Background & Context

JERA is Japan’s largest power generation company, supplying approximately 30% of the country’s electricity and operating one of the world’s largest LNG portfolios. With 59 GW of domestic capacity, operations across multiple continents, and a public commitment to achieve net-zero CO₂ emissions by 2050, JERA plays a central role in national energy security and the global energy transition.

As JERA expanded internationally, scaling renewable investments and overseas generation projects, the organization required a modern, standardised finance foundation capable of supporting global growth, strengthening governance, and enabling faster decision-making in dynamic energy markets.

Finance needed to evolve from regionally diverse processes to a harmonized, scalable operating model aligned with global standards while continuing to support business expansion.

The Challenge

JERA faced several interconnected business challenges:

  • Aligning regional entities to global governance and reporting standards
  • Establishing independent yet harmonized finance functions across Asia
  • Increasing transparency and traceability in regulated environments
  • Accelerating month-end reporting and improving data visibility
  • Reducing manual effort and operational risk
  • Building a scalable platform to support future subsidiaries and investments

In fast-moving LNG and power markets, delayed financial insight constrains strategic agility. JERA required near real-time visibility, stronger controls, and a future-ready operating model.

“Finance is a key enabler of JERA’s global growth strategy. As we continue to expand internationally, it became essential to transition from diverse regional processes to a globally integrated and scalable operating model. This transformation not only improves efficiency and visibility, but also reinforces governance, standardizes controls, strengthens compliance, and provides a more robust framework for managing risk and performance worldwide”

Yosuke Abe, Executive Officer, Head of the Financial Strategy and Planning Group , JERA Co., Inc.

The Solution

JERA Asia partnered with Capgemini to modernize its finance operations through the implementation of SAP S/4HANA Public Cloud across Asia.

The transformation focused on:

  • Establishing a standardised global finance framework
  • Aligning entities to a Global Chart of Accounts
  • Embedding stronger governance, compliance, and traceability
  • Automating core finance processes, including bank payments and reconciliation
  • Accelerating financial close and reporting cycles
  • Creating a scalable cloud-based platform for future expansion

The cloud operating model aligns with SAP standards, reduces technical debt, and enables controlled adoption of biannual SAP releases positioning JERA for continuous innovation with minimal disruption.

This was not simply a system deployment. It was a finance operating model transformation designed to support long-term growth and resilience.

“This transformation was about more than implementing a new platform, it was about co-creating a finance operating model designed for scale. Working closely with JERA, we built a standardised and future-ready foundation that aligns with their global ambitions while remaining flexible enough to grow with the business.”

Tangible Business Outcomes

The transformation delivered measurable improvements across efficiency, governance, visibility, and scalability.

Accelerated Month-End Close 

Structured processes and automation reduced manual intervention and improved reporting timelines, strengthening accuracy and audit readiness.

End-to-End Bank Automation

Payments are now automated, transmitted, and reconciled within S/4HANA, reducing operational risk and improving accuracy and control.

Enhanced Governance and Compliance

Standardised structures across entities strengthened audit trails, improved data integrity, and reinforced internal controls critical for a global energy organization.

Financial Visibility

Embedded analytics tools provide near real-time insight into financial performance, enabling leadership to make faster decision.

In a highly complex energy market, improved visibility directly supports strategic agility.

 Scalable Platform for Growth 

The cloud-based architecture enables:

  • Faster onboarding of new subsidiaries
  • Simplified lifecycle management
  • Reduced infrastructure complexity
  • Readiness for future AI-enabled reporting and analytics

Strategic Impact 

These improvements at JERA Asia contribute to JERA’s broader global finance and investment capabilities:

  • Enhance financial insight
  • Strengthen governance and control
  • Operate with greater speed and resilience

For a company responsible for nearly one-third of Japan’s electricity supply, finance transformation is not operational housekeeping, it is a strategic initiative enabling faster, more informed decisions that support energy security.

“By implementing SAP across our overseas operations, JERA has established a unified and scalable global finance platform that standardizes processes, strengthens governance, and enhances transparency across regions. This provides a single source of truth for financial information, improves risk management and compliance, and enables more timely and data-driven decision-making. Looking ahead, the platform serves as a strong foundation for further business growth, operational excellence, and the effective management of an increasingly global and diversified portfolio.”

Yosuke Abe, Executive Officer, Head of the Financial Strategy and Planning Group, JERA Co., Inc.

The Partnership 

Since 2018, Capgemini has supported JERA across IT strategy, PMO services, and global digital transformation initiatives. The finance transformation builds on this long-term relationship, extending collaboration across Japan, JERA Asia, JERA Australia, and global subsidiaries.

Together, JERA and Capgemini continue to evolve the operating model  ensuring the organization remains agile, compliant, and positioned for expansion in an increasingly complex energy landscape.
