The Challenges

Platform and business unit overarching scope

Provide a consistent customer experience on both digital channels – mobile and web 

One platform to serve both residential (B2C) and business customers (B2B)

Providing information and initiating transactions such as payments or payment history for both, electricity and gas contracts

Integrated Loyalty program

The channel should be managed through an administration console for the channel admins 

Demanding integration requirements

Integration of the digital channels with various core systems across different business divisions (electricity and gas)

Integration of 3rd party services to provide real-time market information to support buying decisions

Integration of marketing and shop functionalities within the channel

Complex project environment

The project had to integrate and span over multiple business divisions historically using different project and delivery methodologies from traditional models to agile development.   


Together with the teams of Stredoslovenská Energetika the digital channels were successfully delivered on time and scope.

The new digital channel provides among other features

  • Native front-ends for Android, iOS and web
  • Ultra-secure authentication and log-in (cross channel)
  • Integrated Loyalty system
  • Overview of contract and payment information
  • Payment functionalities
  • Real-time electricity market pricing
  • Secure direct messaging to customer
  • Marketing & Sales functionalities such as banners and eShop
  • Administration console as a central function to manage the channel


The launch of the customer platform opened completely new possibilities and convenience for Stredoslovenská Energetika’s customers, allowing Stredoslovenská Energetika to provide a fully digital experience to their customers.

For the complex technical realisation various Zentity products have been combined into an open and flexible digital architecture

  • Zentity Digital Server as the heart of the solution was used for integration into SSE’s core systems as well as 3rd party integration
  • Push Server enables SSE to securely communicate to their customers directly
  • Integrated Loyalty gives the freedom to actively and flexibly manage the loyalty program
  • Auth Server was used to provide an easy yet secure identity management
  • Zentity Admin Console was implemented to provide intuitive and detailed channel management functionalities
  • Translation Hub ensures that alls languages versions of the channel are being managed in a coordinated and easy way, allowing any translation changes to be rolled out into the apps without creating a new version of the app.
  • All front-ends are native developments

The architecture and it’s components have been designed and put together so that all digital channels can now be centrally maintained. It allows Stredoslovenská Energetika to flexibly and quickly integrate new services for its customers in the future.
