E.ON Next


Callisto successfully migrated 1.7m customers of npower's domestic portfolio to E.ON Next and their newly acquired Kraken Platform including DC, DA, gas portfolio (MRA) and dynamic Meter Reading Mechanism. Kraken did not have the capability to utilise industry processes to communicate the MRA updates as E.ON Next required. 

What we did and how we did it

Callisto confirmed that E.ON Next required industry mechanism (Proteus) and worked with E.ON Next and Octopus developers by:

Closely monitoring extreme backlog volumes (800k) of appointment migration flows over a period of days and flagging issues, impact and resolution as a priority

Benefits to E.ON

E.ON Next were able to complete the agent appointments in their system set up, and more importantly, efficiently automate dual fuel cyclic read requests on a portfolio of 1.7m customers with minimal manual intervention or further development.
