Exelon PHI Unlocks Resilience in the Cloud

To future-proof utilities migration

5-MINUTE READ

Call for change

New pressures on outdated systems

Exelon, a Fortune 100 energy company, recognized the need to modernize its infrastructure—particularly for Exelon PHI, a subsidiary that serves two million customers in the U.S. mid-Atlantic and Northeast.

PHI’s legacy SAP® and non-SAP applications portfolio, which handled key business functions including energy meter analysis and customer billing, was dated and quickly going out of support. This was creating pain points throughout the business—for employees and customers alike.

To help future-proof its systems, PHI reached out toArrk. Together, they partnered to upgrade its tech platform, decrease operations costs and provide greater reliability across all touchpoints.

Customer Services Representatives spent 80% of their time transferring customers account between locations.

When tech meets human ingenuity

Operational efficiency in the cloud

The joint team designed a smart brownfield migration and systems upgrade from on-premise servers and application software to the modern cloud.

The lift involved porting its legacy SAP platform to SAP S/4HANA®, an enterprise resource planning system that can execute transactions and analyze data with artificial intelligence (AI) in real time. Solving data replication issues also translated into improved customer service and billing operations.

The project and its direction were decided over the course of 18 months, but all of PHI’s highly customized systems and databases were migrated in full, with only 48 hours of service downtime.

A valuable difference

Powering a new era of resilience

Together, the team of 250-plus people across four countries executed nearly 1,000 specific tasks, including reducing PHI’s data footprint from 50TB to 5TB.

Notable firsts include executing the first smart brownfield migration to the cloud for a North American utility company and launching the first large instance of SAP S/4HANA for a utility client on Azure.

Technology changes so fast that another systems update will likely be required by 2030, if not sooner. Arrk Groupwill be there to support the needed change as PHI’s official long-term strategic partner.
