Uniper Wärme GmbH modernises SAP IS-U System

This modernisation marks a significant step in future-proofing the company’s application landscape, enabling enhanced cloud capabilities and cost efficiencies, while positioning Uniper Wärme to meet the dynamic demands of the energy sector.

The primary goal of this initiative was to modernise Uniper Wärme’s SAP landscape, moving from the outdated ORACLE database to the more advanced and powerful SAP HANA database. The upgrade to SAP S/4HANA Utilities has provided the company with an efficient, flexible, and scalable IT infrastructure, designed to support the business well into the future.

Uniper Wärme embarked on the modernisation project to overhaul an ageing ERP system that had evolved over the years to include a multitude of SAP and non-SAP modules and interfaces. With growing demands in the energy sector, this system no longer met the company’s needs, and a seamless transition was critical for the approximately 30 users.

A number of challenges were successfully navigated, including integrating existing system functions and ensuring the smooth migration from the ORACLE database. Professional support and comprehensive testing were vital in achieving a smooth transition, ensuring uninterrupted service to ERP customers during the process.

The modernisation project has been a resounding success, with Uniper Wärme now benefitting from enhanced cloud maturity, improved infrastructure efficiency, and the adoption of modern database technologies. The transition has enabled the company to adapt swiftly to evolving market conditions, while continuing to provide a reliable and sustainable energy supply.

Principal advantages of the SAP S/4HANA upgrade were: increased cloud maturity; cost-effective infrastructure; and more flexible, future-proof solutions.

Tobias Beck, Account Director at adesso commented: "We are delighted to have supported Uniper in its transition to SAP S/4HANA and to have been able to implement a more cost-efficient infrastructure and modern database technologies in the Heat division. This will improve Uniper Wärme's cloud maturity and enable the company to meet future challenges with agility. We are proud to be part of Uniper's journey and look forward to our continued collaboration."

Libero Raspa, Managing Director of adesso UK, commented: "With adesso's proven track record on major projects such as Uniper's, we are well positioned to support UK organisations in their own SAP transformation and ensure they are prepared for future challenges with agility and efficiency. We look forward to bringing this expertise to the UK market and supporting our clients' growth and innovation."

With its modernised infrastructure, Uniper Wärme GmbH is well-positioned for continued success in a rapidly evolving energy sector, ensuring that it can meet future challenges with confidence and agility.
