISO 9001 is a quality management standard for businesses and organizations, ensuring continuous improvement and customer satisfaction. On the other hand, ISO 14001 focuses on environmental management, helping companies become more environmentally friendly and efficient. By adhering to these standards, we are able to produce reliable and eco-friendly backup power solutions. Additionally, we are proud members of Sinfra, an economic association that enables us to select the right technology, products, and services for our customers quickly and securely.

We generate security

Safer than any other insurance

Sweden has become the fourth largest per capita electricity consumer in the world over time. This fact makes us vulnerable to power outages and increases the need for action. Despite the significant investments made by electricity companies to improve the safety of our aging and overloaded power grid, the number of power outages continues to rise year after year. The consequences are costly, with society and businesses losing significant amounts of money annually. To address this challenge, the Swedish Energy Agency has proposed the installation of more backup power plants in critical infrastructure. Discover how backup power plants can provide protection and ensure a reliable power supply for your business.


We believe it is equally important for companies and organizations to ask themselves the same question:


How would your business be affected by a power outage?

Every day, we work tirelessly to protect you from both minor and major disasters by offering reliable and environmentally-approved power plants. With our power plants, you gain invaluable peace of mind that no insurance can provide. We conduct thorough needs analysis for each project to ensure that you always have access to electricity after our delivery. Our custom-made backup power plants provide you with security and assurance that you will never be without power, even during power outages.
