invokers developed the E.ON Business Portal, which is a portal for E.ON's key accounts. Customers are, for example, industrial companies, contractors, property managers and housing companies. They are now able to log in to their own pages and not only get an overview of their energy situation, but also get useful information to control their electricity, gas and district heating.

Analyzing and comparing energy consumption across customer facilities, all the way to timetable-level, allows customers to monitor their energy consumption and identify irregular usage patterns.

These follow-ups across facilities mean that they have the opportunity to capture errors and optimize processes, which is something that can be seen on the bottom line when it comes to energy consumption for several millions of SEK.

In addition, the portal improves administrative services for customers. This allows for example housing associations with numerous of properties, to easily manage invoices and costs.  


EPiServer on Microsoft  Azure, SAP NetWeaver, HTML5.

The portal runs on an EPiServer, with the user interface and design implemented in HTML5/CSS3. After we redesigned the platform, it now runs with a flexible and efficient integration layer against SAP as well as a robust, responsive and solid front-end architecture.

The solution is hosted on Microsoft Windows Azure and E.ON benefits massively from the incredible flexibility of this great cloud platform.


Business are facing only greater demands on web solutions, and E.ON's business capacity had to be developed to accommodate the changing conditions in the consumer market. In close collaboration, we improved architecture, development processes and technology utilization.

The portal is now a significant advantage when E.ON starts dialogue with new customers, and customer satisfaction is significantly improved. invokers has created a large customer portal that is agile, flexible and modern and E.ON now has a greater ability to attract and maintain large energy customers.


E.ON struggled with an expensive and complex system that complicated processes for both E.ON and their customers. E.ON, like most other companies, is in a world filled with rapid changes, where customers expect and require smart digital services. E.ON wanted an efficient platform that could be expanded quickly and in a stable manner, to give them the opportunity to offer new, elegant features and digital services to their customers.
