Case Study

ATCO Oracle Hyperion Implementation


Prior to Hyperion Implementation:

Energy conglomerate ATCO operates worldwide in utilities, power generation, and related services. The majority-owned Canadian Utilities oversees most of the group's energy businesses, including ATCO Electric and ATCO Gas (transmission and distribution) and ATCO Power (generation). Other holdings include gas gatherer and processor ATCO Midstream, and gas transporter ATCO Pipelines. ATCO I-Tek provides IT, billing, and customer care services. ATCO Structures & Logistics manufactures modular buildings and provides logistical and noise abatement services. Utilities ATCO Electric (with nearly 207,000 customers) and ATCO Gas (with more than 1 million customers) account for the largest slice of ATCO's revenues.

The ATCO Group had been using Hyperion Financial Management (HFM) to manage its Financial Consolidation and Reporting Process since the mid-2000s. Up until 2011, the ATCO environment was run on the Hyperion System 9 platform. This environment contained multiple HFM applications to support reporting requirements of various ATCO subsidiaries as well as Corporate Reporting. Due to significant performance latency, their ability to close their monthly financials in a timely manner was jeopardized. Soon, it was discovered the larger challenge was how to handle an enterprise upgrade when Oracle moved to the next generation of Hyperion.

Solution :

MindStream performed a full infrastructure assessment to determine if additional steps could be taken to improve the overall performance. The engagement began by initially providing optimization recommendations, but ultimately resulted in continued development of an Oracle Hyperion Center of Excellence.

Initial infrastructure improvement recommendations operated to stabilize the environment and, subsequently, the performance for year-end reporting. The applications were also initially reviewed to determine application optimizations. Although the environment was stabilized by network configuration updates and additional server capacity, this solution scratched the surface of a larger issue: support for the current software version was being terminated by Oracle, and a plan of action was required. As a result, the recommendations detailed a dual-phased approach:

1. Upgrade the environment to the latest generation for the Hyperion Product Suite (then, System 11). 2. Perform a detailed review of the HFM applications and ATCO Financial Close and Reporting process to determine how to streamline the applications (and potentially consolidate them), as well as make recommendations to facilitate the system reporting into IFRS and away from Canadian GAAP, which from an Accounting standard had already been converted over the previous course of years.

The Upgrade to System was completed in 2012. ATCO added Hyperion centric monitoring tools (i.e., Accelatis), to significantly improve environment stability, become compliant with current Oracle support, and stabilize the Disaster Recovery process to ensure full availability of the Hyperion environment. Then, MindStream completed a full optimization of ATCO's Financial Reporting platform as a next step in completing a developing Hyperion Center of Excellence.


MindStream not only handled the upgrades, but ultimately helped ATCO develop a comprehensive strategic financial reporting transformation. The organization and its key stakeholders seized the opportunity to create best practices across the organization for their Hyperion applications.

    Benefits included:
  • Stabilized and upgraded application environment
  • Streamlined business calculations (rules)
  • Streamliend jounrals process
  • Improved security
