FORTUNE 100 US ENERGY LEADER

How a Fortune 100 Energy Leader Modernized Workforce Analytics Across 33,000+ Employees

Customer Background

A Changing Workforce in a Dynamic Market

This Fortune 100 energy leader powers millions of homes and businesses across the United States. Managing over 33,400 employees, ranging from unionized field technicians and plant operators to corporate strategists, requires continuous operational clarity. For teams facing a similarly large-scale PeopleSoft-to-Oracle Fusion HCM transition, DataTerrain's PeopleSoft-to-Oracle Fusion HCM conversion framework uses the same migration approach applied here.

The Challenge

The Legacy Challenge

To modernize HR operations, the energy provider initiated a strategic transition from its legacy PeopleSoft HRMS platform to Oracle Fusion HCM. While the core HR migration proceeded smoothly, the organization faced a major hurdle: decades of custom PeopleSoft reporting logic had to be rewritten for Oracle Cloud.

In power generation and grid transmission, reporting delays or calculation errors carry severe operational risks:

Shift Differential Calculations

Premium pay for night, weekend, and hazardous-duty shifts had to be computed correctly under both union and non-union rules, with no room for a payroll dispute during peak grid demand.

Multi-State Tax Compliance

Employees working across multiple state jurisdictions, common for field crews responding to outages, required accurate, state-specific withholding calculated automatically rather than reconciled after the fact.

Union Rules Processing

Collective bargaining agreements varied by role and region, so seniority rules, overtime eligibility, and grievance-related pay adjustments all had to be reflected precisely in every pay cycle.

Workforce Safety Visibility

Field managers required real-time visibility into workforce safety certifications and shift availability to maintain uninterrupted grid reliability.

Our Approach

The Migration Journey: Partnering for Transformation

The decision came down to specialized capabilities: DataTerrain offered an extensive repository of pre-built Oracle HCM templates, a proven zero-defect methodology, and direct "Oracle Connect" channels for fast-tracked vendor support. Our broader Oracle HCM Report Migration and Development practice applies this same automation-driven approach to organizations of any scale.

1

Re-Imagining Analytics Needs

Rather than simply duplicating legacy PeopleSoft layouts, DataTerrain worked closely with business stakeholders to reimagine reporting using native Oracle Cloud capabilities. Every report was audited, mapped, and assigned to the most appropriate tool in Oracle's reporting suite.

2

Multi-Tier Architectural Build

DataTerrain deployed a three-part architecture to handle distinct operational needs:

BI Publisher, pixel-perfect documents: custom layout engines for formal payroll slips, tax documents, and regulatory filings, built for payroll and finance teams.
HCM Extracts, high-volume data pipelines: automated outbound data feeds to external benefit carriers and third-party vendors, built for benefits and systems admin teams.
OTBI Dashboards, self-service visual analytics: interactive, embedded visual dashboards with real-time drill-down capabilities, built for HR executives and field managers.

3

Zero-Defect Validation and Production Cutover

Using programmatic validation tools, DataTerrain verified millions of payroll and workforce data points against historical sources. Any technical platform queries were managed directly with Oracle product engineering through DataTerrain's Oracle Connect liaison, ensuring zero cutover delays. This same reconciliation discipline underpins our SAP BO-to-OBIEE migrations for organizations moving off other legacy platforms.
