The challenge

The business had grown over many years both organically and by acquisition. Partly as a result of this rapid growth, the operational processes relating to the sale and purchase of energy across the Group’s different trading entities were inefficient and unreliable. There was a significant risk of failure around these trading activities, due mainly to poor data quality and integrity. There were also many different data optimisation models in use for the calculation of the energy value and output, by the individual generating assets. Functional gaps in many of the models. Most were based on highly manual, excel interfaces which further added to the operational risk around the transfer pricing business processes.

The solution

Transfer Pricing (TP) solution for Uniper

Established robust and harmonised processes for transfer pricing management covering all energy asset classes, including coal and nuclear in all markets. Enhanced the functional scope of the optimisation models and tested them using scenario modelling across a range of scenarios to give various business stakeholders the confidence to rely upon them going forward. Installed a fully-auditable, “tamper-proof” transaction system for managing the invoicing of the entire power station production capacity, including cross-border transactions between different national tax systems. Embedded automated testing into the software development lifecycle to ensure quality throughout the product lifecycle and to support rapid, agile software delivery to address the evolving stakeholder needs.
