Our most important customer group

Our portfolio customers are made up of our 11 shareholder customers and other energy supply companies, which pass on their portfolio to OpenEP to manage.

  • The basic package covers all the services that have to be fulfilled to manage a portfolio effectively. Besides portfolio management and optimisation, these also include the services of market access and balance group management.
    All portfolio customers sign up to the basic package, even those with flexible long-term contracts.
  • The add-on services complement the basic package for customers who want full coverage.
    The add-on services are available individually to take the situation of the full coverage customer into account. The add-on services include portfolio analyses, sales forecasts, storage management etc.
  • Individual services cover all other needs such as consultancy, concept design, planning etc., but also balance group management outside its own balance Zone.

In terms of further development, we periodically check the composition and arrangement of the range of services for our portfolio customers.


New, additional gas supply companies are welcome.
