Acea Energia accelerates meter-to-cash processes with an upgrade to SAP S/4HANA

Italian multi-utility Acea SpA is the top national operator in the water sector, serving 9 million customers. To more effectively serve its customers, Acea SpA planned to digitally transform its entire business and subsidiaries within three years. In light of the ambitious timeline, the company engaged Atos to help transition to SAP S/4HANA as its digital core.

The challenge


In an organization that has existed over 100 years, change can be difficult. The organization required a complete overhaul of its digital infrastructure using a measured approach. The energy company’s monthly billing invoicing-printing (UBIP) process was taking five days total which was becoming unmanageable. It was choking billing capacity, delaying cashflow and stunting growth. Acea Group needed to upgrade the billing and credit management system of its highly visible energy subsidiary, Acea Energia.

The solution


Atos managed the upgrade of Acea Energia’s SAP Utilities (IS-U) from ECC (ERP Central Component) to S/4HANA. The new system integrates a range of business processes such as ERP, CRM, human capital management, mobile workforce management, as well as billing and credit management. The data migration executed for this upgrade was completed over one weekend (the minimum go-live window) with no changes to data structure, no discards on data transformation and no interruptions to system availability.

Business benefit


With a reliable digital platform to manage its billing and credit processes, Acea Energia is delivering usage data to its customers much faster. In addition:
• The monthly billing and invoicing process now takes 40% less time, which has expedited cashflow.
• The shift to a manageable digitized billing system saved time and money.
• The project was completed in 8 months allowing Acea Energia to enjoy the benefits more quickly.
